The Threads tab shows message threads (replies grouped by origin message). Open a thread from the chat screen to see all replies in context. Threads keep conversations organized and make it easy to follow replies to a specific message.

Tap a message in the chat to open its thread. The thread tab displays the original message and all replies. You can reply inside the thread — replies are visible both in the thread and (optionally) inline in the group chat depending on group settings.

The Agent is an optional assistant integrated in chat. It can answer questions, summarize conversations, and help find relevant organization FAQs. Trigger the Agent by mentioning it in a chat or using the assistant button in the chat screen. Agent responses use organization-scoped FAQ context when available.

To edit a message you've sent:

• Long-press (or press and hold) the message you want to edit
• Select "✏️ Edit" from the menu
• Update the text and tap "Save"
• The message will be updated for all group members
• An "(edited)" label appears below the message so others know it was changed

To delete a message:

• Long-press the message
• Select "🗑️ Delete" from the menu
• Confirm the deletion in the alert
• The message will be removed from the chat for all members

Typing indicators show you when others are typing:

• When someone starts typing, you'll see "Alice and Bob are typing..." at the bottom of the chat
• This helps you know a reply is coming
• The indicator automatically disappears 3 seconds after they stop typing
• Works in real-time across all members in the group

Read receipts show you who has read your messages:

• After you send a message, it displays "✓✓ Read by X" when members view it
• The number shows how many people have read your message
• A message is marked as read when it becomes 50% visible on someone's screen
• Tap the read receipt to see details about who read it and when

See who's online in a group:

• Open the group and tap "Group Info" or the info icon
• Look at the members list
• 🟢 Green dot = Member is currently online
• ⚫ Gray dot = Member is offline
• Status updates in real-time as members come online or go offline

Yes, you can mute specific users in a group:

• Open the member's profile from the group
• Tap "Mute User"
• You won't see messages or typing indicators from this user
• To unmute, open their profile and tap "Unmute User"

Messages can disappear for several reasons:

• Auto-Delete Policy: Group admins can set a message retention policy (e.g., delete after 7 days). Old messages are automatically deleted.
• Manual Deletion: You or a group admin deleted the message
• Moderation: A message was removed for violating group rules
• Sync Issues: In rare cases, messages may not sync properly—try closing and reopening the chat

Check with the group admin if you're unsure about a deleted message.

The Replies tab (available in the Group List screen) aggregates recent replies across groups you follow. It helps you catch up on conversations where you were mentioned or replied to without opening each group individually.

Broadcasts let admins send announcements to all members in a group or organization. Use the Broadcast action in Group Info or the Admin Panel. Recipients will see the message marked as a broadcast. Only admins can create broadcasts.

Each member in a group has a role:

• Admin: Can manage members, set group rules, delete messages, manage settings
• Member: Can send and edit their own messages, see group chat history

The person who creates a group is automatically the admin. Admins can promote other members to admin if needed.

As a group admin, you can manage members:

• Open "Group Info" and go to "Members"
• Tap a member to see options:
  • Promote to Admin: Give them admin permissions
  • Remove Member: Kick them from the group
• Removed members can rejoin if they have the group ID

As a group admin, you can modify group settings:

• Open the group and tap "Group Info"
• Edit the group name and description
• Set or update group rules
• Configure message retention (auto-delete) policy
• Choose who can see chat history

All changes apply immediately to the entire group.

Group rules help set expectations for member behavior:

• Admins can create custom rules when setting up the group
• Rules are displayed to all members in the "Group Info" section
• Examples: "No spam", "Be respectful", "No links to external sites"
• Rules are enforced through moderation—admins can delete messages that violate rules

To leave a group you're a member of:

• Long-press the group in your chat list
• Select "Leave Group"
• Confirm that you want to leave
• You'll be removed from the group immediately

Yes, group admins can delete a group:

• Open the group and tap "Group Info"
• Scroll to the bottom and select "Delete Group"
• Confirm the deletion
• The group and all its messages are permanently deleted

Your messages have multiple layers of protection:

• Access Control: Only members of a group can see that group's messages
• Admins Cannot Read: Admins cannot decrypt and read your messages
• Row-Level Security: Database rules enforce that you can only access appropriate messages
• Encryption at Rest: Messages are encrypted when stored on our servers

Message retention is an automatic deletion feature for groups:

• How it works: Admins can set a retention period (e.g., "Keep messages for 7 days")
• Automatic deletion: Messages older than the retention period are automatically deleted
• Options: Keep Forever, 24 hours, 7 days, or 30 days
• What gets deleted: Message text, media files, and reactions

This helps protect privacy by removing sensitive conversations automatically.

When a retention policy is set, deletion happens in multiple ways:

• Immediately: When the admin changes the retention policy, all older messages are deleted right away
• Hourly: Every hour, messages that have naturally expired are automatically removed
• On load: When you open the chat, any expired messages are cleaned up

This ensures old messages don't stay around longer than intended, even if the app isn't actively used.

NextzChat analyzes messages locally on your device for features like:

• Sentiment Analysis: Detects the emotional tone (positive, negative, neutral) for conversation statistics
• Intent Detection: Identifies if a message is a question, greeting, statement, etc.
• Language Detection: Recognizes which language your message is in

Privacy: All analysis happens on your phone—no data is sent to external servers. The results are only used to generate group statistics, never shared with others.

NextzChat collects minimal personal information:

• Required: Display name (for the app to work)

Organization-scoped FAQs are managed at the organization level so every member can use them. To upload FAQs for an organization:

• Open the Admin Portal or Organization Settings for the target organization.
• Use the "FAQ Upload" option to import a CSV or JSON file, or use the in-app OCR/FAQ importer if available.
• When importing, choose the "Organization" scope (not "Individual") so the FAQs are visible to all org members.
• After upload, the system generates embeddings and the Agent will use these org FAQs for contextual answers.

If you don't see the upload option, ask an organization admin to perform the import or grant you the required role.

An organization is a container for your community, teams, or groups:

💡 Tip: The Agent pulls organization-scoped FAQs when available to give faster, consistent answers.

The Agent is an optional in-chat assistant that can answer questions, summarize conversations, and find relevant organization FAQs. It's designed to help members get quick, contextual responses without leaving the chat.

Trigger the Agent by:

• Mentioning the Agent in chat (e.g., @agent what is our refund policy?)
• Tapping the assistant / help button on the chat screen
• Using Quick Actions or the search bar where available

The Agent prioritizes organization-scoped FAQs (if uploaded) and recent conversation history. If organization FAQs are available, the Agent uses those embeddings to produce more accurate, consistent answers for members of that organization.

The Agent operates within your deployment's privacy rules. For this project:

• Organization FAQs are processed into embeddings — no raw user messages are uploaded unless explicitly allowed.
• Agent responses may reference public org FAQs and recent chat context only.
• If you require different privacy controls, ask your admin to disable/limit Agent features in the Admin Portal.

Organization admins can:

• Enable or disable the Agent for the organization
• Upload or remove organization-scoped FAQs that the Agent uses
• Set rate limits or restrict which groups can invoke the Agent

If you don't see Agent controls, ask an organization admin to check the Admin Portal.

Your messages are protected by multiple layers of encryption:

• In Transit: All messages sent from your phone to our servers use HTTPS/TLS 1.3 encryption. This prevents anyone from intercepting your messages while they're being sent over the internet.
• At Rest: Messages stored on our servers are protected by database encryption and Row-Level Security policies, ensuring only authorized group members can access them.
• Access Control: Only members of your group can view messages in that group. Admins cannot decrypt and read your messages.

HTTPS/TLS 1.3 is the industry standard for secure web communication:

• HTTPS: The "S" stands for "Secure" - it's HTTP with encryption
• TLS: Transport Layer Security is the protocol that handles the encryption
• In Practice: When you send a message, it's encrypted before leaving your phone and remains encrypted until it reaches our secure servers
• Protection: Even if someone intercepts the data, they cannot read your messages because they're encrypted

Row-Level Security is a database-level protection that ensures you can only see messages you're authorized to see:

• How It Works: Before the database returns any messages, it checks who is requesting them
• Group Check: Are you a member of this group? If no, the database blocks access
• Automatic: RLS works automatically - you don't have to do anything
• Server-Side: This protection is enforced at the database level, not just in the app

NextzChat uses server-side encryption with Row-Level Security rather than full end-to-end encryption:

• Current Security: Messages are encrypted in transit (HTTPS) and protected at rest (database encryption + RLS)
• Why: RLS provides stronger features like message search, content moderation, and admin oversight
• Trust Model: You trust the app developers and Supabase to protect your data (same as WhatsApp, iMessage, and most messaging apps)
• Trade-off: RLS allows better moderation and safety features, but requires trusting the service provider

No. Messages are protected by multiple security measures:

• Row-Level Security: Database rules prevent unauthorized access to encrypted message content
• Separation: App developers do not have direct database access to user messages
• Authentication: Only authenticated users (you) can access your own data through the app
• Encryption: Messages are encrypted - even if someone got the data, they couldn't read it without the encryption key

Your password is handled securely by our authentication system (Supabase Auth):

• Never Stored in App: Your password is not stored on your phone in plain text
• Hashing: Supabase uses industry-standard password hashing (bcrypt) which converts your password to a one-way hash
• Verification: During authentication, your password is hashed and compared to the stored hash - the original password is never stored
• Never Sent Again: After authentication, you receive a session token - your password is not sent with every request

When you enable biometric authentication, your credentials are encrypted using AES-256 encryption:

• AES-256: Military-grade encryption standard used by government agencies
• Encryption Key: Generated from your user ID and a unique salt, never stored or transmitted
• Storage Location: Encrypted credentials stored in device's secure keystore (Keychain on iOS, Keystore on Android)
• Device-Only: These encrypted credentials never leave your device - they're never sent to our servers

Messages remain encrypted for their entire lifetime on our servers:

• When Sent: Message is encrypted in transit via HTTPS/TLS
• At Rest: Message is stored encrypted in the database
• When Viewed: Database decrypts (with RLS check) only for authorized users
• When Deleted: Message is marked as deleted and eventually purged from backup systems
• Auto-Delete: If retention policy is set, message is automatically deleted after the policy period

If you suspect unauthorized access, take these steps:

• Immediately: Change your password in Settings > Account > Change Password
• Sessions: Go to Settings > Device Sessions and terminate any sessions you don't recognize
• Biometric: Disable Face ID/Fingerprint in Settings > Security and re-enable it with your new password
• Messages: All messages are still encrypted - the attacker can only see what they accessed through the app
• Support: Contact support with details about the suspicious activity

Media files use multiple layers of security:

• Upload: Files sent via HTTPS/TLS encryption - encrypted in transit
• Storage: Files stored in secure cloud storage with encryption at rest
• Access Control: Signed URLs generated only for authorized users, expiring after short period
• Scanning: Files scanned for malware and inappropriate content before storage
• Deletion: When message is deleted, associated media files are also deleted

Most data is encrypted, but some metadata is stored in plain text for system functionality:

• Metadata (Not Encrypted): Who sent a message, when it was sent, read receipts, typing indicators, group membership
• Reason: This metadata is needed for features like search, notifications, and group management
• Protected: Even though not encrypted, metadata is protected by Row-Level Security - only authorized users can see it
• Message Content: Message text IS encrypted - only metadata is in plain text

Message threads allow you to reply to specific messages and keep conversations organized:

• Reply to Message: Instead of just replying in the main chat, you can respond to a specific message
• Separate Conversation: Thread replies appear in a separate view, keeping related messages together
• Context: Each thread shows the original message and all replies to it
• Organization: Threads help organize conversations with multiple topics happening at once

To reply to a specific message:

• Tap to Open: Tap the badge to open the thread and see all replies
• Quoted Message: In the main chat, you can see a quoted preview of the original message when someone replies

When someone replies to a message in a thread:

• Main Chat: The original message appears in the main chat with a thread indicator (💬)
• Replies Hidden: Individual thread replies do NOT appear as separate messages in the main chat
• Preview Quote: You can see a preview of the original message to understand context
• Tap to View: Tap the thread indicator to see all replies in the thread
• Organized: This keeps the main chat clean and organized

Yes, you can delete your own messages within a thread:

• Your Messages: You can delete any message you sent in the thread
• Other Messages: You can only delete others' messages if you're a group admin or message moderator
• How: Long-press the message in the thread and select "Delete"
• Permanent: Deleted messages cannot be recovered
• Original: If you delete the original message, all replies in the thread are also deleted

Yes, thread replies follow the same retention policy as regular messages:

• Retention Policy: If your group has a 30-day retention policy, both original messages and thread replies are deleted after 30 days
• Auto-Delete: Thread replies are automatically deleted along with the main message when the retention period expires
• Manual Delete: Group admins can manually delete all messages in a thread or the entire thread
• Policy Change: If a group changes its retention policy, thread replies are affected the same as regular messages

Yes, thread replies have the same encryption as regular messages:

• Encryption in Transit: Thread replies are encrypted via HTTPS/TLS when sent from your phone
• Encryption at Rest: Replies are stored encrypted in the database
• Row-Level Security: Only group members can view replies in a thread
• Access Control: Same group membership rules apply - you must be a group member to see thread replies

Yes, you can get notifications when someone replies to your message in a thread:

• Automatic: When someone replies to your message in a thread, you get a notification
• Notification Content: "[User] replied to your message: '[message preview]'..."
• Settings: Go to Settings > Notifications to enable/disable thread reply notifications
• Mute Thread: You can mute notifications for a specific thread while keeping group notifications on
• Badge: Unread thread replies show a badge number on the thread indicator

Yes, you can edit your own messages in a thread:

• Edit Your Messages: Long-press your message and select "Edit"
• Edit Indicator: Edited messages show an "Edited" indicator below the message
• Edit History: Some versions show when a message was edited
• Others' Messages: Only admins/moderators can edit other members' messages
• Notification: Original poster and thread participants don't get notified of minor edits

Read receipts work in threads just like in the main chat:

• Read Status: Each message in a thread shows who has read it
• Checkmarks: Single ✓ = sent, double ✓✓ = delivered, double ✓✓ (filled) = read
• Tap for Details: Tap the checkmarks to see exactly who read the message and when
• Disabled: If read receipts are disabled in Settings, they don't appear in threads either
• Privacy: Read receipts respect your privacy settings across the entire app

Yes, you can add emoji reactions to messages in a thread:

• Add Reaction: Long-press a message in the thread and select "Add Reaction"
• Choose Emoji: Pick an emoji from the emoji picker (or it opens a reaction menu)
• View Reactions: Reactions appear below each message in the thread
• See Who Reacted: Tap a reaction to see which users added that emoji reaction
• Remove Reaction: Tap your own reaction to remove it

Thread structure is one level deep:

• Single Level: You reply to an original message, and your reply goes into that message's thread
• No Nesting: You cannot create a thread within a thread - all replies are at the same level
• Flat Structure: If you reply to a thread reply, your message still goes into the same thread
• Organization: All discussion about one message topic stays in one thread for clarity
• Simpler: This keeps threads easier to navigate and understand

NextzChat includes several intelligent AI-powered features that analyze your conversations:

These features work on-device and respects your privacy—no data is sent to external servers.

Sentiment Analysis detects the emotional tone of messages by analyzing word patterns and context:

• Positive sentiment (😊): Messages with encouraging words like "great," "love," "amazing," "awesome"
• Negative sentiment (😞): Messages with words like "terrible," "hate," "awful," "frustrated"
• Neutral sentiment (😐): Messages that don't express clear emotion
• Mixed sentiment (🤔): Messages containing both positive and negative emotions

Each analysis includes a confidence score (0-1) indicating how certain the AI is about the sentiment.

Intent Detection identifies what a message is trying to accomplish. It recognizes types like:

• ❓ Question: "What time is the meeting?" or "Do we need anything?"
• 💬 Statement: "I'm working on the project" or "The weather is nice today"
• 🎯 Request: "Can you send me the file?" or "Please review this"
• 👋 Greeting: "Hey everyone!" or "Good morning!"
• 👋 Farewell: "See you later!" or "Goodbye!"
• 😤 Complaint: "This isn't working!" or "I'm frustrated with this"
• 😊 Opinion: "I think we should..." or "In my opinion..."
• 🎉 Announcement: "Everyone, please read this!" or "Important update"

This helps organize conversations and understand communication patterns in your group.

Language Detection automatically recognizes the language of messages by analyzing character patterns and common words. It supports:

• 🇬🇧 English
• 🇪🇸 Spanish
• 🇫🇷 French
• 🇩🇪 German
• 🇮🇹 Italian
• 🇵🇹 Portuguese
• 🇷🇺 Russian
• 🇯🇵 Japanese
• 🇨🇳 Chinese
• 🇸🇦 Arabic
• 🇮🇳 Hindi

Each detection includes a confidence level (0-1) and a country flag emoji for quick visual identification.

Conversation Analytics provides insights into your group's communication patterns by analyzing all messages:

• Conversation Tone: Overall sentiment of the group (positive, neutral, negative, mixed)
• Engagement Level: How active the conversation is (low, medium, high)
• Sentiment Distribution: Breakdown of positive, negative, and neutral messages
• Intent Distribution: Types of messages being sent (questions, statements, requests, etc.)
• Topic Cloud: Most frequently mentioned keywords
• Questions Asked: Count of question-type messages
• Answers Provided: Count of answer-type messages

Yes! You can control AI features through your privacy settings:

1. Go to Settings in the app
2. Select Privacy & Security
3. Find AI Analysis Features
4. Toggle off any features you don't want to use

• Sentiment Analysis: Disable to hide emotion detection badges
• Intent Detection: Disable to hide message type badges
• Language Detection: Disable to hide language identification
• Cloud AI: Disable to use only on-device analysis (faster, no cloud processing)

Yes, AI analysis is designed with privacy as a priority:

• AI analysis processes only the decrypted text in your local app instance
• Analysis badges are generated locally, not stored in the database
• You can disable all AI features anytime in privacy settings

AI analysis accuracy varies by feature and context:

• Sentiment Analysis: 85-95% accurate on typical messages, lower on sarcasm or mixed emotions
• Intent Detection: 80-90% accurate for clear intents, variable for ambiguous messages
• Language Detection: 95%+ accurate for pure-language messages, lower for mixed-language content

Accuracy depends on:

• Message clarity: Clear, straightforward messages are easier to analyze
• Sarcasm & humor: Jokes and sarcasm can confuse sentiment detection
• Mixed content: Messages mixing multiple languages or emotions are harder to classify
• Abbreviations: Text-speak and abbreviations may affect accuracy

AI analysis can help moderators identify problem messages:

• Negative sentiment spikes: Detect when conversations become hostile
• Complaint detection: Identify complaint-type messages that need follow-up
• Spam patterns: Repetitive announcement-type messages might indicate spam
• Engagement monitoring: Track if a group's tone is becoming toxic

However, AI analysis should not be the only moderation tool:

• Always review actual message content—don't rely only on AI badges
• False positives happen—sarcasm or dark humor can be misclassified
• Combine AI analysis with group rules and human judgment
• Use analysis trends over time, not individual messages

Ollama is an optional local AI model that can enhance NextzChat's analysis capabilities:

• What it is: A local, open-source language model that runs on your device or network
• How it helps: Provides more sophisticated AI analysis for sentiment, intent, and language detection
• Privacy: Runs locally or on your private infrastructure—no data goes to external AI services
• Optional: Completely optional; the app works perfectly without it
• Advanced users: Developers and power users can install Ollama for enhanced features

• If Ollama is not available, NextzChat automatically falls back to on-device analysis
• Users don't need to install anything—it's optional for advanced setup only
• Cloud AI services are also optional for users who want them

Yes! Most AI features work offline:

• On-device analysis works offline: Sentiment, intent, and language detection work without internet
• Cloud AI requires internet: Ollama and advanced cloud features need an internet connection
• Automatic fallback: If you lose connection, the app automatically uses on-device analysis

Your analysis results are stored locally and won't disappear when offline. When you reconnect:

• The app syncs new messages with their analysis
• Any cloud AI upgrades process when connection is restored
• Analysis badges appear automatically as messages load

Here are tips to get better AI analysis results:

• Write clearly: Use complete sentences and standard spelling for better sentiment detection
• Avoid sarcasm in critical messages: AI struggles with sarcasm—be direct for important feedback
• Use single languages per message: Mixing languages lowers detection accuracy
• Include context: Longer messages with context are easier to analyze accurately
• Be specific with intent: "Can you review this?" is clearer than "What do you think?"

For group admins:

• Set clear communication guidelines for your group
• Encourage members to be explicit about intent (use "Question:" or "Request:" prefixes if needed)
• Review and trust the AI analysis trends, not individual predictions

Moderation is NextzChat's system to keep communities safe and respectful by filtering harmful content:

NextzChat uses intelligent profanity detection with multiple layers:

• Token-based matching: Detects exact offensive words, not substring matches (so "hello" won't match "hell")
• Fuzzy matching: For longer words (4+ characters), allows minor typos using Levenshtein distance
• Context awareness: Avoids false positives in jokes or historical discussions
• User control: Users see what word triggered the filter and can edit or send anyway

What happens when profanity is detected:

• If "No Profanity" rule is enabled in the group: ⚠️ User gets a warning
• Warning shows the specific word detected (e.g., "Your message contains profanity: damn")
• User can edit the message or send it anyway
• No automatic censoring—profanity is never censored or hidden from the sender

NextzChat's moderation system flags several types of content:

• 🔴 Hate speech & threats - Language targeting protected groups or threatening violence
• 🟠 Harassment & abuse - Direct insults, bullying, or targeted attacks on individuals
• 🟡 Profanity - Offensive or vulgar language (if group rule enabled)
• 📬 Spam - Repeated characters, excessive punctuation, or flooding
• 🔗 Links - URLs and web addresses (if group rule enabled)
• @️ Mentions - @username tags (if group rule enabled)
• 📊 PII - Personal information like emails or phone numbers
• 🎯 Custom violations - Anything against your group's specific rules

Not all flagged content is blocked—most get warnings allowing users to revise.

Flagged messages are handled based on the flag type and severity:

• 🟡 Warnings (low severity):
  • Message is sent to the group
  • All group members see it normally
  • Only the sender sees the warning dialog
  • Example: Profanity, links, or spam (if not blocked)
• 🔴 Blocks (high severity):
  • Message is NOT delivered to the group
  • Only the sender sees it in their chat (grayed out or marked as blocked)
  • Group members never see the message
  • Example: Threats, hate speech, or severe harassment
• 👨‍⚖️ Administrators:
  • Group admins can see a moderation log/dashboard (if enabled)
  • Admins see flagged messages for review and appeal handling
  • Admins can override decisions if needed

NextzChat includes automated spam detection to prevent flooding and abuse:

• Repeated characters: Detects "Hellooooooo" or "!!!!!!!" (5+ repetitions)
• Excessive punctuation: Flags messages with too many ?! marks (more than 5)
• ALL CAPS spam: Detects when more than 60% of message is uppercase (on messages longer than 10 characters)
• Repeated messages: Can flag if same message sent multiple times within seconds
• Rate limiting: Some groups may limit max messages per user in time windows

User experience:

• Spam typically triggers a warning, not a block
• Users are shown the specific spam reason (e.g., "Excessive capital letters")
• Users can edit the message or send anyway
• Group admins can customize spam sensitivity

Group Rules are customizable moderation settings that admins enable for their group:

• 🔴 No Profanity: Block offensive language (admin-configurable word list)
• 🔗 No Links: Prevent URL sharing (block http://, https://, www., ftp://)
• @️ No Mentions: Disable @username tags (@John, @Sarah, etc.)
• 📢 No Spam: Flag excessive punctuation, caps, or repeated characters
• 💬 Message Rate Limit: Max messages per user in a time window
• 🎯 Topic Requirement: Messages must contain certain keywords

How to check your group's rules:

1. Open your group
2. Tap the group name to open Group Info
3. Select "Group Rules & Moderation"
4. See which rules are enabled

Yes! If you think a message was blocked incorrectly:

1. In the chat, find the blocked message (it appears grayed out or marked as blocked)
2. Tap and hold on the message
3. Select "Appeal Block" or "Request Review"
4. Explain why you think the block was a mistake
5. Submit your appeal

What happens next:

• Group admins receive your appeal notification
• Admins review the message and your explanation
• You get notified of the decision (usually within 24 hours)
• If approved, the message is delivered to the group

• Common false positives: Sarcasm, jokes, or context that the AI misunderstood
• Don't reword and resend: This might count as spam—use the appeal system instead

Moderation flags come in two main categories:

Severity levels:

• 🟢 Low: Simple warnings like profanity or links
• 🟡 Medium: Harassment or targeted abuse
• 🔴 High: Threats, hate speech, or illegal content

Moderation systems are imperfect, but NextzChat has safeguards:

• Sarcasm & humor: Automated systems struggle with jokes and sarcasm—appeals help
• Context matters: "This is hell" (complaint) vs. "Go to hell" (insult) should be treated differently
• Marginalized communities: Be aware that some moderation catches reclaimed slurs—use appeals if your group uses different language norms

Admins have significant control over moderation settings:

• Disable specific rules: Turn off "No Profanity," "No Links," etc. individually
• Customize profanity lists: Add or remove words from the banned words list
• Adjust sensitivity: Set thresholds for what counts as spam (different tolerance per group)
• Override decisions: If a message was blocked, admins can manually deliver it

However, some moderation cannot be disabled:

• Illegal content: Threats, hate speech - enforced at platform level
• PII detection: Email/phone patterns are always flagged for safety
• AI moderation: Background ML-based checks cannot be fully disabled

If you see a message that violates community standards:

1. Long-press on the message
2. Tap "Report Message"
3. Select the reason:
   • 🚫 Spam or abuse
   • 🔞 Inappropriate content
   • 😠 Harassment or bullying
   • ⚠️ Dangerous or illegal content
   • ❌ Violates group rules
4. Optionally add a comment explaining
5. Submit the report

What happens:

• Group admins receive your report
• The message is flagged in the moderation dashboard
• Admins review and decide action (delete, warn, block user, etc.)
• You may get notified of the outcome

• Don't abuse reports: False reports may affect your account
• Evidence matters: Clear descriptions help admins decide faster
• Multiple reports: If many people report the same message, it gets priority

Getting repeated warnings might indicate a pattern:

• Check group rules: Make sure you understand what's not allowed
• Adjust your language: Be more mindful of profanity or tone
• Avoid spam patterns: Don't use excessive punctuation or repeated characters
• Follow the guidelines: Obey rules about links, mentions, and topics

Possible outcomes of repeated violations:

• First/second: Warning (message sent anyway)
• Third/fourth: Block or admin warning message
• Persistent: Admin may mute or temporarily remove you from group
• Extreme: Admin may permanently ban from group

Talk to your admin:

• If warnings seem unfair, message the group admin
• Explain your perspective (e.g., "I was joking," "I didn't know that was against rules")
• Ask for clarification on rules
• Request a second chance
