ReplyBridge helps Instagram Business and Creator accounts respond when people comment on your posts. Connect through the app and use two complementary flows: Auto DM sends a private Direct message (Private Reply) in line with Meta’s rules, and Auto Reply posts a public comment reply that everyone on the thread can see. What you can do - Auto DM: Private follow-up to commenters via Instagram Direct, with optional keyword matching and a β€œonce per person” option per post. - Auto Reply: Automatic public replies on top-level comments, with its own message, keyword rules, and optional once-per-person limit. - Shared automation period: DM and Reply automation share one expiry window per post; you can see when it ends and, where offered, watch a rewarded video ad to extend the period. - Local reminders: Optional notifications around your automation period so you are less likely to miss renewals. - At-a-glance stats: Per post, see how many messages or replies were sent and how many distinct commenters were reached (where tracking applies). - Utility-first UI: Recent posts, search, pull to refresh, and pagination to manage many pieces of content. Important - An Instagram Business or Creator account and appropriate Meta app permissions are required. - Public comment replies are visible on Instagram; private DMs follow Meta Private Reply policies. Delivery and feature availability depend on Meta’s platform policies and your account status. - Rewarded ads are provided by Google AdMob where configured; you can choose whether to watch. The app may show other ads according to your AdMob setup. - ReplyBridge works with the ReplyBridge service; some capabilities require server-side configuration and a stable network connection.

graygate is an end-to-end encrypted messenger built for privacy. Messages are encrypted on your device before they are sent, and the server can only relay ciphertext. It gives people a way to talk safely even where free expression is suppressed. WHAT THE SERVER DOES NOT KNOW β€’ Your private key is created on your device and never leaves the iOS Keychain. β€’ Room keys are derived from the room password on each device. The server holds only a hash to check whether the password is correct. β€’ Encrypted messages wait on the server for at most 14 days so the recipient can pick them up. Once delivered, they are deleted immediately. β€’ Push notifications carry no content, no sender and no room name. Only the fact that something new arrived. LEFT OUT ON PURPOSE β€’ No read receipts. Delivery is the last thing reported. β€’ No online or typing indicators. β€’ No cloud backup. Conversations live on your device only. β€’ No ads, no analytics, no phone number, no social login. PROTECTION ON THE DEVICE β€’ App lock with Face ID, or an app PIN on devices without biometrics. β€’ Content is hidden in the app switcher, and a screenshot taken inside a room is announced to that room. β€’ Auto-delete per room: 1, 7 or 30 days. β€’ Key fingerprint check: compare 12 words and a group of digits to catch a server that tries to swap keys in the middle. ROOMS β€’ One-to-one chats, group rooms, and channels where an admin posts and members reply with comments. β€’ Photos and videos are encrypted the same way as text. Videos are saved to your album rather than played inside the app. β€’ Removing a member always rotates the room key, so they cannot read anything that follows. GOOD TO KNOW β€’ graygate is invite-only. You need an invite code from an existing user to create an account. β€’ If you switch devices, your past conversations do not follow you. That is by design. β€’ A 12-word recovery phrase resets your password and app PIN. It does not bring back past conversations. β€’ Who joined which room, and when a device connected, is stored on the server. Per-message forward secrecy is not provided. β€’ You must be at least 16 years old to use graygate. Terms of Service: https://graygate.app/terms/ Privacy Policy: https://graygate.app/privacy/
