BlindPost
Release Notes
Every version of BlindPost, what shipped and when.
Channels, topic posts, comments, sponsor disclosure, source links, in-app reporting
A new chat type for one-to-many broadcasting. Topic posts carry title, Markdown body, up to 9 images, video, polls, and CTA buttons. Subscribers comment on topics and like both topics and comments. Sponsor disclosure renders a clear "Sponsored by …" banner separated from the body. Source links let creators credit where content came from, shown in each reader's own language. Channel owners get a 24-hour silent recall window. Long-press a member's avatar for the option to delete that user's messages locally. Long-press to report content in-app — an Acceptable Use Policy is published alongside.
Group auto-delete timer, composable burn modes, HEIC photos
Owners and admins set a chat-wide message lifetime that every member's messages follow automatically. Personal burn-after-read and burn-after-send can now coexist on the same chat, with each message using the stricter timer. The chat list masks burn-after-read content as 🔥 instead of revealing the text or filename. HEIC photos send reliably (previously rejected as "format not supported").
Tablet & phone-landscape layouts, desktop drag-and-drop, Windows notifications
Turn your phone sideways or open BlindPost on an iPad / Android tablet and chat list, conversation, and contacts lay out side by side. Drop images, videos, or documents straight into the chat window on Windows, Linux, and macOS. Windows now shows toast notifications for incoming messages, and switching between Wi-Fi and mobile data no longer leaves connections half-open.

Burn After Send, group card invitations, Windows desktop client
Pick a time when you send and the message disappears on its own — pairs with the existing Burn After Read mode. Invite friends to any group with a tap-to-join card, open or approval mode. Audio files play inline, unsupported videos fall back to the browser, and BlindPost is now on Windows 10+ alongside iOS / Android / macOS / Linux.
Reliable group history, roster IDs, smoother scroll
Group chat history now loads reliably — fixes a case where a chat could appear empty or fail to load older messages. Member, admin, and invite-friend lists show short user IDs to disambiguate same-nickname people. Scroll position stays put when new messages arrive while you're reading history.
Voice Effects, recall burn-after-read, faster delete
Pitch-shift voice effects applied locally before sending. Recall your own burn-after-read messages within the same 2-minute window as regular messages. Burn-after-read picker now spells out the rules. Long-press → Delete in the menu (no multi-select needed), plus a new Clear chat history option in the private chat menu / Group settings.
On-device translation, image OCR, Opus voice
Long-press any message or image to translate or recognize text — runs fully on-device, message text never leaves for BlindPost or any third-party server. Voice messages ship as 16 kbps Opus, ~10× smaller with no audible loss. Backup & restore overhaul: live progress, 24-hour window, scrubs device-bound keys on import.
Device-to-device migration, 100,000-member groups
One-tap account migration across iPhone / Android / Mac / Linux with sealed local Wi-Fi transfer + mandatory preflight. Up to 100,000-member groups open as fast as 100-member ones — server stores no group data or member roster; clients load member info on demand from local cache.
Multi-image grid, group nicknames, 24h Prekey rotation
2–9 photos/videos collapse into one grid bubble. Per-group nicknames. Prekey auto-rotates daily. macOS real-time group messages fix. Public release notes at blindpost.app/releases/.
3×3 action menu, 28 reactions, Prekey fingerprint privacy
Redesigned long-press menu, expanded reactions, cross-device identity verification via Prekey fingerprint. Android Downloads via MediaStore. macOS Developer ID signed + notarized. Linux x86_64 (Beta).
