# Unsay

> Unsay ships two separate Chrome extensions that bulk-unsend your outgoing messages: one for **Instagram DMs**, one for **Facebook Messenger**. Each is free up to a weekly quota, with an optional one-time Pass (no subscription) that unlocks unlimited unsends and Stealth Mode. The Instagram section is below first, the Messenger section follows.

> **Unsay for Instagram** : Chrome extension that bulk-deletes outgoing Instagram DMs from both sides via Instagram's own unsend mechanism (REST direct_v2 to read the thread, Instagram's official unsend mutation to delete). No DOM scraping, no mobile app, no phone reconnect. Free for 50 messages per rolling week. A one-time Pass ($30 for 7 days or $60 for 30 days) unlocks unlimited deletion, Stealth Mode, and full conversation backup as a local ZIP, then expires on its own. No subscription.

## Key facts

- **Free tier** : 50 message deletions per rolling week. Backup saves only the user's own messages.
- **Passes (one-time, no subscription)** : 7-day Pass $30 (launch offer, regular $60), 30-day Pass $60 (launch offer, regular $120). Each Pass unlocks everything, unlimited deletions, Stealth Mode (oldest-first deletion order so the recent, visible part of the chat stays intact longest), full conversation backup including the other person's messages and media, then expires on its own. The clock starts on key activation, not purchase. One Pass covers one machine. Nothing to cancel.
- **Stealth Mode** : Pass-only. Deletes oldest-first, in chronological order, so the recent part of the thread stays intact until the end. Deletion is paced at a randomized 5 to 7 seconds per message in every mode, with adaptive back-off. Useful for clearing 5-year DM histories without raising flags.
- **Backup as local ZIP** : generated entirely in the browser via the fflate library, delivered through a local download. Contains an HTML reader, photos at full resolution, voice notes (m4a), videos, and reels metadata. Never uploaded to any server.
- **Privacy local-first** : no message content stored anywhere (not locally, not on a server). Quota and license tracking server-side via a hashed Instagram user ID (SHA-256 of ds_user_id) and a per-installation UUID. No personally identifiable information. Backend stack : Cloudflare Worker + D1 (SQLite), EU region.
- **Both-sides deletion** : removes messages from the user's view and the recipient's view because that is how Instagram's native unsend endpoint works.
- **Reaches old messages** : uses the REST direct_v2 endpoint (not DOM), so messages from 2018 or earlier are reachable. Competitors that scrape the DOM cannot see messages unloaded by Instagram's virtual scrolling.
- **Compatibility** : Chrome, Edge, Brave, Opera (Chromium 114+).
- **Payment** : Lemon Squeezy. One machine per license.

Five reasons there is no bulk unsend : Unsend was designed as a regret button (Messenger's head said most retractions happen within a minute), unsent messages must stay reportable, the Terms of Use forbid automated access, the public Messaging API documents no delete operation, and an unpublished per-account rate limit blocks fast deletion (temporary action block, not a ban). Solution : Instagram's own Unsend, one by one, at a 5 to 7 second pace, from the user's session, after a backup (Unsay).

## Unsay for Messenger (Facebook)

> Separate Chrome extension that bulk-unsends your outgoing Facebook Messenger messages for everyone, including end-to-end encrypted and migrated conversations. Works on messenger.com and facebook.com/messages. Free for 50 messages per rolling week. A one-time Pass ($30 for 7 days or $60 for 30 days) unlocks unlimited unsends and Stealth Mode, then expires on its own. No subscription. The Messenger extension has no backup feature (that is Instagram-only).

### Key facts (Messenger)

- **Free tier** : 50 message unsends per rolling week.
- **Passes (one-time, no subscription)** : 7-day Pass $30 (launch offer, regular $60), 30-day Pass $60 (launch offer, regular $120). Each Pass unlocks unlimited unsends and Stealth Mode (oldest-first order, randomized 5 to 7 second pacing), then expires on its own. The clock starts on key activation, not purchase. One Pass covers one machine. Nothing to cancel.
- **Remove for everyone** : uses Messenger's native "Remove for everyone" action, so messages disappear from the user's side and the recipient's side, permanently.
- **End-to-end encrypted and migrated chats** : Messenger now defaults to end-to-end encryption. Conversations that predate encryption are split into two threads (a legacy thread and an encrypted thread). Unsay finds both, merges the count, and unsends across the whole history, something you cannot do by scrolling. The encryption is never broken : Unsay never reads message content, it only asks Messenger to remove the messages you sent.
- **No backup** : unlike the Instagram extension, the Messenger extension does not include the ZIP backup feature.
- **Privacy local-first** : no message content stored anywhere. Quota and license tracking server-side via a hashed Facebook account ID and a per-installation UUID. No personally identifiable information. Backend : Cloudflare Worker + D1 (SQLite).
- **Compatibility** : Chrome, Edge, Brave, Opera (Chromium 114+). Payment : Lemon Squeezy. One machine per license.

## Brand context

### Who

Unsay is built by a solo independent developer. No team, no investors, no VC funding. Built alone after wanting to wipe a 5-year Instagram DM history without losing the receipts.

- Contact : contact@unsay.me

### Why

Existing Instagram unsend tools have two structural limits :

1. **DOM scraping misses old messages.** Instagram's web client uses virtual scrolling (virtuoso) which unloads old DOM nodes. Any extension relying on the DOM cannot see messages older than what's currently rendered. For a 5-year conversation, that means most of the history is invisible.
2. **No backup before deletion.** Most tools delete without offering a way to archive the conversation first. Once deleted, the conversation is gone from both sides forever.

Unsay solves both by calling Instagram's own endpoints directly (the same APIs the Instagram web app uses internally), paginating from newest to oldest with the official cursor. Every message is reachable. And the local ZIP backup runs before deletion, archiving the full conversation including media.

### How it's coded

- **Manifest V3 Chrome extension.** No declared content script, no DOM scraping. The service worker reads only the active tab URL to extract the thread ID, and performs the unsend in the Instagram tab's own context at deletion time (same-origin action, under the user's existing session).
- **REST direct_v2** to read and paginate the conversation; Instagram's official unsend mutation to delete. Headers are captured dynamically via `chrome.webRequest.onBeforeSendHeaders` so the extension reuses the user's existing Instagram session without re-auth.
- **Side panel UI** (Chrome 114+) persistent across tabs. Replaces the standard popup that closes on defocus.
- **Service worker job state manager** with strict mutex so only one scan or one unsend runs at a time. State persisted in `chrome.storage.session` and rehydrated on boot.
- **Offscreen document + fflate** for the ZIP backup (service workers in MV3 have no `URL.createObjectURL`). Voice notes fetched from `cdn.fbsbx.com` (Facebook Static Binary eXchange), the actual CDN that hosts Instagram voice notes.
- **Backend** : Cloudflare Worker + D1 (SQLite) for quota and license tracking. License validation via Lemon Squeezy API server-side. The client never sees Lemon Squeezy API keys.
- **Privacy by design** : no message content ever leaves the user's browser. The server only stores a SHA-256 hash of the Instagram user ID and a per-installation UUID for quota tracking.

### Differentiators

Compared to other Instagram unsend tools :

- Only tool that reaches messages older than Instagram's virtuoso scroll wall (because it uses REST direct_v2, not the DOM).
- Only tool that exports a full local ZIP backup with an HTML reader before deletion.
- Chrome extension, not a mobile app : no phone reconnect, no OAuth re-authorization, no extra account.
- Stealth Mode (oldest-first deletion) for discreet bulk cleanup, unlocked with any Pass (7-day $30 or 30-day $60).
- Open about its stack and limits. No fake reviews, no fake screenshots.
