# Unsay

> Chrome extension that bulk-deletes outgoing Instagram DMs from both sides via Instagram's official REST API (direct_v2). No DOM scraping, no mobile app, no phone reconnect. Free for 100 messages per rolling week. A one-time Pass ($15 for 7 days or $30 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** : 100 message deletions per rolling week. Backup saves only the user's own messages.
- **Passes (one-time, no subscription)** : 7-day Pass $15 (launch offer, regular $30), 30-day Pass $30 (launch offer, regular $60). Each Pass unlocks everything, unlimited deletions, Stealth Mode (5-7 second randomized delays, oldest-first order to avoid pattern detection), 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. Paces unsend requests with randomized 5-7s delays in chronological order so years of deletion don't look like a script. 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** : Gumroad. One machine per license.

## Brand context

### Who

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

### 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 REST direct_v2 endpoint directly (the same API 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 content script, no DOM scraping. The service worker reads only the active tab URL to extract the thread ID.
- **REST direct_v2** for all conversation operations. 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 Gumroad API server-side. The client never sees Gumroad 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 $15 or 30-day $30).
- Open about its stack and limits. No fake reviews, no fake screenshots.
