What is actually stored on your device
| What | Where | Why | How long |
|---|---|---|---|
| Your session token | Local storage | To keep you signed in | Until you sign out |
| Your encryption keys | Local storage | To read your own messages; the private key never leaves the device | Until you sign out or delete the app data |
| Your messages | IndexedDB | So the app works offline | Until you delete the account or clear the site's data |
| Preferences (theme, muted chats, archived chats, audio device) | Local storage | So the app behaves the way you left it | Until changed |
| Unfinished recordings | IndexedDB | So a crash mid-recording does not lose it | Until sent or discarded |
| Push subscription | Browser push service | To ring your phone for a call | Until you turn notifications off |
| A random install id | Local storage | Sent with requests so a banned account coming back on the same device can be noticed. It identifies the browser to us, nothing else, and is never used for ads or analytics | Until you clear the site's data |
Consent
Everything above is strictly necessary to provide the service you asked for, which is why there is no cookie banner: there is nothing here to consent to that you have not already asked for by using the app. If we ever add anything that is not strictly necessary, we will ask first.
Clearing it
Signing out ends the session. The copy of your messages on this device is kept, under your account, so it is there when you sign back in — on a device other people use, clear the site's data as well. Deleting your account removes it, and your browser's site-data controls clear everything.
What has changed
9 October 2026 · version 3
- A random install id in local storage, sent with requests, so a banned account coming back on the same device can be noticed. It identifies the browser to us and nothing else, and is never used for advertising or analytics.
24 September 2026 · version 2
- Your messages are now kept in the browser's IndexedDB rather than its local storage, which is far larger, so a long history no longer fills it up.
- CORRECTION. This page said signing out clears the local copy of your messages. It does not, and did not before: the copy stays on the device, under your account, so it is there when you sign back in. Deleting your account removes it, and so do your browser's site-data controls.
