Privacy

Last updated 23 October 2026. Marsa is in beta, so this page changes as Marsa does; the date says when.

In short. Your messages, voice notes, photos and videos are end-to-end encrypted on your phone: our server carries them and cannot read them. So are Marsad posts, except while Marsad is open to everyone as a test. We keep what is needed to run your account and deliver your messages. You can delete your account at any time.

Marsa (“we”, “us”) is responsible for the personal data described here. This page says what Marsa keeps, why, and for how long. The terms of use and the community rules go with it.

What our server keeps

Your account

A username, your role, and a one-way hash of a sign-in proof that your phone makes from your passphrase: the passphrase itself never leaves your phone. (Accounts made before 23 October 2026 also keep, for a while, the older one-way hash of the passphrase, so that older copies of the app can still sign in.) For each phone or browser you sign in on: a session, the kind of device and browser, when it was last used, and which version of Marsa it runs. To stop abuse, sign-ups and requests for help getting back in are counted per connection for one day; we keep only a one-way code made from the internet address and the day, never the address itself, and it means nothing the next day. Our hosting keeps a record of errors for a few days, not a log of each visit.

Messages and posts

End-to-end encrypted. The server keeps your public keys, who you have accepted as a contact and the code they used, the groups you are in, and the encrypted messages until your devices fetch them (unfetched ones go after 30 days). It also sees when a message was sent and how large it is, never what it says. Photos, videos and voice notes are encrypted on your phone and kept for up to 30 days; view-once media goes when it has been opened.

Your keys and chats in your account

Unless you turn it off (Chat settings › Keys and message history), your chat keys and a copy of your chats are kept in your account, locked with a key your phone makes from your passphrase, and with your recovery key if you make one. That is how signing in on a new phone brings everything back. We cannot open them. If Marsa's team resets your passphrase, they stay locked with your earlier passphrase or your recovery key.

Things you choose to keep in your account

Your family tree in Lafifa, trips, places, the travel log, the guide and your settings are kept so they stay the same on all your devices. They are encrypted on your phone before they leave it, with a key that travels with your chat keys, so our server cannot read them: it sees only when each was last changed and how large it is, and the names of your settings (not their values). Saved Marsad, if you keep a copy in your account, and the names in your address book are encrypted the same way. If you turn off keeping your keys in your account, a new phone gets them only by linking it from one you already have.

What is not end-to-end encrypted

Other records

Your Marsa tokens and handles; the reach codes you make and when they were used (shown to you as “How we met”); requests for help getting back in; appeals; and a moderation record of what our team decided about reports and accounts.

Kept only on your phone

Your location: prayer times, the qibla, the country you are in and the home you set are all worked out on the phone. Files you attach to a trip, your audio in Listen, and Saved Marsad (unless you keep a copy in your account). Your chat history is kept on your phone too, sealed with a key that stays on the device.

Services your phone or our server use

We report child sexual abuse material to the authorities.

Requests for information

We give information to an authority only when the law that applies to us requires it. What our server holds is listed on this page: an account's username and role, when it was made and last used, its devices' kinds and app versions, who it is connected to and in which groups, when messages were sent and how large they were, its tokens, handles and codes, and what is not end-to-end encrypted (open Marsad posts while they last, reports, feedback, what was sent to the assistant or a bot). Messages, photos, videos, voice notes, chat keys, your family tree, trips, travel log and settings are encrypted so that we cannot open them, so we cannot give them to anyone.

Your choices

Deleting your account

In the app: Marsa › Delete my account. Without the app: open marsa.chat/#delete-account, sign in and confirm with your passphrase. Everything kept for your account is deleted at once: synced data, keys and devices, contacts, codes, handles, tokens, media, backups and Saved Marsad. Your contacts' phones are told the account was deleted.

Kept for everyone's safety: reports other people made about the account and the moderation record (reports you made stay, without your name). A picture or video attached to a report about a child's safety is kept for one year in case the authorities need it, then deleted.

Children

Marsa is for people aged 18 or older. If we learn that an account belongs to someone younger, we close it. Lafifa lets you record relatives, children among them: those records are private to you, and the app asks before anything leaves your phone.

Security

Messages, and the data your phone keeps in your account, use end-to-end encryption; passphrases and recovery keys are kept only as one-way hashes; sign-in attempts are limited. No system is perfectly safe: keep your passphrase and recovery key to yourself.

Questions

Use Feedback in the app (Marsa › Feedback). For a question about your data, or to ask us to correct or delete something, write there and we will answer.
