The website

This website uses no cookies, analytics, advertising trackers, forms, accounts, or fingerprinting. Source labels on links may be passed to the App Store when you follow them.

The app

MARTIN needs no account and does not collect names, email addresses, contacts, precise location, advertising identifiers, clipboard content, screenshots, or screen recordings.

The app may send a small set of anonymous product events to an EU-hosted analytics service. These events use a random installation identifier and stable story or notification IDs. They do not contain Martin's displayed text, and they are not used for advertising or tracking across apps and websites. Analytics failure never changes the app.

MARTIN keeps a near-term notification schedule on the device. If remote delivery is enabled, it also creates an anonymous notification record containing a random installation ID, an Expo push token, platform, timezone and UTC offset, story version, stable notification IDs, and intended timestamps. It contains no name, contact details, precise location, advertising ID, or text entered by a person. The installation secret is kept in the device Keychain or Keystore; the server stores only its one-way hash.

The notification service uses EU-hosted Supabase infrastructure, Expo Push Service, and the Apple or Google notification service for delivery. MARTIN sends exact authored notification text to these providers only when that notification is due. A provider acceptance does not prove that a notification reached or was read by a person.

A disabled or invalid push token is overwritten immediately. Inactive installation records are deleted after 30 days, and terminal delivery metadata after 90 days. Story updates are downloaded from a signed, read-only content feed. No account is created, and notification data is not used for advertising or cross-app tracking.
