Fortress by StellarTimeLock

Privacy policy

Effective October 3, 2026. The vault is local. This page says what that means.

Who we are

Fortress is published by StellarTimeLock. The Android package is com.stellartimelock.stellarvault. Contact support@stellartimelock.com. This policy covers the Fortress Android app and this website.

Data that stays on your device

Passwords, usernames, notes, recovery codes, authenticator secrets, addresses, card numbers, and passkeys are stored only on your phone, in an encrypted save file (stellar-vault.svault) in a folder you pick. The key comes from your seed or recovery phrase. StellarTimeLock cannot open that file. We do not have an account system, and we do not receive a copy of the vault.

Fingerprint or face unlock is a shortcut on that phone. It does not encrypt the save file. If you add a fingerprint, reinstall, or change phones, Fortress asks for the seed again. A backup still opens with the seed alone.

What can leave the device

Nothing leaves the phone unless you do one of these:

Autofill and the passkey provider fill other apps on the same phone. That data is not uploaded by Fortress.

What we do not do

No ads. No analytics. No crash-reporting account. No sale of data. No advertising ID. The camera is used to scan an authenticator QR code and the picture is not saved. This website does not set tracking cookies and does not ask you to sign in.

Children

Fortress is for adults 18 and older. It is not directed at children.

Deletion

There is no server account to delete. See Delete your data.

Changes

If this policy changes, the new date will be on this page. The app will keep treating the vault as local-only unless a future version says otherwise before you update.
