Privacy Policy

This policy describes how Spacetime Ledger (the “App”) handles your information. It applies to the iOS app (iPhone and iPad).

1. Information we collect

The App does not collect any personal or other information about you.
There is no account registration, and the App never asks for your name or email.

2. Where your data is stored

Data you enter is stored only on your device (in the app’s storage).
It is never sent to any external server, including the developer’s.
On iOS, your data is kept in a file in the app (“Spacetime Ledger.json”), which you can see in the Files app under “On My iPhone”. Snapshots for rolling back and display settings such as language and color are also stored on your device.
On iOS, the app’s storage may be included in Apple’s backups if you have iCloud Backup turned on.

3. Exporting and sharing

Exporting or sharing data happens only when you do it, and you choose where it goes.
The destination’s own policy applies to the data you send there.

4. Analytics, advertising and tracking

5. Deleting your data

“Delete all data and return to a fresh state” in the app’s Settings erases your records and snapshots and resets the App (on iOS, the file in the Files app is reset as well).
Files set aside during data recovery (“Spacetime Ledger set aside …json” on iOS) are not erased by this; you can delete them in the Files app.
Deleting the app also erases your data. Any copy in your iCloud Backup can be deleted from your iCloud settings.
The developer cannot recover deleted data.

6. Changes

7. Contact

Your email address and message are used only to reply to you and are never shared with third parties.
