Fact Lab does not collect your data.

Fact Lab is a local iPhone and iPad app for math practice. It has no accounts, ads, analytics, tracking, subscriptions, or third-party SDKs.

Short version

Progress is stored on the device.
Fact Lab does not send practice data to Colin or to a server.
Exporting progress is user-initiated through the system share sheet.
Deleting or resetting progress happens inside the app.

Information stored on device

Fact Lab stores learner names, practice settings, session history, answers, mastery progress, and sound preferences in a local app data file. This information is used only to make practice useful for the learner using that device.

Exporting progress

The Settings screen can export progress as a JSON file. Export uses the system share sheet, so the destination is controlled by the person using the device. Fact Lab does not receive a copy of exported files.

What is not collected

Fact Lab does not collect names, contact details, identifiers, location, photos, microphone data, purchases, diagnostics, usage analytics, or advertising data. There is no account system and no server-side profile.

Deleting data

Use Settings > Reset progress to clear practice history for the active learner. You can also delete the app from the device to remove its local app data.
