ARCANA Privacy Policy

Effective August 13, 2026

The short version

ARCANA collects nothing. There are no accounts, no analytics, no advertising, no tracking, and no servers. Nothing you do in the app ever leaves your device.

Data we collect

None. The apps (ARCANA: Strings, ARCANA: Drums, ARCANA: Keys) do not collect, store, transmit, or share any personal data or usage data whatsoever.

Microphone

ARCANA: Strings requests microphone access only while the tuner screen is open, to detect the pitch of your instrument. Audio is processed in real time on your device and is never recorded, stored, or transmitted. Closing the tuner releases the microphone.

Local storage

Your settings (tempo, practice mode, sound, and similar preferences) and daily practice-window usage are saved only in the app's local storage on your device. Deleting the app deletes this data. We have no access to it.

Purchases

Any purchase is processed entirely by Apple's App Store or Google Play. We do not receive or store your payment details or identity.

Children

ARCANA collects no data from anyone, including children.

Changes

If this policy ever changes, the new version will be posted at this address with a new effective date.
