Privacy Policy
Marble Calm · last updated July 10, 2026
Marble Calm collects no data. None.
what the app does not do
The app has no accounts, no analytics, no advertising, no tracking, no third-party SDKs that phone home, and no server of its own. Nothing you do in the app leaves your device. Race records and settings are stored only locally and are deleted when you delete the app.
purchases
The optional Supporter Pack is processed entirely by Apple through the App Store. We never see your payment details or identity. Apple's handling of that transaction is covered by Apple's Privacy Policy.
screen recording
If you switch race recording on, the recording is made by iOS on your device and is yours — the app never uploads or accesses it beyond showing you Apple's own share screen.
changes
If this policy ever changes, the new version will appear at this address with an updated date. Since the app collects nothing, there is little to change.
