Privacy policy

Buoyline does not collect any personal data.

What the app stores

Your answers, your progress and your practice exam results are stored only on your device. They are not sent to us or to anyone else. If you delete the app, this data is deleted with it. It can come back only from a backup of your device that you made yourself.

What the app does not do

The app has no account and no sign-in. It contains no analytics, no advertising, no tracking and no third-party code that collects data.

Purchases

Purchases are handled by Apple through the App Store. We do not receive your name, your payment details or your Apple ID. The app only asks the App Store whether this Apple ID has unlocked the full version.

Children

Because the app collects no personal data, it collects none from children either.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: [email protected].
