Calculator xy Privacy Policy

What we store on your device

Your calculation history and preferences (theme, angle unit, number format) are stored locally on your device. This data never leaves your device unless you enable cloud sync below.

Cloud account and history sync — optional, Pro feature

If the developer has configured cloud sync for this build and you choose to create an account, your email address and calculation history are stored in a Supabase project operated for this app, protected so that only your signed-in account can read or write your own history rows. If cloud sync is not configured for this build, this feature is hidden and no account data is collected.

Subscriptions

If in-app purchases are enabled for this build, purchase and entitlement status is processed by RevenueCat and the applicable app store (Apple/Google). We do not receive your payment details.

Data deletion

You can clear local history at any time from within the app. If you created a cloud account, contact the developer to request deletion of your account and synced history.

Children

The app is not directed at children and does not knowingly collect data from children.

Contact

Questions about this policy can be sent to the developer contact listed on the app's store listing.

Provided as-is

Calculations and graphs are provided for educational and productivity purposes. Always verify results independently, especially for graded work, exams, or safety-critical use.

Subscriptions

Where offered, subscriptions renew automatically until cancelled through your app store account settings, per the applicable store's terms.

No warranty

To the maximum extent permitted by law, the app is provided without warranties of any kind, and the developer is not liable for damages arising from use of the app, including reliance on calculation or graphing results.

Changes

These terms may be updated from time to time; continued use after an update constitutes acceptance of the revised terms.
