Privacy Policy

Last updated: October 16, 2026

Sharp: Brain Training ("Sharp", "the app", "we") is built by an independent developer. This policy explains what information the app handles. In short: your training data stays on your device, we do not run user accounts, we do not show ads, and we do not sell your data.

Information stored on your device

To work, Sharp stores the following locally on your iPhone: your optional first name, the goal and preferences you choose during setup (peak time of day, daily minutes, focus areas), your exercise results, scores, streaks and daily plan, and your reminder time. This data is not sent to our servers. Deleting the app removes it.

Subscriptions and purchases

Purchases are processed by Apple. We use RevenueCat (RevenueCat, Inc.) to manage subscription status. RevenueCat receives an anonymous app user identifier, your purchase and subscription status, and basic device information needed to validate purchases. We do not receive your payment details or Apple ID. See RevenueCat's privacy policy at revenuecat.com/privacy.

Notifications

If you enable reminders, Sharp schedules local notifications on your device at the time you choose. You can turn them off at any time in iOS Settings.

What we do not do

Children

Sharp is not directed to children under 13, and we do not knowingly collect personal information from them.

Your choices

You can delete all Sharp data by deleting the app. You can cancel a subscription anytime in Settings > your name > Subscriptions on your iPhone.

Changes

If this policy changes, we will update the date above.
