Privacy Policy
Effective August 31, 2026

Master Eye Correction is a visual training app. This policy explains what information is used when you train or make a purchase.

On-Device Settings
Your language and training preferences are saved locally on your device. We do not require an account, and these settings are not used to identify you.

Purchases
If you subscribe or buy lifetime access, Apple or Google processes the payment. RevenueCat helps verify purchase status and may receive purchase, app, and device identifiers needed to manage your entitlement. We never receive your full payment-card details.

What We Do Not Collect
The app does not request your name, email, contacts, precise location, photos, camera, microphone, or health data. It does not show third-party advertising.

Sharing & Retention
We do not sell personal information. Purchase information is shared only with the app stores and RevenueCat to provide and restore paid access, and is retained according to their policies and legal obligations.

Children's Privacy
The app is not designed to collect personal information from children. If you believe a child has provided personal information through a store purchase, contact the relevant app store support team.

Your Choices
You can remove locally stored settings by deleting the app. You can manage subscriptions and purchase history through your Apple or Google account.

Changes & Contact
We may update this policy when the app changes. For privacy questions, use the developer support contact shown on the App Store or Google Play listing.
