Chess Strategy Privacy Policy

Last updated: August 19, 2026

Chess Strategy: Coach & Learn is designed to work without an account and without collecting your personal data.

Data we collect

Greyscale Holding LLC does not collect, transmit, sell, or share personal data through Chess Strategy. The app has no account system, no advertising, no analytics SDK, and no tracking technology.

Data stored on your device

Your games, puzzle and course progress, coach preferences, hint balance, and app settings are stored locally on your iPhone. This information is used only to provide the app's features. It is not sent to us.

Purchases

In-app purchases are processed by Apple. The app receives purchase status from StoreKit so it can unlock what you bought, but we never receive your payment-card details. Apple's handling of purchase information is governed by Apple's privacy policy.

Children

Chess Strategy is not directed to children under 13 and we do not knowingly collect information from children.

Deleting your data

Because Chess Strategy data is stored locally, you can remove it by deleting the app from your device.

Changes to this policy

We may update this policy when the app's features change. The revised policy and its effective date will be posted at this URL.
