This page covers yozatapps.com. Each app has its own privacy policy, linked from its App Store listing and from its settings screen.
The site is static. It sets no cookies, runs no analytics and loads nothing from a third party — the app icons are served from this domain rather than from Apple.
No app requires an account. Progress stays on the device. Apps that collect anything collect pseudonymous usage counts to see which features are used, never content you type and never an advertising identifier. No app tracks you across other apps or websites.
