Summary: SentenMem does not collect, store, or transmit any of your personal data. Everything you do in the app stays on your device.

What we do not collect

SentenMem is built to work without collecting anything about you:

• There are no user accounts. You never sign up or log in, and we never ask for your name, email address, or phone number.
• There is no analytics, advertising, or tracking in the app, and it contains no third-party SDKs or packages.
• The app does not ask for permission to use your camera, microphone, photos, contacts, location, calendar, health data, or notifications.
• We do not run any server for the app. Studying does not send data anywhere.
• We do not use your device's advertising identifier, and we do not share any data with advertisers or data brokers, because we have no data to share.

What stays on your device

Your study progress (words learned, review schedule), statistics, achievements, and settings are stored only on your device, inside the app's private storage. They are never uploaded, and we cannot see them.

If you back up your device with iCloud or a computer, iOS may include the app's data in that backup. Those backups are created and controlled by you and Apple, not by us.

Pronunciation (text-to-speech)

Word pronunciation uses the speech voices built into iOS, which run on your device and do not need an internet connection. If you choose to download higher-quality voices, iOS does that in its own Settings, outside of the app.

In-App Purchases

SentenMem is free to download. Some word libraries are unlocked with an optional Pro subscription or a one-time purchase.

• All purchases are processed by Apple through the App Store. We never receive your name, payment details, or Apple ID information.
• The app checks your purchase status on your device using Apple's StoreKit framework.
• Apple provides us with aggregated sales and subscription reports in App Store Connect. These reports do not identify individual users.
• Apple's own privacy policy is here: https://www.apple.com/legal/privacy/
