Privacy Policy

• Screen Time data. Swescroll uses Apple’s Family Controls and Screen Time frameworks to lock the apps you choose and measure your earned app time. Apple designed these frameworks so that this information is processed on your device. Swescroll never sees, stores, or transmits which apps you use, how long you use them, or which apps you have locked.
• Your learning data. Your vocabulary progress, spaced-repetition schedule, streaks, goals, and settings are stored on your device (and in your device backups). We have no server and no copy.
• Your name. If you enter a name during setup it is used only to personalize on-screen text and never leaves the device.

We use PostHog (hosted in the EU) to understand how the app is used so we can improve it. This includes events such as “onboarding step viewed”, “card answered (correct/incorrect)”, “level cleared”, or “trial started”, associated with a randomly generated anonymous identifier. These events never include your name, your answers, which apps you lock, or any Screen Time information. They are not used for advertising and are not shared with data brokers. They are not linked to your identity — we couldn’t link them if we wanted to, because we don’t know who you are.

Two features send us something you wrote or chose, and both are entirely optional — the app works exactly the same if you never use them:

• Send feedback (Settings → About). The message you write is sent to us through PostHog so we can read it and act on it. The email field is optional: if you fill it in, we receive that address and use it only to reply to you. If you leave it empty, your feedback stays anonymous like everything else.
• Reporting a flashcard. If you flag a card as wrong or confusing, we receive which card it was and which reason you tapped (for example “translation is wrong”). There is no free-text field, and nothing about you is attached.

Subscriptions are processed entirely by Apple. We do not receive or store your payment details. Our anonymous statistics record that a purchase happened (e.g. “trial started”), not who made it.

Study reminders and trial reminders are local notifications scheduled on your device. No notification data is sent anywhere.

Anonymous analytics events are retained in PostHog and cannot be traced back to you. Feedback you send is kept for as long as it is useful for improving the app; if you gave us an email address, tell us and we’ll delete both it and your message. Everything else lives on your device — deleting the app deletes it. Under GDPR you have rights of access, rectification and erasure; for anything related to this policy, contact us at info@tinywave.io.

We’ll update this page if our practices change, and note the date above.
