Privacy Policy

Short version

Pink Stack does not collect, store, or transmit any personal data to us. Reminders you declare are written into Apple Reminders (Apple's system app), where they sync via iCloud the same way any other reminder does. Pink Stack only touches reminders it created itself, never your other reminders. There are no accounts, no analytics, and no third-party SDKs that contact a server.

Who we are

Pink Stack is published by Danielius Studio LLC, a Wyoming limited liability company at 30 N Gould St, Suite #5280, Sheridan, WY 82801, USA (“we”, “us”).

Apple Reminders integration

Pink Stack uses Apple's EventKit framework to write to a calendar named Pink Stack in your Reminders database. Three reminders are created per stack. We save each reminder's calendarItemIdentifier so we can sync done-state both ways. We do NOT read your other reminders, do NOT enumerate calendars beyond our own, and do NOT access Calendar events.

When you mark a reminder done in Pink Stack, we toggle the completion flag on that specific reminder in Apple Reminders. When you mark it done in Apple Reminders, Pink Stack reads the updated state from the same reminder when you re-open the app. iCloud sync is handled entirely by Apple.

Data we do NOT collect

What stays on your device

In-app purchases

If you subscribe (Monthly, Annual) or buy the Lifetime unlock, that transaction is handled by Apple's StoreKit. Apple shares only the receipt with the app so we can verify your entitlement. We never see your card number or billing address.

Family Sharing

Pink Stack Pro purchases are Family-Shareable through Apple's standard Family Sharing mechanism.

Children

Pink Stack is rated 4+ in the App Store. Because the app collects no data at all, it complies with COPPA and similar children's-privacy regulations by design.

Your rights

Because Pink Stack does not collect data, there is nothing for us to export, correct, or delete. To remove all on-device state, delete the app (which leaves the reminders it created in your Apple Reminders unless you also delete the “Pink Stack” list).

For questions, write to privacy@danielius.studio.

Changes

If we ever introduce a feature that involves any data leaving the device to a server we operate, this page will be updated.
