Privacy Policy
Birthday Archive · Last updated 26 July 2026
Birthday Archive is designed to work entirely on your device. The App Store privacy label is Data Not Collected.
Data collection
We do not collect, store, sell, or share personal data. The app has no accounts, analytics, advertising, tracking SDKs, or developer-operated servers.
Data on your device
Your selected dates, local collection, preferences, and purchase entitlement cache stay on your device. You can remove them by deleting the app.
Historical database
The app ships with an offline database derived from Wikidata (CC0) and linked Wikipedia records. Looking up a date does not send the date anywhere.
Purchases
The optional one-time theme purchase is processed by Apple through StoreKit. We do not receive your payment details. Apple may process purchase information under its own privacy policy.
External links
If you choose to open a Wikidata, Wikipedia, support, or privacy link, your browser connects to that website and its policy applies. The app does not open those links automatically.
Children
The app collects no data from anyone, including children.
Changes
If the app's data practices change, this policy and the App Store privacy label will be updated before release.
