Privacy Policy
Birthday Archive · Last updated 30 September 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, and preferences 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
Birthday Archive has no in-app purchases, subscriptions, or ads. Nothing in the app is for sale.
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.
