Privacy

Your dates remain yours

Date Sparrow does not require an account, send your entries for calculation, connect to your calendar, or keep a cloud copy.

Processing

Calculations and imported lists or calendar files are handled on this device. Files are not uploaded, and links inside calendar files are never opened.

Local storage

Theme, accent, font size, favorite time zones, recently opened tools, and work calendars you choose to save may be stored in this browser. Birth dates, participant names, and event descriptions are not saved by default.

Sharing

Nothing is added to a share link automatically. Before copying a link, you can review every included detail. Shared details may remain in browser history and basic site records, so copy the result directly when it contains private information.
