Privacy
This page describes what the current Dyaan build actually stores. It is a factual description of the software, not a finished legal policy — a reviewed policy is required before a public launch.
What is stored
- Your email address, display name and a bcrypt hash of your password (or your Google/GitHub subject identifier if you sign in with a provider).
- Session records: an opaque session id, the user agent string and expiry, so sessions can be revoked.
- Areas of interest you save: a name and four coordinates.
- Password reset requests: a single-use token and its expiry.
What is not stored
- No third-party analytics or advertising trackers are loaded.
- No satellite imagery or raster data is retained; reads are performed per request against public archives and cached only in memory for minutes.
- No payment details — billing is not implemented in this build.
Third parties contacted on your behalf
When you run an analysis, Dyaan's server (not your browser) requests data from NASA FIRMS, the JRC Global Surface Water archive and OpenStreetMap Nominatim. Your browser loads basemap tiles directly from Esri, OpenStreetMap and NASA GIBS, and fonts from Google Fonts.
Deletion
Deleting an account deletes its sessions, saved areas and reset tokens by cascade. Contact hello@dyaan.earth for a deletion request until the in-product control ships.
