Privacy Notice

How Hayatuk handles your personal and sensitive data.

Hayatuk handles personal and sensitive data (contact details, blood type, and location). This notice describes how the app treats that data. Organizations that deploy Hayatuk are responsible for their own privacy policy and for the behavior of their backend.

What we collect and why

Data	Why	Notes
Name, email, phone	Account, and letting a requester and donor coordinate	Phone is shown to the other party only after a request is accepted
Blood type	Matching donors to requests	Health-related data
Approximate location	Finding nearby requests and showing them on the map	Coarsened before leaving the device (see below)
Push (FCM) token	Notifying you about relevant requests

Location privacy

Your device’s exact GPS coordinate is never sent to the server. Before any network call, coordinates are snapped to a coarse grid, so the backend only ever stores an approximate area, not a precise position. The exact coordinate is used only locally, to center the map. Location permission is requested at the point of use, and the app works even if it is denied — you simply won’t see nearby results.

Data sharing

The app talks only to its backend and to Firebase (for push notifications). It contains no third-party analytics or advertising SDKs. A requester’s and an accepting donor’s phone numbers are exchanged only after an explicit acceptance, so they can coordinate the donation.

Your control

You can disable donor mode at any time to stop receiving requests, and you can delete your account and data at any time. See Delete your account.
