Frequently asked questions

Can I use Daj krv without an account?

Yes. Choose local mode and your profile, history, and plans remain on this device. They will not synchronize to another device and may be lost if the app is removed or the device is lost.

What happens if synchronization fails?

Your local copy remains saved. Check the internet connection, sign-in state, and try opening the app again. If the error continues, contact support with the exact message shown.

How do I delete my account and data?

Open Profile → Delete account and all data and confirm after re-authentication. Signing out alone does not delete the cloud copy.

Can I turn off anonymous statistics?

Yes. Disable the anonymous statistics switch on the initial sign-in screen or later in Profile.

Why can ITKS reserves or events be temporarily unavailable?

This public information depends on the ITKS website and your network connection. Daj krv keeps a fallback where possible, but official information may be delayed or its format may change.

Medical and official donation questions

Developer support cannot determine whether you can donate and does not replace medical advice. For official eligibility, donation events, or blood-centre contacts, use the ITKS contact page. In an emergency, contact the local emergency services.
