Privacy and important note
No account. No ads. No subscription. BiutimiSun is an advisory app for sun habits, built to help you act more carefully.
It does not diagnose, treat or guarantee safe time in the sun, and should not replace medical advice, sunscreen instructions or common sense when UV is strong.
