Health Data Notice

Your explicit consent for medical and identity details.

Last updated 20 September 2026

Draft. These documents describe what Petra does today, but they have not been reviewed by a lawyer yet, and anything in [square brackets] is still to be filled in. They will be final before Petra is released in the app stores.

Blood type, allergies, conditions, medication, pregnancy, mobility needs, height, weight and medical notes are health data. The GDPR treats health data as a special category that may only be processed with strong protection, and here only with your explicit consent.

What you agree to

Every field is optional

Only add what could help someone help you. Leaving a field empty never stops you from using Petra.

Taking your consent back

You can withdraw consent at any time: remove the details from your card, leave the groups you share them with, or delete your account. The details are then deleted from our servers straight away and from other members' phones the next time they connect.

Full details are in the Privacy Policy.
