How we assess privacy at Haevn

    Summary of our Data Protection Impact Assessment. Version 1, approved 16 October 2026. Next review April 2027.

    Haevn holds things that matter to families: children's days, health details, where people are, and private messages. Before any feature that touches these goes live, we assess the risks to the people involved and decide how to reduce them. This page summarises that assessment.

    What we looked at

    The whole Haevn app. We paid closer attention to five areas: children, location, health and care, co-parenting, and AI.

    What we found, and what we do about it

    Every household is separate. Your household's information can only be seen by the people in your household. The rules that enforce this run on our servers, not just on your screen.
    Children see their own world. Children have their own simple view of family life:
    • their day
    • their chores
    • family chat
    • check-ins
    They have no adverts, no strangers, no rankings and no AI. Children cannot see care, notes or co-parenting information.
    Location is off unless you turn it on. When someone shares their location, only their own family sees it. Sharing turns itself off after 12 hours, and a clear sign shows while it is on.
    Health information is optional. Medical records, allergies and care details are only used when someone chooses to add them. We ask for clear consent before medical records are used, from the person or from someone with the right to give it for them. We are extending this to every health feature.
    Carers see a limited part of the household. They do not see family chat, notes or money.
    Co-parenting records stay fair to both parents. A shared co-parenting record can only be seen by the two parents. If one parent leaves Haevn, the shared record is kept until a set date, because the other parent relies on it. The parent leaving is told this at the time.
    AI is for adults, and it runs in the EU. AI features are only for adults. They are never used on children's information, and each use is logged.
    We keep less, for less time. Anything you delete is gone for good after 30 days. Location is cleared when sharing ends.
    Your data is yours. You can export everything Haevn holds about you, or delete your account, from inside the app.

    Where your data lives

    Your family's data is stored in London, and all AI processing happens in the EU. Some trusted providers handle payments, email, error reports and network security, and a few of them are outside the UK. Where they are, legal safeguards are in place.

    What happens next

    We review this assessment every six months, and before any new feature that affects children, carers, health, location or chat goes live. Our current plans:

    • a privacy notice written for children, with a version for each age group
    • a simple way to raise a data protection complaint
    • giving children more control over their own location sharing
