Haevn was built UK-first, GDPR-native, and to the ICO Children's Code from the floor up. Co-parenting is not a separate product from the family operating system; the same one subscription covers a family that is together, separating, separated, blended, or any combination across the years.
The architectural choice that matters most for separated families is one subscription per family, not per parent. Each parent keeps their own Haevn home. You link the two homes for Co-Parenting by invitation. Only the Co-Parenting space is shared, and either parent can end the link. The cost is £6.99 a month, or £69.99 a year.
The co-parenting features are deliberately built for the mid-conflict middle: append-only Family Chat with timestamps and integrity hashes, a shared expense ledger with arbitrary split, a Custody Handover Log, and the wider household surfaces (calendar, lists, budget, home admin) that a separated family still needs alongside the co-parenting workflow.
Haevn is honest about its limits. It is not legal evidence by default. It is not a substitute for mediation or a parenting plan. It is not the right primary fit for active high-conflict court cases. For those, a dedicated record-keeping tool may suit better, and Haevn can run alongside as the wider household admin layer.
