The world's first cryptographically verified digital sanctuary for your family.
Unhackable protection that grows with your child.
We verify system health — not your family's conversations.
Legacy parental apps work by reading everything: messages, photos, locations, browsing. That isn't safety — it's surveillance, and it makes your child a target for whoever breaches the vendor next.
Haven is built the opposite way. It is anti-spyware by architecture. Haven never ingests message content. Instead, a hardened local Compliance Shield continuously checks that the protections on the device are intact and behaving, and notarizes that proof. Your child's words stay your child's.
- No message reading. Conversations, photos, and DMs are never collected or transmitted.
- Local-first. The Compliance Shield runs on the device; your data and signing keys stay on your hardware.
- Health, not content. Haven proves the guardrails are working — without becoming a window into your child's private life.
If anything changes, you know instantly.
Every safety rule and every event is cryptographically notarized into an append-only, hash-chained ledger. Altering any past record breaks the chain — so silent tampering is mathematically detectable.
Your Private Sanctuary at work.
See Haven quietly protecting your family — real integrity proofs and block sync from active devices.

Designed for the standards families deserve.
Haven is built around Safety-by-Design principles and designed to align with UK and international digital-wellness expectations for protecting children online.
Protective defaults
Privacy and child-safety are the default state, not an upsell — minimal data, local-first, transparent to the family.
Aligned with UK aims
Designed in line with the goals of the UK's online-safety and age-appropriate-design expectations for protecting minors.
Data minimisation
Engineered for COPPA and GDPR data-minimisation principles: we collect integrity proofs, not your child's content.
Haven is designed for and aligned with these frameworks. Claims describe design intent, not formal certification.
Guidance you give together — not surveillance you impose.
The healthiest digital boundaries are the ones a child understands. Haven is built to be a Digital Mentor: it makes the rules visible, the protection transparent, and the conversation shared.
- Transparent in My Portal. Everyone can see Haven is installed and exactly what it does — protect, not snoop.
- Health-positive reporting. You see healthy digital minutes and verified safety hours — not a feed of "blocked" shame.
- Grows with them. Boundaries you can ease as trust builds, all signed and accountable.
The GhostGrid advantage, adapted for the home.
Haven is built on GhostGrid — an enterprise-grade sovereign shield and its ABX Witness notarization core, battle-tested guarding autonomous systems in adversarial environments. We brought that same hardened lineage into your living room.
Sovereign by design
Your data and Ed25519 keys never leave your hardware. We hold the proof — never the contents.
Battle-tested core
The same hash-chained ledger and drift detection that audits enterprise AI fleets now watches over the family device.
GhostGrid honeypot
Decoy tripwires detect intrusion and tamper attempts the moment they happen — adapted from adversarial deployments.
Give your family a Haven.
