Zero-knowledge architecture
Most family-safety apps can read everything you send. Some sell what they read. Many build advertising profiles around it.
Kinsight Secure™ is built on a zero-knowledge architecture. Your messages, your locations, your alerts — encrypted on your device using your family's encryption keys, before anything ever leaves your phone. Our servers route encrypted payloads they cannot decrypt.
Built so we can't see what we carry.
Passwordless authentication
No passwords. Nothing to remember, nothing to phish, nothing to lose.
You sign in with a magic link sent to your email, then confirm with your phone's biometric sensor (Face ID, fingerprint). Your encryption key is bound to your device's secure enclave (Keychain on iOS, Keystore on Android) — the key never leaves the device.
Family-mediated recovery
Lost your phone? Your family helps you back in.
When you sign in on a new device, an existing family member receives a request and approves it on their phone, with biometric attestation. No password reset. No customer-service representative with a backdoor. No recovery phrase you have to remember.
This is what makes the zero-knowledge promise honest: there isn't a backdoor — not even one we control.
The encryption story, without the jargon dump
- Each family member's device holds their own cryptographic keys. There is no shared group key sitting on a server.
- Every message is encrypted on the sender's device, per recipient, using the recipient's public key.
- Our servers see ciphertext only. They cannot decrypt it, even if compelled to try.
- Forward-only history: when a family member joins, they see events from their join timestamp forward — never retroactively.
