Why I built FamilyNav

I kept seeing the same quiet failure play out in courtrooms.

Not because parents were lying
but because truth without structure is easy to dismiss.

Attorneys would say, “My client was there.”
Judges would ask, “Can you prove it?”

And too often, the answer depended on memory, screenshots, or trust — none of which courts are designed to rely on.

FamilyNav 2.0 exists to reduce that friction.

It transforms your existing Google Maps Timeline into verifiable, court-ready documentation, designed to stand on its own — without interpretation, persuasion, or narrative spin.

Because in high-conflict or high-stakes situations, clarity isn’t just helpful.
It’s stabilizing.

What makes this different

FamilyNav doesn’t ask courts to believe you.

Every report is:

  • Cryptographically signed (Ed25519)

  • Paired with a QR code that allows instant verification

  • Tamper-evident by design — no login, no account, no gatekeeping

Anyone — a judge, attorney, or mediator — can independently confirm that the data hasn’t been altered.

No persuasion required.
No escalation needed.

What we’re not

We’re not another co-parenting messaging app.

We don’t analyze tone.
We don’t score behavior.
We don’t amplify conflict.

We prove where you were, not what you said.

What’s new in 2.0

  • Cryptographic signatures on all reports (including free tier)

  • Public transparency log with GitHub audit trail

  • Attorney Portal for secure evidence sharing

  • Compliance Pattern Analysis aligned to family-court standards

  • Video facilitation with neutral facilitators (coming soon)

FamilyNav is built for people navigating systems that weren’t designed with emotional safety in mind.

If this resonates, try the live demo — no signup required.
I’d genuinely love your feedback.

FamilyNav 2.0 is already doing the hard part (Ed25519 signatures + QR verification) to make location documentation court-usable. One concrete next step that could strengthen your “tamper-proof” claim without exposing sensitive data is anchoring only report hashes (or a daily Merkle root) to a public chain, so attorneys/judges can independently verify existence and integrity. A second area is an append-only chain-of-custody log for when evidence is created/shared/accessed, which can reduce disputes during discovery. Happy to chat more :)

@mooniemama 

Thanks so much for the thoughtful feedback! 🙌

Great news, we've actually built both of these already:

Public chain anchoring: We use a 3-layer approach:

  1. Ed25519 signatures on every report

  2. Merkle roots are published to a public GitHub transparency log every 10 minutes (anyone can audit)

  3. Individual report hashes anchored to Bitcoin via OpenTimestamps for decentralized proof-of-existence

You can see the public transparency log at familynav.app/transparency no login required.

Append-only chain-of-custody log: Every report creation, share, and access is logged immutably. Messages even use hash chaining (each message references the previous hash), so tampering breaks the chain. We also use cryptographic "tombstones" for deletions; the hash stays in the chain even when content is removed.

Would love to discuss the technical details or get your feedback on the implementation! Feel free to DM or check out the verification page linked above.
