The share of people in a 2025 study who could correctly identify every real and AI-generated image and video, even when warned fakes were present. Seeing is no longer proving.
iProov study, 2025
Seal it now.
Prove it later.

OpenTimestamps
What brings you here?
Every missed pickup, denied visit, and hostile exchange
Sealed before it can be disputed. Judges see evidence, not arguments. Your record is timestamped, hashed, and Bitcoin-anchored the moment you capture it.
Why authentication
Seeing is no longer proving.
September 9, 2025
The day a U.S. judge threw out a civil case after a witness video turned out to be AI-generated. Courts are now asking of every file: how do we know this is real?
Reported by NBC News, 2025
Authentication, not just documentation
A photo is a claim.
A sealed record is proof.
In the deepfake era, courts ask one question of every file: how do we know this is real? Every CaseGuardian capture answers with math. A cryptographic fingerprint, a device signature, GPS, and a Bitcoin-anchored timestamp, all fixed at the moment of capture.
Capture
Photo, video, voice memo, or note. Every byte is fingerprinted the instant it is saved.
Seal
AES-256 encrypted on your device. The SHA-256 hash is forwarded to the Bitcoin blockchain via OpenTimestamps.
Share
One link to your attorney. View-only, auto-expiring, revocable. No account required to receive.
Verify
Anyone can paste your fingerprint into our public verify page. Math, not trust. No app, no account, no fee.
Kid Calendar
Every exchange.
Every no-show. On the record.
Custody disputes are won and lost on the schedule. Kid Calendar keeps your parenting schedule, logs attempted pickups the moment they fail, and records informal changes so a verbal agreement never turns into a he-said-she-said.
- Your full custody schedule, planned exchanges in one place
- Attempted-pickup log: one tap when a handoff fails, timestamped in the moment
- Verbal agreement tracking, so informal changes are recorded, not remembered
- Sealed exports for your attorney, reviewed by you before anything is shared
The full toolkit
Built for the fight,
whatever yours is.
Attorney Package
One sealed, view-only link with every proof inline. Auto-expiring, revocable, chain-of-custody PDF included.
Patterns intelligence
Timing clusters, location correlations, and frequency shifts detected across your timeline, formatted as a court exhibit.
Encryption keys we never receive
AES-256 on your device. The key never leaves it. Your evidence is encrypted with a key we never receive. This covers your entry text and attached files. Case and entry labels, dates, and technical metadata are not yet encrypted, and extending encryption to those fields is our highest-priority engineering work.
Atomic capture metadata
Timestamp, GPS, device ID, and hash locked in simultaneously at capture. Works offline; anchoring queues until connected.
Backup to your own cloud
Export sealed records to your own Dropbox, Google Drive, or iCloud Drive. We never hold your credentials.
Opt-in AI parsing
Structured summaries with PII redaction, off by default on every item. Nothing is sent unless you turn it on, per capture.
One vault. Every fight.
Built for the moments your word
needs receipts.
Different disputes, same math. Whatever you are documenting, the seal works the same way, and it is ready before the dispute begins.
Custody
Missed pickups, denied visits
Sealed before they can be disputed.
Workplace
Before HR rewrites the story
Every incident, timestamped and hashed.
Landlord
Condition, promises, texts
Court-ready before the dispute begins.
Domestic
Your evidence, nobody else’s version
Private, sealed, with advocate pricing for survivors.
Journalism
Protect the story and the reporter
A documentation chain that answers before litigation.
Insurance
Documented before it is disputed
A record your insurer cannot redate or reinterpret.
Disaster
The before record that makes the claim
Pre-event documentation anchored before the storm hit. When insurers question prior condition, your evidence is already court-ready.
