“I hand this to every new client on day one. By the time we’re in deposition, the chain of custody is already done.”
CaseGuardian seals every photo, video, voice memo, and note the moment you capture it. Anchored to the Bitcoin blockchain. Shareable as a single link your attorney can verify in fifteen seconds. No wallet. No crypto. Just proof.
Four steps that all happen on your phone. Three of them happen before you put it back in your pocket. The fourth is what makes everything that came before it provable.
STEP 01
Photo, video, voice memo, text note, document — or a whole timestamped event with witnesses attached. Every byte is fingerprinted the instant it’s saved.
STEP 02
Encrypted at rest with AES-256. The fingerprint goes to OpenTimestamps, then to a Bitcoin block. The file stays on your device until you choose to share it.
STEP 03
One link to your attorney, the adjuster, the mediator, or whoever needs it. View-only or download. Auto-expires. Revocable. Identity-checked on both phone and email.
STEP 04
Anyone, anywhere, can paste your fingerprint into our public page and confirm the Bitcoin anchor in their browser. No app install. No account. No trust required.
The technology built to hold a custody case is the same technology a tenant uses for a deposit, a journalist uses for a source, and a military spouse uses when the heat goes out at six months pregnant.
“I hand this to every new client on day one. By the time we’re in deposition, the chain of custody is already done.”
She didn’t want to be the kind of person who needed a record. She’s the kind of person who’s glad she has one.
Eleven attempted pickups in four months. Each one stamped with the time, the place, and a photo of the door that didn’t open.
Her source said no one will believe us. The Bitcoin block from the day of the recording said otherwise.
Five days with no heat. Every landlord promise on record. A baby due in March. A husband she doesn’t know when she’ll see again.
Four months of voicemails. Photos of him at the edge of her yard. Every place he showed up, on record, before she walks into the courthouse.
She didn’t need anyone to read it. She needed somewhere it would still exist tomorrow, exactly as she wrote it tonight.
Every room of the flooded house, captured at first light. Three weeks later, the adjuster’s email on the same timeline. Both on record.
Her attorney said start documenting. She did. The Attorney Package opened in her lawyer’s browser a minute after she pressed send.
Six stops this year. Every one of them sealed before he gets home. The pattern is on his phone — and on the chain.
Medication times, fall reports, the paramedic’s name. One sealed timeline her brother — finally — could not argue with.
A dog at a roadside, an owner’s consent on the record, the responding officer’s arrival time. Sealed before she got back in the truck.
Different industries, different rooms, different reasons to hold the line. The pattern is the same: a moment that mattered, a record that holds, a person at the other end who has no choice but to take you seriously.
Every time you save a capture, CaseGuardian creates a 32-byte mathematical fingerprint of that file — called a hash — and forwards only that fingerprint to the public OpenTimestamps network, which anchors it into the Bitcoin blockchain.
Your file, your filename, your case, your identity, and your IP address are never sent. The hash is relayed through our own servers, so calendar operators see our server’s IP, never yours. The hash itself is a one-way function: it cannot be reversed into your photo, your video, your voice memo, or your document, and it reveals nothing about the underlying content.
From that moment on, anyone can prove your capture existed exactly as you recorded it, on the exact date and time you recorded it. Including a judge. Including opposing counsel. Including you.
No wallet. No purchase. No fees. No gas. No exchange account. Bitcoin is the most secure, most tamper-proof public ledger ever built — so we use it the way a courthouse uses a notary book: as a permanent, independent witness.

If you’re an attorney, this is the tool you can hand a client on day one. If you’re a client, this is the way to walk into your lawyer’s office with a sealed file instead of a shoebox.
The Attorney Package is a single, branded, indexed, hyperlinked file your attorney can drop into discovery without reformatting. Every item carries its hash, its timestamp, its witness statements, and a one-tap link to public verification. The Glossary inside the app translates legal jargon into everyday words so your client never has to interpret evidentiary law on their own.
See attorney featuresWe’re engineers. The engineering claims are mathematically real. The legal outcomes belong to the court and to your lawyer, where they should.
CaseGuardian is a record-keeping tool, not a safety device. Saving a record is not a substitute for getting to safety.
No. You don’t buy any. You don’t hold any. There’s no wallet, no fees, no exchange account. The Bitcoin blockchain is the world’s most tamper-proof public ledger, so we use it the same way a courthouse uses a notary book — as an independent, permanent witness. Your only interaction with it is that anyone can verify your captures against it later.
It proves the file existed at or before a specific Bitcoin block — an independent cryptographic timestamp, not a notarization. It does not verify anyone’s identity, authenticate who captured it, prove the contents are truthful, or guarantee admissibility in court. That’s your attorney’s job. We make the receipt. The law is your lawyer’s job.
Only what you opt in for, per item, per capture. And it never sees your name. When you flip the “Parse with AI” toggle on a bank statement or a transcript, CaseGuardian first runs an on-device pass that redacts your name, phone number, email, mailing address, and the names of the people in your life. The redacted item is then sent to our AI sub-processor, Anthropic, only for that one task — Anthropic is contractually prohibited from training on or retaining your content. AI is off by default. Your evidence never trains a model, never feeds an ad network, and never leaves your device until you personally review and approve it.
Only if you send it to them. Every share link requires both a phone number and an email to unlock — so a misplaced URL alone isn’t enough. You can also set links to view-only with watermarks, auto-expire on a schedule, or revoke them at any time.
The Bitcoin anchors don’t. They’re in the public ledger, forever, with or without us. Any file you’ve exported (or that lives in your own Dropbox or Drive backup) is still verifiable against those anchors using any OpenTimestamps verifier in the world. We’re building toward a long-term court-export archive (sealed .zip + .ots + PDF index) that works even when we no longer do.
