About this app

Your photo gets reposted, cropped, re-uploaded without credit, or scraped
into an AI dataset, and by the time you find it you are arguing about who had it first.

Priorframe answers that in advance. It signs each photo when you make it,
registering a cryptographic hash, a perceptual fingerprint and an independent
timestamp, and adding Content Credentials (C2PA). Then it watches the public web for copies, edits and suspected AI derivatives of your work. Think of it as a reverse image search that keeps running for you, plus the timestamped record to back it up.

Start with work you have already published. Priorframe looks for copies that
are already out there, not just new ones.

HOW IT WORKS
1. Capture or import a photo. Priorframe seals its hash, fingerprint and timestamp into a registry record and adds Content Credentials.
2. It checks public web sources for copies, edits and suspected AI derivatives using perceptual matching.
3. You get an alert when something surfaces, with a similarity score and a link to where it appeared.
4. When you confirm a match, Priorframe pre-fills a DMCA-style takedown notice for you to review, edit and send yourself.
5. Every registered photo gets a public verify page anyone can check, and it keeps working even when platforms strip the credentials out of your file. Share it as a link or a QR code.

Priorframe is a C2PA Conformant Generator Product (Assurance Level 1).

WHO IT IS FOR
Photographers and photojournalists who publish regularly. Creators whose
images travel faster than their credit does. Studios with an archive to
defend.

WORKS WITH
JPEG, PNG and WebP, taken in the app or imported from your camera roll. HEIC and HEIF are converted to high-quality JPEG on your device, so they work too. Camera RAW is not supported: register the JPEG you export and publish.

PLANS
Pro, $9 per month or $84 per year. For photographers who publish weekly.
1,000 photos per month, 25 pinned works watched closely, AI-derivative
detection, takedown drafts, push and email alerts.

Studio, $29 per month or $290 per year. For studios with a deep archive.
10,000 photos per month, 100 pinned works, batch protection, and API access with 50,000 calls.

Verify pages and the public verify tool are free for everyone, with no
account needed.

FREE TRIAL AND BILLING
Every plan starts with a 14-day free trial, one per customer. Cancel before
it ends and you pay nothing; otherwise billing starts on day 15 at the price
above and renews until you cancel. Manage or cancel in Google Play > Subscriptions, or in Settings in the app. Subscriptions purchased in the app
are billed through Google Play.

PRIVACY BY DESIGN
Location data is removed from every photo on your device before upload,
automatically. Images travel over encrypted connections, your data is never
sold, and there are no ad trackers or advertising SDKs. You can delete any
registered photo, or your whole account and all associated data, at any time.

WHAT PRIORFRAME DOES NOT CLAIM
A registration proves you held a particular file at a particular moment. It
does not prove authorship, and it is not a copyright registration.
Web and AI-derivative detection is a probabilistic signal, not a verdict, and
heavily transformed work can escape it.
Takedown notices are self-help templates. Priorframe is not a law firm and
this is not legal advice. For decisions that matter, consult a qualified
professional.

Prove it was yours from the start.
Sign your photos, find stolen copies online, and get a timestamped record.
