questions
Asked and answered.
Direct answers, no hedging. If yours is missing, email us.
What does signing a photo actually do?
Signing computes your photo’s cryptographic hash, its perceptual fingerprint, and an embedding, then seals them with a timestamp in the Priorframe registry. Your file is not changed in any way. The record proves this exact image, looking exactly this way, was in your hands at that moment.
Do you store my photos?
Yes. We store the image you upload plus the derived data, meaning the hash, fingerprint, and embedding, so that monitoring and verify pages work. You can delete any record or your whole account, and deletion removes images and derived data within 30 days.
What happens when you find a copy?
You get an alert with the evidence arranged: your original and the found copy side by side, the similarity score, where it appeared, and when we first saw it. From there, one tap drafts a takedown letter from your record. Nothing sends without you.
Can Priorframe really detect AI copies?
Sometimes, and we are honest about the limits. Embedding matching flags derivatives that stay close to your composition or subject, each with a similarity score. It is a probabilistic signal, not a verdict, and strongly transformed work can escape it. Nobody can honestly promise otherwise, so we do not.
Is this the same as registering copyright?
No. In most countries you own copyright automatically when you create a work. Priorframe gives you evidence of priority: an independent, timestamped record that you published first. Formal registration, where it exists, still matters for certain legal remedies. The two work well together.
What if someone signs a photo they did not create?
That is the one unforgivable act on Priorframe. You may only sign work you own or are authorized to sign. False claims of ownership are grounds for immediate termination, and the record trail makes false claimants easy to identify.
Does matching survive crops, filters, and screenshots?
That is exactly what perceptual fingerprints are for. Crops, mirrors, filters, re-encodes, and screenshots usually still match. Heavy transformations reduce confidence, and the similarity score tells you honestly how strong each match is.
Where does Priorframe scan?
We scan the web: public image hosts, the public surfaces of social platforms, marketplaces, and the open crawl. New work is scanned right away, pinned work is watched closely week by week, and the rest of your library is covered in rotation. We cannot see inside private accounts or closed apps, and we say best effort on purpose.
What does a public verify page expose?
A preview of the photo, its content hash, the signing timestamp, your public display name, and the record status. Nothing else. Not your email, not your location, and no camera metadata.
How do takedown letters work?
When a match is confirmed, Priorframe drafts a letter from your registry record, ready for the platform where the copy appeared. You review it and you send it. The letters are self-help templates, not legal advice, and Priorframe is not a law firm. For serious disputes, bring the record to a lawyer.
Where does Priorframe run?
An Android app, so you can sign photos the moment you make them, and a web app for everything else. Verify pages work in any browser with no account at all.
What does it cost?
Free covers your ten best photos, with five pinned for a close watch. Pro is $9 per month with 1,000 photos and 25 pins. Studio is $29 per month with 100 pins, batch protection, and team seats. Full details are on the pricing page.
Can I delete my data?
Yes, completely. Deleting your account removes your images, hashes, fingerprints, embeddings, and personal data within 30 days, and from backups within 90 days. Verify pages for your records are unpublished at the same time.
Do you sell my data or train AI on my photos?
No and no. Your uploads are processed only to provide the service: signing, matching, and verify pages. We do not sell personal data, and we do not use your photos to train generative models. The privacy policy spells this out.
