Proof: Photo Documentation

Proof helps you create organized photo documentation records with preserved capture information and built-in integrity checks. Create records for property, vehicles, rentals, packages, before-and-after projects, personal documentation, and more. Capture photos directly in Proof and preserve their device-reported capture time, available location information, and SHA-256 cryptographic fingerprint. Capture organized records Create a record with a name, category, notes, and photos. Active records can be updated until you are ready to finalize them. Preserve capture information Proof stores photo capture times and available device-reported latitude, longitude, location accuracy, location-reading time, and location-source information. Location is optional. Verify stored data Each photo receives a SHA-256 fingerprint. Proof can verify whether stored photo bytes still match that fingerprint. Finalize important records Before finalization, Proof verifies the stored photographs. Finalizing locks the record contents and creates an additional record-level integrity fingerprint. Private iPhone and iPad synchronization Records, original photographs, metadata, and integrity information synchronize automatically through Apple CloudKit in your private iCloud account when available. Use the same iCloud account on both devices. Records remain available offline, and saved changes wait for connectivity. Concurrent changes are kept as marked separate versions so you can compare them. Export, back up, and restore Export original photo files, create PDF reports for finalized records, or create complete Proof archives containing record metadata and original photos. Restore archives after their contents pass integrity checks. Keep independent archives of important records; synchronization is not a substitute for backup. Designed for privacy No Proof account is required. Records stay locally on your device and in your private iCloud storage when synchronization is available. Proof does not send your records to the developer or include advertising or analytics. Deleting a record version removes it from synchronized lists; earlier private sync versions may remain on the device and in iCloud for conflict recovery. One-time unlock Proof offers a manually activated seven-day full-feature trial. It does not enroll you in a subscription or automatically charge you. After the trial ends, existing records remain available for viewing, integrity verification, export, backup, and deletion. Creating or modifying content requires the one-time lifetime unlock. No subscription. Proof is a documentation and record-keeping tool. Device-reported timestamps and location information are not independently verified. Integrity verification detects whether stored data matches recorded cryptographic fingerprints. It does not independently establish truth, authenticity, location correctness, or legal admissibility.
