## Description

Seal any moment in time with a cryptographic proof. Perfect for move-ins, accidents, agreements, and anything else you need to document and prove.

If it happened, prove it.

Proof creates tamper-evident, timestamped records of anything you need to document. Take a photo or video, add notes, and Proof seals it with a cryptographic hash — a unique digital fingerprint that makes it virtually impossible to alter the record after the fact.

Whether you're photographing an apartment before moving in, documenting a car accident, recording an agreement, or tracking the condition of something you're lending — Proof gives you a credible, shareable record with a verifiable timestamp.

What makes Proof different
Every proof is sealed with a SHA-256 cryptographic hash computed from your photos, videos, timestamp, GPS location, and notes. If any detail changes after sealing, the hash won't match — making tampering obvious. A hash chain links each proof to the one before it, creating a lightweight audit trail across your entire vault.

Built for real situations

• Move-in and move-out apartment photos
• Car accident and property damage documentation
• Item condition records before and after lending
• Agreements and acknowledgment tracking
• Workplace incident reports
• Online marketplace sales and shipping evidence
• Generate a professional PDF export containing your photos, full metadata, GPS location, cryptographic hash, and a QR code for easy verification.
• Share via AirDrop, text, or email. 
• Request acknowledgment — recipients can confirm receipt via a secure link, and you'll receive a push notification when they do.

Your data stays on your device
No account required. No cloud sync. No tracking. Everything lives on your device unless you explicitly choose to share it.
