Stet: Document & Photo Proof

About this app

Never get stuck in a "he-said, she-said" situation again. Whether it is a signed lease, a notarized PDF, or photos of your apartment on move-out day, stet helps you create proof that your files were not changed after you sealed them. In Latin, stet means "let it stand." With stet, you can lock in the state of a document, photo, or video and verify it later with confidence. PRIVACY FIRST: WE NEVER SEE YOUR FILES Your privacy is the foundation of stet. Your documents and photos never leave your device. stet does not upload your files to a server. It only uses a unique digital fingerprint to create proof, so your data stays private. HOW IT WORKS 1.) Seal: Select any file, photo, or video. stet creates a unique digital fingerprint on your device. 2.) Timestamp: stet records proof of when the file was sealed and can anchor that proof to a permanent decentralized record. 3.) Certify: Receive a Certificate of Authenticity you can store, share, and verify later. USE STET FOR • Real Estate: Help protect your security deposit with sealed move-in and move-out photos. • Legal and Business: Help show that a signed contract or scanned PDF was not changed afterward. • Insurance: Keep a tamper-evident record of damage photos and claim files. • Finances: Preserve invoices, receipts, and trust or estate documents. • Creative Work: Create verifiable proof for original work before sharing it. WHY CHOOSE STET? Files can be edited, photos can be altered, and metadata can be unreliable. stet helps you create a tamper-evident record so you can later verify that a file still matches the sealed version. Stop worrying about "what if." Seal it with stet and let it stand.

• Made it even easier to verify a stet document on the go.
