About this app

Every document photo you send via WhatsApp can circulate for years without your knowledge or authorization.

Lacre Certo changes that.

Before sending, your image receives a visual trace with the recipient's name, the date, and a unique record. Whoever sees that document knows exactly where it came from and who it was made for. This changes the recipient's behavior—and protects you.

HOW IT WORKS

Take the photo or choose one from your gallery.

The app applies the protection automatically.

You see the result and share it.

All in less than 15 seconds.

Who it's designed for:
• You who need to send your ID, driver's license, or passport to a real estate agency, bank, or company.
• You who sell a car or product and don't want your photo in a fake ad.
• You who send a contract, resume, or proof of address and want to record who it was sent to.
• Anyone who has ever sent a document and never found out where it ended up.

SMART PROTECTION BY DESTINATION

Sending via WhatsApp? The image is sent with a complete visual trail including recipient, date, and registration ID.

Selling on a marketplace? We activate Marketplace Mode: invisible protection with prior registration, without interfering with your listing approval.

Each destination has its ideal protection. The app decides automatically.

YOUR PRIVACY IS ABSOLUTE

All processing happens on your phone.
None of your images touch our servers.
Zero tracking. Zero photo storage. Zero ads.

Scammers prefer documents without a trace.
Yours doesn't have to be that way.

Seal it before sending.
