Your DNI, under your control

Share your ID without losing control

Ofuska is an app that stores your ID documents — ID card, passport, driving licence or health card — encrypted on your phone and creates redacted copies to share: you cover the data that isn't needed, the copy is stamped with the recipient and the date, and an invisible signature lets you find out who received it if it ever leaks. Everything happens on your device: nothing is uploaded to any server.

How your copy turns out

The same document before and after going through Ofuska. The copy has the unneeded data covered, the recipient and date tiled across the image, and an invisible signature that makes it traceable.

Examples generated with the app on a fictional document. All three outputs keep the invisible signature: it was verified by extracting it from the files.

Three steps, three taps

  1. 1

    Store

    Photograph your ID card, passport, licence or health card. It's cropped, straightened and stored encrypted (AES-256) on your phone, behind your PIN and fingerprint.

  2. 2

    Redact

    Paint or mark the areas to hide with a brush, rectangles or quick zones for your document type. Optional: black and white, and a security mosaic with the recipient and the date.

  3. 3

    Trace

    Every copy carries a unique invisible signature per recipient. If a copy shows up where it shouldn't, "Verify copy" tells you who you gave it to and when.

What Ofuska does for you

  • Everything on your phone

    Local AES-256 encryption, no servers, no accounts. Not even Ofuska can see your documents.

  • Quick zones per document

    DNI, passport or license: preset zones to cover what the process doesn't need, in one tap.

  • Security mosaic

    The recipient and the date repeated diagonally across the whole image, — the practice police forces recommend.

  • Invisible signature

    Every copy carries a hidden mark (steganography) unique to each recipient. Import a leaked copy and you'll know who received it.

  • Sending history

    Keeps the exact photos you sent to each recipient, encrypted and deletable whenever you want. And if the same recipient asks again, you resend the archived copy without redoing it.

  • Zero-knowledge backup

    Encrypted backup to your own Google Drive. Neither Google nor we can read it.

  • No ads, no tracking

    No ads, no analytics, no accounts and no data collection — not even in the free version. On Google Play it carries the "No data collected" label.

Being asked for your ID?

Hotels, landlords, utility companies and platforms ask for ID copies all the time. Here's how to share with control in each case.

Free for the essentials. Pro for everything else.

Redacting, the mosaic, black and white, the invisible signature and verification are free, and the free version carries no ads and no tracking of any kind. Pro unlocks unlimited documents and masks, automatic templates and full history for a one-time payment of €4.99. No subscriptions.

Frequently asked questions

Is it safe to send my DNI by WhatsApp or email?
Only if the copy is protected. A clean photo of your ID lets someone impersonate you if it leaks. Ofuska covers the unneeded data, stamps the copy with the recipient and the date, and adds an invisible signature so you can trace it.
Does Ofuska upload my documents to a server?
No. Everything happens on your phone: the encryption, the redaction and the marks. There is no Ofuska server. The optional backup goes to your own Google Drive, encrypted with your PIN — neither Google nor we can read it.
How much does it cost?
Ofuska is free with generous limits. Pro is a one-time payment of €4.99 — no subscriptions — and unlocks automatic templates, unlimited documents and masks, full history and copies without the app's band.
