Protect sensitive documents before you share them. 
DocMark ID lets you add a personalized watermark and date to passports, ID cards, driving licences, contracts, bank statements, payslips, invoices and other confidential files before sending them to a company or institution. If that copy is ever leaked in a data breach, the watermark makes it much harder to reuse outside its intended purpose. The reality of sharing data
Companies and online services routinely ask for copies of personal documents. Once you send a file, you often lose visibility over how it’s stored or protected. When systems are compromised, raw documents can be exposed and misused. How DocMark ID helps
DocMark ID creates a recipient‑specific version of your document before you send it. Add the company name and date, apply a clear, repeated watermark, and export a safer copy intended only for that request. Key features * Smart watermarking: add recipient name, purpose and the current date. * Universal support: passports, IDs, licences, contracts, payslips, invoices, bank statements, and more. * Flexible import: take a secure photo, choose from Photos, or import from Files/iCloud Drive. * Local processing: watermarking happens on your device — no uploads, no cloud processing. * Share with confidence: export or share the protected version directly. Your documents, your control.
Sharing confidential files shouldn’t mean giving up peace of mind. Use DocMark ID to add context directly onto the copy you send, so your documents remain tied to their intended use. Download DocMark ID and protect the documents you share.

About

Dokus

Dokus is the wallet for the documents you cannot be caught without. Passport, ID card, driver's license, student card and more, in one place, behind Face ID. These are your own copies, photos or PDFs. Dokus is not an official ID and never replaces the document itself. ON EVERY DEVICE Your wallet stays in step across the iPhones, iPads and Macs signed in to your Apple Account, through your own iCloud. Nothing is trapped on one device, and nothing passes through us. PROTECTED WHEN YOU SHARE Hotels, car rentals and booking desks ask for a copy all the time. Stamp yours with who it is for and when, so it cannot be quietly reused. Your original never changes. BEFORE IT EXPIRES Give a document its validity date and Dokus warns you in time to renew, instead of finding out at the counter. WHEN NOTHING ELSE WORKS Airplane mode, no signal, another country. Your documents open anyway, because they live on your iPhone. Reach them from the Lock Screen or Control Center. NATIVE FOR iOS AND macOS Native, fast and at home on iOS, down to the last detail. No web views, no clutter, nothing to learn. PRIVATE, AS A MATTER OF COURSE No account, no ads, no trackers. We never receive, store or analyze your documents. Dokus Plus is an optional one-time purchase, yours forever: unlimited documents, validity dates with reminders, watermarked copies for safe sharing, image to PDF conversion, and file compression. Everything else is free, including iCloud sync and the built-in scanner. Your documents. In your pocket. Encrypted.
