Oversharing by default
A normal photo reveals the document number, address, MRZ, support number, and other details even when the recipient only needs part of them.
Built for Spain-first identity privacy
Mask your DNI before you send it.
ShareDNI helps people in Spain hide sensitive fields, add a recipient-specific watermark, and export a safer PDF or image before sharing documents for rentals, check-ins, onboarding, and KYC.

Raw photo is the wrong default.
Most requests need a copy of your document, not every field printed on it.
Most DNI requests ask for a copy. Not for every detail.
Landlords, hotels, employers, academies, insurers, and identity verification flows often request a DNI image. The usual fallback is a raw photo or scan, which exposes more than many real situations require.
Selective masking
Keep the fields that must remain visible, hide the rest, and tailor the copy to the exact scenario instead of treating every request the same way.
Watermark the reason
Mark the export for the intended recipient with text like “Only for hotel check-in” or “Only for ACME KYC.”
A safer document workflow in four steps.
Import your document, hide what should stay private, add context to the copy, and export the protected version instead of the original.
1
Import your DNI
Capture both sides with camera or scanner, or bring in existing images from your library or files.
2
Mask what should stay private
Hide the DNI number, address, MRZ, support number, or any other field that is not required for the situation.
3
Add a watermark
Label the copy for a specific recipient or use case, so the intended purpose stays visible.
4
Export and share
Send a protected image or PDF instead of the raw document photo sitting in your camera roll.
Built for real DNI sharing scenarios.
The app is not trying to be a generic productivity scanner. It is for the repeated moments when someone asks for your DNI and you want a safer copy before sending it.
Landlord requests
Prepare a copy for a flat application without exposing more than necessary.
Hotel check-in
Share the document with clearer context instead of forwarding a raw gallery image.
HR onboarding
Send a protected copy when an employer or agency asks for identification documents.
Academies and services
Handle enrollment or identity checks with a document copy tailored to the request.
KYC flows
Keep a practical privacy layer when a provider requires a supporting identity document.
What makes ShareDNI different.
The product is narrow on purpose. That is what makes the message clear and the workflow understandable in a few seconds.
DNI-first
Built around Spain-specific document sharing habits instead of a broad “scan anything” pitch.
Selective, not absolute
Hide only the parts that should stay private and keep the rest readable for the intended recipient.
Watermarks with purpose
Make the copy harder to reuse out of context by tying it to a recipient or workflow.
Local-first protection
Protected documents stay in the app on your device unless you explicitly export and share them.
FAQ
The website should answer the obvious trust questions fast, because that is what determines whether someone tries the app or closes the tab.
Does ShareDNI upload my document?
ShareDNI is designed as a local-first workflow. Protected documents stay in the app on your device unless you explicitly export and share them using your device.
What can I hide?
Any area you choose, including common DNI fields such as the number, address, support number, MRZ, or name depending on the request.
Who is it for?
Anyone in Spain who is asked to send a DNI copy and wants a safer default than a raw photo or scan.
Stop sending your DNI unprotected.
