ProofStamp

Privacy Policy

Effective October 9, 2026

This policy covers the ProofStamp app for iPhone and iPad, made by Olympic Digital Solutions (“we”).

In short: ProofStamp collects no personal data. There are no accounts, ads, analytics or tracking. Your photos, videos, locations and projects are stored only on your device, and leave it only when you choose to share or save them.

What stays on your device

Everything you create with ProofStamp is stored in the app's private storage on your iPhone or iPad:

We have no servers that receive this information and no way to see it. If you delete the app, this data is deleted with it. Copies you saved to your Photos library or shared stay where you put them.

Permissions

You can change any of these at any time in your device's Settings.

Information that leaves your device

Street addresses

To print a street address on a photo, ProofStamp uses Apple's built-in location service to turn GPS coordinates into an address, the same service used by Apple's Camera and Maps apps. Apple's handling of these requests is covered by Apple's Privacy Policy. Turning off the address field in Stamp Style stops these lookups.

Certified timestamps

When certified timestamps are on (Settings → Proof), ProofStamp sends a fingerprint of each photo or video to an independent timestamp authority, which signs it with the current time. The fingerprint is a SHA-256 hash: a 64-character code calculated from the file. The photo or video cannot be recreated from it, and it contains no location, name or other personal information.

The authorities are Sectigo (timestamp.sectigo.com), with FreeTSA (freetsa.org) as a backup. Like any website, they can see the IP address of the device making the request. Their handling of that is governed by their own privacy policies. You can turn certified timestamps off at any time.

Sharing

When you share a photo, video, certificate or PDF report, it goes only where you send it (Mail, Messages, AirDrop, Files and so on). Photos keep their GPS position in their hidden data unless you choose Share without location data or turn on Remove GPS data from files in Settings.

What we don't do

Children

ProofStamp is suitable for all ages and collects no information from anyone, including children under 13.

Changes to this policy

If this policy changes, the new version will be posted on this page with a new effective date. Any change that affects how your data is handled will also be described in the app's update notes.
