Privacy Policy

Last updated: 24 September 2026

The short version

PinProof does not require an internet connection or an account. The photos, video, location data and notes you capture with PinProof are stored only on your iPhone. The app does not send this data to MT AI Systems LTD, and it does not send it to any third party. There are no analytics, advertising or tracking tools built into PinProof.

What PinProof records

When you use PinProof to capture a photo or video, the app can record, alongside the image itself:

All of this is created and stored locally, in the app's storage area on your iPhone.

Where your data lives

PinProof stores everything it records on your device. Nothing is uploaded to a server operated by MT AI Systems LTD or by any other party as part of using the app. Because your data never leaves your device through PinProof, MT AI Systems LTD does not process, store or have access to it, and does not act as a data controller or data processor for it under the UK GDPR.

If you choose to save a copy of a photo or video to your iPhone's Photos app, or to share a report, ZIP file or individual image using AirDrop, WhatsApp, email or another app, that copy is then handled by that destination app or service under its own terms — from that point on, the data is outside PinProof and under your control.

If your iPhone is backed up to iCloud or to a computer using Finder, that backup may include PinProof's app data along with the rest of your device. This is part of Apple's backup service and is not something PinProof sends or controls.

Location use

PinProof uses your iPhone's location services only while the app is open and only to timestamp the photo or video you are capturing at that moment. Location is not collected in the background, and PinProof does not build a location history beyond the record attached to each capture. If GPS accuracy is low, the app tells you so on the capture; where GPS is not available at all (for example, deep indoors), you can confirm the location manually instead.

Deleting the app or your data

Because everything is stored on your device, deleting PinProof from your iPhone deletes the photos, video, notes and location data held inside the app along with it. We recommend exporting a PDF report or a ZIP of anything you need to keep before removing the app or before setting up a new phone.

Contacting us by email

If you email support@mtaisystems.com, we use the contents of your message only to answer your question or resolve your issue. We do not add your email address to a marketing list from a support enquiry.

Children

PinProof is a professional tool intended for tradespeople, inspectors and site staff, and is not directed at children.

Changes to this policy

If this policy changes, we will update the "Last updated" date above and, where the change is significant, note it in the app's release notes.
