TightnessPro

Privacy Policy

Last updated: 26 September 2026

Who we are

TightnessPro (“the app”) is published by Audit-Pro Ltd (“we”, “us”, “our”), a company registered in England and Wales under company number 16429098, registered office 20 Hepworth Gardens, Wakefield, WF1 3FH, England. For any privacy question or request, contact us at support@audit-pro.co.uk.

Summary

TightnessPro is a professional tool for volumetric gas tightness testing, direct purge reporting, and installation-volume workflows. Your test data and reports stay on your device. Your company details, test data and generated reports are not sent to Audit-Pro. The app communicates only with the relevant store and our subscription provider, RevenueCat, as needed to purchase, restore or verify your subscription (see “Subscriptions and payments” below). We do not sell your data and we do not use third-party advertising or analytics.

What information the app handles

All of the following is stored only on your device (in the app’s local database and file storage) and is not transmitted to us:

• Company / engineer details you enter for reports (e.g. company name, address, logo, engineer name).
• Test and job data you enter during tightness tests, purges, and installation-volume calculations, including any site addresses you add when exporting a report.
• Generated PDF reports, saved to your device’s storage and shared only when you choose to export or print them.
• App settings and records, including your acceptance of the in-app disclaimer and a cached timestamp of when your subscription was last verified (used to allow short-term offline access).
• Diagnostic logs generated on the device to help the app run correctly. These remain on the device.

We do not request access to your contacts, photo library, location, or microphone for the core workflow. The app uses the system file picker and print/share dialogs only when you initiate an export.

Subscriptions and payments

Access to TightnessPro requires an active subscription (with an introductory free trial). Purchases are processed entirely by Apple (App Store) or Google (Google Play) — not by us. We never see or store your payment card details. When you subscribe or restore a purchase, the app communicates with Apple’s or Google’s billing service to confirm your entitlement.

We use RevenueCat to manage and verify subscription entitlements on our behalf. When you subscribe, restore, or the app checks your access, limited purchase information — such as the store transaction/receipt and an anonymous app-user identifier generated by RevenueCat — is processed by RevenueCat to determine whether your subscription is active. RevenueCat does not receive your name or payment card details. The handling of your information by these providers is governed by their own privacy policies:

• Apple: https://www.apple.com/legal/privacy/
• Google: https://policies.google.com/privacy
• RevenueCat: https://www.revenuecat.com/privacy

How we use information

The app uses the information stored on your device only to provide its features, including producing test records and PDFs, remembering your company details and settings, and maintaining subscription access. Audit-Pro does not receive that job data. We do not profile you or use your data for marketing.

Sharing

We do not upload or share your test data, company details or generated reports with third parties. Limited subscription information is processed by Apple or Google and RevenueCat as described above. Your reports leave the device only when you choose to export, print, email or otherwise share them using your device’s own tools.

Support enquiries

If you contact us for support, we receive the information you choose to include in your message, such as your email address and details of the problem. We use it only to respond to and resolve your enquiry.

Data retention and deletion

Your data remains on your device until you delete it. You can remove it by using any in-app reset/clear function, by deleting individual exported files, or by uninstalling the app (which removes the app’s local database and settings). Exported PDFs you have already shared or saved elsewhere are outside the app’s control.

Children

TightnessPro is a professional tool intended for use by qualified gas engineers and is not directed at children.

Your rights

Depending on where you live, you may have rights to access, correct, or delete personal data we hold about you. Because we do not hold your data on a server, most data is under your direct control on your device. For any request relating to data we may hold (for example, support correspondence), contact support@audit-pro.co.uk.

Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected by updating the “Last updated” date above and, where appropriate, within the app.
