Privacy Policy — TNM Cancer Staging

Last updated: 12 August 2026

Introduction

This policy explains what the TNM Cancer Staging app collects, why, and what control you have over it. We collect as little as the app needs to work. By using the app you agree to this policy.

Scope

This policy covers the mobile app and the services that support it. It does not cover:

Third-party websites or services you open from links inside the app, such as PubMed
The Apple App Store and Google Play, which process purchases under their own policies
Your employer's or institution's systems

What we collect

Account details — your email address and display name when you create an account
Usage data — which screens and features are used, so we can improve the app. This is aggregated and is not used to build a profile of you
Device data — device type, operating system and app version, for diagnostics and to deliver notifications you have opted into
Saved items — favourites and preferences, so they follow you across devices

What we do not collect

We do not collect patient data. Please do not enter patient-identifiable information into the app. Staging calculations and clinical scenarios you work through are not recorded against your account.

We do not sell your data and we do not share it with advertisers.

How we use your information

To provide the app and keep you signed in across devices
To send content updates and educational notifications, if you have allowed them
To diagnose faults and improve reliability
To respond to your support requests

Content updates

Reference content in the app is written and reviewed by our clinical team. We use software tooling to help draft and cross-check that content, and a clinician reviews it before it is published to the app. Updates are delivered over the internet, so content can change without you reinstalling. This process uses no personal data.

Notifications

If you allow notifications, we store a delivery token for your device so we can send content updates and educational prompts. You can turn notifications off at any time in your device settings. Tokens are removed once they stop being valid.

Data storage and security

Data is stored with established cloud infrastructure providers, encrypted in transit and at rest. Access is limited to the people who need it to operate the service.

Most reference content is stored on your device so the app works offline. That local copy stays on your device and is removed when you uninstall.

Your rights

You can:

Access the personal data we hold about you
Correct it if it is wrong
Delete your account and its data, from within the app under Settings
Withdraw consent for notifications or analytics at any time

Children

The app is intended for healthcare professionals and students. It is not directed at children and we do not knowingly collect data from them.

Changes to this policy

If this policy changes materially we will update the date at the top of this page and, where appropriate, notify you in the app.
