Where we rely on legitimate interests, we balance our interests against your rights and expectations and only process data that is necessary for the stated purpose.

4. Notifications and preferences

5. How we share your data

8. Children

The App is not specifically directed at children, but it may be used by people of any age. If we become aware that we have collected personal data from a child in a way that requires parental consent under UK data protection law, we will take reasonable steps to delete the data or obtain the necessary consent in line with ICO guidance.

Under the UK GDPR, you have certain rights in relation to your personal data, which may include:

You can exercise some of these rights directly in the App (for example by deleting your account) and you can also contact us using the details below. We may need to verify your identity before responding to your request.
