6. Legal bases

Under UK data protection law, we rely on one or more of the following legal bases:

Contract: where processing is necessary to provide the Services, manage your account, or deliver subscription features.
Legal obligation: where processing is necessary for tax, accounting, legal, regulatory, or compliance duties.
Legitimate interests: where necessary for security, fraud prevention, service administration, infrastructure operation, record keeping, and product improvement, provided your rights do not override those interests.
Consent: where required for analytics cookies or other non-essential tracking technologies.

7. Payments and subscriptions

Web and Desktop: payments and subscriptions are handled by Stripe.

Android: payments and subscriptions are handled by Google Play.

We may receive and store limited billing metadata needed for billing history, entitlement checks, customer support, fraud prevention, and internal records, such as provider name, subscription status, product or plan identifiers, transaction references, renewal dates, cancellation status, and limited payment metadata.

8. Sharing of personal data

We share personal data only where reasonably necessary and proportionate, including with:

hosting, infrastructure, database, backup, and security providers;

support, communications, analytics, or monitoring providers where applicable;
professional advisers where required for legal, tax, or compliance reasons; and

Where personal data is transferred outside the UK, we rely on lawful transfer mechanisms where required, including adequacy regulations or other recognised safeguards.

10. Data retention

We keep personal data only for as long as reasonably necessary for the purposes described in this policy, including service delivery, support, security, fraud prevention, legal compliance, tax and accounting records, and dispute handling.

When data is no longer needed, we delete it, anonymise it, or securely isolate it where immediate deletion is not possible, such as in backups or audit archives.

11. Security

We use reasonable technical and organisational measures to protect personal data, including access controls, encrypted transport where applicable, service logging, monitoring, and security controls appropriate to the nature of the data we process.

However, no internet-based service or storage system can be guaranteed to be completely secure.
