• Technical and usage data — IP address, device and browser information, log and error data, and feature usage. Used for security, fraud prevention, debugging, and improving the product. Legal basis: our legitimate interest in running a secure, reliable service.

Who we share it with

• Service providers acting on our instructions: cloud hosting and database, authentication, email delivery, and the AI provider that generates diagnostic output from the equipment details and symptoms you submit.
• Paddle.com, our Merchant of Record, for the sale of subscriptions, payments, subscription management, invoicing, and tax compliance.
• Professional advisers such as legal and accounting, where necessary.
• Authorities where we are legally required to disclose.

We do not sell your personal data.

How long we keep it

Account and diagnostic data are kept while your account is active and for up to 30 days after deletion so you can recover it, after which it is deleted or anonymised. Logs and security records are kept for a shorter period. Records we must retain for tax or legal reasons are kept for as long as the law requires.

Your rights

Depending on where you live, you may ask us to access, correct, delete, export, or restrict the use of your personal data, object to processing based on legitimate interests, or withdraw consent. You can also opt out of marketing at any time and complain to your local data protection authority. Email support@techdiagnose.app and we will respond within one month.

Security

We use appropriate technical and organisational measures, including encryption in transit, encrypted storage, row-level access controls that keep each account’s data separate, and least-privilege access for administrators.

International transfers

Our providers may process data outside your country, including in the United States. Where data leaves the UK or EEA we rely on appropriate safeguards such as Standard Contractual Clauses or an adequacy decision.

Cookies and local storage

We use strictly necessary cookies and browser storage to keep you signed in, remember your theme and app preferences, and cache your recent diagnoses for offline use. We do not use advertising cookies. You can clear or block this storage in your browser settings, but the Service will not work correctly without the essential items.

Changes

We will post any updates to this notice on this page with a new “last updated” date, and tell you directly if the change is significant.
