Our legal bases

Where UK data protection law applies, we generally rely on:

• Consent for precise location data when you choose to share your current location.

We may share limited data with service providers that help us run PetrolDiesel, including:

• OpenAI, to generate chat responses.

We may also share information where required by law or to protect the service against abuse, fraud, or security issues.

Retention and storage

• Preferences and saved stations stay in your browser until you clear them.
• Support emails are kept for as long as reasonably necessary to deal with the issue and keep a record of the conversation.
• Server and analytics logs are retained according to the policies of the providers we use.

Depending on where you are located, you may have rights to ask for access to your personal data, request correction or deletion, object to certain processing, or ask for restrictions on how data is used. You may also complain to the UK Information Commissioner's Office if you think your information has been handled unlawfully.
