Privacy policy

This is a plain-English starter policy. [Owner: have a lawyer review before monetizing or launching outside the US.]

What we collect

• VINs you look up — to build the report. A VIN identifies a vehicle, not you.
• Calculator inputs (price, income, etc.) — processed in your browser; sent to our server only when you ask the AI so it can answer, and not stored.
• Account email — if you sign in, to send sign-in links and alerts you request.
• Garage — vehicles you save.
• Feedback — what you send us, plus an optional email. If you rate an AI answer, we keep that question and answer to improve the assistant.
• Product analytics — pages viewed and buttons used (via PostHog), to improve the product. No ad tracking.

Who processes it

Supabase (database and sign-in), our hosting provider, PostHog (analytics), and Google Gemini or Anthropic (AI answers and renders — your chat messages and the report are sent to generate a reply). Our AI assistant runs on Google Gemini. On its free tier, Google may use prompts to improve its services, so don't enter personal details in chat. We don't sell or share personal information for advertising.

Your choices

• Delete garage cars anytime. Email us via the Feedback button to export or delete your account.
• California residents: you have the right to know, delete and correct personal information, and to opt out of sale/sharing (we don't sell or share).
• Turn off analytics: opt out on this device (we also honor your browser's Do Not Track setting).

Kids

Throttlebook isn't for children under 13 and we don't knowingly collect their data.
