Privacy Policy
Effective July 16, 2026
What we collect
- Account: email and authentication data, handled by Clerk (our sign-in provider).
- Racing data you enter: vehicles, tires, setups, venues, conditions, runs, and feedback.
- Billing: handled by Stripe. We never see or store your card number.
- Basic usage data (pages, errors) to keep the service working.
How we use it
To run the product: generate setup suggestions from your inputs, keep your logbook, and process subscriptions. Aggregated, de-identified setup data may be used to improve the engine's heuristics. We do not sell your personal information.
Processors
Clerk (authentication), Stripe (payments), Neon (database hosting), and Vercel (application hosting). Each processes data on our behalf under their own security programs. Data is stored in the United States.
Your choices
You can export or delete your data by contacting us. Deleting your account removes your personal data from the production database within 30 days, excluding minimal records we must keep (e.g., billing history).
