Privacy Policy

Last updated August 22, 2026.

This policy describes what Vehicle Compare collects and why. It is written to match what the application actually stores, rather than to cover every possibility.

What we collect

When you create an account and subscribe, we store:

  • Your email address, from the sign-in provider you chose or the address you asked us to send a sign-in link to.
  • Billing records — a Stripe customer reference, which plan you bought, whether it is active, and when the current access period ends. We use these to decide whether to unlock the paid pages.
  • Your onboarding answers, if you complete or partly complete the setup interview: household size, preferred body styles, weekly commute mileage, maximum price, whether you prefer second-row captain’s chairs, towing needs, and any must-have features you picked. These exist purely to pre-fill your filters, and every question is skippable.

What we do not collect

  • Card numbers. Checkout happens on Stripe’s own hosted page. Full card details never reach our servers.
  • Passwords. Sign-in is by third-party provider or emailed link, so there is no password to store or leak.
  • Advertising identifiers, cross-site tracking profiles, or data sold to third parties. We do none of that.

Who processes it

  • Supabase — authentication and the application database, where the records above are stored.
  • Stripe — payment processing. Stripe holds the payment data under its own privacy policy.
  • Vercel — hosting, plus aggregate analytics and performance measurement. This is used to see which pages are slow or popular, not to profile individuals.

These providers process data on our behalf. We do not sell personal data.

Cookies and browser storage

  • Session cookies set by Supabase to keep you signed in. These are strictly necessary; the site cannot recognise you without them.
  • Local storage for interface preferences that never leave your device: your shortlist and eliminated vehicles, your compare-table column layout and grouping, and your light/dark theme choice. Clearing site data removes them.

How long we keep it

Account, billing, and preference records are kept while your account exists. Billing records may be retained longer where tax or accounting law requires it. If you ask us to delete your account, we delete your profile, preferences, and subscription records; deleting your profile cascades to that associated data.

Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise any of these, email [TODO: contact email] from the address on your account and say what you want done. We will not charge you or degrade your service for making a request.

Children

The service is intended for adults purchasing a vehicle and is not directed at children. We do not knowingly collect data from children. If you believe a child has given us personal data, contact us and we will remove it.

Changes

If this policy changes, the “last updated” date above changes with it, and we will give notice of material changes.
