Privacy Policy

Last updated: August 18, 2026

The short version

Your tax numbers are processed entirely in your own browser. When you use the free check without an account, nothing you type into the calculator is uploaded to or stored on our servers. We store information only when you explicitly choose to save it.

What we collect, and when

What we do not do

Service providers we rely on

We use a small number of infrastructure providers to run the service: Supabase (database and sign-in), Stripe (payments), and Vercel (website hosting). Each receives only the information needed to do its job.

Emails

If you save your results or create an account, we may send you the reminders you asked for (for example, year-end deadline reminders or new-tax-rules updates). Every email includes an unsubscribe link, and unsubscribing is immediate.

Your choices

You can use the free check with no account and no email. You can unsubscribe from emails at any time. You can delete saved scenarios from your account at any time, and you can contact us to request deletion of your account and all associated data.

Changes

If this policy changes, we will update this page and the date above. Material changes will be noted prominently.
