Privacy
Short version: your income numbers never leave your browser. We only hold an email address if you hand one over for the deadline reminders.
What we collect
- Calculator inputs - never transmitted. They are computed locally and kept in the page URL so you can bookmark or share a scenario. That means a shared link contains your numbers, so do not post one publicly.
- Email address - only if you submit the reminder form, used only to send the four quarterly deadline emails.
- Analytics - aggregate page views, no cross-site profiles.
Advertising and affiliate links
This site is supported by advertising and by affiliate links to tax software and accounting services. Affiliate links are marked and are not part of the calculators - they never change a result. Ad partners may set cookies; where required by law you will be asked for consent before non-essential cookies are set, and you can decline and still use every calculator.
Your choices
- Clear your browser storage to remove locally saved state.
- Unsubscribe from any email in one click.
- Block advertising cookies at browser level; the calculators keep working.
