Privacy
Short version: what you type stays on your device.
The calculators run entirely in your browser. The numbers you enter are not sent to us or stored on our servers. We do not use advertising cookies.
If we add privacy-friendly analytics (page views only), this page will say which service we use. If you buy the planner, the purchase is handled by Gumroad or Etsy under their privacy policies.
