Privacy policy

Calculators

Every calculator and generator on this site runs entirely in your browser. The numbers you enter are never sent to a server, stored by us, or shared with anyone. The page URL may include your inputs as query parameters so you can share or bookmark a result — that URL lives in your browser and goes only where you send it.

Launch list

Our tools include an optional email form for a launch notification list. In the current version of the site that form does not transmit your email anywhere — it is a placeholder until the list opens, and the form tells you so when you submit it. When the list does open, this policy will be updated first, emails will be used only to send what was promised, and every message will include a one-click unsubscribe.

Analytics and cookies

We may use privacy-respecting, aggregate analytics to understand which tools are useful. We do not sell personal data, and we do not run advertising trackers in the current version. If advertising is added later, this page will describe the cookies involved before they are set.

Affiliate links

Clicking a provider link takes you to that provider's website, whose privacy policy then applies. Providers may attribute a later purchase to our link using a cookie — see our affiliate disclosure.
