Privacy Policy
We collect as little as possible.
Calculations
The calculator runs in your browser and does not require an account. Your inputs are not sent to us when you use the calculator pages.
Analytics
The site is instrumented to emit anonymous usage events (for example, that a calculation was completed and which material was chosen) to an in-page data layer, together with a random anonymous ID stored on your device. No external analytics provider is enabled yet, so these events are not currently sent to or stored by any third party. We will update this policy before enabling one.
Advertising and affiliates
No advertising, affiliate or referral partners are enabled. If that changes, they may use cookies under their own policies, and we will update this page first.
Your choices
You can clear site data in your browser at any time to remove the anonymous ID.
