Privacy policy
Last updated: May 18, 2026
What we collect
Nothing personal. We use Cloudflare Web Analytics, which counts page views and basic device and browser information without cookies or tracking pixels. We don't know who you are. We don't follow you across the web.
What we don't do
No personal accounts. No newsletter signups. No email collection. No cookies that track you. No data sold to anyone, ever. No retargeting ads.
How calculators work
Everything you enter into our calculators — weight, height, age, and so on — is processed in your browser only. Your inputs never leave your device. We don't store, transmit, or have any access to your numbers.
Future advertising
When we add display advertising (eventually, to keep CalcForge free), we'll use privacy-respecting ad networks that don't track users across sites. We'll update this page when that happens.
Third-party services
We use Cloudflare for hosting, DNS, and CDN. Their privacy practices apply when you visit our site — the request hits their infrastructure before reaching ours. See Cloudflare's privacy policy for their specifics.
Changes to this policy
If we make changes, we'll update the date at the top. Substantial changes will be noted briefly.
Contact
Questions or concerns? We'll add a contact address here when one is ready.
