The short version
We do not require accounts, do not ask for health information, and do not sell personal data. The calculators run entirely in your browser; the numbers you type are never sent to us.
What we collect
- Server logs. Standard web-server logs (IP address, user agent, pages requested, timestamps) retained for security and aggregate traffic measurement.
- Email you send us. If you contact us, we keep the correspondence to respond and to maintain the corrections log. Do not send us medical information.
- Analytics. If we use analytics, it is privacy-preserving and aggregate; we do not use it to identify individuals. Any change to this will be described here.
What we do not collect
Health information. Account credentials. Payment information (we sell nothing). Data typed into calculators, which is processed locally in your browser and discarded when you leave the page.
Affiliate links
When you click a provider link, the provider and its affiliate network may set cookies or record the referral so that a commission can be attributed. Their handling of your data is governed by their privacy policies, which you should read before providing any personal or health information to a provider.
Cookies
The Site itself does not set tracking cookies. Third-party fonts may be loaded from a content delivery network, which receives your IP address to serve the file.
Your rights
Depending on where you live you may have rights to access, correct or delete personal data we hold. Email [email protected]. We will respond within 30 days.
Children
The Site is not directed to children under 18 and we do not knowingly collect information from them.
