Privacy policy
Short version: we don’t collect anything. The OB Wheel calculator runs entirely in your web browser. Every date you enter and every result is computed on your own device and is never sent to us or anyone else.
What we collect
No personal data and no health data. There are no accounts, no sign-up, no email capture, and no forms that transmit your inputs. We do not store your calculator inputs on any server — there is no server involved in the calculation.
Cookies and tracking
We do not set tracking cookies and do not use fingerprinting. Because no cookies are set, no cookie-consent banner is required.
Analytics
If privacy-friendly analytics are ever enabled on this site, they will be Cloudflare Web Analytics only, which is cookieless and does not collect personal data or build user profiles. Nothing else is used. If you are reading this and see no cookie banner, that is by design.
Shareable links
The calculator can optionally build a “copy link” that encodes your inputs in the URL, so you can share a result. This only happens when you press the button. If you share such a link, the dates you entered will be visible in it. Those parameters are never transmitted to us.
Your rights (GDPR / CCPA)
Because we process no personal information, there is nothing for us to sell, share, disclose, or delete on your behalf. This posture is intended to satisfy the GDPR and CCPA by design: no personal data is collected in the first place.
