optical.education is a static educational website. We've designed it to collect as little information about you as possible. This policy explains what that means.
What we don't collect
- We don't require accounts or logins.
- We don't set advertising or tracking cookies.
- Your practice-quiz answers and calculator inputs are processed in your browser and are not sent to us or saved.
What may be collected
- Privacy-first analytics. We may use Cloudflare Web Analytics, which measures aggregate page views and performance without cookies or cross-site tracking.
- Hosting logs. Our hosting and network provider (Cloudflare) processes technical data such as IP addresses and request details to deliver and secure the site.
- Email. If you email us, we receive your email address and message and use them only to respond.
Sharing
We don't sell or rent personal information. We share data only with service providers needed to run the site, or when required by law.
Children
This site is intended for adults and students preparing for professional certification. It is not directed to children under 13.
External links
We link to official websites such as ABO-NCLE, IJCAHPO, and state boards. Their privacy practices are their own.
Changes
We'll update this page if our practices change — for example, if we add accounts or purchases — and revise the effective date above.
