Privacy Policy
Effective July 23, 2026. This policy explains what information filamentandlayer.com collects and the choices available to you.
The short version
The calculators on this site run entirely in your browser — the numbers you type in are never sent to our servers, stored, or seen by us. We don't have user accounts, sign-ups, or forms that collect personal information. The main privacy-relevant thing happening here is standard web server logs, covered below.
Information we collect
We do not require or request an account to use this site, and none of the calculator tools transmit the values you enter anywhere — all calculations happen locally in your browser using JavaScript, and the page never sends that data to a server. Like virtually every website, our hosting and CDN infrastructure automatically logs standard technical information for every visit: IP address, browser and device type, pages requested, referring page, and timestamps. These logs are used only for security, abuse prevention, and understanding aggregate traffic to the site, and are retained for a limited operational period.
Cookies and advertising
This site does not currently run any advertising or third-party tracking scripts, and does not set any cookies of its own. If that changes in the future (for example, if the site joins an ad network), this policy will be updated first to describe exactly what's added and what choices you have.
Children's privacy
This site is not directed at children under 13, and we do not knowingly collect personal information from children. Because the calculators require no sign-up and store no personal data, there is no account information to collect from anyone, including minors.
Data security
The site is served entirely over HTTPS. Because we don't collect or store personal information beyond routine server logs, there is no user database or personal data store to secure beyond our hosting provider's standard infrastructure protections.
Changes to this policy
We may update this policy as the site changes. The effective date at the top of this page will always reflect the most recent revision.
