Privacy Policy
Effective: January 2026. Swim Time Converter ("we", "us") respects your privacy. This policy explains what we do and don't do with data.
01Privacy-first by design
Privacy is at the core of this site. All calculators run entirely in your browser — JavaScript on this page — and none of the times or distances you enter are transmitted anywhere. There is no database, no account system, and no backend that receives your inputs.
02Local storage
Your device keeps only the settings you choose on this site, such as your preferred course and gender, in your browser’s local storage so your tool preferences persist between visits. You can clear this at any time by clearing your browser data for this site. No personal information is stored server-side.
03Automated data we collect
Like most websites, our hosting and analytics may capture routine technical information — such as your IP address, browser type, pages visited and timestamps — in aggregate, to keep the site working, secure and fast. If we place analytics cookies, they are used to understand which tools and guides are useful, never to sell or share personal data.
04Cookies
This site aims to be cookie-light. Any cookies used are strictly for essential site function or first-party analytics. We do not run third-party advertising networks that profile you across the web.
05Third-party services
We may use standard services for hosting, performance monitoring and email correspondence. These services process the minimal data needed to provide them, under their own privacy policies. We do not sell or rent personal information to anyone.
06Your rights
Depending on where you live, you may have rights to access, correct, delete or restrict use of personal data we hold. Because this site collects almost nothing, exercising these rights is usually a matter of clearing your browser data. To request help or report a concern, contact us via the Contact page.
07Children
This site is intended for general audiences and does not knowingly collect information from children. If you believe we have inadvertently received children’s data, contact us and we will delete it.
08Changes to this policy
We may update this page as the site evolves. Material changes will be reflected here with a new effective date. Continued use of the site means you accept the current policy.
