Privacy Policy
This policy explains what information may be handled when you visit MyBMI Tools, use a calculator, or contact the site administrator. The site is designed to perform calculator operations in your browser and does not require an account.
Calculator information
The calculator scripts included with this website perform their calculations in your browser. The values you enter into a calculator are used by the page to produce a result. The supplied calculator code does not intentionally transmit those entered values to a MyBMI Tools application server. Do not enter information you would not want displayed on your device, particularly on a shared or public computer.
Browser storage
The website uses your browser's local storage for convenience features. Depending on the page and actions you take, this may include your selected theme or currency, favourite calculators, recently opened calculators, and a limited list of calculator result summaries. Recent-page information and some result summaries are recorded automatically when the relevant calculator is used; they are not all saved only after a separate save action.
Local storage is kept by your browser for this website on the device and browser profile you use. It is not the same as a server-side account. You can remove it through your browser's site-data or website-storage settings. Clearing site data may also reset preferences and remove saved favourites or history.
Hosting, network logs and security
The website is intended to be delivered through a hosting and content-delivery provider, which may be Cloudflare if the site is deployed using the planned Cloudflare Pages configuration. When a browser requests a web page, the hosting, DNS, security and delivery infrastructure may process technical information such as an IP address, request time, requested URL, browser or device information, and security or diagnostic events. Such processing is governed by the provider's own terms and privacy documentation and by the services and settings actually enabled for this domain.
MyBMI Tools does not control the provider's infrastructure logs or independently determine their retention periods. Please consult Cloudflare's Privacy Policy for information about Cloudflare's processing. This reference does not mean that every Cloudflare product or optional feature is enabled on this website.
Cookies, analytics and advertising
The calculator features in this project use browser local storage for the preferences described above. The supplied project files do not include a first-party analytics platform or advertising tag. Hosting, security or third-party services may use cookies or similar technologies depending on the provider, configuration and services enabled. If analytics, advertising, embedded content, chat widgets or other third-party tools are added later, this policy must be updated before they are activated to describe the providers, purposes and available controls.
Contact enquiries
If you contact the site administrator by email, your email provider and the recipient's email provider will process the message and associated metadata. The administrator will receive the information you choose to include and may retain the correspondence as reasonably needed to respond, address a reported issue, or maintain records. Please do not include sensitive health, financial, identity or other confidential information in an enquiry.

External websites
Some pages link to external sources, public-health resources or other websites. When you follow an external link, that website's own privacy terms apply. MyBMI Tools does not control the content or data practices of external sites.
Children and sensitive information
The website is a general-purpose calculator resource and is not designed to collect personal information from children. The presence of a child-related calculator does not create an account or transmit a child's measurements through the calculator code. A parent or guardian should supervise a child's use of health-related information and consult a qualified professional when appropriate.
Your choices and applicable rights
You can avoid using optional browser features, clear this site's stored data in your browser, and choose not to send personal information by email. Depending on where you live and the laws in force, you may have additional rights concerning personal data. To raise a privacy question or request, contact the email address above. We may need enough information to understand and respond to the request; do not send identity documents unless specifically necessary and requested through an appropriate channel.
Changes to this policy
This policy should be reviewed whenever hosting, analytics, advertising, contact methods or other data practices change. The version published on this page applies from its stated update date.
