Free, by design
Your inputs, your device

A calculator, not a health profile.

You can use StrideCalc without submitting your body measurements to a StrideCalc database.

Calculator inputs

Weight, dimensions, age and activity inputs are processed in the page in your browser. This version does not send them to a StrideCalc server, put them in page URLs or store them in local storage. Reloading the page resets the example values.

Site and hosting requests

Opening the site still sends normal web requests to the hosting provider. Those requests may include technical information such as your IP address, browser details and requested page. Hosting access controls, where enabled, may also use their own authentication information and cookies. These are separate from calculator inputs.

Browser state and cookies

The menu state lasts only while the current page is open. The application does not store that preference in a cookie. This version includes no advertising code, analytics tags, email subscription form or StrideCalc account system.

Optional browser assistant support

In a browser that supports website tools for assistants, you may ask an assistant to populate the calculator. That action uses the same local calculation. Information you choose to share with your assistant is also subject to that assistant provider’s policies.

External references

Source links lead to other websites, which have their own privacy practices. Following one of these links does not attach your calculator inputs to the link.

Changes

If advertising, analytics, saved profiles or other data collection are introduced, this information and the relevant controls must be updated before those features are enabled.
