What cookies are
Cookies are small text files a website asks your browser to keep, so the site (or a third party) can recognise the browser later. This policy covers cookies and similar technologies — local storage, pixels, device identifiers — together, because GDPR and the ePrivacy rules treat them the same way.
Cookies currently in use
BaleMath does not set its own cookies. When you explicitly choose a measurement system or currency, BaleMath uses one first-party local-storage record, balemath.preferences.v1, so that choice can be used on other calculator pages and future visits. It contains no calculator inputs, results, identifiers, or tracking data and is never transmitted to BaleMath.
Cloudflare, Inc., which delivers and protects the site, may set strictly necessary cookies when needed for security or abuse prevention. Those cookies are not used by BaleMath for analytics, advertising, or personalisation.
If you turn analytics off, we store only the value 1 under balemath.analytics.off.v1 in this browser's local storage to remember your objection. It contains no identity, calculator data or visit history and is not transmitted. Allowing analytics again removes that record. Clearing site data also removes the choice.
Analytics without a popup
There is no consent popup for the limited cookieless statistics described in our privacy policy. You can object below at any time. This setting does not affect the calculators. Advertising, profiling or other services needing consent would require separate controls before activation.
Cookies the calculators set: none
Calculations run in the open page. BaleMath does not save calculator inputs or results in cookies or browser storage between visits. Shared plan links, calculator-transfer links, reopened-summary links and language links can contain entered values; those values may remain in browser history or hosting logs after the tab closes. See our privacy policy for details. The presentation preference described above is stored separately and is never used for analytics, fingerprinting or tracking.
No advertising or analytics cookies
Cloudflare Web Analytics uses no analytics cookies or persistent visitor identifiers. Google Analytics and advertising services such as Google AdSense are not active on BaleMath.
Managing cookies yourself
You can inspect, delete, or block cookies in your browser settings at any time. Blocking strictly necessary Cloudflare security cookies may prevent a protected request from completing.
This choice applies to new page loads on all BaleMath languages in this browser. Reload any other BaleMath tabs already open. Existing aggregate counts cannot be linked to you or removed individually.
Changes and contact
If we ever add a service that sets a non-essential cookie, this page and the privacy policy will be updated together and appropriate consent controls will be installed before it ships. Questions go to [email protected].
