Calculator data
Height, inseam, bike type, rider weight and tire width are processed in the browser to show results. They are not saved in a BikeSize account.
Technical preferences
The site may store technical preferences such as language and theme. These preferences are used to improve navigation, not for advertising profiling by BikeSize.
URL sharing
When you use sharing features, some values can be placed in the URL so the result can be rebuilt. Anyone with that link can read those parameters.
Analytics
BikeSize pages include Google Analytics 4 and Microsoft Clarity to measure visits, technical events and aggregate usage. These services may process online identifiers, device data and navigation information according to their own policies.
Analytics events can indicate which calculator was used, the language, the resulting size and whether the inseam was estimated rather than measured. Google Analytics is used for traffic and product statistics; Microsoft Clarity is used to understand experience issues, scrolling, clicks and usability. None of this creates a BikeSize account.
Advertising and affiliate links
No advertising code such as AdSense is currently active. Before enabling ads, advertising cookies or tracked affiliate links, this notice, any cookie policy and the consent handling will be updated.
Hosting logs
The hosting/CDN provider may keep technical logs needed for security, diagnostics and page delivery.
