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
Google Analytics 4 loads only when Google’s consent management reports a choice compatible with analytics collection. Without a valid choice, or following rejection, its script does not start. Events may describe viewed pages, language and calculator interactions. Microsoft Clarity is paused in this configuration and its script does not load.
Cloudflare Web Analytics remains in use for technical traffic statistics provided by the hosting service. The calculators work without analytics tools.
Advertising and affiliate links
BikeSize integrates Google AdSense display ads on content pages, outside input fields and calculation results. Google and other advertising providers may use cookies and online identifiers to select and measure ads, including based on earlier visits to this or other websites.
Consent is managed through Google’s European regulations message. Manual ad units remain hidden until a valid status is available; for visitors subject to consent, starting requires permission for storage and for Google. Rejecting consent does not restrict the calculators.
When available, change your preferences with “Privacy and cookie settings” in the footer of content pages that display ads. This information and the Contact pages remain readable without consent scripts. You can also manage personalization in Google’s ad center. My Ad Center · how Google uses data on partner sites
Hosting logs
The hosting/CDN provider may keep technical logs needed for security, diagnostics and page delivery.
Contact form
The contact form lets you send a request to the person responsible for the site.
When sending is active, the optional name, email address, topic, message, language, site identifier and a technical request identifier are transmitted. The data is used to read and handle the request. There are no attachments or automated replies to visitors. A successful response means the email service accepted the message; it does not confirm delivery to the inbox.
Contact service providers
Cloudflare hosts the site and shared service and manages silent protections and technical counters. Counters record a technical identifier, UTC day and site, without email addresses, names, messages or IP addresses. The active database keeps about three days of counters; platform logs and recovery copies follow the provider’s settings. Resend forwards correspondence and Google/Gmail receives it in the responsible person’s mailbox.
Retention and site owner
Contact and privacy pages do not load analytics, session recording, ads or consent scripts. The form does not save field data in browser storage or the service worker cache. The owner’s identity and contact details, legal basis and actual correspondence retention must still be completed by the responsible person; counter retention is not email retention.
