Privacy & Local Measurements
Your measurements stay in your browser
The calculator runs on your device. We do not send measurements to a server, put them in URLs, collect photos or create accounts. Measurements and calculated sizes are not included in analytics.
Saving is your choice
Save on this device writes the selected calculator’s measurements, units, sizing system, timestamp and method version into this browser’s local storage. Quick and detailed records are separate. The detailed record also includes the calculation pathway. Each calculator’s save/delete controls affect only its own record. We do not save measurements automatically or synchronize between devices.
Restore reads that record and recalculates it. Delete saved removes this site’s saved measurement record; it leaves the current inputs visible. Start over clears the current inputs but does not delete a saved record.
Other people using the same browser profile may access your record. Clearing browser data removes it. Private browsing and storage restrictions may prevent saving.
Optional analytics
When analytics is enabled on this website, we ask for your permission before loading Google Analytics 4 or Microsoft Clarity. Rejecting analytics does not affect the calculator. You can change your choice using Analytics settings in the footer. The choice is stored separately from your measurements in this browser. If your browser prevents storage, your choice applies only to the current page.
Google Analytics measures page visits. We exclude URL queries, fragments and referring URLs, and disable advertising storage, Google signals and advertising personalization. We do not send measurements, calculated sizes, saved records or form values as analytics events.
Microsoft Clarity helps us understand page interactions through masked session recordings and heatmaps. The main page content, including measurement fields and calculated results, is masked before collection. We do not load Clarity on URLs containing a query or fragment. Both providers may receive connection information such as your IP address and browser details, and analytics cookies are permitted only after you agree. Rejecting analytics later stops collection after a page reload and removes this website’s analytics cookies; it does not erase data already received by the providers.
Hosting and external links
Cloudflare hosts this website. Normal website requests expose information such as IP address and browser details to the hosting service; “measurements stay local” does not mean the host receives no request data.
Source links lead to third-party websites with their own privacy policies. You do not need to share your measurements with those websites to use this calculator.
Interface preferences and contact
When you change units or sizing system, we remember those interface preferences in this browser. They contain no body measurements. The footer lets you delete preferences separately; defaults apply on the next page load.
Email sent to contact@thebrasizecalculator.com is forwarded by Cloudflare Email Routing to the developer’s mailbox. Your email address and message are used to handle your inquiry. Please do not send intimate photos or body measurements; this channel handles website and privacy questions, not personal fitting consultations.
