This policy explains the necessary and optional storage technologies used by BMLabs Mathematics and how visitors can control Google Analytics and advertising preferences.
Updated 15 July 2026
Section 01
Necessary browser storage remembers essential display choices such as the selected light or dark theme and the visitor's privacy preference. These functions support the operation of the website and do not require optional analytics or advertising consent.
Section 02
Google Analytics is optional. It is loaded only after a visitor grants analytics permission through the privacy choices panel. The resulting aggregate information helps us understand which learning pages are useful and where the interface can be improved.
Section 03
Google AdSense and advertising-related storage are optional. The AdSense script remains disabled until advertising permission is granted and is also disabled on staging environments. Advertising helps support free public access to the academic repository.
Section 04
After making a selection, use the Privacy choices button displayed near the lower edge of the website to reopen the panel. You may accept or reject analytics and advertising independently at any time.
