Essential access. Optional measurement.
Updated 20 October 2026 · The Mi Groups
Essential account cookies
mi_btc_session and mi_btc_admin authenticate member and owner sessions. Remember me extends the relevant login to 30 days; signing out revokes that session. mi_btc_enroll and mi_btc_admin_enroll support time-limited authenticator setup. These cookies are HttpOnly and Secure in production. Blocking them prevents sign-in and enrollment from working.
Browser preferences
mi-dashboard-theme stores the selected appearance; mi-motion-paused stores the animation preference. mi-privacy-choice-v1 records your optional measurement choice and its 30-day expiry. Browser/session storage may also hold temporary non-secret interface state. You can clear it using browser settings; doing so may reset preferences.
Optional campaign attribution
If a supported campaign link is used and you allow measurement, the HttpOnly mi_campaign cookie can link that visit with account creation, demo use and subscription conversion for up to 30 days. It is not required for access. No Google Analytics or Meta advertising pixel is installed by this release. Marketing management remains removed.
Changing your choice
Use Privacy choices in the footer. Essential only disables future optional measurement and asks the server to remove the current attribution cookie and visitor link. If the server cannot confirm withdrawal, the interface asks you to retry. Prior anonymous visit totals and financial/security records may remain. Clearing cookies alone does not erase account records.
Third-party content
Press images and videos are not loaded automatically. Loading an item connects your browser to its host, which can receive your IP address and device/browser information and may use its own storage. YouTube embeds use the privacy-enhanced host where supported; Vimeo and other HTTPS media have their own policies. You can leave the content unloaded.
