Cookie Notice / Cookie Preferences

Necessary cookies and storage

MassMem uses localStorage, sessionStorage, Firebase Auth storage, and IndexedDB for language and sound choices, demo limits, training state, sign-in/session support, security, and the consent choice. Depending on the item, it lasts for the browser session, until the account or local data is deleted, or for 180 days for the consent choice.

The authenticated daily active-user counter is a server-side operational aggregate. It does not place an analytics cookie and is not controlled by this optional analytics preference.

Analytics/diagnostics cookies

Analytics/diagnostics are optional and off by default. With consent, Google Analytics 4 measures aggregate usage and Sentry receives technical error diagnostics. Their scripts do not load before explicit consent.

GA4 may set _ga and _ga_<container> cookies for up to 2 years. Google Ireland Limited may access analytics data. Sentry is provided by Functional Software, Inc.; diagnostic event retention must remain aligned with the period configured in the MassMem Sentry account and stated in the Privacy Policy.

Marketing tracking

MassMem currently loads no marketing tracking scripts and does not ask for advance consent for unknown future providers. If marketing technology is added, this notice and the consent version must be updated before it is enabled.

Normal outbound social share links do not load third-party tracking scripts inside MassMem.

Changing preferences

You can accept analytics/diagnostics, keep only necessary storage, or save your preference. The choice is requested again after 180 days or after a material policy change. You can reopen Cookie preferences from the footer at any time; withdrawing consent stops optional measurement and removes GA cookies accessible to MassMem.
