What we measure
Google Analytics measures normalized page types and paths, general device and browser information, approximate geography, referral sources, and a small set of standardized interactions. These include choosing navigation calls to action, selecting a Chaos File, applying map filters, viewing the result count range, opening a cited source, starting registration or a contribution, registering, signing in, and successfully submitting a contribution.
What we do not send
Analytics events do not include usernames, email addresses, account IDs, Google Analytics User-ID values, form text, map search terms, private record identifiers, or precise location coordinates. Query strings and private identifiers are removed from page addresses, and page titles are replaced with controlled page-type labels before measurement. Advertising signals and ad personalization are disabled.
Your analytics choice
Analytics storage is denied by default. If you allow analytics, Google Analytics may store first-party measurement cookies. If you decline, analytics storage remains denied; Google may still receive cookieless consent-state and generalized measurement signals for aggregate reporting and modeling. Your choice is stored only in this browser and can be changed at any time.
Retention and control
Event and user-level Analytics data is retained for no more than 14 months. Aggregated reports may remain after the underlying event-level data expires. Analytics is not linked to advertising products, and we review the retention period as the service develops.
Accounts and contributions
Account and contribution information is used to operate moderation, preserve attribution, and maintain the revision record. It is not attached to Google Analytics events. Do not submit private personal information in contribution text.
Operational safeguards
The measurement vocabulary is allowlisted in code and reviewed with each release. New events must have a documented purpose, use controlled parameters, and avoid free-form visitor input.
