  * - If [Do Not Track](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/doNotTrack) is

  * `respect_dnt` flag being passed to `posthog.init`).
  - * - If the `feature_pseudonymous_analytics_opt_in` labs flag is `true`, track pseudonomously, i.e.
  - * hash all matrix identifiers in tracking events (user IDs, room IDs etc) using SHA-256.
  - * - Otherwise, if the existing `analyticsOptIn` flag is `true`, track anonymously, i.e.
  - * redact all matrix identifiers in tracking events.
  + * - If the `feature_pseudonymous_analytics_opt_in` labs flag is `true`, track pseudonomously by maintaining
  + * a randomised analytics ID in account_data for that user (shared between devices) and sending it to posthog to
  + identify the user.
  + * - Otherwise, if the existing `analyticsOptIn` flag is `true`, track anonymously, i.e. do not identify the user
  + using any identifier that would be consistent across devices.
  * - If both flags are false or not set, events are not sent.
