What does usage telemetry send?

Only anonymous, aggregate signals about which Cron-Sentry screens/features are opened, plus a presence heartbeat, your site’s language/locale and a timestamp. No names, emails, user accounts, site URLs, page referrer, browser/user-agent, no persistent cookies or cross-session identifiers, and none of your scheduled tasks, their arguments or query contents. Each send uses a throwaway session token that can’t be linked to a person or across time.
