Subprocessors

This page lists the third‑party vendors (subprocessors) we use to operate, secure, and improve Compass Calendar. Each vendor only processes data necessary for its function, under a data processing agreement and with appropriate security controls.

Current subprocessors

• Google Calendar — Calendar sync for your events.
• PostHog — Product analytics to understand feature usage, funnels, retention, and performance so we can improve the app. No third‑party ad retargeting.
• Google Cloud Platform — Infrastructure hosting for application services, storage, and networking.
• Google Analytics — Web analytics for certain website pages; helps us understand traffic and site performance.
• Kit — Email delivery for newsletters and product updates (opt‑in).
• GitHub — Source control and CI/CD for code, issues, and build pipelines.
• Supertokens — Authentication/session management to keep user sign‑ins secure.
• MongoDB — Application database for storing account data and calendar content you choose to save.
• Stripe — Payment processing for subscriptions.
