Free pages: no account needed. We use Google Analytics (GA4) for aggregate traffic measurement — page views, referrers, and device class. No advertising features are enabled, and we don't sell personal data.
API accounts: your email and (optional) company name, and API usage logs — which endpoints you call, when, and the response status — to run the service and enforce rate limits.
What we don't do
We don't sell your data, we don't run third-party ad networks, and we don't build profiles of the parents and students who read the calendar pages.
