What are the limits of ICS Calendar Health Check?
A scoped local linter, not a full RFC 5545 certification. Reports missing UID/DTSTAMP, line folding, duplicate UIDs and parse errors. A file may be valid in other calendar clients while using features this site cannot import. Data stays in browser memory. No account connection, automatic storage, live holiday feed or background reminders. ICS exports must be imported into your own calendar app.
