Alternatives to Zcal
Other Scheduling vendors we measure, sorted by how much they publish that Zcal does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 19 that differ from Zcal on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Zcal has 9 gaps in what we could measure: Subprocessor list, Data location stated, Status page with history, Uptime SLA with a figure, HTTPS enforced with HSTS, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change, Named privacy contact. The column “publishes and Zcal does not” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
