Data minimization is a core privacy principle: collect only what you need, keep it only as long as you need it. A scheduling app with minimal data collection applies that to booking — and dramatically reduces the risk of exposure. Cal Clear is built around it.
The Minimization Standard
Ask of any field: is this strictly necessary to complete a booking and send confirmations? If not, don't collect it. Cal Clear passes everything through that filter, which is why it gathers so little.
Exactly What's Collected
- From you (host): free/busy calendar status — never event contents
- Per booking: invitee name, email, chosen time
- Nothing else: no behavioral analytics, no device fingerprints, no ad-profile data
Retention: Kept Short by Default
Minimization applies to time as well as fields. Cal Clear's auto-delete controls purge old booking records so data doesn't accumulate indefinitely. The smaller the standing dataset, the smaller the breach blast radius. See scheduling data breach risk.
Why Minimal Beats "Secure"
Encryption and access controls matter, but the safest record is the one that was never collected. Minimization is privacy at the source, not just protection after the fact. See no unnecessary data collection.
