Every serious scheduling tool now offers an auto-delete knob: 30, 60, or 90 days, or sometimes infinite. Here's how to pick the right window, why shorter is usually better, and the three operational reasons you might actually need 90 days.
The compliance floor
Both GDPR and CCPA require data retention to be proportionate to the purpose. Active scheduling needs rarely extend past 30 days after the meeting. Any retention beyond that needs an operational justification you can write down (audit, billing, tax).
30 days: the default for most freelancers
30 days is enough to resolve post-meeting questions ("what was the invitee's name again?"), handle no-shows, and reach out once if you want to follow up. After 30 days, the meeting is historical and the privacy-risk profile favors deletion.
60 days: the balance for consultants and service providers
If you bill post-meeting (hours logged into a timesheet, invoice sent 15 days after the month closes), 60 days keeps booking records available until your invoice is paid. This is the sweet spot for most freelance consultants.
90 days: the tax/audit window
If your booking tool is your primary record for billable work, 90 days lets you close a quarter before deletion. Beyond that, you should be archiving the relevant fields (invoice date, client, hours) to your accounting system, not keeping full booking records.
Infinite retention is almost never justified
The rare exception: legal matters with mandated multi-year retention. For everyone else, "we keep it forever" is a privacy-risk liability without a matching operational benefit.

Frequently Asked Questions
What retention does Cal Clear default to?
Cal Clear defaults to 90 days but lets you configure down to 30 days for all booking metadata. Calendar free/busy checks are never persisted — they happen in real-time on every request.
Will auto-delete break my calendar history?
No. Auto-delete applies to booking records in the scheduling tool, not to events in your Google Calendar. Your calendar history is preserved by Google independent of Cal Clear.
