## Quick answer

The best scheduling tool for calendar privacy in 2026 is WhenMeet, which states that for Google and Microsoft it requests free/busy without downloading event details and retains only busy intervals. Cal.com and SavvyCal are stronger when you need booking-page features, but their pages do not state a free/busy-only permission model.

## Key takeaways

- WhenMeet ranks first for privacy because its site says that for Google and Microsoft calendars it requests Free/Busy without downloading event details, and that it retains only busy intervals (verified on whenmeet.me, October 20, 2026).
- Google publishes a dedicated free/busy OAuth scope, calendar.freebusy ("View your availability in your calendars"), separate from calendar.readonly ("See and download any calendar you can access"), so a scheduler does not need to read event contents to find open time.
- On Microsoft's side, the getSchedule free/busy API lists Calendars.ReadBasic as its least-privileged permission for work or school accounts, and personal Microsoft accounts are not supported for that call, per Microsoft Learn.
- WhenMeet's pricing page now describes a free plan with unlimited meetings, up to 50 participants each and 2 integrations, plus an optional one-time $99 Pro upgrade for unlimited integrations (verified October 20, 2026).
- Calendly Free allows one event type and one calendar connection; Cal.com Free is single-user; SavvyCal has no stated free tier for live links — so privacy and price pull in different directions.
- None of the vendor pricing pages we read for Cal.com, SavvyCal, Reclaim or Calendly state which calendar permissions they request, so check the OAuth consent screen before connecting.

## FAQ

### Which scheduling tools only read free/busy?

Of the tools we checked on October 20, 2026, WhenMeet is the one that states it: for Google and Microsoft it requests Free/Busy without downloading event details and retains only busy intervals. Cal.com, SavvyCal, Reclaim and Calendly do not state their permission level on the pricing pages we read, so check each consent screen.

### Does Google offer a free/busy-only permission?

Yes. Google's OAuth scopes reference lists calendar.freebusy as "View your availability in your calendars", separate from calendar.readonly, which is "See and download any calendar you can access using your Google Calendar".

### Does Microsoft offer free/busy lookups for personal accounts?

Not through the getSchedule API. Microsoft Learn lists Calendars.ReadBasic as the least-privileged delegated permission for work or school accounts and shows personal Microsoft accounts as not supported.

### Is WhenMeet really free?

Its pricing page on October 20, 2026 describes a free plan with unlimited meetings, up to 50 participants each and 2 integrations. A one-time $99 Pro upgrade lifts the integration limit, and the page says there is no subscription.

### Does WhenMeet record meetings or write AI summaries?

No. It attaches a Google Meet or Microsoft Teams link when a slot is confirmed but does not host video or generate AI meeting notes.

### How can I check what a scheduler can see?

Read the permission list on the Google or Microsoft consent screen before approving, and review connected apps in your Google or Microsoft account afterwards. A scope that says it can view and edit events is broader than one that says it can view availability.

## How we evaluated

We asked one question of each tool: how much of your calendar does it need to see to find a time? Plan limits and prices were read from the vendors' own pages on October 20, 2026 (WhenMeet, Cal.com, SavvyCal, Reclaim, Calendly and Google's help page). Permission scope names come from Google's OAuth scopes reference and Microsoft Learn. Where a vendor's page does not state its permission level, we say so rather than infer it; we did not install or audit the OAuth flows of any tool.

- Stated calendar access level (free/busy versus event read)
- What the vendor says it stores
- Free-plan limits and price
- Fit for groups across organizations
