Best Scheduling Tools That Read Only Free/Busy in 2026

WhenMeet is the strongest fit for this category because privacy is its stated design, not an add-on. The site says that for Google and Microsoft it requests Free/Busy without downloading event details, that it retains only busy intervals, and that guests see aggregated free counts only; signed-in users who look up your email see only free/busy status, and you can block viewers in Settings. Public iCloud feeds are handled differently: they are downloaded temporarily and parsed into busy intervals. The product is a group scheduler: participants at different companies are overlaid on a shared heat-map, each in their own time zone, and a confirmed slot gets an automatic Google Meet or Microsoft Teams link. It also provides personal booking links (whenmeet.me/@you), team links, HubSpot, Salesforce and Pipedrive sync, Slack, webhooks and an MCP server and API. Per its pricing page on October 20, 2026, the free plan covers unlimited meetings with up to 50 participants each and 2 integrations, and Pro is a one-time $99 upgrade for unlimited integrations. Try it at whenmeet.me.

Cal.com approaches privacy through control of the platform rather than a free/busy-only claim. Its pricing page (October 20, 2026) lists a Free plan for one user with unlimited event types and calendars, Teams at $12 per user per month billed yearly, and Organizations at $28; it offers US and EU hosting for data residency, a dedicated database on Enterprise, the option to hide the organizer's email from attendees, and private organizations whose members cannot see each other's schedules unless permitted. It links to a self-hosted option and Docker documentation. The pricing page does not say which calendar permissions the hosted service requests, so the free/busy question stays open until you read the consent screen or the source. Visit cal.com for details.

SavvyCal offers Basic at $10 per user per month and Premium at $17, both billed annually, with unlimited scheduling links and calendar connections across Google, Microsoft, iCloud and Fastmail (pricing page, October 20, 2026). Meeting polls and overlaying your calendar on other people's links work for free, but you must choose a paid plan before you can activate scheduling links for others. Its pricing page does not describe the permission level requested from calendar providers, so we cannot rank it above tools that state their model. It earns third place on breadth of supported calendars, including iCloud and Fastmail, which several rivals do not list.

Reclaim is an AI calendar-management tool rather than a pure scheduler, so it needs deeper calendar access by design — it reshuffles tasks and habits around your meetings. Its pricing page (October 20, 2026) lists a free Lite plan (one user, one-week scheduling range, one scheduling link, one calendar sync), Starter at $10 per seat per month billed yearly, Business at $15 and Enterprise at $22. It supports Google Calendar and Outlook on all plans. That depth is useful if you want automation, but it is the opposite of a minimal-access scheduler; choose it for productivity, not privacy.

Calendly remains the default booking link. Its Free plan allows one event type and one calendar connection; Standard is $10 per seat per month and Teams is $16 when billed monthly, and Enterprise starts at $15k per year (pricing page, October 20, 2026). Notetaker, a recording and transcript add-on, is offered with Standard and Teams, which matters if you want less data captured about your meetings. The pricing page does not state a free/busy-only permission model. Choose it for familiarity with outside contacts, not for minimal data access.

Google Calendar appointment schedules keep data inside the calendar you already use, so no third party reads your availability. Per Google's help page, they can be created from a personal Google Account or a Workspace account, but only from a computer browser, not the Android or iOS Calendar apps. Some features require an eligible Workspace or Google One subscription, and co-hosts cannot be added from outside your domain. The page does not describe multi-person polls, so it solves one-to-many booking rather than group scheduling across companies.
