📅

Work and personal calendars overlap, causing double-bookings

🔀

Juggling multiple scheduling tools for each side gig and role

🚫

Most scheduling services only support one account — multi-email is a paid add-on at best

✋

You end up manually copy-pasting "block events" every time

Core Features

Three mechanisms to unify your scheduling

01Unlimited

Stack multiple calendars in one view

Connect any number of Google or Microsoft accounts. We check all your events and only show truly available time.

02Privacy first

Auto-sync block events

Events are mirrored as "block events" between addresses. Original titles, attendees, and locations are never shared. Privacy first.

03Flexible

Choose organizer per booking

Send invites from your personal Gmail for casual chats, or from your work account for client meetings — your call, every time.

Use cases

Built for people who wear many hats

👔

Founders & Executives

Consolidate multiple roles (main job, advisory, side projects) into one URL. Sales, internal, 1:1s, personal — all sorted.

💼

Multi-hyphenates

Stack work and personal calendars without leaking either. Send invites from different accounts per client.

🎯

Consultants, Lawyers & Coaches

Separate consultation and discovery pages by purpose. Different durations, fees, and locations per page.

Privacy & Security

Your calendar details stay yours

OneSlate syncs events as "block events" across your calendars, but never shares original titles, attendees, or locations. Your work and personal schedules can coexist — fully private.

  • Original event titles, attendees, and locations are never synced
  • The destination calendar shows only "Blocked" — nothing more
  • You can pause or delete any sync rule, instantly
  • Two-factor authentication (TOTP) for stronger account security
  • OAuth-based integration — we never store your password
  • Full data deletion on account closure
