The only combined calendar with permission-controlled sharing
Aggregate Google, Outlook, Apple iCloud, Yahoo and more into one feed — then share it with free/busy, titles only, or full details. No other tool does both.
How it works
Connect Google, Outlook, Apple iCloud, Yahoo, GMX, WEB.DE, Fastmail, Zoho, Nextcloud, mailbox.org, Posteo, CalDAV, or any ICS feed. OAuth tokens and app-specific passwords are encrypted at rest.
Choose which calendars belong together. Webhook-driven sync means changes from any source appear in seconds — never on a polling delay.
Create different links for different people. Free/busy for casual contacts, full details for trusted collaborators. Revoke any link instantly.
Why not just share from Google or Outlook?
Features
Built around one idea: you decide exactly how much of your calendar each person sees — and no more.
Google Calendar, Outlook, Apple iCloud, Yahoo, GMX, WEB.DE, Fastmail, Zoho, Nextcloud, mailbox.org, Posteo, CalDAV, and any ICS feed. Keep work and personal schedules in one place.
Three permission levels — free/busy, titles only, or full details. Titles Only exists nowhere in Google, Outlook, or Apple's native sharing. Gate each link by email, password, or expiry.
Minimal OAuth permissions, tokens encrypted with AES-256. A full audit log of every access and permission change — because you should know exactly who has seen what.
Push notifications from Google and Outlook mean changes appear the moment they happen. No polling loops, no lag, no stale data shown to clients.
Subscribe via ICS or CalDAV from standards-compatible calendar software. Revoke the private URL anytime.
Grant selected viewers write-back access to your calendar. Ideal for PAs, EAs, and regular collaborators who need more than read access.
Privacy & security
We request minimal OAuth permissions, encrypt every token at rest with AES-256-GCM, and keep a full audit trail of who has seen what. No ads. No selling your data. Ever.
"I finally have one calendar link I can send to clients without worrying what they'll see. The permission levels are exactly what I needed."
