Propose → approve
Turn on propose mode for any calendar. A delegate’s new events and changes show up as tentative until you approve them, and nothing reaches your Google, Microsoft or Zoho calendar before you say yes.
Google, Microsoft and Zoho in one calendar
The calendar with a trusted second set of hands.
Attaché brings Google Calendar, Microsoft 365, Outlook.com and Zoho Calendar into one week view, then lets a spouse, an assistant or a caregiver help, with exactly the permissions you choose.
Available now on the web · Apps for Mac, Windows, Linux, iPhone, iPad and Android coming soon · Delegates join free
Works with the calendars you already use
- Google Calendar
- Microsoft 365
- Outlook.com
- Zoho Calendar
Your events stay in your accounts. Attaché reads and writes them there.
How delegation works
Help, without handing over your accounts
Invite someone you trust, then decide, calendar by calendar, what they can see and do. Your
accounts stay yours.
- Step 1
Connect your calendars
Connect Google, Microsoft or Zoho accounts on their own sign-in pages, then pick the calendars to bring in. They appear together in one week view.
- Step 2
Invite a delegate
Add a spouse, an assistant or a caregiver by email. They use their own Attaché account, free for delegates, and never need access to your Google, Microsoft or Zoho accounts.
- Step 3
Choose what they can do
Set permissions calendar by calendar: what they can see, whether they can add, edit or delete events and invite guests, and whether their changes need your approval.
Per-calendar permissions
Exactly what each delegate can see and do
Let your spouse run the family calendar, give your assistant titles-only access to work, and
keep your business calendar to free/busy.

Approvals and audit
You stay in charge of your calendar
Audit log with undo
Every change is recorded: who made it, what changed and when. If something isn’t right, undo it from the log.
-
Notifications
Hear about new proposals and changes as they happen.
-
Their own sign-in
Delegates sign in to Attaché as themselves, never as you.
-
Revoke at any time
Change or remove a delegate’s access whenever you like.
Security and privacy
Trust is the whole point
A delegate should only ever see and do what you’ve allowed. Attaché is built around that
rule.
-
Your accounts stay yours
Delegates never get your Google, Microsoft or Zoho passwords, or access to those accounts.
-
Encrypted token vault
Calendar access tokens are encrypted with AWS KMS envelope encryption and never sent to anyone’s browser or device.
-
Enforced on our servers
Permissions are checked server-side, so a delegate’s app never receives details you haven’t shared.
-
No ads, no selling, no AI training
Your calendar data is used only to run Attaché for you and the people you invite.
Attaché’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

What can a delegate never do?
Whatever permissions you give them, a delegate can never:
- Get into your Google, Microsoft or Zoho accounts. They sign in to Attaché as themselves; your passwords and calendar access tokens never reach them.
- Change their own access, or anyone else’s. Only you grant, change or revoke permissions.
- Approve their own proposals. On calendars in propose → approve mode, their changes wait for you.
- See what you’ve filtered out. Permissions are enforced on our servers, so their app never receives details you haven’t shared.
- Act without a record. Everything they do is written to your audit log, and you can undo it.
- Keep access after you revoke it.
Does my delegate need to pay, or have access to my accounts?
No. Delegates’ own Attaché accounts are free, and delegates never need access to your Google, Microsoft or Zoho accounts. You invite them by email and they sign in as themselves.
Which calendars does Attaché work with?
Google Calendar, Microsoft 365, Outlook.com and Zoho Calendar. Connect several accounts and see them in one week view: up to 5 connections on Free, unlimited on Pro. Your events stay in those accounts; Attaché reads and writes them there.
How does propose → approve work?
Turn it on for any calendar. When a delegate adds or changes an event there, it shows up as a tentative, dashed event for both of you, and nothing is written to your Google, Microsoft or Zoho calendar until you approve it. You can approve, edit and approve, or decline, and you’re notified when something is waiting.
Can I undo something a delegate did?
Yes. Every change is recorded in your audit log with who made it and when, and you can undo it from there. Some providers can’t bring back a deleted event itself; in that case Attaché restores it as a copy.
Is my calendar data used for advertising or AI training?
No. We use your calendar data only to run Attaché for you and the people you invite. We never sell it, never use it for advertising and never use it to train generalized AI or machine-learning models. The privacy policy has the details.
