Is Sync2Cal safe?

Sync2Cal connects via an ICS subscription URL or OAuth. It never asks for your password and never reads the events you create or your other calendars.

Yes. Sync2Cal connects to your calendar without ever asking for your password, and it never reads the events you create yourself. There are two ways your calendar can connect, and they work differently. Here is exactly what each one does.

The two ways Sync2Cal can connect

ICS subscription (the default): When you subscribe to a calendar, Sync2Cal gives you a URL. You add that URL to Google Calendar, Apple Calendar, or Outlook, and your calendar app fetches events from us on a schedule it controls. No account sign-in.

No OAuth permission requested
Sync2Cal never signs into your account
The feed is read-only on your side
You can unsubscribe any time in your calendar app

OAuth push (optional, for fast updates): You connect your Google or Microsoft account so Sync2Cal can write events into a dedicated calendar it creates for you. Updates arrive automatically, usually within minutes of the first sync.

Sync2Cal never reads the events you create or your other calendars
It only writes to the dedicated calendar it creates
We never ask for your password
You can revoke access any time

In both modes, your existing events and personal information stay private. The only thing Sync2Cal adds events to is the calendar you subscribed to.

What each connection can access

Data	ICS subscription	Google (push)	Outlook (push)
Your password	Never seen	Never seen	Never seen
The events you create	Not accessible	Not accessible	Never read
Your other calendars	Not accessible	Not accessible	Never read
The calendar Sync2Cal manages	Published via a URL	A calendar we create	A calendar we create
Your email address	Only if you signed up	Yes (sign-in)	Yes (sign-in)

Note on Google vs Outlook: with Google, Sync2Cal uses an app-created-only permission, so it technically cannot even see your other calendars. Microsoft does not offer an app-created-only option, so the Outlook permission is broader — but Sync2Cal still only ever writes to the calendar it creates and never reads your other events.

How to disconnect Sync2Cal

If you subscribed via an ICS URL: open your calendar app, find the Sync2Cal calendar under "Other calendars" (Google), "Subscriptions" (Apple), or "Internet calendars" (Outlook), and delete it.

If you used OAuth push: go to sync2cal.com/me/account, find Google Calendar or Outlook under Integrations, and click Disconnect. You can also revoke access directly:

Google: myaccount.google.com/permissions
Microsoft: account.microsoft.com/privacy/app-access

Frequently asked questions

Is Sync2Cal safe to use?⌄

Yes. Sync2Cal connects either through an ICS subscription URL your calendar app fetches on its own, or through an OAuth connection that lets it write events into a dedicated calendar it creates. It never asks for your account password and never reads the events you create yourself.

Is Sync2Cal legit?⌄

Sync2Cal is a calendar service used by tens of thousands of subscribers across Google Calendar, Apple Calendar, and Outlook. Payments are handled by Stripe, and the Google Calendar integration uses Google's restricted, app-created-only calendar permission.

Can Sync2Cal see my existing calendar events?⌄

No. Sync2Cal never reads the events you create or your other calendars. With ICS it only exposes a URL your app reads. With Google it uses an app-created-only permission that technically cannot access your other calendars. With Outlook, Microsoft only offers a broader calendar permission, but Sync2Cal only ever writes to the dedicated calendar it creates and never reads your other events.

What permissions does Sync2Cal request?⌄

Google Calendar: the calendar.app.created scope, which grants access only to calendars Sync2Cal creates. Outlook: Calendars.ReadWrite, Microsoft's standard calendar permission (Microsoft has no app-created-only option) — Sync2Cal uses it solely to write to the one calendar it creates. ICS subscriptions need no permission at all; you just add a URL.

How do I disconnect Sync2Cal from my calendar?⌄

Go to sync2cal.com/me/account, find Google Calendar or Outlook under Integrations, and click Disconnect. You can also revoke access from your Google account permissions page or Microsoft account permissions page, or by deleting the subscribed calendar in Apple Calendar.

Where is my account data stored?⌄

Account data (your email, the calendars you have synced, and your subscription plan) is stored securely. We do not sell, share, or use your account data for advertising. See our privacy policy for the full details.

Does Sync2Cal store my Google or Microsoft password?⌄

No. We never see or store your password. The OAuth flow happens entirely on Google's or Microsoft's servers; we only receive a revocable access token that we use to write events into the calendar we created.
