Benefits of OPEN CIRCLE Email & Calendar

Independence from hyperscalers

No ties to Microsoft, Google or other providers. You remain in control.

No lock-in

You can switch to a different groupware platform or host it yourself at any time, without losing any data or facing any restrictions.

Full control over your data

Emails, calendars and contacts remain in the Swiss Business Cloud. The data is hosted in Switzerland and data protection is governed by Swiss data protection laws (no Cloud Act, GDPR-compliant).

No kill switch

No one can block external access to or use of your data.

Fully compatible with Microsoft Outlook

Employees can continue to use Microsoft Outlook and do not have to do without the familiar interface and functions they are used to. The EAS and EWS protocols are available.

Open source & transparent

The code is open-source, audited and customisable. Security vulnerabilities are easier for the developer community to identify.
