Frequently asked questions

The service

What does Cronofy do?

Cronofy provides real-time and secure two-way calendar-sync so that software and applications can connect with their users’ calendars. No matter what calendar service they use.

How does Cronofy work?

Cronofy allows developers to build software that connects with multiple calendar services while working with just one API. This saves them time, saves businesses money, and makes the ongoing maintenance of building calendar connectivity easier for everyone.

Do I need to connect to different calendar services?

No, Cronofy supports applications that sit between the various calendar services and provides access to all or some of the five major calendar services that we connect to.

Which calendar services does Cronofy support?

Apple, Google, Microsoft Exchange (including on-premise), Microsoft Office 365, and Microsoft Outlook.com.

Do I need to enable each calendar service?

No. Cronofy’s APIs automatically give you access to the five calendar services.

What is required to integrate my application with Cronofy?

You set the rules and must provide the UI for your application. You need to integrate our authentication process and use our API to retrieve calendar data. Cronofy is responsible for ensuring the application receives the calendar data.

How do I control the level of access I have to my users calendars?

You can control the level of access, meaning you can get all the calendar data or only free/busy information.

How long does integration with Cronofy take?

It very much depends on the complexity of your product workflow and the UI design work. We offer off the shelf UI with our Real-Time Scheduling feature and a simple integration with Smart Invites.

Connecting users' calendars

How do users connect to Cronofy?

Your user is directed to an authentication page managed by Cronofy, under the covers this makes use of OAuth2 to control access and security.

What does the user authentication process look like?

Users are required to select the calendar they want to authorize Cronofy to access (eg. Apple, Google, Outlook.com etc) and provide their credentials.

Can we white label the authentication process?

Yes, we allow customization of UI elements. You can add your logo to the header for example.

Data storage

Do you store users’ calendar information?

We store all calendar information including event details, but not their contacts.

Where is your data processing managed?

You can choose between the USA or Germany.

Where is your data hosted?

Either Germany or USA on completely separate instances (no data transfer happens between the two data centers).

Are you planning to open a data center in the UK, Australia, Canada, ROW?

A UK data center is coming soon. There is no ETA available at present.

Are you GDPR compliant?

Yes. You can visit our GDPR page for more information.

Testing

Are there any limitations?

You are limited to 20 users for the duration of your tests.

How do I activate my application?

Please contact us and provide us with your client ID and redirect URLs.

Pricing

How does your pricing work?

Pricing is determined by a) the features you require and b) the total number of users per month. For instance, to organize meetings based on availabilities, it requires the Availability API which is part of the Emerging Plan.

What constitutes a user?

A user is an individual – customer or end-user – who has granted your application access to their calendars. We only recognise them as a user once they have completed the authorization process and connected to Cronofy. A single user can have several calendars synced through Cronofy.

Is it a licence model?

No, it’s an activation model. We only recognize users when they are connected with Cronofy. Billing for the user stops when they are no longer active.

What happens if I go over my included user limit?

We automatically bill you for the additional users at the end of the month. Our team is always on-hand if you want to see which plan best fits your usage.

Billing

How is payment managed?

You can pay monthly via a credit or debit card. If you subscribe to an annual Emerging Plan or above, we can invoice you.

For additional services such as Smart Invites – which is billed monthly – and Enterprise Connect – which is billed annually – we will automatically invoice you as soon as these products are activated.

Technical Support

Can you do the integration for us?

No, our objective is to build the APIs for you or your integration partner to complete the integration. However, if you are looking for an integration partner we can advise.

Do you offer technical review meetings?

We offer technical review meetings for customers on our Emerging Plan and above. Everything else is handled via online support tickets.

How do I connect users with Exchange?

First, Exchange Web Services must be activated. Then the user can connect their calendar through our authentication process.
