Maintenance Subscription Terms

Every DayPilot Pro license (except for Web Mini) includes 12 months of maintenance subscription which includes new versions and support as defined below.

The Web Mini license includes 6 months of maintenance subscription that cannot be prolonged.

1. New Versions

New versions include new features, improvements, bug fixes, security fixes and browser compatibility fixes.

The maintenance subscription is the only way to get new versions. It's highly recommended to keep the deployed version up-to-date to prevent compatibility problems and security issues.

New versions are generally backwards compatible. If there are breaking changes, there is usually an option to switch to the original behavior.

The sandbox builds (development versions that include latest changes) are only available as a trial version.

2. Support

  • Support is accessible by e-mail ( and using the public forum (
  • Reaction time: 2 business days

Implementation of new features is not part of the maintenance subscription and it is subject to availability and additional fees. Please contact to discuss the options.

The number of support tickets is not limited but it is subject to fair use (how-to questions exceeding 10 requests per year may be subject to additional fees).

Supported versions:

  • The license agreement may allow modification of the source code. However, the modified versions are not supported.

The maintenance subscription can be renewed for 25% of a new license price (the price valid at the time of renewal), with the exception of Web Mini license where the maintenance subscription is not renewable.

The renewal is not automatic. You will receive two e-mail notifications when your subscriptions is about to expire:

  • one month before expiration
  • on the expiration date

The renewal is optional. If you decide not to renew you can still use the latest version that was released during your existing subscription.

You can renew the subscription before the expiration or during a 6-month grace period after expiration. The new subscription will always start on the expiration date.

Any change of the maintenance price (the percentage) will be announced here, usually at least 12 months in advance.

The subscription maintenance may not be available for products that are no longer available for purchase.


These maintenance subscription terms are subject to change. New versions will be published at this page (
