Breakfast Quay

Commercial Licences

Simple, transparent, global, perpetual

A commercial licence for a Breakfast Quay library gives you the right to use, modify, and redistribute that library in your own proprietary product.

Two sorts of licence are available: a standard licence with an attribution requirement, or a non-attribution licence. Both sorts are perpetual with a one-time fee — no subscriptions or royalties. You can buy standard licences online right here, or contact us to buy any licence offline.

Standard licence: ideal for lower-cost apps

The standard licence gives you the right to use, modify, and redistribute the library code in any number of end-user applications on any platforms, but you must credit us prominently within the application. Please read the specimen copy (linked in the table below) carefully before buying.

Non-attribution licence: ideal for almost anything

The non-attribution licence gives you all the same rights as the standard licence, but you do not need to credit us at all. It is completely straightforward and undemanding.

Important information

Your licence is issued by Particular Programs Ltd, author and copyright holder of the Breakfast Quay libraries.
All prices are quoted exclusive of VAT, in pounds sterling (GBP). VAT (sales tax) will be calculated during online payment or invoicing.
Online payment is via credit card or PayPal. If you would prefer to pay by bank transfer, please contact us directly.
When you buy a licence, you get only the licence: there is no separate commercial edition of the library code itself. You should download, build, and evaluate the library you are interested in before you buy a licence for it. Proceed only when you are satisfied with the library.
Licences permit distribution, not development, and therefore are issued to publishers, not to developers. You must ensure that the name of the purchaser is the same as that of the company that is publishing the software. If you can't do this with an online payment because your card or PayPal details are not the same as the publisher, please contact us and arrange a bank transfer instead.
To qualify for a Small Publishers licence, the publisher to whom the licence is issued must have fewer than 10 employees at the time of purchase of the licence. (The licence is perpetual, so you don't have to upgrade if you become a bigger publisher later, but it cannot be resold to an existing big publisher.)
The Standard Licence with attribution requirement is available to publishers of any size.
When you buy a licence online, you will receive a digital copy of the licence document stamped with your name and email address, and we will retain a record of the transaction so we know you have the right to distribute your software using the library.

Support

The licence terms do not include a formal support agreement. We're happy to answer routine technical questions from current or prospective licensees without charge, but if your requirements involve significant integration assistance or development, we may be able to offer this separately at a standard day rate. Please ask us for details.
