When you buy our software, you can use it forever, on as many sites as you like.

The price is not a licence, it is a one-time fee and may also include a period of upgrades and support. If you don't need to upgrade, and you don't need support, you can use the software for as long as you like, even after your upgrade and support period expires.

Here at Les Arbres, we are always working on something. People are always sending us good ideas, and while we make no commitments, we regularly improve and enhance our products. So for our non-free products we offer a choice of payment options for different upgrade periods.

Downloads and Upgrade Periods

When you buy our software, you can receive upgrades for a certain length of time. For example, when you buy Plotalot, you can choose upgrades for 30 days, 2 years, or 3 years. For most countries we send you a personalised link that you can use to download upgrades. Unfortunately, within the EU, we have to deliver our software by email.

If you receive a download link there is a limit to the number of downloads you can receive, but it's higher than you would normally need and you don't need to worry about it. Just don't make your link public!

To help you decide which option to choose, you can check the product's version history to get an idea of how active the product is. Bear in mind that new versions of Joomla sometimes break extensions, requiring an update. Also bear in mind that if you need to talk to us about the extension for any reason, we do tend to pay more attention to users who have demonstrated more support for the product.

Licensing

All our Joomla extensions are Free Open Source Software. In this context, "free" refers to the freedom to copy and re-use the software, and not to the price of the software. Basically, you are allowed to use it in any way you like, for as long as you like, on as many systems as you like.

We use the GNU General Public License, which gives you legal permission to copy, distribute and/or modify the software. Any developers who try to restrict these freedoms are not complying with the GPL and cannot advertise their extensions on the Joomla Extensions Directory.

The only thing we ask of you is that you do not make our paid works publicly available. That would severely reduce our ability to sell them, which would destroy our incentive to continue to develop and support them. So far, this arrangement appears to be generally understood and respected for Free Open Source Software.
