F.A.Q.

How much do you earn with contributions, what do you do with the money?

Current goal: $4000 per month

We’re completely transparent, you can read here how much we earned for the last 30 days, from how many contributors. This includes both one-time donations and memberships (subscriptions).

There’s approximately one download every two minutes.

The contributions we get are used to cover all expenses (servers, maintenance, etc.) and the rest is just a part of what’s needed to pay the actual develpment.

These counters are updated approximately every hour.

Will I get an invoice for my donation or membership contribution?

Yes! You’ll get an automatic receipt by e-mail just after your payment. And if you need anything else, like a proper invoice, just contact us and we’ll be happy to help.

Is my contribution tax-deductible?

It depends on the laws in your country, but in general, if you’re a professional, contributions can be deduced from your income; in this case you’re not making a donation, you’re buying our service to deliver the software to you; contact us to get the corresponding proper invoice, additionally to the automatic receipt you’ll get after your payment.

If you’re an individual, contributions can’t be tax deductible for now. It’s our goal to be an officially recognised non-profit organization, but it’s a long journey, and the process differs in every country…

Are there any other ways to help, besides donations and membership?

If you can’t afford a donation or a membership – though you can donate the amount of your choice – we always welcome new contributors! There’s a lot to do, not only writing some code, but also contributing to the documentation and guides, tutorials, translations, bug reports, feature request, communication and public relations…

Here is our contributor’s guide

If you’d prefer, buying nice products from our store also helps! We have nice, high-quality clothing and accessories to sell.

I can’t afford or I don’t want to donate, how can I still use the software?

Our software is free, as in freedom.

You have the same rights whether you make a donation or not. Not everyone can afford to give some money, and we’re fine with that. Note that we welcome any kind of contribution, there’s always something to do, like translations, fixing bugs, contributing to the doc, creating examples and tutorials…

Why do you call your tools Free Software if I have to pay for it?

You have to understand the word free as in freedom or in free speech – what we call Libre in French – and not as in free beer. We’ve tried for more than ten years to deliver everything we do for completely free, relying only on voluntarily donations, and that just wasn’t enough for us to continue our work.

So we have to sell the software, but you’re still free to use it as you wish, redistribute it (for free if you wish), modify it, and share your modifications.

We invite you to read this to know more about this interesting subject.

Do you even have the right to sell a program released under the GNU General Public License?

Yes, the right to sell copies is part of the definition of free software.
