(Sorry for the brief diversion from technical stuff folks, but this looked like a good opportunity for some trademark education and clarification.)

I changed from libTor to libtor as Tor is a registered trademark but lowercase tor is not.

I'm afraid that's not how trademark works. The trademark is infringed by any name that might confuse users into thinking that it is, represents, or is endorsed by the Tor Project.

I already paid for the domain and to make sure people knows is a library to use the Tor network.

I would be happy to paypal (or whatever) you some money to register a different domain -- e.g. libonion.org -- before you get too established in your brand.

(Many generic Tor-related projects use the community-oriented word 'onion', which we have intentionally left out of all our trademarks.)

This is also non-profit and I clarified at the website what is Tor and that carries no guarantee from the Tor Project about quality, suitability or anything else.

Thanks -- that is a good first step.

The guidelines also say that being non-profit I could even use a modified Tor logo.

Actually, that's not what the guidelines say. They say "Please don't modify the design or colors of the logo." Can you point to the sentence(s) that confused you, so we can clean them up?

This is in any case not a trademark, is just a name so people knows what they are getting that comes out almost naturally. A library to connect to the Tor network.

You're making modifications to Tor, and then telling people what they're getting is Tor. I'd say that's a clear opportunity for confusion.

I do not pretend to sell anything. But I made it lowercase however in order to reduce any possible tension.

I understand, and that's why it would be best to resolve the confusion early before users start to associate your software with this name.

In fact, I'd love to have an officially associated project, called something like libtor, that is a library version of the Tor software, endorsed and maintained by Tor (including maintained by you as a Tor project core member). But the way to get there is to become a part of the Tor community and establish a history of doing development and maintenance of libonion the right way, rather than to start out with a confusing name and hope everything works out from there.

Is not that I have to obey any law from the USA as they don't apply to me.

I'm afraid that part isn't true either in this case -- you got your domain from a US-based TLD, and through an ICANN-accredited registrar, so both US trademark law and the UDRP apply. Do a web search for 'icann udrp' for the gritty details.
