Question re text reading sites/programs: LingQ, LWT, Readlang

Regarding the sites LingQ and Readlang, and the desktop program LWT (Learning With Texts), I was wondering if there is a limit to how many texts one can import total, and I mean for the paid versions of LingQ and Readlang. While I suspect there is no limit for LWT, for the paid websites can one just import gigabytes of texts at will?

You can ask. Also consider bandwidth usage and copyright. At Readlang you keep the copyright. At LingQ, too long to read .
LingQ is also talking about bandwidth usage limits.

I probably was not very clear. By "import" I mean upload and store, so it would really be storage limits rather than bandwidth. That is, could you upload 5 gigs of texts to be there for you to read as long as you subscribed or is there a limit to how much storage space they will let you use? I could probably go read their TOS but am too lazy to do so, and if the question has been asked in their forums, I think the forums at LingQ now only let those who are not registered and logged in just see the first post in a thread.

Haven't seen it mentioned on Readlang. LingQ, to much to read, don't know.
