Question about free plan word and import limits

Hello! I am relatively revived user to LingQ and am slightly confused about the limits of my free plan.

Does the five-article lesson limit apply to the entire time one is on the free plan?
When I try highlighting new blue words, it says I reached my limit even though it has been a while since I last used it. What is the word limit for importing words we didn’t know at first but want to master? Does it apply per day or for the entire duration of one’s free plan?

Free accounts are limited to 20 LingQs. It’s not a daily limit, it’s hard limit.
As Free member you are also limited to 5 Private lessons.

You do need to commit to an upgrade to get value from our application. But, you then get unlimited LingQs and content since you can also import anything from the web into LingQ as a lesson. If you still are unsure, you can invite friends to increase your LingQs limit and if any of them upgrade you can earn points. Visit the invite page for more details - Login - LingQ.
