Maybe It's just me, but I think the free tier description on the pricing page [1] is confusing.

- (CHECK) Use the full set of Gleek diagramming features

- (CROSS) Limited to 5 diagram files

- (CROSS) Limited to 40 diagram object

- (CROSS) Diagrams are stored on Gleek servers

- (CROSS) Share links to diagrams using your favorite collaboration tool

- (CROSS) Priority support on Slack

There are checkmarks and crosses. The first item seems clear because it had a checkmark and is included in the free tier. But it seems to me that the next two items (limited to 5 diagram files and 40 diagram object) are also included, but they have a cross next to them. While the last two items also have a cross but are not included.

Lastly, I think there is a small typo and the "40 diagram object" should be "40 diagram objects."

Good luck!
