Clarification on data storage restrictions

While reading section 12 of the API Terms of Service I noticed the following:

Channel and video-on-demand metadata may be stored for no more than twenty-four (24) hours.

and

Twitch user data for users not created by your application may be stored for no more than twenty-four (24) hours.

I’m interested in storing data from the streams/summary and games/top endpoints in order to track twitch.tv viewership over time. Is there a 24h storage restrictions on the data provided by these endpoints? What about the streams endpoint?

Clarification on this would be much appreciated.
Thanks
