Stats for brands


#1

Hi,
i would like to create a program that performs queries (search / streaming ???) for twits using the brand names of some of my customers.
Then I would like to gather statistics ONLY (not storing the twits for more than some minutes until processed) for the twits.

For example:

produce graph with brand mentions during week/month/year
produce graph with brand mentions vs hashtags during week/month/year
produce graph with brand mentions vs other brand names/words during week/month/year

there is a lot of other graphs my customers would be interested in, of course.
One sample i have found on the net would be : http://trendistic.indextank.com

The relevant question here is:
I will not store the messages but I will store extensive statistics and produce pdf documents to sell or make available to customers.
I will not store usernames/id’s and all info will be statistc only and anonymous.
it will be sold as graphs or live graphs on website for registered customers.

Is this legal?

Thank you.
