Shortly URL Shortener 2.1
Bit.ly stores a history of all shortened URLs and their statistics on their servers. Since all Shortly users share the same key, history of all Shortly users are pooled together.
No personally-identifying information is stored. No single user's history is available individually. All information available is as collective information for all Shortly users.
This information can be viewed using the shared login and API key present in your copy of Shortly. Again, it is not possible to see the history of a single user.
