Xattle

Xattle is a repository of quizzes, created by users.

These quizzes can be played in public or in private. Even for public quizzes, responses, comments, results etc. can be filtered by friends.

It is simple and safe. You can play anonymously as a guest. However, a registered user can play on multiple devices (as the same user).

Anyone can deactivate their account, whenever they want, and erase all their activities and data.
