Hello blogq, please don't worry, we did not use anything to track datas, not even Google Analysis. We just wanted to show the thing we just built, and gather honest feedbacks.

For the email sign-in, it is because that, we would like to use the "password-less" approach like Slack did, in order to avoid the hustle of creating and remembering passwords for the users.

We hate spamming ourselves, we respect people's privacy, so we promise we won't do anything spamming with your email. :)
