Why now?

Clue has been around for six years, and since then, our community has grown to millions of users. That’s something we’re really proud of and we want to continue to be around for our users for as long as possible.

This also raises the questions:

How can Clue be a sustainable company?

What is best for the people who use Clue?

What kind of world do we want to help create?

The answer was really clear. We wanted to build an app that’s supported by you and other users like you—not by selling your data, but by creating real value in your lives. We decided that the best way to do this would be to allow users to donate to us directly either via Paypal or supporting our efforts with a subscription to Clue Plus.

Happy Clue users
