AstridYahoo has acquired 4 million user to-do app Astrid, which allows users to create task lists on Android and iOS phones and tablets, as well as the web. No financial details were released.

Astrid announced the acquisition itself on its blog, saying that “we are thrilled to announce” that the company has been bought by Yahoo.

Users of Astrid might possibly be less than thrilled, however, as the service will only be maintained as it currently exists for 90 days, after which changes might be made. Users, however, will be able to download any data they have input into the service, if they wish.

CEO Jon Paris thanked Google Ventures and Startup Lab as well as investors Nexus Venture Partners and TMT Investments, but said that Astrid will no longer be accepting premium subscriptions. Users who have paid for annual subscriptions that overlap that period will be getting refunds.

With the purchase, Yahoo’s Marissa Mayer continues to deliver on her promise of more mobile and more acquisitions. Yahoo has also recently acquired mobile video platform OnTheAir, social curation site Snip.it, location discovery app Alike, and mobile recommendations site Jybe.

Paris’ entire statement:

Friends of Astrid,

We are thrilled to announce that we have been acquired by Yahoo!. When we set out to build Astrid, we sought to help as many people as possible become happier, healthier and more productive. We’re really excited to join the mobile team and continue this work with Yahoo!’s goal of “making the world’s daily habits more inspiring and entertaining.”

Over the next 90 days, Astrid will continue to work as is, and we will no longer be accepting new premium subscriptions. To make future changes as easy as possible, we’ll be in touch with users shortly to share how to download data.

We are grateful to the more than 4 million of you who have downloaded our apps, to those who have shared Astrid with friends, family and co-workers, and to all who encouraged us with your kind words along the way. You honored us in so many ways, and we won’t forget you.

We are also grateful to our many mentors and investors:

  • Thomas Korte and AngelPad for your sage advice and assembling a tremendous community of entrepreneurs.
  • Google Ventures and the team at the Startup Lab for teaching us so much.
  • Nexus Venture Partners, TMT Investments, and the amazing angel investors who provided the resource and support we needed to build our products and company.
  • Jump Associates and LUXr for helping us understand our users and build products people love.

To all of you, in both big and small ways you have helped us achieve the success we enjoy today. It is our sincere hope that our work will help you come closer to your own dreams.

Warmly,

Jon Paris & the Astrid Team
