Even secrets can be nice. In celebration of International Random Acts of Kindness Week, which took place Feb. 9-15 and the day-long celebration Wednesday,  secret-sharing app Whisper pulled data on posts to determine which city is the kindest.

On Whisper, users anonymously post secrets. The text they type is analyzed and generates a corresponding image other users can then like, comment on and share. Launched in 2012, Whisper has more than 20 million monthly active users. That’s double what the company had in 2014, Whisper announced in December. 

Albuquerque, New Mexico, ranked as the kindest city in the United States, followed by Lexington, Kentucky; Scranton, Pennsylvania; Charleston, West Virginia; Detroit; Anchorage, Alaska; Burlington, Vermont; Tucson, Arizona; San Francisco; and Long Beach, California.

To determine the ranking, Whisper pulled from millions of posts sent from Feb. 1, 2015, to Feb. 1, 2016. Whisper analyzed the text for posts that talked about giving back to the community, being kind to strangers and paying it forward. The company also pulled selections of posts of the week:

I gave a homeless man my shoes. My boss saw me in my socks and, after</p><p>hearing my story, told everyone on the floor they could take their shoes</p><p>off today.


I recently adopted a dog that seemed to hate everyone and everything. He</p><p>was going to be put down, so I adopted him in order to save him and change</p><p>him.
