More than a month after it was acquired by Pinterest, Math Camp announced in emails to users that it is shutting down its photo sharing apps Shorts and Roll at 12:01 a.m. on August 30. The company advises you to download all your photos before then, as they’ll be removed permanently.

You may not have heard of Math Camp, but it’s likely that you’ve heard of the apps that it produced, such as Shorts, Roll, and even Highlight, which was talked about at its debut during the South by Southwest interactive conference years ago. The team behind these services were acquired by Pinterest in July, but not the technology. It was said that the apps would be “sunsetted in the coming weeks,” and now we have a definitive date.

At the time, Math Camp promised that it would open-source many of its libraries and frameworks for developers to work on, but the consumer-facing apps will soon be no more.

The fate of Highlight is currently unknown, but it’s likely that it, too, will be discontinued on August 30, as the Math Camp team shifts to focus on Pinterest’s mobile discovery products.

Here’s an email users are receiving — the text is basically the same for both the Shorts and Roll announcement:

Last month we announced that we were being acquired by Pinterest and that Shorts would be shutting down.

We wanted to let you know that Shorts will officially be going offline this Tuesday, August 30th at 12:01am. Please make sure you share your final photos before then and download any from friends that you’d like to keep.

We can’t tell you how much we appreciate your using the app, and we hope to build lots of great new things for you down the road.

Thanks for using Shorts!
