When publishing an app that creates user accounts to Google Play, you must provide a web link resource where users can request app account deletion and associated data deletion. See Understanding Google Play’s app account deletion requirements for more details.
SIL International is working with a Gordon College Computer Science senior capstone team to develop a web app to accept requests for data deletion. These requests will show up as tasks in Scriptoria assigned to the project owner and organization admins (either can complete the task).
I will update this post when more details are available.
Thanks,
