[Design] Delete Account Functionality
Introduction
This wiki explains the design for delete user account feature. As of now there is no hard delete of user profile flow available in Sunbird. At present, we have functionality to BLOCK/UNBLOCK users.
Background & Problem Statement
Sunbird supports the mobile app for Android and iOS. As per the latest policy update of the Apple App Store and Google Play Store, mandates the user deletion from the app, if the app is having the signup from app. The specific policy mandates can be found using the following links:
Apple App Store Policy - https://developer.apple.com/app-store/review/guidelines/#data-collection-and-storage
Apple App Store Policy - https://developer.apple.com/support/offering-account-deletion-in-your-app
Google Play Store Policy - https://support.google.com/googleplay/android-developer/answer/13327111?hl=en
Registered users must have access to a "Delete Account" option on both the app and the portal. This option will allow them to initiate the account deletion process themselves.
Key Design Problems
User should not able to do the following things after successful deletion of account:
User should not be able to login by using the existing login credentials post account deletion.
Any of the Personally Identifiable Information (PII) of the user, such as name, email, and phone number should not be available in any DB in any format (even encrypted format).
Other than PII data should not be deleted. User transactional data and user created contents (usage, rating etc) are to be retained.
Certificates issued to the deleted users should not be accessible, but should be verifiable. (Storing only the name of the user in Sunbird RC to display in certificate).
External id of the SSO user should be removed.
List the deleted user list to admin dashboard.
Deleted user’s asset should be transferred to the other user after successful deletion.
