Based on the feature you use, Watchdog store data like resource GUIDs, usernames and resource names. We do not store any content created by users
We neither process the data collected nor shared with any 3rd party.
In your azure portal, you can go to Enterprise Applications & delete app named "Watchdog365"
We auto delete any of your data in 15 days from the day you unsubscribe from the product
We do not copy any user created data while you archive a group. All data resides inside your Office 365 tenant. Only data we store at Watchdog365 is the basic details of team like the GUID and few properties of the group
