I just found out about a new app from Consumer Reports for data privacy – Permission Slip. It will submit data privacy requests to companies who you have interacted with, even with different email addresses.
I just started using it, so I can’t say how well it works.
Also, CR has apparently been overwhelmed by the response, so there may be some delays.
Here’s a website, or you can find it on the Google Play or Apple store.
