I've found helpful guides for de-googling here, but I wasn't able to find any for limiting the personal data that is shared with Google before making the switch to other services.

I'd greatly appreciate if anyone could link me to existing guidance or offer guidance here. Some questions I have:

• If you've de-googled, were you able to clear out any of your data from wherever Google captures it?
• Does Google allow you to clear out data upon account deactivation?
• What is the extent of control we have (if any) over our personal data once Google has captured it? Once Google has sold it elsewhere?
