Google Chrome Bookmarks, extensions and history. I don't use chrome anymore.
Google Play library, I cleared it in google play but the installs.json and library.json are still huge and contain uninstalled apps.
And lastly all Google Play reviews I did.
(This is not off-topic, since it is about google play and chrome)
There's nothing much we can do except giving you a pointer: if you're an European citizen, GDPR article 17 gives you the right to demand erasure of your personal data. Quoting from paragraph 1:
The data subject shall have the right to obtain from the controller the erasure of personal data concerning him or her without undue delay and the controller shall have the obligation to erase personal data without undue delay …
After that, a list of conditions follows. For your case, the very first one (a) should apply:
the personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed;
Some of the others might as well.
Summing up: if you want those data erased, you should reach out to Google demanding erasure according to Article 17 GDPR. To my knowledge, "without undue delay" is interpreted "ASAP" with a cap of maximum 30 days.
