I requested my data back in March 2020 when they were on HN, never got an answer.
They wanted me to upload a photo ID to verify my identity and I was stupid enough to comply.
One commenter said:
This is a case of 'never click "opt-out" on spam'. Clearview is not to be trusted. One should not go through their process. They are not likely to delete the data, and if they have none, they are likely to create a profile for you.
I should have listened, lesson learned.
