Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

Data policy removed in Footer and wherever it used due to its wrongly redirecting to Privacy policy page

Test Plan

I've checked by seen the Footer, Now Data Policy removed from Footer and also wherever it's used
