Nobody has to approve it, and there is no request to file with your employer. It happens the moment you confirm.
What stays is your name, your hours, the pay rate that was applied to them, and the jobsite location recorded at the moment of each punch — the latitude and longitude your phone reported when you clocked in and out. Those are your employer's time records.
They stay because they are not only yours: they are your employer's payroll records. Under the U.S. Fair Labor Standards Act an employer must keep payroll records for three years, and those records have to say who was paid. A timesheet whose final week has no name on it is not a record that survives the audit it exists for. Deleting them is not something this app is permitted to do on your employer's behalf.
The location fix on each punch is not required by that law, and this page will not pretend otherwise. It is kept for a different reason: it is your employer's own record of where the hours they paid for were worked, recorded at the moment you said you were there. Erasing their verification of their own payroll is not something this app is entitled to do for you either. If a company would rather not keep it, that is a decision for the company — ask your employer.
What is removed is your login, your email address, your phone number and your personal settings — every way of reaching you and every way of signing in as you. What remains is a line in a pay ledger, the punches it is built from, and a security log of account events — such as an access code issued or used, an emergency account recovery, or this deletion — each one stamped with the network address it came from. That log holds no email address, and it stays because a record of who could get into a payroll system is the only thing that can ever answer whether somebody did.
Email wes@ovrtsitesolutions.com and say which company you worked for and the email address you signed in with. Deletion will be carried out for you, and the same bargain applies: identity removed, payroll records retained by the employer.
What is collected while an account is open is described in each company's privacy policy, served at /privacy on the same address you use to sign in.
