What Happens After Your Request to Delete Data?

An email will be generated and sent to administrators at your fitness brands facility. The operators and admin team at your fitness brand will have up to 30 days to respond to your request. Each request will be evaluated independently to determine if a deletion of account makes sense or is it in conflict with the contractual obligations your client has signed with you. Hapana will not weigh in or delete your clients' information for you. It will be your business that decides when and if you will honour their request.
