SyncEtc, the company that makes Tach & Go, handles this request.
If you want SyncEtc to remove what SyncEtc itself keeps about you (a message you sent through a form, a directory listing request, a sign-in help request, or your sign-in), ask here. We email a link to the address you give: open it to send us your request. For anything your organization holds about you, ask that organization: its own privacy policy governs that, and SyncEtc refers your request to it.
