Health Check

Data deletion

If you nominated a practice, or you run a practice that was reviewed, you can ask Sonar Group to delete what the Digital Health Check holds about you. Here is how it works and what to expect.

How to ask

Email morgan@psdesignstudio.com with the practice name and, if you have it, the Health Check reference from your confirmation email or report — it looks like HC-XXXX-XXXX. Say whether you are asking as the person who nominated the practice or on the practice's behalf. We will confirm receipt and complete the deletion within 30 days.

What is deleted

• The nomination: the nominator's name and email, the practice's details and contact, and the notes that came with it.
• The assessment and the report for that Health Check.
• The evidence captured from public sources for that review — the dated copies of the website, listing and social pages.

What is kept, and why

• A record that a Health Check existed and was deleted — the reference, the dates and who asked — so that we can show the request was honoured.
• Anything EssilorLuxottica has been sent already, which is theirs to manage under their own retention.
• Nothing that identifies the practice or the people involved beyond that record.

If you signed in with Facebook

This is separate, and it is for staff rather than for practices or the people who nominate them. If you have signed in to the Health Check with a Facebook account, all that is held is a sign-in credential: an access token, the Facebook account's user id, which permissions were granted, and when.

Remove the Health Check from your Facebook settings and that is deleted immediately and automatically. Facebook gives you a confirmation code at that moment, and the page it links to here will confirm what was deleted. You can also ask us using the email address above.

Deletion is currently carried out by a Sonar staff member rather than by an automatic process, which is why we give ourselves 30 days. The Facebook sign-in path above is the exception — that one is immediate and automatic. Our standard retention periods, and what we collect in the first place, are on the privacy page.
