Privacy notice

Last updated 10 October 2026

OnCall is a directory that helps clinicians reach the doctor currently on call at the hospitals it covers. This notice explains what personal information the site holds, why, who can see it, and your rights under the Protection of Personal Information Act (POPIA).

Who is responsible

OnCall is run by Dr A Kolia. For any privacy question or request, email cmjahoncall@gmail.com.

What we hold about doctors on the roster

No patient information is collected or shown.

Why, and on what basis

The purpose is to let colleagues reach the doctor on call quickly during patient care. We rely on legitimate interest (POPIA section 11(1)(f)): being reachable is the reason an on-call roster exists. We show only the doctor currently on call for each department, and phone numbers are released only when someone opens a department or taps a call button, through a rate-limited server request. They are not part of the data a browser can download in bulk.

Who can see it

Anyone who opens the site can see names and shift times. Phone numbers are released only to doctors who have signed up and been verified (see below), one request at a time, and are limited per account per day. We do not sell personal information.

What we hold about visitors

ItemWhat it is
Usage eventsWhich page or department was opened, whether a call, WhatsApp, share or report button was tapped, device type (mobile or desktop) and hospital. Used to see how the site is used.
Anonymous visitor IDA random code stored in your browser (local storage) so we can count repeat visits. It does not contain your name or number. You can clear it in your browser settings.
Last hospital openedOn the home page, your browser remembers which hospital you opened last so it can show it first. It is kept only in your browser and is never sent to us.
Feedback formStar rating, and optionally a comment, your name and role, if you choose to enter them. Comments may be quoted on this website with your role only, never your name.
Request-a-hospital formHospital name, city, your role, optionally your name, and an email or cell number so we can reply. Used only to follow up on your request, and kept until it is dealt with.
Report-a-change formThe details you write are sent from your own WhatsApp or email app to us. We do not receive them until you press send there.

We do not use advertising trackers or sell visitor data.

If you create an account (doctors)

To see phone numbers you create an account. We hold:

We use these only to confirm you are a registered practitioner and to run your account. Your details are never shown to other users. A registration match shows that the number exists and the name fits; an administrator can review or remove any account. You can ask us to delete your account and these details at any time by emailing cmjahoncall@gmail.com.

Where it is stored and who processes it

These providers may store data outside South Africa. We use them under their standard data protection terms.

How long we keep it

Roster records are kept for the service's history and usage statistics. If you ask for your details to be removed, we remove them (see below).

Your rights

Changes

We will update this notice when what we collect or how we use it changes, and change the date above.
