What it removes
It only removes numbers that really are one of these. Card numbers, IBANs, SINs and Aadhaar numbers must pass their check digit. Social Security and National Insurance numbers must have their exact written format, for example
123-45-6789. So order numbers, phone numbers, tracking numbers, dates and prices are left alone.
What it covers
- What customers write in website chat, email, WhatsApp and Zendesk Messaging, or send through the API, and what callers say on the phone, as transcribed.
- What the agent replies, in case it repeats a number back.
- Replies your team writes from Conversations, and in Zendesk for a Zendesk Messaging conversation.
- An email’s subject, which is the conversation’s title until it is summarised.
- What the agent saves while it works: notes, messages it takes for your team, leads, the details you set it to collect, and the record of each action it runs.
- Test calls in the browser.
What it doesn’t cover
- Names, email addresses, phone numbers and postal addresses. Your team needs these to reply.
- A Social Security number written without dashes. Nine digits in a row look exactly like an order number.
- Messages stored before you turned it on. Nothing already stored is rewritten. Use retention to delete older conversations.
- What actions send to other systems, such as a booking, an API call or a helpdesk ticket. If an action asks for a card number, it receives one.
- On a phone call, the voice model hears the whole call as it happens. Only the stored transcript is redacted.
- Call recordings. A recording is the call’s audio as it was, so a card number read out loud is in it. If you hide personal data because of card numbers, consider leaving recording off.
