GDPR & privacy compliance for AI phone calls in Europe

I wanted to open this topic because when setting up my Callin.io agents I had questions about GDPR and privacy compliance in Europe. I’m sure I’m not the only one—AI calls still handle personal data: names, phone numbers, emails, even calendar info.

Here’s what I learned about staying compliant:

1. Call recording notice.
If you have “Record calls = ON” (which I recommend for transcripts and data), you must notify at the start. Something like: “This call may be recorded for quality purposes.”

2. Data minimization.
Prompts should only ask for what’s necessary. Don’t request addresses or payment info unless strictly needed. That’s GDPR’s principle of “data minimization.”

3. Appointments & calendars.
When connecting Google Calendar, names, emails, and times are stored. I solved this by adding in the prompt: “Your data will only be used to schedule the appointment.” Clear transparency.

4. Right to be forgotten.
In Callin you can delete recordings and transcripts from history. That covers you if a customer asks to have their data removed.

5. Human transfer option.
If a user asks to speak to a human for sensitive matters, always enable it. It’s part of respecting their rights.

What I liked most is that, unlike other platforms where you have little control, here you can easily tune prompts, disclaimers, and deletion options to stay GDPR-compliant.
