TL;DR
Twilio is a cloud communications platform that can be used in a GDPR-compliant way, provided you handle user data responsibly. If you're sending personally identifiable information (PII) through Twilio APIs, like phone numbers, emails, or account IDs, GDPR obligations absolutely apply.
How to stay GDPR compliant while using Twilio
Twilio offers APIs for SMS, voice, video, authentication, and more. These are incredibly useful for personalized communication, but they often involve handling user data. That means you must comply with GDPR if you're operating in the EU or processing EU residents’ data.
Here are the key steps to ensure GDPR compliance while using Twilio.
1. Know what user data is sent via Twilio APIs
Whether you're using Twilio for SMS alerts, OTPs, video calls, or marketing emails (via SendGrid), it's essential to identify what user data you’re sharing. If you’re sending: Phone numbers, Email addresses, IPs, Location data, Call metadata or message logs, you’re processing PII. This requires GDPR compliance, including legal basis, consent (if applicable), and clear privacy disclosures.
2. List Twilio as a data processor in your privacy policy
If Twilio processes any customer data on your behalf (which it almost certainly does), it must be listed in your data processors list. Update your privacy policy to reflect Twilio as a sub-processor. Here’s how you might do it: “We use Twilio, a cloud communications platform, to manage certain messaging and communications. Twilio may process data such as phone numbers and call/message metadata solely on our behalf.”
3. Monitor your security practices
According to Article 33 of the GDPR, any personal data breach must be reported within 72 hours. To minimize risk: Use Twilio's built-in encryption features, Enable 2FA and secure API keys., Monitor access to logs and message history, Audit what integrations you’ve added and what data they access. If using SendGrid (Twilio's email service), also ensure your SPF, DKIM, and DMARC records are correctly configured for security.
Do you need a cookie banner when using Twilio?
No. Twilio doesn’t place cookies on your website by default unless you're using their SDKs directly in your frontend. If you are embedding any Twilio chat widgets or video SDKs, double-check for cookie usage and handle it accordingly through your cookie management platform.
