What is needed to use Buffer in a GDPR-safe way?
Sign a data processing agreement (DPA) if the tool processes personal data on your behalf, minimise the personal data you feed in, and check the vendor's sub-processors. See our DPA guide for the steps.
Our assessment is based on verified data about vendor, storage and certifications (2026). GDPR compliance also depends on how you use the tool. This is guidance, not legal advice. See How we review.
