"Not found" means our reader didn't find it on the public pages it could read; the vendor may still publish it.

Does Buffer train AI on your data?

Our reader didn't find a statement about training AI models on customer data on the Buffer pages it could read. Buffer may publish one elsewhere, for example in a help center, AI terms or a trust portal. Ask the vendor in writing and check its DPA and AI terms.

Certifications Buffer claims

No security certifications were mentioned on the pages we could read. Buffer's trust page may load them with JavaScript.

Privacy laws and frameworks mentioned: GDPR, CCPA/CPRA, EU-U.S. Data Privacy Framework. These are laws the vendor says it follows, not certifications.

A certification on a website is a claim. For anything sensitive, ask Buffer for the SOC 2 report or ISO certificate.

Buffer subprocessors

Our reader didn't find a subprocessor list on Buffer's public pages. It may be published somewhere we couldn't reach, such as a trust portal that needs JavaScript or a login. Ask Buffer for it if you need it.
