Questions people ask about Extend

Where is Extend's DPA?

Extend publishes its customer data processing agreement at https://dpa.extend.app/. We last opened that link on 28 October 2026.

Is Extend's DPA the same thing as a data processing addendum?

Yes. A data processing agreement and a data processing addendum are two names for the document Article 28 of the GDPR requires between a controller and a processor; vendors use both, and some call it processor terms. What it has to contain does not change with the name. Extend's is at https://dpa.extend.app/.

Where is Extend's sub-processor list?

Extend publishes the list of its own sub-processors at https://extend-app.notion.site/Extend-Authorized-Sub-Processors-4d2b4a0c2cf046cf8f1e72576b88d21b. We last opened that link on 28 October 2026.

Which legal entity does Extend contract through?

Extend Enterprises, Inc., registered in United States. That is the name to put in a record of processing or a sub-processor list, not the brand.

Where is Extend's trust center?

Extend publishes it at https://trust.paywithextend.com/. A trust center, trust page or security page is the same thing under different names: the vendor's own account of how it protects data, and the place it keeps its certifications. It is Extend's page, so we link to it rather than repeat what it says.
