Questions people ask about Ably Realtime

Where is Ably Realtime's DPA?

Ably Realtime publishes its customer data processing agreement at https://ably.com/data-processing-addendum. We last opened that link on 24 September 2026.

Which legal entity does Ably Realtime contract through?

Ably Realtime Ltd., registered in United Kingdom. That is the name to put in a record of processing or a sub-processor list, not the brand.

What covers a transfer of personal data to Ably Realtime outside the EEA?

Adequacy decision. The European Commission has found the country's protection essentially equivalent to the EU's, so transfers need no further mechanism. Whether that is enough for a particular processing operation is a judgement for the controller.

Does Ably Realtime have a trust or security page?

Yes, at https://ably.com/security-and-compliance. It is Ably Realtime's own page; we link to it rather than repeat what it says.
