What does Stax Bill do with personal data?
Manage customer payments, subscriptions where applicable, invoicing and billing. That is how Privacyboard describes a typical use of Stax Bill, as a starting point you can edit.
The data usually involved: customer names, email addresses, billing addresses, transaction identifiers and payment information handled by the provider.
Is Stax Bill a processor or a controller?
Most customers use Stax Bill as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for payments tools and it is what Privacyboard suggests.
As a processor, it needs a written agreement with you under Article 28, and you should know which subprocessors it uses. Confirm the role against your own agreement, because the way you use a tool can change it.
Where does Stax Bill store personal data?
Stax Bill does not have one fixed location for every customer. The location depends on the plan, the account and the services you enable.
How to find yours: Check the provider’s privacy center or data processing terms.
Even when the main location is in the EU, ask whether subprocessors or support access involve a transfer outside the EEA, and record it if so.
Which legal basis usually applies to Stax Bill?
For the usual use of Stax Bill, companies most often rely on performance of a contract and legal obligation (GDPR Article 6(1)). Taking payment is part of the contract, and invoices must be kept as accounting and tax law requires.
Many payment providers also act as independent controllers for fraud prevention and legal checks, on their own basis.
This is a starting point, not legal advice: the basis belongs to your activity, and you confirm it in your register.
Does Stax Bill have a data processing agreement?
Checked on 5 November 2026. Vendors change their pages, so check the date.
Stax Bill does not publish the full text of its data processing agreement on a public page. The reference page explains how a customer gets or signs it, usually from inside the account. Article 28 of the GDPR still requires a written contract, so get it and keep a copy.
What we noted when we opened the page: GDPR Statement of Support saying Stax Bill acts as processor and offers a downloadable Data Processing Addendum amending the Services Agreement. Lists subprocessors mainly in the USA, plus Israel and Canada.
A page that exists does not mean you are covered. Whether the agreement applies to you depends on your plan and on what you accepted, so record the decision yourself in your vendor list.
