Sub-processors
Third-party services that process data on behalf of SpeyBooks.
We only share the minimum data required for each service to function.
What is a sub-processor?
Under UK GDPR, we're required to disclose any third-party services that handle your data on our behalf. These are our "sub-processors". Each one is engaged under a data processing agreement that includes confidentiality, security, and data protection obligations.

Data Residency
Your financial data is hosted at Hetzner's data centres in Germany (EU). Encrypted database backups are replicated to AWS in London (eu-west-2, UK). Data never leaves UK or EU jurisdiction. The EU holds a UK adequacy decision, so this arrangement complies fully with UK GDPR.
Changes to this list
We'll notify you by email at least 30 days before adding any new sub-processor. If you object to a new sub-processor, you can terminate your account and export your data before the change takes effect.
Questions or objections can be raised by contacting support@speybooks.com.
