This page lists the companies that RouteZero Ltd ("RouteZero", "we", "us") uses to process customer travel data on our behalf. For each company, it sets out what we use it for, where the data is stored, and the safeguards that apply if the data leaves the UK.

1. Who this applies to

We publish this list for any organisation ("you") that shares travel data with us under an agreement for our services.

This list covers the data you share with us under our agreement. It doesn't cover other personal data we hold, such as your contact details or visits to our website. Our privacy policy covers the personal data of website visitors, people who contact us, and contacts at our customers.

2. What a sub-processor is

When you share your travel data with us, we process it on your behalf. To process data means to do anything with it, such as storing, reading, or analysing it. A sub-processor is another company that processes that data for us, on our instructions.

3. How we choose them

Before a company processes your data, we check how it protects data, including its independent security certifications. Each company on this list:

  • holds ISO 27001 certification and SOC 2 reports,
  • acts as a processor of your data, meaning it processes the data on our behalf and on our documented instructions, and
  • is bound by a written data processing agreement that sets out how it must protect your data.

7. International transfers

The primary copy of your data is stored in the UK, in Microsoft SharePoint. Your data leaves the UK when we use Anthropic's Claude, which stores data in the United States. Microsoft may also transfer data outside the UK to provide its service.

Each of these transfers is covered by the EU Standard Contractual Clauses with the UK International Data Transfer Addendum. These are standard safeguards the UK GDPR recognises for sending personal data outside the UK.
