Crumbs service providers
Effective date: 01/09/2026
We use a small number of support companies to deliver our Crumbs service. What data each one handles depends on what it does for us. Each row points to the purpose it serves in “What we collect, and why” in our privacy policy, where the data is set out in full.
Every one of these companies works under a written data processing agreement. They may only use your data to deliver Crumbs to you, never for their own purposes.
Which of these apply depends on the Crumbs product you use and the features you have turned on.
