Yes, Zaurus meets the requirements of the GDPR. It does this, among other things, by implementing standards.
Zaurus complies with the ISO 27001:2013 and NEN 7510:2017 standards. These cover information security legislation.
However, the aforementioned ISO 27001 standard has recently been expanded to include requirements for organizing and safeguarding the privacy of personal data. Zaurus is currently in the process of getting certified against the ISO 27701: 2019 standard. It is expected that this can be achieved by the end of 2020-early 2021.
