Direct answer

A privacy-conscious digital nomad should treat data minimisation as a risk-reduction approach, not a complete solution. The main limitation is that minimising data is hard to verify from the outside: you can reduce obvious identifiers, but residual signals (like IP-related metadata, browser/device signals, logs held by services, or timing patterns) may still persist. Also, operating conditions change while you travel—networks, device settings, apps, and jurisdictional practices can all affect what gets collected and what you can confirm.

How it works in practice

Data minimisation typically means limiting what you provide and what you enable: fewer sign-ins, less long-lived tracking, restricted permissions, and shorter-lived data retention where possible. “Problems and verification” come in because you must validate two things:

  1. that less data is actually being transmitted or stored in your specific scenario, and
  2. that the signals you care about (tracking, profiling, or correlating activity) are not being rebuilt through other channels.

For example, a workflow that looks minimal may still trigger identification via account-based services, embedded third-party scripts, or browser and device fingerprints.

Practical context: common scenarios and consequences

A realistic scenario is using multiple apps and services across countries while switching between hotel Wi‑Fi, mobile data, and hotspots. A minimisation setting that worked yesterday may not work today because an app updates, a browser feature changes, or a new network introduces different visibility.

Possible consequences include:

  • underestimating how much information is still being sent,
  • relying on a single test result rather than repeated checks,
  • assuming “privacy tools” guarantee anonymity or safe outcomes (which they generally do not).

Limitations to expect

First, a VPN or similar privacy tool does not guarantee anonymity, safety, or access; performance and effectiveness can vary by network, device, location, provider, and time. Second, verification is not universal: you can validate some signals you observe (such as network behavior on your device), but you usually cannot fully audit what every third party stores, how long they keep it, or how they correlate datasets.
