Citymapper: sovereignty score and 8 European alternatives

Citymapper is a journey-planning app for public transport in major cities, available for iPhone and Android. The company also provides cities and transit agencies with journey-planning and rider-insight tools, and offers an advertising platform that reaches commuters. The service is delivered as a consumer app.

Citymapper Ltd is registered in England and Wales, with its registered office in London. Its privacy policy names Via Transportation, Inc. as its parent, making Citymapper a wholly owned subsidiary of a US group. According to the policy, the service runs on cloud servers, without naming a hosting country. Personal information may be shared with third parties outside the EEA and UK, including Via affiliates in the United States, under the EU-US Data Privacy Framework or Standard Contractual Clauses. For European users and organisations, the data therefore sits with a UK entity owned by a US group and may be processed in the US.

Why digital sovereignty matters with Citymapper

Citymapper is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

Citymapper hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Citymapper is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Citymapper together with your other vendors and gives a total score, a heatmap and the main risk drivers.
