onX Maps: sovereignty score and 8 European alternatives

onX Maps is a family of mapping apps for outdoor activities. The apps include onX Hunt for hunting, onX Offroad for off-road trails, onX Backcountry for hiking, mountain biking, skiing and climbing, and onX Fish for finding lakes. They combine land ownership data with terrain maps and navigation, and an emergency rescue add-on connects users to a crisis response centre. The apps rely on the company's cloud service.

onXmaps, Inc. is based in Missoula, Montana, and is privately held. As a US company it falls under US jurisdiction, including the CLOUD Act. Its privacy policy says the service is hosted in the United States and is not intended for use by residents of the EEA or other international jurisdictions, while listing access, deletion and objection rights for EEA and UK residents. The mapped data is mainly North American land and trail information, so relevance for European organisations is limited. For mapping in Europe, consider providers and open data sources that host in the EU and offer a GDPR data processing agreement.

Why digital sovereignty matters with onX Maps

onX Maps is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

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

onX Maps 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 onX Maps together with your other vendors and gives a total score, a heatmap and the main risk drivers.
