Megaphone: sovereignty score and 8 European alternatives

Megaphone is a platform for white-label mobile apps for municipalities, hospitality and tourism, from Megaphone Software AG of Visp, Switzerland. Municipalities can alert residents by push notification and SMS, publish news and documents through a content management system, and offer room reservations, contact lists and a chatbot. Content is entered once and published to the app and the municipal website. The apps run on iOS and Android as the customer's own app.

Megaphone Software AG is headquartered in Switzerland, and no parent company is named. The vendor states that development, hosting and operation take place in Switzerland. Its privacy notice lists the sub-processors: server hosting at an Amazon Web Services entity registered in Luxembourg with a Zurich branch, web hosting at Infomaniak and Hostpoint, and push and e-mail providers in the United States. As AWS belongs to a US group, the US CLOUD Act may apply to the Swiss server hosting, and a municipality should check what that means for its own requirements. Switzerland is an EFTA country with an EU adequacy decision.

Why digital sovereignty matters with Megaphone

Megaphone is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Megaphone hosts data in CH, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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