Opinio: sovereignty score and 8 European alternatives

Opinio is online survey software from ObjectPlanet AS, a company founded in 1998. It is used to create surveys, collect responses and generate reports. Organisations can use it in three ways: as a hosted service managed by ObjectPlanet, as a dedicated instance on their own hostname, or as a self-hosted licence installed on their own servers, including multi-server clusters. The range covers a single survey account up to clustered installations.

ObjectPlanet AS is based in Oslo, Norway. According to the company, it is owned mainly by its founders and employees and one external investor, so no foreign majority owner is named. Norway is part of the European Economic Area, and the company's data protection policy states that customer data is stored on servers in Norway or another EU country and is not transferred outside the EEA. That policy dates from 2018, so current commitments should be confirmed in the contract. With a self-hosted licence, the software and its data stay on the organisation's own infrastructure.

Why digital sovereignty matters with Opinio

Opinio is headquartered in NO, which falls under the GDPR through the European Economic Area. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Opinio scores best on data residency.

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