CuriosityStream: sovereignty score and 8 European alternatives

CuriosityStream is a subscription streaming service for documentaries, ad-free, covering subjects such as science, history, nature and technology. It is aimed at individual viewers and is delivered through its website and apps. According to the provider, new programmes are added weekly, and viewers manage their subscription through a personal account.

CuriosityStream is operated by Curiosity Stream Inc., a US company headquartered in Silver Spring, Maryland. Its privacy policy sets out rights for visitors from the EEA, the UK and Switzerland, such as access, correction and deletion. Personal data is transferred to the United States; as a safeguard the company refers to measures such as EU standard contractual clauses. The privacy policy names no hosting provider or storage location; annual reports filed with the US securities regulator indicate that computing mainly runs on Amazon Web Services. For European users the service falls under US jurisdiction, with exposure to the US CLOUD Act.

Why digital sovereignty matters with CuriosityStream

CuriosityStream 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.

CuriosityStream 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.

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