TeraBox: sovereignty score and 8 European alternatives

TeraBox is a consumer cloud storage service for keeping, syncing and sharing files online, with an emphasis on sending large files. It is offered through a website and mobile apps. It is a cloud service: your files are held on the provider's servers rather than on your own devices.

TeraBox is published by Flextech Inc., headquartered in Tokyo, Japan. Independent reviews mention a connection to China's Baidu and link the service's predecessor, DuBox, to storage in China; the vendor itself does not confirm this. The vendor does not state the storage location of your files, and its homepage offers no data processing agreement or GDPR statement. For personal or confidential data of European users, it is sensible to check the terms and the data location first.

Why digital sovereignty matters with TeraBox

TeraBox is headquartered in JP, 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.

TeraBox 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.

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