kDrive is the file-hosting service from Infomaniak, a long-established Swiss cloud provider. Your data lives in Infomaniak-owned Swiss data centres running on renewable energy, and kDrive plugs into the wider kSuite ecosystem of mail, calendar and collaboration tools.
It offers excellent value if you want serious storage on Swiss-owned infrastructure, with a generous 3 TB starter tier, making it a strong European alternative to Dropbox and Google Drive for teams that care about data sovereignty.
