Facts checked 8 Oct 2026

In short

Koofr suits people who want a 10 GB free plan and a 100 GB or 1 TB plan at a few euros a month, with Vault for the files that must stay private1,6. Paid plans keep versions for up to two years and add Office editing4,11. The catch: regular files are not end-to-end encrypted, no family plan or lifetime plan is listed, and the terms say payments are final1,6,13.

Best for: People who want a 10 GB free plan and small paid plans, and will use Vault for private files.
