Koofr
EU-hosted cloud storage with a 10 GB free plan, an optional encrypted Vault and a 100 GB plan at €2 a month with VAT.
In short
- The free plan gives 10 GB of storage1.
- 100 GB costs €2 a month including 22% VAT, about €1.64 before tax, on a yearly subscription1.
- Koofr Vault is an open-source, client-side encrypted folder included in all plans; other files are not end-to-end encrypted2,6,7.
- Previous file versions are kept for up to two years on paid plans, and deleted files for 30 days on paid plans (7 days on free)4,5.
- Files are stored in the EU, in Germany8.
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.
