Estonia
Cryptee is an Estonian, open-source service that combines end-to-end encrypted storage for photos, videos and documents with a rich Markdown editor supporting LaTeX. Everything is encrypted with AES-256 before it leaves your device, and you can sign up pseudonymously.
Its standout feature is ghost folders, which stay invisible unless you know their exact name, making it the most privacy-paranoid option here and a compelling European alternative to Dropbox or Google Drive for anyone who wants maximum discretion.
