pCloud is a Swiss cloud storage service for files, photos and documents, with desktop, mobile and web apps, EU or US data regions and a free plan to start.

Lifetime plans - pay once for 500 GB to 10 TB instead of a monthly subscription.
Client-side encryption - files in the Crypto folder are encrypted before upload, so only you hold the key.
Sharing and backup - password-protected share links, file requests, 30-day version history and automatic device backup.

Best for freelancers and small teams that would rather buy storage once than rent it, with Swiss privacy law and a choice of EU or US data centres behind it.
