pCloud

pCloud is a cloud storage and file synchronisation service offering individual, family and business plans, with client side encryption available as pCloud Crypto and a password manager, pCloud Pass, alongside. It sells monthly, annual and lifetime plans.

The lifetime option is genuinely unusual and worth understanding rather than dismissing. Cloud storage is otherwise a permanent subscription, and over a decade the cumulative cost is substantial. A one time payment changes the arithmetic considerably, while transferring risk to the buyer, since the value depends on the company continuing to operate. That is a real trade rather than a marketing gimmick.

Client side encryption is the other distinguishing feature and the distinction matters. Most providers encrypt files at rest, meaning the provider holds the keys and can decrypt on request. Encrypting on the user's device before upload means the provider cannot read the files at all, which changes what a legal demand or a provider breach can expose. It also means a forgotten password is unrecoverable.

The family plan is a practical inclusion, since households share storage in practice and buying several individual subscriptions is how most services handle that badly.
