Notes on this comparison
We compare published features, not independently tested security. A red cross earns no credit: the feature is unsupported, has a drawback, or is labelled “Not advertised” because we found no claim in the checked sources. “Not advertised” does not prove a feature is absent. An amber dash means documented partial support. A grey question mark is reserved for checks we could not assess and is excluded from the ranking score.

What’s the difference between Sealby and Proton Drive?
Sealby keeps private photos, files and notes in separate vaults on your device. Proton Drive is built for encrypted cloud storage and sharing through a Proton account.
What Proton Drive is built for
- End-to-end-encrypted cloud storage
- Large storage plans, sharing links and apps on multiple platforms
- Access to the same files across devices through a Proton account
What to consider
- Requires a Proton account — your identity is attached to your storage
- Your encrypted data lives on their servers; its existence and size are knowable
- No deniable vaults, no duress PIN — a locked drive still visibly exists
- Cloud-first: not designed as a sealed, local-only vault
The honest verdict
Choose Sealby for personal vaults without sign-up. Choose Proton Drive for a cloud drive with storage plans and sharing links.

Common questions
Isn’t end-to-end encryption the same everywhere?
The cryptography is similar. The trust model is not. An account-based service knows who you are, that you store data, and roughly how much. That information can be demanded. Sealby has no account and no server, so there is no one to ask and nothing to list.
Can Sealby replace my cloud drive?
No, and it does not try to. Sealby is for the files that should be sealed: private photos, documents, notes, recovery phrases. Premium adds encrypted iCloud backup and sync of those vaults. It is still a vault, not a file-sharing drive.
