What kind of files should I store in the Vault?

The Vault is designed for personal files that require the highest level of privacy protection — content that is sensitive or private, and that you want to keep entirely away from PikPak or any third party.
Because the Vault uses End-to-End Encryption (E2EE), only you can view and manage its contents. PikPak cannot index, preview, or access any files stored inside the Vault.
Please note: the Vault should not be your sole storage location for important data. We recommend maintaining independent local backups of any critical files as an additional safeguard.
