Cloud storage is about sync and sharing; a local-first archive is about ownership and availability. They are different tools, and for many documents local-first is the better default.
Cloud storage is best when…
- You need the same file on many devices.
- You want to share files with others.
- You accept that a third party hosts the file.
A local-first archive is best when…
- The document is private: passports, contracts, medical paperwork.
- You need it searchable even without a network.
- You want files on your device, not on a server you have to trust.
Practical note
Local-first does not mean no backup. Keep an encrypted backup somewhere else; the point is that the working archive and its search index live on your phone and work offline.
An app I built for this
Rixin Archive is a local-first document archive for Android: capture via the share menu or camera, organize by project or tag, and search on the device without an account. Free: core archiving flow with ads. Pro: monthly subscription (about $3.99/month in the US) that removes ads and unlocks the full experience. I am the developer of Rixin Archive.
