About Peergos
Peergos is end-to-end encrypted storage, file sharing and sync that, according to its site, also keeps file metadata private: file names, folder sizes, folder structure, contacts and the list of who you share with are not visible to the provider. It offers a drive reachable from the web, Windows, Linux and Android; on Windows, Linux and Android it mounts as an ordinary drive in the file manager and decrypts as files are opened. Sync works in both directions across devices, and only changed parts of a large file are uploaded. Sharing is done through encrypted follow requests between Peergos users or through secret links that work for people who have never used Peergos and can be given an expiry, a password, a fixed number of uses or write access. The site states that sharing uses a hybrid of X25519 and MLKEM-1024, that the project has had two independent security audits (Radically Open Security and Cure53) published in full, and that it is a non-profit with no investors, debt, advertising or free tier. Apps run in a sandbox on the same encrypted storage and see only the file opened. The homepage text does not state prices; it links to a separate cost page.

Peergos FAQ
Does Peergos hide file names and folder structure, or only file contents?
The site says the server holds none of the file names, folder structure or sizes, and lists what is in your files, what they are called, how folders are arranged, who you share with and who your contacts are as hidden from Peergos.
Can I share files with someone who does not use Peergos?
Yes. Secret links are described as working for people who have never heard of Peergos, and the file is said not to be exposed to the server on the way. A link can be given an expiry, a password, a fixed number of uses or write access.
Which devices and apps can I use with Peergos?
The site lists Windows, Linux, Android and the web. On Windows, Linux and Android it mounts as an ordinary drive, and calendars and contacts sync to the phone's own apps and to Thunderbird over CalDAV and CardDAV.
