Things Perkeep believes:
* Your data is entirely under your control
* Open Source
* Paranoid about privacy, everything private by default
* No SPOF: don't rely on any single party (including yourself)
* Your data should be alive in 80 years, especially if you are

While Perkeep can store files like a traditional filesystem (think: “directories”, “files”, “filenames”), it’s specialized in storing higher-level objects, which can represent anything. (photos, likes, tweets, measurements etc)
