Own your data

File over app.

Apps come and go. Your files should not. calternal stores everything as plain files in standard formats, so your data outlives any app, including this one.

  • Plain files on disk

    Your Notes, events, tasks, photos and Budgets are ordinary files in your Home. The database is only an index that can be rebuilt from them.

  • Standard formats

    Markdown for notes, iCalendar for events, vCard for contacts, XMP for photo metadata. Every other tool can read them.

  • Safe writes

    Every save writes a new file and swaps it in. A crash never leaves a half-written file behind.

  • Versions and trash

    Overwritten files keep their old versions. Deleted items go to a trash first.

  • No lock-in, both ways

    One export format moves everything between calternal.cloud and your own server, in either direction.

  • Readable by humans

    Open a Budget or a Daily note in any text editor. It makes sense without calternal.
