Cloud Storage & WebDAV Setup Guide

Torto syncs your book library, reading progress, highlights, and inline notes across desktop and mobile devices via standard WebDAV. All data is encrypted and transferred directly between your device and your personal cloud storage, with zero relay through any Torto server.

The app includes 6 built-in presets and supports any standard custom WebDAV endpoint.
