Privacy & Security
solyto was built with privacy as a core requirement, not an afterthought.
What solyto does NOT do
Section titled “What solyto does NOT do”- No tracking — no analytics, no telemetry, no usage data
- No cookies — the only browser storage used is a localStorage entry for authentication
- No background requests — solyto only contacts external services when you explicitly trigger an action (like an import or a recommendation)
- No AI training — your data is not used to train any model
- No ads — solyto has no advertising
What solyto stores
Section titled “What solyto stores”solyto stores the data you enter — notes, todos, calendar events, contacts, library entries, and so on — in your account. On solyto.app, this is stored on servers in the EU. If you self-host, it’s on your server.
Authentication
Section titled “Authentication”solyto uses a single localStorage entry for your authentication token. No third-party auth services are involved. Passkey (WebAuthn) login is supported for passwordless authentication.
External service contact
Section titled “External service contact”solyto contacts external services only when you explicitly request it:
- Weather — Open-Meteo for forecasts, and OpenStreetMap Nominatim for city search on the dashboard widget
- Library imports & search — Deezer, Discogs, Hardcover, Goodreads, IMDb, TMDB, Steam, BoardGameGeek, and Chefkoch, triggered by you
- Release notifications — the backend periodically checks Deezer/Hardcover/TMDB for new releases from your favorite artists/authors
- AI recommendations — library recommendations are generated on demand via an OpenAI-compatible API; nothing is sent until you click the button
- CalDAV/CardDAV sync — syncs only when you have it configured; you can disable it at any time
- Telegram bot — only active if you set it up; messages sent by you
- Notifications — sent to your browser, email, or Telegram when events occur
Nothing happens in the background without your knowledge.
Self-hosting
Section titled “Self-hosting”If you self-host solyto, your data never leaves your server. You control everything. See Self-Hosting.
Open source
Section titled “Open source”solyto is open source. You can audit exactly what it does. The source is on GitHub.
