Solco analyses your music on your computer. Your music files, library, playlists and analysis are never uploaded. This page lists everything Solco does send. The full legal notice is the app privacy notice.
Error and crash reports
Official Solco releases send error and crash reports automatically, so problems can be fixed. A report holds the error, what led up to it, and details about the app version, operating system, graphics and analysis. It can name tracks and parts of file paths, with your user folder's name replaced by ~. It never includes your music, your library or your credentials. A crash can also send a small memory snapshot of the app.
Reports go to an error tracker in Germany: Sentry's EU region for builds up to 0.9.0-alpha.2, and from the next alpha on, Solco's own error tracker at errors.plenty.is, on our server in Nuremberg, with no third party. There is no switch for them in the app during the alpha.
Usage counts
Once a day, Solco sends a ping with a random installation ID, the Solco version and your operating system, so we know how many people use which version. No music, file paths or library data. Turn it off with Share usage counts in Settings › About.
Update checks
Solco asks GitHub for the list of releases when it starts and once a day, sending only its version. Downloads also come from GitHub. Turn this off with Check for updates in Settings › About. See "Updating Solco".
Tag and cover lookups
When you look up tags and covers, Solco sends search details such as artist, title or an audio fingerprint (a short code computed from the sound, never the audio itself) to MusicBrainz, AcoustID and Discogs. Lookups run only when you start them on the Tags page. Keys you save in Settings › Tags & covers stay on your computer, outside your library.
Playlist assistant
The playlist assistant is optional. Before it sends anything to Solco's service, you choose to share your requests, the conversation and a summary of your library: how many tracks you have, your genre and style names with their counts, and how many tracks are analysed. No audio, file paths or track titles, though anything you type is sent. Solco's service passes it to OpenRouter and a model provider, and keeps no copy of the conversation unless a request fails unexpectedly. You can also connect your own provider, or a model on your own computer with Ollama.
Feedback
Messages you write in Feedback go to the Solco team's support system (Chatwoot, which we run ourselves at support.plenty.is, on our server in Helsinki) only when you send them, with your Solco version, operating system and processor type. An email address and the diagnostic summary are sent only if you add them, and you can read the summary first. The conversation stays in the support system until it is deleted. The chat on this help center goes to the same support system, with the email address and name you give it.
Diagnostic reports
A report from Settings › About › Report a problem is made on your computer and never uploaded by Solco. You read it, then copy or save it yourself. See "Contacting the Solco team".
