Privacy policy

Folda is a small, invite-only music app. This page explains what it collects, why, where it's kept, who else handles it, and how to have it removed. Folda does not show ads, does not sell or rent your data, and does not use it for advertising or tracking.

Your account

You sign in with Google. Folda receives your name, email address and profile picture, and keeps a session so you stay signed in. Only invited email addresses can use Folda.

Music services you connect

Each service is connected only if you choose to, through that service's own sign-in, and can be disconnected at any time on the Sources page. The access tokens are stored encrypted on Folda's server.

• Spotify: your saved songs, your playlists and what you played recently, to show your library and play it. Folda adds a song to your Liked Songs or one of your playlists only when you ask it to.
• Apple Music: your library songs and playlists. Folda adds a song to your library or a playlist only when you ask it to.
• YouTube (read-only): your liked videos and your playlists, so music and DJ sets you've saved there appear in your library and can be played.
• SoundCloud: your likes, uploads and reposts.

Google and YouTube data

Folda's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Folda uses YouTube data only to show and play your own library to you. It is not sold, not shared with anyone except the service providers listed below, not used for ads, and not used to train AI models.

Folda uses YouTube API Services. By connecting YouTube you also agree to the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy. You can remove Folda's access at any time from your Google account's third-party access page, or by disconnecting YouTube in Folda.

What Folda keeps

• Your foldas (collections), Likes, sidebar layout, theme, and recent digs.
• What you play in Folda (song, time, and what you played it from), to arrange your home page.
• A copy of your Spotify and Apple Music libraries (song and playlist details), so a new browser opens with them.
• Music files you upload, kept privately for you alone, and their details.

Your browser also keeps a copy of your library so the app opens quickly. Folda uses one cookie, to keep you signed in; there are no analytics or advertising cookies.

Who else handles it

Folda runs on these providers, which process data on its behalf:

• Vercel (hosting), Neon (the database) and Cloudflare R2 (uploaded files).
• Anthropic (Claude), for the AI features: the title and artist of a song you trace; for “make a folda”, the artist and genre names in your library, a shortlist of song titles from it and your description; and the questions you ask. Anthropic processes these to answer and, under its API terms, does not use them to train its models.

To look up a song's history, artists and sets, Folda also asks public music databases (MusicBrainz, Wikidata and Wikipedia, Discogs, Deezer, the Cover Art Archive, Mixcloud) about songs and artists by name. They receive those names, never your account or library. What Folda learns about public songs and artists this way is shared between users to save repeating lookups; it contains nothing about you.

Keeping and deleting

Data from a service is refreshed while it stays connected. Disconnecting a service in Sources deletes its access token, and its library copy is removed. To delete your account and everything Folda keeps about you, write to the person who invited you; it will be deleted within 30 days.

Children

Folda is not meant for anyone under 13.

Changes and contact

If this policy changes, the new version will be posted here with its date. Questions: the person who invited you. See also the terms.
