Privacy Policy
Last updated: 14 August 2026
AudioSilo Meta is a public, open source audiobook metadata database: this website, a read-only API, and the whole catalogue published as downloadable SQLite releases. There are no user accounts and nothing to sign in to. We set no cookies and run no analytics, advertising, or tracking scripts of any kind.
Who we are
AudioSilo Meta ("the database") is published by KodeStar. Questions about this policy can be sent to kode@audiosilo.app.
The short version
- No accounts, no sign-in, no cookies.
- No analytics, advertising, or tracking scripts - we do not profile visitors.
- The web server keeps ordinary technical logs, used only to run the service and deal with abuse.
- Your library export never leaves your device: /import parses it entirely in the browser.
- The database holds bibliographic facts about published books and the people credited on them - public information about public creative work.
Server logs
Like any web server, ours keeps ordinary technical logs of the requests it answers: the requested URL, a timestamp, the IP address the request came from, and the browser's user agent. These are used only to operate the service and to deal with abuse such as scraping floods or attacks. They are not used to profile anyone and they are not shared.
Search
Search queries go to this site's own API, on the same origin as the page you are reading. They are handled like any other request - the ordinary logs described above, nothing more. There is no search history, because there is nobody to attach one to.
Importing your library (/import)
The import page compares a library export against the database and shows you which of your books are catalogued and which are new. The export file is parsed entirely in your browser. The file itself never leaves your device, and nothing about your library is uploaded to us. Matching is done by asking the public API about identifiers and, for books it cannot match that way, author names - the same requests the search box makes.
The lookup assist (/add)
On the add-a-book page, searching for a title queries libex, a third-party Audible-metadata mirror, directly from your browser. That service therefore sees the text you searched for and your IP address, under its own terms. This happens on /add and nowhere else on the site.
Cover images
The database stores cover art as URLs, not as files - typically pointing at retailer content delivery networks. When a page shows covers, your browser fetches those images from the hosts that serve them, and those hosts see your IP address as they would for any image on the web.
Contributing
Contributions are made on GitHub, through issues and pull requests, under GitHub's own terms and privacy policy. Contributions are public and permanently recorded in the repository's history, and the data itself is published under open licences (CC0-1.0 for the factual core, CC BY-SA 3.0 for the community layer). A contributor's GitHub username is therefore part of the public record and cannot meaningfully be withdrawn later.
People in the database
The database contains bibliographic facts about published authors, narrators and other credited contributors: their names, the works they are credited on, and public identifiers. This is public information about public creative work - the same material a library catalogue or a bookshop listing carries - not private personal data. If you are credited in the database and something is wrong, or you have a concern about a record, please open an issue or email kode@audiosilo.app.
External links
Pages here link out to GitHub, Discord, audiosilo.app and other sites. Once you follow such a link you are on a service governed by its own privacy policy, not this one.
Changes to this policy
We may update this policy as the service evolves. Changes will be reflected by the "Last updated" date above and published at the same URL.
