Beyond the bundled lists, Vodou reads a few optional local files under ~/.vodou/ that are never bundled, committed, or sent anywhere:

FilePurpose
blocklist.txtYour own extra domains to block, one per line, on top of the bundled tracker list.
safebrowsing_sources.txtAlternative Safe Browsing list URLs, if you'd rather not use the bundled public feeds.
safebrowsing_extra.txtExtra hosts to treat as malicious, on top of the public lists.
