Privacy-first. Files are never stored on our servers.How your privacy is protectedWhen you upload a file, it is written to the server's ephemeral RAM — never to any disk, database, or object storage. The file buffer is passed directly to the XML parser in memory, and the raw bytes are discarded immediately after parsing completes. Parsed results are stored in a Node.js Mapkeyed to a randomly generated session ID, and are evicted automatically after 1 hour via a TTL timer. No file content, IP address, or personal data is logged or persisted. When you click "Delete data", or when the session expires, the entry is removed from the Map and becomes unreachable — there is no recovery path, no backup, and no third-party service that received the data.
