Effective date: August 25, 2026
Chess PGN Database Narrator is a Chrome extension that lets you browse, study, and listen to narrated PGN chess databases entirely on your own device. This page explains what data the extension does and does not collect.
Every PGN file you open — every game, move, comment, and annotation — is parsed and rendered entirely on your own machine. There is no server, no upload, and no sync: nothing about your files, your games, your own analysis, or how you use them is ever sent anywhere, by us or anyone else.
A few small preferences are saved locally in your browser's local storage: your last-viewed position in each database, your preferred board orientation per database, your chosen narration voice and speed, and your recents list. These stay on your device, are never transmitted anywhere, and are deleted if you uninstall the extension.
Separately from the above, the extension sends a small number of anonymous usage events to Google Analytics (via the GA4 Measurement Protocol) to help us understand how the extension is actually used and guide future improvements. These events record actions like opening the extension, opening a PGN file, clicking a game or a recent database, switching Training Mode or board orientation, starting/pausing narration, and finishing a game.
Each event is tied to a random ID generated and stored on your own device — not your name, your Google account, your email address, or any other identity. These events never include the contents of your PGN files, your games, your comments, player names, or any other chess study material — only the fact that an action happened is recorded, never what you were studying when it did.
As with any web request, Google's servers can see the IP address the request came from, which Google may use to derive a coarse, non-precise location (such as country) for aggregate reporting. We do not otherwise collect or transmit location data ourselves.
We do not collect personally identifiable information, health information, financial or payment information, authentication credentials, personal communications, web browsing history, or the content of pages you visit. We do not sell or share your data with any third party other than Google Analytics as described above, and we never use any data for purposes unrelated to understanding and improving this extension.
If this policy changes, the updated version will be posted at this same page with a revised effective date.
