Local tools
The listening-history tool reads the JSON files you choose in your browser. It does not upload the files, listening records or results. A summary CSV is downloaded only when you click its download button; that copy remains wherever you save it. The clear button removes the displayed result; closing or reloading the page ends the session. The tool does not use localStorage or cookies.
Games and audio
Number Room and Tone Pairs run in your browser. Scores and progress remain in memory for the session. Tone Pairs generates short tones only when you select a card; it does not request microphone access.
Happy Bird progress
The restored Happy Bird game stores progress on this device using browser localStorage. It does not connect to the original cloud, chat, advertising or online leaderboard services. Clearing this site’s browser data removes local progress. Progress does not sync across devices.
