Effective November 11, 2026. Six String Coach is published by HydroComplete, LLC.
Six String Coach uses your microphone, only after you allow it, to hear the notes you play so it can tune your guitar and score drills and songs. The audio is analyzed inside your browser, on your computer, as you play. It is never recorded, saved, or sent anywhere: not to the developer, not to any server, and not to any analytics, advertising, or AI service.
Your chosen tuning, daily practice minutes, practice goal, recent session scores, personal bests, and Pro status are kept in your browser's extension storage. Uninstalling the extension deletes them.
The optional one-time Pro upgrade is processed by ExtensionPay (extensionpay.com) and Stripe. They receive your email address and payment details under their own privacy policies; the developer never sees your card number. To check whether you have bought Pro, the extension contacts extensionpay.com with an anonymous key it creates for your browser. The extension runs a small script only on extensionpay.com pages, to complete that check; it does not run on any other website.
The extension does not collect your browsing history, the contents of web pages, your location, or any personal information, and it does not use analytics or tracking.
No data is sold, transferred to third parties for unrelated purposes, or used to decide creditworthiness or for lending.
