The App currently provides guitar learning, practice, and lookup assistance based on built-in guitar chord, root-note, mode, and progression data.
The availability of different features may vary depending on the version, region, device environment, system version, or subscription status. For example:
Some extended chord types are available only to premium users;
Some mode content is available only to premium users;
Some chord progressions are available only to premium users;
Reverse lookup may be subject to a daily usage limit for non-premium users.
We may add, remove, modify, suspend, or adjust features as needed for product iteration, maintenance, or compliance purposes.
The App currently includes premium subscription / unlock mechanisms. In the current project, they include:
Weekly subscription

You may manage or turn off auto-renewal through your Apple account settings;

If you purchase a lifetime unlock product, it is generally a one-time purchase and does not renew automatically. However, the final details are subject to the actual product description displayed in the App Store.
