Article 3. Description of the Service

2. Songs you do not save become unplayable after a certain period of time, in accordance with the specifications of the Service. Songs that have become unplayable cannot be restored.
3. Detection of transition points is an estimate based on the Device's sensors and location information, and we do not guarantee that it will always be accurate.
4. The content of the Service, the number of songs that can be saved, and the features provided may change without notice.

Article 4. Accounts

1. Users may begin using the Service as anonymous guests. By registering with an Apple or Google account, Users can transfer their data and purchase Premium.
2. Guest data may be lost if the app is deleted or the Device is changed.
3. Users shall use their accounts solely for the purpose of using the Service and shall not transfer, lend, sell, or buy them to or from any third party. Any use through a User's account is deemed to be use by that User.
4. If a User discovers that their account has been used without authorization, the User shall report it to us and make reasonable efforts to remedy the situation.

Article 5. Premium (Auto-Renewing Subscription)

1. Premium is an auto-renewing subscription purchased on a monthly or annual basis through the App Store or Google Play. The price is the amount displayed on the purchase screen and in the store.
2. Purchasing Premium requires registering an account with Apple or Google. Guests cannot purchase Premium.
3. If a free trial is offered, it automatically converts to a paid subscription at the end of the free trial period. If you cancel during the free trial period, you will not be charged.
4. Your subscription automatically renews unless canceled at least 24 hours before the end of the current period, and you will be charged upon renewal.
5. To cancel, use the subscription management screen in the App Store or Google Play. Deleting the app does not cancel your subscription.
6. Refunds are subject to the terms and procedures of each store. We do not issue refunds except as required by law.
7. When your subscription expires, Premium benefits are unavailable. Past Trails and rediscovery of unsaved songs are limited to the latest 30 calendar days, including today. Resubscribing does not restore records outside this period. Saved songs and custom playlists are not deleted merely because 30 days have passed.

7. We neither license nor warrant any use of Generated Songs by Users outside the Service (such as recording, reposting, distribution, or derivative use). Any dispute between a User and a third party arising from such use shall be resolved by the User at the User's own responsibility and expense, and we bear no liability for it.
