Terms of Service

1. Acceptance of Terms

By accessing or using our Services, you confirm that you are at least 13 years of age and agree to comply with these Terms and all applicable laws and regulations. If you do not agree, you must not use our Services.

2. License

We grant you a limited, non-exclusive, non-transferable, revocable license to use our applications on devices you own or control, solely for personal, non-commercial purposes. This license does not allow you to:

• Copy, modify, distribute, or create derivative works of the application
• Reverse-engineer, decompile, or disassemble any part of the application
• Remove or alter any proprietary notices or labels
• Use the application for any unlawful or unauthorized purpose

3. Advertisements and Rewarded Content

Our applications may display advertisements served by third-party ad networks, including Google AdMob. Some features may offer optional rewarded advertisements that temporarily unlock premium content in exchange for viewing an ad.

• Rewarded content unlocks are temporary, are separate from Premium subscriptions (Section 4), and do not constitute a purchase or subscription
• Availability and duration of rewarded content may change without notice
• Participation in rewarded ads is entirely voluntary; core application functionality remains available without viewing ads

For details on data collected by ad services, see our Privacy Policy.

4. Premium Subscriptions

MetroTune offers optional Premium subscriptions that keep Premium features active and banner ads hidden while the subscription is active. Core features remain available without a subscription.

• Monthly and annual plans are offered. Plans and prices, which may vary by country, are shown in the app before you purchase
• Payment is charged to your Apple Account or Google Play account when you confirm the purchase
• Subscriptions renew automatically at the end of each period at the then-current price unless you cancel before the renewal date, as set by the App Store or Google Play
• You can manage or cancel your subscription at any time in your Apple Account or Google Play subscription settings, or from Help → Manage subscription in the app. Cancellation takes effect at the end of the current billing period, and Premium remains available until then
• If a free trial or introductory offer is provided, its terms are shown before purchase, and any unused portion of a free trial ends when you purchase a subscription where the store requires it
• Purchases can be restored on another device signed in to the same Apple Account or Google account from Help → Restore purchases. Apple offer codes and Google Play promo codes can be redeemed from Help → Redeem code
• Payments and refunds are handled by Apple or Google under their policies. Archet Studio LLC cannot issue refunds directly
• We may change the features included in Premium or subscription prices. Price changes are communicated and applied as required by the App Store or Google Play

For iOS purchases, the Apple Standard End User License Agreement also applies. For details on subscription data processing, see our Privacy Policy.

10. App Store Terms

If you download our application through Apple's App Store or Google Play, you also agree to the terms of the respective platform. In the event of a conflict between these Terms and the app store terms, the app store terms shall prevail with respect to the app store's scope.

• Any claims relating to our applications should be directed to Archet Studio LLC, not to Apple or Google
