Terms of Use

Last updated: November 6, 2026

These Terms of Use ("Terms") govern your use of the Whammy app ("the App"), published by Best Day Labs ("we", "us"). By downloading or using the App, you agree to these Terms. The App is also licensed to you under Apple's Standard Licensed Application End User License Agreement ("Apple EULA"); where these Terms and the Apple EULA differ, these Terms add to it.

Eligibility

You must be at least 13 years old to use the App.

Subscriptions

Full access to Whammy requires a paid auto-renewing subscription purchased through Apple's App Store. Current options and prices are shown in the App before you subscribe — for example, a yearly plan that starts with a 3-day free trial, and a weekly plan with no trial.

• Payment is charged to your Apple ID account at confirmation of purchase, or when a free trial ends.
• If your plan includes a free trial, you won't be charged if you cancel at least 24 hours before the trial ends. Any unused part of a trial is forfeited when you buy a subscription.
• Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your account is charged for renewal within 24 hours before the end of the current period, at the price of your plan.
• You can manage or cancel your subscription in your Apple ID account settings (Settings → your name → Subscriptions).
• Refunds are handled by Apple under its policies; we cannot issue refunds directly.
• Bought a subscription on another device? Use Restore in the App to unlock it.

Songs, Tabs and Your Videos

Whammy displays tabs that you import or find through third-party sources, for personal practice and learning. We do not own the songs or compositions, and we do not guarantee that any tab is accurate or complete.

• You are responsible for the files you import and for having the right to use them.
• Exported videos may include copyrighted music. You are responsible for how and where you share them, and for following the rules of the platforms you post to.
• Videos you make belong to you, subject to the rights of the songs' owners.

Acceptable Use

You agree not to:

• Reverse-engineer, decompile or disassemble the App
• Use the App to infringe anyone's intellectual property
• Redistribute, resell or sublicense the App or content obtained through it
• Use the App in any way that breaks the law

Disclaimers

The App is provided "as is" without warranties of any kind. We don't guarantee that every song will be available, that tabs will be accurate, or that the App will run without interruption or errors. Third-party services the App relies on may change or stop working.

Limitation of Liability

To the maximum extent permitted by law, Best Day Labs is not liable for any indirect, incidental, special, consequential or punitive damages arising from your use of the App.

Changes

We may update these Terms. Continuing to use the App after changes means you accept the updated Terms.
