These Terms of Service (“Terms”) are an agreement between you and Mon Louis Ventures LLC (“YaySong,” “we,” “us,” or “our”) governing your use of the YaySong app and related services (the “Service”). By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.
YaySong lets you create personalized songs about the people in your family by providing their names and a few details about them. The Service then creates songs you can play back and save. You can also add an avatar to a family member’s card.
YaySong is made for parents, grandparents, and caregivers who want to make songs for the people they love. Songs are meant to be shared with the whole family, and we build YaySong to keep them appropriate for everyone in it.
You are responsible for your account and everything that happens under it, including anything entered by someone you let use it. Keep your sign-in details secure, and let us know promptly if you believe your account has been used without your permission. If you are under 18, you may use YaySong only with the permission of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your account.
You keep ownership of the names, details, photos, and other materials you submit (“Your Content”). You grant us the limited permission needed to process and use Your Content to operate the Service and create your songs.
You represent that you have the necessary rights and permissions to submit Your Content, including any names, likenesses, or photos of other people, and that doing so does not violate the law or anyone else’s rights.
Subject to these Terms, the songs you create with the Service are yours to use as you like. Songs, including lyrics, music, and cover art, are made by generative AI from the details you provide. Results may vary, and we do not guarantee that any song will meet your expectations.
You agree not to use the Service to:
Some features of the Service may be offered for a fee. If you purchase a paid feature, the applicable pricing and terms will be presented to you at the time of purchase.
Purchases in YaySong are made through Apple In-App Purchase under your Apple Account. Apple’s terms and family purchase controls, including Ask to Buy, apply. We never see your payment details.
Refunds. If you request a refund from Apple, you agree that we may share information about your purchase and your use of it with Apple to help Apple decide your request. This can include whether the songs you bought were already created, your purchase history with us, and general account activity.
The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, to the fullest extent permitted by law. We do not warrant that the Service will be uninterrupted, error-free, or secure.
To the fullest extent permitted by law, YaySong and Mon Louis Ventures LLC will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or goodwill, arising out of or related to your use of the Service.
You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you violate these Terms or if we discontinue the Service.
We may update these Terms from time to time. When we do, we will revise the “Last updated” date above. Your continued use of the Service after changes take effect means you accept the updated Terms.
These Terms are governed by the laws of the State of Alabama, United States, without regard to its conflict-of-laws rules.
