Zero to Drop

Terms of Use

Last updated: 30 October 2026

1. The agreement

These terms are an agreement between you and the developer of Zero to Drop named on the app's store pages ("we", "us"). By using the app you accept them. If you got the app from the App Store, Apple's Standard Licensed Application End User License Agreement also applies; these terms add the rules of our service. Apple and Google are not parties to these terms and are not responsible for the app or its content.

2. Who can use it

You must be at least 13. If you are under the age of majority where you live, a parent or guardian must agree to these terms for you.

3. What you record

You are responsible for what you record and post. By recording you confirm that:

  • you have the right to record it;
  • if another person's voice can be heard, they agree to it being recorded and, if you post it, published;
  • you are not recording published music to get around someone else's rights.

The app refuses input that sounds like recorded music, but that check is automatic and does not replace your responsibility. Zero to Drop works only with sounds recorded in the app; it does not import files.

4. What you own

Your recording is yours, and so are the tracks you make from it. We claim no ownership of either.

  • Tracks made by the local engine — everything the app builds on your phone without an AI backing — are yours to use for anything, including commercially.
  • Tracks with an AI backing are for personal and social use: listening, sharing, posting on social networks. Commercial use is covered only by the licensed export, which uses a model trained on licensed material and is marked as such in the app. AI-generated material may not be protected by copyright in every country, and the provider that generated it may have its own terms.
  • AI-generated parts are labelled as AI-generated wherever the track is shown: in the app, in the feed, on the share page and in the video. Do not present them as a recording of a real performer.

5. Posting to the feed

Posting is optional. When you post a track, you give us a worldwide, non-exclusive, royalty-free licence to store it, show it and play it to others in the app and on its public share page, for as long as it is posted. You can delete a post at any time.

Sharing the sound itself. If you switch on Share the sound itself, every other user gets a worldwide, non-exclusive, royalty-free licence to use your sample to make their own tracks in Zero to Drop, to post those tracks to the feed, and to share them anywhere for personal and social use. This licence cannot be withdrawn for tracks already made before you delete your post. Do not switch it on for a sound you are not willing to give away on these terms.

6. Rules for posts, with zero tolerance

We do not tolerate objectionable content or abusive users. Do not post, name a sound with, or use the app to produce:

  • anything illegal, or anything that infringes someone else's copyright, trademark, privacy or publicity rights;
  • hate speech, harassment, bullying, threats or content that encourages violence or self-harm;
  • sexual content, and anything that sexualises minors;
  • someone else's voice without their permission, or content meant to impersonate or deceive, including passing off AI output as a real artist;
  • spam, scams, or links meant to lure people off the app;
  • private information about anyone.

Reporting and blocking. Every post and every AI result has a Report button. You can block a creator from any of their posts; their posts disappear for you, and you can undo this in Settings. Posts reported by several people are hidden automatically until we review them.

What we do. We review reports and act on them within 24 hours: we remove content that breaks these rules, and we may stop the device that posted it from posting again. Serious or repeated violations can lose access to the feed and to AI features.

Copyright and other complaints go to support@zerotodrop.com with a link to the post (the share link works). We handle them within 24 hours as well.

7. AI-generated content

AI backing tracks and Live mode are produced by third-party models. The output can be unexpected. If an AI result is offensive or wrong, report it from the app — we use these reports to improve our filters and to contact the provider. Live mode streams your microphone to Google while it runs; the app asks for your consent first.

8. Pro and purchases

  • Subscriptions (Zero to Drop Pro, monthly or yearly) are paid through your Apple or Google account at confirmation of purchase. They renew automatically at the price shown in the app unless you cancel at least 24 hours before the end of the current period. Manage or cancel in your App Store or Google Play account settings — we cannot do it from the app.
  • One-time purchases. If the app offers credits or a licensed export, they are consumable: used up when you spend them and, like all consumables, not restorable later; unused credits belong to this installation of the app. Restore purchases restores subscriptions.
  • Refunds follow Apple's or Google's rules. We do not process them.
  • The free tier stays free: the local engine has no limits. Daily AI limits and prices may change; we will tell you in the app before a change that affects a subscription you already have.

9. The service

The app is provided "as is". AI generation, the feed and Live depend on third-party services and may be unavailable or change. The local engine works offline and does not depend on them. We may suspend access for anyone who breaks these terms.

10. Liability

To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability is limited to what you paid us in the last twelve months. Nothing in these terms limits rights you have as a consumer that cannot be limited by contract.

11. Changes and contact

If we change these terms in a way that matters, we will show the change in the app before it takes effect. Questions: support@zerotodrop.com.
