Terms of Use

Lullo · Frank Apps · Effective October 8, 2026

In short: Lullo is free to use with ads. A one-time Premium purchase unlocks every sound and version, the Premium mixes and playback without time limits, and removes the ads. The sounds are for your personal listening in the app. Lullo is not a medical device: follow safe sleep advice and keep the volume low.

1. Agreement

These terms apply to the Lullo app (“the app”) by Frank Apps (“we”, “us”). By downloading or using the app you agree to them. If you do not agree, please do not use the app. If you got the app from the Apple App Store, Apple’s Standard End User License Agreement also applies; if the two differ, these terms add to it rather than replace it.

2. Your licence to use the app

We give you a personal, non-exclusive, non-transferable licence to use the app on devices you own or control, for your own non-commercial use. You may not:

The app, its design and its sound files belong to us or to the people who licensed them to us.

3. Free version and Premium

The sounds, mixes and features may change over time. We try not to remove what Premium users rely on, but some content may be replaced, for example when a recording’s licence ends.

4. Downloads and internet

Some sounds are downloaded the first time you play them. Your mobile operator may charge for data. Downloads need our file service to be available, which we provide on a best-effort basis.

5. Health and safety

Lullo is not a medical device. It does not diagnose, treat or prevent any condition, and it does not watch or monitor a baby. Follow your doctor’s and your country’s safe sleep advice. Keep the phone away from the cot, keep the volume low and never use the app as a substitute for supervising a child.

6. Ads

The free version shows ads from Google AdMob. We do not choose individual ads and are not responsible for the products or sites they advertise. How ad data is handled is described in our Privacy Policy.

7. No warranty

The app is provided “as is” and “as available”. To the extent the law allows, we make no promises that it will be uninterrupted, error-free or suited to a particular purpose. Nothing in these terms limits rights you have as a consumer that cannot be limited by contract.

8. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential losses, or for loss of data, arising from your use of the app. Our total liability to you is limited to the amount you paid for the app and Premium.

9. Ending your use

You can stop using the app at any time by uninstalling it. We may end your licence if you break these terms.

10. Changes to these terms

We may update these terms when the app changes. We will post the new version on this page and update the date at the top. Continuing to use the app after a change means you accept the new terms.
