Terms of service

These terms govern your use of the Ferber app and the marketing site at ferberapp.com. By installing the app or using the site, you agree to these terms. We have written them in plain English where possible. Formal language appears only where it is required.

1. Who we are

Ferber is operated by Lucky Future Ltd, a private limited company registered in England and Wales (the "Company", "we", or "us"). Lucky Future Ltd trades as Pickled Pepper Studio. References to "you" mean the user of the app or the site.

2. The service

Ferber is an iPhone (iOS) application implementing the published Ferber sleep training method, plus a marketing and content website at ferberapp.com. The app provides:

  • An interval timer for the Ferber method.
  • Logging of check-ins and night history.
  • Night-by-night progress.
  • Bedtime reminders and interval check-in alerts.
  • Educational content about the method.

The website provides editorial content explaining the method and troubleshooting common situations.

3. Not medical advice

Ferber is educational software, not a medical device. The content of the app and the website is for general information only. It does not constitute medical advice and is not a substitute for consultation with a qualified healthcare professional. Do not start, modify, or stop sleep training based on this app alone if you have any concerns about your baby's health.

If your baby is unwell, in pain, or showing any symptoms that concern you, contact your pediatrician. The app's safety callouts are informational; they are not a substitute for medical judgement.

4. Eligibility and minimum age

The app is intended for use by adults (the parent or caregiver) for babies aged six months or older. The app's onboarding gates new arcs behind a six-month minimum. By using the app you confirm:

  • You are 18 years of age or older.
  • You are the parent or legal caregiver of the baby whose sleep is being trained, or you have permission from that parent or caregiver to use the app on their behalf.
  • Your baby is at least six months of age.

5. Price and payment

The app is free to download, and Night 1 of the program is free. Nights 2 to 7 are unlocked by a one-time, non-consumable in-app purchase called the Full 7-Night Program. The price is $29.99 in the United States; Apple sets the equivalent price in other countries, and the App Store shows you the exact price before you confirm.

  • It is a single payment, not a subscription. There is no free trial that converts to a charge, no recurring billing, no auto-renewal and nothing to cancel.
  • Payment is processed by Apple. Your purchase is also governed by Apple's standard terms for App Store purchases. We never see your card details.
  • Refunds for App Store purchases are handled by Apple, at reportaproblem.apple.com. We cannot issue App Store refunds directly. See the refunds support page.
  • We may change the price for future buyers. A price change does not affect a purchase you have already made.

6. Family Sharing and restoring purchases

The Full 7-Night Program supports Apple Family Sharing. If you share purchases with your Family Sharing group, members of that group can unlock the program on their own devices. If you reinstall the app or move to a new iPhone signed in with the same Apple ID, you can restore your purchase at no cost using Restore purchases on the unlock screen or in Settings.

7. Acceptable use

You agree not to:

  • Reverse-engineer, decompile, or attempt to extract source code from the app, except as allowed by law.
  • Resell, sublicense, or commercially redistribute the app or its content.
  • Use automated tools to scrape the website at a rate that materially burdens our servers.
  • Use the app or the website in violation of any applicable law.
  • Use the app or the website to harm, harass, or endanger any person.

8. Intellectual property

All software, design, and editorial content in the app and on the site is owned by Lucky Future Ltd or its licensors. The Ferber method itself is not owned by us; it is published by Dr. Richard Ferber, M.D. in Solve Your Child's Sleep Problems, available where books are sold. We are not affiliated with or endorsed by Dr. Ferber or Boston Children's Hospital.

You retain ownership of any data you enter into the app. Your night history, settings and your baby's name (if you add one) stay on your device; we do not have a copy and do not claim any rights in it. The limited anonymous analytics and crash data the app sends are described in our privacy policy. If you contact support, the email correspondence is retained per our privacy policy.

9. Third-party services

The app uses Apple (App Store, payments and notifications), RevenueCat (purchase management), PostHog (anonymous product analytics), Sentry (crash and error reports) and AppsFlyer (install attribution), as described in our privacy policy. The website uses Cloudflare for hosting and Cloudflare Web Analytics for aggregate measurement. Each third-party service has its own terms and privacy policy. We are not responsible for the third party's terms; we are responsible for our use of them.

10. Warranty disclaimer

The app and the website are provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation. Sleep training is a behavioural intervention, not a guaranteed outcome. We make no warranty that the app will produce a particular sleep result for your baby.

11. Limitation of liability

To the maximum extent permitted by law, our total liability to you for any claim arising out of or relating to the app or the website is limited to the greater of: (a) the amount you have paid to us in the 12 months before the claim, or (b) US$50.

We are not liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, or business interruption, even if we have been advised of the possibility of such damages.

Nothing in these terms excludes liability for death, personal injury caused by negligence, fraud, or any other liability that cannot be excluded by law.

12. Termination

You may stop using the app at any time by uninstalling it. We may suspend or terminate your access to the app or the website if you materially violate these terms, or if required to comply with law.

13. Changes to these terms

We may update these terms. Material changes will be notified through the app and on this page with an updated version number. Continued use of the app or the website after the effective date constitutes acceptance of the updated terms. If you do not accept the new terms, you may stop using and uninstall the app.

14. Governing law and jurisdiction

These terms are governed by the laws of England and Wales. Any dispute arising out of or relating to these terms or to the app will be subject to the exclusive jurisdiction of the courts of England and Wales, except where local consumer-protection law gives you the right to bring proceedings in another jurisdiction.
