Terms of Use

Last updated: August 8, 2026

1. Agreement to these terms

By accessing or using Sibling Stack (the "Service"), you agree to be bound by these Terms of Use. If you do not agree, please do not use the Service. These terms apply to all visitors, registered users, and anyone else who accesses the Service.

2. Description of the Service

Sibling Stack is a baby and toddler schedule tracking tool and content site designed for parents and caregivers of children who are close in age. Core tracking features are provided free of charge. Premium features may be introduced at a later date, governed by additional terms at that time.

3. Eligibility

You must be at least 18 years old to create an account and use the Service. By creating an account, you represent that you meet this age requirement and that any information you provide is accurate and complete.

4. Your account

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to notify us immediately if you suspect unauthorised use of your account. We are not liable for any loss or damage arising from your failure to keep your credentials secure.

5. Acceptable use

You agree not to:

  • Use the Service for any unlawful purpose or in violation of any applicable law or regulation.
  • Upload or transmit any content that is harmful, offensive, defamatory, or infringes any third-party rights.
  • Attempt to gain unauthorised access to any part of the Service, other users' accounts, or any system or network connected to the Service.
  • Interfere with or disrupt the integrity or performance of the Service.
  • Use automated means to scrape, harvest, or collect content or data from the Service without prior written consent.

6. Children's data

Sibling Stack is used by parents and caregivers — not directly by children. When you enter a child's name or date of birth into the Service, you represent that you are that child's parent or legal guardian, or that you have the authority to enter such information on behalf of the child's parent or legal guardian. You are responsible for the accuracy of all information you enter.

7. Affiliate links and third-party content

Some articles on this site contain affiliate links. As an Amazon Associate and participant in other affiliate programmes, we may earn a commission from qualifying purchases made through those links at no additional cost to you. Affiliate relationships do not influence our editorial recommendations. Third-party websites linked from the Service are governed by their own terms and privacy policies; we are not responsible for their content or practices.

8. Intellectual property

All content on the Service — including text, graphics, code, and design — is owned by or licensed to Sibling Stack and is protected by applicable intellectual property laws. You may not reproduce, distribute, or create derivative works from any content on the Service without our prior written consent, except for personal, non-commercial use.

9. User content

You retain ownership of any data you enter into the Service (your tracking logs, notes, and household information). By using the Service, you grant us a limited licence to store and process that data solely for the purpose of providing the Service to you. We do not claim ownership of your data and will not use it for any purpose beyond operating and improving the Service, as described in our Privacy Policy.

10. Disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, express or implied. We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components.

Nothing on Sibling Stack constitutes medical, clinical, or professional advice. Content about infant and toddler care, feeding, sleep, and development is for general informational purposes only. Always consult a qualified healthcare provider for advice specific to your child's health and development.

11. Limitation of liability

To the maximum extent permitted by applicable law, Sibling Stack and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, revenue, or profits, arising out of or in connection with your use of the Service, even if we have been advised of the possibility of such damages.

12. Indemnification

You agree to indemnify and hold harmless Sibling Stack and its operators from any claims, losses, damages, or expenses (including reasonable legal fees) arising from your use of the Service, your violation of these Terms, or your violation of any third-party rights.

13. Changes to these terms

We may update these Terms of Use from time to time. When we do, we will update the "last updated" date at the top of this page. Continued use of the Service after changes are posted constitutes your acceptance of the revised Terms. For material changes, we will make reasonable efforts to notify registered users by email.

14. Termination

We reserve the right to suspend or terminate your account at our discretion, with or without notice, for any violation of these Terms or for any other reason we consider appropriate. You may close your account at any time by contacting us at the address below.

15. Governing law

These Terms are governed by applicable law. Any disputes will be resolved through good-faith negotiation in the first instance. If unresolved, disputes will be subject to the jurisdiction of the courts applicable to the operator's place of business.
