Terms of Service

Last updated: April 2026

By using DueDateLab you agree to these terms. They're short. Please read them.

The service

DueDateLab provides free informational calculators and editorial content. The service is offered "as is" without warranties of any kind. We do our best to keep calculations accurate, but we do not guarantee the absence of errors.

Not medical advice

Nothing on DueDateLab is medical, legal, or financial advice. See the Disclaimer for full language.

Your responsibilities

  • Use the site only for lawful purposes.
  • Do not scrape, republish, or resell the content without written permission.
  • Do not attempt to disrupt the service or probe its security.

Intellectual property

All content, code, design, and trademarks on DueDateLab are the property of DueDateLab or their respective owners. You may share links freely; you may not copy substantial portions without permission.

Third-party content

The site links to third-party resources and displays third-party advertising. We do not endorse and are not responsible for the content of external sites.

Limitation of liability

To the fullest extent permitted by law, DueDateLab and its operators are not liable for any direct, indirect, incidental, or consequential damages arising from your use of the site or reliance on any calculation.

Indemnification

You agree to indemnify and hold harmless DueDateLab and its operators from any claim, liability, loss, or expense (including reasonable legal fees) arising from your misuse of the site, your violation of these terms, or your infringement of any third-party right. This clause survives termination of your use of the site.

Eligibility and age

DueDateLab is intended for users who are at least 16 years old. By using the site you confirm that you meet this minimum age. We do not knowingly collect data from anyone under 13, and users under 16 in jurisdictions that require parental consent for online services should use the site only with permission from a parent or guardian.

Governing law and jurisdiction

These terms are governed by the laws of Belgium, without regard to conflict-of-law principles. Any dispute arising from or relating to these terms or your use of DueDateLab will be brought exclusively before the competent Belgian courts. This does not affect mandatory consumer-protection rights you may have under the law of your country of residence.

Severability

If any provision of these terms is found to be invalid or unenforceable, the remaining provisions will remain in full force and effect, and the invalid provision will be replaced with a valid one that most closely reflects the original intent.

Changes

We may update these terms. The "Last updated" date at the top reflects the current version. Material changes will be noted on the homepage.
