Terms of Service

1. Acceptance

By accessing or using this site, you agree to these Terms. If you don't agree, please don't use the site. The Operator may update these Terms without prior notice; updated Terms take effect when posted, with the "Last updated" date reflecting the change.

2. What the site provides

The site provides:

• Web-based calculators, converters and shared group scheduling
• Guides and reading material that may differ by language, plus related app experiences

No account or login is required, and all tools and content are free to use. We make best efforts to keep the site available but do not guarantee 100% uptime.

3. Disclaimer — Information and Education Only

Calculator results and editorial content are provided for information and educational reference only and are not a substitute for:

• Medical diagnosis, prescription, or treatment advice. The BMI/BMR/TDEE and pregnancy-week tools are not medical advice. Please consult a qualified physician, pharmacist, or other licensed medical professional for health-related decisions.
• Legal advice. Information about laws on age, pregnancy, or finance reflects the situation at the time of writing and may change. For legally binding decisions, please consult a licensed attorney.
• Financial or tax advice. Interest and tax calculations follow general formulas and don't reflect every individual situation (dependents, deductions, contract terms, jurisdiction). For real financial or tax decisions, consult a CPA, financial planner, or qualified institution.

To the maximum extent permitted by law, the Operator is not liable for direct or indirect damages caused by errors in calculator output, lack of precision, or unincorporated changes to applicable law. This limitation does not apply to damages caused by the Operator's intentional misconduct or gross negligence.

4. Advertising

Ads may be enabled on selected content in the future, and availability may differ by page. Advertising does not mean the Operator endorses or guarantees a third-party product or service shown in an ad.

We will disclose sponsorship or affiliate relationships when such content is published. For cookies on pages where ads are enabled, see the Privacy Policy.

5. Intellectual Property

All content on the site (text, images, code, design, the PiPi mascot) is owned by the Operator (PiFl Labs) or its licensors. The following actions require separate written permission:

• Reproducing or republishing entire articles or large blocks of text
• Extracting or redistributing tool source code
• Commercial use of the PiPi mascot
• Commercial translation or republication

Short excerpts with attribution (URL or site name) are permitted. Non-commercial personal quoting is broadly allowed.

External sources cited on the site (laws, professional society guidelines, government statistics, journal articles) remain the property of their respective rights holders. Their use may be subject to additional restrictions; please check the original source.

6. User Obligations

When using the site, please:

• Do not use the site for any unlawful purpose or in violation of public policy.
• Do not attempt to disrupt site stability through automated requests, scraping, or denial-of-service activity.
• Do not rely on calculator output as the sole basis for medical, legal, or financial decisions.
• Do not submit content (in feedback or email) that infringes the rights of the Operator or other parties.
• Do not republish multiple body paragraphs without attribution.

7. External Links

The site contains links to external websites (government agencies, professional societies, statistics, Wikipedia, etc.). The Operator is not responsible for the content, accuracy, terms, or privacy practices of those external sites. Please review the linked site's own policies when you follow an external link.

8. Changes to Service

The Operator may modify the tools, content, or design, or temporarily or permanently suspend the service, at its discretion. Where possible we provide advance notice, but urgent security or legal reasons may require immediate change without notice.

9. Governing Law and Disputes

These Terms and any dispute related to the use of the site are governed by the laws of the Republic of Korea. In the event of a dispute, please first contact the Operator by email (support@pifl-labs.com) so we can attempt to resolve the matter through good-faith discussion. If amicable resolution is not reached, the courts of the Operator's jurisdiction shall serve as the agreed first-instance forum.
