Terms of Service
These Terms of Service ("Terms") govern your use of Alcometer.org. By using the site you agree to these Terms. If you do not agree, please stop using the site.
1. Nature of the service
Alcometer.org is a free, non-commercial, educational website operated by Piotr Zieminski as a natural person. No goods or services are offered for sale. No user account is provided. The content is strictly informational.
2. Educational and informational use only
All content on Alcometer.org — including the blood-alcohol calculator, legal-limit tables, hangover guidance, recovery content, and body-impact narrative — is provided for educational and informational purposes only. It is not, and must not be treated as:
• medical advice;
• legal counsel;
• a substitute for an official calibrated evidential breath or blood test;
• a certification of fitness to drive, work, or perform any other activity requiring unimpaired attention.
If you need medical advice, consult a physician or qualified addiction specialist. If you need legal advice, consult a lawyer admitted to practice in the relevant jurisdiction.
3. No forensic, evidential, or enforcement use
You may not introduce Alcometer outputs — including screenshots, downloaded JSON, or quoted numbers — as evidence in any court, tribunal, licensing hearing, workplace proceeding, or insurance dispute. The tools are not calibrated, not chain-of-custody certified, and not a substitute for statutory breath, blood, or urine testing.
Employers, insurers, and public authorities must not treat the site as an official record of alcohol absence or impairment. Any enforcement or safety decision requires methods that comply with the law applicable to that decision.
4. No warranty
The site is provided "as is" and "as available", without any warranty of any kind, whether express, implied, statutory, or otherwise — to the fullest extent permitted by applicable law. The operator does not warrant that the site will be uninterrupted, error-free, or that the numerical estimates are accurate for any particular individual. Individual variation in alcohol pharmacokinetics (absorption, distribution, elimination) can be substantial and is discussed on the Methodology page.
5. Limitation of liability
To the fullest extent permitted by applicable law, the operator — as a natural person acting in a non-commercial capacity — excludes all liability for any direct, indirect, incidental, special, consequential, or exemplary damages arising out of or in connection with the use of, or inability to use, Alcometer.org. This includes, without limitation, loss of profits, goodwill, data, or other intangible losses resulting from any decision taken on the basis of the calculator output.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for gross negligence, wilful misconduct, and personal injury or death caused by the operator's gross negligence under art. 415 and 471 of the Polish Civil Code (Kodeks cywilny) and equivalent mandatory consumer-protection provisions.
6. Your responsibilities
You agree not to rely on Alcometer.org to decide whether you are ready to make a driving decision, operate machinery, perform safety-critical work, or make any decision for which an objective, calibrated, contemporaneous measurement of alcohol absence or impairment is legally or practically required. Decisions about driving after drinking are yours alone; when in doubt, do not drive.
You also agree not to use the site in any way that is unlawful, that attempts to disrupt its normal operation, or that infringes the intellectual-property rights of the operator or third parties.
7. Intellectual property
All text, layout, graphics, and software on Alcometer.org are protected by copyright, database rights, and related intellectual-property rights, owned by or licensed to the operator. You may view and print content for personal, non-commercial use. Redistribution, republication, or commercial exploitation requires the operator's prior written consent.
Source code and data that are explicitly released under an open-source licence (where applicable) are governed by the terms of that licence.
8. Third-party links
Alcometer.org may contain links to third-party websites (government publications, academic sources, news articles). These are provided for convenience only and do not constitute an endorsement. The operator has no control over third-party sites and accepts no liability for their content.
9. Changes to the service and these Terms
The operator may update, modify, or discontinue parts of the site at any time, with or without notice. These Terms may be revised; the "last updated" date above indicates the current version. Continued use after publication of a revised version constitutes acceptance of the new Terms.
10. Governing law, jurisdiction, and mandatory consumer rights
These Terms are governed by the laws of the Republic of Poland, without regard to conflict-of-laws principles. Subject to mandatory consumer-protection laws of your habitual residence, any dispute arising in connection with these Terms shall be submitted to the competent ordinary courts of Poland.
Consumers resident in the European Union retain the benefit of the protective provisions of the law of their country of habitual residence under Art. 6 of Regulation (EC) No. 593/2008 (Rome I). If you are in the EEA, you may use the European Commission’s Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr/ for information about out-of-court dispute resolution; participation is voluntary and does not replace your statutory rights.
If you are in the United Kingdom, the Consumer Rights Act 2015 and the Consumer Protection from Unfair Trading Regulations 2008 (among other instruments) may give you remedies for unfair terms and misleading practices that cannot be contractually waived.
If you are in the United States, state consumer-protection laws vary. States such as California, New York, Florida, and Texas (without limitation) provide non-waivable statutory remedies; state attorneys general and the Federal Trade Commission enforce unfair-or-deceptive-practices statutes independently of these Terms. Nothing above limits any mandatory consumer right in your home jurisdiction.
