Terms and Conditions
Please review these terms before using BAC-CALC.COM and its estimation tools.
1. Agreement to Terms
By accessing or using BAC-CALC.COM (the "Website"), you agree to be bound by these Terms and Conditions ("Terms") and our Privacy Policy. If you disagree with any part of these Terms, you must not access or use the Website.
2. Educational & Mathematical Estimation Only
BAC-CALC.COM provides theoretical mathematical estimations based on published pharmacokinetic models (such as Widmark, 1932, and Watson et al., 1981). All calculations, charts, tables, and guides are presented strictly for educational and harm-reduction purposes.
The Website does not provide medical evaluations, clinical diagnoses, legal representation, or toxicological certification. Blood alcohol concentration (BAC) in living human bodies is subject to significant physiological variation that cannot be captured with certainty by any web application.
3. Vehicle Operation & Impairment Disclaimer
You agree never to rely on this Website, its calculators, or its generated data to determine whether you or anyone else should operate a motor vehicle, watercraft, aircraft, or machinery.
Any amount of alcohol consumption can cause significant cognitive, sensory, and motor impairment. Law enforcement authorities determine impairment through chemical evidence (breathalyzers, blood tests) and field sobriety evaluations. A mathematical calculation showing a low or zero blood alcohol figure does not protect against arrest, prosecution, accident, injury, or fatality.
Always arrange a designated sober driver, call a taxi, or use public transport or rideshare services whenever alcohol is consumed.
4. Client-Side Computing & User Privacy
BAC-CALC.COM is architected with a zero-tracking client-side model. All drink quantities, body weight inputs, gender selections, and timing data are computed entirely within your local browser JavaScript engine. We do not transmit, log, or store your alcohol consumption data on any remote server. For further details, consult our Privacy Policy.
5. Intellectual Property & Permitted Use
All site designs, layout styling, written articles, code implementations, and compilation of statutory datasets are the intellectual property of BAC-CALC.COM and are protected by applicable copyright and intellectual property laws.
You are granted a limited, revocable, non-exclusive license to use the Website for personal, non-commercial educational purposes. You may not scrape, mirror, repackage, or redistribute website assets without prior written authorization.
6. Disclaimer of Warranties
The Website and all materials, calculations, and content are provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, or mathematical precision. We make no warranty that the calculations will meet your individual requirements or that site operations will be uninterrupted or error-free.
7. Limitation of Liability
To the fullest extent permitted by applicable law, in no event shall BAC-CALC.COM, its authors, operators, contributors, or affiliates be liable for any direct, indirect, incidental, consequential, special, punitive, or exemplary damages—including but not limited to traffic violations, DUI/DWI convictions, legal penalties, personal injury, property damage, loss of license, or financial losses—arising out of or in connection with your use or inability to use this Website or reliance on any estimation provided herein.
8. Third-Party Links & Hotlines
The Website may include links to external resources, official government transport agencies (e.g., NHTSA, UK Department for Transport), and independent support hotlines (e.g., SAMHSA, UK Drinkline). These links are provided for educational and public health convenience; we do not control or endorse third-party content or services.
9. Corrections & Editorial Updates
We strive to maintain accurate statutory limits and scientific references. If you identify a statutory change or calculation error, please notify us via our Contact & Corrections page.
10. Modifications & Governing Law
We reserve the right to revise or replace these Terms at any time. Continued use of the Website following any changes constitutes acceptance of the new Terms. These Terms shall be construed and governed in accordance with applicable laws without regard to conflict of law principles.
