Privacy Policy

BAC Calculator is designed to deliver blood alcohol content estimations while collecting as little personal information as possible. This Privacy Policy explains what data is involved, how it is processed, and the controls available to you.

By accessing or using the service you acknowledge that you have read and understood this policy. If you do not agree, please discontinue use of the site.

We only gather information that is essential to operate, secure, and improve the calculator:

• Calculator inputs you choose to enter (gender, weight, beverage details, timing). These values stay within your current browsing session and are cleared when you close or refresh.
• Non-identifying usage metrics such as page views, device type, language preference, and approximate region collected through privacy-focused analytics.
• Support communications or feedback you voluntarily send us, which may include contact information.

All BAC computations occur locally in your browser using in-memory variables. We do not transmit your calculator inputs to our servers for storage or profiling.

We never build persistent user profiles, link calculator results to identities, or retain historical BAC calculations.

We use a minimal cookie footprint to keep the site functional and understand aggregated usage trends:

• Essential cookies to remember language preferences and maintain secure sessions.
• First-party analytics cookies that capture anonymized, aggregated statistics to help us improve usability.
• No advertising networks, cross-site tracking pixels, or behavioral targeting cookies are deployed.
• You can disable cookies via browser controls, although certain preferences may no longer persist.

We rely on carefully vetted service providers to host and deliver the website. These partners may process limited technical metadata on infrastructure located in the United States or other jurisdictions.

Each provider is contractually required to implement security and privacy safeguards comparable to ours.

• Cloud hosting platforms and content delivery networks that store static assets and serve pages securely.
• Performance and error-monitoring tools configured without personal identifiers to maintain service reliability.
• Analytics platforms that receive aggregated usage statistics without identifiers that could directly identify you.

Calculator inputs are erased when your session ends; we do not keep them beyond your active visit.

Support messages or optional contact records are retained only for the time needed to respond and to meet legal or compliance obligations, after which they are securely deleted or anonymized.

We implement administrative, technical, and physical safeguards including HTTPS encryption, principle-of-least-privilege access controls, and periodic security reviews to protect any data in our care.

Despite our efforts, no online service can guarantee absolute security. You share information at your own risk.

Depending on your jurisdiction, you may have legal rights regarding your personal information. We will honor valid requests to the extent required by applicable law.

• Request confirmation of whether we process any of your personal data and receive a copy if available.
• Ask us to correct, delete, or restrict the processing of information you previously provided.
• Opt out of analytics by adjusting cookie settings or using built-in browser privacy tools.
• Submit privacy questions or complaints using the contact methods listed below.

The service is intended for adults of legal drinking age. We do not knowingly collect information from anyone under the age permitted to consume alcohol in their jurisdiction. If we learn that we have received data from a minor, we will delete it promptly.

We may revise this Privacy Policy to reflect product updates, legal requirements, or best practices. Material changes will be highlighted on this page and the "Last updated" date below will be revised accordingly.
