Privacy Policy

1. Client-Side Computational Architecture (Our “Zero-Storage” Principle)

RuckingCalcs provides an extensive suite of interactive tactical calculation utilities, metabolic models (e.g., the Pandolf bioenergetics formula), spinal compression estimators, and mission pacing flight planners.

All numerical inputs—including but not limited to body weight, pack ballast, velocity, cadence, incline grade, and ambient temperatures—are processed entirely on the client side inside your local web browser using JavaScript.

• We do not transmit, log, record, or store your personal biometric inputs or calculation outputs on our web servers.
• Refreshing or closing your browser window instantly purges all user-entered calculator parameters from local memory.

2. Information We Automatically Collect

When you browse Ruck Gear Lab, our hosting infrastructure and integrated analytics services automatically collect standard technical log information, including:

• Device & Browser Telemetry: Browser type and version, operating system, device hardware model, screen resolution, and language settings.
• Network Information: Truncated/anonymized Internet Protocol (IP) addresses, approximate geographic location (country/city level), Internet Service Provider (ISP), and referring/exit pages.
• Interaction Telemetry: Timestamps, clickstream activity, navigation sequences, page load speeds, and bounce metrics.

3. Information You Voluntarily Provide

You are not required to create an account or provide identifying personal data to utilize our tools. However, if you choose to communicate with us directly via email at contact@ruckingcalcs.com, we collect your name, email address, message body, and any attachments you provide solely for the purpose of answering your inquiry, resolving technical issues, or incorporating feedback. We never sell, rent, or monetize your direct correspondence.

4. Cookies, Web Beacons & Tracking Technologies

Cookies are small text files stored on your device that help improve site stability, deliver relevant content, and analyze performance. We and our third-party vendors use the following cookie classifications:

• Strictly Necessary Cookies: Essential for foundational site operations, security filtering (e.g., Cloudflare DDoS defense), and caching.
• Analytical / Performance Cookies: Gather aggregated, non-identifying telemetry (e.g., via Google Analytics 4) to help us understand which calculators are most utilized and how to optimize user experience.
• Advertising & Targeting Cookies: Deployed by ad networks (such as Google AdSense) to deliver contextual and personalized advertisements based on browsing behavior across the web.

You can control or disable cookie tracking at any time through your web browser preferences or via our on-site cookie consent banner. Note that disabling cookies will not impede the functionality of our client-side calculators.

5. Third-Party Advertising & Monitization (Google AdSense)

We may display third-party advertisements served by Google AdSense and its certified advertising partners. Google uses cookies (including the DoubleClick cookie) to serve ads based on your prior visits to our website or other websites across the internet.

• Users in certain jurisdictions (including the EEA, UK, and California) can opt out of personalized advertising by visiting Google Ads Settings or through the Digital Advertising Alliance Consumer Choice tool.
• Google’s use of advertising cookies is governed by the Google Privacy & Terms Policy.

6. Affiliate Programs & Commercial Partnerships (Amazon Associates)

RuckingCalcs is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com and affiliated international storefronts.

When you click an outbound affiliate link on our site and complete a purchase, Amazon uses cookies and pixel trackers to authenticate the referral and credit our account with a small commission at no additional cost to you. These interactions are governed directly by Amazon’s Privacy Notice.

7. Legal Bases for Processing Under GDPR (EEA & UK Users)

If you reside within the European Economic Area (EEA) or the United Kingdom, our legal grounds for collecting and processing your technical information include:

• Legitimate Interests: Operating, diagnosing, and securing our digital infrastructure and delivering accurate algorithmic tools.
• Consent: Storing non-essential cookies and serving personalized advertising where explicit consent is granted via our consent management platform (CMP).
• Legal Obligations: Compliance with statutory tax, regulatory, or security reporting standards.

8. Your Privacy Rights (GDPR & CCPA/CPRA)

Depending on your geographic location, you possess statutory rights regarding your personal data:

• Right of Access & Portability: Request confirmation of whether we process your data and obtain an exported copy.
• Right to Rectification: Request correction of inaccurate or incomplete personal records.
• Right to Erasure (“Right to Be Forgotten”): Request permanent deletion of correspondence or personally identifiable data held by us.
• Right to Restrict or Object to Processing: Challenge our legitimate interest processing or revoke cookie consent.
• “Do Not Sell or Share My Personal Information” (CCPA): We do not sell user personal information. You can opt out of cross-context behavioral advertising through our cookie consent module.

To exercise any of these statutory rights, submit a verifiable request to contact@ruckingcalcs.com. We will verify and fulfill your request within 30 days without discrimination.

9. Data Retention & Security Standards

Server log files and aggregated analytics are retained for a limited duration (typically 14 months) before automatic purge or irreversibly aggregated anonymization. Direct email correspondence is retained only as long as necessary to address your inquiry or maintain compliance records.

We enforce strict security protocols across our infrastructure, including modern Transport Layer Security (TLS 1.3 encryption), automated Web Application Firewalls (WAF), and routine vulnerability patching. However, no internet transmission is 100% invulnerable; we advise caution when transmitting sensitive data over public connections.

10. Children’s Online Privacy Protection (COPPA Compliance)

RuckingCalcs is intended solely for adult fitness enthusiasts, military service members, and tactical athletes. We do not knowingly target, solicit, or collect personal information from children under the age of 13 (or under 16 in the EEA/UK). If you believe a minor has provided us with personal information, contact us immediately at contact@ruckingscalcs.com for prompt removal.

11. Updates to This Privacy Policy

We reserve the right to revise this Privacy Policy periodically to reflect changes in regulatory standards, computational infrastructure, or commercial relationships. Any modifications will be posted directly to this URL with an updated “Effective Date” at the top of the document. We recommend reviewing this page periodically.
