Welcome to IntermittentFastingCalculators.com (“we,” “our,” or “us”). We respect your privacy and are deeply committed to protecting the information you may provide while using our website and online interactive calculation tools.
This Privacy Policy explains what information we collect, how we use it, how we safeguard it, and your legal rights and choices when you visit and interact with IntermittentFastingCalculators.com (the “Website”). By accessing or using our Website, you acknowledge and agree to the practices described in this Privacy Policy.
Document Navigation Summary
1. Information We Collect
Our core engineering philosophy is to keep our tools frictionless, universally accessible, and anonymous—without mandating that visitors create accounts, login, or provide personal identity information to compute schedules.
Depending on your interactions with the Website, we categorize collected data as follows:
A. Information You Voluntarily Provide
Most calculators operate independently of personal profiles. When you input variables into tools such as:
- Age, biological sex, height, and current body weight
- Physical activity frequency and daily exertion intensity
- Fasting protocol preferences (e.g., 16:8, 18:6, OMAD)
- Target feeding, eating, or wake/bedtime hours
- Baseline water consumption and sweat hydration factors
- Caloric deficit goals and macronutrient distribution percentages
This numerical information is processed exclusively by the calculator scripts to generate your immediate result. We do not intentionally collect, store, or sell this input data as personally identifiable information.
B. Automatically Collected Technical Data
When navigating our digital infrastructure, standard diagnostic telemetry may be captured by server logs, security suites, and analytics providers, including:
- Internet Protocol (IP) address and approximate geographic location (city/country level)
- Browser type, language settings, and client version
- Operating system, screen resolution, and hardware device category
- Referring URL, entrance/exit timestamps, and clickstream interaction telemetry
- Server diagnostics, latency logs, and automated bot-filtering security events
2. Calculator Data Privacy & Client-Side Execution
Client-Side Processing Architecture
The calculations on IntermittentFastingCalculators.com (including timer countdowns, macro distributions, and hydration quotas) are performed locally inside your browser’s JavaScript sandbox. This means your personal metrics (such as weight or sleep hours) are processed in real-time on your device and are not stored in database records on our servers.
We strongly urge all visitors not to enter real names, phone numbers, or private medical records into calculator forms, as our utilities require solely numerical values to calculate outputs.
3. How We Use Collected Information
We process information strictly for legitimate operational purposes, including:
- Providing, calculating, maintaining, and enhancing our interactive fasting and wellness utilities
- Analyzing aggregate user trends to optimize algorithm performance and UI accessibility
- Hardening cyber defense against brute-force attacks, scraper bots, and malicious requests
- Diagnosing technical server errors, latency spikes, and browser compatibility issues
- Fulfilling legal obligations, anti-fraud verifications, and regulatory audit mandates
4. Cookies and Similar Tracking Technologies
IntermittentFastingCalculators.com uses small text files known as cookies, along with browser web storage (such as localStorage for preserving active fasting timer sessions across page reloads).
These technologies are deployed for:
- Essential Security & Session Tokens: Verifying CSRF tokens to block malicious cross-site submissions.
- User Preference Persistence: Remembering metric vs. imperial measurement preferences.
- Performance & Analytics Measurement: Measuring site speed, bounce rate, and high-traffic pages.
- Monetization & Advertising: Serving contextual ad inventory where permitted.
You maintain full authority to reject or delete cookies via your browser preferences. Note that disabling essential cookies may impact interactive timer storage or UI layouts.
5. Third-Party Web Analytics
We may integrate privacy-respecting analytics services (such as Google Analytics 4) to evaluate macro visitor patterns, session durations, and mobile responsiveness. These analytical providers aggregate telemetry anonymously without linking browsing logs to real-world identities.
6. Advertising Networks & Monetization
To keep our suite of calculators 100% free for global visitors, we display advertisements provided by certified third-party ad networks (such as Google AdSense or Adsterra).
These advertising vendors may utilize cookies, web beacons, or tracking pixels to display contextual or non-intrusive ads based on previous visits to this and other internet domains. You can opt-out of personalized interest-based advertising via Google Ad Settings or the Digital Advertising Alliance (DAA).
7. Third-Party Infrastructure & External Links
Our digital delivery involves trusted cloud partners for content delivery network (CDN) acceleration, DDoS mitigation, and server hosting. While our articles frequently reference authoritative scientific sources (such as the National Institutes of Health or New England Journal of Medicine), we are not responsible for the privacy practices, content, or cookie tracking of external third-party websites.
9. Data Retention & Cybersecurity Protocols
Server security logs are retained only as long as necessary to enforce firewall safeguards, audit error codes, and fulfill legal compliance. We employ technical and organizational security controls—including HTTP Strict Transport Security (HSTS), 256-bit SSL encryption, Content Security Policies (CSP), and automated rate-limiters—to prevent unauthorized data exposure.
11. Children’s Online Privacy Protection
Our Website and health calculators are not designed for or targeted at children under the age of 13. We do not knowingly solicit or collect personal identifiable information from children under 13 years of age. If you believe a minor has submitted personal data through our site, please contact us immediately to purge such records.
12. Health and Medical Disclaimer
Mandatory Informational Disclaimer
The algorithms, outputs, and written resources published on IntermittentFastingCalculators.com are provided strictly for general educational and informational purposes. They do not constitute formal medical diagnoses, clinical advice, personalized dietary prescriptions, or therapy.
Prolonged water fasting, aggressive caloric restriction, and abrupt metabolic shifts can trigger physiological complications in individuals with underlying conditions, pregnant/nursing mothers, or those taking prescription pharmaceuticals. Always consult a licensed physician or registered dietitian before initiating any fasting regimen.
13. Your Privacy Rights (GDPR, CCPA & Global Regimes)
Depending on your jurisdiction (such as California under the CCPA/CPRA, or the European Economic Area / UK under the GDPR), you hold legal statutory rights regarding your digital data:
- Right to Know & Access: The right to request confirmation regarding what information is processed.
- Right to Erasure & Deletion: The right to request the purging of personal identifiers.
- Right to Object & Opt-Out: The right to opt-out of personal data sharing or non-essential ad profiling. We confirm that we do not sell your personal data for financial compensation.
