Privacy Policy

Effective date: 10-13-2026

Calorie Deficit Calculator, available at caloriesdeficitcalculator.net, is operated by Elise Ava. This Privacy Policy explains how information may be processed when you visit our website, use our calculator, or contact us.

For privacy questions, contact info@caloriesdeficitcalculator.net

Calculator information

Our calculator uses details such as age, equation category, height, weight, activity level, selected deficit, and optional goal weight to generate estimates.

The calculator performs its calculations in your browser. Its code does not send these entered values to our server, maintain a server-side calculator history, or use them to create advertising audiences.

This does not mean that visiting the website involves no data processing. Hosting services, advertising providers, and other enabled website services may process technical information separately.

Your browser may also remember form entries according to its own settings.

Information you provide voluntarily

If you contact us by email or through an available contact form, we may receive your name, email address, message, and any other information you choose to provide.

We use this information to respond to your request, investigate reported problems, and manage related correspondence. Please avoid sending medical records or other unnecessary sensitive information.

Technical information

Our hosting and security services may process information such as:

  • IP address and browser type.
  • Device and operating-system information.
  • Pages requested and referring pages.
  • Request timestamps and security-related events.

This information may be used to operate the website, troubleshoot problems, prevent abuse, and maintain security.

If analytics tools are enabled, they may also collect usage information. Any such tools must be reflected in our privacy and consent disclosures.

Cookies and similar technologies

The website and its service providers may use cookies, local storage, web beacons, or similar technologies for essential website functions, consent preferences, analytics, and advertising, depending on which services are enabled.

Where required by applicable law, we request consent before using non-essential technologies.

You can manage cookies through your browser settings and, where available, through the website’s cookie settings control. Blocking certain technologies may affect website functionality.

Google AdSense and advertising

We may display advertisements through Google AdSense when advertising is enabled.

Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s advertising cookies enable Google and its partners to serve ads based on visits to this website and other websites on the Internet.

Advertising services may also use web beacons, IP addresses, and other identifiers to process information associated with ad delivery.

You can manage personalized advertising preferences through Google Ads Settings.

For more information, see How Google uses information from sites or apps that use its services.

If additional advertising providers are enabled, their identities and relevant privacy information will be disclosed through this policy or our consent-management disclosures.

We do not use calculator entries to select personalized advertisements.

Third-party resources

Our timeline chart may load a software library from cdnjs, a Cloudflare-hosted content delivery service.

Requesting that resource can disclose technical information, such as an IP address and browser request information, to the provider. The calculator code does not send entered body measurements with that request.

External websites and service providers have their own privacy practices. See the Cloudflare Privacy Policy for information about that provider.

Sharing and international processing

Technical information or correspondence may be processed by service providers that support hosting, security, communications, analytics, or advertising, where those services are used.

Information may also be disclosed when required by law or reasonably necessary to investigate abuse or protect legal rights.

Providers may process information in countries different from your own. Where applicable, appropriate contractual or other safeguards must be used for international processing.

Retention and security

We retain correspondence and technical records only for as long as reasonably necessary for their purposes, including responding to requests, resolving issues, maintaining security, and meeting legal obligations.

Advertising and other third-party providers apply their own retention practices.

We take reasonable steps to protect information, but no website, communication method, or storage system can guarantee absolute security.

Contact info@caloriesdeficitcalculator.net to make a request. We may need reasonable information to verify your identity.

Because the calculator does not maintain a server-side history of entered measurements, we cannot retrieve historical calculator entries that were not otherwise provided to us.

Children and teenagers

The website is primarily intended for adult educational use and is not directed to children under 15.

The calculator accepts inputs from age 15. For ages 15–17, it provides basic measurements only and does not apply adult calorie-deficit calculations or adult BMI classifications.

If you believe a child has provided personal information to us through correspondence, contact us so we can review the situation.

Changes to this policy

We may update this Privacy Policy as our services or legal requirements change. The revised policy will display an updated effective date.
