Privacy Policy

Information we collect

• Basic usage data (e.g., pages viewed, referral source) to understand what content is helpful and what needs improvement.
• Technical data (e.g., device type, browser, approximate location derived from IP) for performance, debugging, and security.
• Cookie or local storage identifiers that help the site function and measure usage (if enabled by your browser and consent settings).
• Aggregated interaction signals (e.g., button clicks, scroll depth) to improve navigation and page structure.
• Error logs (e.g., page load failures) that may include technical context needed to fix bugs and improve reliability.
• Advertising-related signals (where applicable), such as ad impressions, to support the free operation of the site.
• Basic performance measurements (e.g., load time, latency) so we can keep pages fast and reliable.
• Approximate, aggregated audience insights (e.g., top countries) to understand where usage is coming from at a high level.
• Security-related signals (e.g., suspicious request patterns) used to rate-limit abuse and protect uptime.
• Contact information only if you choose to send it to us (for example, an email address in a support message).
• We do not intentionally collect sensitive personal data through the calculators. Please avoid entering sensitive information into any text fields or messages.
• If a third-party ad or analytics provider is used, that provider may collect identifiers and usage data according to its own policy and consent mechanisms.
• If you click outbound links, the destination site may receive referral information according to standard browser behavior.
• We may retain aggregated, anonymized statistics (for example, total page views) that do not identify you personally.

How we use information

• To run and maintain the site and its features (including calculators, pages, and performance optimizations).
• To improve content quality and user experience (for example, clarifying confusing sections or improving page speed).
• To measure site usage at an aggregate level so we can prioritize updates and new tools responsibly.
• To prevent abuse, fraud, and automated misuse, and to keep the site secure.
• To comply with applicable legal obligations where required.
• To diagnose incidents and outages and to restore service quickly when something breaks.
• To understand which pages users find valuable so we can maintain them and remove low-value clutter.
• To ensure ads (if shown) are delivered and measured in a way that supports site operations.
• To respond to support requests you initiate (for example, answering privacy questions).
• To enforce site integrity rules (rate limits, anti-bot protections) that protect availability for all users.
• To keep documentation accurate by learning which definitions and examples users find confusing.

Third-party services

We may use third-party services such as analytics, hosting/CDN, and advertising providers. These services may collect information according to their own policies and may set cookies or similar identifiers. In many cases, the third party acts as an independent controller for its own data processing. We recommend reviewing the privacy policies of any third-party providers you interact with through this site. We do not control how third parties use data once it is collected under their policies, and your rights and choices may depend on the third party and your jurisdiction. If you want to opt out of a specific provider, the most direct path is usually the provider’s own opt-out controls.

Your choices

• You can disable cookies in your browser settings (some features may not work as intended).
• You can use privacy-focused browser modes or content blockers; this may reduce analytics accuracy and some ad delivery.
• You can stop using the site at any time.
• If your jurisdiction provides rights to access, delete, or correct personal data, you can contact us to request help.
• You can avoid sharing personal information in any messages you send to us (for example, don’t include credentials or sensitive details).
• You can review and manage device-level permissions and settings that may affect analytics or advertising identifiers.
• You can clear site storage (cookies/local storage) at any time using your browser settings.
• If you use a shared device, consider signing out of any accounts in your browser and clearing storage to reduce unintended tracking.
• If you believe a third-party provider is collecting data you don’t want to share, review that provider’s opt-out mechanisms.
• If you want maximum privacy, consider using a browser with strict tracking protection and limiting third-party cookies.
• If you contact us, you can ask what data we may have received through your message and request deletion where applicable.
• If you are in a jurisdiction with additional privacy rights, those rights may apply depending on the nature of the data and the provider involved.

Contact

Contact us if you have questions about privacy or data use. Include a brief description of your concern and the page or feature you are referring to so we can respond efficiently. If you are requesting access or deletion, describe what information you believe you provided (for example, an email used in a message) so we can locate it.
