Cookie Policy

1. Cookies We Use

PercentileCalculator.us uses three types of cookies:

2. Essential Cookies

These cookies are strictly necessary for our website to function properly. They enable basic features like:

• Remembering which calculator tab you’re currently using (Salary, Income, Test Scores, or Statistics)
• Maintaining your session as you navigate between pages
• Storing temporary calculation preferences

What Essential Cookies Do NOT Do

• Store or transmit your calculator inputs (salary, income, test scores)
• Track your browsing behavior
• Share data with third parties
• Identify you personally

3. Analytics Cookies (Google Analytics)

We use Google Analytics to understand how visitors interact with our percentile calculators. These cookies collect anonymous information such as:

• Page views: Which pages you visit and how long you spend on them
• Calculator usage: Which calculator types are most popular (Salary, Income, Test Scores, Statistics)
• Traffic sources: How you found our website (search engines, direct visits, referrals)
• Device information: Browser type, operating system, screen resolution
• Geographic data: Approximate location (city/state level, not precise GPS)
• User behavior: Navigation patterns, bounce rates, session duration

What Google Analytics Does NOT Collect

How We Use Analytics Data

We use this anonymous data to:

• Understand which calculators are most useful to visitors
• Identify and fix technical issues or bugs
• Improve website performance and load times
• Make informed decisions about new features or calculators to add
• Optimize the user interface for better usability

Opt Out of Google Analytics

You can prevent Google Analytics from tracking you by:

• Installing the Google Analytics Opt-out Browser Add-on
• Enabling “Do Not Track” in your browser settings
• Blocking analytics cookies through your browser settings (see Section 6)

4. Advertising Cookies (Google AdSense)

We display advertisements through Google AdSense to support free access to our calculators. These advertising cookies are used to:

• Show relevant ads: Display advertisements that may be of interest to you based on your browsing history
• Frequency capping: Limit how many times you see the same advertisement
• Measure effectiveness: Track whether ads were viewed or clicked
• Prevent fraud: Detect and prevent invalid ad clicks or impressions

How Google AdSense Cookies Work

Google and its advertising partners may use cookies to:

• Serve ads based on your prior visits to our website or other websites
• Serve ads based on your interests (interest-based advertising)
• Track ad performance and attribution
• Build advertising profiles (for personalized ads)

Third-Party Advertising Partners

Google AdSense works with various advertising partners who may also set cookies. These partners include ad networks, demand-side platforms, and data management platforms that help deliver relevant advertisements.

Opt Out of Personalized Advertising

You can control personalized advertising through:

• Google Ads Settings: Manage your ad preferences
• Network Advertising Initiative: Opt out of participating networks
• Digital Advertising Alliance: Consumer choice tool
• Your Online Choices (EU): European opt-out tool

Note: Opting out of personalized ads does NOT mean you’ll see fewer ads—you’ll still see the same number of advertisements, but they may be less relevant to your interests.

5. First-Party vs. Third-Party Cookies

First-Party Cookies (Set by PercentileCalculator.us)

These are cookies we set directly:

• Essential functionality cookies (remembering your selected calculator tab)
• Session management cookies

First-party cookies only work on our website and cannot track you across other sites.

Third-Party Cookies (Set by External Services)

These are cookies set by services we use:

• Google Analytics: Tracks anonymous usage statistics across our site
• Google AdSense: Delivers and measures advertisements
• Google Fonts: Loads custom typography (minimal data collection)

Third-party cookies may track your activity across multiple websites you visit.

6. How to Manage and Delete Cookies

You have several options to control or delete cookies:

Browser Settings

All modern browsers allow you to manage cookies through their settings. Here’s how:

• Google Chrome: Settings → Privacy and security → Cookies and other site data
• Mozilla Firefox: Settings → Privacy & Security → Cookies and Site Data
• Safari: Preferences → Privacy → Manage Website Data
• Microsoft Edge: Settings → Cookies and site permissions → Manage and delete cookies

Cookie Management Options

You can choose to:

• Block all cookies: Prevents all websites from setting cookies (may break website functionality)
• Block third-party cookies: Allows our site to function while blocking tracking cookies from other sites
• Delete existing cookies: Removes all currently stored cookies from your device
• Allow only essential cookies: Blocks analytics and advertising cookies while keeping necessary functionality cookies

Mobile Device Settings

• iOS (iPhone/iPad): Settings → Safari → Block All Cookies or Prevent Cross-Site Tracking
• Android: Chrome app → Settings → Site settings → Cookies

Impact of Blocking Cookies

7. Do Not Track (DNT) Signals

Some browsers offer a “Do Not Track” (DNT) signal that requests websites not to track your browsing activity.

Current Status: There is no universal standard for how websites should respond to DNT signals. Our current implementation:

• We respect browser-level cookie blocking (see Section 6)
• We do not alter our tracking behavior based on DNT signals alone
• You can use the opt-out links in Sections 3 and 4 to prevent tracking

Regardless of DNT settings, we never collect your calculator input values (salary, income, test scores). These remain private in your browser.

8. California Privacy Rights (CCPA)

If you are a California resident, you have specific rights under the California Consumer Privacy Act (CCPA):

Right to Know

You have the right to know what cookies and tracking technologies we use. This Cookie Policy provides that information.

Right to Opt-Out of Sale

We do not sell your personal information. While we use Google AdSense, which displays personalized ads, this does not constitute a “sale” under CCPA definitions.

Right to Delete

You can delete cookies at any time through your browser settings (see Section 6).

Right to Non-Discrimination

We will not discriminate against you for exercising your CCPA rights. You can delete cookies or opt out of tracking without losing access to our calculators.

California Residents: For additional privacy rights, see our Privacy Policy or email contact@percentilecalculator.us

9. European Privacy Rights (GDPR)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, you have rights under the General Data Protection Regulation (GDPR):

Legal Basis for Cookies

• Essential cookies: Necessary for website functionality (legitimate interest)
• Analytics cookies: Based on your consent (cookie banner acceptance)
• Advertising cookies: Based on your consent (cookie banner acceptance)

Your Rights

• Right to withdraw consent for non-essential cookies
• Right to access data collected through cookies

EU Residents: For complete GDPR rights and information, see our Privacy Policy

10. Children’s Privacy

Our website is not directed at children under 13, and we do not knowingly collect personal information from children through cookies or any other means.

If a parent or guardian becomes aware that their child has provided us with information through cookies, please contact us at contact@percentilecalculator.us, and we will delete such information.

Students may use our test score percentile calculator for educational purposes, but since our calculators don’t store input values and essential cookies don’t collect personal information, no child data is collected.

11. Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our cookie usage, legal requirements, or business practices.

When we make changes:

• We will update the “Last Updated” date at the top of this page
• Material changes may be communicated through a notice on our homepage
• Your continued use of our website after changes constitutes acceptance

We encourage you to review this Cookie Policy periodically to stay informed about how we use cookies.
