Privacy Policy

Welcome to Percentage Calculator (www.easypercentage-calculator.com). This Privacy Policy explains how we collect, use, and protect information when you use our free online percentage calculation tools, including our Discount Calculator, VAT Calculator, Tax Calculator, Subject Percentage Calculator, GPA to Percentage Calculator, and GST Calculator.

We believe privacy is a fundamental right. Our tools are built with a privacy-first philosophy — our calculators are entirely client-side, meaning all calculations happen in your web browser and no computation data is ever transmitted to or stored on our servers.

We collect the absolute minimum data necessary to operate our service. Here's exactly what we may collect:

Information you voluntarily provide:

• Your name, email address, and message when you submit our contact form
• Any feedback, suggestions, or bug reports you send us directly

Information collected automatically:

• IP address (anonymized) — collected briefly by our hosting infrastructure for security purposes
• Browser type and version — used to ensure compatibility
• Device type (mobile, desktop, tablet) — used for responsive design analytics
• Pages visited and time spent — collected via analytics tools to improve our tools
• Referring URLs — to understand how users find us

What we do NOT collect:

• Calculation inputs or results (all processing is done locally in your browser)
• Financial, health, or sensitive personal data
• Payment information of any kind (our service is 100% free)
• Social media account data or login credentials

Any information we collect is used strictly for the following purposes:

• Responding to your inquiries — contact form submissions are used only to reply to you
• Improving our tools — aggregate, anonymized analytics help us understand which calculators are most useful and identify bugs
• Website security — server logs help us detect and prevent malicious activity, DDoS attacks, and unauthorized access
• Legal compliance — retaining records as required by applicable law

We do not use your information for advertising profiling, sell it to data brokers, or share it with any third party for marketing purposes.

We use cookies and similar technologies to provide a better user experience. Here's what we use and why:

Essential Cookies

• Required for basic site functionality (e.g., language preference, session state)
• Cannot be disabled without breaking site functionality
• No personal data stored

Analytics Cookies

• Used to measure site traffic and understand user behavior in aggregate
• Data is anonymized — we cannot identify individual users
• May use services such as Google Analytics or a privacy-friendly alternative

We do not use advertising cookies, tracking pixels, or any retargeting technologies.

Calculator Data: All calculations performed using Percentage Calculator's tools — whether you're computing a discount, VAT, tax, subject marks, GPA, or GST — are processed entirely within your browser. This data never leaves your device and is never transmitted to our servers.

Contact Form Data: Messages submitted through our contact form are transmitted over an encrypted HTTPS connection and stored securely. We retain contact inquiries for up to 12 months unless you request deletion.

Security Measures We Implement:

• HTTPS encryption on all pages
• Regular security audits of our codebase
• Principle of least privilege — only key team members can access stored contact data
• No storage of sensitive financial data whatsoever

Percentage Calculator may integrate with or link to the following types of third-party services:

• Hosting Providers — Our site is hosted on infrastructure that may process your IP address for routing and security purposes
• Analytics Platforms — Aggregate, anonymized traffic data to help us improve the site
• Content Delivery Networks (CDN) — Used to serve assets faster; CDNs may log IP addresses temporarily

Our site may contain links to external websites (e.g., educational resources, financial regulators). Clicking these links takes you outside of Percentage Calculator. We have no control over the privacy practices of external sites and are not responsible for their content or policies. We recommend reviewing the privacy policy of any site you visit.

We do not integrate with social media advertising platforms or allow third-party behavioral advertising on our site.

Percentage Calculator is a general-audience website and our percentage calculators are widely used by students of all ages. However, our contact form and any data collection features are directed to users who are 13 years of age or older (or the minimum age required by applicable law in your jurisdiction).

We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has submitted personal information to us, please contact us immediately at hello@easypercentage-calculator.com and we will promptly delete that information from our records.

• No account creation required — students can use all tools without providing any personal data
• No behavioral tracking of individual users
• No advertising targeted at children

Depending on your location, you may have the following rights regarding your personal data:

• Right to Access — Request a copy of the personal data we hold about you
• Right to Rectification — Request correction of inaccurate personal data
• Right to Erasure — Request deletion of your personal data ("right to be forgotten")
• Right to Restrict Processing — Request that we limit how we use your data

Percentage Calculator is available in 18 languages and serves users across the globe. By using our service from outside the country where our servers are located, you understand that your information may be transferred across international borders.

We take appropriate measures to ensure that any cross-border data transfers are handled in accordance with applicable data protection laws, including:

• Standard Contractual Clauses (SCCs) for EU/EEA data transfers
• Adequacy decisions where applicable
• Minimizing data collection to reduce transfer risk
