At Grade Calc Pro, we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website gradecalcpro.com and use our services.
Please read this Privacy Policy carefully. By using Grade Calc Pro, you agree to the terms of this Privacy Policy. If you do not agree with the terms of this Privacy Policy, please do not access or use our Service.
Our Privacy Commitment
Grade Calc Pro is built on a privacy-first foundation. We don’t require accounts, we don’t collect your grading data, and we don’t sell your information to third parties. Your privacy is not a feature we offer—it’s a fundamental principle of how we operate.
1. Information We Do NOT Collect
To be completely transparent, here’s what we explicitly DO NOT collect:
- Personal identification information (names, email addresses, phone numbers)
- Account information (we don’t have user accounts)
- Grading data (test scores, grades, student information)
- Location tracking (beyond general geographic region from IP)
- Browsing history across other websites
- Financial information (we’re completely free)
- Social media profiles or connections
- Device identifiers for tracking purposes
- Biometric data
- Any sensitive personal information
Your calculations stay on your device. When you enter test scores or grades into our calculator, that information is processed entirely in your web browser and is never transmitted to our servers.
2. Information We Collect Automatically
When you visit Grade Calc Pro, we may automatically collect certain technical information to help us maintain and improve our service:
2.1 Anonymous Usage Data
We use privacy-respecting analytics to understand how people use our service. This includes:
- Pages visited (which calculators you use)
- Time spent on the site
- Referring website (how you found us)
- Browser type and version
- Operating system
- Device type (mobile, tablet, desktop)
- General geographic location (country/region level, not precise location)
- Screen resolution and display settings
This data is collected in aggregate and anonymous form. We cannot identify individual users from this information.
2.2 Server Logs
Our web servers automatically record standard information including:
- IP addresses (anonymized and not linked to specific users)

- Pages requested

This information is used solely for:
- Maintaining server security
- Diagnosing technical problems
- Analyzing overall usage patterns
- Preventing abuse and detecting errors
Server logs are retained for a limited period and then automatically deleted.
2.3 Cookies and Local Storage
Grade Calc Pro uses minimal cookies and browser storage:
Essential Cookies: Used for basic site functionality, such as remembering your preferred settings (dark mode, grading scale preferences).
Analytics Cookies: Help us understand how visitors use our site through anonymous aggregated data.
Local Storage: Used to save your calculator preferences and custom grading scales on your device only. This data never leaves your browser.
You have full control: You can disable cookies through your browser settings. Note that disabling cookies may affect some features like saved preferences, but all calculators will continue to function.

3.4 Security and Compliance

4. Information Sharing and Disclosure
4.1 We Don’t Sell Your Data
Grade Calc Pro does not sell, rent, or trade any user information to third parties. Period.
4.2 Third-Party Service Providers
We may share anonymous, aggregated information with carefully selected service providers who help us operate our website:
Analytics Services: We may use privacy-focused analytics platforms (such as privacy-respecting alternatives to Google Analytics) that process data on our behalf under strict data protection agreements.
Hosting Providers: Our website is hosted by third-party services that may have access to server logs as part of providing hosting infrastructure.
CDN Services: We may use Content Delivery Networks (CDNs) to improve site speed and reliability.
All third-party providers are carefully vetted and required to:
- Protect data with appropriate security measures
- Use data only for providing their specific service
- Not use data for their own purposes
- Comply with applicable privacy laws
4.3 Legal Requirements
We may disclose information if required to do so by law or in response to:
- Valid legal processes (subpoenas, court orders)
- Government requests when legally obligated
- Protection of our rights, property, or safety
- Prevention of fraud or security threats
- Emergency situations involving danger to persons
We will resist overly broad requests and will notify users if legally permitted.
4.4 Business Transfers
In the unlikely event that Grade Calc Pro is acquired by or merged with another entity, user information may be transferred as part of that transaction. We would notify users of any such change and ensure the acquiring entity honors this Privacy Policy.
5. Data Security
5.1 Security Measures
We implement reasonable technical and organizational security measures to protect against unauthorized access, alteration, disclosure, or destruction of information:
- Secure connections: Our website uses HTTPS encryption
- Regular security audits: We monitor for vulnerabilities
- Access controls: Limited personnel access to systems
- Secure hosting: Industry-standard server security
- Regular updates: Software and security patches applied promptly
5.2 Local Processing
Because all grade calculations happen in your browser, your grading data never travels over the internet to our servers. This provides inherent security—data that’s never transmitted can’t be intercepted.
5.3 Limitations
However, no method of internet transmission or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security. You use the Service at your own risk.
6. Your Privacy Rights and Choices
6.1 Cookie Control
You can control cookies through your browser settings:

You can clear local storage (saved preferences) through your browser’s settings. This will remove any saved grading scales or preferences but will not affect the calculator’s functionality.
