Privacy Policy

We collect minimal information to provide our services. Here's what we collect and don't collect:

Technical Data: Browser type, operating system, screen resolution, device type, and general location (country/region level only)

Usage Analytics: Pages visited, time spent on pages, click patterns, and feature usage (all anonymized)

Preference Data: Theme settings (light/dark mode), accessibility preferences, and calculator favorites stored locally in your browser

We DO NOT collect: Names, email addresses, phone numbers, physical addresses, or any other personally identifiable information (PII)

We DO NOT store: Any data you enter into our calculators - all calculations are performed entirely in your browser

We DO NOT use: Tracking pixels, fingerprinting, or cross-site tracking technologies

We use the limited information we collect for specific, legitimate purposes:

Service Improvement: Understanding which calculators are most useful to optimize our offerings

Performance Optimization: Identifying and fixing technical issues, improving page load times

Usage Analytics: Aggregated, anonymous statistics to understand user behavior patterns

Security: Detecting and preventing malicious activity, spam, and abuse

Legal Compliance: Meeting our legal obligations when required by law

We never sell, rent, or share your information with third parties for marketing purposes.

We implement industry-standard security measures to protect your information:

Client-Side Processing: All calculations run locally in your browser - your data never leaves your device

HTTPS Encryption: All data transmission uses TLS 1.3 encryption with strong cipher suites

Security Headers: Strict Content Security Policy (CSP), X-Frame-Options, and other protective headers

Regular Audits: Periodic security reviews, vulnerability assessments, and penetration testing

Access Controls: Strict access controls and authentication for any administrative functions

No Data Storage: We don't store calculation inputs or results on our servers

We use cookies and local storage minimally and transparently:

Essential Cookies: Required for basic functionality (theme preference, accessibility settings)

Analytics Cookies: Anonymous usage statistics via Google Analytics (can be disabled)

Local Storage: Calculator history and favorites stored only in your browser

No Advertising Cookies: We do not use any advertising or remarketing cookies

No Third-Party Trackers: We don't allow third-party tracking cookies

You can manage cookies through your browser settings. Disabling essential cookies may affect site functionality.

We use select third-party services to operate our website:

Google Analytics: For anonymous usage statistics (privacy-focused configuration with IP anonymization)

Vercel: Our hosting provider for content delivery and edge functions

Cloudflare: CDN services for faster content delivery and DDoS protection

These providers are bound by their own privacy policies and data processing agreements. We've configured all services to minimize data collection and maximize user privacy.

Depending on your location, you may have specific privacy rights:

Right to Access: Request information about data we hold (note: we collect minimal data)

Right to Deletion: Request deletion of any data we may have about you

Right to Opt-Out: Disable analytics cookies through browser settings or our privacy controls

Right to Data Portability: Export your locally-stored preferences and favorites

Right to Non-Discrimination: We treat all users equally regardless of privacy choices

Since we don't collect personal data, most data rights are automatically fulfilled. For any requests, contact us via our contact page.

We are committed to compliance with major privacy regulations:

GDPR (European Union): We minimize data collection, provide transparency, and respect user rights under GDPR

CCPA (California): California residents have the right to know, delete, and opt-out. We do not sell personal information

LGPD (Brazil): We follow data minimization principles aligned with LGPD requirements

PIPEDA (Canada): Canadian users' privacy is protected under our minimal data collection practices

Our privacy-by-design approach means we collect so little data that compliance is built-in rather than retrofitted.

QuickCalc is designed to be safe for users of all ages:

We do not knowingly collect personal information from children under 13 (or applicable age in your jurisdiction)

Our calculators can be used by students and children without creating accounts or providing personal data

Parents and guardians: If you believe your child has provided personal information, please contact us

We comply with COPPA (Children's Online Privacy Protection Act) and similar international regulations

Our data retention practices reflect our minimal collection approach:

Analytics Data: Aggregated statistics are retained for up to 26 months, then automatically deleted

Server Logs: Technical logs are retained for 30 days for security purposes, then purged

Local Storage: Data stored in your browser remains until you clear it or uninstall

No Calculation Data: We don't store any calculation inputs or results - nothing to retain

QuickCalc is available globally with consistent privacy protections:

Data Processing: Our servers are located in multiple regions via our CDN for optimal performance

Cross-Border Transfers: Minimal anonymized analytics data may be processed in the United States

Regional Compliance: We respect and comply with privacy laws in your jurisdiction

Equal Protection: All users receive the same high level of privacy protection regardless of location

We may update this privacy policy from time to time:

Notification: Material changes will be announced via a notice on our website

Effective Date: Changes become effective on the date posted unless otherwise specified

Review: We encourage you to periodically review this policy for any updates
