Privacy Policy

Our Privacy Commitment

DateMath Pro is built with privacy as a core principle. All date calculations happen entirely in your browser using JavaScript. We never see, store, or transmit your dates to our servers.

What We Collect

Nothing by default. Your calculations stay in your browser.

• Calculation History: Stored locally in your browser's IndexedDB. Never sent to our servers.
• User Preferences: Stored in your browser's localStorage. Includes settings like date format preferences.
• Analytics: We use privacy-friendly analytics to understand how people use the site (page views, popular features). No personal data is collected.

Data Retention

All your data stays in your browser:

• Calculation history: Automatically cleared after 90 days of inactivity
• You can manually clear your history at any time using the "Clear History" button
• Clearing your browser data will remove all DateMath Pro data

Third-Party Services

We use minimal third-party services:

• Vercel: Hosting and performance analytics
• Ahrefs: Privacy-friendly web analytics
• Google Fonts: Typography (no tracking cookies)

Your Rights

Since we don't collect personal data, there's nothing to request, delete, or export from our side. All your data is already under your control in your browser.
