Privacy Policy
Your privacy is important to us. Here's how we protect it.
Last updated: October 21, 2025
TL;DR - The Short Version
- We don't collect any personal information
- We don't use cookies or tracking scripts
- We don't sell or share any data (because we don't have any)
- Your calculations stay on your device
- We only see anonymous server logs (IP addresses, page views)
Information We Don't Collect
Chmod Calculator is designed with privacy in mind. We deliberately chose not to implement any tracking, analytics, or data collection mechanisms.
Personal Information
We don't collect names, email addresses, phone numbers, or any other personal identifiable information.
Usage Data
We don't track which chmod codes you calculate, how long you stay on the site, or what features you use.
Device Information
We don't collect information about your device, browser, operating system, or screen resolution.
Location Data
We don't track your location, IP address (beyond standard server logs), or geographic information.
Cookies and Local Storage
We use browser local storage (not cookies) to enhance your experience:
History
Your last 10 chmod calculations are stored locally on your device. This data never leaves your browser and is not sent to our servers.
Favorites
Chmod codes you star as favorites are stored locally on your device. This data is never transmitted or stored on our servers.
You can clear this local data at any time by clearing your browser's local storage or clicking the "Clear History" button in the calculator.
Server Logs
Like all websites, our hosting provider (Vercel) collects standard server logs:
- • IP addresses (anonymized)
- • Page URLs visited
- • Timestamps
- • HTTP status codes
- • Referrer information
These logs are used solely for technical purposes (debugging, security, performance) and are automatically deleted after 30 days. We don't analyze or use this data for marketing or tracking purposes.
Third-Party Services
