Privacy Policy

Last updated: March 2026

The short version

TimerBox doesn't collect your data. No accounts. No analytics cookies. No tracking pixels. Your timer settings and Pomodoro session history are stored in your browser's localStorage and never leave your device.

What we store

TimerBox stores the following data in your browser's localStorage:

  • Timer state (so a running countdown survives a page reload)
  • Pomodoro settings (work duration, break duration, cycle count)
  • Pomodoro session history (phase, duration, timestamp)
  • Interval timer settings (work duration, rest duration, rounds)
  • Meditation settings (duration, warmup, cooldown, interval bell, dim preference) and session count
  • Stream timer settings (duration, direction, message, font size, background, color)
  • Visual timer color and color phase preference
  • Breathing exercise pattern (inhale, hold, exhale, hold durations)
  • Theme preference (light or dark mode)
  • Sound preference

This data lives entirely in your browser. We never read it, transmit it, or store it on any server. Clearing your browser data removes it permanently.

Analytics

TimerBox uses Cloudflare Web Analytics to measure page performance (load times, core web vitals). This is privacy-first: no cookies, no personal data, no IP address tracking, no cross-site tracking. Cloudflare collects only anonymous performance timing metrics to help us understand how fast pages load. No individual visitors are identified or profiled.

TimerBox does not use Google Analytics, Facebook Pixel, or any behavioral tracking service. We don't track click events, user journeys, or individual behavior.

Cookies

TimerBox does not set any cookies.

Third-party services

The site is hosted on Cloudflare Pages. Cloudflare may collect standard web server logs (IP address, request URL, timestamp) as part of their infrastructure. This is governed by Cloudflare's privacy policy.

Fonts are loaded from Google Fonts. Google may collect standard request data when fonts are served. This is governed by Google's privacy policy.

Browser notifications

If you grant notification permission, TimerBox uses the browser's Notification API to alert you when a timer completes. This permission can be revoked at any time in your browser settings. No notification data is sent to any server.
