Privacy Policy.
Last updated: June 12, 2026
Overview
Study Timer is a client-side web application. We are committed to protecting your privacy. This policy explains how we handle information when you use our service at freestudytimer.online.
TL;DR — All your data stays in your browser. We don't collect, store, or transmit any personal information to external servers.
Data We Collect
Study Timer does not collect any personal data. The application runs entirely in your browser. All settings, tasks, statistics, and preferences are stored locally using your browser's localStorage API.
Local Storage
We use browser localStorage to persist your preferences and session data. This data never leaves your device. The following keys are used:
| Key | Purpose |
|---|---|
| study-timer-settings | Timer durations, sound, theme preferences |
| study-timer-tasks | Your task list and progress |
| study-timer-stats | Focus time, pomodoro count, streak |
| study-timer-active-task-id | Currently selected task |
You can clear all stored data at any time through the Settings panel → "Clear All System Data" button.
Third-Party Services
Study Timer loads fonts from Google Fonts (Inter and JetBrains Mono). Google may collect anonymized usage data as described in their Privacy Policy. No other third-party services are used.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. Continued use of the application after changes constitutes acceptance of the new policy.
