Privacy Policy

Last updated: August 6, 2026

1. Overview

This site (the "Site") is a collection of free online utility tools that can be used directly in your browser, with no installation required.

The Site itself has no backend server, so it does not collect or transmit to any server the memo/record data you enter into each tool. That data is stored only in your own browser (localStorage). However, the Site uses Google Analytics (GA4) to collect usage statistics; see Section 4 for details.

        Key summary: This site has no login or sign-up. Memos, records, and other data you enter into a tool are not sent to a server and are stored only in your browser. However, Google Analytics (GA4) collects some usage information via cookies for visitor statistics.
      

2. Information We Collect

This site collects the following information:

Browser local storage data — User input for each tool, such as notepad contents, calculator history, timer settings, D-Day lists, protein intake records/goals, team-divider presets, and roulette settings, is stored in localStorage on your device. This data is not transmitted to a server.
Theme setting — Your dark mode / light mode selection is stored in localStorage.
Visit statistics data (Google Analytics, GA4) — Usage statistics such as pages visited, time spent, and device/browser information are collected via Google Analytics. See Sections 4 and 6 for details.

The site operator does not directly collect personally identifiable information such as your name, email address, or payment information. See Sections 4 and 6 for the scope of information processed by Google Analytics.

3. Purpose of Use

Tool data stored in localStorage is used solely to preserve your user experience (e.g., restoring previous content when you close and reopen a page).

Visit statistics collected via Google Analytics are used solely to understand and improve service usage.

The site operator does not use this data for ad targeting or for sale to third parties. The Site currently has no advertising (e.g., Google AdSense) applied; if advertising is added in the future, this policy will be updated to reflect it.

4. Cookies and Tracking

This site uses Google Analytics (GA4, Measurement ID: G-23QGNEQT4R) to collect service usage statistics such as visitor counts, page views, and time spent. Cookies may be stored in your browser as part of this process.

If you do not want cookies stored, you can block cookies in your browser settings or use private/incognito mode. The specific handling of information collected by Google Analytics is governed by Google's Privacy Policy.

5. How to Delete Your Data

You can delete your localStorage data and cookies yourself by:

Browser settings → Privacy → Clear site data (including cookies)
Using the "Reset" or "Delete" button within each tool
Developer Tools → Application → localStorage, and deleting directly

6. Third-Party Services

This site uses the following third-party services:

Google Fonts (for loading fonts) — When font files are requested, some information, including your IP address, may be sent to Google.
Google Analytics (GA4) (for collecting visit statistics) — Collects visit data via cookies, and that data is transmitted to Google's servers.

For details on how each service processes information, please refer to Google's Privacy Policy.
