クッキーポリシー
最終更新日: 2025年6月
1. What Are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, or smartphone) when you visit a website. They allow the website to recognize your device and store certain information about your preferences or past actions. Along with cookies, web technologies like localStorage and sessionStorage allow websites to save client-side configuration parameters to improve loading speed and user experience.
2. How We Use Cookies & Local Storage
Tip Calculator Pro uses cookies and local browser storage to provide a fast, personalized, and seamless experience. Our tools calculate gratuities and bill splits locally in your browser. We use client-side storage for the following specific purposes:
- Essential Site Operation: Ensuring fast load times, responsive UI rendering, and asset delivery.
- User Preferences: Storing your display preferences (such as Dark Mode / Light Mode) and selected language so you do not have to reconfigure them on every visit.
- Cookie Consent: Remembering whether you have acknowledged our cookie consent notice so the banner does not reappear repeatedly.
- Performance & Analytics: Aggregating anonymous traffic patterns and tool usage to help us improve calculation features and site navigation.
3. Categories of Cookies We Use
A. Strictly Necessary & Functional Storage
These items are essential for the website to function correctly. Without these technologies, key features like saving your selected theme or remembering your cookie consent cannot operate.
| Storage Name | Type | Purpose | Duration |
|---|---|---|---|
| tipCalcTheme | Local Storage | Stores Dark/Light mode preference | Persistent |
| tipcalc_cookie_consent | Local Storage | Remembers cookie consent acknowledgement | Persistent |
B. Analytics & Performance
We may use privacy-respecting analytics tools to collect anonymous statistics, such as page visits, referring websites, and average interaction duration. This data contains no personally identifiable information and is used strictly to enhance our website performance and tool accuracy.
C. Third-Party Services
We may utilize trusted third-party providers for content delivery networks (CDNs), web typography (e.g., Google Fonts), and security scanning. These providers may set technical cookies required for secure network transmission.
4. Zero Tracking of Financial Data
All math calculations (bill amount, tip percentages, tax amounts, and group splits) are computed locally inside your browser via JavaScript. We do not transmit, log, or store your private receipts or financial numbers on any remote servers.
5. Managing and Disabling Cookies
You have full control over cookie settings in your web browser. You can configure your browser to reject cookies, alert you before receiving a cookie, or delete existing cookies at any time:
- Google Chrome: Settings > Privacy and Security > Cookies and other site data
- Apple Safari: Preferences > Privacy > Block all cookies
- Mozilla Firefox: Settings > Privacy & Security > Cookies and Site Data
- Microsoft Edge: Settings > Cookies and site permissions > Manage and delete cookies
Please note that disabling local storage or blocking essential cookies may cause your dark mode preference or language settings to reset to defaults upon refreshing.
6. Updates to This Cookie Policy
We may periodically update this Cookie Policy to reflect technical, legal, or operational changes. Any modifications will be published directly on this page with an updated revision date.
