What Are Cookies
Cookies are small text files placed on your device when you visit a website. They serve various functions including enabling core website features, remembering your preferences, and providing analytics data to website operators.
Cookies may be "first-party" (set by the website you are visiting) or "third-party" (set by external services integrated into the website). Some cookies are "session cookies" that are automatically deleted when you close your browser, while "persistent cookies" remain on your device until they expire or are manually removed.
In addition to traditional cookies, we use localStorage in your browser to save your theme preference (dark/light mode). Unlike cookies, localStorage data is not transmitted to our servers with each request.
Essential Cookies & Local Storage
These are necessary for core website functionality:
- 345tool_theme — Local storage entry that remembers your dark mode or light mode preference. This never leaves your browser and is not a traditional cookie.
- Session Cookie (PHPSESSID) — Used by our server to maintain your login session after Google OAuth authentication. Deleted when you close your browser.
Analytics Cookies (Google Analytics)
We use Google Analytics 4 to understand aggregate website usage patterns:
- _ga — Distinguishes unique users. Expires after 2 years.
- _ga_* — Session-specific identifier for Google Analytics 4. Expires after 2 years.
Google Analytics collects anonymized, aggregate data. Individual visitors are not personally identified. To opt out of Google Analytics tracking, install the Google Analytics Opt-out Browser Add-on.
Advertising Cookies (Google AdSense)
We display advertisements through Google AdSense to support the free operation of our website. AdSense may use cookies and similar technologies to serve relevant ads and measure ad performance:
- __gads — Tracks ad views and user interaction with ads. Expires after 13 months.
- __gpi — Google Publisher Infrastructure cookie for ad delivery. Expires after 13 months.
Google may use your browsing history across websites to personalize ads. You can manage ad personalization in Google Ads Settings or opt out via the Digital Advertising Alliance.
Managing Your Cookie Preferences
Most web browsers allow you to control cookies through their settings. You can typically:
- View all cookies stored by websites you have visited.
- Delete individual cookies or clear all stored cookies.
- Block third-party cookies or all cookies by default.
- Configure your browser to notify you when a website attempts to set a cookie.
