1. What Are Cookies?
Cookies are small text files that websites place on your computer, tablet, or mobile device when you visit them. They are widely used to make websites work properly, provide a smoother user experience, and supply reporting information to website operators and advertising networks.
In addition to standard HTTP cookies, websites may use related browser storage technologies such as HTML5 Local Storage and Session Storage.
2. How Mega Toolskit Uses Cookies & Local Storage
Mega Toolskit is intentionally built with a minimal tracking footprint. We categorise our use of cookies and local storage into the following types:
A. Strictly Necessary & Functional Local Storage
We use client-side HTML5 localStorage and sessionStorage to store your functional preferences locally on your device:
megatoolskit-theme: Preserves your visual mode preference (Light mode or Dark mode).megatoolskit_user_locale&megatoolskit_user_country: Stores your explicit language or region selection for localized calculators.mega_sci_calc_history_v1&mega_percentage_history: Stores your recent scientific and percentage calculator history locally in your browser so you can recall past calculations.megatoolskit_feedback_*: Stores your optional local tool star rating or comment on your device.chunk_reload_*(sessionStorage): Prevents infinite reload loops if a network interruption occurs while loading a tool module.
These entries reside entirely in your browser, are never transmitted to external servers, and can be inspected or cleared with one click on our Privacy Settings page.
B. Advertising Cookies (Google AdSense & Partners)
Mega Toolskit displays advertisements served by Google AdSense (Publisher ID: ca-pub-1745787826623696) and its certified advertising vendors. These advertising partners may set third-party cookies on your browser to:
- Serve ads that are relevant to your general interests based on prior browsing history.
- Limit the number of times you see a particular advertisement (frequency capping).
- Measure the effectiveness and reach of ad campaigns.
- Prevent fraudulent clicks and automated impressions.
C. Analytics Cookies (Google Analytics 4 & Google Tag Manager)
We use Google Analytics 4 (G-2QZ5KF8KYM) and Google Tag Manager (GTM-WLB6PMPB), which set standard first-party analytics cookies (such as _ga) to distinguish unique sessions and measure aggregate tool popularity. Our analytics implementation strictly strips out all personal inputs—never recording file names, file contents, passwords, or calculator numbers. You can opt out of analytics tracking on this browser at any time via our Privacy Settings page.
3. Third-Party Cookies & Google AdSense
Google, as a third-party vendor, uses cookies to serve ads on our site. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to Mega Toolskit and other sites on the Internet.
You may review Google's privacy practices regarding advertising by reading the Google Advertising Privacy FAQ.
4. How to Manage and Disable Cookies
You have full control over how cookies are stored on your device. Most web browsers allow you to modify your cookie settings at any time:
- Browser Settings: You can configure your browser (Chrome, Firefox, Safari, Edge) to block all cookies, accept only first-party cookies, or alert you when a cookie is being placed. Please note that disabling all cookies will not affect the functionality of client-side Mega Toolskit tools, but may affect ad display behavior.
- Google Ads Personalization: You can manage your personalized ad settings via Google Ads Settings.
- Industry Opt-Out Portals: You can opt out of interest-based advertising from participating companies via the Digital Advertising Alliance (DAA) or the European Interactive Digital Advertising Alliance (EDAA).
