1. What Are Cookies & Browser Local Storage?

Cookies are small text files placed on your computer or mobile device by websites you visit. They are widely used to make websites work efficiently, remember user preferences, or provide analytics and advertising measurement.

Browser Local Storage (localStorage) is a modern web browser feature that allows a website to store small pieces of preference data directly inside your browser on your device. Unlike traditional HTTP cookies, data stored in localStorage is not automatically transmitted to the server with every webpage request.

2. How UnitConvertersGo Uses Browser Storage Today

We designed UnitConvertersGo to minimize data collection. Rather than setting tracking cookies or storing your preferences on a remote server, our calculators use your browser's local storage solely for functional user-interface preferences:

Preference Storage: Remembering whether you prefer the Light or Dark color theme.
On-Device Convenience: Keeping a short list of your most recent unit conversions and any converter pairs you choose to bookmark on your device.

If you block cookies or clear local storage in your browser, all unit conversion calculators on UnitConvertersGo will continue to calculate results normally; only your saved theme preference and recent/bookmarked lists will reset.

3. Exact Browser Storage Keys Used on This Site

We do not invent or hide storage identifiers. Below is the complete list of client-side storage keys used by the UnitConvertersGo application:

Key Name	Storage Type	Category	Purpose & Duration
theme	localStorage	Preference	Stores `"light"` or `"dark"` when you toggle the display theme in the header. Kept in your browser until you clear site data.
ucg_recent_conversions	localStorage	Functional	Stores up to your most recent unit conversion calculations on your device so you can quickly reference them on converter pages. Never transmitted to our servers. Kept until you click “Clear” or clear browser storage.
ucg_favorite_conversions	localStorage	Functional	Stores unit conversion pairs you bookmark on converter pages for fast access on your device. Never transmitted to our servers. Kept until you remove the bookmark or clear browser storage.

4. Analytics & Advertising Cookies Status

Current Status: No Third-Party Analytics or Advertising Cookies Are Active

Currently, third-party analytics and advertising integrations (such as Google Analytics and Google AdSense) are disabled on UnitConvertersGo. We do not currently set analytics cookies or advertising cookies when you visit our pages.

Future Updates & Consent Requirements: If we integrate analytics or advertising services (such as Google AdSense) in the future to support the website, we will update this Cookie Policy with the specific cookie categories, providers, and durations before or upon launch. Where consent is legally required for visitors in specific jurisdictions (such as the EEA, UK, or Switzerland), a compliant consent management mechanism will be deployed rather than relying solely on a policy page.

6. Controlling Cookies & Site Data in Your Web Browser

In addition to the on-page tool above, every modern web browser lets you inspect, block, or delete cookies and localStorage data through its built-in privacy settings:

Google Chrome / Microsoft Edge: Open Settings → Privacy and security → Third-party cookies / Site settings → View permissions and data stored across sites.
Mozilla Firefox: Open Settings → Privacy & Security → Cookies and Site Data → Manage Data.
Apple Safari (macOS / iOS): Open Settings (or Preferences) → Privacy → Manage Website Data.
