Privacy Policy
Last updated: November 2025
Overview
At UnitsConversion.io, we are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights regarding your information.
Data We Do NOT Collect
All unit conversions happen entirely in your browser. We never send your conversion inputs or results to any server. Your calculations are completely private.
- We do not collect or store the values you convert
- We do not track which specific conversions you perform
- We do not require any account or registration
- We do not sell any user data
Local Storage
We use your browser's localStorage to save:
- Cookie preferences: Your consent choices for analytics
- Recent conversions: A history of your recent conversion types (not values) for convenience
This data never leaves your device and can be cleared at any time through your browser settings.
Analytics (With Your Consent)
If you accept analytics cookies, we use Google Analytics 4 to understand how visitors use our site. This helps us improve the service. We have configured Google Analytics with:
- IP Anonymization: Your full IP address is never stored
- Consent-based: Analytics only runs after you accept cookies
Cookies We Use
| Cookie | Type | Purpose | Duration |
|---|---|---|---|
| cookie-consent | Necessary (localStorage) | Stores your cookie preferences | Permanent |
| _ga | Analytics | Distinguishes unique users | 2 years |
| _ga_* | Analytics | Maintains session state | 2 years |
Your Cookie Choices
When you first visit our site, you can choose to:
- Accept All: Enable analytics to help us improve
- Reject All: Only necessary cookies (localStorage for preferences)
- Customize: Choose which types of cookies to allow
You can change your preferences at any time by clearing your browser's localStorage and refreshing the page.
GDPR Rights (EU Users)
If you are in the European Union, you have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data
- Object to processing of your data
- Data portability
Since we don't collect personal data beyond anonymous analytics (with consent), these rights are largely already satisfied by design.
CCPA Rights (California Users)
California residents have the right to:
- Know what personal information is collected
- Know if personal information is sold or disclosed
- Say no to the sale of personal information
- Access their personal information
- Equal service and price, even if they exercise their privacy rights
We do not sell personal information. The only data we collect (with consent) is anonymous analytics data.

We may update this policy occasionally. We will post any changes on this page with an updated revision date.
