1. Introduction

Welcome to ko.fm's Privacy Policy. This policy explains how we collect, use, and protect your personal information when you use our URL shortening service.

2. Information We Handle

When you use ko.fm or the ko.fm browser extension, we handle only the information needed to provide and protect the URL shortening service:

• The URL you explicitly choose or enter for shortening, including a current-page or hyperlink URL selected through the extension
• The resulting short URL and its creation time
• Technical request information such as IP address, browser type and version, and date and time of access

3. Browser Extension Data

The browser extension sends a URL to https://ko.fm over HTTPS only after you request that it be shortened. The URL is used to create or return the corresponding ko.fm short link.

The extension stores up to 20 recent items—original URL, short URL, and creation time—in chrome.storage.local on your device. This history is not synchronized through Chrome Sync. You can delete individual items or clear the entire history from the extension.

4. How We Use Your Information

We use the collected information to:

• Provide and maintain our URL shortening service
• Analyze usage patterns to improve our service
• Prevent abuse of our service

We do not sell extension user data or use it for personalized advertising, creditworthiness, or lending purposes.

5. Retention and Data Security

Shortened URLs are retained while the shortening service continues to provide the requested link. Extension history remains only in the browser's local storage until you remove it, clear the extension data, or uninstall the extension. Technical request records may be retained as reasonably needed for security, abuse prevention, and service reliability.

We use HTTPS for extension-to-service communication and implement appropriate technical and organizational measures to protect information against unauthorized or unlawful processing, accidental loss, destruction, or damage.

6. Your Rights

You have the right to:

• Access the personal information we hold about you
• Request correction of your personal information
• Request deletion of your personal information
• Object to processing of your personal information

7. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
