Privacy Policy — K-Drama Culture Guide

Last updated: April 13, 2026

K-Drama Culture Guide (“the Extension”) is a Chrome browser extension that helps international K-drama fans understand Korean cultural elements using AI-powered explanations.

This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

Data We Collect

1. Anonymous User ID (UUID)

When you install the Extension, a random unique identifier (UUID) is generated and stored locally on your device. This ID is used solely to manage your daily free question limit (5 questions per day). It is not linked to your name, email, or any personal information.

2. Questions You Ask

When you submit a question through the Extension, the question text is sent to our server to generate a response. We log the question text for service improvement purposes (identifying popular topics to improve our built-in glossary). Question logs are stored with only the first 4 characters of your UUID for aggregate analysis — they cannot be traced back to you individually.

3. Cached Responses

Previously answered questions and their responses are cached on our server to provide faster answers and reduce costs. Cached data contains only the question-answer pair with no user-identifying information.

Data We Do NOT Collect

No personal information: We do not collect your name, email address, phone number, or any personally identifiable information.
No browsing history: The Extension does not access, read, or track the websites you visit. It has no permissions to read page content.
No account required: You do not need to create an account to use the Extension.
No cookies or tracking: We do not use cookies, analytics trackers, or advertising pixels.

Data Retention

Data Type	Retention Period
Usage count (daily question limit)	2 days
Question logs	90 days
Cached responses	30 days
Local UUID	Stored on your device until you uninstall the Extension

All server-side data is automatically deleted after the retention period expires.

Third-Party Services

Anthropic Claude API

When you ask a question that is not answered by the built-in glossary or server cache, your question is sent to the Anthropic Claude API to generate a response. Anthropic’s privacy policy applies to this processing. Your question is sent without any personal identifiers. For more information, see Anthropic’s Privacy Policy.

Cloudflare

Our server runs on Cloudflare Workers. Cloudflare may process standard connection metadata (IP address, request headers) as part of its infrastructure services. For more information, see Cloudflare’s Privacy Policy.

Data Storage and Security

Your UUID and settings are stored locally on your device using Chrome’s built-in storage API (chrome.storage.local).
Server-side data is stored on Cloudflare’s globally distributed infrastructure with encryption at rest.
API keys are stored securely as server environment variables and are never exposed to the client.

Your Rights

Uninstall: Uninstalling the Extension removes all locally stored data (UUID, settings) from your device.
Daily reset: Your usage count resets automatically every day at midnight UTC.
No account to delete: Since we don’t collect personal information or require accounts, there is no account to delete.

Children’s Privacy

The Extension is not directed at children under 13. We do not knowingly collect information from children under 13.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the “Last updated” date at the top of this page.
