Privacy Policy for Curio

Last Updated: 2025-12-29

Introduction

Curio ("we," "our," or "the Extension") is a Chrome browser extension that enables users to capture, organize, and search web content locally on their device. This Privacy Policy explains how we handle your data when you use Curio.

Our Core Privacy Principle: All data collected by Curio is stored exclusively on your device. We do not transmit, sell, or share your data with any third parties.

Data Collection

What Data We Collect

Curio collects website content when you explicitly choose to save it. This includes:

Text content from web pages you select and save
Images from web pages you capture
Webpage metadata such as titles, descriptions, publication dates, and Open Graph tags
Hyperlinks associated with saved content
User-created content such as tags, notes, and whiteboard arrangements

What Data We Do NOT Collect

Curio does not collect:

Personally identifiable information (name, address, email, etc.)
Health information
Financial or payment information
Authentication credentials (passwords, PINs, etc.)
Personal communications (emails, messages, etc.)
Location data (GPS, IP address, etc.)
Web browsing history (beyond content you explicitly save)
User activity data (clicks, keystrokes, scroll position, etc.)

How We Use Your Data

All collected website content is used solely for the Extension's single purpose: enabling you to build and manage your personal knowledge base. Specifically, we use your data to:

Store captured snippets and web pages for later viewing
Enable search functionality (full-text and semantic search)
Organize content in whiteboards, timelines, and lists
Display saved content within the Extension interface
Process content locally for AI-powered features (when enabled)

Data Storage

Local Storage Only

All data collected by Curio is stored locally on your device using IndexedDB, a browser-based database. This means:

Your data never leaves your device
No cloud servers are involved
No external databases store your information
The Extension works completely offline

Data Retention

Your saved content remains on your device until you:

Manually delete it through the Extension interface
Uninstall the Extension (which removes all stored data)
Clear your browser's IndexedDB storage

No Data Transmission

Curio does not transmit any data outside your browser. Specifically:

❌ No data is sent to external servers
❌ No data is shared with third parties
❌ No data is sold or monetized
❌ No analytics or tracking services are used
❌ No cloud synchronization occurs

We do not sell, transfer, or share your data with any third parties, except as required by law or to comply with legal obligations.

Permissions Explained

Curio requests the following permissions, all of which are necessary for core functionality:

contextMenus

Creates right-click menu options ("Save to Curio" and "Save this page") to enable quick content capture.

storage

Saves captured content locally in IndexedDB on your device.

activeTab

Accesses the active tab's content only when you explicitly trigger a save action (via context menu or keyboard shortcut).

Host Permissions (`<all_urls>`)

Allows the Extension to inject content scripts on any webpage you visit, enabling content capture functionality. Content is only accessed when you explicitly choose to save it.

Remote Code

Curio does not use remote code. All JavaScript and WebAssembly code is bundled directly in the Extension package. We do not:

Load external JavaScript files
Use dynamic imports from external sources
Execute code via eval() with external strings
Load WebAssembly modules from external sources

Your Rights and Control

Access and Deletion

You have complete control over your data:

View your data: All saved content is accessible through the Extension interface
Delete your data: Remove individual items or clear all data through the Extension interface
Export your data: Use the built-in export feature to download your data as JSON
Uninstall: Removing the Extension deletes all stored data from your device

Data Portability

You can export all your saved content as JSON at any time using the Extension's export feature. This allows you to:

Create backups of your data
Migrate to another device
Use your data with other tools

Security

Local Security

Your data is protected by:

Browser-level security (IndexedDB isolation)
No network transmission (eliminates interception risks)
Local-only processing (no external attack surfaces)

Best Practices

While Curio stores data locally, you should:

Keep your browser updated
Use secure browsing practices
Be cautious when saving sensitive content

Children's Privacy

Curio is not intended for children under 13. We do not knowingly collect data from children. If you believe we have collected data from a child, please contact us immediately.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by:

Updating the "Last Updated" date at the top of this policy
Posting a notice in the Extension (if significant changes occur)

Your continued use of Curio after changes become effective constitutes acceptance of the updated policy.

Compliance

This Privacy Policy complies with:

Chrome Web Store Developer Program Policies
General data protection principles
User privacy expectations
