Privacy Policy

Introduction

Shelf is a bookmark management service that helps you save, organize, and search your bookmarks using semantic search. This privacy policy explains what data we collect, how we use it, and your rights regarding your information.

Data We Collect

Account Information

When you create an account, we collect your email address for authentication and account management. This information is required to provide you with access to your bookmarks.

Bookmark Data

We store the bookmarks you save, including:

URLs of web pages you bookmark
Page titles, descriptions, and metadata (automatically fetched)
Images and site names from bookmarked pages
Notes you add to bookmarks
Tags you assign to organize bookmarks
Timestamps of when bookmarks were created and last visited

Embeddings for Search

To enable semantic search functionality, we generate vector embeddings from your bookmark content (titles, descriptions, notes). These embeddings are stored in our database and used solely to power search within your bookmarks.

How We Use Your Data

We use your data exclusively to provide and improve the Shelf service:

Storing and organizing your bookmarks
Enabling semantic search across your bookmarks
Providing access to your bookmarks across devices
Managing your account and authentication
Improving service functionality and performance

We do not sell, rent, or share your data with third parties for marketing purposes. We do not use your bookmarks to build advertising profiles or track you across other websites.

Data Storage and Security

Storage

Your data is stored securely in Supabase, a cloud database service. All data is encrypted in transit and at rest. We use row-level security policies to ensure that only you can access your own bookmarks and data.

Security Measures

Encryption of data in transit (HTTPS) and at rest
Row-level security policies restricting data access to account owners
Secure authentication using industry-standard protocols
Regular security updates and monitoring

Third-Party Services

We use the following third-party services to operate Shelf:

Supabase: Hosts our database and provides authentication services. Your data is stored in Supabase's infrastructure, which is SOC 2 Type II certified.
OpenAI: We use OpenAI's embedding API to generate vector embeddings for semantic search. Bookmark content (titles, descriptions, notes) is sent to OpenAI to create embeddings, but this data is not used to train OpenAI's models or for any other purpose beyond generating embeddings for your account.

Cookies

We use authentication cookies to maintain your login session. These cookies are essential for the service to function and are not used for tracking or advertising purposes.

Your Rights

You have the following rights regarding your data:

Access: You can view all your bookmarks and account information through the Shelf interface
Deletion: You can delete individual bookmarks or your entire account at any time
Export: You can export your bookmarks through the Shelf interface
Account Deletion: Deleting your account will permanently remove all your bookmarks, embeddings, and account data

Data Retention

We retain your data for as long as your account is active. When you delete a bookmark, it is immediately removed from our database. When you delete your account, all associated data, including bookmarks and embeddings, is permanently deleted.

Children's Privacy

Shelf is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately.

Changes to This 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 page. Your continued use of Shelf after changes become effective constitutes acceptance of the updated policy.
