Privacy Policy
Effective date: March 11, 2026

Markbase is operated by Ali Reza Erfan, an individual developer
based in Calgary, Canada.

INFORMATION WE HANDLE

When you use Markbase or the Markbase browser extension, we handle:
- Account information: name, email address, and authentication credentials
- Bookmark data: URLs, page titles, notes, tags, status values, excerpts, and selected text you explicitly save
- Product settings: preferences needed to keep the service working
- Extension local state: cached bookmark data and saved-status awareness stored in browser extension storage

We do not collect your browsing history. The extension does not automatically record pages you visit. Information is only handled when you explicitly use the product to save, update, remove, retrieve, or search bookmarks.

HOW WE USE THIS INFORMATION

We use this information to authenticate your account, save and retrieve bookmarks, power product features, and respond to support requests.

Some features use third-party AI APIs to process bookmark content for tagging and summarization. This content is not used to train models and is not stored by AI providers beyond the scope of the API request.

BROWSER EXTENSION PERMISSIONS

storage: stores auth token, local bookmark cache, and preferences
activeTab: reads current page URL and title only when you save a page
tabs: detects open Markbase tabs for auth handshake and saved-status
contextMenus: adds Save to Markbase option on right-click
alarms: schedules periodic background cache refresh
notifications: shows toast when serendipity engine finds a relevant saved bookmark

INFORMATION SHARING

Markbase uses the following providers:
- Supabase: database hosting and authentication
- Vercel: application hosting
- Resend: transactional email delivery
- Anthropic and OpenRouter: AI language model APIs for tagging and summarization

We do not sell personal information to any third party.

DATA DELETION

To delete your account and all data, go to Markbase Settings → Account → Delete Account. This permanently removes all saved bookmarks, notes, tags, and account information. You can also email hello@markbase.app to request manual deletion.

SECURITY AND RETENTION

We use HTTPS for all data in transit. We retain your data for as long as your account is active. Extension data is stored locally until you disconnect the extension or clear it manually.

YOUR RIGHTS AND CHOICES

You can access, export, update, or delete your data at any time from within the product. You can disconnect the extension from your browser's extension manager at any time. You can opt out of the weekly digest email from Settings or via the unsubscribe link in any email.

If you are located in Canada, your information is handled in accordance with PIPEDA and the Alberta Personal Information Protection Act (PIPA).

CHILDREN'S PRIVACY

Markbase is not intended for children under 13. We do not knowingly collect personal information from children.

POLICY CHANGES

We may update this policy from time to time. When we do, we will update the effective date at the top of this page.
