Privacy Policy

Bookmark Atlas is a local-first Chrome extension. It does not sell, analyze, or upload your bookmarks, open tabs, browsing history, or canvas content to a developer server. It does not include ads, trackers, or remote code execution.

Data handled by the extension

• Chrome bookmarks are read and modified locally through the Chrome Bookmarks API for user-requested bookmark features.
• Website icons are read from Chrome's local Favicon API cache.
• Open tabs and browsing history are read locally to produce pre-search results.
• The full Excalidraw canvas and user-added binary attachments are stored in local IndexedDB, with chrome.storage.local as a fallback.
• Lightweight shapes, text, bookmark references, document settings, and library items may be compressed and written to chrome.storage.sync when Chrome Sync is available and quota allows.
• Viewport, zoom, sidebar, and drawing-tool preferences remain local.
• Images and binary attachments are not uploaded to Chrome Sync.

Sync behavior

Chrome Sync is controlled by the user's Chrome account settings. Bookmark Atlas writes eligible lightweight data when local changes occur and listens for Chrome storage change events in other open extension pages. This usually behaves as near-real-time sync, but Chrome does not guarantee an exact delivery latency across devices or browser tabs.

Synced bookmark cards are reconciled by normalized URL, title, and folder path. Chrome bookmark IDs are local to a browser profile and are not treated as cross-device identifiers.

Remote requests

When the user selects Baidu, Bing, or Google as the active built-in search engine, input text is sent to that provider's fixed suggestion endpoint. Chrome Default and custom engines do not call an extra remote suggestion endpoint. Embedded websites load in sandboxed iframes and may receive normal browser requests, cookies, and account state according to browser rules. Bookmark Atlas does not proxy, inspect, or record those requests.

For official YouTube /embed/ player requests created by Bookmark Atlas, a declarative rule sets a fixed client referrer. The rule does not read request content and does not apply to YouTube players created by other websites.

Data deletion

Uninstalling the extension removes local extension storage from the device. Chrome account sync data is managed by Chrome. Uninstalling Bookmark Atlas does not delete the user's Chrome bookmarks.

Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
