Privacy Policy — Pinboard Bookmark Enhanced

Last updated: 2026-06-22

Summary

Pinboard Bookmark Enhanced is local-first and bring-your-own-key. It has no developer servers, no analytics, no tracking, and no telemetry — the developer never receives your data. The extension talks only to services you configure (your Pinboard account and the AI / archiving services you choose), and only when you trigger an action.

Data Storage

By default, all data is stored locally on your device (chrome.storage.local) and never leaves it. You can optionally enable settings sync (off by default); when enabled, only your settings — not your saved bookmarks or page content — are synced across your devices through Chrome’s built-in account sync.

Data	Default storage	Synced via Google Account
Settings & preferences	`chrome.storage.local`	Only if you enable settings sync
API keys & tokens (obfuscated)	`chrome.storage.local`	Only if you enable settings sync
Custom CSS & themes	`chrome.storage.local` (chunked)	Only if you enable settings sync
AI result cache	`chrome.storage.local`	No
Tag cache & tag-cleanup state	`chrome.storage.local`	No
Bookmark-status cache	`chrome.storage.local`	No
Offline save queue	`chrome.storage.local`	No
Markdown preview data	`chrome.storage.local`	No
Wayback archive log	`chrome.storage.local`	No

Settings sync is implemented with Chrome’s chrome.storage.sync. The extension itself has no server and uploads nothing on its own. Stored credentials are obfuscated at rest (not cryptographically encrypted) and are sent over HTTPS only to their respective services to authenticate your own requests.

Network Requests

The extension only makes network requests to services you explicitly configure, and — except for the bookmark-status check noted below — only when you trigger an action:

Pinboard API (api.pinboard.in) — to save, retrieve, and manage your bookmarks, authenticated with your Pinboard API token. The tag-cleanup tool, when you run it, downloads your full bookmark/tag list (posts/all, tags/get) and re-saves affected bookmarks to rename or merge tags — all to and from your own Pinboard account. The extension also checks whether the current page is already bookmarked as you navigate, sending the active tab’s URL to the Pinboard API to set the toolbar icon state.
Pinboard website (pinboard.in) — (a) a content script applies your chosen theme CSS and tag-sort tweaks on pinboard.in pages; no data is extracted or transmitted. (b) Save Tab Set POSTs the open tabs’ titles and URLs to pinboard.in/tabs/save/ using your existing pinboard.in login session cookie (not the API token), then opens pinboard.in/tabs/show/ for you to confirm.
AI provider APIs (only when you trigger AI tags, AI summary, Markdown preview, Translate, Ask-the-page, Explain-selection, or batch-save with AI enabled) — the page title, URL, and extracted article text are sent to the provider you chose to generate the requested result. Tag/summary requests send roughly the first 8 KB of extracted text; Markdown preview, Translate, and Ask-the-page send more of the extracted content (sampled to a token budget). Supported providers: OpenAI, Anthropic, Google Gemini, DeepSeek, Qwen, MiniMax, OpenRouter, Groq, Mistral, Cohere, SiliconFlow, Zhipu, Moonshot, a local Ollama instance, or a Custom OpenAI-compatible endpoint (any base URL you enter). No data is sent to any AI provider unless you explicitly trigger it.
Jina Reader (r.jina.ai, optional) — when you choose the Jina content source, the page URL is sent to Jina to fetch a cleaner reader-mode rendering for AI processing or Markdown export. Disabled by default.
Wayback Machine (web.archive.org, optional, opt-in) — when you enable Wayback archiving, the URL of a page you save is sent to the Internet Archive to create a public snapshot. Requires a one-time permission grant; off by default.
Obsidian (local app, optional) — the Send to Obsidian action hands the converted Markdown of the current page to your local Obsidian desktop app via the obsidian:// protocol or the system clipboard. This stays on your device; nothing is sent over the network.

All page content and URLs are transmitted only to the destination you selected for that action, and never to the developer.

Permissions

Permission	Purpose
`activeTab`	Read the current page’s title, URL, and selected text for bookmarking and content extraction
`storage`	Store settings, obfuscated keys, and caches locally (synced only if you enable it)
`scripting`	Inject the Defuddle extractor (and optional per-site rules) into the active tab to pull clean article text — only on explicit action: AI tags/summary, Markdown preview / Translate / Ask / Explain, or batch-save with AI
`tabs`	Read tab URLs/titles for bookmark-status detection, batch save, and Save Tab Set
`notifications`	Show save confirmations and a 30-second Undo button
`alarms`	Keep the service worker warm, refresh caches, and (optionally) prewarm the Pinboard tag list
`host_permissions`	API calls to Pinboard and the 14 user-selectable AI/extraction endpoints (13 cloud providers + Jina)
`optional_host_permissions: :///*`	Requested at runtime to extract page text from non-active tabs during batch save, and to reach a Custom AI endpoint or non-loopback Ollama URL you configure
`optional_host_permissions: localhost / 127.0.0.1`	Reach a local Ollama instance you run on your own machine
`web.archive.org` (requested on demand)	Submit saved URLs to the Wayback Machine when you enable archiving

Third-Party Services

The extension communicates with third-party services only at your direction:

Pinboard — your bookmark service, using your API token (and your login cookie for Save Tab Set)
AI providers — only the provider you select and configure with your own API key (or a local Ollama / custom endpoint)
Jina Reader — only if you select it as a content source
Wayback Machine — only if you enable archiving
Obsidian — your local desktop app, only via Send to Obsidian

No data is shared with any other third party, and none is sent to the developer.

Changes

If this privacy policy changes, the update will be included in the extension release notes and the Last updated date above will be revised.
