+# Privacy Policy for Vision Start
+
+This Privacy Policy describes how the Vision Start Chrome extension handles user information.
+
+## Information Stored by the Extension
+
+Vision Start stores extension settings and user-provided configuration locally in the browser using Chrome's local extension storage.
+
+This information may include:
+* Start-page preferences and appearance settings;
+* Bookmarks, shortcuts, or server and services addresses added by the user;
+* Configuration for features enabled by the user.
+
+This information is used only to provide the extension's functionality. It is not transmitted to, collected by, or stored on servers operated by the developer.
+
+The developer does not have access to information stored locally by the extension.
+
+## Server Status Requests
+
+Vision Start can send network requests to server addresses configured by the user in order to check whether those servers are available.
+
+These requests are sent directly from the user's browser to the configured server. The developer does not receive, proxy, log, or store these requests.
+
+The destination server may receive standard network information associated with the request, such as the user's IP address, browser request headers, and the requested server address. The handling of that information is controlled by the operator of the destination server.
+
+## External Favicon Service
+
+Vision Start uses the Google Favicon Service (https://www.google.com/s2/favicons) to retrieve icons for websites configured by the user.
+
+When an icon is requested, the relevant website domain is sent directly from the user's browser to Google. Google may also receive standard information associated with the network request, such as the user's IP address, browser request headers, and the requested domain.
+
+The developer does not receive, proxy, log, or store these requests. Google's handling of information is governed by the Google Privacy Policy.
+
+## Data Sharing and Sale
+
+The developer does not sell, rent, trade, or use user information for advertising, analytics, profiling, or marketing.
+
+No locally stored extension data is shared with the developer or with third parties, except for the direct network requests described above that are necessary to provide user-requested features.
+
+## Data Retention and Deletion
+
+Information stored by Vision Start remains in the browser until the user:
+
+* Deletes the relevant information through the extension;
+* Clears the extension's browser storage; or
+* Uninstalls the extension.
+
+## Security
+
+Vision Start is designed to keep user configuration on the user's device. Users should use HTTPS addresses whenever possible when configuring remote servers or external resources.
+
+## Changes to This Policy
+
+This Privacy Policy may be updated if the extension's functionality or data-handling practices change.
+
+Any updated version will be published at this location with a revised effective date. Material changes to how user information is handled will also be disclosed through the extension or its Chrome Web Store listing where appropriate.
+
+## Contact
+
+Questions about this Privacy Policy may be submitted through the developer's GitHub profile: https://github.com/ivanch

 - **Server Status Widget** — Bottom-center glass pill that periodically "pings" configured server addresses and shows online/offline indicators. Ping uses an image-load trick (`components/utils/jsping.js`) with a 5s timeout, at a configurable frequency.
 - **Wallpaper background** — Fullscreen background image with adjustable blur, brightness, and opacity, rendered behind a soft readability layer for the liquid-glass UI. Supports rotating through multiple wallpapers at an hourly cadence selected by slider (`1h`–`48h`).
   - Built-in wallpapers: Abstract, Abstract Red, Beach, Dark, Mountain, Waves (`components/utils/baseWallpapers.ts`).
-  - User wallpapers: upload from a file (≤4MB, ≤4.5MB base64) or add by URL; stored in `chrome.storage.local` when available, falling back to storing the URL directly on CORS failure.
-- **Icon library & auto-fetch** — Website icons can be picked from the [Dashboard Icons](https://dashboardicons.com/) library (metadata pre-downloaded to `public/icon-metadata.json`) or auto-fetched from the target site's `apple-touch-icon`/`icon` link tags, with a fallback to Google's S2 favicon service.
+  - User wallpapers: upload from a file (≤4MB, ≤4.5MB base64) or add by URL. Remote URLs remain lightweight entries in the `userWallpapers` index; uploaded image data is stored in `chrome.storage.local` when available.
+- **Icon library, auto-fetch & cache** — Website icons can be picked from the [Dashboard Icons](https://dashboardicons.com/) library (metadata pre-downloaded to `public/icon-metadata.json`) or auto-fetched from the target site's `apple-touch-icon`/`icon` link tags, with a fallback to Google's S2 favicon service. Tiles opportunistically cache CORS-readable icon responses as data URLs in `chrome.storage.local` and retain the original URL when caching is unavailable.
 - **Configuration panel** — Slide-in right-side modal with four tabs: General, Theme, Clock, Server Widget. Includes **Export** (downloads a JSON bundle of selected `localStorage` keys) and **Import** (restores from JSON and reloads the page).
 - **Edit mode** — Toggle via the top-left pencil button; reveals per-tile glass action toolbars, per-category edit buttons, and ghost glass "add" tiles.
 - **Liquid glass design language** — Soft translucent surfaces, restrained edge highlights, moderate backdrop blur, soft shadows, cyan focus states, and iOS-like easing tokens (`ease-ios`, `ease-spring`, `ease-liquid`) defined in `index.css`.
 
 Performance notes:
+- Website tile icons check a deterministic `vision-start:icon:<encoded-source-url>` entry in `chrome.storage.local` before loading the external URL. Cache population uses ordinary CORS-enabled `fetch`, deduplicates in-flight requests, stores only `image/*` responses up to 256KiB, and never intercepts or proxies outside requests.
 - Modals (`ConfigurationModal`, `WebsiteEditModal`, `CategoryEditModal`) are code-split via `React.lazy` + `Suspense` and only loaded when opened. `ConfigurationModal` is the heaviest chunk (it pulls in `@hello-pangea/dnd` via `ServerWidgetTab`); the rest of `@hello-pangea/dnd` is isolated from the initial load.
 - `WebsiteTile` and `CategoryGroup` are wrapped in `React.memo`; `App.tsx` handlers are `useCallback`-stabilized and pure alignment helpers are hoisted to module scope, so opening a modal / toggling edit no longer re-renders every tile.
 - `Clock` updates on the minute boundary (one `setTimeout` → `setInterval(60_000)`) instead of every second.

 `Dockerfile` builds in Node 22 Alpine (`npm ci` → runs `scripts/prepare_release.sh` → `npm run build`) and serves `/app/dist` + `manifest.json` via nginx:alpine on port 80.
 
 ### CI/CD (Gitea Actions)
+- `release.yaml` validates each `vX.Y.Z` tag and stamps the version into `manifest.json` (`"version": "0.0.0"` → the tag) in each build checkout before producing the extension archive and production image.
+- **`pull-request.yaml`** — Triggers on pull request open, reopen, and synchronization. It builds and uploads a PR extension archive containing `dist/`, unpacks that archive in a separate Playwright job to generate the three demo screenshots, and uploads both artifacts (screenshots are retained for 30 days). For same-repository PRs, it maintains one Gitea PR comment with inline image attachments; fork PRs retain artifacts but skip the comment because their workflow token is read-only.
+- After `deploy_vision_start` succeeds, `release.yaml` uses Playwright Chromium against the deployed production page and seeds each browser context from `scripts/demoData.json`. It regenerates `home.png`, `editing.png`, and `configuration.png` at exactly 1280×800, uploads them as artifacts (retained for 30 days), and attaches them as individual Gitea release assets.
 - **`main.yaml`** — Triggers on push to `main` (and `workflow_dispatch`). Builds, pushes a `staging` multi-arch (amd64/arm64) image to `git.ivanch.me/ivanch/vision-start:staging`, then SSH-deploys on the staging host via `docker compose up -d --force-recreate`.
 - **`release.yaml`** — Triggers on `v*` tags. Builds, zips `dist/` + `manifest.json` as `vision-start-<tag>.zip`, runs `scripts/check_virustotal.sh` against it (publishes analysis URL + detection ratio on the release body), creates a Gitea release, pushes a `latest` multi-arch image, and SSH-deploys to production.
 
@@ -222,9 +234,10 @@ External assets fetched at build time by `scripts/prepare_release.sh`:
 
 - **`EditModal.tsx` has been removed.** It was a legacy drag-and-drop editor that imported non-existent `lucide-react` and `./IconPicker`; it was never wired into `App.tsx`. Use `WebsiteEditModal.tsx` / `CategoryEditModal.tsx` instead.
 - **`@hello-pangea/dnd`** is used only in `ServerWidgetTab.tsx` (server reorder), which itself is imported by the lazy-loaded `ConfigurationModal`, so it lives in a separate chunk and is absent from the initial page load. `WebsiteTile` moves tiles within their own category via simple left/right buttons (no cross-category movement), not drag-and-drop.
-- **Chrome storage is optional.** `StorageLocalManager` checks availability once (`checkChromeStorageLocalAvailable`) and caches it. When unavailable (e.g., running as a plain web page), wallpaper upload/delete flows are gated off and `addWallpaperToChromeStorageLocal` throws.
+- **Chrome storage is optional.** `StorageLocalManager` checks availability once (`checkChromeStorageLocalAvailable`) and caches it. Remote wallpaper URLs work without it because their URLs live in `userWallpapers`; file upload is gated off when unavailable, and `addWallpaperToChromeStorageLocal` throws if called without it.
 - **Wallpaper rotation** is time-based, evaluated on render/mount rather than via a timer. It reads `wallpaperState` from `localStorage`, advances the index if the frequency window has elapsed, and writes it back; the frequency is clamped to 1–48 hours, while older saved values like `1d`/`2d` still resolve to their hour equivalents. The renderer clamps `currentIndex` to the valid range of the current selection and walks the list forward to find a wallpaper whose data actually resolves (so deleting the currently-displayed wallpaper, or shrinking the selection, never leaves the background blank); if no wallpaper resolves, the background layer is hidden. When the selection becomes empty, `wallpaperState` is reset and the background is hidden. A manual "Next Wallpaper" button in the Theme tab advances `currentIndex` (with wraparound) and bumps a `wallpaperVersion` nonce in `App.tsx` that retriggers the renderer.
 - **Icon picker** in `WebsiteEditModal` loads `/icon-metadata.json` at runtime and expands each icon's `colors` into duplicate-name entries so color variants are searchable.
+- **Website icon cache** is persistent only in `chrome.storage.local`; it is rebuilt from website icon URLs after configuration import. Only CORS-readable `http`/`https` image responses no larger than 256KiB are cached.
 - **`tsconfig.json` does not emit JS** (`noEmit: true`, bundler resolution); Vite handles all transpilation.
 - **`tailwind.config.js` safelists** a set of `w-[Npx]/h-[Npx]` classes because `WebsiteTile` generates tailwind classes dynamically from `tileSize` (`w-[42px]`, etc.).
 - **Project guidance note** in `PROJECT.md`: do not use `npm run dev` for real verification — use `npm run build`.
