Privacy Policy — Screenshot Annotation

This Privacy Policy describes how the Screenshot Annotation browser extension ("the extension") handles information when you use it. By installing the extension, you agree to the practices described below.

What the extension does

When you trigger a screenshot, the extension:

Captures the visible area of your current browser tab using Chrome's chrome.tabs.captureVisibleTab API.
Records the position and dimensions of elements on the page (via getBoundingClientRect) so annotations can snap to them.
Reads visible text on the page (via the DOM) only when you click the "Extract text" button.
Opens an in-page editor where you can draw arrows, boxes, text, and other annotations on top of the screenshot.
Lets you download the result as PNG / JPG / PDF, or copies it to your clipboard.

Permissions and why each is required

activeTab Access the current tab to capture a screenshot when you click the toolbar icon, press the keyboard shortcut, or right-click the page.

scripting Inject a content script that records element positions, enabling the DOM-snapping annotation feature.

storage Remember your preferences (color, line thickness, font, language) between sessions.

unlimitedStorage Temporarily hold the captured screenshot in local storage while you annotate. High-DPI screenshots can exceed Chrome's default 5 MB quota.

contextMenus Add "Free region capture" to the page's right-click menu.

Host permission justification

The extension operates on <all_urls> because users may want to capture screenshots on any site they visit — a GitHub repo, an internal dashboard, a news article, or a web app. Restricting to specific hosts would make the tool unusable for the majority of use cases.

The extension accesses page content ONLY at the moment the user explicitly triggers a capture (toolbar click, keyboard shortcut, or right-click menu). It does NOT monitor browsing activity, does NOT run in the background, does NOT transmit any page content anywhere, and does NOT store page data after the editing session closes.

What is stored locally

The following data is stored in your browser's local storage (chrome.storage.local) and never transmitted anywhere:

Your annotation preferences (color, size, font, language).
The most recent screenshot, only while you are editing it. This is cleared when you close the editor or capture a new one.
Custom background images that you explicitly upload.

Uninstalling the extension removes all of this data.

What we do NOT do

Not collect, transmit, or sell personal data.
Not use analytics, telemetry, or tracking pixels.
Not connect to any remote server. The extension has no network requests.
Not read, modify, or transmit the content of your screenshots beyond your own browser.
Not use third-party scripts or load remote code.

Screenshots and clipboard

The screenshot you capture stays on your device. When you choose "Copy to clipboard" or "Download", the data goes only to your operating system clipboard or your downloads folder, under your control. The "auto-copy on finish" feature writes the final image to your clipboard locally; it does not send the image anywhere else.

Webpages you capture

The extension only operates on the tab you actively trigger it on. It does not monitor browsing activity, does not run in the background beyond the moment of capture, and does not retain any information about the pages you visit. The DOM data (element positions, visible text) is held in memory only for the duration of your editing session and is discarded when you close the editor.

Children's privacy

The extension is not directed at children under 13 (or the equivalent age in your jurisdiction) and does not knowingly collect any data from anyone, including children.

Permissions changes

If a future version of the extension requests new permissions, this policy will be updated and the new permissions will only take effect after you accept them through Chrome's standard update flow.

Changes to this policy

If this policy changes, the updated version will be posted at this same URL with a new "Last updated" date.

Your screenshots never leave your browser.
