Privacy Policy — ScrnCap

Last updated: 2026-06-28

ScrnCap ("the extension") is a screenshot tool that runs entirely inside your web browser. It has no account system and no backend server.

Data we collect

None. ScrnCap does not collect, store on any server, transmit, share, or sell any personal data, browsing history, or screenshot content. There is no sign-in, no analytics, and no telemetry. Every screenshot you take is captured, annotated, and exported locally on your own device. Settings are stored locally in your browser via the standard extension storage and never leave your machine.

Permissions and why they are needed

• activeTab — Grants one-time access to the current tab only when you trigger a capture, so its pixels can be read for the screenshot.
• scripting — Injects the measurement, scrolling, and selection-overlay helpers into the page on demand during a capture. ScrnCap does not run a persistent content script.
• tabs — Reads tab titles/URLs and switches the active tab when you batch-capture several open tabs in sequence.
• storage — Persists your settings and hands the captured image to the local preview/editor page.
• unlimitedStorage — Lets large full-page or batch captures be held locally without hitting the small default storage quota.
• contextMenus — Adds right-click capture entries on the page.
• downloads — Saves the exported image or PDF to your Downloads folder.
• Host access (<all_urls>) — Required so capture (and the capture helpers) can work on whatever page you are on; full-page, region, and fixed-size modes need to read and scroll the current page. Access happens only when you start a capture.

Remote code

ScrnCap does not load or execute any remote code. All JavaScript and WebAssembly are bundled in the extension package.
