Privacy Policy — CSS Peek

Last updated: September 2026

What the extension does

CSS Peek lets you hover any element on a web page to see its computed CSS (a curated, decluttered view — not every browser-default property) and copy it with one click. Pseudo-element inspection (::before/::after) is a paid feature unlocked with a license key.

Data collection

This extension does not collect, transmit, or sell any personal data, browsing history, or page content. All CSS inspection happens locally in your browser using the standard getComputedStyle() API — nothing is sent to any server by the extension itself.

The only data stored is your license activation status, kept locally via Chrome's chrome.storage.local API (never storage.sync, so it is not synced to any account or server).

License key verification (paid tier) is planned to go through Gumroad's License Verification API, which only receives the license key you enter — no browsing data, no page content.

Permissions

• content_scripts matches (<all_urls>) — needed so you can inspect elements on any site you visit. The script is passive until you explicitly start inspecting (via the popup button or the Alt+Shift+C shortcut); it does not read or transmit page content otherwise. No host_permissions and no webRequest are used.
• storage — used only to remember whether your license is active, locally on your device.
