What the extension installs and what it leaves alone
The extension contains the theme renderer, site adapters, validation rules, and reviewed focus modules. It stores installed manifests and current preferences in browser extension storage. The original websites continue to handle accounts, content, media, conversations, and navigation. SiteSkin does not create a replacement account, move user data, or publish the customized appearance for other visitors.
Access is requested for supported websites rather than silently assumed for every page. Someone who wants only a YouTube theme can leave Reddit and ChatGPT disabled. The public website may send an installation identifier or short preview request to the extension, but the extension validates the sender and obtains the authoritative manifest before applying it. This keeps the website interface convenient without turning a web page into a privileged extension controller.
Using the current developer build responsibly
The current download is an unpacked developer build, so Chrome requires the extension management page and Developer mode. Unzip the package, load the extension folder, copy its generated extension identifier, and save that identifier in the SiteSkin editor. This connection allows the official website to send a selected skin identifier or preview revision to the locally installed runtime.
A developer build is useful for product validation, but it is not the final distribution experience. Users should download it only from the official SiteSkin domain, inspect the requested permissions, and remove earlier folders before loading a new version. A store release can later replace the manual steps with a verified listing and a stable extension identifier. The same structured manifest and adapter design can remain unchanged underneath that simpler installation flow.
Frequently asked questions
Why does the website theme extension need site access?+
It needs permission to insert the approved style layer on a selected website. SiteSkin requests supported sites separately so unrelated pages can remain untouched.
Can I uninstall SiteSkin without changing my accounts?+
Yes. Removing the extension removes its local themes and restores original website presentation. It does not delete or modify the underlying website accounts.
