Privacy Policy
Summary
Guisebox changes what chosen websites are told about your browser (the User-Agent header and the matching values page scripts read), only for the sites and tabs you pick. It does not collect, send, sell or share any data. There is no account, no analytics, no advertising and no remote code.
What the extension stores
Guisebox stores only its own data in your browser (storage.local): the rules you create (site address, chosen guise, timer, on or off), the guises you make yourself and your settings (language and theme). This information never leaves your browser. You can export it to a file you keep, delete rules and guises at any time, or remove everything by uninstalling the extension.
What is sent to Zydeno or anyone else
Nothing. Guisebox makes no network requests of its own. The fonts and images it uses are bundled inside the extension. Zydeno receives no information about you, your browsing or your use of the extension.
What changes for the websites you choose
For a site or tab you dress, your browser sends the chosen User-Agent string instead of its own, and page scripts read the matching values (for example navigator.userAgent and navigator.platform). Guisebox also adds a small record to that page as it arrives in your browser, so page scripts and the header stay in step. Guisebox never sends this record anywhere; it holds only the same guise values the header already carries, and scripts on that page can read it like any other page timing record. All other sites see your real browser.
Data the extension reads to do its job
When you open the popup, Guisebox reads the address of the current tab to show which site you are on. When you open "What the site sees", it reads the browser values in that tab (User-Agent and related navigator values) and shows them to you. This happens on your computer; nothing is stored or sent.
Permissions
- storage — keeps your rules, own guises and settings in your browser.
- declarativeNetRequestWithHostAccess — changes the User-Agent header (and, in Opera, the Client Hints headers) only on the sites you dress, and only where you allowed access.
- scripting — makes page scripts on the sites you dress read the same values as the header, and reads those values for "What the site sees".
- activeTab — reads the address of the current tab when you open the popup or use the right-click menu.
- contextMenus — the right-click item "Open this site as…".
- alarms — ends timed rules (15 minutes, 1 hour) on time.
- Optional site access (http and https) — requested from you per site at the moment you dress it, or for all sites only if you choose Everywhere. You can withdraw it in your browser's extension settings at any time.
Children
Guisebox is a general-purpose developer tool and does not collect any information from anyone, including children.
Changes to this policy
If this policy changes, the new version will be published at this address with a new date. Guisebox will never start sending your data anywhere without a new version of the extension and a new policy.
