DeepScope Privacy
Last updated:
Extension purpose
DeepScope detects technologies used by the active website and shows the evidence behind each supported detection. The extension runs after the user opens or invokes it for the selected HTTP or HTTPS tab.
Data DeepScope handles
Depending on the fact and detector definitions needed for the current page, DeepScope may analyze the page URL and hostname, DOM markers, meta tags, script and resource URLs, selected response or request header data available to the extension, cookie names, storage key names, JavaScript global names, and short bounded evidence snippets.
DeepScope does not intentionally collect passwords, cookie values, localStorage values, sessionStorage values, payment details, health information, precise location, authentication secrets, or personal communications. Page content can contain incidental personal or sensitive text, so persisted evidence values are bounded and redacted before storage.
Local analysis and storage
Page analysis is local-first. Detection results, snapshot records, matcher state, and redacted replay summaries are stored in Chrome extension local storage so reopening the popup can show recent results without immediately repeating all detector work.
Cached detector records remain local to the browser profile. Users can clear stored detector data from the popup or remove the extension to delete extension storage.
Remote services
The first release does not send page analysis, detector evidence, browsing activity, or cached results to a Kaiju server. Detector definitions, matcher workers, popup assets, and registry artifacts are bundled with the extension. DeepScope does not sell user data, use it for advertising, or transfer page analysis to third parties.
Permissions
activeTab
Allows DeepScope to inspect the current tab only after the user opens or invokes the extension. This provides temporary access for the selected page instead of persistent access to every website.
scripting
Injects the packaged observation script into the active tab after user action and supports bounded page-signal collection used by the fact and detection pipeline.
storage
Stores local detection results, redacted replay summaries, revision state, and cache records so the popup can show recent results and follow live updates.
offscreen
Runs local matcher work outside the popup and service worker so heavier analysis does not block the interface and remains reliable under Manifest V3 service-worker lifecycle behavior. It does not display hidden user interface, play media, record audio, or load remote code.
Product website
The DeepScope product website may receive ordinary request information needed for hosting, security, and delivery. Email links open the user’s email application and do not submit a website form. Optional visitor tracking remains disabled by default in the supplied website configuration.
Requests and changes
Contact hello@kaiju.industries with a privacy request. This notice may change when DeepScope adds account login, synchronization, telemetry, diagnostics export, or another remote service. The date above identifies the latest revision.
