This Privacy Policy provides comprehensive disclosures regarding user data collection, processing, storage, retention, sharing, security, and deletion procedures for the Fiktu Image Toolbox browser extension (the "Extension").
1.1 Overview & Scope
Fiktu Image Toolbox is designed to assist users in viewing, filtering, organizing, and batch-downloading images and media elements from web pages that users actively visit. We are committed to maintaining the highest level of user privacy and transparency.

Local Processing First: Image detection and filtering occur locally in your browser. Browsing history and text content of visited pages are never collected or sent to our servers.
Optional Account Integration: If you sign in, authentication credentials and account settings are stored in local extension storage (chrome.storage.local) to authenticate requests to our premium feature APIs.
Anonymous Analytics: We collect aggregated, anonymous usage events via Google Analytics 4 (event name, extension version, random client ID, page hostname) to improve software performance. No personally identifiable information or full page URLs are transmitted.
Data Deletion Guarantee: You can delete all local data at any time by clearing extension storage or uninstalling the Extension. Server-side account data will be permanently wiped within 30 days upon email request.
1.3 Data Collection (What Information We Collect)

C. Page Context & Hostname Data
Technical DataActive Tab Page Title and Hostname: Page title and domain name (e.g., www.example.com).
Purpose: To suggest download folder names, apply site-specific image extraction rules, and send domain-level anonymous stats.
Storage & Transmission: Full URLs are never transmitted. Only the hostname is used for anonymous statistics.
D. Feature-Specific Technical Data (Optional user actions)
AI Rule Generation Data: DOM element structure and image URL patterns on the current page, sent only when you actively click the "AI Rule Generator" feature. Processed in real time via HTTPS at https://www.fatkun.net/api/ext/generate-rule and discarded immediately after returning the rule.
