itch.io Tag Hider — Privacy Policy

This extension does not collect, transmit, or store any personal data on remote servers.

Data storage:
- Tag list and auto-mode preference are stored in browser.storage.sync, which Firefox syncs across your signed-in devices via Mozilla's standard sync mechanism. This data never leaves Mozilla's infrastructure.
- The game_id blacklist cache is stored in browser.storage.local, which is per-device and never leaves your device.

Network requests:
- The extension makes HTTP requests only to itch.io and its subdomains (*.itch.io). These requests load game detail pages so the extension can read each game's tags. No data is sent to any other server.
- No analytics. No tracking. No telemetry.

Permissions:
- storage: to save your tag list and the local game_id cache
- activeTab: to read the currently visible itch.io page when you click "Manual collection"
- webRequest, webRequestBlocking: to remove X-Frame-Options headers from itch.io subdomain responses, which is required to load detail pages in hidden iframes for tag detection
- Host permissions for ://itch.io/ and ://.itch.io/*: to operate on itch.io pages

The extension never sends or receives data outside itch.io. All filtering is performed client-side via CSS hiding.
