Ultrafill has no analytics or telemetry and uses no developer-run servers. Preferences and optional framing memory are stored in browser local/session storage. Site memory stores the site origin and framing settings, never full page URLs. Private-window viewing state is not persisted.

Detection and effects process selected video frames locally. Audio pulse reads energy from an explicitly activated media stream tap; it does not record audio, reroute playback or access the microphone. Frames and audio samples are neither saved nor sent to any service. Diagnostics are displayed/copied only on request.

Browser sync is off by default. If enabled, the browser's sync service carries preferences, named profiles, chosen site-rule domains and a random device token used only to resolve preference conflicts. Saved per-site/tab viewing state is excluded. Firefox also requires optional data consent for preferences and chosen domains. Turning sync off stops this extension's sync writes/reads; existing cloud data remains under the browser account's controls. Device preferences can override shared preferences. No synced data is sent to us.

This website

This website uses no analytics, advertising, tracking cookies, embedded third-party media or external font services. The interactive demonstration is a local illustration. Opening a store or repository link takes you to that service, whose privacy policy applies. The static hosting provider may process ordinary connection/access logs needed to serve and secure the website.
