Vivies Stalker for Instagram Privacy Policy

Data Collection

This extension does not collect, store, transmit, or share your personal data or browsing information with any external server operated by the developer. All analysis data (followers, following, posts, stories) and user preferences (theme, language, module settings) are stored locally in your browser using Chrome's built-in storage APIs and never leave your device, except for direct requests sent to Instagram to provide requested features.

How It Works

This extension analyzes Instagram data directly from your account session in your browser. It fetches content from Instagram endpoints using your existing logged-in session and processes results locally inside the extension. The extension does not run a backend server and does not forward your data to third-party servers.

Network Requests

The extension communicates only with official Instagram/Meta domains needed for functionality:

• instagram.com: fetch user profiles, stories, highlights, search results, and detect active Instagram context.

• i.instagram.com: access Instagram API endpoints for followers, following, posts, post likers, and story-related data.

• cdninstagram.com: load profile pictures, media thumbnails, and media files served by Instagram CDN.

• fbcdn.net: load media files from Meta/Facebook CDN subdomains (for example scontent-*.fbcdn.net, video-*.fbcdn.net).

No request data is sent to any developer-owned external server.

Third-Party Services

This extension does not use third-party analytics, advertising, tracking, or telemetry services.

Permissions

The extension uses the following permissions only for the purposes listed below:

• storage: save module states, cached analysis data, theme/language settings, favorites, alarms, and related local preferences.

• downloads: save selected Instagram media to your device when you trigger download actions.

• alarms: run periodic local checks for story alarm features.

• cookies: read Instagram csrftoken cookie to make authenticated requests to Instagram APIs from the extension.

• declarativeNetRequest: block Instagram "seen/receipt" story-view tracking requests when story-viewer protections are enabled.
