Privacy
Policy
This policy explains, in simple terms, how Viewer Lens handles the information needed to provide our comment analysis service.
Last Updated: May 2026
1. Information We Collect
Account Information
We may collect details such as your name, email address, login details, plan status, and basic account preferences.
Platform Content
When you use Viewer Lens, we process the platform URLs you submit (e.g. YouTube video links) and the publicly available comments or posts fetched from those URLs. This content is used solely to generate the analysis you request.
Usage Information
We may collect basic usage, device, browser, and session information to keep the service reliable, secure, and easier to improve.
2. Platform Data & Third-Party APIs
We only access publicly available content — never private accounts, inboxes, or personal data beyond what the platform makes public.
Access model depends on the platform
YouTube: You can analyse publicly available videos by URL without connecting an account. If you choose to connect your own YouTube channel, we use Google OAuth read-only access to verify the channel, show your uploaded videos, and generate channel-level analytics for that connected channel.
Reddit: No account connection required. You can analyse publicly available threads — no ownership verification is performed.
Instagram & Facebook: Account connection required via OAuth. You can only analyse your own connected pages and posts — not arbitrary public profiles. This is enforced by the Meta API, not just by our policy.
In all cases you are responsible for ensuring your use of analysis results complies with applicable law and platform rules.
YouTube
We use the YouTube Data API v3 to fetch public video metadata and comments for video analysis. If you connect your YouTube channel, we also use read-only OAuth access to verify the channel identity, retrieve basic channel metadata, list your uploaded videos, and generate private channel analytics such as audience memory, growth opportunities, content ideas, and relation maps. Data is used solely for your requested analysis and is not shared with advertisers. By using this feature you also agree to the YouTube Terms of Service. Google's collection and use of data is governed by the Google Privacy Policy.
Data fetched: comment text, author display name, like count, timestamp, video title, channel name, published date, comment count, channel ID, channel title, handle, thumbnail, subscriber/view/video statistics, and upload list for connected channels. Author display names are stored internally but masked in the app — only the first character is shown (e.g. @J***) to protect commenter privacy.
Viewer Lens requests read-only YouTube access only. We do not upload, edit, delete, publish, comment, modify playlists, or change YouTube channel settings. The YouTube channel connection and Channel Analytics flow is currently under verification with the Google team.
Instagram & Facebook
When you connect your Meta account, we receive an OAuth access token scoped to the permissions you approve. This token is stored securely and used only to fetch your content for analysis. You can revoke access at any time from Account Settings or directly via Facebook App Settings. Data processing is governed by the Meta Privacy Policy.
Data fetched: comment text, commenter display name, like count, timestamp, and post metadata for your connected pages/profiles only.
Data fetched is limited to public post and comment content. No Reddit account data, private messages, or subreddit membership information is accessed. Use is governed by the Reddit Privacy Policy.
Data fetched: comment text, author username, upvote count, timestamp, and post/thread metadata for public content only.
3. AI Processing
Comment text is sent to a third-party AI provider to generate analysis. No personal account data is included.
Google Gemini
We use Google Gemini to analyse comment text and generate themes, sentiment scores, summaries, and content ideas. To do this, fetched comment text is sent to Google's Gemini API as part of the analysis request.
Comment text and video/post metadata only — no account details, email, or payment data

6. Security
How We Protect Data
