Privacy Policy

AZLens is a tool for YouTube creators. This policy explains what data we handle when you use it.

Account data — when you sign in with Google, we receive your name, email, and profile picture through Firebase Authentication.

YouTube data you authorize — with your consent through Google, we access your channel and video statistics and analytics (for example views, subscribers, watch time, and video metadata) to power your dashboard and reports.

Content you enter — keywords, topics, tracked channels, and messages you send to AI features.

Usage data — your subscription tier and credit balance, so we can meter AI features.

We use your data only to provide and improve the Service: to show your analytics, run keyword and competitor research, generate AI ideas and insights, and meter usage.

We do not sell your data, share it with data brokers or advertisers, use it for targeted advertising or lending, or use it to train general-purpose AI/ML models. Google user data is used solely to provide the user-facing features described in this policy.

AZLens's use and transfer of information received from Google APIs to any other app adheres to the Google API Services User Data Policy, including the Limited Use requirements.

When you use an AI feature, the relevant data on the page (such as your channel stats, your watchlist, or the text you enter) is sent to our AI provider, Anthropic, to generate the response. AI features are designed to reason over your real figures and are instructed never to fabricate analytics numbers. Anthropic processes this data only to return the response and does not use it to train its models.

Account data, tracked channels, and AI chat history are stored in Google Firebase (Cloud Firestore). Some preferences and your most recent keyword/niche activity are cached locally in your browser to improve the experience.

We keep your account data, tracked channels, and AI chat history for as long as your account is active. Cached YouTube figures used to power the dashboard are short-lived and refreshed automatically; your YouTube access token is not stored between sessions.

You can delete your data at any time: remove tracked channels and clear your AI chat history from within the app, and revoke AZLens's access to your Google account from your Google account permissions. To delete your account and all data associated with it, contact us via the Contact page and we will remove it, normally within 30 days.

We rely on Google (Firebase Authentication and Firestore; YouTube Data and Analytics APIs) and Anthropic (AI processing). We do not transfer or sell Google user data to any other third parties. Your use of YouTube data through AZLens is also covered by the Google Privacy Policy.

You can remove tracked channels and clear your AI chat history in the app at any time. You can revoke AZLens's access to your Google account from your Google account permissions. To request deletion of your account data, contact us.

We use Google's infrastructure and per-user security rules so that your data is only accessible to you. No system is perfectly secure, but we take reasonable measures to protect it.

AZLens isn't directed to children and is intended for users old enough to hold a Google/YouTube account and manage a channel.

We may update this policy; material changes will be posted here with a new "last updated" date.
