Introduction
Lenz (“we”, “us”, or “our”) is a verification service that uses AI, available at lenz.io. This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data.
Information We Collect
Account information
When you create an account (directly or via Google sign-in) we store your email address and display name. If you sign in with Google, we receive your basic profile information (name, email, and profile picture URL) as authorized by you through Google’s OAuth consent screen.
Claim data
When you submit a claim for verification, we store the text you provide and the analysis results generated by our analysis pipeline. By default, new claims are shared with the community (“Public”). You can change the visibility of each individual claim report, or set your preferred default for new reports in your profile settings. Options are “Private Only” (visible only to you), “Shareable” (accessible to anyone with the URL), or “Public”. Public claims may be reviewed and published by our editorial team.
Usage data
We collect basic usage information such as page views, votes, and interaction patterns to improve the service. We use cookies to maintain your session and remember your authentication state.
Payment information
Payments are processed by Stripe. We do not store your credit card details. Stripe may collect information necessary to process your transaction in accordance with their own privacy policy.
Contact form
If you contact us through our contact form, we store your email address, subject, and message to respond to your inquiry.
How We Use Your Information
- To provide and operate the verification service
- To authenticate your account and manage your session
- To process payments and manage subscriptions
- To respond to your inquiries and support requests
- To improve and optimize the service
- To detect and prevent abuse or misuse
Data Sharing
We do not sell your personal information. We share data only with:
- AI model providers (e.g., Google Gemini) — the claim text you submit is sent to third-party AI models for analysis. These providers may have their own data retention policies.
- Stripe — for payment processing.
- Sentry — for error monitoring and service reliability.
- Google Analytics — for usage analytics (page views, interactions). If you are signed in, we send a pseudonymous, hashed identifier derived from your account to enable cross-device analytics. This identifier cannot be used to recover your email or personal details. Google may process this data in accordance with their privacy policy.
- Microsoft Clarity — for anonymous behavioral analytics (click heatmaps, scroll depth, session recordings) to help us understand and improve the user experience. Clarity collects only anonymous usage data and does not track personal information. Clarity may process this data in accordance with Microsoft’s privacy statement.
- Meta (Facebook) Pixel — for advertising measurement and audience building. We send pseudonymous, hashed identifiers (derived from your email address and account) to Meta to help us understand which ads lead to sign-ups and subscriptions. This data cannot be used to recover your personal details. Meta may process this data in accordance with their data policy.
- Google Cloud — our infrastructure provider.
Claims in the Library & Published Claims
Only claims you explicitly mark as “Public” are visible to our editorial team for review. If an editor publishes your claim, the claim text, analysis, score, and conclusion become publicly visible. By default, published claims are completely anonymous — no personal information such as your name, email address, or account details is shared with other users or displayed alongside the claim.
When you create an account, we assign a random anonymous display name (e.g. “Curious Falcon 7a3f”) that does not reveal your identity. By default, this name is shown on your published claims, annotations, challenges, and community leaderboards. You can change your display name or disable visibility entirely by toggling “Show my name on claims” in your profile settings. When disabled, your name will no longer appear on any public pages.
Data Retention & Deletion
You can permanently delete individual claims at any time. Deletion is irreversible — the claim text, analysis, and all associated data are removed from our systems. You can also delete all claims at once from your history page. If you wish to delete your account and all associated data, please contact us at our contact page.
Cookies
We use essential cookies to maintain your authenticated session
and CSRF protection. We also use Google Analytics, which sets
first-party cookies (e.g. _ga) to
collect anonymous usage statistics, and Microsoft Clarity, which
sets cookies (e.g. _clck, _clsk) to
help us understand and improve the user experience through
behavioral analytics such as heatmaps and session recordings.
We also use the Meta (Facebook) Pixel, which sets advertising
cookies (e.g. _fbp, _fbc) to measure
ad performance and build advertising audiences.
Children’s Privacy
Lenz is not intended for use by children under 13. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify users of significant changes by posting a notice on the site. Continued use of the service after changes constitutes acceptance of the updated policy.
