EvidenceLens — Check what's true before you believe it

Last updated: June 15, 2026

1. Information We Collect

Account Data: When you sign in with Google, we receive your name, email address, and profile picture. We do not access any other data from your social account.

Usage Data: We track which product features you use (verifications, summaries, chats, and similar analysis actions) and the YouTube video IDs you analyze. This data is used to enforce plan limits, improve the service, and display your activity dashboard.

Processing Data: To generate analyses, summaries, and source-based answers, we process the YouTube transcript, web page content, or PDF text you submit, along with any related questions you ask inside the product.

Device and Security Data: When you sign in or link a device, we may store device type, browser or app metadata, and IP address to help manage active devices, improve account security, and enforce device limits.

API Tokens: Each installation generates a unique API token stored locally on your device and as a hash on our servers.

Diagnostic Data: If the mobile app or browser extension encounters an unexpected failure, we may send technical diagnostics such as error messages, stack traces, app or browser version, and device metadata to our monitoring provider so we can investigate and fix stability issues. We do not intentionally include transcript content, chat prompts, or authentication secrets in these reports.
