In a Next.js app using Sentry for error tracking, implement explicit user consent for error telemetry and scrub any PII from events. Add a beforeSend hook to remove personal data (emails, usernames, user IDs), strip sensitive request headers (e.g., cookies), and enable anonymizeIp. Ensure sendDefaultPii is false and consider reducing data collection by lowering tracesSampleRate. Provide a visible privacy notice or consent toggle for telemetry.

Replace the direct POST to the Sentry ingest endpoint with the official Sentry SDK in your Next.js app. Remove any query parameter containing sentry_key from the URL. Use the DSN-based configuration loaded from environment variables (e.g., SENTRY_DSN) and initialize Sentry with Sentry.init({ dsn: process.env.SENTRY_DSN, tracesSampleRate: 1.0 });. Do not construct ingestion URLs manually or expose keys in query strings. Ensure logs and error reports are sent through the SDK over HTTPS only and that no credentials appear in browser history, logs, or referer headers. Validate that no other credentials are sent in URLs.

In the signup/landing page, locate any code that initializes or calls AI/LLM endpoints on initial render. Move such calls to be triggered by user action (e.g., click to open AI widget). Implement lazy-loading, gating behind a consent toggle, and remove auto-triggered AI requests on page load.
