PageGuard Cursor Rule Adds Privacy Compliance Nudges
PageGuard published a Cursor IDE rule (pageguard.mdc) that detects privacy-relevant dependency changes and provides in-context compliance guidance to developers. Installed in .cursor/rules/, the rule flags additions of analytics, advertising, payment, authentication, error-tracking, session-recording, email and push SDKs, explains typical personal data collected, and suggests running the PageGuard CLI (npx pageguard) for a full scan. The PageGuard scan returns six scores (Privacy Risk Score, Security Headers, Accessibility, Performance, AI Readiness, Structured Data). The rule can be installed manually or downloaded from the PageGuard GitHub, and PageGuard's CLI works across editors (Cursor, Claude Code, any terminal). Scan results are free; PageGuard offers paid document-generation features for tailored privacy policies and remediation guidance.
Practical developer tooling that improves privacy and consent hygiene by detecting data-collecting SDKs and nudging scans; helps reduce regulatory and operational risk for web/apps but is not a platform-level policy change.

Add Privacy Compliance Scanning to Claude Code
The article explains how to embed privacy-compliance checks into Anthropic's Claude Code workflow by adding a CLAUDE.md rule that flags privacy-relevant dependency additions (analytics, advertising, payments, auth, error tracking, session replay, email, push). When such dependencies appear, Claude Code can notify developers about typical personal data collected, suggest running PageGuard (npx pageguard) for a full scan, and note likely requirements (privacy policy, cookie consent, DPA). The post also describes installing the PageGuard CLI (npx pageguard --init) and pairing CLAUDE.md rules with a PageGuard GitHub Action (AuxiliumApps/pageguard-action@v1) to catch issues in pull requests.
Five IDE Rules for Safe AI-Assisted Coding
The article describes five IDE/workflow rules to reduce risks from AI-assisted “vibe coding”: linting, consistent formatting, dependency security audits, privacy-compliance scanning, and testing. It recommends concrete tools and commands (ESLint --fix for TypeScript, Prettier with a sample .prettierrc, npm audit for dependency CVEs, vitest for unit tests) and shows how to integrate rules into AI assistants (Cursor rules, CLAUDE.md for Claude Code). The piece emphasizes privacy as a major blindspot when AI adds analytics, payments or tracking SDKs and promotes PageGuard (npx pageguard) for scanning sites and flagging privacy gaps (example output lists Google Analytics, Stripe.js, Firebase Auth, Sentry). The guidance encourages running these checks automatically inside the AI workflow so generated code ships with linting, formatting, security, compliance and tests applied.
Free DSGVO/GDPR Scanner Launched; 73% of Sites Violated
A developer, Nevik Schmidt, launched a free DSGVO/GDPR compliance scanner (nevik.de/guard) that performs server-side scans of websites for privacy and legal issues. Scanning over 200 German websites, the tool found that 73% had at least one potential compliance violation. The scanner detects external font loading (e.g., Google Fonts), common third‑party trackers (Google Analytics, Facebook Pixel, Hotjar), cookie consent setup, SSL/TLS status, presence of legal pages (Impressum, privacy policy), and server location (EU vs non-EU). The tool was built using Node.js/Express on a Hetzner VPS, uses Puppeteer for scanning, stores results in PostgreSQL, and offers a free one-off scan plus paid agency features (monitoring, PDF reports, API access planned).
