Frequently Asked Questions

How are privacy risk scores calculated?▾
Each script is rated 1-5 based on the type and amount of data it collects, whether it shares data with third parties, its data jurisdiction, and whether it uses cookies or fingerprinting. A score of 5 means extensive cross-site tracking and data sharing.
How accurate are the KB and ms estimates?▾
The estimates are based on typical script sizes and blocking times measured across many sites. Actual values vary depending on configuration, caching, and network conditions. They provide a directional guide for optimization priorities.
What does each recommendation mean?▾
Keep: script is acceptable. Optimize: reduce impact through lazy loading or configuration. Replace: switch to a lighter or more privacy-friendly alternative. Remove: script has high risk with limited value -- consider removing it entirely.
How are the grades calculated?▾
Privacy grade is based on average risk score across all detected scripts (A=best, F=worst). Performance grade is based on total script weight in KB. Both use standard grading thresholds.
Why does consent matter for performance?▾
Scripts requiring consent cannot load until the user accepts cookies. This creates two problems: users who reject get no tracking (data loss), and users who accept experience delayed script loading (performance hit).
What are good alternatives for high-risk scripts?▾
For analytics, use Plausible or Zenovay (no cookies, GDPR-compliant). For session recording, Microsoft Clarity is free and lightweight. For advertising pixels, use server-side conversion APIs to reduce client-side impact.
