Privacy & Data Disclosures

Privacy Policy URL

Required if your extension collects any user data. Must be a publicly accessible URL.

Data Use Disclosures

Declare what data you collect, why, and whether you sell or share it. Found in the Privacy tab of the developer dashboard.

Permission Justifications

Explain why each requested permission is necessary. Vague or missing justifications are the #1 cause of review rejections.

Single Purpose

Your extension must have one clearly stated purpose. Multi-purpose extensions are rejected.

Common Rejection Reasons

Excessive permissions

Fix: Only request what you need. Remove unused permissions from manifest.json.

Missing or vague permission justifications

Fix: Write a specific sentence for each permission explaining how your extension uses it.

Remotely hosted code

Fix: Bundle all JavaScript in the extension package. No eval(), no CDN scripts.

Misleading metadata

Fix: Your name, description, and screenshots must accurately represent functionality.

Missing privacy policy

Fix: Add a privacy policy URL if you request host permissions or collect any data.

Not single purpose

Fix: Each extension should do one thing well. Split multi-purpose tools into separate extensions.
