The Stricter Review Landscape
The Chrome Web Store review process has grown significantly more rigorous over the past years. Reviewers now employ automated tools that scan for patterns associated with policy violations, and manual reviews dive deeper into functionality than ever before. Extensions that previously sailed through approval now face rejection for subtle policy misalignments. Understanding these rejection reasons and their fixes is essential for any extension developer.
This guide covers the most common rejection scenarios and provides actionable solutions. Each section explains what triggers the rejection, why it matters, and how to address it before submitting your extension.
Excessive Permissions
The most frequent rejection stems from requesting more permissions than your extension actually uses. The review process flags any permission that appears unnecessary for the stated functionality.
What triggers rejection: Requesting broad permissions like <all_urls> when you only need specific domains, using cookies permission for a feature that does not require cookie access, or requesting tabs permission when activeTab would suffice. The reviewer compares your manifest.json permissions against the functionality described in your store listing and source code.
How to fix it: Audit every permission in your manifest.json and confirm each one is actively used by your extension. Replace host permissions with specific domains where possible. Use the activeTab permission instead of broad URL access for features that only run when the user explicitly invokes them. For permissions needed only in specific scenarios, declare them as optional_permissions and request them at runtime using the Permissions API. The @theluckystrike/webext-permissions library simplifies this pattern by providing a clean interface for requesting permissions on demand rather than upfront.
Missing Privacy Policy
Extensions that collect any user data must include a comprehensive privacy policy. This requirement applies to any extension using storage, cookies, identity, webRequest, or any host permissions.
What triggers rejection: Submitting without a privacy policy URL in the Developer Dashboard, or submitting a policy that fails to disclose what data your extension collects, how it stores that data, and whether it shares data with third parties.
How to fix it: Create a dedicated privacy policy page on your website and link it in the Developer Dashboard under the Privacy Practices section. Your policy must clearly state what data your extension collects (if any), how that data is used, whether it is stored locally or transmitted to external servers, and whether you share data with third parties. For extensions that do not collect any user data, state this explicitly. Reference the privacy policy template in this guide for a comprehensive starting point.
Remote Code Execution Detection
Chrome Web Store prohibits extensions that execute remote code. This policy exists to protect users from malicious modifications that could occur after the extension passes review.
What triggers rejection: Using eval() or new Function() in your extension code, loading scripts dynamically from external URLs via <script src="...">, passing arbitrary strings to chrome.scripting.executeScript(), or constructing and executing code at runtime. Reviewers actively search for these patterns using static analysis.
How to fix it: Bundle all JavaScript code locally within your extension package. Use chrome.scripting.executeScript with the files parameter only, never with code strings. Implement a strict Content Security Policy in your manifest.json that blocks unsafe-eval and restricts script sources to local files only. If you need to load configuration data, use JSON files bundled with your extension rather than fetching them at runtime.
Deceptive Functionality
Your store listing must accurately represent what your extension actually does. Any discrepancy between the listing description and the actual functionality raises red flags for reviewers.
What triggers rejection: Promising features in your description that your extension does not provide, using misleading screenshots that show functionality removed in the current version, or including feature lists that do not match the actual user experience.
How to fix it: Review your store listing description and ensure every feature mentioned is present and functional in the current version. Use screenshots that accurately depict the actual extension interface. Remove any references to features that were cut or never implemented. If your extension has limitations, disclose them honestly in the description.
Missing or Unclear Purpose
Extensions must serve a clear, identifiable purpose. Reviewers reject extensions that appear to do too much or whose purpose remains ambiguous.
What triggers rejection: Building an extension that combines unrelated features (for example, a productivity tool that also modifies web pages and displays weather information), failing to articulate the core purpose in your store listing, or creating an extension whose functionality does not align with any clear use case.
How to fix it: Define a single, coherent purpose for your extension and ensure all features support that purpose. If you have multiple distinct features, consider splitting them into separate extensions, each with its own clear focus. Your store listing should open with a clear statement of what your extension does and why it is useful.
User Data Policy Violation
Chrome Web Store has strict requirements around how extensions handle user data. Violations here can result in permanent suspension in severe cases.
What triggers rejection: Collecting user data without explicit disclosure, transmitting data to external servers without consent, storing sensitive information insecurely, or failing to honor user requests to delete their data.
How to fix it: Disclose all data collection in both your privacy policy and within your extension’s UI. Prefer local storage via chrome.storage over external servers when possible. The @theluckystrike/webext-storage library provides a clean abstraction for local storage operations. If you must send data to external servers, implement secure transmission (HTTPS) and obtain clear user consent. Provide users with the ability to export and delete their data.
Notification Abuse
Extensions that abuse the notification system face swift rejection. This includes spam notifications, notifications that persist inappropriately, or notifications that redirect users to external sites without clear value.
What triggers rejection: Using the Notifications API to send promotional content, displaying notifications at excessive frequency, using notifications to drive traffic to monetization pages, or failing to respect system notification settings.
How to fix it: Limit notifications to essential updates that directly relate to your extension’s core purpose. Never use notifications for promotional or marketing purposes. Provide clear notification settings within your extension that allow users to control frequency and content. Test your notification behavior to ensure it does not annoy users or trigger system spam filters.
The Appeal Process
When your extension receives a rejection, you have the opportunity to appeal. A well-crafted appeal can reverse rejections based on misunderstandings or provide context that clarifies your implementation.
How to appeal: Navigate to your extension in the Developer Dashboard and locate the rejection notice. Click the option to submit an appeal. Provide a clear explanation of why your extension complies with the policy in question. Include specific details about your implementation that address the rejection reason.
What to include: Reference the exact policy that was flagged and explain how your implementation satisfies that policy. If the rejection seems based on a misunderstanding, provide clear technical details that clarify your approach. Include screenshots that demonstrate your implementation, particularly for permission-related rejections where the feature requiring the permission might not be obvious from code alone.
Best practices: Respond promptly to rejection notices, as delaying your appeal extends your time to market. Be respectful but firm in your justification. If you made changes to address the rejection, clearly describe those changes. Expect review times of several days to over a week for appeals.
Pre-Submission Checklist
Before submitting any extension to the Chrome Web Store, work through this checklist to minimize rejection risk.
Review your permissions and confirm each one is actively used by your extension. Remove any unused permissions. Replace broad host permissions with specific domains where possible. Consider using optional_permissions for features that only need certain permissions occasionally.
Verify that your privacy policy is live on your website and accurately describes all data collection. Confirm the privacy policy URL is correctly entered in the Developer Dashboard.
Ensure all code is bundled locally with no remote script loading. Check for any eval() calls or dynamic code execution patterns. Verify your Content Security Policy in manifest.json blocks unsafe practices.
Confirm your store listing description accurately reflects your extension’s actual functionality. Remove any features mentioned that are not present in the current version.
Test your extension thoroughly on Chrome stable. Verify all features work correctly and handle errors gracefully. Check that notification behavior is appropriate and respects user preferences.
Review your screenshots and ensure they show the current version of your extension interface. Remove any outdated or misleading images.
Document a single, clear purpose for your extension. Confirm all features align with that purpose and nothing extraneous is included.
