Google is introducing new Chrome Web Store policies that will require browser extensions to collect less user data, improve transparency, and comply with new restrictions related to artificial intelligence and prediction markets. The updated rules take effect on August 1, giving developers a limited window to ensure their extensions meet the new requirements.
One of the most significant changes targets data collection. Under the revised policies, Chrome extensions may only access information that is directly required to provide their advertised functionality. Google says developers can no longer collect additional user data for unrelated purposes, future features, or analytics that are not essential to the extension’s operation.
The company is also raising the bar for transparency. Developers must clearly explain what information an extension collects and why it is needed before users install it. If an extension later changes how it collects or uses data, users must receive a clear notification instead of having the changes buried in an updated privacy policy.
Google is also expanding its policies to cover emerging online services. The Chrome Web Store will prohibit extensions that facilitate real-money prediction markets, placing them under the company’s existing rules governing regulated financial services and gambling-related content.
Another new restriction focuses on artificial intelligence. Extensions designed to bypass the safeguards, usage limits, or security protections implemented by AI platforms will no longer be permitted on the Chrome Web Store. Google says the change is intended to prevent extensions from undermining the safety measures built into AI services.
The policy updates come as browser extensions continue to attract increased scrutiny from security researchers. Over the past several years, multiple investigations have uncovered extensions that requested broad permissions, collected unnecessary browsing data, or transmitted user information without adequate disclosure. Google says limiting data collection to only what is necessary will help reduce privacy risks for Chrome users.
The company is also making developers more accountable for the permissions they request. Extensions that ask for access to sensitive information must demonstrate that the permissions are required for their core functionality. Requests that exceed an extension’s stated purpose may violate Chrome Web Store policies and could lead to enforcement action.
Developers have until August 1 to review their extensions and implement the required changes. Google says extensions that fail to comply may face policy violations, removal from the Chrome Web Store, or suspension from the developer program.
