Risk impact

Google Calendar Color requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install Google Calendar Color if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Google Calendar Color may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.
