Is Custom Calendar Background Safe? — Extension Safety Profile

This extension asks for only three permissions: storage, identity, and identity.email. Storage lets it save your preferences locally. The identity and identity.email permissions allow it to sign you in with your Google account and read your email address — likely to sync your custom backgrounds across devices or personalize your experience. It does not request access to your calendar data, browsing history, or the content of any web pages, which is a very limited scope for a customization tool and explains its perfect Permissions & Access score.

For any extension that collects personally identifiable information, even just an email address, it’s wise to check the publisher’s background. The developer declares they collect PII but state it is not sold or used for unrelated purposes. However, the Publisher & Identity dimension is the weakest here, meaning the company behind “useit.today” may not be widely known or have a long public track record. A careful user should verify the publisher’s website and privacy claims before granting sign-in access.

Overall, the extension’s minimal permission requests are its strongest safety feature, while the lower publisher transparency is a point to consider. As always with browser extensions, only install from publishers you trust, especially when they can see your email address.
