However, multiple reviews highlight missing features such as a delete button, automatic clearing of results upon closing, limited input length, and the absence of thousand separators, which impact usability.

とても使い易く便利。しかし電卓を閉じても前回の計算結果が残っているので、毎回Cを押して消さなければならない。電卓を閉じたら計算結果をクリアして欲しい。 Very easy and convenient to use. However, when I close the calculator, the result of the previous calculation is still there, so I have to press C to delete it each time. I would like the calculation results to be cleared when the calculator is closed.

Extension safety

Risk impact

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, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Calculator does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

Risk likelihood

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.

Calculator has earned a good reputation and can be trusted.
