Machete is Google Chrome plugin, which is embedded in your browser and runs when you visit https://ams.amazon.com. When you visit AMS, Machete takes a snapshot of your data and stores it on our servers. In the background, it continues to snapshot your data at regular intervals to get a complete history of your campaigns.
Machete runs as a browser plugin, so it's limited to things that your browser can do. That means that Machete can't gather data when any of the following are true:
No. Machete will never ask for your Amazon password. Your Machete account is handled by Login with Amazon, as described in the next question.
Login with Amazon for Machete works the same way as other sites that allow you to login with your Google, Facebook, or Twitter account: you log in at Amazon.com, then allow Amazon to share your name and email with Machete. Machete never sees your password and has no access to any other part of your Amazon account.your profile
Only your account is allowed to view the data we gather about your campaigns. All data is transferred with HTTPS to prevent snooping, and user-specific information is never shared with other users or companies.
Machete can't get data from the past, because the interface used by AMS doesn't currently support this. Therefore, Machete starts gathering historical data from the moment that it's installed. If you've just installed Machete, you will see your history data slowly fill in over the next few days.
The Machete browser plugin is open-source, and can be viewed at our GitHub repository.
