Note that running Atom Logger on your own computer is perfectly legal but you have to warn other computer users that their activities are being monitored.
The logger can be used to received keylogs via SMTP (email) or FTP (direct upload to your website). Note that email notification on specific keywords are only sent via SMTP.
Between the extras that are linked to Atom Logger you will find an usage guide that I recommend to read before starting to create your builds. It will help you to understand how the builder/logger works.
Keyloggers are designed to monitor what happens (especially what's being typed) on computers. Using this kind of tool on your own device is perfectly legal but you need owner approval to run it on other ones.
Purchasing the Atom Logger + Rogue Miner bundle you will get both my keylogger and silent miner with a 20% off on the final price. The logger can be used to drop and run the miner on specific computers.
