When you register an account, and using SetCronJob to create your cronjobs, your informations such as email, cronjobs URL, etc will be collected and stored in database.
Information and/or data you given is your property and is protected by default.
I'll never share or publish users' informations for any third-party, include email address, password, cronjob URL.
These informations may be released only when I believe they're necessary to comply with law of my and users' country, or to protect the rights, property, or safety of SetCronJob, my users, or others.
You have the right to make SetCronJob stop sending mails to you. Simply go to My Account, and change preferences.
All emails will be sent to you from only 2 addresses: email@example.com (contact page and manually) and firstname.lastname@example.org (automatically though my system).
