Your privacy is important to us. It is Monster Endeavors, LLC's policy to respect your privacy and comply with any applicable law and regulation regarding any personal information we may collect about you, including across our website, slackletter.com, and other sites we own and operate.

Personal information is any information about you which can be used to identify you. This includes information about you as a person (such as name, address, and date of birth), your devices, payment details, and even information about how you use a website or online service.

In the event our site contains links to third-party sites and services, please be aware that those sites and services have their own privacy policies. After following a link to any third-party content, you should read their posted privacy policy information about how they collect and use personal information. This Privacy Policy does not apply to any of your activities after you leave our site.

How Long We Keep Your Personal Information

We keep your personal information only for as long as we need to. This time period may depend on what we are using your information for, in accordance with this privacy policy. If your personal information is no longer required, we will delete it or make it anonymous by removing all details that identify you.

If you terminate or delete your account, we will delete your personal information within 30 days of the deletion of your account.
