Personal Information and Data We Collect

When you visit the Site, we automatically collect certain information about your device, including information about your web browser, IP address, time zone, and some of the cookies that are installed on your device. Additionally, as you browse the Site, we collect information about the individual web pages or products that you view, what websites or search terms referred you to the Site, and information about how you interact with the Site. We refer to this automatically-collected information as “Device Information.”

We collect Device Information using the following technologies:
• “Cookies” are data files that are placed on your device or computer and often include an anonymous unique identifier. For more information about cookies, and how to disable cookies, visit
• “Log files” track actions occurring on the Site, and collect data including your IP address, browser type, Internet service provider, referring/exit pages, and date/time stamps.
• “Web beacons,” “tags,” and “pixels” are electronic files used to record information about how you browse the Site.

Additionally when you make a purchase or attempt to make a purchase through the Site, we collect certain information from you, including your name, billing address, shipping address, payment information (including credit card numbers), email address, and phone number.

By their own nature, FDS Logbook and many Freefall Data Systems devices are designed to collect data pertaining to a jumper’s skydives, BASE jumps, and wind tunnel body flight training. In FDS Logbook, four pieces of personal data are collected as well: the user’s name, phone number, email, and highest license number. Whenever Freefall Data Systems collects data, whether for taking payment or for logging or any other purpose, that information is encrypted and transmitted to us in a secure fashion. Data can be collected through direct input into FDS Logbook by a user, or can be collected automatically by devices such as altimeters, where the data collected is then synced by a user to FDS Logbook via a mobile device. Freefall Data Systems LLC (henceforth FDS) believes strongly in a consumer’s rights to data protection and pledges to never sell or divulge any gathered data in FDS Logbook to a third party unless required by law. The data collected may, however, be used in an anonymous form (i.e. without using any information publically that would reveal a particular jumper’s identity) for the purposes of product development and improvement, analysis, advertisement and display. FDS requires access to data in its database in order to diagnose problems and determine potential improvements to logging devices as well. All data collected through FDS Logbook is stored in Google's Firestore database.

FDS Logbook has several social media features. Users can choose to opt out of this entirely, making the logbook effectively private, simply by not accepting any follower or instructor requests. There is no master list of all users that can be viewed online. However, to enable the possibility of networking, each user’s name can be found by entering another user’s first and last names in a search, which reveals the user’s profile image as well. A profile image and name should therefore necessarily be considered public and accessible by a third party. These are actually the only elements that are publicly viewable in FDS Logbook, and one is required to have a profile oneself in order to view others’ profiles as well. Those who choose to network by adding followers or instructors can choose to hide or show three of the four personal pieces of information mentioned above: their email addresses, phone numbers, and/or highest license number. This can be done under Preferences in one’s profile. Followers can view a user’s logbook but cannot edit them. Instructors can both view and edit a user’s logbook with the exception of their Profile, Preferences and Associates.

It is important to realize that in contrast to skydiving and tunnel training, BASE jumping is currently illegal in the majority of locations it is carried out. Logging BASE jumps can help one learn and keep track of one’s progress, but a logbook could also be used as evidence in a criminal proceeding. Freefall Data Systems LLC is against the general stigmatization of BASE jumping and many of the unreasonable laws designed to inhibit people from engaging in it. We will always stand up for the BASE community in this regard. In the case of a subpoena, however, FDS would be obliged to divulge any information legally required by the state or federal government. All logging is at the user’s own risk.

This website and in particular FDS Logbook contains links to other sites (e.g. YouTube, Facebook, Instagram, and Shopify). Please be aware that we are not responsible for the content or privacy practices of such other sites. We encourage our users to be aware when they leave our site and to read the privacy statements of any other site that collects personally identifiable information.

When we talk about “Personal Information” in this Privacy Policy, we are talking both about Device Information and Order Information.
