When visiting the Website and/or using the Services, you may provide us with certain types of information, as described below. Except as described in this Policy, Fallible never collects personally identifying information from the user.

Registration (Sign-Up)

In order to use the Services, a user must first complete the registration form. During registration, a user may be required to give contact information such as first and last name, company name, address, email address, job function, phone number, mobile number, URL and/or IP addresses. We use this information to verify the ownership of servers, URL, and IP addresses, to do non-invasive informational testing of users' servers, and to contact the user about Services for which they have expressed interest. In order to use the Services, users must provide a username and password.

User Payment Information

When users order the Service, they must provide payment information (such as credit card number and expiration date). This information is used for one-time and recurring billing purposes according to the type of Services ordered and the terms pertaining thereto , and to fulfill users' orders. If we have trouble processing an order, personal information is used to contact the user. Payment information is stored in encrypted format, as more fully detailed below (see Security) and is used only to send to our credit card processor, for the purposes of collecting payment for Services rendered or to be rendered. We never make this information visible to anyone other than our credit card processor and never communicate it over a non-encrypted connection. The full credit card number is never seen by anyone inside our company, once entered and submitted, except by the credit card processor for the purposes of authorizing, clearing and reversing charges to your credit card.

Delivery of Services

Fallible's Services collect information about servers connected to the IPs or URLs given by the users during the registration process. IP's and URL's are checked to verify users' authority to require security vulnerability testing. No security vulnerability data is collected until the user requests it. Users can start and stop the Fallible's scan and data collection process by changing their settings in their Account Settings web page available on the Website to users. Fallible only collects information that can be accessed from the internet about users' computer(s) and/or that is provided by users via phone and/or e-mail and does not install software on the users' computer for this purpose.

Service Announcements

It is often necessary to send out a strictly Service-related announcement. For instance, if our Service is temporarily suspended for maintenance we might send users an email. Generally, users may not opt-out of these communications, though they can deactivate their account. However, these communications are not promotional in nature.

Customer Service Communications

We communicate with users on a regular basis via email to provide requested Services, offers, or information. In regards to issues relating to their account, we reply via email or phone.


The Website may contain links to other sites. Please be aware that we are not responsible for the privacy practices of such other sites. We encourage our users to be aware when they leave our Website and to read the privacy statements of each and every Web site that collects personally identifying information. This privacy statement applies solely to information collected by the Website.

This Privacy Policy applies to Fallible services only. We do not exercise control over the sites displayed as search results, sites that include Fallible applications, products or services, or links from within our various services. These other sites may place their own cookies or other files on your computer, collect data or solicit personal information from you.


Fallible takes reasonable measures in order to safeguard users' personally identifying information.

Payment information (such as credit card number and/or social security number) and information about the security vulnerability of users' website is protected, by using Secure Sockets Layer (SSL) software, which encrypts the aforementioned information when viewed online.

While on a secured page, such as our order form, the lock icon on the bottom of Web browsers such as Firefox and Microsoft Internet Explorer becomes locked, as opposed to un-locked, or open, when users are just surfing.

In addition, we limit access to personally identifying information to employees who we believe reasonably need to receive such information to provide our Services or in order to do their jobs and take other precautions we deem reasonable to protect the security of users' personally identifying information.

However, users should be aware that we cannot fully guarantee the security of their personally identifying information. As in many computer systems, internet applications and software programs, unauthorized use, failure of hardware or software, etc. may be injuriousness to the confidentiality of users' personally identifying information.If users have any questions about security, please contact [email protected]

Correcting/Updating/Deleting/Deactivating Personal Information

If a user's personally identifying information changes (such as zip code, phone, email or postal address), or if a user no longer desires our Service, we provide a way to correct, update or delete/deactivate users' personally identifying information. This can usually be done by emailing to [email protected]

When a request for user deletion is received, we will make all reasonable efforts to purge said data from our systems. However, due to the nature of our service, some information may not be fully removed due to backups or archived copies.

Notification of Changes

If we decide to change our privacy policy, we will post those changes to this privacy statement and other places we deem appropriate so our users are always aware of what information we collect, how we use it, and under what circumstances, if any, we disclose it. We will use information in accordance with the privacy policy under which the information was collected.
