3. How do we protect your information?
We implement a variety of security measures to maintain the safety of your personal information when you enter, submit, or access your personal information. We offer the use of a secure server. All supplied sensitive information is transmitted via Secure Socket Layer (SSL) technology and then encrypted into our databases only to be accessible by those authorized with special access rights to such systems, and are required to keep the information confidential.
4. How do we ensure that our processing systems remain confidential, resilient,
We implement a variety of measures to ensure that our processing systems remain confidential, resilient, and available. Specifically, we have implemented processes to help ensure high availability, business continuity, and prompt disaster recovery. We commit to maintaining strong physical and logical access controls, and conduct regular penetration testing to identify and address potential vulnerabilities.
a) High Availability. Every part of the App utilizes properly-provisioned, redundant servers (e.g., multiple load balancers, web servers, replica databases) in case of failure. We take servers out of operation as part of regular maintenance, without impacting availability.
b) Business Continuity. We keep encrypted backups of data daily. While never expected, in the case of production data loss (i.e., primary data stores loss), we will restore organizational data from these backups.
c) Disaster Recovery. In the event of a region-wide outage, we will bring up a duplicate environment in a different region. Our operations team has extensive experience performing full region migrations.
d) Physical Access Controls. Our website and the App are hosted on the DigitalOcean infrastructure. DigitalOcean runs on top Amazon Web Services (AWS). AWS data centers feature a layered security model, including extensive safeguards such as custom-designed electronic access cards, alarms, vehicle access barriers, perimeter fencing, metal detectors, and biometrics. According to the AWS Security Whitepaper: “AWS’s data centers are state of the art, utilizing innovative architectural and engineering approaches. Amazon has many years of experience in designing, constructing, and operating large-scale data centers. This experience has been applied to the AWS platform and infrastructure. AWS data centers are housed in nondescript facilities. Physical access is strictly controlled both at the perimeter and at building ingress points by professional security staff utilizing video surveillance, intrusion detection systems, and other electronic means. Authorized staff must pass two-factor authentication a minimum of two times to access data center floors. All visitors and contractors are required to present identification and are signed in and continually escorted by authorized staff.” Graychain employees do not have physical access to AWS data centers, servers, network equipment, or storage.
e) Logical Access Controls. Graychain is the assigned administrator of its infrastructure on the DigitalOcean infrastructure, and only designated authorized Graychain
operations team members have access to configure the infrastructure on an as-needed basis behind a two-factor authenticated virtual private network. Specific private keys are required for individual servers, and keys are stored in a secure and encrypted location.
f) Penetration Testing. We engage an independent, third-party agency to perform black box penetration testing on an annual basis. Information about security vulnerabilities that are successfully exploited through penetration testing is then used to set mitigation and remediation priorities.
g) Intrusion Detection and Prevention. Unusual network patterns or suspicious behavior are among Graychain’s biggest concerns for infrastructure hosting and management. AWS’ intrusion detection and prevention systems (IDS/IPS) rely on both signature-based and algorithm-based security to help identify traffic patterns that are similar to known attack methods. IDS/IPS involves tightly controlling the size and make-up of the attack surface, employing intelligent detection controls at data entry
points, and developing and deploying technologies that automatically remedy dangerous situations, as well as preventing known threats from accessing the system in the first place. We do not provide direct access to security event forensics, but we do provide access to our engineering and customer support teams during and after any unscheduled downtime.

In addition to placing web beacons on our own websites, we sometimes work with other companies to place our web beacons on their websites or in their advertisements. This helps us to develop statistics on how often clicking on an advertisement on a Graychain website results in a purchase or other action on
the advertiser’s website.
Finally, our App may contain web beacons or similar technologies from third-party analytics providers that help us compile aggregated statistics about the effectiveness of our promotional campaigns or other operations. These technologies enable the analytics providers to set or read their own cookies or other identifiers on your device, through which they can collect information about your online activities across applications, websites or other products.
6. Do we disclose any information to outside parties.
We share your personal data with your consent, or as necessary to make the App available to you. We also share your data with vendors working on our behalf; when required by law or to respond to legal process; to protect our customers; to protect lives; to maintain the security and integrity of our App; and to protect our rights or our property.
a) We share your personal data with your consent, or as necessary to make the App available to you. We also share personal data with vendors or agents working on our behalf for the purposes described in this Policy. For example, companies we have hired to provide cloud hosting services, off-site backups, and customer support may need access to personal data to provide those functions. In such cases, these companies are required to abide by our data privacy and security requirements and are not allowed to use personal data they receive from us for any other purpose. If you have questions or concerns about any of our vendors,
feel free to contact us at email@example.com.
b) We may disclose your personal data as part of a corporate transaction such as a corporate sale, merger, reorganization, dissolution, or similar event. Finally, we will access, transfer, disclose, and/or preserve personal data, when we have a good faith belief that doing so is necessary to:

10. Data Retention
We may retain your personal information as long as is necessary to fulfill the purposes outlined in this Policy. We will delete your personal information on request. We may, however, retain personal information for an additional period as is permitted or required under applicable laws, for legal, tax, or regulatory reasons, or for legitimate and lawful business purposes.
We will retain your personal data for as long as necessary for essential purposes such as complying with our legal obligations, resolving disputes, and enforcing our agreements. Because these needs can vary for different types of data, actual retention periods can vary significantly. The criteria we use to determine the retention periods include:
a) How long is the personal data needed to make the App available to you and/or operate our business? This includes such things such as maintaining and improving the performance of the App, keeping our systems secure, and maintaining appropriate business and financial records. This is the general rule that establishes the baseline for most data retention periods.
b) Is there an automated control, such as in the App, that enables you to access and delete the personal data at any time? If there is not, a shortened data retention time will generally be adopted.
c) Is the personal data of a sensitive type? If so, a shortened retention time would generally be appropriate.
d) Has the user provided consent for a longer retention period? If so, we will retain the data in accordance with your consent.
e) Is Graychain subject to a legal, contractual, or similar obligation to retain the data? Examples can include mandatory data retention laws in the applicable jurisdiction, government orders to preserve data relevant to an investigation, or data that must be retained for the purposes of litigation.
We will update this privacy statement when necessary to reflect customer feedback and changes to our App. When we post changes to this statement, we will revise the
“last updated” date at the top of the statement. If there are material changes to the statement or in how Graychain will use your personal data, we will notify you by posting on our Website or in the App. We encourage you to periodically review this privacy statement to learn how Graychain is protecting your information.
