Vendors, Consultants, and Other Third-Party Service Providers. We may share your data with third-party vendors, service providers, contractors, or agents (“third parties“) who perform services for us or on our behalf and require access to such information to do that work. We have contracts in place with our third parties, which are designed to help safeguard your personal information. This means that they cannot do anything with your personal information unless we have instructed them to do it. They will also not share your personal information with any organization apart from us. They also commit to protect the data they hold on our behalf and to retain it for the period we instruct.
The categories of third parties we may share personal information with are as follows:
- Data Analytics Services
- Payment Processors

We also may need to share your personal information in the following situations:
- Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
- When we use Google Maps Platform APIs. We may share your information with certain Google Maps Platform APIs (e.g., Google Maps API, Places API). Google Maps uses GPS, Wi-Fi, and cell towers to estimate your location. GPS is accurate to about 20 meters, while Wi-Fi and cell towers help improve accuracy when GPS signals are weak, like indoors. This data helps Google Maps provide directions, but it is not always perfectly precise.
4. WHAT IS OUR STANCE ON THIRD-PARTY WEBSITES?
In Short: We are not responsible for the safety of any information that you share with third parties that we may link to or who advertise on our Services, but are not affiliated with, our Services.
The Services may link to third-party websites, online services, or mobile applications and/or contain advertisements from third parties that are not affiliated with us and which may link to other websites, services, or applications. Accordingly, we do not make any guarantee regarding any such third parties, and we will not be liable for any loss or damage caused by the use of such third-party websites, services, or applications. The inclusion of a link towards a third-party website, service, or application does not imply an endorsement by us. We cannot guarantee the safety and privacy of data you provide to any third-party websites. Any data collected by third parties is not covered by this Privacy Notice. We are not responsible for the content or privacy and security practices and policies of any third parties, including other websites, services, or applications that may be linked to or from the Services. You should review the policies of such third parties and contact them directly to respond to your questions.
We may use cookies and similar tracking technologies (like web beacons and pixels) to gather information when you interact with our Services. Some online tracking technologies help us maintain the security of our Services, prevent crashes, fix bugs, save your preferences, and assist with basic site functions.
We also permit third parties and service providers to use online tracking technologies on our Services for analytics and advertising, including to help manage and display advertisements, to tailor advertisements to your interests, or to send abandoned shopping cart reminders (depending on your communication preferences). The third parties and service providers use their technology to provide advertising about products and services tailored to your interests which may appear either on our Services or on other websites.
Specific information about how we use such technologies and how you can refuse certain cookies is set out in our Cookie Notice: https://mezzalyn.com/privacy-policy-eu/.

6. HOW LONG DO WE KEEP YOUR INFORMATION?
In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this Privacy Notice unless otherwise required by law.
We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). No purpose in this notice will require us keeping your personal information for longer than 90 days.
When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
7. HOW DO WE KEEP YOUR INFORMATION SAFE?
In Short: We aim to protect your personal information through a system of organizational and technical security measures.
We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.
8. DO WE COLLECT INFORMATION FROM MINORS?
In Short: We do not knowingly collect data from or market to children under 18 years of age.

By using the Services, you represent that you are at least 18 or that you are the parent or guardian of such a minor and consent to such minor dependent’s use of the Services. If we learn that personal information from users less than 18 years of age has been collected, we will deactivate the account and take reasonable measures to promptly delete such data from our records. If you become aware of any data we may have collected from children under age 18, please contact us at lisbon@mezzalyn.com.

You can withdraw your consent at any time by contacting us by using the contact details provided in the section “HOW CAN YOU CONTACT US ABOUT THIS NOTICE?” below.
However, please note that this will not affect the lawfulness of the processing before its withdrawal nor, when applicable law allows, will it affect the processing of your personal information conducted in reliance on lawful processing grounds other than consent.
Cookies and similar technologies: Most Web browsers are set to accept cookies by default. If you prefer, you can usually choose to set your browser to remove cookies and to reject cookies. If you choose to remove cookies or reject cookies, this could affect certain features or services of our Services. You may also opt out of interest-based advertising by advertisers on our Services.

10. CONTROLS FOR DO-NOT-TRACK FEATURES
Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track (“DNT”) feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.
