Privacy Policy

Privacy Policy

P. Vigneau built the CardBook add-on as an Open Source app.

This page is used to inform visitors regarding my policies with the collection, use, and disclosure of Personal Information if anyone decided to use my Service.

If you choose to use my Service, then you agree to the collection and use of information in relation to this policy. The Personal Information that I collect is used for providing and improving the Service. I will not use or share your information with anyone except as described in this Privacy Policy.

The terms used in this Privacy Policy have the same meanings as in our Terms and Conditions, which is accessible at CardBook unless otherwise defined in this Privacy Policy.

CardBook presentation

CardBook is software, which allows users to integrate and manage their local or online address books. Each Thunderbird user chooses which online accounts he or she wishes to access using CardBook.

Personal Information is information that you provide to me that personally identifies you, such as your name or email address. Except as described below, CardBook does not collect or require end-users of CardBook to provide Personal Information.

When you set up CardBook to access your address books, you will need to enter information and credentials for that account, such as your name, email address, and password. CardBook stores this information on your computer in your Thunderbird profile.

To simplify the set-up process, CardBook tries to locate this information for you. During this setup process, CardBook may try to contact external DNS servers, standard autoconfiguration URIs, and CardBook’s configuration database to try and work the settings needed for your account. This may involve sending part or all of your email address, but never involves sending your password. When CardBook does this, the parties contacted may retain logs of those requests.

CardBook stores other information on your computer, including information you enter in your Thunderbird address book and copies of your contacts. CardBook stores this information on your computer in your Thunderbird profile and does not transmit it to anybody.

Cookies are files with a small amount of data that are commonly used as anonymous unique identifiers. These are sent to your browser from the websites that you visit and are stored on your device’s internal memory.

This Service does not use these “cookies” explicitly. However, CardBook may use third party code and libraries that use “cookies” to collect information and improve their services. You have the option to either accept or refuse these cookies and know when a cookie is being sent to your device. If you choose to refuse our cookies, you may not be able to use some portions of this Service.

By default, the activities of storing and sending cookies are invisible to you. However, you can change your Thunderbird settings to allow you to approve or deny cookie storage requests, delete stored cookies automatically when you close Thunderbird, and more.

Automated Update Service

Thunderbird’s automatic update feature periodically checks to see if an updated version of CardBook is available from Thunderbird, so refer to Mozilla Thunderbird Privacy Policy

This Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by me. Therefore, I strongly advise you to review the Privacy Policy of these websites. I have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Children’s Privacy

These Services do not address anyone under the age of 13. I do not knowingly collect personally identifiable information from children under 13.
