We only process your personal data for the purposes of this Data Protection Declaration. The transfer of your personal data to third parties for purposes other than those mentioned above will not take place. We will only pass your personal data to third parties when:

Erasing or blocking data

We comply with the principles of data leak prevention and data savings. We therefore retain your personal data only for as long as it is necessary to achieve the purposes stated herein or as determined by different legal periods of retention. After the end of the relevant purpose or the expiry of these deadlines, the relevant data will be blocked or removed in a standard manner and in accordance with legal provisions.


We use so-called cookies on some sites. Cookies are small text files that are transferred from the web server to your computer's hard drive. This automatically gives us certain information, such as the IP address, the browser used, the operating system, and the Internet connection. Cookies cannot be used to run programs or to transfer viruses to your computer.

The data collected by us will in no case be passed on to third parties or linked to personal data.

You can also browse our website without cookies. Internet browsers are regularly set to accept cookies. In general, you can disable the use of cookies at any time by setting up your browser. Use the Browser Help feature to see how to change these settings. Please note that the internal areas of your account or access to the mailing lists of individual features of our website may not work if you have disabled the use of cookies.

To serve our services, we've shown ads on some sites. The advertising agency (Google Adsense) uses its own cookies. We will keep you in touch with you in more detail.

Registration on our website

When registering (opening an account, gaining CAcert membership, mailing list, bug tracking, wiki editing), some personal information will be collected:

If you are registered, you can access content and services that we only offer to registered users: viewing data, creating certificates, etc. Registered users also have the option of changing or deleting the registration data at any time. Of course, we also give you at any time information about the personal information we have about you. We are pleased to have it repaired or removed at your request, unless it is impeded by any Policies or statutory storage requirements.

SSL Encryption

To protect your data during transmission, we use the latest encryption technology (such as SSL/TLS) in HTTPS.

Wiki and Blog

If users leave comments on our blog or if they post to our wiki, they save not only the name or nickname, but also the creation time. This serves our security as we can be prosecuted for any illegal content on our website, even if it is created by users.

Receive emails

If you have registered for one or more conferences, you will receive the corresponding items electronically. Based on your explicit consent in your account, we will send you irregular regional reports or similar information by email to the specified email address.

To receive these emails, it is sufficient to enter your e-mail address. When you sign in to receive these emails, the information you provide will only be used for that purpose. Participants may also be informed by e-mail of service or registration circumstances (such as bid changes or technical conditions). For effective registration, we need a valid email address. To verify that the owner of the appropriate email address has actually signed up, we use the "Double opt-in" procedure. We therefore record the order of the newsletter, sending the confirmation message and receiving the required response. Other data is not collected. The data will only be used for registration and will not be passed on to third parties.

You may at any time revoke your consent to the storage of your personal data and its use for sending by logging out of the mailing lists directly to and removing a check from your local account information. The Privacy Officer or Support does not have access to your account. However, if you have problems leaving the list, they can guide you.

Contact form

If you have any question via email or if you use the contact form, you are giving us your consent to use your address for your reply. This requires a valid email address. This is used to assign a query and a subsequent response. Specification of additional data is optional. The information you provide will be stored for the purpose of processing queries and possible follow-up questions. Once the request is processed, we will automatically remove personal information. If you are sending a request to a public conference, the copy will be sent to all members of the list and archive. Deleting these recipients by CAcert is not technically possible.

Changing our Data Protection Declaration

We reserve the right to modify these Data Protection Declaration to comply with the latest legal requirements or to make changes to our privacy policy, such as when introducing new services. The current privacy protection already applies to your new visit.

Data Protection Declaration for PayPal Payment Service

PayPal has certain components integrated on your website. PayPal is a payment service provider online. Payments are made through so-called PayPal accounts, which are virtual private or corporate accounts. In addition, PayPal has the ability to process virtual payments via payment cards if the user does not have a PayPal account. PayPal is managed through an email address and therefore does not have a classic account number. PayPal allows you to initiate online payments to third parties or receive payments. PayPal also takes over administrator functions and offers buyer protection services.

European Operational Society of PayPal is

If the responsible person [the buyer] selects a "PayPal" payment order during the order process in our online store, the data on this person will be automatically sent to PayPal. By selecting this payment option, the person in question agrees to transfer the personal data needed to process payments. Personal information sent to the PayPal service is usually a name, surname, address, email address, IP address, phone number, mobile phone number and other data needed to process payments. To complete the purchase agreement, you also need personal information related to your order.

The purpose of data transfer is to process payments and to prevent fraud. The responsible person's personally identifiable information will be provided to the PayPal service, especially if there is a legitimate interest in the transfer. Personal information exchanged between PayPal and the responsible person can be transferred to intelligence services. This transmission is focused on the identification and control of credibility.

PayPal may disclose personal data to affiliates and service providers or subcontractors to the extent necessary to perform their contractual obligations or process data on behalf of the Company.

The responsible person has the option of withdrawing at any time the consent to the processing of personal data by the PayPal service. The appeal has no effect on the personal data that must be processed, used or transferred to the contractual processing of payments. PayPal's applicable Data Protection Declaration can be found here.
