When does my personal information get deleted?

We delete your personal information when the purpose for which it was collected no longer exists; this could include information collected during the execution of a contract which has been terminated. In order to adhere to trade/tax law and other legal obligations, it may be necessary to store your personal information beyond the purpose for which it was collected, or to initially block the information so that it can be used for later processing. This may also be necessary for the assertion, exercise and defence of legal claims.

How does ZEISS safeguard my personal information?

When you sign in to specially protected areas, e.g. via ZEISS ID, or into online shops, when you register to participate in contests or when you place an order, your personal information is transferred to us. To ensure that your information does not end up in the wrong hands, it is encrypted using standard, state-of-the-art methods such as SSL encryption (secure sockets layer). This is a proven and secure method of transferring information on the Internet.

ZEISS also employs a wide range of additional technical and operational security measures to ensure the safeguarding of personal information for its partners and customers. In conjunction with these security measures, we may occasionally request that you provide proof of your identity before granting you access to your personal information.

Falsified emails (spoofing), spam and phishing

Beware of phishing and spoofing activities

Unfortunately, the ZEISS brand is among those which are misused for deceptive purposes. In more specific terms, this means that users sometimes receive falsified emails supposedly sent from ZEISS. These emails are often visually designed to look like ZEISS communications and can in some cases be difficult to tell apart from authentic emails from ZEISS.

In these cases, the persons sending the falsified emails are attempting to exploit the trust between ZEISS and its customers in order to steal sensitive information (e.g. login details, customer information, payment information) or to install malicious software on your computer or smartphone.

These emails are not created or sent by ZEISS, even if our name is used to make it appear so. Unfortunately, this also means the ZEISS has no control over the creation and sending of illegitimate emails.

The following characteristics can help you identify whether the email you received is actually from ZEISS:

  • Confirmation emails and invoices from ZEISS should only be for items you actually ordered.
  • Emails from ZEISS should be free of typographical and grammatical errors, since they are proofread before being sent.

In some areas of our websites, we also provide information about, and links to, third-party websites. We do this only if we are firmly convinced of the seriousness of the respective supplier. However, ZEISS is not responsible for the data protection stipulations or contents of these websites and assumes no liability in this regard. These external links are marked with the following icon:

The right way to deal with spam, phishing and spoofing emails:

  • We recommend that you delete suspicious emails immediately.
  • Never open links or attachments in suspicious emails and never give out your personal information.
  • We also recommend running a virus scan on your computer.

If an email contains unusual or suspicious information regarding your order or your customer information, sign into the online shop with which you placed the order. There, you will find a list of all the orders you have actually placed, along with the status and invoice number for each order. To do this, manually enter the address for the ZEISS website or platform in your browser. Manually entering the address allows you to avoid the risk of being sent to fraudulent websites via links contained in the email.

Tip: If you're unsure about an email you've received, use our contact service to get in touch with us or write us a message at View form

Important information about the safeguarding of your information

Safeguarding your personal information

In today's connected world, unauthorized attempts to access information are a reality which private individuals and companies are confronted with on a daily basis. Safeguarding information against such attempts is a considerable challenge.

Data protection is a high priority issue at ZEISS, and we invest time, energy and money into ensuring that our systems are secure and monitored around the clock. When you use ZEISS websites and platforms, you entrust us with your personal information. Safeguarding this information is important to us. There are also things that you can do to protect your personal information against unauthorized access. Below you will find information about how you can help ensure that your information stays safe.

How can I protect my personal information?

The rule of thumb here is to protect the information on your computer, laptop and mobile devices with passwords and PIN codes that only you know. Also, make sure you sign out of ZEISS websites, platforms and shops after you are finished using them.

Make sure that you only use one unique password per account. Never use the same password for different service providers or online portals. Check to make sure that the passwords you use on ZEISS websites and platforms are not being used for other websites as well. If they are, we recommend changing all of your ZEISS passwords immediately.

Do not write your passwords down where other people can see them. Once again, make sure that you are the only person who has access to these passwords.

How do I create secure passwords?

You want to make sure that your passwords are not easy to guess. This means not using common, everyday words, your own name or the names of family members in your passwords. For added security, it is a good idea to use a combination of upper and lowercase letters, numbers, and special characters.

Is there anything else I should know?

If you use a public computer to access ZEISS websites or platforms, be sure to sign out of your account when you are finished.

If you receive unsolicited emails asking you to provide your password or payment information, ignore these and contact ZEISS immediately (contact formular). We will look into the matter.

Data Protection Notice

Data processing at ZEISS (e.g. collection, processing, transfer) is performed in accordance with the law. The personal information needed from you for business transactions is stored by us and transferred to service providers contracted by ZEISS to the extent necessary to process the transactions.


This data protection notice applies to websites, domains, social media platforms and applications belonging to companies in the ZEISS Corporate Group (hereinafter referred to as ZEISS). They do not apply to the websites of ZEISS companies that, for example, have amended data protection and legal notices due to national legislation. Therefore, please note the respective data protection and legal notices of all ZEISS websites you visit or programs you use.

In some cases, ZEISS websites also contain links to websites of third-party, ZEISS-external companies to which this data protection and legal notice does not apply.

General Data Protection Standard

ZEISS is a corporation operating on a global scale which has cross-border legally independent companies, business processes, management structures, and technical systems.

When you visit our websites, data may be collected which may, in some cases, be of a personal nature. In this notice, we point out what personal information ZEISS companies collect during your visit to our websites, and how we handle this data.

We consider the protection of your personal information a very serious matter. Our processing of your personal information collected during your visit to our websites is carried out fully in accordance with the relevant legal stipulations. In addition, our approach to dealing with personal information is based on the EU data protection principles which provide for the greatest possible degree of transparency, observance of the right to choose, access rights and the transmission and lawful processing of personal information.

Every ZEISS company complies with the data protection laws which are applicable in its own particular case. In addition, the handling of personal information is specified in a company directive for all ZEISS companies within the Group. This ZEISS company directive serves to ensure that your data is processed properly and in compliance with the applicable laws at the ZEISS companies which handle personal information. At the same time, we have instructed our employees to refer to and comply with our data protection rules wherever personal information is requested on any website.

To the extent legally permissible and with due regard for your legitimate interests in excluding the transmission or use of information, we may forward your address and creditworthiness data to, or request this data from, credit agencies in order to run credit checks for orders.
For orders paid for by invoice, and installment purchases, we use address data in addition to other creditworthiness data to estimate the risk of payment defaults in individual cases.
ZEISS and other companies in the ZEISS Group generally provide their customers with the option of using insecure payment methods (e.g. paying by invoice, credit purchases). The following is a non-exhaustive list of companies in the ZEISS Group:

  • Carl Zeiss Industrielle Messtechnik GmbH
  • Carl Zeiss Spectroscopy GmbH
  • Carl Zeiss Meditec Vertriebsgesellschaft mbH
  • Carl Zeiss Vision GmbH
  • Carl Zeiss Microscopy GmbH

Companies which offer their customers the option of using insecure payment methods have a justified interest in protecting themselves against payment defaults. This is usually done by checking the customer's creditworthiness before offering the option of using an insecure payment method. For credit checks, ZEISS is entitled to use negative creditworthiness information about the customer that it has collected itself or which has been transferred to it by another company in the ZEISS Group.

ZEISS is also entitled to transfer negative creditworthiness information about the customer to other companies in the ZEISS group before these other companies offer the customer the option of using an insecure payment method.

Creditworthiness information pertains to information about outstanding payments and information which provides direct indication that the customer is at risk of defaulting on his or her payment (e.g. bankruptcy, debt counseling, deferrals due to inability to pay). Before ZEISS stores the collected negative information about outstanding payments for the purpose of transferring this information to other companies in the ZEISS Group, the customer will receive notice that this information may possibly be transferred. ZEISS is also entitled to transfer information about exceedingly atypical orders (e.g. simultaneous orders for multiple items with the same delivery address placed using different customer accounts) to other companies in the ZEISS Group and to use information about exceedingly atypical orders that it has received from other companies in the ZEISS Group. This is intended to prevent the occurrence of payment defaults and to protect our customers against having their identities used for fraudulent purposes.

Furthermore, ZEISS is permitted to collect and process address and order information for its own marketing purposes. This means, for example, that ZEISS may compare email addresses collected during order processes with Facebook Ireland Limited's email address lists in order to display personalized advertisements to the owner of the address. Facebook Ireland Limited is not permitted, however, to use the email address for any purpose other than comparing it with its address list. Information is sent to third parties for advertising purposes only in cases where it is legally permissible to do so.


You may object to the use, processing, and transfer of your personal information at any time by means of an informal written letter addressed to ZEISS or via email (withdrawal form). Upon receipt of your objection, we will cease to use, process, and transfer the information in question for any purpose other than carrying out the orders and tasks you have requested; we will also cease to send you advertising and promotional materials.

Disclosure or objection:

Want to know which of your personal information is processed by ZEISS? Want to object to having your information used?
According to Article 15 of the Basic Regulation on Data Privacy Protection, or according to Article 34 of the Federal Data Protection act (Bundesdatenschutzgesetz, BDSG) of 2017, this is your legal right, and we would be more than happy to fulfil your request.

When transferring personal information to these third parties, we restrict ourselves to the information which is necessary for the provision of the service in question and we ensure that this transfer is carried out in compliance with the required data security. ZEISS companies will only transfer your personal information to third parties which have committed themselves to data protection and to the processing of your information in compliance with the applicable laws.

  2. If there is no legal basis for the processing of your personal information by ZEISS and you request that ZEISS cease processing your information; 
  3. If ZEISS no longer needs your personal information, but you claim that ZEISS must store this information so that legal claims can be raised or exercised, or so that the claims of third parties can be defended; 
  4. If you object to the processing of your personal information by ZEISS (on the basis of ZEISS' legitimate interest), for the length of time required to verify if ZEISS' interest in processing your personal information takes precedence or if a legal requirement to store the information exists.

Informationen on Data Security

ZEISS understands the importance of the protection and discreet handling of the information which you transfer to us via the Internet. Data security on our websites is a top priority.

ZEISS endeavors to update its encryption technology on a continuous basis in line with technical progress, in order to guarantee the confidential handling of the information you send us over the Internet.

We use different technologies for authentication, to simplify navigation, and to improve usability. These technologies include “cookies” which measure the use and efficacy of a website. A cookie is a data item which a website sends to your browser. It is stored on your system and is used to identify it (see Cookies, Web Tracking and Web Analytics).

Visitors' IP addresses are captured on our websites for the analysis of malfunctions, for website administration, and for the attainment of demographic characteristics.

Cookies, Web Tracking and Web Analytics

ZEISS online services use cookies, pixels and other similar technologies (collectively, "cookies") to recognize your browser or device, to learn more about your interests and to provide you with essential functions and services as well as for other purposes.

Cookies have the advantage that they enable you to use many of our offers (services/features).

In certain cases, the data collected can be used to identify the visitor. The data collected is used to improve the offering or target customers. IP addresses are generally shortened or only processed in an anonymous form.

Depending on their function and purpose, cookies can be grouped into different categories: strictly necessary cookies, functional cookies, performance or analytical cookies, cookies for marketing purposes and social media cookies.

Strictly Necessary Cookies
Strictly necessary cookies are needed to allow you to navigate through a website and use the features built into it. Without these cookies, the website's functionality cannot be guaranteed. This means that certain actions performed by the user (e.g. text input, configuration options) are not stored as the user navigates to other pages on the website.

Functional Cookies
Functional cookies make it possible for a website to store information provided by the user (e.g. username, language selection, current location) to improve their browsing experience and personalize the functionality of the website. For example, a website can provide the user with local pricing information if a cookie is used to store the region that the user is in. Functional cookies are also used to perform commands such as playing videos. These cookies collect information in anonymous form and cannot be used to track your use of other websites.

Performance Cookies
Performance cookies are used to collect information about how a website is used (e.g. information about which pages the visitor visits most frequently and whether or not the user receives any error messages). These cookies do not store any information which could be used to identify the user. The collected information is aggregated and anonymized. These cookies are used exclusively to improve the performance of the website and, hence, the user's experience.

Cookies for Marketing Purposes
Cookies for marketing purposes are used to present users with advertising which is relevant to them and which is tailored to their interests. They are also used to limit the number of impressions of an ad and to measure the effectiveness of advertising campaigns. They register whether a user has visited a page or not. This information can then be shared with advertisers. These cookies are used to improve the relevance of advertising and are linked in part to page features from third parties.

Social media
As an example, we use social media cookies to activate social media plug-in icons. This also allows access to social media, and surfing on our and other websites can be tracked by the operator of the social network.

If you deactivate all cookies in your browser, neither ZEISS nor third parties will transmit cookies to your browser. However, once you have done this, you may need to manually adjust some settings each time you visit a website, and some features and services may not work.

Using Social Plug-ins

Some ZEISS websites feature the following social plug-in buttons for other websites:

These buttons, if displayed on the website, do not establish any contact with the servers from Facebook, Google+, Twitter or similar online service providers. For a connection to be activated, and for communication with Facebook, Google+ and Twitter to be established, you must firstly grant your approval – by clicking on the buttons.

If you are already logged into a social network of your choice, this is carried out without another window being opened. As this transfer occurs directly, we do not obtain any knowledge of the data transferred. What is transferred is the fact that you have launched the respective site. Insofar as you are simultaneously logged onto Facebook or other social media platforms, this information will be assigned to your social media account and will thus be connected with you.

With regard to the further use and storage of your personal data by Facebook, Google+ and Twitter, please obtain the relevant information directly from these social media companies. It is likewise possible to block social plugins through your browser using add-ons.


We use the Facebook "Customer Audience" and "Facebook Pixel" services on our websites to optimise our advertising offers provided that you have granted an appropriate consent.
For more information about these Facebook services and the privacy policy of Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland ("Facebook"), please visit
If you use a Facebook user account, the Facebook Pixel on our web pages can recognise this by the Facebook cookie which is used to transmit the usage data it has collected to Facebook for analysis and marketing purposes. Under certain circumstances, the Facebook Pixel may enable tracking on many other websites. You can check and/or deactivate this data collection and the additional processing and use of the data by Facebook directly on Facebook. With Facebook Pixel, the following data is transmitted to Facebook:

  • HTTP header information (including IP address, web browser information, web page location, document, web page URL, web browser user agent, and date and time of use)
  • Pixel-specific data: this includes the Pixel ID and Facebook cookie data including your Facebook ID (this data is used to associate events with a specific Facebook ad account and associate them with a Facebook user)
  • Additional information about your visit to our websites, as well as standard and customised data events.
    • Orders placed (sales transactions)
    • Completed registrations and trial subscriptions
    • Searched products, request for product information

The above data processing only applies to users who have a Facebook account or have requested a Facebook partner page (where a cookie was set). Playing advertising on Facebook (partner) pages using the "Customer Audience" service does not concern users who are not members of Facebook. If the Facebook ID contained in a Facebook cookie can be assigned to a Facebook user, then Facebook will assign this user to a target group ("Custom Audience") according to the rules we have defined, provided that the rules are relevant. We use the information obtained in tis way for the presentation of advertisements on Facebook (partner) pages or other websites. If you wish to object to the use of Facebook Pixel, you can set an opt-out cookie on Facebook or disable JavaScript in your browser. For additional information and configuration options for protecting your privacy within the scope of advertising activities, please refer to Facebook's privacy policy which can be found, among others, at
