At Vodafone, we have a specialised team that monitors regularly the processing of your personal data, removes inconsistencies and proposes improvements with the aim of protecting your personal data to the maximum extent possible. Vodafone does its utmost to protect your personal data and does so in compliance with the law. It pays the same attention to the security of operating and location data and the confidentiality of your communication within the services that Vodafone provides.

Similarly, in those cases where your personal data is processed by one of our processors, we ensure that their security rules and procedures for processing personal data are appropriate, in particular that they contain so-called Minimum Safety Requirements. These companies may never process your personal data for other than contractually defined purposes. After our cooperation ends, the data is always returned to Vodafone or destroyed.

Vodafone provides mobile services in line with international standards for GSM services; measures related to possible monitoring in the GSM network are thus equivalent to what other mobile networks in the Czech Republic and the world provide. Under international standards, the GSM network is not intended for the transfer of classified information: it is intended, under EU security specifications, for the transfer of non-classified information with short-term validity. This can be interpreted to mean that no secret conversations should take place within the GSM network. This does not mean the Vodafone network transmits communication that is not secured and encrypted: the standard A5/1 encryption algorithm is used for the transmission of communication between the mobile device and the network.

If, in exceptional cases, a specific risk of breach of security occurs in relation to the protection of your privacy and such risk exceeds the adopted measures, we will inform you about all options for remedying the situation.

Securing your personal data

Considering the condition of technology devices, costs on execution, nature, extent, context and purpose of your personal data processing, as well as the potential and serious risks to your rights and freedoms, we apply the appropriate technical and organizational measures in order to ensure safety of your personal data that correspond to the risk. These measures help us to ensure the continued confidentiality, integrity, availability and resilience of the systems and services when processing your personal data. Vodafone has set up processes for regular testing, assessment and evaluation of the effectiveness of established technical and organizational measures to ensure safety of the processing.

To ensure the maximum safety of your personal data, we use the following security methods:

  • Aggregation - Aggregation is where detailed sensitive information is replaced by less detailed information.
  • Anonymization - Anonymisation refers to the activity of removing or obscuring fields in a data set, where such fields either directly identify an individual to which the data pertains, or could be easily used to identify that individual given other generally-available data.
  • Data masking (partial or total) - Masking means replacing sensitive data values by fixed or random data that is completely unrelated to the input.
  • Data masking (redaction) - Redaction means completely removing (deleting or blacking out) sensitive data.
  • De-Identification – Generic term for any method used to remove, reduce or obscure sensitive data - either anonymisation or pseudonymisation.
  • Encryption (deterministic, format preserving, keyed hashing, randomised) - The sensitive input value is encrypted by different ways.
  • Pseudonymisation - Pseudonymisation refers to the activity of replacing identifying fields by a made up label or handle typically something created specifically for this purpose. A major advantage of pseudonymisation over anonymisation is that it may allow data records generated for the same individual to be linked together via the same pseudonym thus enriching the ability to analyse the data, track trends over time etc.
  • Tokenisation – Tokenisation is when each output of an information de-identification activity transform is stored in a token store along with the input value that generated it.

Security of your data outside our control

We cannot take responsibility for any unauthorised access or loss of personal data outside our control.

We never request your secured personal or accounting data through communication means. It is your responsibility to keep your personal and accounting information safe and not share it with others.

Our website may contain links to third-party websites. We, however, bear no liability for the security and content of these third-party websites. Before using these websites or disclosing your personal data to these websites, we ask you to become acquainted with the respective company’s personal data protection principles and cookie file rules and principles.

The above also applies to all third-party websites or to content that you connect to through our products and services.

You can disclose your data in certain ways, for example through social network plugins (other than those offered by Google, Facebook, Twitter and Pinterest) or through third party services that allow publication or disclosure of assessments or other information. Other third parties are then able to use this information.

Social network plugins and social applications are operated by the social networks themselves and are subject to their own conditions for using and protecting personal data and to their own rules for cookie files. We therefore recommend reviewing these conditions and rules.

Message monitoring and recording

Based on the Act on Electronic Communications, a person operating a public communication network and/or a provider of publicly accessible electronic communication services is obliged to set up and secure an interface within its network for connecting end telecommunications devices for monitoring and recording messages.

Vodafone, as a mobile operator, receives monitoring requests from pre-defined entities based on formalised, approved and regularly revised procedures and does not have the right to assess the legitimacy of the monitoring in those cases where all formal requirements stipulated by legal regulations are fulfilled by the public authorities.

Message monitoring and recording is carried out by the respective public authority, and the operator does not have access to the content obtained directly by such authority.

Data Retention – the statutory obligation to process data for the purpose of preventing, seeking and detecting crime and prosecuting criminal offences

In addition to message monitoring and recording, the law provides an exhaustive list of the bodies authorised to request information about executed calls. Our company is obliged to collect and store for a period of six months all operating and location data created or processed in connection with the operation of public communication network and in connection with providing publicly available services.

We also have the obligation to provide information from the database of users of publicly available telephone services to the body authorised to request such information according to a special legal regulation.


To access their customer accounts, customers enter their respective passwords. To ensure that the customer account is as secure as possible, a password that does not contains several of the same numbers or a row of numbers should be chosen.

Neither Vodafone operators or salespersons have access to your whole password. For verification, they may only ask you for two system-determined numbers. They cannot influence the choice of these numbers. To protect your password, we recommend only disclosing these two numbers.

The customer password needs to be protected and must not be disclosed to third parties. This way you will ensure that no one gains access to your account. Protect your password, because anyone who uses your password will be considered someone authorised to act on your behalf.

Differentiation of password levels

Administrator password

Administrator password – applies to the whole customer account – it can be used to log in under any telephone number on a given account. It provides full control over the entire account and all its telephone numbers.

User password

User password – is mandatory for each telephone number and allows only basic changes to your customer account to be made. It is used in particular to access information about a telephone number and display the Smart Overview (Chytrý přehled), i.e., your current expenditure.

Payer password

Payer password – is voluntary and provides full control over the numbers grouped under one invoice number.
