Frequently asked questions

We offer participation in the study to randomly selected people. For the purposes of the study, we build a research sample. The research sample, i.e. the panel, is a permanent group of people among whom we will continuously measure media use. We want the structure of this group to correspond to the structure of the entire country for which we are conducting the study.

Recruitment for the study takes place randomly through our internal recruitment campaigns such as surveys inviting people to participate in the study, where an invitation is randomly generated, or through external recruitment conducted by a recruitment company. This is the only way to proceed to the examination.

Currently, we conduct recruitment in two ways. We recruit directly, meaning a recruiter representing Gemius contacts a randomly selected candidate at their place of residence. After completing the recruitment questionnaire and signing the contract, the panelist immediately receives the research device.

It is also possible to join the study by filling out an online form. On selected websites, a random invitation to participate in the study may appear. Once the form is submitted, the data is sent to Gemius. People who express willingness to participate and match the sought demographic profile are invited to take part in the project. The participation agreement is sent via email. Once signed, a courier will deliver the phone to the address provided in the form.

Personal data is required to sign the project participation agreement. We are offering a smartphone which is of significant value, so we want to sign a contract with you that regulates the obligations of both parties.

You can resign from participating in the study at any time - please let us know by e-mail or telephone. A person who resigns from participating in the screening is obliged to return the smartphone to Gemius.

No. You must insert your own SIM card into your Gemius phone.

You only incur costs related to the current use of the phone (internet connection, charging the phone, etc.). The increase in transfer consumption due to participation in the study is unnoticeable - the data files that will be sent to the research company are very small.

Installing the research plugin is optional and free of charge. It is installed in the web browser if you also use a desktop or laptop. The plugin collects data about your website visits, which is sent to the Gemius data analysis center and, combined with socio-demographic data, provides statistical insight into internet user behavior. Information about data processing is provided during installation and in the Privacy Policy.

Installing the research plugin entitles you to participate in contests organized by Gemius. Each contest has its own terms and conditions, which will be made available to you for acceptance before participating.

You can uninstall the plugin at any time.

We verify online-recruited candidates within a week. After qualifying for the project, we send information about the next recruitment steps. If you haven’t received a message from us within a week of completing the form, please contact us.

Use your Gemius phone normally, just like you usually do.

No. Research software automatically collects and transmits data. This should be unnoticeable to you.

This must be your main phone that you use every day.

No. During the term of the contract, only the person who signed a contract with us to participate in the study can use the phone.

Yes. We want you to use your phone in a natural way.

Yes. However, it sometimes happens that application producers do not allow their use on phones with Gemius research software. This situation is rare, but if it happens to an application that is important to you, please contact us - we will try to help.

Yes. Your data is safe, we only collect information about the websites you visit and the start and end time of using individual applications.

According to the provisions of the contract - no. Research software works with a specific version of the operating system. We are constantly working on adapting the software to newer versions of the system. If you need to update the system, please contact us.

According to the provisions of the contract - no. If necessary, please contact us.

Warranty service for the phone is the responsibility of Gemius. In case of damage, please contact us.

In this case, please contact us.

Gemius services the research telephone at its own expense. In case of damage to the device, please contact us.

In this case, please contact us as soon as possible. We will provide the next steps.

Generally the contract's basic period is 2 years.

We use an electronic contract signing method. The contract will be emailed to you and can be opened on any device with a web browser. Signing is simple—just follow the SIGN arrow. After signing, both parties will receive a copy along with a verification report. This ensures content integrity. Signing the contract this way is safe, fast, and legally binding.

Yes - in such a case, please return the telephone number to the Gemius address along with your resignation from the contract (in writing or by e-mail).

After the contract ends, the phone may become your property.

After the contract ends, we remotely deactivate the research tracking tools installed on the phone. If you notice any activity from our apps, please contact us.

1. There may be situations when we ask you, for example, to restart your phone or manually update the application. You will then receive detailed instructions from us on how to do it.
2. If you change data such as name, address, telephone number or e-mail, please contact us. Therefore, for the quality of the study, it is important that the data we receive from you is up to date
3. If your phone breaks, please contact us. All phone repairs are the responsibility of Gemius.

1. We contact the panelist at the begining of the contract to verify user of the phone, during satisfaction surveys of participation in the project.
2. We may also contact you when we do not receive information about activity on your phone or when there are technical problems with the data we receive.
3. We periodically contact our panelists to update your demographic information (e.g. education, household size). This may be a telephone contact or an electronic form in the form of a link to a survey to be completed, sent by text message or e-mail.

The research software installed on the phone prepares reports (data packets) and sends them to Gemius.

We use 'Sound Matching' technology to recognize radio and TV stations. It works by comparing samples generated from signals received from TV stations with reference samples.

The Gemius software does not store audio files, and the original sound cannot be reconstructed from the samples. This method is widely used by research companies worldwide to measure media consumption, even via smartphones. It’s also used in some apps, such as music recognition tools.

Data is sent continuously whenever there is an internet connection (Wi-Fi or other).

The amount of data depends on how actively you use browsers and apps on your phone. Data is sent to Gemius continuously. If there is no internet connection, it is stored until the connection is restored, then the stored data is sent.

Yes. The security of your data is our priority. We operate in accordance with the principles of the international ICC/ESOMAR code, which proves that our projects are carried out in compliance with the highest ethical standards. More information can be found in the privacy policy.

As part of the project, we collect data about Internet activity - both on websites and in applications.

We also collect information about TV and radio channels. The Gemius software does not collect any audio files, and the original sound cannot be reproduced from the prepared samples

The data we collect is only used in aggregate reports. It is not possible to identify a specific person based on them. Each project participant has a specific socio-demographic profile (e.g. age, gender, education), and we use the measurement results in rankings based on these characteristics.

We do not collect data regarding the content of your communication and correspondence. Our research does not have access to text messages, phone numbers, photos, account numbers or passwords on your phone.
