What "pseudonymised data" means for your survey answers

When you take paid surveys, your answers are separated from your identity using a system called pseudonymization. Learn how this protects your privacy and keeps your personal data secure.

Key points

  • Personal data includes direct identifiers like your name and email address.
  • Pseudonymized data replaces your personal details with a random reference code.
  • Anonymized data permanently breaks the link between your identity and your answers.
  • Privacy laws give you the right to control your personal data and request its deletion.

Three ways your survey data is handled

When you join a market research panel, you share details about your life and opinions. You might wonder who exactly sees your name next to your answers. We use specific privacy terms to explain how this works behind the scenes.

The three main terms you will hear are personal data, pseudonymized data and anonymized data. These are legal and technical words used to describe how closely a piece of information is linked to your actual identity. They explain how companies keep your identity safe while still gathering useful research.

Understanding these terms helps you know what happens to your survey answers. It also helps you make informed choices about your privacy when you take part in paid online surveys or focus groups. You can learn more about this in our guide on how anonymous are surveys, really?.

Personal data and your direct identity

Personal data is any information that directly identifies you as an individual. This includes your full name, your email address, your phone number and your home address. It is the information you type in when you first create a panel account.

If you join a video interview, your face and your voice are also personal data. Your IP address, which is the unique number assigned to your internet connection, falls into this category too. These details point directly to you as a specific person.

At Reward Hours, we keep your personal data strictly separate from the survey answers you send to clients. We need your email to send you invitations and rewards, but the researcher buying the survey results does not need to know your name.

We store this direct information securely. We only use it to manage your account, verify you are a real person, and send your rewards. For more details on this process, you can read about how online survey panels work, and where your answers go.

Pseudonymized data replaces your name with a code

Pseudonymized data is information where your direct identifiers have been swapped out for a fake name or a reference code. The word comes from the concept of a pseudonym, meaning a false name. In market research, this is usually a long string of numbers and letters.

When you click a link to start a survey, we do not send your email address to the survey system. Instead, we generate a random ID number for that specific session. The researcher sees that a participant with a specific code selected a certain multiple choice answer, but they have no idea who that participant actually is.

This system is highly useful for managing market research safely. If a survey breaks or you experience a technical issue, the researcher can report that a specific code had a problem. We then look up that code in our secure system, match it back to your account, and fix the issue or credit you appropriately.

The main difference. With pseudonymized data, the link between your answers and your identity still exists, but it is locked away securely. Only the panel company holds the key to connect the two.

Anonymized data takes your privacy one step further. Data is fully anonymized when it is impossible to trace it back to you, even if someone had all the keys and codes in the world. The connection to your identity is permanently destroyed.

Once a research project finishes, researchers often combine your answers with thousands of others. They create summary reports that show general trends, like stating that half of the respondents prefer a certain brand of coffee. At this stage, the individual reference codes are deleted or completely detached from the answers.

Because anonymized data cannot be linked to a person, privacy laws treat it differently. It is no longer considered personal information under most regulations. Companies can keep these aggregate statistics for years to track long-term trends safely. This allows brands to see how consumer preferences change over time without storing anyone's personal details.

Safeguards to keep your information secure

Market research companies must follow strict rules to ensure pseudonymized data stays protected. We do not just hide your name and hope for the best. We actively build walls between your identity and your survey responses.

These safeguards are built into our technology and our daily business practices. Here are the main ways we protect your information:

  • We limit employee access, meaning only technical staff who need to manage rewards or fix accounts can see your real name.
  • We use secure encryption to scramble your personal details when they are stored on our servers.
  • We sign strict legal agreements with our clients, forbidding them from trying to guess your identity from your survey answers.
  • We ask you to avoid typing your name or contact details into open text boxes during surveys.

If a project requires sharing your actual contact details, like mailing a physical product to your house for a test, we ask for your clear permission first. You always have the choice to say no and skip that specific study. We never pass on your personal details without asking you directly.

Your privacy rights and taking control

Because pseudonymized data can still technically be linked back to you, privacy laws give you control over it. Depending on where you live, laws like the General Data Protection Regulation in Europe or privacy acts in California give you specific rights. You can explore this further in our summary of your GDPR rights as a survey panel member.

You have the right to ask what data a company holds about you. You also have the right to ask them to delete it. If you close your Reward Hours account, we delete your personal information and break the link to your pseudonymized survey answers.

We recommend reading the privacy policy of any survey panel you join. This document will explain exactly how they use codes to protect your identity. If you have specific legal questions about your local privacy laws, we suggest checking official government websites or consulting a qualified legal adviser.

Market research relies on honest opinions, and people are only honest when they feel safe. Understanding how your data is handled means you can share your thoughts with confidence. If you are ready to share your opinions safely, you can create a free account today.

Common questions

Does a survey client know my name?

No, survey clients do not see your name or email address when you take a standard survey. They only see a random reference code and the answers you provide. If a specific study needs your name, we will always ask for your explicit permission first.

Why do researchers need to use pseudonymized data?

Researchers use it to keep your identity safe while still allowing us to fix technical problems. If a survey stops working, the pseudonymized code allows us to figure out which account was affected so we can help you.

Can I request my data to be deleted?

Yes, you can ask to delete your account and personal data at any time. Once your account is closed, we remove your personal details and your past survey answers become permanently anonymized.
