Data security

Yandex cares about the security of your data and results of data labeling. This section describes the key principles of working with data in Toloka.

We also advise that you read our recommendations for data protection in Toloka.

Key principles

  • The rights to the results with labeled data belong to the requester, and no one else.
  • Yandex treats the data that the requester sends to Toloka as strictly confidential. Support staff have access to this data. The list of employees granted this access is regularly reviewed and their activities are monitored by our team.
    Note. If necessary, the requester may grant access to their account to other users, for example, to their employees.
  • Performers must treat the requester's data as confidential: this is stipulated in the User Agreement. We make sure that no fraudulent performers get access to Toloka: cheaters get a warning or ban.
  • We only store the values of input data you upload to Toloka. However, we don't download the content from links in advance and we don't save this data on our side after the tasks are displayed.

Personal data

By transmitting data to Toloka, you automatically agree to this data being processed by third parties, namely, performers in Toloka.

To avoid transmitting personal data, you can anonymize the data yourself. For example, you can cover up people's faces in photos and change the pitch of the voice in speech recordings.

For tasks that use recognition of passports or questionnaires with personal information, you can cut out the fields with data and use separate tasks for them. For example, you can send the last name, first name, and patronymic separately for recognition.


I am the account owner. I want to assign ownership to another account so that another user can connect their Yandex.Disk and manage finances independently.

The account is created for the email address entered during registration. You can't link this account to another account. The requester can't connect the Yandex.Disk of another account to the active requester account either.

To manage your account balance and interact with external services, be sure to log in with the username and password specified during registration. If you can't share this data, the other user needs to create their own account.

How do I switch my account from "Requester" to "Performer"?

You can't change your account type from "Requester" to "Performer".

If you want to complete tasks, you need to register in Toloka once again, with a different username, but as a performer.

To create a performer account:
  1. Log out of your requester account.
  2. Go to the Toloka home page.
  3. Click Join.
  4. Follow the system instructions.
Note. You can use the same phone number to create a new account. For a step-by-step description of the registration process, see Registration and login.
The phone number belongs to another user

If you see this warning, make sure you entered the phone number correctly.

Please note that you can only have one requester account per phone number (see the User Agreement).

If Yandex.Passport linked to the wrong number, change it. For more information about linking a phone number, see Yandex.Passport help.

If you don't remember your credentials in Toloka, use Restore access.

If you deleted your account in Toloka, create a new Yandex account and register in Toloka.

How do I change the phone number in my account?

To change your phone number, go to Yandex.Passport and change your main number.

Note. If you don't have access to the old number, it takes a month to replace it. For more information about changing the phone number, see Help for Yandex.Passport.
