Privacy Controls

Yandex employs the most advanced security infrastructures and systems to ensure protection of personal information. We also entitle our users to manage their personal data and decide what data Yandex can keep about them.

Advanced data management tool

In June 2021, Yandex introduced an advanced data management tool that users can now access in their Yandex ID accounts. The tool allows to get a full copy of personal information collected by 70+ Yandex services, as well as to request its erasure. A similar tool is available to Yandex’s business partners, who can now request and delete archived data about their business accounts.

Your Tracking Protection

Third-party tracker blocking feature in Yandex Browser that enables users to access a list of all third-party trackers and choose which of them to allow or block.

Yandex password manager

An automated generation of strong, unique passwords and built-in password storage for secure yet seamless authorization.

Protection from scammers

A set of features that remove fraudulent weblinks from search index to protect banking details and transactions. Yandex Browser also displays website reviews to warn about risks.

Yandex ID protection

A technology that determines whether login credentials have been exposed to immediately suggest password resetting.

Bug Bounty Programm

Is there something our data security specialists possibly overlooked? We encourage programmers from outside of Yandex to help us safeguard our products and services by participating in a Bug Bounty contest for identifying vulnerabilities. Contestants who succeed in reporting a vulnerability get a cash prize and are also features in the Hall of Fame on the contest’s official webpage. There are three streams within the Bug Bounty program, each with its own rules and regulations.

About Cybersecurity System

At Yandex, everybody is responsible for keeping users’ data safe. While there is a dedicated Information Security Department headed by Chief Information Security Officer and an appointed Chief Privacy Officer who are in charge of in-depth oversight and reporting to the Board of Directors, all our employees regularly get trained on information security, personal data protection and are expected to follow strict security guidelines.
Cybersecurity risk monitoring is a continuous process that is accompanied by proactive measures to detect vulnerabilities, such as sensitivity testing, as well as clear protocols on how to act in case an incident has occurred. While we have been working hard over years to build secure, reliable systems that make such incidents highly unlikely, there is always a negligible chance we want to be vigilant about. We believe honest communication is the key to minimizing damage and are therefore committed to informing our users immediately if their data has been compromised.
  • We empower users to manage their data.
  • We only use our users’ data to create new services for them and improve those that already exist.
  • We never sell any user data to anyone.
  • We only process personal data that for a specific purpose only.
  • We only keep personal data for as long as it is necessary to fulfil the purpose for which it was collected or to comply with legal and regulatory requirements.
  • If we are required to disclose our user information at the request of a law enforcement agency, we do so in strict accordance with the law and only to the minimum extent necessary. We regularly report on the number of requests where some information was disclosed in our Transparency Report.
  • We commit to acting in strict compliance with applicable data protection laws.
