Sending data to the server by Yandex Browser

Data transfer is enabled by default for the following browser features:

• Crash reports. If Yandex Browser or its components close unexpectedly, crash reports are sent to the server.

  Disable sending crash reports

  Attention. We recommend keeping this setting enabled. Crash reports help developers fix bugs.

  1. Click   → Settings → System.
  2. At the bottom of the page, click Personal data settings.
  3. Disable the Send crash reports to Yandex option.

• Protection against malware and malicious sites. If the user visits a suspicious site, Yandex Browser sends the hash prefix of this page to the server.

  Technical details

  The Yandex condensed database of malware and phishing sites is downloaded to your computer. It contains the hash prefixes of addresses of dangerous pages. Before opening a page, Yandex Browser calculates the address hash and checks the hash prefix against the local database. If there is a match, Yandex Browser sends the server the prefix of the page and gets the full hashes of malicious pages that start with this prefix. If the list of pages contains the hash of the requested page, the page is blocked.

  When downloading a file, Yandex Browser checks it for malware. When checking the file, information about the file, the history of the tab the file was downloaded from, and other data is sent to the server.

  Disable protection against malware and malicious sites

  Attention. We recommend keeping this setting enabled. If Yandex Browser stops blocking pages on infected and phishing sites, malware may get into your computer.

  1. Click  → Settings.
  2. Go to Security.
  3. Disable security options.

• Navigation error help. If the user enters a nonexistent website address, Yandex Browser sends this address to the Yandex server. Yandex web service will help you find the website address or suggest viewing a saved copy of the website if the page was deleted.

  Disable navigation error help

  1. Click   → Settings → General settings.
  2. In the Search section, disable the Offer corrections for typos in site addresses option.

• Generating suggestions. When you enter a query or a website address in the SmartBox, it is sent to the default search engine and is used to create suggestions for addresses and queries.

  Disable suggestions

  1. Click   → Settings → General settings.
  2. In the Search section, disable the Show suggestions when entering addresses and queries option.

• Autofill for forms. When you enter information in a form (such as your name, address, email, or phone number), Yandex Browser remembers it so that later you save time and complete forms in just one click. This information is not sent to the server. However, if Yandex Browser asks the server for information about what the form fields mean, the form's address may be sent to the server.

  Turn off form autofill

  1. Click   → Settings → Tools.
  2. Disable the Suggest form autofill option.

If you activate these features, they will start sending data.

• Syncing. When syncing devices, Yandex Browser sends bookmarks, passwords, history, autofill data, extensions, and open tabs to the Yandex server. You can turn off syncing or adjust the list of data to sync at any time when using the browser.
• Sending statistics. If you enable sending statistics, depersonalized data about Yandex Browser usage will be sent to Yandex. This data will help identify problem areas in the Yandex Browser interface, kernel, and other components, along with problems in other Yandex servers.

The following features send data only while they are in use:

• Page language detection. To detect the language, Yandex Browser uses local tools alone or both local and server tools. The second method is more accurate. It requires part of the page text to be sent to the server. To use only local tools, go to Tools in settings and deselect the Send text snippets to Yandex to improve translation quality option.
• Page translator. If the page language is different from the browser interface language, the browser suggests page translation. If you agree, the text on the page is sent to the server, which returns it translated. You can disable translation on the Tools page in Settings.
• Word and phrase translator. Yandex Browser can also translate individual words and phrases on the page for you by sending them to the server. You can disable the translation of words and phrases on the Tools page in Settings.
• User location. Some websites request information about your location. You can view and edit the list of websites that you allow to track your location, or block location tracking on all websites.
