  1. ↑ Must be an Apple (iPod, iPad, &c.) owner to obtain an account, but works on Windows, as well.
  2. ↑ Yandex mail accounts can be created anonymously. However after approximately 2 months of usage all of a sudden on login Yandex says that your account seems to be hacked (which is not true), and in order to improve security you are not permitted to log in unless you provide a phone number. Since the user after 2 months most probably has important unread emails on the account, he renounces his privacy and enters his phone number.
  3. ↑ This information can be verified by anyone with access to internet. Servers location play role in a investigation and serves thereof for legal defense
  4. ↑ Statement cannot be verified to be actual true as the information is handled by servers not accessed by the public
  5. ↑ For services hosted by companies that also own web search engines: The results of ads are arranged for the user in accordance to his/her interests as determined from previous search queries or other information available to the search engine.
  6. ↑ Tracking the user is not necessarily bad faith behaviour – it has to be conducted in order to provide personalized search results.
  7. ↑ Must be an Apple (iPod, iPad, &c.) owner to obtain an account, but works on Windows, as well.
