Sponsored messages on Telegram are based solely on the topic of the public channels in which they are shown. This means that no user data is mined or analyzed to display ads, and every user viewing a channel on Telegram sees the same sponsored messages.\n\nUnlike other apps, Telegram doesn't track whether you tapped on a sponsored message and doesn't profile you based on your activity. We also prevent external links in sponsored messages to ensure that third parties can’t spy on our users. We believe that everyone has the right to privacy, and technological platforms should respect that.\n\nTelegram offers a free and unlimited service to hundreds of millions of users, which involves significant server and traffic costs. In order to remain independent and stay true to its values, Telegram developed a paid tool to promote messages with user privacy in mind. We welcome responsible advertisers at:";
