Every time you search on Google a request is made to <a href="https://keywordkeg.com/service/1/getKeywordData.php" rel="nofollow">https://keywordkeg.com/service/1/getKeywordData.php</a> to grab pricing/volume data. This means keywordkeg is aware of all your google searches. A privacy-aware solution could have been to make direct requests to Google API without proxying via keywordkeg middleware.
