# dns I switched from manually editing my local hosts file to using [Pi-hole](https://pi-hole.net/). Pi-hole is a [DNS sinkhole](https://en.wikipedia.org/wiki/DNS_sinkhole) that runs on local hardware (for example a Raspberry-Pi or an old laptop). The advantage is that it can block ads and tracking for all other devices in your local network. Exactly, that means smartphones too! [Pi-hole](https://pi-hole.net/) offers cool stats, a one click "block this domain" functionality and general peace of mind as it has a big list of denied trackers. Combined with a browser like [Vivaldi](https://vivaldi.com/) it makes the modern web less annoying. ## Why should I do this? I recommend reading ["The Age of Surveillance Capitalism: The Fight for a Human Future at the New Frontier of Power"](https://www.goodreads.com/book/show/26195941-the-age-of-surveillance-capitalism) by Soshana Zuboff. It's an accurate description of what is happening: we are tracked online and offline to be sold as "data" to create personalized advertisement to modify our behavior. I am not against online ads per se, but the privacy invasion is huge. I like my privacy. An easier-to-digest alternative is ["The Great Hack"](https://www.netflix.com/title/80117542) on Netflix about the scandal of Cambridge Analytica and Facebook. ## Alternatives Listing some privacy-preserving alternatives to commonly used services. **Search engine**: https://duckduckgo.com/ **Email provider**: https://mail.protonmail.com/ **Disposable email providers**: https://10minutemail.net/ - https://temp-mail.org/en/
