**As soon as you install Siri, Apple also warned that part of the audio data collected by this virtual assistant will be sent to its servers.** The aforementioned data includes contacts, nicknames, your favorite playlists, device names, installed apps names, shortcuts installed for Siri… along with Dictation data. One point to note is that the virtual assistant will only send data to Apple after you call it with the “Hey Siri” command. Additionally, Apple will store all submitted data for 6 months – after which it will be classified and stored for an additional 2 years to further improve Siri and Dictation. **Temporary prevention** If you don’t want to uninstall Siri, you have a manual way to clear Siri and Dictation history – indirectly preventing data from being sent to Apple servers. First, open Settings / Settings > Siri & Search (Siri & Search) > Siri & Dictation history. You’ll see an option to Delete Siri & Dictation History, which will sever the link between the data collected by Siri and Dictation on your iPhone and Apple’s servers. You should also do this on other Apple devices you own and repeat every 6 months. **And radically** If you’re worried that some “Hey Siri”-like noise could get into your iPhone, the data is then sent to Apple and determined to part with the virtual assistant – here’s what things to do. To disable the “Hey Siri” voice command, go back to Settings > Siri & Search and turn off Listen for “Hey Siri,” there. Next you uncheck the options Press Side Button for Siri (Press the side button to turn on Siri), Allow Siri When Locked (Allow Siri when locked). With Dictation, you need to go to Settings > General/General > Keyboard/Keyboard and turn off the Enable Dictation/Enable Dictation option. If you’ve done all of the above, the good news is that Apple will also delete the Siri data that was previously stored on the server.
