You can toggle your Data Privacy Controls at any time by pressing on the cogwheel next to your Discord username to open up User Settings. While there, then tap on Privacy & Safety.
Usage Statistics
Turning this off means we will no longer track how you use and/or navigate Discord outside of data needed to provide the service, meet our commitments to our users, and satisfy our legal requirements. This data includes, for example, the fact that you joined a server — we need to know that to provide you access to the server!
We use usage statistics to improve Discord and to make it more pleasant for you to use.
By disabling this setting, your account will be ineligible for feature experiments that are used in testing. Your information will also not be included in server-level experiments such as Server Insights. It will also prevent us from automatically improving your voice quality based on your usage.
Once turned off, any previously collected data will no longer be directly associated with your account — even if you turn this setting on in the future, your past usage statistics are not tied back in. We may continue to use previously collected data to help us understand and improve our products.
If you’d like to further assert your right to object to our processing of your data, email privacy@discord.com.
When you turn the flag off, the events are sent, but we tell our servers to not store these events. They're dropped immediately and are not stored or processed at all. The reason that we chose to do it this way is so that when you turn it off on your desktop app, it also turns off automatically on your phone - and vice-versa. This allows us to keep things the same across all of our apps and clients, across upgrades.
Personalization Data
Personalization data is used to make your specific Discord experience better for you. For example, we use this information to update and maintain the Active Now section of the Friends Tab and to power parts of Server Discovery.
Once turned off, any previously collected data will no longer be directly associated with your account — even if you turn it on in the future, it won't use any data from when it was turned on in the past. Previously collected data will not be used to personalize the product for you.
