At a glance: How to mask app user IP addresses in AppsFlyer raw data reports and in postbacks sent to partners.
IP masking
When turning on IP masking:
- User IP addresses aren't listed in raw data reports nor are they provided via postbacks to partners
- IP address field is populated with the value 1.1.1.1
Note
- Installs that occurred before IP masking was turned on aren't masked
- AEM data sharing for Meta ads isn't supported for both server-to-server and SDK events when IP masking is turned on. This means data isn't shared with Meta ads.
Example
- The IP masking setting follows this path: Turned off, turned on, and then turned off.
- Three users install the app on different dates as shown in the app install table
- The IP masking and raw data report table below shows the status of the IP masking setting and related raw data on the relevant dates.
