The company spokesperson has explained the process by saying the following:
“Once the voice recording is six months old, Apple “disassociates” your user number from the clip, deleting the number from the voice file. But it keeps these disassociated files for up to 18 more months for testing and product improvement purposes.”
However, those who feel uncomfortable with this can turn Siri off, and any identifiers, including the data itself, is deleted. Despite the fact that the fact that Siri data is kept for two years, with protections in place, it should still be kept in mind that Siri and Apple are not unique in keeping your data. Anyway, it’s up to you to decide to trust your data to Apple or not, with a simple solution of turning your voice assistant off always available on your fingertips.
