can I delete Analytic data from iPhone?

Hello massoud.mg,

As mentioned in the last message, you're not able to delete any analytic data. If you'd like to submit feedback about this, you can do so using this link: Feedback - iPhone

We'd also like to provide two other links that'll help with managing the built-in storage of your iPhone, as well as your iCloud storage:

1. How to check the storage on your iPhone, iPad, and iPod touch
2. Manage your iCloud storage

Cheers.

Hey there massoud.mg,

We'd like to answer your question about Analytic Data as best we can.

None of the Analytics data identifies you personally. While you're not able to delete any analytic data, you are able to turn it off within Settings > Privacy > Analytics & Improvements > Analytics Data.

This link goes into more detail about Device Analytics & Privacy.

Take care!
