Where do my voice notes go — does the app keep my audio?

For most voice AI apps, the answer chain looks like this: your audio is recorded on the phone, uploaded to the company’s servers (or their AI provider’s), and transcribed and summarized there. What happens after that depends on the policy: deleted, retained for a window, or kept until you delete your account. The privacy page will say “encrypted in transit” (true, and beside the point) and “we delete recordings after processing,” which is a sentence that only needs writing because they receive your recordings.

Deletion policies are admissions of collection. That’s the fastest way to read any voice app’s privacy page. Weighing a specific cloud app against an on-device one? Here’s what “private” actually changes when you switch.

Xtraktr’s answer is shorter because there’s less pipeline to describe. Your speech is transcribed by the iPhone’s own neural engine. The AI that asks you questions runs on the phone’s chip, and the drafts are assembled on the phone as well. We don’t have a deletion policy for your audio because we never receive it. There is no server on our side in the loop at all. You can verify this yourself in ten seconds: airplane mode on, everything still works.

The complete picture, including the part a skeptic should ask about: your saved notes sync between your devices through your own private iCloud — Apple’s infrastructure, your Apple ID, the same protected place your photos and messages live. Not our servers, and not readable by us. If you want the full argument for why this architecture beats any policy, that’s here.

Why it’s worth caring even if you have “nothing to hide”: voice notes are unfiltered by nature. The half-formed take on a client, the competitive hunch, the idea that might embarrass you — the material most worth thinking through out loud is precisely what you’d never type into a cloud tool.
