“Private” gets used loosely. If you keep anything genuinely sensitive on your iPhone — documents, ID scans, personal photos — it is worth understanding where those files actually live and how to protect them.
Where your files actually live
Most saved files sit in one of three places: on your device, in a company's cloud (their servers), or in your own iCloud tied to your Apple account. These are very different. A file on a developer's server is only as private as that company's security and policies. A file in your own iCloud is scoped to your Apple account, like the rest of your iCloud data.
Lock the app, not just the file
Hiding individual items is fragile. A cleaner approach is to keep sensitive saves in a dedicated organiser and lock the whole app behind Face ID or a PIN. That way a handed-over or lost phone does not expose anything, and you do not have to remember which items you hid.
Lock your private files behind Face ID
EZ Save keeps links, photos and documents in one library, locked with Face ID or a PIN and stored in your own iCloud.

The strongest privacy comes from apps that simply do not hold your content. If there is no developer database storing your files, there is nothing to breach and nothing for the company to read. On iOS, apps can store your data in Apple's CloudKit private database — your own iCloud — so the developer never sees it.
A quick privacy checklist
- Keep sensitive documents in a dedicated, lockable app — not your general camera roll.
- Turn on Face ID / PIN locking for that app.
- Prefer apps that store data in your own iCloud rather than their servers.
- Check what an app actually uploads — good apps tell you plainly.
- Avoid apps that demand an account just to store your files.
Privacy is not about hiding — it is about control. When your files live in your account and your app is locked to you, you decide who sees what.
