Canary Mail collects some data but says none of it is linked to your identity, and none is used for tracking.
Did Canary Mail ask for something?
Pick the permission prompt you saw. We compare it with what Canary Mail's developer declared.
Location is not on Canary Mail's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
Canary Mail lists User Content on its label. Choose Limited Access and pick only the photos you want to share.
Contacts is not on Canary Mail's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
Canary Mail declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.
Health & Fitness is not on Canary Mail's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.
What Canary Mail collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| User ContentSensitiveNot linked to you | Messages, photos, videos, audio recordings, documents and support chats you create or upload. | Settings › Privacy & Security › Photos: choose Limited Access or None; review Microphone and Files access too. |
| Contact InfoNot linked to you | Your name, email address, phone number or postal address. | Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences. |
| Usage DataNot linked to you | What you tap, open and view inside the app, plus which ads you have seen. | There is no single iOS switch. Look for an analytics or personalised-ads toggle in the app's own settings. |
| DiagnosticsNot linked to you | Crash logs, launch times, hang rates and energy use. | Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate. |
What Canary Mail's label means for you
Canary Mail's label has 4 types under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.
Every type on Canary Mail's label is in the “not linked” section, so the developer says the data is stripped of anything that identifies you before it is used. That is typical of anonymous analytics and crash reporting. Not linked is still collected: the data leaves your phone.
The items that deserve the most attention are user content. This is the content you actually care about. Where it is stored, who can read it and how it is backed up matters more than any other line on the label.
Email apps see every message and contact. Third-party mail clients may route mail through their own servers to offer features like push or AI summaries. Check whether the client connects to your provider directly or stores your mail on its servers.
Among the 141 secure email apps in our snapshot with a label, 28% declare tracking, 60% collect data linked to you and 23% say they collect nothing. Canary Mail lists 4 data types, more than the average of 2.9 for this group.
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

Lock Canary Mail behind Face ID
- Find Canary Mail on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Canary Mail now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Canary Mail has a passcode of its own. It does not change what the app sends to its developer.

What the label cannot tell you
- A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Canary Mail sends.
- It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
- Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
- Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
- Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
