Knowtex collects 2 data types tied to your identity but declares no tracking.
Did Knowtex ask for something?
Pick the permission prompt you saw. We compare it with what Knowtex's developer declared.
Location is not on Knowtex'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.
Knowtex lists User Content on its label, linked to you. Choose Limited Access and pick only the photos you want to share.
Contacts is not on Knowtex'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.
Knowtex declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.
Knowtex lists Health & Fitness on its label. Approve Health categories one at a time in the Health app.
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 Knowtex's label means for you
Knowtex's label has 2 types under “Data Linked to You”, 2 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.
Knowtex declares no tracking, which means the developer says it does not combine your data with other companies' data for advertising or sell it to data brokers. The data linked to you — user content and contact info — is still tied to your identity, typically through an account, and is covered by the developer's privacy policy and retention rules.
The items that deserve the most attention are health and fitness and user content. Health data is among the most sensitive data an app can hold, and US health-privacy law (HIPAA) does not cover most consumer apps.
Medical-record apps hold diagnoses, prescriptions and insurance details. Patient portals from your provider are bound by health-privacy rules in a way most standalone apps are not. Confirm the app is published by your hospital, insurer or a well-known records service, and turn on its login lock.
Among the 191 medical records apps in our snapshot with a label, 8% declare tracking, 71% collect data linked to you and 20% say they collect nothing. Knowtex lists 3 data types, fewer than the average of 4.8 for this group.
Health and fitness apps can read Apple Health data only for categories you approve, one by one. What they collect themselves is shown on the label.

There is no “Data Used to Track You” section on Knowtex's label.
Lock Knowtex behind Face ID
- Find Knowtex 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. Knowtex now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Knowtex 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 Knowtex 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.
The question to ask Knowtex's developer: Is this app run by my healthcare provider, or a third party?
