Short answer

Mostly a question of trust: StrengthLog collects data linked to you but declares no tracking. None of it falls in Apple's most sensitive categories (health, financial, location, contacts or your own content). In total the label lists 4 data types; 59% of health trackers we checked declare tracking.

Not on the label

Location is not on StrengthLog'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.

Not on the label

User Content is not on StrengthLog'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.

Not on the label

Contacts is not on StrengthLog'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.

Not declared on the label

StrengthLog declares no tracking, so a tracking prompt would contradict its label. Decline it, and consider reporting the mismatch to Apple.

Not on the label

Health & Fitness is not on StrengthLog'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.

Line by line

What StrengthLog collects, explained

Data typeWhat it coversWhere to limit it
Contact InfoLinked 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.
IdentifiersLinked to you An account ID, screen name, customer number or a device-level ID such as the advertising identifier. Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted.
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.

Reading the label

What StrengthLog's label means for you

StrengthLog's label has 3 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.

StrengthLog 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 — contact info, identifiers and diagnostics — is still tied to your identity, typically through an account, and is covered by the developer's privacy policy and retention rules.

None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.

Health trackers collect symptoms, vitals and habits. In the US, most consumer health apps are not covered by HIPAA, so the privacy policy is your main protection. Grant HealthKit categories one by one in the Health app, and avoid connecting categories the app does not need.

Among the 180 health trackers in our snapshot with a label, 59% declare tracking, 84% collect data linked to you and 3% say they collect nothing. StrengthLog lists 4 data types, fewer than the average of 5.1 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.

On your iPhone

Settings to check for StrengthLog

  1. 1

    Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. 2

    Health

    Health app › your profile picture › Apps › StrengthLog. Turn categories on one at a time; the app cannot tell which ones you declined.

  3. 3

    Sign-in

    When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.

  4. 4

    Lock the app

    On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.

  5. 5

    Notifications

    Settings › Notifications › StrengthLog › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

iOS 18 and later

Lock StrengthLog behind Face ID

  1. Find StrengthLog on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. StrengthLog now asks for authentication every time it opens.

The lock is an iPhone feature, so it works whether or not StrengthLog has a passcode of its own. It does not change what the app sends to its developer.

Read with care

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 StrengthLog 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.
