This app did not meet two or more trust checks, has a critical issue in one, or has a red flag.
- What it means for you
- The app may include code to pass standard usage and device data to the app developer and integrated services. The breakdown below lists the data types and third parties involved.
- Main concern

Trust checks
Secure by Design
One criterion not metSecurity gaps detected
Why this result
This check looks for security issues at high severity or above in the code of this build, and at least one was recorded. Issues of this kind include a credential or token another app on the device can reach, sensitive data stored without protection, and network paths that expose information in transit.
Data Minimization
StrongTracking done right
Why this result
The check looks at analytics and attribution code for companies other than the developer: the data it reads, the companies named in code as recipients, and whether a consent step runs before that code. In this build, either no such code was recorded, or a consent step runs before it and the app's own disclosures describe the collection.
The app has consent tools in place, including a built-in privacy consent screen and a prompt asking for permission before personalizing ads. However, two separate consent systems are running at the same time and they write to the same storage location — whichever one runs last overwrites the other's record. This means the consent value that the code makes available to the advertising SDKs may not match what you chose. There are also signals of a working consent flow alongside signals that it may misfire, making it impossible to give a clean pass or fail. (Reviewed: every finding cited here was graded low-severity, so the confident wording above is not backed by a real problem and this check passes.)
Manifest Mismatch
One criterion not metDisclosure incomplete or contradicted
Why this result
The check compares the app's privacy disclosures against what the code does, and at least one claim did not match in this build. Mismatches of this kind include a data category collected but not disclosed, a recipient the disclosure omits, and an identifier attached to data the disclosure describes as anonymous.
User Control
StrongNo lock-in
Why this result
The check looks for a way to export the data an account has accumulated and a way to delete the account itself. In this build, either both were found, or the app has no account of its own and keeps its data on the device. For an app without an account, the developer has no server-side copy to export or delete, and deleting the app removes the data in its own storage.
Truly Local
StrongStays on the device
Why this result
This app presents itself as working offline or on the device alone. The check looks for any code written to send personal data to a server, including analytics, crash reporting and advertising code. None was recorded in this build.
Your snoring recordings and sleep history are stored on your device, which is positive. However, the app communicates with more than 30 analytics and advertising services, and one of those destinations — a telemetry address — could not be identified at all and does not appear in the privacy policy. It is unclear whether the events the app includes code to send to analytics platforms contain health-relevant details such as when you fell asleep, how long you slept, or your sleep quality scores. (Reviewed: every finding cited here was graded low-severity, so the confident wording above is not backed by a real problem and this check passes.)
Strengths
- Keychain items use device-only protection, preventing sleep schedule data from migrating to iCloud or other devices
- Facebook automatic event logging is disabled, limiting unsanctioned behavioral data collection
- The build names EU-based Amplitude endpoints as the destination of European users' analytics data
- Event analytics self-hosted via Snowplow under the developer's own infrastructure rather than a third party
- TikTok tracking is currently fully disabled despite the SDK being bundled
- Payment processing uses Stripe with local AES encryption of payment data
