@mentra/bluetooth-sdk@3.3.0
SDK for communicating with smart glasses
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package performs disclosed runtime telemetry, but its payloads include the host app’s package identifier and may include a glasses device ID. Under the review rules, telemetry carrying identifying details is suspicious even when disclosed and disableable.
Static reason
No blocking static signals were detected.
Trigger
Analytics runs during SDK use by default; the update check runs when the SDK starts, regardless of the analytics setting.
Impact
Mentra can associate SDK usage with an app package and install, and may receive a connected-glasses device ID; this identifying telemetry warrants a warning.
Mechanism
Native Android code posts usage events to PostHog and host metadata to the SDK update-check endpoint.
AI rationale
The package performs disclosed runtime telemetry, but its payloads include the host app’s package identifier and may include a glasses device ID. Under the review rules, telemetry carrying identifying details is suspicious even when disclosed and disableable.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The SDK sends runtime usage events to Mentra’s PostHog with a persistent install ID and the host app’s package identifier; connected-glasses device IDs may also be included.
- On SDK startup, an update check sends the install ID, app identifier, and app build details to core.mentraglass.com, even when analytics are disabled.
- The README discloses both telemetry paths and documents ways to disable analytics.
Evidence against
- The package is a Bluetooth SDK, and its native code and bundled libraries support that purpose.
- The update request is limited to SDK and host-app metadata; no credential or file-content collection was found.
