Consumer Health Data Privacy Notice

Version 1.0.8 · Effective September 22, 2026

BTech LLC operates BiaVis. This notice supplements the Privacy Policy for information that may reveal or be used to infer an individual’s health, fitness, movement, or physical activity. Contact privacy@biavis.app.

Health data BiaVis processes

BiaVis can process workout type, repetitions, distance, duration, speed, pace, elevation, heart rate, active energy, cycling cadence, cycling power, and cycling speed. It can also process precise location and motion evidence used to verify a workout. Camera video stays on-device; derived body-joint coordinates may be uploaded for verification.

Sources and purposes

The information comes from you, iPhone and Apple Watch sensors, standards-based Bluetooth wearables and fitness sensors you explicitly connect, Apple Health when you grant permission, and BiaVis verification results. We use it to show workout analytics, save workouts and routes to Apple Health, verify performance, detect vehicle travel or implausible evidence, calculate standings and BiaVis Points, prevent fraud, fulfill your export/deletion requests, and keep the service secure.

Sharing

We share health-related information only with processors needed to provide the service, when you share an eligible run with friends or a Club, when required by law, or to protect a person or the service. BiaVis does not sell consumer health data, use it for targeted advertising, or use HealthKit data for marketing. Full routes stay private. Shared runs include a simplified map by default, with the first and last 200 meters hidden. You can turn off map sharing per run; offline changes take effect when they reach the server.

Apple Health boundary

Raw HealthKit samples remain on your iPhone and Apple Watch. BiaVis queries only permitted sample types within the exact workout interval and displays heart rate, cadence, power, or speed only when genuine samples exist. Apple’s Health settings control permission. Deleting BiaVis does not delete workouts already written to Apple Health; those are controlled in Apple Health.

Raw samples received directly from a connected Bluetooth sensor also remain on the iPhone and are never used as server verification evidence in this release. Live sensor speed is informational. GPS from the device that recorded the run — your iPhone, or your Apple Watch for a run recorded without the iPhone — is authoritative for verified movement. Live heart rate from Apple Watch during an iPhone run is handled like a connected sensor and never used as verification evidence. BiaVis stores at most one sample per capability per second in a protected gzip sidecar, applies per-activity record and byte ceilings, and limits completed raw sensor sidecars to 128 MiB across the device. Workout summaries remain after an older raw sidecar is evicted. Retained sensor sidecars are included only when the user deliberately prepares Download My Data on that iPhone.

Product-interest analytics do not contain health values, workout results, routes, camera joints, raw sensor samples, or any other consumer health data. BiaVis does not use a person’s health information to decide which subscription or marketing message to show.

Retention and deletion

GPS verification evidence is retained for 30 days when accepted and 90 days when review or suspicious; device-only practice traces are retained up to seven days. Verified competitive facts may remain pseudonymous after account deletion. Use Account & Safety to delete local workout history or the account, or email privacy@biavis.app to exercise applicable health-data rights.

Appeals and complaints

If we deny a rights request, you may reply to request an appeal. You may also contact the regulator or attorney general available under local law. We will not discriminate against you for exercising a privacy right.
