Data we access
srad requests access to the following device sensors and data sources solely to generate real-time visual art:
| Data source | How it's used |
|---|---|
| Heart Rate (Apple Watch) | Drives the pulse rhythm of the sphere |
| Step Count | Generates footstep ripples and orbit density |
| Accelerometer | Deforms the sphere shape based on gravity and movement |
| Gyroscope | Adds rotation and vortex effects to the sphere |
| Magnetometer | Shifts color hue based on the ambient magnetic field |
| Barometer | Adjusts the corona ring thickness |
| Location (When In Use) | Uses altitude and movement speed for visual effects only |
| Microphone | Reads ambient audio levels to generate surface spikes |
None of this data is recorded, stored, uploaded, or transmitted. It is read in real time, used to compute visual parameters, and immediately discarded.
What we do not do
- Collect personal information (name, email, age, or any identifier)
- Create or require user accounts
- Track you across apps or websites
- Sell, rent, or share any data with third parties
- Upload sensor data to any server
- Use data for advertising or analytics
Health data
srad reads heart rate and step count from Apple HealthKit solely to drive visual animations. We do not write any data back to HealthKit. We do not use health data for any purpose other than generating on-screen visuals.
Location data
Location access is used only to read altitude and GPS speed as inputs for the sphere's visual behavior. Your precise location is never stored, logged, or transmitted.
Microphone
The microphone is used only to measure ambient sound levels (volume) in real time. srad does not record audio, does not store audio, and does not transmit audio.
Children's privacy
srad does not knowingly collect information from children under 13. The app has no account system and collects no personal information from any user, regardless of age.
Changes to this policy
If we update this policy, we will post the updated version at this URL with a new "Last updated" date. Continued use of the app after changes constitutes acceptance of the updated policy.
