This policy describes how MIDIWorld (“the App”) handles information when you use it. MIDIWorld turns sensor and environmental signals on your device into MIDI data for music and experimentation.
MIDIWorld is provided by Los Palmos LLC, a Pennsylvania limited liability company (“Los Palmos,” “we,” “us”). For privacy questions, contact us at admin@lospalmos.org.
Most processing happens locally on your iPhone or iPad. That includes mapping motion, touch, light, proximity, device orientation, audio level/pitch-derived values (when you grant microphone access), and similar inputs into MIDI-style control values and recordings you create.
Recordings, presets, and exported files you generate are stored in your app’s sandbox or shared by you through the system share sheet. We do not operate a cloud account or sync service for your sessions as part of the App itself.
If you allow location access, the App uses your device’s location (precise or approximate, depending on the permission and the Precise Location setting you choose in iOS) to:
For these requests, the App sends the latitude and longitude reported by iOS to Open-Meteo, USGS, and Apple MapKit without rounding or otherwise reducing their precision. If you have allowed precise location, these providers receive your precise location. See “Internet and third-party services” below.
If you do not grant location permission, the App uses a default location in San Francisco, California for these features instead, and does not send your own location to these providers.
MIDIWorld does not sell your location.
Background location may be used only when you have granted the appropriate permission and the App needs it for features you enable; iOS controls when background updates are delivered.
If you grant access to Apple Health, the App may read the categories you authorize (for example heart rate, activity, or related metrics described in the permission prompt) to map values to MIDI. Health data is read through HealthKit on your device and is not transmitted to our servers by the App, because the App does not operate such servers for that purpose.
If you grant microphone access, the App analyzes input to derive control signals (such as level or pitch estimates) for MIDI. It is not intended to upload or store your raw audio on our servers; the App does not include that functionality.
Motion and fitness-related data (for example accelerometer, gyroscope, pedometer, activity classification) may be used on device when you use corresponding features. Bluetooth proximity and network quality metrics are used locally to drive MIDI where supported.
When you use features that depend on live data, the App makes network requests directly from your device to the third-party providers listed below. This is the complete list of outside services the App contacts. We do not operate servers that receive this data. As with any internet request, each provider also receives your device’s IP address and standard request information (such as the time of the request), and handles requests under its own terms and privacy policy, which are outside our control.
Only Open-Meteo, USGS, and Apple MapKit receive location information from the App. Requests to Yahoo Finance, CoinGecko, and Frankfurter do not include your location.
The only third-party code in the App is the open-source AudioKit audio packages, which process audio on your device and do not send data anywhere. The App contains no third-party analytics, advertising, or crash-reporting tools. If that ever changes, this policy will be updated.
Theme, MIDI routing preferences, and similar options may be stored using Apple’s standard on-device storage (for example UserDefaults) and remain on your device.
The App is not directed at children under 13 in a distinct way; parents and guardians should supervise use of device permissions and sharing of exported files.
We may update this policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the App after changes means you accept the updated policy.
