△ PHOSPHOR SWL SUITE — PRIVACY POLICY

Last updated: September 2026

SCOPE

This policy covers the Phosphor SWL Suite bundle as a whole. Each included app also publishes its own privacy policy, linked at the foot of this page, and those are authoritative for that app's specifics.

DATA COLLECTION

None of the apps in this bundle collect, store, or transmit personal data. No app requires an account, registration, or sign-in of any kind.

ANALYTICS AND TRACKING

No app in this bundle includes analytics frameworks, crash reporters, advertising SDKs, or third-party tracking of any kind.

MICROPHONE AND CAMERA ACCESS

PhosphorRTTY, PhosphorCW, PhosphorSSTV, and PhantomGram use your device's microphone to capture audio for real-time signal decoding. All audio processing occurs entirely on-device in real time. Audio is not recorded, stored, or transmitted. No audio data ever leaves your device.

PhantomGram also requests camera access if you choose to capture an image for transmission. Image data is processed locally and is not stored beyond the current session, apart from images you explicitly save to the log.

LOCATION

PhosphorHertz uses your device's location to determine your station position for propagation calculations, covering MUF estimation, solar zenith angle, sunrise and sunset times, and great-circle path geometry. This is processed entirely on-device and is never transmitted, stored, or shared.

NETWORK REQUESTS

PhosphorRTTY, PhosphorCW, PhosphorSSTV, PhosphorCalc, and PhantomGram make no network requests. They are entirely offline.

PhosphorHertz retrieves live space weather data from the NOAA Space Weather Prediction Center. PhosphorSWL downloads publicly available shortwave broadcast schedules from eibispace.de and the current planetary K-index from the same NOAA service. These requests are made directly from your device, carry no account, identifier, or personal information, and pass through no intermediary server operated by us.

LOCAL DATA STORAGE

Each app stores its own decoded output, cached public data, and user preferences locally on your device using standard iOS mechanisms. This data never leaves your device.

THIRD-PARTY SERVICES

No app in this bundle uses third-party SDKs or frameworks. All are built with Apple's native frameworks. The only external services contacted are the public data sources named above, and their use of any data is governed by their own policies.

CHILDREN'S PRIVACY

No app in this bundle collects data from anyone, including children.

PER-APP POLICIES

CHANGES TO THIS POLICY

If this policy changes, the updated version will be posted here with a revised date.
