GR Synth Privacy Policy

GR Synth is an iPhone synthesizer created by Endless Vocals. The GR Synth iPhone app does not collect, transmit, sell, or share personal data.

Data collection and tracking

• No account, login, or profile
• No advertising, analytics, or tracking
• No location, contacts, photos, microphone recordings, health data, or payment details
• No preset uploads, public submissions, or server synchronization
• No third-party SDKs or remote database connection

Presets and app storage

GR Synth includes 21 read-only presets bundled inside the app. They do not require a network connection. Personal presets that you create are stored only on your iPhone using the app's local storage and are not available to Endless Vocals or other users.

You can delete a personal preset inside the app. Removing the app from your iPhone also removes its locally stored presets, subject to your own device backup settings.

Audio and WAV exports

Synthesis and WAV rendering happen on your device. GR Synth creates an audio file only when you request an export. The file leaves the app only when you choose a destination through Apple's share sheet, such as Files or AirDrop. Endless Vocals does not receive or retain exported audio.

MIDI and audio connections

Optional Core MIDI and USB audio connections are processed by iOS and the devices or apps you choose to connect. GR Synth does not send MIDI or audio data to Endless Vocals.

Apple services

Apple may process App Store downloads, purchases, diagnostics, or information you choose to share with Apple under Apple's Privacy Policy. Endless Vocals does not receive your full payment details and does not add third-party analytics to GR Synth.

Website scope

This policy applies to the native GR Synth iPhone app. The separate browser-based synthesizer on radwall.com is a website service and is not included in the iPhone app binary.

Children's privacy

GR Synth does not knowingly collect personal information from children or any other users.

Changes

We may update this policy when the app or its services change. The current version will remain available at this URL with its effective date.
