Privacy Policy

Last Updated: April 23, 2026

This Privacy Policy describes how the CueSync mobile application ("App") collects, uses, and safeguards personal data. By installing or using the App, you agree to the terms of this Privacy Policy. If you do not agree, do not use the App.


1. Ownership and Scope

1.1 Ownership The App is owned and operated by Spiridonov Nikolai Aleksandrovich, IP. All rights not expressly granted to you are reserved by the owner.

1.2 Applicability This Privacy Policy applies solely to the CueSync App available on the iOS platform and does not extend to any third-party services or websites that are not under our direct control.


2. Information We Collect

2.1 No Required Personal Data We do not require you to provide personal information (e.g., name, email, address) to use the App. We do not ask you to create an account or register, and we do not knowingly collect any information that could directly identify you.

2.2 On-Device Speech Processing The App uses your device’s microphone to perform on-device speech recognition for the Speech Sync feature. All audio processing occurs entirely on your device. We do not transmit, store, or have access to any audio recordings or speech data. Your voice never leaves your device.

2.3 Scripts and Content All scripts and text content you create or import into the App are stored locally on your device using on-device storage. We do not have access to, collect, or transmit your scripts or any content you enter into the App.

2.4 Camera and Video Recordings If you enable the camera feature, all video recordings are saved locally on your device. We do not upload, transmit, or have access to any video content captured by the App. You retain full control over your recordings — you can save them to your Photo Library, share them, or delete them at your discretion.

2.5 Device and Usage Data Certain data may be collected automatically to improve functionality and user experience:

  • Device Information: Model, operating system version, unique device identifiers (including Device ID and, if authorized, IDFA).
  • App Usage: Version, build number, session timestamps, pages/screens viewed, performance metrics, crash reports, and diagnostic information.

This data is used solely for internal analytics, debugging, and performance optimization. We do not use it to personally identify you or to track you outside of the App.

2.6 In-App Purchases The App offers subscription-based Premium services. These are processed via Apple’s in-app purchase mechanism. We do not store or process payment card details. We may receive non-personal data (e.g., subscription status) to enable or disable premium features accordingly.


3. Microphone and Camera Access

3.1 Microphone Purpose The App requests microphone access solely for the Speech Sync feature, which uses on-device speech recognition to track your reading position and scroll your script accordingly.

3.2 Camera Purpose The App requests camera access to allow you to record yourself while reading from the teleprompter, as a fullscreen background or a picture-in-picture overlay.

3.3 No Recording or Transmission of Audio Audio captured by the microphone for Speech Sync is processed in real time on your device and is not recorded, stored, or transmitted to any server. Once processed, the audio data is immediately discarded.

3.4 Local Video Storage Video recordings created with the built-in camera feature are stored locally on your device only and are never uploaded or transmitted to any server by the App.

3.5 Optional Permissions Both microphone and camera access are optional. You can use the App’s Fixed Speed scroll mode without microphone permission, and you can use any scroll mode without camera permission. You can enable or revoke these permissions at any time in your device’s Settings.
