VoxSync Privacy Policy

Last updated: October 19, 2026

This policy describes how VoxSync collects, uses, and discloses information when you use the app, including information processed by its advertising, analytics, authentication, cloud, AI, and support services. Contact the VoxSync support team at atenterprise.development@gmail.com about this policy or your data.

1. Information processed by VoxSync

Account information

When you choose Google Sign-In or Sign in with Apple, Firebase Authentication receives account information such as your email address, display name when supplied by the provider, and account identifiers. We store your user ID, email, account status, AI consent, credit balance, rewards, referral information, and usage counters in Firebase services to operate your account and prevent abuse.

Device and other identifiers

The app uses Android ID on Android, identifier for vendor on iOS, or a locally generated installation identifier as a fallback. These identifiers are transmitted to Cloud Firestore and recorded with credit and reward claims to prevent repeated introductory bonuses, coupon claims, and other abuse. Firebase services also process installation and app-instance identifiers. Advertising services may process advertising ID, app set ID, and other device or account identifiers.

Usage, diagnostics, and approximate location

Firebase Analytics records screen views, feature interactions, generation and reward events, and purchase-related events. Firebase Crashlytics receives crash reports, stack traces, error messages, diagnostic logs, device and operating-system information, and installation identifiers. Google Mobile Ads (AdMob) processes IP addresses, identifiers, ad and app interactions, and diagnostic and performance information to deliver and measure ads, analyze performance, and prevent fraud. IP addresses may be used to estimate approximate location. VoxSync does not request GPS location access.

Older app releases, including Android version 1.0.28 (61), also send an email address as an Analytics user property after login. The next app update removes this behavior and clears that property for future events. Clearing the property does not erase previously collected events.

Purchases

Google Play or Apple's App Store handles payment. VoxSync stores product IDs, purchase tokens or transaction/order IDs, platform, credit amounts, delivery status, timestamps, and related error information in Firebase to deliver purchased credits, prevent duplicate credit delivery, and investigate purchase problems. We do not receive your payment card number or bank account details.

AI input and audio

When you use AI features, text you provide or select, product information, prompts, scripts, and voice instructions are sent to Google's Gemini API to generate scripts and speech. When you use automatic subtitle alignment, the app uploads the generated speech audio to Gemini for transcription and word timing. The app attempts to delete the uploaded audio file after the alignment request finishes, including when transcription fails. This is not a guarantee that all provider-side logs or copies are immediately erased.

Your Gemini API key is stored on your device using secure storage and is sent to Google to authenticate requests. Google's handling of AI input and output depends on the API service and your billing configuration: unpaid services may use content to improve Google's products and may involve human review; paid services have different processing terms. See the Gemini API terms. Do not submit confidential or sensitive personal information to unpaid AI services.

Support reports

If you submit a problem report, the app sends your report text, email when provided, device/operating-system description, and app version to our support team using the LINE Messaging API. This is optional and is used to investigate problems and respond to you.

Files and local processing

Selected photos and videos, project files, exported videos, and editing data are processed and stored on your device for editing and export. Selecting a photo or video does not by itself upload your media library to our servers. The AI text and subtitle-audio transfers described above are separate. If you choose to share or export a file to another app or service, that destination handles the shared file under its own privacy practices.

2. Purposes and recipients

  • Firebase Authentication, Cloud Firestore, Cloud Functions, and Remote Config: account access, cloud records, credits, purchases, referrals, configuration, and abuse prevention.
  • Firebase Analytics and Crashlytics: usage measurement, diagnostics, crash investigation, and reliability improvements.
  • Google AdMob: advertising, ad measurement, analytics, and fraud prevention. Its SDK collects and shares information with Google advertising services; ad personalization depends on applicable settings and consent.
  • Google Gemini API: processing AI text, speech generation, and uploaded audio for subtitle timing, subject to the terms linked above.
  • Google Play and Apple App Store: payment processing and purchase administration.
  • LINE: delivery of optional support reports to the VoxSync support team.

Some recipients process information on our behalf; advertising and AI services may also process information under their own terms. We may disclose information when required by law or to protect users and the service. Data may be processed outside your country.

3. Your choices

You choose whether to sign in, buy credits, send a support report, submit AI input, or use subtitle alignment. Account-based features require sign-in; AI features require the relevant input. Automatic advertising, analytics, crash, and installation data collection does not currently have an app-wide opt-out switch. Device advertising controls may let you reset or delete your advertising ID or change ad preferences; they do not disable all identifiers or diagnostics. You can manage camera and media access in device settings.

4. Retention

Account, credit, referral, purchase, and reward records currently have no automatic expiry configured. Account data is retained while your account is active or until a verified deletion request is processed. Limited purchase and anti-abuse records may be retained after account deletion to prevent duplicate credits, resolve disputes, or meet legal obligations; those records currently have no fixed automatic deletion period. You can request a review of retained information through the contact address below.

Analytics, advertising, crash, AI, and support data may remain in provider systems under their retention settings and policies. Deleting your account does not automatically erase all historical SDK events or provider logs. Files on your device remain under your control, including exported copies and files you have shared elsewhere.

5. Request account and data deletion

You can request permanent deletion even if you have uninstalled VoxSync or cannot open the app:

  1. Email atenterprise.development@gmail.com with the subject VoxSync account deletion.
  2. Send the request from your account email when possible and identify the email used to sign in to VoxSync. Do not send passwords, API keys, purchase tokens, or payment card details.
  3. We may ask for information needed to verify account ownership. The support team will process verified requests within 30 days.

The request covers the VoxSync sign-in account and associated account profile, email, preferences/consent records, credit and referral data, and linked cloud usage records, subject to the limited purchase, security, and legal retention described above. Support can explain any information retained and the reason for retention. Deleting your VoxSync account does not delete your Google or Apple account.

Current in-app behavior: the Delete account control in current releases marks your account inactive and signs you out; it does not immediately erase the cloud account or all related records. Use the email procedure above to request permanent deletion. Uninstalling the app alone does not delete cloud records.

6. Security

Our cloud, AI, advertising, and support service connections use HTTPS/TLS to encrypt data in transit. No transmission or storage system is completely secure. Access to account records is subject to authentication and service access controls.

7. Children

VoxSync is not intended for children under 13. If you believe a child has provided personal information, contact us to request review and deletion. AI services have their own age and usage requirements.

8. Updates and contact

We update this policy when our practices change and revise the date above. For privacy questions, corrections, or deletion requests, contact atenterprise.development@gmail.com.
