Quick Reference Summary

1. Introduction & Overview

Welcome to Simulated AI Calls (referred to as "the App", "we", "us", or "our"), published by TechFusion. We are committed to protecting your privacy and being fully transparent about how data is handled.

This Privacy Policy explains the types of information processed when you use Simulated AI Calls, how it is used, and the choices available to you.

2. 100% Simulated Call Experience

Simulated AI Calls is strictly a simulation and pretend-play habit coach utility intended to assist parents and guardians in motivating healthy child routines (e.g., bedtime routines, finishing meals, cleaning toys, listening to parents).

• No Real Calling: The App does not place, route, or receive real cellular, PSTN, or VoIP telephone calls.
• No Telephony Access: The App cannot dial phone numbers, access contacts, send or read SMS messages, or intercept real telephone communications.
• Non-Emergency: The App CANNOT contact emergency services (such as 911, 112, 999, 113, 114, 115). It must never be used for real emergency purposes.

3. Information We Collect and Store Locally

We believe in minimal data processing. We do not require user registration, email addresses, or cloud account creation.

All user-generated information is stored exclusively on your local device using standard platform local storage (SharedPreferences on Android, UserDefaults on iOS):

• Kid Profiles: Name or nickname, avatar letter/color, caller preference, and default topic.
• Custom Topics & Scripts: User-written scenario titles and speech scripts.
• Preferences: UI theme style (Auto / iOS / Android), speech delay duration (0s, 5s, 10s, 30s), active language (en or vi), and adult consent verification status.

4. AI Voice Generation & Text-to-Speech Processing

To provide realistic audio when an incoming call is answered, Simulated AI Calls utilizes a Neural AI Voice Engine powered by state-of-the-art open-source speech models:

• VieNeu-TTS: Vietnamese synthesis by @pnnbao97
• Kokoro-82M: English synthesis by @hexgrad

How Speech Synthesis Works:

1. When a call is triggered or a profile is saved, the App sends the pre-written script text to our secure TTS backend server over encrypted HTTPS (TLS 1.3) protected with cryptographic HMAC-SHA256 request signing.
2. The spoken text contains only the caller's persona script and the optional kid nickname entered locally by the user.
3. The server processes the text transiently in-memory solely to synthesize audio bytes (WAV/MP3).
4. Synthesized audio is returned to the App and cached locally on your device for instant offline replay.
5. No Retention: The TTS backend server does not log, store, sell, or link spoken text or audio to any user identity or device identifier.

5. Advertising & Third-Party SDKs

The App is monetized through advertisements provided by Google AdMob. AdMob may serve:

• Native In-Feed Ads: Displayed within the home configuration screen.
• Interstitial Ads: Full-screen advertisements displayed occasionally upon concluding a simulated call sequence.
• Rewarded Video Ads: Optional short video ads that users may voluntarily choose to watch to unlock additional profile or custom topic slots.

Data Processed by Google AdMob:

Google AdMob may automatically collect and process certain device information, including:

• Device identifiers (such as Google Advertising ID or Apple IDFA/IDFV)
• IP address (used for coarse geographic location and fraud prevention)
• Ad performance and diagnostic metrics (such as impressions, clicks, and load latency)

For detailed information on how Google processes ad data, please review Google's Privacy Policy and Terms.

User Consent (UMP Framework):

In regions with applicable privacy regulations (such as the European Economic Area (EEA), the United Kingdom, Switzerland, and relevant US states), we implement Google's User Messaging Platform (UMP) SDK to request your consent before serving personalized advertisements. If you decline or revoke consent, only non-personalized or contextual ads are requested.

6. Device Permissions

Simulated AI Calls requests only the absolute minimum system permissions necessary to operate:

• INTERNET / ACCESS_NETWORK_STATE: Required to download synthesized TTS audio from our voice API and to load Google AdMob advertisements.
• VIBRATE (Android): Used optionally to simulate realistic ring vibration during incoming calls.

Permissions NOT Requested:

• ❌ No Contacts permission
• ❌ No Microphone or Audio Recording permission
• ❌ No Camera permission
• ❌ No Precise Location (GPS) permission
• ❌ No Phone State / Call Log / Telephony permission
• ❌ No External Storage / Photo Library read access

7. Children's Privacy (COPPA & GDPR-K Compliance)

Simulated AI Calls is designed as a parenting tool operated exclusively by adults (parents, guardians, caregivers aged 18 and older).

• Adult Verification Gate: The App includes a mandatory first-run adult confirmation gate verifying that the operator is 18 years of age or older.
• COPPA (Children's Online Privacy Protection Act): The App does not knowingly collect, solicit, or maintain personally identifiable information from children under 13 years of age.
• GDPR-K: We do not knowingly process personal data belonging to children under 16 years of age in the European Union.
• Any child nickname entered into the app is stored strictly on the parent's device and is used solely for on-device pretend-play voice rendering.

If a parent or guardian becomes aware that personal data has been inadvertently collected without parental consent, please contact us immediately at support@techfusion.dev so we can take prompt corrective action.

8. Data Retention, Control & Deletion

Because all profile data is stored exclusively on your device, you maintain complete sovereignty over your data at all times:

• In-App Deletion: You can edit or delete any Kid Profile or Custom Topic at any time from the app's home screen or topics manager.
• Complete Erasure: Clearing the app data in your device Settings or uninstalling Simulated AI Calls permanently erases all locally stored profiles, audio caches, and settings.
• There are no remote databases, user accounts, or server backups that retain your data after uninstallation.

9. Data Security

We implement technical and organizational security measures to protect data:

• All network communications between the App, the TTS backend, and Google AdMob are secured using standard HTTPS with Transport Layer Security (TLS 1.3) encryption.
• Network API calls to our TTS backend are authenticated using cryptographic HMAC-SHA256 request signing to prevent unauthorized abuse.
• Local application data is sandboxed within the operating system's secure app storage partition.

10. International Privacy Rights (GDPR, CCPA/CPRA, CalOPPA)

Depending on your country or state of residence, you may have specific rights under data protection laws:

• EEA / UK (GDPR): You have the right to access, rectify, restrict, or delete personal data, and to withdraw consent for personalized advertising at any time. Because we do not operate user accounts or store personal data on remote servers, your primary control is managed directly on your device or via the Google UMP consent dialogue.
• California (CCPA / CPRA / CalOPPA): We do not sell or share personal information for financial consideration. AdMob's data collection for interest-based advertising can be controlled via your device's operating system settings ("Opt out of Ads Personalization" on Android, "Ask App not to Track" on iOS).

11. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect enhancements in the App, regulatory changes, or modifications to our third-party services. Any updates will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
