Privacy Policy for Tonify

1. Overview

Artos Studio (“we,” “us,” or “our”) built Tonify as an AI-powered communication utility without requiring account registration. This Privacy Policy describes what information is processed when you use our mobile or desktop application and how we safeguard your privacy.

2. AI Text Prompts & Voice Synthesis Transmission

• Encrypted Transmission: When you tap Speak, Write, Translate, or Correct, your submitted text and selected style/voice parameters are transmitted over encrypted HTTPS (TLS) to our secure backend API and third-party cloud AI/TTS processors strictly to generate your requested text or .mp3 speech audio.
• Ephemeral Server Audio Cleanup: Generated .mp3 voice files cached temporarily on our API server to stream or download to your phone are automatically deleted via a strict 30-minute time-to-live (TTL) purge routine.
• No Model Training: We do not sell your prompts or generated outputs, and we configure our API workflows so submitted user text is used solely for transient inference rather than training public foundation models.
• Abuse Prevention: Our server temporarily evaluates request IP addresses in volatile memory for sliding-window rate limiting (preventing automated abuse) and prunes transient counters automatically within 24 hours.

3. Local Device Storage & Preferences

Tonify stores your convenience data locally on your device so you can replay voiceovers and reuse drafts offline:

• History & Exported MP3s: Past generations and downloaded .mp3 files are stored locally in your device's app storage (or user-selected export folder).
• Encrypted Preferences: App settings, daily usage counters, and subscription status cache are persisted locally in encrypted device preferences.

4. Analytics, Advertising & In-App Billing SDKs

• Firebase Analytics: Used to measure aggregate feature usage (e.g., Speak vs. Translate funnel metrics) and improve app stability without collecting personal names or email addresses.
• Google AdMob (AD_ID): Free-tier sessions display banner, interstitial, and rewarded video ads via Google Mobile Ads. AdMob may access your device Advertising ID and coarse IP-derived country/region in accordance with Google's privacy policy and your regional consent choices (GDPR/UMP). Paying Tonify Pro subscribers see zero advertisements.
• Google Play Billing & Apple StoreKit: All subscription transactions are processed directly by Google Play or Apple. Artos Studio never receives or stores your credit card or payment credentials.

5. Permissions Requested

• INTERNET: Required to communicate with AI/TTS servers, analytics, billing, and ad services.
• READ_MEDIA_AUDIO / Storage (OS-dependent): Used when exporting or opening your generated MP3 audio files on your device.
• POST_NOTIFICATIONS (optional): Used for helpful status updates when permitted by the user.
• PROCESS_TEXT / Share Intent: Receives only the specific text snippet you actively highlight and share into Tonify from another app.

7. Children's Privacy & Policy Updates

Tonify is not directed to children under 13 years old (or the minimum digital consent age in your jurisdiction). We may update this Privacy Policy periodically; updates take effect when published with a revised Effective Date at https://www.artosstudio.com/tonify/privacy/.
