Privacy Policy
Introduction
IFS Voice ("we," "our," or "us") is operated by Aiden Buis, located at Gansstraat 170, 3582 EP Utrecht, The Netherlands. We are committed to protecting your privacy and being transparent about how we handle your data.
This Privacy Policy explains how we collect, use, and protect your information when you use the IFS Voice mobile application. By using IFS Voice, you agree to the data practices described in this policy.
Our Privacy-First Approach
IFS Voice is designed with your privacy as a core principle:
- Your conversations are not saved by us. Session transcripts and messages are stored encrypted on your device only.
- No personal identification required. We use anonymous device identifiers, never collecting your name, email, or other identifying information.
- Audio is processed, not stored. Voice recordings are immediately deleted after transcription and speech synthesis.
- You control your data. All personal session data remains on your device and can be deleted at any time through the app settings.
Information We Collect
1. Data Stored Locally on Your Device (Encrypted)
The following information is stored only on your device using industry-standard encryption (SQLCipher):
- Session transcripts and conversation history
- Identified IFS parts and their attributes
- Session insights and notes
- App preferences and settings
- First name (if provided during onboarding)
Important: This data never leaves your device except during real-time processing (see below) and is never stored on our servers.
2. Data Temporarily Processed (Not Stored)
During active sessions, the following data is processed in real-time but immediately deleted:
- Voice recordings: Sent to DeepInfra for speech-to-text transcription, then immediately deleted
- Conversation context: Sent to DeepInfra for AI response generation, then immediately deleted
- Text responses: Sent to DeepInfra for text-to-speech synthesis, then immediately deleted
3. Anonymous Usage Data (Stored on Backend)
To provide the service and manage usage limits, we collect minimal anonymous data:
- Device identifier: Anonymous unique ID (not linked to your identity)
- Session duration: Total minutes used per day
- Session count: Number of sessions started
- Subscription status: Trial, active, or expired (via RevenueCat)
- Deep Dive token balance: Remaining special session credits
- Timezone: For accurate daily usage tracking
- Last seen timestamp: When you last used the app
Note: This data contains no conversation content, personal information, or identifying details beyond the anonymous device ID.
4. Analytics and Crash Reports
We use PostHog for anonymous analytics and crash reporting to improve app stability and user experience. This includes:
- App crashes and errors (no personal data included)
- Feature usage patterns (anonymous)
- Device type and operating system version
5. Payment Information
Subscription payments are processed through RevenueCat and Apple's App Store (or Google Play Store). We never see or store your payment card details. RevenueCat may share subscription status (active, trial, expired) with us to enable features based on your subscription tier.
How We Use Your Information
We use the collected information solely to:
- Provide voice-guided IFS therapy sessions
- Enforce daily usage limits and Deep Dive token system
- Manage subscription access and trials
- Improve app performance and fix bugs
- Understand anonymous usage patterns to enhance features
We never: Sell your data, use it for advertising, share conversation content with third parties, or train AI models on your sessions.
Third-Party Services
IFS Voice integrates with the following third-party services:
DeepInfra (AI Processing)
We use DeepInfra for:
- Speech-to-text transcription (Mistral Voxtral)
- AI-powered IFS guidance (DeepSeek-V3.1)
- Text-to-speech synthesis (Kokoro TTS)
Audio and text are sent to DeepInfra's API, processed in real-time, and immediately deleted. DeepInfra does not store your data. See their privacy policy at: https://deepinfra.com/privacy
RevenueCat (Subscription Management)
We use RevenueCat to manage subscriptions and trials. They process purchase data from the App Store/Play Store and share subscription status with us. See their privacy policy at: https://www.revenuecat.com/privacy
PostHog (Analytics)
We use PostHog for anonymous crash reporting and usage analytics. No personal or conversation data is sent. See their privacy policy at: https://posthog.com/privacy
Apple App Store / Google Play Store
Payment processing and subscription management are handled by Apple/Google. We receive only subscription status information.
Data Security
We implement industry-standard security measures:
- Local encryption: All session data on your device is encrypted using SQLCipher
- HTTPS/TLS: All data transmission is encrypted in transit
- Minimal data retention: We only store anonymous usage statistics, never conversation content
- Secure API communication: Backend uses JWT authentication and rate limiting
While we take extensive precautions, no method of electronic storage or transmission is 100% secure. We cannot guarantee absolute security but continuously work to protect your data.
