Privacy Policy

Effective Date: March 23, 2026 Last Updated: March 23, 2026

Whisper Me (“we,” “us,” “our”) operates the Whisper Me mobile application (the “App”). This Privacy Policy describes what personal data we collect, how we use it, who we share it with, how long we keep it, and your rights under applicable laws including the EU General Data Protection Regulation (GDPR), Korea’s Personal Information Protection Act (PIPA), and the California Consumer Privacy Act (CCPA).

By using the App, you agree to the collection and use of information as described in this policy. If you do not agree, do not use the App.


1. Data Controller

JoCoding, Inc. 16 Wausan-ro 29-gil, Mapo-gu, Seoul, South Korea highball@jocoding.net

For Korea PIPA purposes, the personal information protection officer is: highball-jo (highball@jocoding.net)


2. Data We Collect

2.1 Account Data

We collect the following when you create an account:

Data Point Source Required
Email address You provide it (email sign-up) or it is shared by Google/Apple Yes
Password You provide it (email sign-up only); stored as a cryptographic hash, never in plaintext Yes (email sign-up)
Display name Shared by Google or Apple during OAuth sign-in No
Profile photo URL Shared by Google during OAuth sign-in No
Google account ID Google OAuth Only if using Google sign-in
Apple user ID Apple Sign-In Only if using Apple sign-in

2.2 Profile Data

Data Point Source Purpose
Preferred language You select or we detect from your device locale Display the App in your language
Theme preference You select (system, light, or dark) Display settings
Timezone (IANA format, e.g., “Asia/Seoul”) Auto-detected from your device on each app launch Enable your AI companion to reference time naturally when you enable “Your Real Time” mode

Timezone and location: We collect your device timezone, not your GPS location. However, a timezone can indicate your approximate geographic region.

2.3 Companion Configuration Data

When you create an AI companion, we store:

  • Companion name (you choose)
  • Personality type (caring, playful, intellectual, or adventurous)
  • Gender (male, female, or nonbinary)
  • Voice selection (a voice ID referencing a pre-built voice)
  • Language (one of 24 supported languages)
  • Time awareness mode (timeless or real-time)
  • Response length preference (short, medium, or long)
  • Custom instructions (up to 500 characters of free-text guidance you write for the companion)
  • Companion avatar image (optional)

2.4 Conversation and Call Data

This is the most sensitive category of data we collect.

During every voice call or text conversation, we collect and store:

Data Point Storage Location Retention
Full conversation transcript (every message you send and every response the companion generates) Our database (Supabase) Until you delete your account
Call metadata (duration, start/end time, call status) Our database Until you delete your account
Twilio call session ID Our database Until you delete your account

We do NOT record or store audio. Voice audio is streamed in real time through our processing pipeline and is never written to disk or saved to any storage system. Only the text transcript is retained.

2.5 AI-Extracted Memory Data

After each call or text conversation, our server processes the conversation to extract and store:

Data Type Description Example Retention
User profile facts Structured facts about you extracted by AI “Job: software engineer,” “Pet: dog named Max,” “Favorite food: ramen” Until you delete your account
Call summaries 2-3 sentence AI-generated summary of each call “Discussed weekend plans and work stress. Mood was upbeat.” Until you delete your account
Emotional tone AI-assessed emotional tone of each call “happy,” “anxious,” “playful” Until you delete your account
Topics discussed List of topics from each call [“work”, “family”, “travel plans”] Until you delete your account
Unresolved threads Topics left unfinished in a call [“birthday gift ideas”] Until you delete your account
Semantic embeddings Mathematical vector representations of call summaries (1536-dimensional vectors) used for memory retrieval Not human-readable Until you delete your account
Relationship arc AI-generated narrative of how your relationship with the companion has evolved, including milestones and inside jokes “The relationship has deepened over 20 calls…” Until you delete your account

Important: This memory system exists so your companion can remember you across conversations. The AI extracts facts, preferences, emotional patterns, and relationship history from your conversations to provide a personalized experience.

2.6 Device and Technical Data

Data Point Collected Purpose
Device timezone Yes (auto-detected each app launch) Time-aware companion responses
Device locale Yes (on first launch) Language detection
Microphone audio Streamed in real time, never stored Voice calls
IP address Incidentally, via standard HTTPS connections Server infrastructure
Device identifiers (UDID, advertising ID) No N/A
GPS location No N/A
Contacts No N/A
Photos or camera No N/A
Browsing history No N/A

2.7 Data We Do NOT Collect

  • We do not use analytics SDKs (no Mixpanel, Amplitude, Segment, Firebase Analytics, or similar)
  • We do not use crash reporting services (no Sentry, Crashlytics, or similar)
  • We do not use advertising SDKs or tracking pixels
  • We do not collect device identifiers or advertising IDs
  • We do not use cookies (the App is a native mobile application)
  • We do not record or store audio from calls

3. How We Use Your Data

We use your data for the following purposes:

Purpose Legal Basis (GDPR) Data Used
Provide the service — authenticate you, connect calls, generate AI responses Performance of contract (Art. 6(1)(b)) Account data, conversation data, companion config
Companion memory — enable your companion to remember facts, preferences, and relationship history across calls Performance of contract (Art. 6(1)(b)) Conversation transcripts, extracted profile facts, call summaries, relationship arc
Time-aware responses — allow your companion to reference the current time naturally Performance of contract (Art. 6(1)(b)) Device timezone
Language localization — display the App in your language Performance of contract (Art. 6(1)(b)) Device locale, preferred language
Security — protect against unauthorized access Legitimate interest (Art. 6(1)(f)) Authentication tokens, session data

We do not use your data for:

  • Advertising or ad targeting
  • Selling to third parties
  • Training AI models (see Section 4 for third-party AI provider policies)
  • Profiling for automated decision-making that produces legal effects

4. Third-Party Services and Data Sharing

We share data with the following third-party service providers, solely to operate the App. We do not sell your personal data to any third party.

4.1 AI and Voice Processing (Server-Side Only)

These services receive data only from our server. Your device never communicates with them directly (except Twilio for call connectivity).

Service Data Sent Purpose Data Retention by Provider
xAI (Grok) System prompt containing companion personality, your extracted profile facts, recent call summaries, relationship arc, conversation history (last 20 messages), and your current message Generate AI companion responses; post-call extraction of user facts and call summaries Refer to xAI’s privacy policy. xAI states it may use API inputs to improve models unless you opt out
Deepgram Real-time audio stream (mu-law encoded, 8kHz) from your microphone during calls Speech-to-text transcription Refer to Deepgram’s privacy policy. Audio is processed in real time and not stored by default for API customers
MiniMax AI-generated response text, voice ID, language code Text-to-speech synthesis (companion’s voice) Refer to MiniMax’s privacy policy
OpenAI Call summary text (2-3 sentences per call) Generate semantic embedding vectors for memory retrieval Refer to OpenAI’s API data usage policy. OpenAI states it does not use API data to train models
Twilio Real-time voice audio (bidirectional), call metadata (session ID, duration) VoIP call connectivity and media streaming Refer to Twilio’s privacy policy

What this means in practice: When you speak during a call, your audio is streamed to Deepgram for transcription. The resulting text, along with your conversation history and companion memory context, is sent to xAI’s Grok model to generate a response. That response text is sent to MiniMax to produce audio, which is streamed back to you via Twilio. After the call, a summary is sent to OpenAI for embedding generation and to Grok for memory extraction.

4.2 Authentication

Service Data Sent Purpose
Google (if you use Google sign-in) OAuth token, nonce Verify your Google identity
Apple (if you use Apple sign-in) Identity token Verify your Apple identity

4.3 Infrastructure

Service Data Stored Purpose
Supabase All persistent user data (database and file storage) Managed PostgreSQL database, authentication, real-time subscriptions
Fly.io or Railway Server application and logs (no persistent user data) API server hosting
Expo (EAS) Application source code during builds Mobile app build and distribution

4.4 No Other Sharing

We do not share your data with:

  • Advertisers
  • Data brokers
  • Social media platforms
  • Law enforcement (unless required by valid legal process — see Section 8)
  • Any other third parties not listed above

5. Data Storage and Security

5.1 Where Data Is Stored

  • Database: Supabase-managed PostgreSQL (cloud infrastructure, region: ap-northeast-2 (Seoul))
  • Server: Hosted on Railway (ap-southeast-1 (Singapore))
  • Device: Authentication tokens stored in iOS Keychain / Android Keystore via platform-native encrypted storage. No conversation data is cached on your device.

5.2 Security Measures

  • Encryption in transit: All data transmitted over HTTPS/TLS (including audio streams via secure WebSocket connections)
  • Encryption at rest: Database encryption managed by Supabase’s infrastructure
  • Row-Level Security (RLS): Every database table enforces row-level security policies. You can only access your own data. Even with a valid session, one user cannot query another user’s conversations, memories, or companion data
  • API key isolation: All AI service API keys (xAI, OpenAI, Deepgram, MiniMax, Twilio) are stored server-side only and never exposed to the mobile app
  • Secure token storage: Authentication tokens are stored using platform-native secure storage (iOS Keychain, Android Keystore), never in unencrypted local storage
  • No audio recording: Voice audio is processed as a real-time stream and never persisted

5.3 Data Breach Notification

In the event of a data breach affecting your personal data, we will notify you and the relevant supervisory authorities within the timeframes required by applicable law (72 hours under GDPR, without delay under PIPA).

11. Sensitive and Behavioral Data Disclosure

This section is important. Please read it carefully.

The nature of an AI companion app means that conversations are inherently personal. The data we collect and process includes:

  • Emotional and psychological content: Your conversations may reveal emotional states, mental health concerns, personal anxieties, relationship issues, and other sensitive topics. Our AI extracts and stores emotional tone assessments and personal facts from these conversations.
  • Intimate content: The App permits explicit and intimate conversations. Transcripts of such conversations are stored in our database. AI-extracted facts from these conversations may include intimate preferences or relationship details.
  • Behavioral patterns: Over time, the companion memory system builds a detailed profile of your personality, preferences, habits, relationships, work life, and emotional patterns.
  • Relationship simulation data: The relationship arc narrative tracks how your simulated relationship with the AI evolves, including milestones and inside jokes.

This data is collected solely to provide the companion experience. We do not use it for advertising, profiling for third-party purposes, or any use beyond operating the App.

Under GDPR, some of this data may qualify as “special category” data (Art. 9). We process it on the basis that you have given explicit consent by choosing to engage in conversations with the companion and by agreeing to this Privacy Policy.

Under PIPA, this data is treated as “sensitive information” and is processed with your consent.


12. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by:

  • Posting the updated policy in the App
  • Updating the “Last Updated” date at the top
  • Sending an in-app notification for significant changes

Your continued use of the App after changes constitutes acceptance of the updated policy.


13. Contact Us

For privacy-related inquiries, data access requests, or complaints:

Email: highball@jocoding.net Address: 16 Wausan-ro 29-gil, Mapo-gu, Seoul, South Korea

If you are in the EU/EEA, you have the right to lodge a complaint with your local data protection authority. If you are in Korea, you may file a complaint with the Personal Information Protection Commission (PIPC). If you are in California, you may contact the California Attorney General’s office.


14. Data Protection Officer

At our current scale, a formal DPO appointment is not required. The personal information protection officer (highball-jo, highball@jocoding.net) handles all data protection inquiries. We will appoint a dedicated DPO if and when required by applicable law.
