Privacy Policy
Last updated: June 2026
Your Privacy Is Our Priority
Hinty does NOT store your audio recordings, does NOT keep transcription history, and does NOT retain your original documents. All audio processing happens in real-time through certified third-party providers and is immediately discarded. Your PDF documents are converted to anonymous vector embeddings - the original content is never stored on our servers.
1. Introduction & Core Principles
Welcome to Hinty ("we," "our," or "us"), operated by WAAM Sp. z o.o. We are committed to protecting your privacy and ensuring the security of your personal information.
- Data Minimization: We collect only the absolute minimum data required to provide our services.
- No Audio Storage: Your voice recordings are processed in real-time and immediately discarded - we never store audio files.
- No Document Storage: Your PDF documents are converted to mathematical vectors and then deleted - original content is never retained.
- User Control: You can delete your account and all associated data at any time.
2. What We Do NOT Collect or Store
We Do NOT:
- Store any audio recordings of your conversations
- Keep transcription text history or logs from voice sessions (the AI voice assistant)
- Retain original PDF document content on our servers
- Track your location or collect GPS data
- Sell or share your data with advertisers
- Use your data to train AI models
- Store your payment card details (handled entirely by Stripe)
3. Audio Processing & Real-Time Transcription
3.1 How Audio Processing Works
- Real-Time Streaming: Audio is streamed in small chunks directly to transcription providers via encrypted WebSocket connections.
- No Server Storage: Audio chunks pass through our servers only as a relay - they are never written to disk.
- Complete Deletion: When your session ends, all transcription data is immediately purged from memory.
3.2 Transcription Service Providers
| Provider | Data Center | Data Retention | Certifications |
|---|---|---|---|
| Speechmatics | EU (UK/Ireland) | 0 days | ISO 27001, SOC 2, GDPR |
| ElevenLabs | US/EU | 0 days | SOC 2 Type II |
| Deepgram | US | 0 days | SOC 2, HIPAA eligible |
4. Document Processing & Vector Storage
When you upload a PDF document:
- Text is extracted and converted to mathematical vectors (embeddings)
- Original PDF is immediately deleted after processing
- Only vectors are stored - they cannot reveal original content
- When you delete a document, all vectors are permanently removed
5. Hinty Talk – Language Learning with AI Agents
Hinty Talk is our language-learning experience where you practice a foreign language by chatting with AI "friends" (agents). These agents exist for educational purposes only – they simulate natural conversations so you can practice speaking and writing. They are not real people, and the conversations are not monitored by humans.
What This Means for Your Privacy
- Minimal personal data: To use Hinty Talk we only need your email address and a nickname (display name) for login and to personalize your conversations. Nothing more is required.
- No profiling, no advertising: We do not build advertising profiles, we do not sell your data, and we do not share your conversations with third parties for marketing.
- We do not train external AI models on your conversations. Your chats are used only to deliver your own learning experience.
- Educational use only: The AI agents are designed to help you learn a language, not to collect information about you.
5.1 What We Store to Make Learning Work
So that your conversations stay continuous and your progress is saved, we store the chat messages you exchange with the AI agents and basic learning data (for example, vocabulary and grammar review cards generated from your mistakes). This data:
- Is tied only to your account and visible only to you;
- Is used solely to provide conversation continuity and track your learning progress;
- Is processed for AI responses by our language-model providers (see Third-Party Service Providers below);
- Is permanently deleted when you delete your account.
5.2 Schools, Teachers and Groups
If you join Hinty Talk through a school or teacher (for example, using an invitation code), your teacher may see your learning progress for educational purposes. We still collect only the minimal data described above and never use it for any purpose other than supporting your learning.
6. Account & Minimal Data We Store
