Privacy Policy

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

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.

3.3 Meeting Audio in the Browser Extension

When you start a session in the Hinty Voice Assistant extension, it captures the audio of the meeting tab (the other participants) and of your microphone and streams it to Hinty for speech recognition and hints. Capture runs only during a session that you start and ends when you stop it. We do not store the audio recordings.

3.4 Analysis of the Shared Screen (optional, paid plans)

When you switch it on, Hinty sends screenshots of the content shared in the meeting to AI providers (Groq, OpenAI) to read the text and prepare hints. The screenshots are not stored by us; the recognised text is kept only in memory for the duration of the session. You are responsible for having the right to process content shared by other participants.

3.5 Telling Your Voice Apart in Single-Microphone Mode

When one microphone hears both you and the other person (for example the mobile app on the table) and you say "Hinty, it's me" or mark one of your statements with "These are my words", our server compares the sound of the following statements with that one statement, only to tell which words in this conversation are yours and which are the other person's. The comparison runs on our own server, in memory, during the conversation only, and is deleted when the session ends. We do not save recordings or voice characteristics, we do not create a permanent voiceprint, we do not use it to identify you, and we do not send it to anyone.

4. Document Processing & Vector Storage

When you upload a PDF document:

• Text is extracted on our servers and the original PDF file is deleted right after processing
• The text is sent to Groq, an AI provider, which splits it into short, titled parts
• These text parts and their mathematical vectors (embeddings) are stored in Pinecone, a vector database, so that hints can quote your own materials
• The stored parts are linked to your account and used only to answer during your own sessions
• When you delete a document, all its text parts and 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.

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.
