1. Who we are
Rudina (“we”, “our”, “us”) operates the Razvigor AI Chat application and this website. Rudina is an individually-operated business based in Serbia, and is the data controller for personal data processed through this service. This policy explains what personal data we collect, why we collect it, and how we handle it.
2. Data we collect
We collect the following data when you create an account or purchase a subscription:
- Email address - used to identify your account and send transactional emails.
- Display name - optionally provided during registration.
- Subscription data - subscription status, plan, billing period, and trial end date, stored so the app can verify your access.
- Payment identifiers - your Lemon Squeezy customer ID, subscription ID, and (for one-time token pack purchases) order ID. We do not store card numbers or full payment details; those are handled by Lemon Squeezy.
- Profile photo - optionally uploaded by you and stored in Firebase Storage. Used only to display your avatar in the application.
- Usage data - token consumption counts, monthly spend totals, and optional spend limit settings, stored server-side to enforce plan limits and display usage in your dashboard.
- Conversation content - the text of your messages and the AI's responses, along with any images you attach, are stored in our database (Firestore) and Firebase Storage so your conversation history is available across your devices and sessions.
- Voice recordings - if you use the dictation feature, your audio is uploaded once to our server to be transcribed into text. The audio itself is not stored after transcription completes.
- Device and app information - basic technical data such as app version and operating system, sent with requests to our server to keep the service working correctly.
If you use the API Keys plan, your messages are sent directly from the app to the AI provider of your choice using your own API keys, and are not stored on our server. If you use the Free or Pro plan's built-in AI proxy, your messages pass through our server to route them to the underlying provider (Google, OpenAI, or Anthropic) and stream back a response.
3. How we use your data
- To create and manage your account.
- To verify your subscription status and grant access to the app.
- To process payments and handle subscription lifecycle events (renewals, cancellations, refunds).
- To send transactional emails related to your account or subscription.
We do not sell your personal data or use it for advertising.
4. Third-party services
We use the following third-party services which may process your data:
- Firebase / Google - provides authentication and our database (Firestore). Subject to Google's Privacy Policy.
- Lemon Squeezy - acts as the Merchant of Record and processes all payments. Subject to Lemon Squeezy's Privacy Policy.
- Google, OpenAI, and Anthropic - if you use the Free or Pro plan's built-in AI proxy, your conversation messages are forwarded to whichever of these providers powers the model you selected, solely to generate a response. Subject to each provider's own privacy policy.
- Google (Gemini) - if you use the voice dictation feature, your audio recording is sent to Google's Gemini model solely to transcribe it into text, regardless of which AI provider you have selected for chat.
These services are based in the United States. If you are in the EU or EEA, your personal data may be transferred to and processed in the United States. These transfers rely on Standard Contractual Clauses approved by the European Commission.
