This Privacy Policy explains how Lahta LLC ("we," "us," or "our") collects, uses, and protects your information when you use the Nimbo mobile application (the "App"). Nimbo is a voice-based AI companion for iOS.

By using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.

Summary

• Your voice never leaves your device as audio. Microphone audio is processed entirely on your device to detect speech and convert it to text. We do not record, store, or transmit raw audio recordings.
• We send the text transcript of what you say to our servers to generate a response.
• Nimbo can remember things you tell it ("memories") to personalize your experience. These are stored on our servers and you can view and delete them at any time.
• We do not require an account, email, name (for login), or password. You are identified only by a random anonymous ID generated on your device.
• We use privacy-conscious analytics* (no session recording, no screen recording, no automatic interaction tracking).
• Nimbo's responses are spoken using an AI-generated synthetic voice.

Information we collect

a. Microphone audio (processed on-device only)

When you start a voice conversation, the App listens through your microphone. This audio is:

• processed locally on your device for voice activity detection and speech-to-text (using on-device speech-recognition models);
• not stored as audio files, and not transmitted to our servers or any third party as audio.

Only the resulting text transcript of your speech is sent to our servers to produce a reply.

b. Conversation content

• The text transcripts of your conversations (both your messages and Nimbo's replies) are sent to and processed by our backend in order to generate responses. To generate each reply, your messages and conversation context (including relevant memories and the name/age you optionally provided) are processed by Google's Gemini API on our behalf — see "Third parties we share data with" below.
• Memories: Nimbo may save facts you choose to share (for example, your preferences or details you mention) so it can personalize future conversations. These memories are stored on our servers and are associated with your anonymous ID.

c. Profile information you provide
