Introduction
This Privacy Policy describes how Skymize Software Private Limited ("we," "us," or "our") collects, uses, and protects information about you when you use the Lumy mobile application (the "App"). By using the App, you agree to the collection and use of information in accordance with this policy.
About Lumy
Lumy is an AI-powered companion application that provides users with interactive AI character personas. Each character in Lumy is an artificial intelligence entity designed to simulate human-like conversation. These AI personas adapt their responses based on the user's conversational style, preferences, and interaction history to deliver a personalized experience. Important: All characters within Lumy are AI-generated personas. They are not real people. Users are interacting with artificial intelligence, not with human beings.
Information We Collect
We collect and use the following categories of information: 1. Device Identifier (Android ID) Your account is created and identified using your device's unique Android ID. We do not collect, store, or use your phone number, email address, or real name for account creation or user identification. 2. Location Data With your explicit permission, we access your device's approximate location (city and country). This data is used solely to personalize your AI interactions — for example, enabling AI characters to reference your geographic context, local time, and cultural nuances to provide a more natural and relevant conversational experience. Your precise GPS coordinates are not stored on our servers. 3. Camera Access With your explicit permission, the App accesses your device camera to allow you to capture and send photos directly within a chat conversation. Photos captured or selected are stored locally on your device and may be sent to our AI service for analysis when shared in a chat. We do not retain or share your photos beyond the scope of the conversation. 4. Photos & Media Access With your explicit permission, the App accesses photos stored on your device so you can select and share images within chat conversations. Shared images may be processed by our AI service to provide relevant responses (e.g., describing an image, answering questions about its content). 5. Chat Data Your chat conversations with AI characters are stored locally on your device using an encrypted local database. A limited context window of recent messages is sent to our AI service for generating responses. We do not permanently store your full conversation history on our servers. 6. Usage Data We collect anonymised usage analytics, including feature usage frequency and session duration, to improve the App experience. This data cannot be used to identify individual users. We do not collect: phone numbers, email addresses, real names, contacts, call logs, SMS messages, or any other personally identifiable information beyond what is described above.
How We Use Your Information
We use the information we collect for the following purposes: • To provide, maintain, and improve the Lumy App and its AI-powered features. • To personalise AI character interactions based on your location and conversational preferences. • To process AI image analysis when you share photos in chat. • To process subscription payments and manage your account. • To enforce usage limits associated with your subscription plan. • To analyse aggregated usage patterns to improve our service. • To detect, prevent, and address technical issues and abuse.
Permissions We Request
• CAMERA: Allows you to capture photos for sharing within chat conversations with AI characters. • READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE: Allows you to select existing photos from your device to share in chat. • ACCESS_COARSE_LOCATION / ACCESS_FINE_LOCATION: Used to detect your approximate location for personalising AI interactions (city-level context). • INTERNET: Required to communicate with our AI service and payment processing. • BILLING: Required for in-app subscription purchases through Google Play Billing. All permissions are requested at runtime with your explicit consent. You may deny any optional permission; however, certain features may not function without them.
AI Processing & Data Handling
When you send a message or image in a chat: • Your recent conversation context (up to 20 messages) is sent to our AI service (powered by xAI Grok) to generate a response. • If you attach an image, it is temporarily encoded and sent to the AI service for visual analysis. The image is not permanently stored on our servers. • The AI service processes your input and returns a response. We do not use your conversations to train AI models. • All data transmission between your device and our servers is encrypted using HTTPS/TLS.
Payment Processing
We process subscription payments through Google Play Billing. Google's Privacy Policy governs the handling of your payment data. We do not store credit card details or payment credentials. We store only your subscription status and plan type, linked to your Device ID.
Single-Device Subscription
Subscriptions in Lumy are tied exclusively to the Device ID of the device on which the purchase was made. This means: • A subscription purchased on one device cannot be accessed or used on a different device. • If you change your device, your subscription will not carry over to the new device. • We are unable to transfer subscriptions between devices or issue refunds due to a device change.
Data Sharing
We do not sell, trade, or otherwise transfer your personally identifiable information to third parties except: • To our AI service provider (xAI) for processing chat responses and image analysis — governed by their data processing agreements. • As required to comply with applicable laws, regulations, or valid legal processes. • To protect the rights, property, or safety of Skymize Software Private Limited, our users, or the public.
Data Retention & Security
• Chat history is stored locally on your device and is not backed up to our servers. • Usage analytics and subscription data are retained for as long as your account is active. • You may request deletion of your server-side account data by contacting support@lumy.chat. • Clearing the App data or uninstalling the App will permanently delete all locally stored chat history. • We implement commercially reasonable technical and organisational measures to protect your data, including encryption in transit and at rest.
Children's Privacy
The App is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately and we will promptly delete it.
