๐ก๏ธ Privacy Policy
01 Who We Are
Envoy Marketplace is a local buy-and-sell platform developed and operated by Nextania Technologies Private Limited, a company incorporated in India under the Companies Act 2013. Our app connects buyers and sellers in local communities through an AI-assisted conversational interface powered by Broky โ our in-app AI assistant.
- Registered Office: India

- Support Email: pascalnextania@gmail.com
- Developer Account Email: nextaniatechnologies@gmail.com
Our commitment: This policy explains exactly what data we collect, why we collect it, who we share it with, and how you can control it โ in plain, honest language. We will never surprise you.
02 Information We Collect
Information You Provide Directly
- Display Name: Used to personalise your experience. Shared with the other party only after explicit mutual consent through our in-app consent flow.
- Phone Number: Collected during registration. Used for account identification and, when you explicitly consent, shared with a buyer who expresses interest in your listing. Never shared automatically.
- Location Details: City, district, state, and pincode โ provided during onboarding to show relevant local listings near you.
- Listing Content: Product titles, descriptions, prices, condition, category, and photos you upload when creating a listing.
- Chat Messages: Messages you type in the Broky chat interface, processed by our AI to facilitate your buying or selling flow.
- Wanted Ads: Product or service requests you post on the Wanted Board, including category and budget preferences.
- Ratings & Feedback: Scores and notes submitted after a completed transaction.
- Complaints: Details provided when filing a complaint against another user.
Information Collected Automatically
- Android Device ID: A unique identifier (
Settings.Secure.ANDROID_ID) used solely to identify your account session. Not used for advertising. - GPS Coordinates: Collected only when you grant location permission and the app is in use. Used to show nearby listings and calculate distances. Your precise GPS coordinates are never visible to other users โ only your general area (city/district) is shown.
- FCM Token: A Firebase Cloud Messaging token used exclusively to deliver push notifications to your device.
Camera & Photos
- Camera Permission: Envoy requests access to your device camera (
android.permission.CAMERA) so you can photograph items directly within the app when creating a listing. Camera access is optional โ you may also upload photos from your gallery instead. The app never accesses the camera in the background or when you are not actively taking a listing photo. - Photo Storage: Photos you upload are stored in Google Firebase Storage and publicly visible on your listing.
- AI Moderation: Every photo is reviewed by GPT Vision before publication to ensure it does not contain obscene, violent, or prohibited content. The photo is processed by OpenAI’s API for this purpose only.
- Photo Deletion: Photos are automatically deleted when their associated listing expires or is deleted by you.

04 AI Features โ Broky & Lens Advisor
Broky โ Marketplace Assistant
Broky is powered by OpenAI’s GPT-4o-mini model. When you send a message in the chat, it is transmitted to OpenAI’s API servers for processing.
- What is sent to OpenAI: Your chat messages, your general location (city/district only), and the product context โ the minimum necessary to generate Broky’s response. OpenAI processes this under their Privacy Policy. OpenAI does not use API data to train their models by default.
- We never send to OpenAI: Your phone number, full name, Device ID, payment information, or any sensitive personal identifiers.
Lens โ AI Advisor (Economic, Career & Business)
The Lens advisor feature uses Perplexity AI for real-time data retrieval and OpenAI GPT-4o-mini for structured analysis. When you use Lens, your questions and general conversation context are sent to Perplexity’s API and OpenAI’s API. Perplexity processes data under their Privacy Policy.
We never send to Perplexity or OpenAI: Your phone number, Device ID, payment details, or any personally identifying information beyond your question text.
05 Phone Number Sharing โ Our Consent Flow
We take phone number privacy extremely seriously. Here is exactly how our bilateral consent system works:
In summary: Phone numbers flow in one direction only โ from seller to buyer โ and only with the seller’s explicit, active consent. Never automatic. Never without your knowledge.
