Privacy Policy

FirstCustomer ("we", "us") is an idea-validation tool: you describe a business idea, and the product researches public web and social content to surface real people talking about that problem, then helps you track them as prospective customers. This page explains what personal data we collect to run that product, why, and how you can get it deleted.

Who this covers

This policy covers the FirstCustomer web app at app.firstcustomer.net and the Android app distributed via Google Play, which is the same app. It does not cover third-party sites we link to or that our research pulls excerpts from (e.g. Reddit, Hacker News, X/Twitter).

Data we collect

When you sign in with Google, we receive and store:

• Your email address, display name, and profile photo URL
• Your Google account ID (used as your unique login identifier — we never see or store your Google password)

When you use the product, we store:

• The idea descriptions and prompts you write, and every message you send in the AI chat (plus the AI's replies) — these are sent to our AI provider to generate responses and are stored so your chat history persists
• Research results our pipeline generates for your idea: excerpts, quotes, and links from public posts and comments (Reddit, Hacker News, X/Twitter, and general web search), matched to your idea
• Prospective-customer records: public usernames and public post history our pipeline identifies as relevant to your idea (this is public social-media data about third parties, not personal contact information you upload) — plus your own outreach notes and status (contacted, replied, etc.)
• Tasks and to-dos you create or that the product generates for you
• In-app notifications (e.g. "your research finished")
• Billing information if you subscribe: your selected plan, payment transaction references, and receipts. Payments in Vietnam are processed by SePay via bank transfer/VietQR — we do not collect or store your card or bank account numbers ourselves
• Basic product-usage telemetry (which screens/features you use, at an event level tied to an internal account ID) — this never includes your email, name, or free-text content you typed

How we use it

We use this data to run the product: sign you in, generate research for your ideas, power the AI chat, run your subscription and billing, notify you when a run finishes, and understand which features are used so we can improve the product.

Who we share it with

We don't sell your data. We use the following service providers to run the app, each only for the purpose below:

• Google — Sign-In / identity verification
• Google Cloud (Vertex AI / Gemini) — powers the AI chat: your chat messages are sent to Google's model to generate a reply
• Tavily and Exa — web search APIs used to find public posts relevant to your idea
• X (formerly Twitter), via xAI's API — used on paid plans to search public X posts relevant to your idea
• Reddit (via a third-party public-archive service) and other public forums — sourced for publicly posted content relevant to your idea
• SePay — processes bank-transfer payments for paid plans
• Cloudflare — hosts the app, our API, and our database
• Amplitude — product analytics, identified only by an internal account ID, never your email or name

Data retention

We keep your account and product data for as long as your account is active. Some records — such as payment receipts — may be kept longer where we're required to for accounting or legal reasons, even after you delete your account. See how to delete your account for what happens to your data when you delete it.

Your choices

You can request a copy of your data or request deletion of your account at any time by emailing support@justvible.app — see Delete your account for the full process. You can also stop using the app at any time by simply not signing back in.

Children

FirstCustomer is a business tool and is not directed at, or knowingly used to collect data from, children under 13.

Changes to this policy

If we make material changes to this policy, we'll update the date at the top of this page.
