Privacy Policy

Last updated: March 2026

Introduction

OfferLetter.ai ("we," "our," or "us") is operated by Vibing World Inc., a corporation registered in the State of Delaware, United States. We are committed to protecting your privacy. This Privacy Policy explains how our application handles information when you use our AI-powered interview coaching and offer letter analysis tools.

Client-Side Architecture

OfferLetter.ai is built on a fully client-side architecture. The application runs entirely in your web browser. We do not operate backend servers that store, process, or retain your personal data. All interactions with AI models happen directly from your browser to the AI provider's API using your own API key.

Information We Do Not Collect

Because of our client-side design, we do not collect, store, or have access to:

API Key Storage

When you provide your Anthropic Claude API key, it is stored exclusively in your browser's localStorage. This key never leaves your device except when your browser sends requests directly to the Anthropic Claude API on your behalf. We cannot access, read, or retrieve your API key at any time. You can delete your stored API key at any time by clearing your browser's localStorage or using the application's settings.

AI API Communication

When you use OfferLetter.ai's analysis or coaching features, the text you input is sent directly from your browser to the Anthropic Claude API using your own API key. This communication occurs over HTTPS encryption. We do not proxy, intercept, log, or store any of these requests or responses. Your data relationship for AI processing is directly between you and Anthropic, subject to Anthropic's Privacy Policy.

Cookies and Tracking

OfferLetter.ai does not use cookies of any kind. We do not deploy session cookies, tracking cookies, analytics cookies, or advertising cookies. We do not use any third-party tracking scripts, pixels, beacons, or analytics services. The only browser storage mechanism we use is localStorage for your API key preference, which is not a cookie and is not transmitted to any server automatically.

Data Retention

We do not retain any user data on servers because we do not collect any. Information stored in your browser's localStorage persists until you clear it manually or clear your browser data. You maintain full control over all data at all times.

Third-Party Services

The application interacts with the following third-party services:
