Privacy Policy

1. Introduction

Welcome to Abhinandan Ghosh's personal portfolio and software showcase, accessible at https://abhindn.dev. We are committed to protecting your personal information and your right to privacy. This policy explains what information we collect, how it is used, and your rights regarding that data.

2. Information We Collect

We do not collect any personal data when you merely browse this website. We only collect information when you voluntarily choose to sign in to leave a message on the guestbook wall ("Chai Pe Charcha").

When you authenticate using Google Sign-In (OAuth 2.0), we request only the basic, non-sensitive profile scopes (openid, email, profile). From this, we receive:

• Your Name: Displayed publicly next to your guestbook note.
• Your Profile Picture URL: Displayed as an avatar alongside your message.
• Your Email Address: Used solely by Supabase Authentication as a unique identifier to verify real users and prevent automated spam.

3. Google API Limited Use Disclosure

Our application adheres strictly to the Google API Services User Data Policy, including the Limited Use requirements.

• We only use Google account data to provide the user-facing guestbook feature.
• We do not transfer or disclose your Google data to any third parties, except as required by law.
• We do not use your Google data to serve advertisements, build user profiles for marketing, or train machine learning models.

4. Data Storage and Security

User authentication and database records are securely hosted with Supabase (PostgreSQL) using industry-standard encryption in transit (HTTPS/TLS) and at rest. Access to the database is governed by strict Row Level Security (RLS) policies.

5. Cookies and Local Storage

We do not use tracking or advertising cookies. We only use browser Local Storage to remember:

• Your UI theme preference (Dark Mode or Light Mode).
• Your secure authentication session token to keep you logged in.

6. Data Retention and Deletion

Your public guestbook message and avatar remain visible on the site until removed. You have the right to request full deletion of your messages, account, and associated data at any time.

To request the deletion of your message or data, please send an email to ghoshabhinandan290@gmail.com. Requests are processed within 48 hours.
