Privacy Policy

Last updated: March 19, 2026

1. Introduction

BillSight ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our web application.

2. Information We Collect

Account Information: When you sign up, we collect your name, email address, and profile picture (if using Google sign-in). If you create a local account, we store a securely hashed version of your password — we never store your password in plain text.

Usage Data: We track the number of bill analyses you perform each month to manage free tier limits.

Payment Information: If you upgrade to Pro, payment is processed by Stripe. We do not store your credit card number, expiration date, or CVV on our servers. Stripe handles all payment data under their own Privacy Policy.

3. Medical Documents & Health Data

We do not store your medical documents. When you upload a bill for analysis:

The file is temporarily held in server memory only during processing.
The file is sent to our AI provider (Anthropic) for analysis.
The file is immediately deleted from our servers after processing completes — whether the analysis succeeds or fails.
We do not save, copy, archive, or back up your uploaded files.
We do not store the content or text extracted from your bills in our database.

We do not sell, rent, share, or trade your health data or medical documents with any third party for marketing or advertising purposes.

3a. Chat Conversations

Chat conversations are not stored on our servers. When you use the BillSight Assistant chat feature:

Chat messages are kept in your browser session memory only.
Messages are sent to our AI provider (Anthropic) to generate responses, but are not saved in our database.
Chat history is cleared when you close or refresh the page.
We track the number of chat messages sent per month for rate limiting purposes, but not the content of those messages.

4. How We Use Your Information

To provide and maintain the BillSight service
To manage your account and subscription
To enforce usage limits for free tier accounts
To communicate with you about your account (if necessary)

5. Third-Party Services

We use the following third-party services:

Anthropic (Claude AI): Processes your uploaded bills to generate analyses. Documents are sent via encrypted API calls and are subject to Anthropic's Privacy Policy.
Stripe: Handles payment processing for Pro subscriptions.
Google OAuth: Provides sign-in authentication. We only receive your name, email, and profile picture.
Google AdSense: Displays advertisements to free tier users. AdSense may use cookies to serve relevant ads.

6. Cookies

We use a session cookie to keep you logged in. Third-party services (Google AdSense, Google OAuth) may set additional cookies. You can manage cookie preferences in your browser settings.

7. Data Security

We implement reasonable security measures to protect your personal information, including encrypted connections (HTTPS), secure password hashing (bcrypt), and secure session management. However, no method of transmission over the Internet is 100% secure.

8. Data Retention

Account information is retained as long as your account is active. Uploaded medical documents are deleted immediately after processing. You may request deletion of your account by contacting us.

9. Children's Privacy

BillSight is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
