Privacy Policy

Last updated: April 15, 2026

1. Information We Collect

Account Information

When you create an account, we collect your email address and a hashed password. We never store or have access to your plain-text password. Authentication is handled by Supabase, a third-party authentication provider.

Usage Data

We store your scan history, including the product types you search for, the niches scanned, and the results generated. This data is used to provide the scan history feature and improve the Service.

Payment Information

Payment processing is handled entirely by Stripe. We do not store, process, or have access to your credit card number, bank account details, or other financial information. We receive only your Stripe customer ID and subscription status.

2. How We Use Your Information

• To provide and maintain the Service
• To manage your account and subscription
• To enforce usage limits (free tier scan counts)
• To store your scan history for your reference

We do not sell, rent, or share your personal information with third parties for marketing purposes.

3. Third-Party Services

NicheSignal uses the following third-party services to operate:

• Supabase — authentication and database hosting
• Stripe — payment processing
• Vercel — website hosting
• Railway — backend API hosting

Each of these services has its own privacy policy governing how they handle data.

4. Data Sources

NicheSignal analyzes publicly available data from Reddit (public subreddit data and posts), Wikipedia (public pageview statistics), and e-commerce platforms (public search result counts). No private or authenticated data from these platforms is accessed.

5. Data Retention

Your account data and scan history are retained for as long as your account is active. If you delete your account, your data will be removed within 30 days.

6. Data Security

We implement appropriate security measures to protect your data, including:

• HTTPS encryption for all data in transit
• Hashed passwords (never stored in plain text)
• Row-level security on the database (users can only access their own data)
• API keys and secrets stored as environment variables, never in source code

7. Your Rights

You have the right to:

• Access your personal data
• Export your scan data (CSV export feature)
• Request deletion of your account and associated data
• Cancel your subscription at any time

8. Cookies

NicheSignal uses local storage (not cookies) to maintain your login session. We do not use tracking cookies or third-party analytics cookies.

9. Children's Privacy

The Service is not intended for users under 18 years of age. We do not knowingly collect personal information from children.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Continued use of the Service after changes are posted constitutes acceptance of the updated policy.
