Privacy Policy

Last updated: June 22, 2026

This Privacy Policy describes how Satoshi Institute Inc. ("we," "us," or "our") collects, uses, and shares information when you use BTC Tools (the "Service"). By using the Service, you agree to the practices described below.

1. Information We Collect

We collect only what we need to operate and improve the Service:

Email addresses — when you subscribe to alerts or updates, we store the address you provide.
Analytics data — aggregate, mostly de-identified usage data such as pages viewed, referrer, approximate region, device type, and browser. This may include cookies or similar technologies.
Calculator inputs — values you type into tools generally stay in your browser; we do not store them on our servers unless explicitly stated.

We do not knowingly collect information from children under 13.

2. How We Use Information

To deliver and maintain the Service.
To send alerts, transactional messages, and product updates you have requested.
To measure and improve performance, content, and reliability.
To detect, prevent, and address abuse, fraud, or technical issues.

3. Third-Party Services

We rely on the following processors to run the Service:

Supabase — database, authentication, and email subscription storage.
Analytics providers — privacy-respecting analytics for aggregate traffic measurement.
Hosting and CDN providers — to serve the site globally.

Each processor handles your data under its own terms and privacy policy. We do not sell your personal information.

4. Cookies

We may use cookies and similar technologies for analytics and to remember preferences (for example, to remember you have dismissed our cookie notice). You can control cookies through your browser settings.

5. Your Rights (GDPR / CCPA)

Depending on where you live, you may have the right to:

Access the personal information we hold about you.
Correct inaccurate or incomplete data.
Delete your data ("right to be forgotten").
Restrict or object to certain processing.
Request data portability.
Withdraw consent at any time, where processing is based on consent.
Opt out of the "sale" or "sharing" of personal information (California residents).

To exercise any of these rights, contact us at the address below. We will respond within the timeframe required by applicable law.

6. Data Retention

We retain personal data only as long as needed for the purposes described above or as required by law. Subscription emails are retained until you unsubscribe.

7. Security

We use industry-standard safeguards to protect your information. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

We may update this Privacy Policy from time to time. Material changes will be posted on this page with an updated "Last updated" date.
