Privacy Policy

1. Who we are

Bitmern Solo ("we," "us," or "our") operates a solo cryptocurrency mining pool at bitmernsolo.com and app.bitmernsolo.com. This policy explains how we collect, use, and protect your information when you use our services.

2. Information we collect

Account information

• Email address (for authentication and notifications)
• Display name (optional)
• Timezone preference

Wallet addresses

You provide cryptocurrency wallet addresses to receive mining payouts. These are public blockchain addresses and are stored in your account profile.

Mining data

• Worker names and configurations
• Hashrate, shares submitted, and performance metrics
• Earnings and payout history
• Alert preferences and alert history

Technical data

• IP address and browser user agent (via server logs)
• Authentication session tokens

3. How we use your information

• To operate the mining pool and process payouts to your wallet
• To display your mining statistics and performance data
• To send alert notifications (worker offline, hashrate drop, payouts) when enabled
• To authenticate your account and maintain session security
• To improve our infrastructure and debug issues

4. Third-party services

We use the following third-party services to operate:

• Supabase — authentication, database, and serverless functions
• Vercel — web application hosting
• Resend — transactional email delivery (alert notifications)
• CoinGecko — cryptocurrency price data (no user data is shared)

Each service processes data according to their own privacy policies. We do not sell, rent, or trade your personal information to any third party.

5. Data retention

We retain your account data for as long as your account is active. Mining performance data (hashrate history, earnings) is retained indefinitely to provide historical statistics. If you delete your account, your profile and alert configurations are removed. On-chain data (payouts, transactions) is immutable and remains on the respective blockchains.

6. Security

All connections to our services are encrypted via TLS/HTTPS. Passwords are hashed and never stored in plaintext. Database access is protected by row-level security policies, ensuring users can only access their own data. We do not store private keys or seed phrases.

7. Cookies

We use essential cookies for authentication sessions. We do not use advertising or tracking cookies. See our Cookie Policy for details.

8. Your rights

You can:

• Access and update your profile information at any time through your account settings
• Enable or disable email notifications for each alert type
• Request deletion of your account by contacting us
• Export your mining data by contacting us

9. Changes to this policy

We may update this policy from time to time. If we make significant changes, we will notify registered users by email. Continued use of the service after changes constitutes acceptance of the updated policy.
