Privacy Policy — CRC (Crypto Revenue Calculator)
Last updated: May 2026
This Privacy Policy explains how CRC ("the App") handles your information. By using the App, you agree to this policy.
1. Information We Collect
The App asks users to enter:
- A display name (used only for labeling your results)
- Blockchain wallet addresses (Ethereum/EVM, Bitcoin, and/or Solana)
This information is submitted to our backend server solely to retrieve publicly available blockchain data (transaction history, token balances, and live prices) from third-party APIs.
2. How We Use Your Information
- Wallet addresses are used exclusively to query public blockchain data on your behalf.
- Your name is used only to label your portfolio results within the app session.
- We do not store, log, sell, share, or retain any wallet addresses or personal information after your session ends.
- We do not have access to your private keys, seed phrases, or funds in any way.
3. Exported Files (PDF & Excel)
The App allows users to export their portfolio data as PDF or Excel files. These files are:
- Generated on our server and immediately sent to your device.
- Not stored, saved, or retained on our servers after being sent.
- Saved locally on your device only — we have no access to them once downloaded.
4. Third-Party Services
The App uses the following third-party APIs to retrieve publicly available data:
- Etherscan — Ethereum transaction data
- Alchemy — Token balances
- Helius — Solana data
- Coinbase & Binance — Live and historical price data
- Blockchain.info — Bitcoin data
These services have their own privacy policies. We recommend reviewing them separately.
5. Data Security
All communication between the App and our server is encrypted via HTTPS. We do not store any user data on our servers.
6. Children's Privacy
This App is not directed at children under the age of 13. We do not knowingly collect any information from children.
