Privacy Policy

📋 1. Who We Are

CryptoTools.site is a free-to-use, browser-based suite of cryptocurrency calculators and cryptography utilities. The site is operated independently and is available at https://cryptotools.site.

🚫 2. Data We Do NOT Collect

We do not collect, store, process, or share any of the following:

• Names, email addresses, or contact details
• IP addresses or device identifiers
• Financial inputs entered into calculators (buy price, sell price, amounts, etc.)
• Cryptographic secrets, keys, or tokens entered into security tools
• Browser fingerprints or user-agent strings for tracking
• Behavioural analytics, mouse movements, or session replays

🧠 3. How Our Tools Work

Every calculation on this site — profit estimates, tax figures, hash generation, AES encryption, RSA key generation, TOTP codes — is performed entirely within your web browser using client-side JavaScript.

Your inputs never leave your device. There is no backend server receiving your financial data or cryptographic secrets. Once you close the tab, all data is permanently gone.

🍪 4. Cookies & Local Storage

CryptoTools.site does not set any first-party cookies for tracking or advertising purposes. We do not use browser local storage to persist your personal data between sessions.

The site uses a dark/light theme preference which may be stored in your browser's session storage to preserve your visual preference — this contains no personal information and is never transmitted to any server.

🌐 5. Third-Party Services

To render the site, we load resources from a small number of reputable third-party CDNs. These services may log your IP address as part of standard CDN operation:

• Google Fonts — for typography (Inter, Space Grotesk). Google Privacy Policy →
• Cloudflare CDN (cdnjs.cloudflare.com) — for open-source JavaScript libraries (CryptoJS, OTPAuth). Cloudflare Privacy Policy →

These are industry-standard, privacy-respecting CDNs and we do not share any user data with them beyond what is inherent to loading a web page.

📡 6. Live API Data

The Gas Tracker and live price feeds fetch real-time data from the Etherscan and CoinGecko public APIs through our server. These requests are made server-to-API and do not include any of your personal information. Your browser only receives the final formatted result.

👶 7. Children's Privacy

CryptoTools.site is not directed to children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has submitted personal information to us, please contact us and we will take steps to delete it.

🔄 8. Changes to This Policy

We may update this Privacy Policy periodically to reflect changes in our practices or for legal reasons. The "Last updated" date at the top of this page will reflect the most recent revision. Continued use of the site after changes constitutes acceptance of the updated policy.
