Privacy Policy

Effective Date: January 1, 2025 • Last Updated: February 2025

1. Non-Custodial Core Architecture

BlockToolsHub is designed from the ground up as a read-only, non-custodial blockchain utility and educational website. We do not require, request, or support cryptocurrency wallet connections (such as MetaMask, Phantom, WalletConnect, or Coinbase Wallet). We never have access to your private keys, seed phrases, or custodial exchange balances.

2. Information We Collect

We collect minimal, privacy-preserving technical information necessary to deliver and secure our services:

Browser & Device Telemetry: Standard HTTP request logs, browser user-agent, operating system, and IP address for DDoS mitigation and rate-limiting API security.
Client-Side Calculations: Profit/loss inputs, DCA schedules, and calculator parameters are processed client-side in your web browser and are not stored on our permanent databases.
Search Queries & On-Chain Addresses: When you look up a public Bitcoin address or 0x transaction hash, that query is forwarded to public blockchain RPCs to fetch state. We do not associate public addresses with your personal identity.

3. Advertising & Cookies

BlockToolsHub may display non-intrusive contextual display advertisements (such as Google AdSense). Third-party vendors, including Google, use cookies to serve ads based on prior visits to this or other websites. You may opt out of personalized advertising by visiting Google Ads Settings.

4. Affiliate Disclosures

Our website contains affiliate links to verified hardware wallet manufacturers (such as Trezor) and crypto tax software providers (such as CoinLedger). Clicking these outbound links may set tracking cookies governed by the respective third-party provider's privacy policy.

5. BlockToolsHub Pro Waitlist & Email Communications

When you voluntarily register for the BlockToolsHub Pro early access waitlist, we collect your email address, submission timestamp, referral source, and optional feature preferences. We use this information solely to notify you when early access cohorts open, and—if explicitly opted into—to send occasional research and product updates.

We never sell, rent, or trade subscriber contact lists. Your email is stored securely with rate limiting and bot protections. You may request immediate removal or deletion of your email from our waitlist at any time by contacting privacy@blocktoolshub.com or clicking the unsubscribe link in any communication.
