1. Information We Collect

1.1 Information You Provide Directly

We do not require account registration to use any tool on CryptoCalcHub. The only personal information we collect is what you voluntarily submit through our contact form: your name and email address. This information is used solely to respond to your enquiry.

1.2 Calculator Inputs

All calculator inputs (investment amounts, prices, hashrates, etc.) are processed entirely within your browser. These values are never transmitted to or stored on our servers.

1.3 Automatically Collected Information

When you visit our website, our server and analytics tools automatically collect certain technical information, including your anonymised IP address, browser type and version, operating system, referring URL, pages visited, time and date of visit, and time spent on each page. This data does not identify you personally.

1.4 Cookies and Similar Technologies

We use cookies and similar browser storage technologies for the following purposes:

Functional cookies: We store your chosen light or dark theme preference in localStorage so your preference is remembered between visits. No personal data is involved.
Analytics cookies: Google Analytics 4 places cookies to collect anonymised usage statistics (pages visited, session duration, traffic source). IP addresses are anonymised before storage. You can opt out via Google Analytics Opt-out.
Advertising cookies: Google AdSense places cookies to display relevant advertisements. These cookies may collect data about your browsing behaviour across websites to personalise ads. You can manage ad personalisation at Google Ad Settings.
Affiliate tracking cookies: When you click an affiliate link to a third-party platform (such as a cryptocurrency exchange or wallet provider), that platform may set its own tracking cookies. These are governed by the third party's privacy policy, not ours.

To operate and improve our website, tools, and content.
To respond to enquiries submitted via our contact form.
To analyse site usage and understand how visitors interact with our tools.
To serve relevant advertisements through Google AdSense.
To comply with applicable legal obligations.

We do not sell, rent, or trade your personal information to any third party. We do not use your data for automated decision-making or profiling.

3. Google AdSense and Third-Party Advertising

We participate in the Google AdSense programme. Google AdSense uses cookies and web beacons to serve advertisements based on your prior visits to our website and other websites across the internet. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and other sites on the internet.

You may opt out of personalised advertising at any time by visiting Google Ad Settings. Alternatively, you can opt out of third-party vendor use of cookies for personalised advertising by visiting www.aboutads.info/choices (USA) or www.youronlinechoices.eu (EU/UK).

4. Affiliate Links

CryptoCalcHub contains affiliate links. These are clearly identified where possible. If you click an affiliate link and complete a qualifying action (such as registering an account or making a purchase), we may earn a commission at no additional cost to you.

Current affiliate partners include but are not limited to Coinbase, Binance, Ledger, Kraken, NiceHash, Koinly, and Amazon Associates (for book recommendations). Each partner has their own privacy policy governing the data they collect when you visit their sites.

6. Data Retention

Anonymised page-view analytics are retained for up to 24 months before automatic deletion. Contact form submissions are retained for up to 6 months to allow follow-up, then permanently deleted. Server-side cryptocurrency price cache data is automatically purged every 5 minutes.
