A clear explanation of what the site may collect
Bitcoindu does not require an account. This page explains analytics, external services and how contact messages are handled.
Use the site without creating a profile or sharing wallet credentials.
Basic technical and analytics data may still be processed when pages load. External services have their own terms and privacy controls.
Traffic measurement
Bitcoindu uses Google Analytics to understand aggregate visits and page use. The service may process browser, device, approximate location and interaction information under its own policies.
Calculator services
Calculator pages may request public market data from CoinGecko. Those requests can expose standard technical information such as an IP address and browser headers to the provider.
Links and explorers
Links to blockchain explorers, documentation and other websites take you to services controlled by third parties. Their privacy practices apply after you leave Bitcoindu.
Public donation messages
When you claim an eligible Bitcoin donation, Bitcoindu stores and publicly displays the transaction hash, donation amount, publication time and the message you submit. The transaction hash and amount are already public on the Bitcoin blockchain. Do not place personal data, secrets or sensitive information in the message.
Messages you send
Email sent to bitcoin@bitcoindu.com is used to read and respond to the message, keep necessary records and address abuse, security or correction reports.
Information we never request
Do not send seed phrases, private keys, passwords, identity documents or exchange credentials. Bitcoindu cannot use them safely and will never request them by email.
Privacy contact
Questions about this page or a message you previously sent can be directed to the project email. Include enough context to identify the relevant communication.
Questions about data use?
Contact the project directly. Do not include wallet secrets or account credentials.
