Privacy Policy

This policy explains how 4dan (https://4dan.app, “the site”) handles data when you browse it.

The site requires no sign-up and has no forms; we don't actively collect your name, phone number or other personal data. When you write to [email protected] we only use your email address and message to reply.

The site is hosted on Cloudflare, which processes connection data such as IP addresses for security and service operation; see Cloudflare Privacy Policy.

The site uses your browser's localStorage to remember your language and dark/light mode choice. This data stays on your device and is never sent back to our servers.

• The site may show ads in the future through third-party ad services such as Google AdSense.
• Once enabled, third-party vendors such as Google may use cookies to show ads based on your visits to this site and other sites on the web.
• You can go to Google Ads Settings to turn off personalized ads, or go to www.aboutads.info to opt out of third-party vendors' personalized ad cookies.
• For how Google uses data, see How Google uses data on partner sites.

Some pages embed TradingView charts and link to external sites such as exchanges (some are referral links). Those sites have their own privacy policies, which this policy doesn't cover.

This policy may be updated as the service changes; updates will be posted on this page. For any questions, write to [email protected].
