Privacy Policy

Information collected

cryptorainbowcharts.com is a static research site. The site does not require users to create an account or submit personal information to view charts.

If you submit the weekly update form, the site collects the email address you enter plus form metadata such as the signup source and page value. If you contact the site by email, the information you provide may be used to respond to your request.

Email signup processing

Weekly update signups are submitted to a Google Apps Script web app and stored in a Google Sheet controlled by the site maintainer.

Google may process this information according to Google terms and privacy policies. Do not submit the signup form if you do not want your email address processed by Google services.

Newsletter email addresses are used to send crypto rainbow chart updates, market snapshots, and related site announcements. The signup form is not for financial advice, account access, or paid services.

Analytics and advertising

The site may use analytics, advertising, affiliate, or sponsored content technologies. These services may use cookies, device identifiers, IP addresses, or similar signals according to their own policies.

Third-party ad or analytics providers may process information independently. Review your browser privacy settings if you want to limit cookies or tracking technologies.

Data security and retention

Reasonable care is used when maintaining the site, but no website can guarantee absolute security.

Newsletter email addresses may be retained in Google Sheets until unsubscribe or removal is requested. Contact emails may be retained as needed to respond to requests, maintain records, or address abuse and policy issues.

To request removal from the weekly update list, contact cryptorainbowcharts@proton.me from the subscribed email address or use any unsubscribe instructions included in future emails.
