Privacy Policy & Cookie Disclosure
Last Updated: October 2026 | Effective Date: Immediately
At Ranomio (accessible from https://ranomio.com), the privacy and confidentiality of our visitors is our highest priority. This Privacy Policy document outlines how our zero-telemetry client-side architecture operates, what third-party services we utilize, and how advertising cookies and data are managed in compliance with Google AdSense program policies, GDPR, CCPA/CPRA, and LGPD.
1. 100% Client-Side Execution & Zero Telemetry
All randomization algorithms—including numbers, passwords, custom names, lottery picks, team rosters, bingo cards, and wheel slices—are computed locally inside your browser via the native Web Crypto API (SubtleCrypto CSPRNG). We do not store, record, transmit, or retain your custom inputs, names, passwords, or generated results on any server.
2. Google AdSense & Third-Party Advertising Policies
Ranomio uses Google AdSense and accredited third-party advertising vendors to display advertisements when you visit our website. These companies may use cookies and web beacons to collect anonymous information (not including your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.
- Google AdSense & DoubleClick DART Cookies: Google, as a third-party vendor, uses cookies to serve ads on Ranomio. Google's use of the DART cookie enables it and its partners to serve ads to users based on their visit to Ranomio and/or other sites on the Internet.
- Third-Party Vendors and Ad Networks: Third-party vendors or ad networks may also serve ads on Ranomio. These vendors use technology in their respective advertisements and links that appear on Ranomio, sent directly to your browser.
- Opting Out of Personalized Advertising: You may opt out of personalized advertising by visiting Google Ads Settings .
- Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info or Your Online Choices (EU) .
3. Cookies Classification & Consent Management
We classify cookies used across Ranomio into three transparent categories:
Required for core UI state, theme selection (dark/light), audio preferences, and offline PWA functionality.
Anonymous aggregated traffic measurement (Yandex Metrika) without collecting personally identifiable information.
Set by Google AdSense and certified partner networks to deliver contextual or personalized ads.
You can adjust or revoke your cookie choices at any time by clicking the link in our footer.
4. GDPR, CCPA/CPRA, & LGPD Compliance
Under global data privacy frameworks (including European Union GDPR, California Consumer Privacy Act CCPA/CPRA, and Brazilian LGPD), users possess rights regarding data access, rectification, erasure, and opt-outs.
Because Ranomio operates completely client-side without registration or personal user databases, we do not sell or monetize personal user information. Any cookie-based tracking by advertising partners complies with applicable opt-out frameworks.
5. Log Files & Edge Infrastructure
Like standard web infrastructure, our hosting environment (Cloudflare / edge CDN) maintains standard server logs for DDoS mitigation, load balancing, and network diagnostics. These logs capture anonymous connection headers and are not associated with personal user identities.
6. Children's Online Privacy Protection (COPPA)
Ranomio does not knowingly collect any Personal Identifiable Information from children under the age of 13. Our tools are general-purpose educational and utility generators suitable for all audiences.
