Supercell Disclaimer: ClashOS is an independent fan-created website and is not affiliated with, endorsed by, sponsored by, or approved by Supercell Oy.

1. Information We Collect

At ClashOS, we prioritize your privacy and minimize data collection. The primary piece of information you provide is your Clash of Clans player tag, which is entered voluntarily to use the tracker. We do not require account creation, and therefore we collect no passwords, names, or payment data.

When you browse ClashOS, we automatically collect basic usage data such as the pages you visit, the time spent on the site, and the features you interact with. This is gathered alongside standard technical information like your IP address, browser type, and device type to ensure our site functions properly across all platforms.

Additionally, we utilize cookies through third-party services like Google Analytics and Google AdSense. These cookies track interactions to provide insights into site traffic and deliver tailored advertisements. The player data fetched from the official Clash of Clans API using your tag is processed temporarily to display your progress and is not stored permanently on our servers.

2. How We Use Your Information

The player tag you provide is exclusively used to securely fetch your village and war data from the official Supercell Clash of Clans API. This data is rendered in your browser to power features like the Progress Intel, War Planner, and CWL Medal Calculator.

We use anonymous usage data collected via Google Analytics to understand which guides, tools, and resources are most valuable to players, helping us prioritize future content and feature updates. The data from advertising cookies is used to serve relevant ads through Google AdSense, ensuring that ClashOS can remain a free resource for all players without gating content behind paywalls.

We promise that we will never sell your personal data to third parties, data brokers, or marketing agencies. Since we don't collect emails for accounts, we will never use your data to contact you unsolicited.

3. Google AdSense and Advertising Cookies

ClashOS uses Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to ClashOS and other websites.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings at https://adssettings.google.com/ or by visiting www.aboutads.info to opt out of third-party vendor use of cookies for personalized advertising.

4. Cookie Consent

By using ClashOS, you consent to the use of cookies and similar technologies as described in this Privacy Policy. Where required by law, users will be presented with options to manage cookie preferences.

5. Third-Party Services

We integrate several essential third-party services to keep ClashOS running fast and secure. These services may process data as described in their respective privacy policies:

• Google Analytics: Used for tracking aggregated, anonymized usage data to understand traffic patterns. Google Analytics Privacy Policy.
• Google AdSense: Used for serving advertisements via cookies to support hosting costs. Google AdSense Privacy Policy.

6. Data Retention

Because ClashOS is an account-less tool, data retention is minimal by design:

• Session Data: Player tags and associated API data are stored locally in your browser to maintain your session. We do not store this data server-side.
• Lookup Logs: Player tag queries are not logged permanently in any database on our end.
• Analytics Data: Aggregated traffic data in Google Analytics is retained per Google's standard policy (currently 26 months).
• Cookies: Advertising and analytics cookies expire automatically according to the respective third-party service policies.

7. Your Rights (GDPR / CCPA)

We respect your rights regarding your data regardless of where you live. Since ClashOS does not require user accounts and stores minimal personal data, the scope of these rights may be limited. However, users may still contact us regarding any privacy concerns or requests at [email protected].

8. Children's Privacy

ClashOS is intended for users who are 13 years of age and older. We do not knowingly collect or solicit any personal information from children under the age of 13. If you are a parent or guardian and believe that a child under 13 has provided us with personal information, please contact us at [email protected] so we can promptly delete the information.
