Official Mod Telemetry
If you install or use the official Skill4ltu Mod, we may receive gameplay telemetry and battle-event data that the mod sends to our service. Depending on the feature used, this may include your Wargaming account ID, arena or battle identifiers, game and mod version, server or region information, timestamps, vehicle identifiers, shot and hit events, position and rotation data, battle performance metrics, and in-battle participant identifiers such as player names or clan tags as exposed by the game client.
We use this telemetry to provide battle analytics, detect active mod usage, improve the service, build and maintain aggregated gameplay datasets, develop reconstructed internal-module visualizations and related statistics, and help prevent abuse, fraud, and manipulation of our systems.
Some community analytics features may use reduced or outcome-only submissions rather than full battle telemetry, depending on the feature and the data needed for that specific service.

- Where relevant to supporter features, we may compare your YouTube channel information against our internal eligibility records to determine member-related access.
- If you disconnect your Google account or the cookies expire, the related access state is removed from active use. Clearing site data from your browser may also remove locally stored session preferences.

Wargaming Account Data Accessed
When you sign in with Wargaming, we process account data returned by Wargaming’s official authentication and account APIs, including your account ID, nickname, region, access token, token expiry, and confirmation that the token belongs to the account being linked.
We use this data to sign you in, associate your website features with your Wargaming account, support account-linked statistics and mod-related features, and determine whether your account appears active in recent mod telemetry.
If you use account-linked statistics pages and related tools, we may also request additional account data made available by Wargaming’s APIs, such as owned vehicles, tank statistics, achievements, marks, currencies, and other account information needed to display the features you requested.
Account-Linked Ratings and Contributions
If you submit vehicle ratings while signed in with Wargaming, we store the rating values you submit, the related tank ID, your Wargaming account ID, and associated timestamps. We use this data to show your own ratings back to you, calculate community averages, and operate rating-based features.

Official Mod Data
If you use the official Skill4ltu Mod, the mod may transmit gameplay and battle telemetry to our systems. We use this data to power analytics, account activity checks, feature development, and other service functionality described in this Privacy Policy. We do not treat the mod as a third-party script that runs on behalf of another controller; it is part of our own Service.
Service Providers
We use third-party providers to host, secure, analyze, monetize, and operate parts of the Service. Some of these third parties act on our behalf as service providers or infrastructure vendors. Others process data under their own terms when you choose to use their services through our website.
Examples include Directus for content management and certain stored records, Google Analytics for analytics, Wargaming for account-linked game data, Google/YouTube, Twitch, and Patreon for connected account verification, YouTube for media playback and linked content, Venatus and related advertising partners for ad delivery on ad-supported pages, and Google Forms when you choose to use our contact or bug-report forms.
Analytics
We may use third-party Service Providers to monitor and analyze the use of our Service.
Google Analytics: Google Analytics is a web analytics service offered by Google that tracks and reports website traffic. Google uses the data collected to track and monitor the use of our Service. This data is shared with other Google services. Google may use the collected data to contextualize and personalize the ads of its own advertising network.
You can opt-out of having made your activity on the Service available to Google Analytics by installing the Google Analytics opt-out browser add-on. The add-on prevents Google Analytics JavaScript (ga.js, analytics.js, and dc.js) from sharing information with Google Analytics about visits activity.
For more information on the privacy practices of Google, please visit the Google Privacy & Terms page.
Connected Platforms
We also rely on third-party platforms and APIs where you choose to use related features, including Wargaming for game account sign-in and account-linked data, Google/YouTube for subscription or membership checks, Twitch for follow and subscription checks, Patreon for patron status checks, YouTube for embedded video playback, and advertising providers such as Venatus for ad delivery on ad-supported pages.
Retention of Your Personal Data
We retain personal data we collect from you for as long as necessary for the purposes for which the personal data was collected or where we have an ongoing legitimate business need to do so (for example, to provide you with a product or service you have requested), or to comply with applicable legal, tax, or regulatory requirements.
When we have no ongoing legitimate business need to process your personal data, we will either securely destroy, erase, delete or anonymise it, or if this is not possible (for example, because your personal data has been stored in backup archives), then we will securely store your personal data and isolate it from any further processing until deletion is possible.
We will retain Your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy. We will retain and use Your Personal Data to the extent necessary to comply with our legal obligations (for example, if we are required to retain your data to comply with applicable laws or for other legitimate reasons like enforcement of legal rights, fraud prevention, etc.)
We will also retain Usage Data for internal analysis purposes. Usage Data is generally retained for a shorter period of time, except when this data is used to strengthen the security or to improve the functionality of Our Service, or We are legally obligated to retain this data for longer time periods.
Authentication and session cookies are generally retained only for their configured lifetimes. Account-linked ratings, analytics records, and telemetry-derived datasets may be retained for longer where needed to preserve historical analytics, operate features, prevent abuse, or protect legal rights.
Transfer of Your Personal Data
We do not sell your personal data. We may share limited personal data with service providers and platform partners where necessary to operate the Service, including analytics providers, content and data infrastructure providers, embedded media providers, advertising partners, form providers, and the account or membership platforms you choose to connect, such as Wargaming, Google/YouTube, Twitch, and Patreon.
Because these providers may operate internationally, your personal data may be processed in countries other than your own, subject to the policies and safeguards of the relevant provider and applicable law.
Your Rights
Depending on the law that applies, you may have a right to access and rectify or erase your personal data or receive a copy of your personal data, restrict or object to the active processing of your data, ask us to share (port) your personal information to another entity, withdraw any consent you provided to us to process your data, a right to lodge a complaint with a statutory authority and such other rights as may be relevant under applicable laws. To exercise these rights, you can write to us at business@skill4ltu.eu. We will respond to your request in accordance with applicable law.
Do note that if you do not allow us to collect or process the required personal information or withdraw the consent to process the same for the required purposes, you may not be able to access or use the services for which your information was sought.
Security of Your Personal Data
The security of your information is important to us and we will use reasonable security measures to prevent the loss, misuse, or unauthorized alteration of your information under our control.
However, remember that no method of transmission over the Internet, or method of electronic storage is 100% secure. Therefore, we cannot guarantee absolute security and consequently, we cannot ensure or warrant the security of any information you transmit to us and you do so at your own risk.
Links to Other Websites
Our Service may contain links to other websites that are not operated by Us. If You click on a third party link, You will be directed to that third party’s site. We strongly advise You to review the Privacy Policy of every site You visit.
