Overview
RookieKit (rookiekit.app, “the Site”) is a collection of web tools for games, operated by Ullim. This privacy policy explains how the Site handles information.
No account; what you paste stays in your browser
The Site has no sign-up or sign-in. Item text you copy from a game and paste, and numbers you enter, are read only inside your browser and saved in your browser’s storage (localStorage) so you can pick up where you left off. They are never sent to a server. The Site saves:
- Gear Check: your build, main defence and level, and the item text you registered as equipped — remove it with “Remove” in the equipped list
- Weapon DPS Calculator: the weapon numbers you entered, and the name and numbers of your reference weapon — remove it with “Clear reference”
- Resistance Checker: the resistances and cap you entered, and the item text you pasted — remove it with “Clear”
- Increased vs Added Damage Calculator: the numbers you entered To delete everything at once, clear this site’s data in your browser settings.
Hosting (Cloudflare)
The Site is served by Cloudflare Pages (Cloudflare, Inc.). When you open a page, ordinary connection information such as your IP address, browser and device details and the requested address is sent to Cloudflare, used to deliver and secure the Site (blocking attacks), and kept under Cloudflare’s policies.
Site analytics (Google Analytics)
To improve the tools, we use Google Analytics to collect pages viewed, scrolling and outbound link clicks, events such as which tool you pasted an item into and whether it was read, the kind of result shown, the type of item you registered as equipped (for example, gloves), saving a reference weapon and moving between tools, along with browser and device type, country and approximate location inferred from IP address, and a cookie identifier created for each browser. The item text you paste and item names are never sent. We do not receive information that tells us who you are, such as your name or contact details, and this data is kept for 14 months. In the EEA, the UK and Switzerland, it is collected only if you allow it in the consent prompt.
Advertising (Google AdSense)
The Site is supported by Google AdSense ads. Google and its partners use cookies and similar technologies to show ads based on your visits to this and other sites and to measure ad performance. You can turn off personalized ads in Google’s Ad Settings (adssettings.google.com). In the EEA, the UK and Switzerland, your choice in the consent prompt applies; if you do not consent, you see non-personalized ads. Even with non-personalized ads, approximate location may be used to show locally relevant ads and to prevent fraud. To learn how Google uses information, see policies.google.com/technologies/partner-sites.
Cookies
The Site uses cookies from Google Analytics and Google AdSense. You can block or delete cookies in your browser settings, and the tools work the same if you do. In the EEA, the UK and Switzerland, you can change your consent choice at any time with “Privacy choices” at the bottom of the page.
International transfers
Google LLC (United States): Google Analytics and AdSense. Cloudflare, Inc. (United States): hosting and security. Data is sent over the network when you open the Site and kept as described above. Transfers from the EEA, the UK and Switzerland to the United States rely on the safeguards each company uses, such as the EU-U.S. Data Privacy Framework or Standard Contractual Clauses.
Legal basis (EEA, UK, Switzerland)
Site analytics and personalized ads are based on your consent; hosting and security on our legitimate interest in providing a stable Site.
Your rights
With no account, the Site cannot identify you. You can delete what is saved in your browser as described above. To request access, deletion or restriction of analytics data, or to object, contact us below. If you are in the EEA, the UK or Switzerland, you may lodge a complaint with your local supervisory authority.
Children
The Site is not directed to children and does not knowingly collect children’s personal information.
Changes
If this privacy policy changes, we will post the update on this page.
