Privacy Policy
We are committed to protecting your privacy. We do not use tracking cookies. ChartBuff has no user accounts and does not sell personal information. We handle only the information needed to deliver, understand, and protect the service.

Information We Handle
When you use the site, the following information may be processed:
- request information needed to deliver and protect the service, such as the requested page or API path, time, and response status;
- search terms and interactions needed to return the page or result you requested;
- a coded value used instead of your IP address for request limits and abuse prevention.
- a Roblox Universe ID or experience link if you choose to request that a game be added.
We do not collect private platform profiles, ownership histories, account passwords, or payment information.
How We Use It
We use this information to deliver requested pages and data, secure the service, prevent abuse, diagnose failures, understand aggregate use, and comply with legal obligations. Where applicable, operational processing is based on our legitimate interests in providing and protecting the service. We use Umami to understand aggregate use.
We do not sell personal information.
Service Providers
Cloudflare processes traffic on our behalf to deliver, cache, and protect the site. Hosting and infrastructure providers process information only as needed to operate the service. Umami processes site-usage information on our behalf so we can understand aggregate use. Information may also be disclosed when required by law, to protect rights or safety, or as part of a business transfer subject to appropriate safeguards.
Some game artwork loads directly from Steam, Roblox, Epic Games, ppy, and CipSoft. These providers receive your IP address and other network information needed to deliver the images.
Cookies and Analytics
We do not use tracking cookies. Umami does not set cookies or store an analytics identifier in your browser.
Umami processes page views, site searches, referring pages, basic technical information, and approximate location. It groups activity into anonymous sessions without a persistent browser identifier and does not track you across websites.
We do not use analytics or advertising cookies. Cloudflare may use cookies or similar technology that is strictly necessary to provide security and network services.
The site temporarily caches public chart data in your browser's session storage to avoid repeating the same request. This cache is limited to the browser tab, is not a cookie, and is not used for analytics or to identify you.

Retention and Location
First-party operational data is stored in the United States. Cloudflare, Umami, and other providers may process information in additional countries under their own transfer safeguards. Umami operates in the United States and European Union. Under our current plan, analytics data is retained for up to six months.
Operational logs rotate under bounded storage limits, and temporary security and rate-limit records expire when they are no longer needed. Game-request records, including the submitted value and coded requester value, are scheduled for deletion 30 days after completion, or 30 days after submission if a request is still pending. Deleted records may remain in encrypted backups for up to 1 year while those backups expire. Legal or security obligations may require longer retention in a particular case.
Your Choices and Rights
Depending on where you live, you may have rights to access, correct, delete, restrict, or object to processing of personal information, to withdraw consent, or to appeal or complain to a privacy authority. Send a request using the contact below. We may need enough information to verify the request, and some rights are subject to legal exceptions.
Because we do not use tracking cookies, there is no analytics cookie preference to manage. You may still block the analytics script through your browser or privacy tools without losing access to the site.
Children
The service is not directed to children under 13, and we do not knowingly collect personal information from them. A parent or guardian who believes a child has provided personal information may contact us to request its deletion.
Changes
Material changes to this policy will be posted here with a revised date.
