Effective Date: 6/23/2026
This Privacy Policy outlines the practices and procedures followed by Chartui ("we," "our," or "us") regarding the collection, use, storage, and disclosure of personal information obtained through the Stellar market data and charting interface ("Chartui"). We are committed to protecting the privacy of our users and ensuring compliance with the General Data Protection Regulation (GDPR) and other applicable data protection laws. By accessing or using the Website, you agree to the terms of this Privacy Policy.
We may collect personal information from you when you voluntarily provide it while using the Website. This may include but is not limited to your name, email address, contact details, and payment information.
We may collect non-personal information related to your use of the Website, such as your IP address, browser type, device information, operating system, and browsing behavior. This information is collected to improve our services, enhance the user experience, and ensure the security of the Website.
We may use the personal information you provide to facilitate and fulfill your subscriptions, process transactions, and provide customer support. This includes managing user accounts, verifying user identities, and communicating with you regarding your subscription and account-related matters.
We may use the information collected to analyze trends, track user activities, and gather demographic information to improve the functionality and performance of the Website. This helps us customize and enhance your user experience while using the Website.
With your consent, we may use your contact information to send you promotional materials, newsletters, and other marketing communications. You have the right to opt-out of receiving such communications at any time by following the instructions provided in the communication or contacting us directly.
We may process and disclose your personal information as required by applicable laws, regulations, or legal proceedings, including responding to lawful requests from public and government authorities.
We may share your personal information with trusted third-party service providers who assist us in operating the Website and delivering our services. These service providers are contractually bound to handle your information securely and only for the purposes specified by us.
In the event of a merger, acquisition, or sale of our company or its assets, your personal information may be transferred to the acquiring party as part of the transaction. We will notify you via email or prominent notice on the Website in case of any such change in ownership.
We may disclose your personal information if we believe it is necessary to comply with applicable laws, regulations, legal processes, or enforceable governmental requests. We may also disclose your information to protect our rights, privacy, safety, or property, as well as those of our users or the public.
We implement reasonable technical and organizational measures to protect your personal information from unauthorized access, loss, misuse, alteration, or destruction. However, no data transmission or storage system can guarantee absolute security. You are responsible for keeping your account login credentials confidential, and we recommend choosing a strong password and exercising caution when accessing the Website.
You have certain rights regarding your personal information, subject to applicable laws. This includes the right to access, correct, update, or delete your personal information. If you wish to exercise these rights or have any inquiries about your personal information, please contact us using the information provided at the end of this Privacy Policy.
We use strictly necessary cookies and browser storage to operate the Website (including keeping you signed in and storing your settings). For analytics we use Cloudflare Web Analytics, which is cookieless and collects no personal data, so no analytics cookies are placed and no consent banner is required. See our Cookie Policy for a detailed overview.
We process your personal information on the following legal bases under the GDPR: (a) performance of a contract, to provide the services you sign up for; (b) consent, for any marketing communications, which you may withdraw at any time; (c) legitimate interests, to secure, maintain and improve the Website — including privacy-friendly, cookieless analytics that does not collect personal data — provided these are not overridden by your rights; and (d) legal obligation, where we are required to process or retain information by law.
We retain personal information only for as long as necessary for the purposes set out in this Privacy Policy: account and subscription data for the life of your account and as required to meet legal, accounting or tax obligations after closure. Our analytics (Cloudflare Web Analytics) is cookieless and aggregate and does not retain information that identifies you. You can delete your account at any time, after which we remove or anonymize your personal data except where retention is legally required.
Some of our service providers (such as Cloudflare, which provides our cookieless Web Analytics) may process data outside the European Economic Area, including in the United States. Where this occurs, the transfer is safeguarded by an appropriate mechanism under the GDPR, such as the EU-U.S. Data Privacy Framework or the European Commission's Standard Contractual Clauses.
We use Cloudflare Web Analytics to understand how visitors use our Website on an aggregated basis (such as page views, referrers and country). It is cookieless, sets no cookies, does not use client-side storage, and does not collect personal data or track you across sites — so it requires no consent and there is nothing for you to opt out of.
If you believe our processing of your personal information infringes data protection law, you have the right to lodge a complaint with your local data protection supervisory authority.
This Website is currently operated as a personal, pre-release (alpha) project. If you have any questions about this Privacy Policy or wish to exercise your rights, you can reach us via our X account at https://x.com/chartuicom. Formal data controller contact details will be added here once an operating entity is established.
