This policy describes how CeylonQuant ("we", "us") handles personal information when you use our CSE research and screening product.
Account data you provide (such as email and profile details) is stored with our authentication provider. Usage of watchlists, portfolios, strategies, and alerts is stored in our application database and tied to your account.
We collect standard technical logs (IP address, browser type, timestamps) for security, abuse prevention, and reliability. Payment-related data is processed by our payment partner when you subscribe; we do not store full card numbers on our servers.
We use your information to operate the service, personalize your lists and alerts, communicate about your account, and improve product quality. Market data shown in the app is aggregated exchange and third-party data — not personal information about you.
With your consent where required, we may send transactional email (for example alert confirmations or security notices) through our email provider.
We share data only with subprocessors that help us run the product (hosting, database, email, payments) under contractual safeguards. We do not sell your personal information.
We retain account and usage data while your account is active. You can permanently delete your account from Account settings; that removes personal app data and your login identity. Limited operational logs may be kept for a short period for security and billing dispute resolution, as described in our retention configuration.
You can update account details or delete your account from Account settings. Alert rules can be paused or removed from the Alerts hub. Signing up again with the same email after deletion starts a new, independent account. This policy may be updated; material changes will be reflected on this page.
