Privacy Policy

We collect only the information needed to provide and improve KineRuby.

• Account Data: When you register, we securely store your email address and authentication credentials via our database provider, Supabase.
• Research Data: If you are signed in, we store your watchlist, saved screens and custom peer groups so they sync across your devices. Recently viewed tickers stay on your device only.
• Payment Data: If you subscribe to Premium, payments are processed by Stripe. We never see or store your full card details; we store only your Stripe customer ID and your subscription status, plan and renewal date.
• Communication Data: If you contact us via our Contact Us form, we securely capture your message in our database.

We use your information strictly to operate our platform.

• Providing access to our research, charting, and valuation tools.
• Managing your account and, if you subscribe, your Premium subscription and billing.
• Syncing your saved research across your devices.
• Sending transactional emails, such as password resets and support replies, via our email provider, Resend.

We share your data only with essential third-party infrastructure providers to run our application:

• Supabase: For secure database hosting and user authentication.
• Stripe: For secure payment processing and subscription management if you subscribe to Premium.
• Vercel: For hosting our frontend web application.
• Resend: For routing support and transactional emails.

• Your account data is protected by row-level security, so each person can access only their own records.
• We keep your data while your account is active. To delete your account and associated data, contact us and we will process the request.
• Stripe retains payment records as required by financial regulations.

If you have questions about how we handle your data, please contact us at info@kineruby.com, or visit our Contact page.
