Privacy Policy

Last updated: July 22, 2026

This Privacy Policy explains how Aphelion AI (“Aphelion”, “we”, “us”) collects, uses, and safeguards your information when you use our website and stock-analysis services (the “Service”). By using the Service you agree to the practices described here.

Information We Collect

We collect the following categories of information:

Account information — when you register, we collect your email address and authentication details. Accounts and sessions are managed through our authentication provider (Supabase).
Payment information — if you purchase a paid plan, payments are processed by our third-party processors (Stripe and PayPal). We do not store your full card number; it is handled directly by the processor. We retain limited billing metadata such as plan, status, and transaction identifiers.
Usage & device data — we collect analytics such as pages viewed, features used, approximate location, browser, and device type through analytics providers (PostHog and Google Analytics) to understand and improve the Service.
Content you provide — stocks you analyze, watchlists you create, and feedback you submit.

How We Use Your Information

To provide, maintain, and improve the Service and its AI analysis features.
To process payments, manage subscriptions, and prevent fraud.
To communicate with you about your account, updates, and support requests.
To analyze usage trends and measure and improve performance.
To comply with legal obligations and enforce our terms.

Cookies & Tracking

We use cookies and similar technologies for authentication, to remember preferences, and for analytics. You can control cookies through your browser settings; disabling them may affect some features of the Service.

How We Share Information

We do not sell your personal information. We share data only with service providers who help us operate the Service — including payment processors (Stripe, PayPal), analytics providers (PostHog, Google), and infrastructure/authentication providers (Supabase) — and only as needed to perform their functions. We may also disclose information when required by law or to protect our rights and users.

Data Retention

We retain personal information for as long as your account is active or as needed to provide the Service, comply with legal obligations, resolve disputes, and enforce agreements. When data is no longer required, we delete or anonymize it. You may request deletion of your account and associated data at any time.

Data Security

We use industry-standard safeguards — including encryption in transit (HTTPS), access controls, and reputable infrastructure providers — to protect your information. No method of transmission or storage is completely secure, however, and we cannot guarantee absolute security. If we become aware of a breach affecting your personal data, we will notify you and the relevant authorities as required by law.

International Data Transfers

Our providers may process and store data in countries other than your own. Where personal data is transferred across borders, we rely on appropriate safeguards (such as standard contractual clauses) and require our providers to protect it consistent with this policy.

Legal Bases for Processing (EEA/UK)

Where the GDPR applies, we process personal data on the following bases: performance of a contract (to provide the Service), our legitimate interests (to secure and improve the Service and prevent fraud), your consent (for optional analytics and marketing, which you may withdraw), and compliance with legal obligations.

Your Rights

Depending on your location, you may have rights to access, correct, export, or delete your personal data, and to object to or restrict certain processing (for example under the GDPR or CCPA). To exercise these rights, contact us at ryanyuan@gmail.com.

Children’s Privacy

The Service is not directed to individuals under 18, and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Last updated” date above and, where appropriate, by additional notice.
