Privacy Policy

Last updated: 9 November 2026

This policy explains what personal data AlphaScreen ("we", "us") collects at app.quantplatfrom.trade, why, and your choices. We handle personal data in line with Singapore's Personal Data Protection Act 2012 (PDPA).

1. What we collect

• Account: your email address and a password stored only as a bcrypt hash. If you sign in with Google, we receive your Google account email and Google account ID.
• Your activity: your watchlist (tickers, date added, starting price) and any pool requests with the notes you write.
• Billing: your Stripe customer and subscription IDs and your subscription status. Card details are entered on Stripe's pages; we never see or store card numbers.
• Technical: IP address and request details in server logs, used for security and rate limiting. Your login token is kept in your browser's local storage. We do not use advertising or analytics cookies.

2. How we use it

To create and run your account, verify your email, give you the access you are entitled to, process payments, send service emails (email verification, password reset, payment problems, pool-request decisions and important changes to the service or these policies), protect the service from abuse, and meet legal obligations. We do not send marketing email without your consent.

3. Who we share it with

We do not sell your personal data. We share it only with providers that run the service for us:

• Stripe – payments and the billing portal.
• Google – Google sign-in (if you use it) and sending our emails through Gmail.
• Tencent Cloud – server hosting in Singapore, where our database is stored.

Company summaries, news sentiment and ticker logos are produced from public market data by AI and logo providers (Google Gemini, DeepSeek, logo.dev). They receive ticker symbols and public news only, never your personal data. We may also disclose data where the law requires it.

4. How long we keep it

We keep your data while your account exists. When you delete your account, your account, watchlist and pool requests are removed from our live database at once. Copies remain in database backups for up to about 14 days until they are rotated out. Stripe keeps its own payment records as required by law, under its privacy policy.

5. Security

Traffic is encrypted with HTTPS, passwords are hashed with bcrypt, and changing your password signs out existing sessions. No system is completely secure; tell us at once if you think your account has been misused.

6. Your choices and rights

You can see and change your watchlist in the app, and delete your account at any time from the Account section. You can also ask us for access to or correction of your personal data, or withdraw consent (which may mean closing your account), by emailing us. We will reply within 30 days.

7. International transfers

Our providers may process data outside Singapore. Where they do, we rely on their contractual commitments to protect it to a standard comparable to the PDPA.

8. Children

The service is not intended for anyone under 18, and we do not knowingly collect their data.

9. Changes

We may update this policy and will email subscribers about material changes before they take effect. The date at the top shows the latest version.
