Privacy Policy

1. Information we collect

We collect information you provide when creating and using an ATI account, including your name, email address, password hash, display and account settings, Watchlist symbols, Portfolio positions, purchase prices and quantities, subscription or trial status, and messages you send to us.

We also use essential session-cookie and technical information required to keep you signed in, secure the service and diagnose errors. ATI does not currently use advertising or analytics cookies.

2. Why we use your information

• To create your account and provide ATI — necessary to perform our contract with you.
• To authenticate users, prevent misuse, maintain security and improve reliability — our legitimate interests in operating a safe service.
• To manage trials, subscriptions, limits and support — performance of our contract and legitimate interests.
• To meet tax, accounting, legal or regulatory obligations where applicable — compliance with legal obligations.

If we introduce optional marketing emails, we will request any consent required by law and provide an unsubscribe option.

3. Market data and service providers

ATI obtains market data through third-party tools, currently including Yahoo Finance data accessed through the yfinance software library. Instrument symbols may be sent to those services to retrieve market information. Railway provides application hosting and primary storage, Cloudflare R2 stores encrypted off-platform service backups, Cloudflare Turnstile processes limited browser and challenge information to help distinguish people from automated abuse on account forms, Stripe processes subscription checkout and billing information, Sentry processes limited technical error information used to diagnose faults, and Resend processes email addresses and transactional email content for account verification and password recovery. These providers process information under their own terms and applicable data-protection arrangements.

We do not sell your personal information. We disclose information only when needed to operate ATI, comply with law, protect rights and security, or complete a business transfer subject to appropriate safeguards.

4. International transfers

Some providers may process information outside the United Kingdom. Where UK data-protection law requires it, we use an adequacy regulation or appropriate contractual safeguards and assess the protection available.

5. How long we keep information

We keep account information while your account exists and for as long as reasonably needed afterwards for security, dispute resolution, legal, tax and accounting purposes. Watchlist, Portfolio and settings data currently remain stored if a trial or subscription expires so they are available if access is restored.

You may request account deletion by email. We may retain limited records when legally required or necessary to establish, exercise or defend legal claims.

6. Security

ATI uses measures designed to protect information, including hashed passwords, restricted account access, security settings for session cookies, email verification, single-use password recovery links and encrypted off-platform backups. No internet service can guarantee absolute security. You are responsible for keeping your password confidential.

7. Your UK data-protection rights

Depending on the circumstances, you may have rights to access, correct, erase or restrict your information, object to processing, receive portable data, and withdraw consent where consent is the legal basis. Legal exceptions may apply.

Send requests to useatiinfo@gmail.com. You may also complain to the UK Information Commissioner’s Office at ico.org.uk.

8. Children

ATI is intended for adults aged 18 or over. We do not knowingly offer accounts to children.

9. Changes

We may update this policy as ATI, its providers or legal requirements change. We will change the date above and provide additional notice when a material change requires it.
