Privacy Policy
The most sensitive thing you give Trading AI is the chart you analyze. This page explains exactly what happens to it, what else we collect, why, who processes it and how to delete it.
Last updated: September 20261. Who we are
Trading AI ("the Service", "we", "us") is an iOS application operated by Alex Alonso. For any privacy question, contact us at alex28042@gmail.com.
This Privacy Policy describes how the Service collects, uses and shares personal information when you use the Trading AI mobile app or this website. It is written to comply with the GDPR, the CCPA and Apple's App Store privacy requirements.
2. What happens to the chart you analyze
The photo or screenshot you analyze is sent over an encrypted connection to our server, which passes it to an AI model to produce the verdict. The image is stored together with that analysis, linked to your account, so you can review it in your history; it is served back to you only through short-lived signed links. It is never used to train models, never shared with advertisers and never sold. Clearing your history or deleting your account removes the images from our servers.
3. Data we collect
- Account data: when you first open the app we create an anonymous session tied to a random user identifier. If you choose to link Sign in with Apple or Google, we additionally receive your email, optional name and a provider-scoped unique ID.
- Profile and questionnaire data: answers you give during onboarding about your trading experience, markets you trade and goals. Used solely to personalize the app.
- Analysis history: the chart image you submitted and the result of each analysis — verdict (buy / sell / hold), confidence score, detected signals, suggested levels and timestamps.
- Markets, alerts and journal: the markets you follow, the price alerts you set and the simulated trades you log, so they stay in sync across your devices.
- Usage quota: a counter of analyses used, to enforce the limits of your plan.
- Purchase data: your subscription status, current plan and purchase history, received from RevenueCat and Apple. We never see your payment card details.
- Push notification token: only if you allow notifications, a device identifier registered with OneSignal so we can deliver your price alerts.
- Usage data: which screens of the onboarding and paywall you reach, with app version and language, to understand where people drop off. OS version and anonymous diagnostics keep the app reliable.
4. How we use your data
- Provide the Service: run your analyses, keep your scan history in sync and personalize your experience.
- Process subscriptions: verify your entitlement through RevenueCat and unlock Pro features.
- Keep the Service reliable and secure: fix bugs, prevent abuse and enforce quotas.
- Communicate with you: answer support requests and send service-related notices.
We do not use your data for third-party advertising and we do not track you across other companies' apps or websites.
5. Legal bases (GDPR)
We rely on (i) your consent when you sign in with Apple or Google and voluntarily provide onboarding answers, (ii) contractual necessity to deliver the Service you subscribed to, and (iii) our legitimate interest in keeping the Service safe and improving it.
6. Who we share data with
- Our own API (hosted in the EU): stores your account, analysis history, markets, alerts and journal. Every request is resolved to your authenticated user and never reads another user's data.
- Anthropic: receives the chart image to produce the analysis, through the Claude API. It is not used to train their models.
- Apple: Sign in with Apple and App Store subscription processing.
- Google: only if you choose "Continue with Google" for authentication.
- RevenueCat: subscription management, entitlement checks and purchase restoration.
- OneSignal: delivery of push notifications (price alerts), only if you grant notification permission.
- Supabase (EU region): the backend of earlier versions of the app; it stays in service while those versions are still in use.
- Vercel: hosts this website and processes standard web server logs (IP address, user agent).
We never sell your personal data. No data broker, no ad network, no exceptions.
7. International transfers
Our primary database lives in the European Union. Some sub-processors listed above operate in the United States; transfers to them are protected by the European Commission's Standard Contractual Clauses.
8. Data retention
We keep your data for as long as your account is active. When you delete your account from Settings, your profile, onboarding answers, analysis history (including the chart images), alerts and journal are erased from our servers, and your contact is removed from the notification provider. Anonymous, aggregated metrics may be retained longer.
9. Your rights
Depending on where you live (GDPR, CCPA and similar laws), you have the right to access, correct, export, restrict or delete your personal data, and the right to object to certain processing. You can exercise the most important one — deletion — directly in the app: Settings → Account → Delete account. For anything else, email alex28042@gmail.com and we will respond within 30 days.
10. Children
Trading AI is not directed at children and is intended for users aged 18 or older. We do not knowingly collect personal information from children. If you believe a minor has provided us data, contact us and we will delete it.
11. Security
All traffic between the app and our backend is encrypted with TLS. Every request to our API is resolved to your authenticated user before any data is read or written, and chart images are only reachable through short-lived signed links. Payment data is handled exclusively by Apple and RevenueCat.
12. Changes to this policy
We may update this policy as the Service evolves. Material changes will be announced in the app or on this page, and the "Last updated" date above always reflects the current version.
