ChartAI is a chart-analysis and trading-journal app provided by Sukhtumur Narantuya ("we", "us"). This policy explains how the mobile app handles your information. AI features require online processing; your journal is stored on your device, not automatically synced as a cloud journal.1. Charts, Analysis and AI Chat
When you request an analysis, selected chart images and timeframes are sent to our backend, then to OpenRouter and the AI model provider handling the request. Follow-up chat sends your question, relevant analysis context and, when included, chart images. Trends sends your chosen instruments and timeframe; our backend obtains market data and sends it to the AI provider for analysis.Only capture or select images you are allowed to use. Remove account names, balances and other private details before uploading, and do not put sensitive personal information in chat. We do not sell your chart images. Processing and retention by AI providers are governed by their policies and our service configuration; we do not promise zero retention or that every provider has identical training rules.2. App Identity and Service Records
ChartAI creates an anonymous authentication identity without requiring you to enter a name or email. Anonymous does not mean untraceable: the identity and session credentials let us verify access, associate purchases, enforce the free-analysis allowance and request limits, prevent abuse, and recover interrupted analyses.Our backend keeps identifiers, usage counters, request status, an input fingerprint and completed analysis responses for recovery. Hosting and service providers may process IP addresses, timestamps and technical logs. Our operational metrics cover failures, request timing and model usage/cost. We do not request precise device location.3. Journal, Backups and Diagnostics
Saved chart images, reports, journal entries, trade outcomes, fees and P&L are stored locally. A selected report or image may be sent again when you use AI chat. Deleting local history does not automatically delete backend recovery or purchase records.Backups can include journal records and chart images. You choose where to save or share them; exported files are not encrypted by ChartAI. Your device or cloud-backup provider may also back up app data under your device settings. Protect these files and remove unwanted copies yourself.The app keeps limited diagnostic events locally. You can share or clear these in Settings. These diagnostic records exclude chart images, chat text, journal notes, authentication tokens and trading prices. If you contact support or choose to share a report, backup or diagnostics, we receive only what you send.4. Permissions and Reminders
Camera and photo access let you capture, choose or save images. Notifications are optional local journal reminders and may show an instrument name on your lock screen. You can change permissions and notification visibility in your device settings.5. Subscriptions and Payments
ChartAI Pro is optional. Apple or Google Play processes purchases on supported platforms; we do not receive your payment-card details. RevenueCat processes app identifiers, purchase receipts or tokens, subscription status and relevant device information to manage and restore access. Subscription records may be linked to your anonymous app identity.6. Service Providers and Sharing
- Supabase: authentication, backend processing, recovery and usage records.
- OpenRouter and its AI model providers: processing images, questions and analysis context.
- RevenueCat: subscription verification and purchase restoration.
- Apple and Google: store billing and platform services, where applicable.
- Yahoo Finance and Binance: market prices, candles and news requested by our backend for the instruments you select.
We may also disclose information where required by law, to protect people and our rights, or to investigate fraud or security incidents. Providers may process information outside your country. Their own policies apply to their services.7. Retention and Your Choices
Your local journal remains until you delete it or remove the app's data. Uninstalling does not remove exported files, device/cloud backups, subscription records or all server records, and it does not cancel a subscription.Backend recovery records become eligible for cleanup seven days after completion or failure. Cleanup runs during later request processing, so records may remain longer; this is not an automatic deletion deadline. Raw uploaded chart images are not stored in that recovery table. Identity, quota, purchase and security records are retained as needed to operate the service, prevent abuse and meet legal obligations. Providers may retain their own records under their policies.To request access, correction or deletion of information we hold, or exercise other rights available where you live, email haruschatten@gmail.com. We may need information to locate and verify your anonymous app record. Do not send passwords, session tokens or payment-card details. Some records may need to be retained where permitted or required by law.8. Children and Security
ChartAI is not directed to children under 13, and we do not knowingly collect their personal information. Where a higher age or parental permission is required, that requirement applies. Contact us if you believe a child has provided personal information.We use HTTPS for backend communications and platform-protected storage for app session credentials. No system is completely secure. Keep your device and exported backups protected.9. Changes and Contact
We will update this page and its date when this policy changes, and provide additional notice or obtain consent where required. For privacy questions, contact Sukhtumur Narantuya at haruschatten@gmail.com.See also the ChartAI Terms of Use.
