We use collected data to operate the Service: authenticating you, delivering alerts, computing your portfolio/paper-trading performance, and improving the underlying models. We do not sell your personal data to third parties.
Account and application data is stored in our database. Sensitive values such as exchange API keys are encrypted at rest. You may request deletion of your account and associated data at any time.
SongTrade integrates with third-party data providers (Binance/ccxt, yfinance, vnstock) and, optionally, Telegram for alert delivery. These integrations are used solely to provide the features you enable and are governed by each provider's own privacy terms where applicable.
We use browser local storage to remember preferences such as your light/dark theme and language selection. We do not use third-party advertising trackers.
If you enable 2FA, we store a TOTP secret used solely to verify login codes. This is never shared with third parties.
We retain account data for as long as your account is active. Upon account deletion, personal data is removed within a reasonable period, except where retention is required for legal or fraud-prevention purposes.
You may access, correct, export, or request deletion of your personal data by contacting us via the contact page.
We may update this policy periodically. Material changes will be reflected by updating the "Last updated" date above.
