Frequently asked questions
Does ArbiScan place trades?
No. It is a research scanner using public market data. It does not connect to your exchange account or ask for exchange API keys.
Is gross APR a guaranteed return?
No. It annualizes an observed spread before costs. It is not a return on deposited capital; fees, slippage, collateral requirements and changing rates affect outcomes.
Why are some opportunities or history missing?
Results depend on selected filters and available exchange data. Longer windows can have partial history. Check the scan timestamp and coverage notices, and try another scan window.
How do I restore a subscription?
Use the app’s Restore purchases action with the Apple Account used for the purchase. Deleting the app does not cancel a subscription; manage it through Apple’s subscription settings.
Can I change analytics and ad choices?
Use Settings → Privacy & terms for optional analytics and Settings → Ad privacy choices for regional ad consent. Tracking permission is controlled in iOS Settings.
Please do not email passwords, exchange API keys or payment-card details.
