Futures Helper · Privacy Policy
1. What we collect
No personal information. There is no account system, no sign-up, and no analytics, advertising, crash-reporting or third-party SDK.
Instrument names, prices, quantities, rates, units, colours and groups you enter stay on your device and are never visible to us.
2. When the app goes online
Only when you tap the get-price or get-rate button. The app then sends an instrument code (for example AG or XAU) or a currency pair (for example USDCNH) to this website public endpoint to fetch the corresponding reference price.
The request contains no personal data: no account, no device identifier, no location, and none of the prices you entered.
If you never tap those buttons, the app makes no network requests at all.
3. What the server logs
Like any website, the server keeps standard access logs (IP, time, path, User-Agent) for troubleshooting and abuse prevention, retained for no more than 30 days, never linked to an identity and never used for advertising or profiling.
Market data itself comes from public sources and is cached for five minutes to reduce request volume.
4. What happens to fetched values
A fetched price or rate is only used on your device for display and conversion, and is cached locally (no repeat request for five minutes).
The app always asks first — if you cancel, nothing you entered changes.
5. Where your data lives
Instruments, prices, rates, groups and settings are stored in the app sandbox and system preferences on your device. They never leave it.
Deleting the app deletes that data; we keep no backup and cannot restore it.
6. Third parties
We do not share, sell or transfer your information to anyone. The app contains no advertising or analytics SDK.
7. Children
The app does not collect information from children and contains no child-directed advertising or recommendations.
