FieldSolve
FieldSolve contains no analytics framework, no crash- or performance-reporting SDK, no advertising SDK, and no social-media SDK. It does not request the iOS advertising identifier and does not ask for App Tracking Transparency permission, because it does not track you across apps or websites.
We — the developer — receive no data from your use of the app. We cannot see your rifle profiles, your loads, your shot data, your locations, or how often you open the app. We operate no server that the app talks to.
FieldSolve is a working tool, so it saves your setup locally so it is there next time. This includes:
This data lives in your device's private app storage. It is not readable by other apps, and it is not transmitted to us or to anyone else. It is included in your device backup (iCloud or Android backup) only according to your own device backup settings, which are governed by Apple's or Google's privacy policy rather than ours.
FieldSolve makes network requests only for the features below, and only when that feature is in use. No account identifier, device identifier, advertising ID, or profile data is attached to any of these requests.
| Service | What is sent | Why |
|---|---|---|
Open-Meteoapi.open-meteo.com |
Your latitude and longitude, when you use the automatic atmosphere feature. Coordinates along your line of sight, when the Field tab needs terrain elevation. | To return the current temperature, station pressure, and relative humidity at your position — the inputs a firing solution needs — and terrain elevation for ranging. |
Esri ArcGISserver.arcgisonline.com |
Standard map-tile requests (tile coordinates) while the Field tab map is on screen. These reveal the map area you are viewing. | To draw the satellite and topographic map used for GPS field ranging. |
| fxchrony.com | Nothing from the app. A tap opens the page in your normal browser, which then behaves like any other website visit. | Only when you deliberately tap a link to the FX Chrony site. |
Open-Meteo and Esri are independent companies and are not operated by us. Like any web service, they may log the IP address that a request comes from; we have no access to those logs. Their handling of that data is covered by their own policies: Open-Meteo terms and privacy and Esri privacy statement.
If you never turn on automatic atmosphere and never open the map, FieldSolve makes no internet requests at all. The solver itself is fully offline — every ballistic calculation runs on your device.
FieldSolve talks to measuring equipment directly, without going through the internet:
192.168.4.1). Images and settings pass between your phone and that camera only. Nothing is routed to the internet or to us.Android requires location permission in order to scan for Bluetooth devices on some versions of the operating system. Where that is the case, the permission is used for the scan and nothing more.
| Permission | Used for |
|---|---|
| Bluetooth | Finding and connecting to your wind meter or chronograph. |
| Location (precise / approximate) | GPS ranging on the Field tab, and fetching the atmospheric conditions at your position. On Android, also required by the system for Bluetooth scanning. |
| Camera | Recording a video of your shot with the live firing solution overlaid. |
| Microphone | Capturing the sound of the shot on that video. |
| Photo library (add) | Saving a video you chose to export into your photo library. |
| Local network (iOS) | Connecting to a target camera on your Wi-Fi. |
Every one of these is used only for the stated feature, only while you are using it, and never for advertising or profiling. You can decline or later revoke any of them in your device settings; the affected feature simply stops working, and the rest of the app carries on.
Videos you record are written to FieldSolve's private storage on your device. They are uploaded nowhere. Two things move them, and both require an explicit action from you: exporting a clip saves it to your photo library, and sharing a clip hands it to your device's standard share sheet, where you pick the destination. Once you share a file with another app or service, that recipient's privacy policy governs what happens next.
FieldSolve can accept a load handed over from a companion app — for example the Handload reloading log — through a link of the form fieldsolve://dope?…. The bullet and rifle details in that link are passed between the two apps on your own device and are used to build a profile and a range card. Nothing about the handover is transmitted off the device or reported to us.
FieldSolve is a technical tool for adult shooters, hunters, and competitors. It is not directed at children, and it is not designed for or marketed to children under 13. We do not knowingly collect information from anyone — including children — because, as described above, we do not collect information at all.
Because your data is held only on your device, you are in full control of it. Profiles, loads, and videos can be deleted inside the app. Deleting FieldSolve removes all of its stored data from the device. There is no copy of it on our side to request, correct, export, or erase — we do not have one.
Privacy laws including the EU and UK GDPR and the California Consumer Privacy Act give you rights of access, correction, deletion, portability, and objection over personal data a company holds about you. We hold none: FieldSolve creates no user account and transmits no personal data to us, so there is no record for us to disclose, amend, or delete. We do not sell or share personal information, and we do not engage in targeted advertising. Where a request of yours concerns the third-party services in section 3, it should be directed to that provider.
Your data is protected primarily by your device: FieldSolve's storage is sandboxed by iOS and Android, and it inherits your device passcode and disk encryption. Requests to Open-Meteo and Esri use HTTPS. Communication with a local target camera and with Bluetooth equipment stays on your own network or radio link, and is unencrypted because that is how the hardware works — treat it as you would any local device on your Wi-Fi.
If the app's data practices change, this page will be updated and the effective date at the top will change with it. Material changes — for instance the addition of any new outside service — will be described here rather than made quietly.
