GeoProofThis policy explains how the GeoProof Android app (“the app”, package
com.geoproof.fieldcamera) and this website handle information. The app is published by
Siva Prasad (“we”, “us”). If you have a question, write to
sivaprasad979@gmail.com.
- Your photos, locations, notes, projects and reports are stored only on your phone, in the app's private storage.
- We run no servers that receive your data. There is no account, no analytics, no advertising and no in-app purchases. The app is free.
- Location is used only while the app is on screen, never in the background.
- Data leaves your phone only when you share it, or when you turn on the optional address lookup.
- Stamped photos you share contain their GPS location by default. You can turn this off in Settings.
1. Information the app handles
The app creates and stores the following on your device. None of it is sent to us.
| Information | Why | Where it is kept |
|---|---|---|
| Photos you take or import | The core purpose of the app | App's private storage |
| Capture time, time zone and time source | To stamp and document when a photo was taken | On-device database |
| Location: latitude, longitude, accuracy, altitude, fix time, compass heading | To stamp and document where a photo was taken | On-device database; also inside stamped copies (see section 5) |
| Street addresses (only if you turn on address lookup) | To show a readable address on stamps and reports | On-device database and address cache |
| Notes, projects, site details, visits, inspection results, report settings, inspector and company names you type | To organise your work and build reports | On-device database |
| PDF reports and your logo (if you add one) | Report generation and branding | App's private storage |
| App settings | To remember your preferences | On-device preferences |
The app records a SHA-256 fingerprint of each original photo so you can check later that the file has not changed. The app does not collect contacts, call logs, microphone audio, advertising IDs or device identifiers.
2. Location
- The app asks for location permission so it can record where photos are taken. You can choose precise or approximate location. Approximate locations are clearly labelled.
- Location is read only while the camera screen, the Home screen's GPS status card or a “use current location” action is on screen. The app does not request background location and does not track you.
- You can refuse location access and still take photos. They are then marked “Location unavailable”. The app never invents or estimates coordinates.
- Compass heading comes from your phone's motion sensors and is labelled magnetic and uncalibrated.
3. Camera and photos
Camera permission is used only to take photos inside the app. The app does not record video or audio, and the microphone permission is removed from the app. To import an existing photo you pick it with Android's system photo picker, so the app can only see the photos you select. It reads their date and location metadata, which is labelled “unverified”.
4. Optional address lookup
Address lookup is off by default. If you turn it on, the coordinates of your photos are sent to your phone's built-in geocoding service to get a street address. On most Android phones this service is provided by Google, and Google's privacy policy applies to that request. GeoProof does not send your photos. Results are cached on your phone so nearby photos don't need another lookup. You can turn this off at any time in Settings.
5. When data leaves your phone
Your data leaves your phone only in these cases, all started by you:
- Sharing photos or PDF reports through Android's share sheet (for example to WhatsApp or email). The receiving app or person gets the file, and their own privacy terms apply.
- Address lookup, if you turn it on (section 4).
We do not sell, rent or trade your information. We never receive it in the first place.
6. Storage, backup and deletion
- All app data is kept in the app's private storage, which other apps cannot read.
- Android cloud backup and device-to-device transfer are turned off for GeoProof data, so your photos and locations are not copied to your Google account. This also means the app cannot restore them for you. Share or copy anything you need to keep before you change or reset your phone.
- Data is kept until you delete it. Deleting a photo, project or report in the app removes its files. Uninstalling the app permanently deletes all GeoProof data on the phone.
- Because we hold none of your data, we cannot recover or delete anything for you remotely.
7. Security
Your data is protected by Android's app sandbox and your phone's own encryption and screen lock. Anyone who can unlock your phone and open the app can see your photos, so use a screen lock. Files are shared through temporary content links, never through private file paths. No method of storage is perfectly secure, but keeping data on your device and off any server limits who can reach it.
8. Android permissions
| Permission | Used for |
|---|---|
| Camera | Taking photos in the app |
| Precise and approximate location | Recording where photos are taken, while the app is on screen |
The app does not request internet, storage, microphone, contacts or background location permissions. The optional address lookup is carried out by Android's own geocoding service, not by GeoProof.
9. Children
GeoProof is a work tool intended for adults. It is not directed to children under 13 (or the equivalent minimum age where you live), and we do not knowingly collect information from children. In any case, the app does not send personal information to us.
10. Your choices and rights
You control your data directly in the app. You can view, edit, share or delete any photo, project or report, turn address lookup and GPS-in-EXIF on or off, and revoke camera or location permission in Android settings at any time. Depending on where you live, including under India's Digital Personal Data Protection Act, 2023, and the EU GDPR, you may have rights to access, correct or erase personal data. Because we do not hold your data, you can exercise those rights in the app itself. For any request or concern, contact us and we will reply within 30 days.
11. This website
This website is hosted on GitHub Pages. It uses no cookies, analytics, advertising or third-party fonts or scripts. Like any web host, GitHub may log technical data such as your IP address to operate and secure its service. See the GitHub Privacy Statement.
12. Changes to this policy
If the app's handling of data changes, we will update this page and its effective date before the change is released, and note significant changes below. If a future version adds anything that sends your data off the device, it will be optional and will ask for your consent first.
| Version | Date | Changes |
|---|---|---|
| 1.0 | 28 Oct 2026 | First published. |
| 1.1 | 29 Oct 2026 | GeoProof is now completely free: in-app subscriptions and Google Play Billing were removed. New package name. The app no longer requests the internet permission. |
