Privacy Policy, Terms of Use and Disclaimer
App name: Landloop ("the App") Developer: Optical Spark ("we", "us", "our") Contact email: physics.optical.spark@gmail.com Effective date: 11 November 2026 Last updated: 11 November 2026
PART 1 – PRIVACY POLICY
1. Summary
- We do not require you to create an account.
- We do not collect, store, sell or share your personal information on any server owned by us. We do not operate a backend server for the App.
- The points you mark on the map and the areas you calculate stay on your device and are not saved after you close the App.
- Your display and converter preferences are remembered locally on your device and never leave it.
- The App contains no advertising, no analytics and no tracking tools.
- To show maps and find places, the App connects directly to two third-party services (see section 4). Those services receive limited technical data as described below.
2. Information we collect
We do not collect any personal data. In particular, the App does not collect your name, email address, phone number, contacts, photos, files, device identifiers, advertising ID, or usage statistics. Your device location is used only on your device to centre the map (see section 3) and is not collected by us.
3. Information processed on your device
The App processes the following only locally on your device, to provide its features:
- Map points (corners) you tap to measure an area, and the resulting area, perimeter and unit conversions. These are held in memory only and are deleted when you close the App or press Clear.
-
Preferences – your chosen area unit, converter unit/region selections, map detail level, label setting and whether you have seen the intro – are saved in the App's private local storage on your device so they are remembered next time. This data is never sent to us or anyone else and is removed when you clear the App's data or uninstall it.
- Reports – when you tap Report, the App creates a PDF on your device from the points you marked and lets you save it to a location you choose in the system save dialog, then opens it in your device's PDF viewer (using a temporary copy in the App's private cache). The report is never sent to us.
-
Device location – with your permission, the App reads your device location when it opens and when you tap the My location button, only to centre the map on where you are and show a blue dot. Your location is processed on your device, is not stored, and is not sent to us. You can deny or revoke this permission at any time in Android settings; the App still works and you can search for any place.
Because map images are loaded from Esri for the area you are viewing, Esri receives the tile coordinates of that area, which can reveal the general area you are looking at (see section 4).
The App does not use your camera, microphone or contacts, and it does not read your files; it only writes a report where you choose to save it. Android permissions used: INTERNET, ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.
4. Third-party services the App connects to
When you use the App, your device communicates directly with the services below. We do not receive or control the data they receive. Like any internet request, these requests necessarily include your device's IP address and basic technical details such as device/app user-agent information.
| Service | Purpose | Data sent to the service |
|---|---|---|
| Esri ArcGIS Online (World Imagery and Reference map tiles) | Displays satellite imagery and place labels | The map tile coordinates for the area you are viewing, IP address, user agent |
| OpenStreetMap Nominatim (operated by the OpenStreetMap Foundation) | Searches for a place when you type a name/address and press search | The text you typed in the search box, IP address, user agent |
| Google image servers (googleusercontent.com) | Shows app icons and a profile photo on the Developer page | Requested only when you open that page: your IP address, user agent |
Please review their privacy policies:
- Esri: https://www.esri.com/en-us/privacy/overview
- OpenStreetMap Foundation: https://osmfoundation.org/wiki/Privacy_Policy
- Google: https://policies.google.com/privacy
Links on the Developer page (Google Play and social networks) open in your browser or the relevant app and are then governed by those services' own policies.
Note: Text you type into the place-search box is sent to Nominatim. Do not enter sensitive personal information in that box.
5. Data sharing and sale
We do not sell, rent, trade or share personal information, because we do not collect it. The only data leaving your device is the technical data sent to the third-party services listed in section 4, solely to make the App function.
6. Data retention and deletion
We hold no user data, so there is nothing for us to retain or delete. Map points disappear when the App is closed. Saved preferences stay only on your device until you clear the App's data or uninstall it. Retention of data by the third-party services in section 4 is governed by their own policies.
7. Google Play
If you installed the App from Google Play, Google may separately collect information as described in the Google Play and Google Privacy Policies (for example, install and crash data if you have opted in on your device). We do not control or receive personal data from that collection.
8. Security
Because we do not collect or store your data, we hold nothing that could be breached on our side. Connections to the services in section 4 use HTTPS encryption.
9. Children's privacy
The App is a general-purpose utility and is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from anyone, including children.
10. Your rights (GDPR, UK GDPR, CCPA/CPRA and similar laws)
Because we do not collect or hold personal data about you, we have no personal data to access, correct, delete, port or restrict. If you believe we hold data about you, contact us at the email above and we will respond within a reasonable time. For data held by third-party services, please contact them directly.
11. Changes to this policy
We may update this policy from time to time. The "Last updated" date above will change when we do. Continued use of the App after an update means you accept the revised policy.

PART 2 – DISCLAIMER AND TERMS OF USE
By downloading or using the App you agree to the following. If you do not agree, please do not use the App.
1. For informational and estimation purposes only
The App provides approximate area, perimeter and unit-conversion results based on points you select on a map. It is intended for general reference, planning and rough estimation only.
2. No guarantee of accuracy
We do not guarantee that results are accurate, complete, current or error-free. Accuracy can be affected by, among other things:
- Satellite imagery that is outdated, misaligned, distorted, blurred, enlarged (over-zoomed) or unavailable for some locations;
- Your tap precision, screen size, zoom level and device limitations;
- Mathematical approximation – areas are computed on a spherical model of the Earth and may differ from results obtained with a surveying-grade (ellipsoidal or local-projection) method;
- Terrain and elevation – results are for the flat, projected map area, not the true sloping surface of the land;
- Boundaries drawn incorrectly or with crossing edges;
- Third-party services being inaccurate, delayed, changed or unavailable.
3. Not for legal, official or professional use
Results from the App must NOT be relied upon for legal, official, financial, engineering or professional purposes, including but not limited to:
- land purchase, sale, lease, mortgage, valuation or taxation;
- property registration, title, deeds, boundary or encroachment disputes;
- court, revenue-department, municipal or government submissions;
- construction, architecture, engineering or land-development decisions;
- insurance, subsidy or compensation claims.
The App is not a substitute for a licensed land surveyor, registered professional or official land records. Always obtain a professional survey and verify with the relevant authority before making any decision based on a measurement.
4. Local unit conversions
Traditional units such as Bigha, Biswa, Katha, Dhur, Kanal, Marla, Killa, Guntha, Cent and others are not standardised and can differ by country, state, district, village and by "pucca" or "kachha" convention. The values built into the App are commonly used approximations compiled from public sources and may be wrong or outdated for your locality. Always confirm the applicable unit size with local land records or the competent authority. The "Custom size" option lets you enter a specific value, and you are responsible for the value you enter.
5. Third-party content
Map imagery, labels and search results are provided by third parties (see Part 1, section 4) and remain subject to their own terms and attribution requirements. We are not responsible for their content, accuracy, availability or changes, or for any change in their terms that affects the App.
6. No warranty
The App is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including warranties of accuracy, reliability, merchantability, fitness for a particular purpose, non-infringement, or uninterrupted or error-free operation, to the fullest extent permitted by applicable law.
7. Limitation of liability
To the fullest extent permitted by applicable law, we, our developers and affiliates shall not be liable for any direct, indirect, incidental, consequential, special or punitive damages, or any loss of money, profit, data, property or opportunity, arising from or related to your use of, or inability to use, the App or reliance on any result it produces, even if we were advised of the possibility of such damages. You use the App and its results at your own risk and responsibility.
Nothing in this disclaimer excludes or limits liability that cannot be excluded or limited under applicable law.
8. Acceptable use
You agree to use the App lawfully and not to misuse it, reverse engineer it to the extent prohibited by law, or use it in a way that violates the terms of the third-party map and search services it relies on.
9. Changes and termination
We may modify, suspend or discontinue the App or these terms at any time without notice. Updated terms apply from the date they are published.
