Privacy Policy

What it includes:

• Coordinates, transformations, bearings, and distances
• Traverse, resection, and intersection computations
• Curve geometry, level book, and elevation data
• Measured GPS points, project notes, and annotated photos

How it is handled:

• Computed and stored locally on your device
• Not uploaded to our servers, except in the optional Benchmark Navigation Pro cloud feature described below
• Shared or exported only when you explicitly choose to
• Deleted when you delete it in-app or uninstall the app

The optional RTK Survey feature connects to an external GNSS/RTK receiver you own and, if you choose, to an NTRIP correction service (caster) that you configure. It is used only when you open the RTK screen and set it up.

What it involves:

• The app reads position data (standard NMEA-0183) from your receiver over Bluetooth, USB, or Wi-Fi
• To receive corrections, the app connects to the NTRIP caster you enter and, for network/VRS mounts, sends the receiver's approximate position to that caster so it can return corrections for your area
• The NTRIP host, port, mountpoint, username, and password you enter are your caster's credentials — stored locally on your device only
• RTK points, jobs, and fix status you record are stored locally on your device, the same as your other surveying work

Important:

• The NTRIP caster is a third-party service that you choose and sign in to — it is not operated by APPNEST, and we do not receive your position, your NTRIP credentials, or your RTK data
• If you never use RTK Survey, no receiver is connected and nothing is sent to any caster

What we store:

• Unit preferences (meters, feet, yards; area units)
• Coordinate and distance precision settings
• Favorite and recently used tools
• App configuration and consent choices

Storage method:

• Stored locally on your device only, in Android app storage
• Used solely for app functionality
• Not sold, and not shared with third parties
• Removed when the app is uninstalled

What may be transmitted:

• Device and app identifiers (for example app instance ID and advertising identifier)
• App version, device model, operating system, language, timezone, and network state
• Approximate IP-based region information (such as country, city, and network provider)
• Crash diagnostics and operational events
• A Google Play Integrity token, used to confirm the app is a genuine, unmodified install

How it is used:

• To keep the app reliable, detect crashes, and improve performance
• To deliver the in-app updates feed and notify you of new versions
• To protect the app and our servers against tampering, fraud, and abuse
• To support analytics and ad delivery through the SDK partners listed below

Supported formats:

• Import: CSV, Excel (.xlsx), KML, LandXML, and DXF files you select
• Export: Excel, PDF, CSV, and DXF
• Sharing via the Android share sheet (email, cloud drive, messaging, and so on)

Your control:

• Files are read only when you pick them in the system file picker
• Nothing is imported, exported, or uploaded automatically
• You choose what to include and where it goes

Benchmark Navigation Pro is an optional paid module. It is the one feature that stores your surveying data on our servers, so that your benchmark jobs are available across sessions and devices.

• To use it you sign in with your email address, which we verify with a one-time code. The email identifies your workspace so your jobs stay yours across devices.
• Benchmark jobs and the benchmark points you import from CSV are stored in your workspace on our servers, together with your email and a device identifier
• This happens only if you purchase and use this module
• If you never use it, we never receive your email address and no surveying data is sent to our servers
• Email us at [email protected] to delete your workspace, cloud jobs, and email address

The app never requires an email address to use its surveying tools. We only receive one in these two optional cases, and only because you chose to provide it:

• Benchmark Navigation Pro: if you buy and sign in to the optional paid module (see above), your email identifies your cloud workspace
• Contacting us: if you send feedback or a support message from the app and choose to include your email so we can reply

How we treat it:

• Used only for that purpose — your workspace, or replying to you
• Never sold, and never shared with advertisers or any other third party
• Not used for marketing unless you separately subscribe to our newsletter
• Email [email protected] at any time to have it deleted

The app offers an optional monthly subscription to remove ads, and an optional paid Benchmark Navigation Pro module. Purchases are handled entirely by Google Play Billing.

• We never see or store your card, bank, or payment details
• The app receives only a purchase confirmation from Google Play to unlock the feature
• Users who previously bought the one-time ad removal keep it permanently
• Subscriptions can be cancelled anytime in the Google Play Store

Your surveying work (calculations, measured points, project notes, annotated photos, settings, favourites, and any AI Assistant history and API key) is stored only on your device. You can remove it at any time, with no request to us:

• Delete individual items inside the app
• Clear the AI Assistant conversation in the AI Assistant chat, and remove your API key in AI Setup
• Or use Android Settings → Apps → Land Surveyor → Storage → Clear data
• Uninstalling the app deletes all of it permanently

We hold server-side data only if you used one of the two optional features described above. To have it erased, email us:

[email protected]

Put "Land Surveyor data deletion request" in the subject and send it from the email address you used in the app.

What we delete:

• Your Benchmark Navigation Pro workspace — all cloud jobs, imported benchmark points, your email address and the linked device identifier
• Any feedback or support message you sent us, including the email address you gave for a reply

Good to know:

• Requests are actioned within 30 days, and we confirm by email once done
• Deletion is permanent and cannot be undone
• There is nothing to delete if you never used Benchmark Navigation Pro and never contacted us — we hold no email address or surveying data for you
• Anonymous analytics and diagnostics are not linked to your identity and cannot be traced back to an individual user
