A mathematically rigid field ledger for surveyors, civil engineers, and landscape architects. Translate bearing angles, segment lengths, and survey markers into closed geometric balances — with no cellular link and zero data leaving your device.
Four tools that turn physical survey markers into verifiable geometry — fast numerical entry tuned for a high-visibility technical workspace.
Run manual calculations for property limits. Input linear distances and directional sector parameters to evaluate total perimeter trajectories instantly.
Keep an organized local archive of terrain calculations. Log total square metrics and sector coordinates alongside your own custom location labels.
Direct manual checks that isolate error margins and balance geometric vertices across irregular, real-world parcels.
Fluid text navigation with sharp haptic triggers on every submission and ledger reset — feedback you feel, even in the field.
Sketch a rectangular parcel from two corner coordinates and a bearing offset. Watch the plot, perimeter, and area recompute live — a taste of the on-device calculation the app runs offline.
Drag to survey · corners lock to grid
Demonstration only · the app performs full closed-loop survey math offline. Nothing here is transmitted.
We're the small team behind Staek: Land Matrix — surveyors, engineers, and builders who got tired of dragging bulky software and cellular dependencies into the field. We built the tool we always wanted: a precise, offline calculation desk that lives in your pocket and never phones home.
Our mission is simple. Give land professionals a rigid, dependable way to compute boundaries, areas, and vector closures without invasive tracking or expensive data links. Every measurement you enter stays yours, on your device, under your command.
Staek: Land Matrix hands you a technical dark workspace tuned for fast entry — input bearing angles and segment lengths, evaluate perimeter trajectories, log square metrics with custom labels, and run closed-loop checks to isolate error margins across irregular parcels. Your private field ledger, plot by plot.
No accounts. No background sync. No third-party monetization frameworks. Just a mathematically rigid tool that respects your work and your privacy in equal measure — every session, every parcel, every time.
Coordinates you command.
Effective Date: June 2026
Staek: Land Matrix is built on one uncompromising principle: your survey data is yours alone. This application does not collect, store externally, or transmit any personal or project information. Every calculation happens entirely on your device.
Nothing. Staek: Land Matrix requires no account, no name, no email, and no sign-in. We do not request or access your device location, embed no analytics, and track no usage. The values you enter — bearing angles, segment lengths, perimeter trajectories, area calculations, and custom location labels — remain on your device and are never seen by us.
Because we collect no information, there is nothing for us to use, analyze, profile, or sell. Every feature — the Boundary Layout Matrix, the Land Area Estimation Ledger, and the Vector Closed-Loop Calc — runs fully on-device. Your survey work never leaves your hardware and is never processed on any external system.
All entries you create are stored locally on your device only. There is no cloud backup, no remote database, and no server synchronization. We maintain no copies of your terrain calculations or location labels anywhere outside your device.
Staek: Land Matrix integrates no third-party analytics platforms, no advertising networks, no behavioral trackers, and no data-harvesting SDKs. Nothing in the app reports back to us or to any outside party.
Because your data never travels beyond your device, it is insulated from server breaches, interception, and remote exposure. The app operates as a self-contained, offline calculation desk, keeping your field records under your physical control at all times.
Staek: Land Matrix collects no data from any user, including children under the age of 13, and is compliant with COPPA principles. Since no personal information is ever gathered, there is nothing to expose regardless of who uses the app.
You hold complete control over everything stored in the app. Because there are no accounts and no external backups, removing your data is as simple as deleting the application — this permanently clears all locally stored calculations and labels from your device.
We may revise this policy occasionally to reflect improvements or legal requirements. When we do, the Effective Date above will be updated. Continued use of the app after changes indicates acceptance of the revised terms.

📬 We'd love to hear from you — Staek: Land Matrix gets sharper every time a surveyor in the field tells us what they need.
