Verify the ZIP
Compare its SHA-256 with the value on this page and in the receipt.
One practical guide from download and installation to a calibrated first plan, a clear estimate, and a recoverable local project.

A clean first hour
Keep the receipt and original ZIP. Work through these steps in order, then create a project package before the project becomes business-critical.
Compare its SHA-256 with the value on this page and in the receipt.
Use the verified setup EXE and confirm the Windows publisher before running it.
Import a drawing, confirm its known dimension, then measure and price scope.
Back up, verify the new ZIP, and retain the prior installer until the project passes its integrity check.
1 · Package contents
The paid customer package keeps the tested setup installer, terms, checksums, and signing details together. It is not a customer download until the status below says it is Authenticode-signed and your purchase receipt supplies it.

2 · Verify the download

Stop if the hash differs. Delete that copy and download it again from the original receipt. Do not run a package from a forwarded attachment or third-party mirror.
3 · Install Takeoff
Takeoff uses a private 127.0.0.1 address on your PC to run the interface. Other devices on your network cannot connect to that address.
4 · First project
Construction quantities and prices still require professional review. A clean calibration and a visible link back to the drawing are part of the estimate, not optional setup chores.
5 · Back up and transfer
Takeoff stores project data under the current Windows user's application-data folder. Takeoff does not add application-level encryption to those files, so use Windows device encryption or BitLocker and a protected Windows account when plans are sensitive. Keep the folder on a backed-up PC and use Takeoff's own recovery tools as deliberate checkpoints.
Test a restore on a copy of a project before relying on a new backup routine. A diagnostics report can help support, but it cannot restore your project.
6 · Update and roll back
Takeoff checks for updates only when you ask. Settings shows the installed version, project format, stable channel, and current release-details link.
No earlier release is available yet. Keep the installer you actually received. Uninstalling Takeoff preserves project data by default.
7 · Support safely
Use the Diagnostics action in Settings to collect environment, file-integrity, and backup details without drawings or full project contents. Review every file before sending it. Share a full Project Package only when you deliberately choose to share that project.
Open the private-first support center or email Takeoff support.
Know exactly what is installed
Settings shows the installed version, project format, update channel, and file-integrity status. We checked the panel before and after moving the application; both launches showed the same version without making a background internet request.
Version 0.1.0 is the first release, so there is no earlier version to roll back to yet. Keep the installer you receive until a newer release has been installed and checked successfully.

How local storage works
Takeoff can be moved or updated without relocating the project store. Your plans and estimates remain on the Windows PC you control and can be reopened without an internet connection.
Keep a current backup of the project store before moving or updating the application.
