Projects in the cloud

Projects, with their locations, places, client details, "prepared by" and subcontractors, are kept in db.json on the data branch of this repository. Everyone who opens the calculator sees them, on any device, with no login.

To save from a device, click Cloud in the calculator and paste a GitHub key once (a classic token with only the public_repo scope). The key stays in that browser. Photos and patente files are not sent online.

Files in this repository

File	What it is
index.html	The current version, the page at the link above
versions/	Earlier versions, one file per version (led-calculator_v74.html … )
CHANGELOG.md	List of changes for each version

The whole app is one HTML file. To use it offline, download index.html and open it in a browser. PDF export needs an internet connection to load its library.

Updates

New versions replace index.html, the previous version is kept in versions/, and the change is written in CHANGELOG.md. The site updates a minute or two after each push.
