FIELD NOTE 01
Local browser storage
The Upgrade ROI Calculator and Progress Tracker use versioned localStorage so entries survive a return visit. The site sanitizes stored data and recovers to a safe state when it is corrupt or from an unsupported version.
You can reset either tool from its interface. Clearing site data in your browser also removes local state.
FIELD NOTE 02
Share and export
Copy Share Link encodes only the supported tool fields into the current URL. No share URL is placed in the sitemap, and opening malformed or oversized state falls back safely.
Copy Export places tracker JSON on your clipboard when browser permission allows it. The site does not create a server account or upload that export.
- No account required
- No server-side tool database
- No hidden gameplay values
- Query URLs are non-canonical
FIELD NOTE 03
Advertising and third parties
The advertising seam supports off, ranking, growth and harvest modes, but missing or invalid configuration defaults to off. At this stage, there are no real Adsterra keys and no active provider placements.
Official Steam and source links take you to third-party sites with their own privacy practices. If real advertising or analytics becomes active, this policy must be updated to match the actual configuration.
