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
Eligible pages use active third-party advertising formats, including display, native, popunder and social-bar units. The provider may receive information commonly sent with web requests, such as IP address, browser and device details, referring page, and may use cookies or browser storage according to its own policies. The privacy and disclaimer routes are excluded from these advertising placements.
Sponsored gaming-offer links are labeled as sponsored and open a third-party destination in a new tab. Official Steam, source and sponsored links lead to sites with their own privacy practices. This site does not claim control over those third parties, and it currently operates no separate first-party analytics system.
