Minimal data by design.
The current DeckCalculator does not require an account and does not store your deck projects in a central database.
Saved projects
When you use “Save project,” your current calculator settings are stored locally in your browser. They stay on that device and are not uploaded to a DeckCalculator project database.
Shared project links
When you use “Copy link,” the calculator settings are included in the URL so the same project can be restored when the link is opened. Anyone with the link can view those project settings.
Accounts and payment data
DeckCalculator currently has no user accounts, central project database, or payment checkout. If those features are added later, this page will be updated before they go live.
Analytics
DeckCalculator uses Umami, a privacy-focused analytics service, to understand anonymous website usage such as page visits and calculator interactions. Complete shared-project query strings, deck dimensions, and entered prices are not sent to Umami.
Security
DeckCalculator uses HTTPS and browser security protections. Current calculations and saved projects stay in your browser rather than being stored in a DeckCalculator user database.
