Cookie and storage policy
Last updated: 15 September 2026
The calculator does not set HTTP cookies. Cookie rules can also apply to localStorage and similar device storage, so optional storage is off by default.
What is stored
| Item | Purpose | Duration |
|---|---|---|
| g0i-privacy | Remember selected privacy preferences and choice date; written when you choose | Until reset or browser deletion |
| g0i-history | Optional saved inputs and results, up to 50 | Until cleared, overwritten, or saving disabled |
| g0i-settings / calculatorSettings | Optional currency rates, source and update dates | Until replaced, disabled or deleted |
| privacyChoices | Mirror preferences for the browser extension | Until reset or extension removal |
| selection | Transfer text explicitly chosen through the extension context menu | Until loaded into the calculator, or cleared |
Your choice
Use Privacy settings to accept individual optional features or reject all. Rejection does not prevent ordinary offline calculations. No analytics or advertising consent is requested because neither is installed. Consent for optional features is not bundled with acceptance of terms.
The preference record respects your explicit choice. Enabling Office may introduce storage controlled by Microsoft and the Office host; those components are not present on an ordinary calculator page. If third-party tracking or embeds are added later, this policy and the actual loading controls must be reviewed before deployment.
