Local calculations
Entered integers, selected bases, and converted results are calculated in your browser. NumberBase has no product backend, account, database, saved history, or shareable result state.
Essential storage
Essential browser storage remembers only language and consent choices needed for the site experience. It does not save calculator values or results.
Optional analytics
Analytics loads only after consent and measures bounded public navigation events. It never records entered integers, selected bases, converted results, query state, or free-form content.
Control
You can reject optional analytics and reopen cookie settings at any time. The calculator remains usable with essential storage only.
