Cookies & browser storage

Preferences you choose

Favourites, preferred currency and logo selection are stored under toolzcraft.preferences.v1 in localStorage on this browser profile. They remain until you reset them in My tools or clear site data. Other people using this profile can see them. They are not synced with your account. No salary figures, uploaded files or calculator inputs are saved in this preferences record.

Authentication and resource caches

If sign-in is configured, Firebase manages authentication persistence in browser storage. Signing out ends the active sign-in but does not delete the operator's account records. Browsers may cache application files and OCR language resources. Clear site data in your browser settings to remove local records and caches; doing so can sign you out.

Advertising choices

This version does not run advertising code or set advertising cookies. It does not present a pretend consent banner for services that are not running. If advertising is introduced, the operator must publish the actual vendor disclosures and provide the required consent and withdrawal controls before those services run.
