Cookie policy

The short version: this site sets no cookies at all. Nothing here tracks you, profiles you, or follows you to other sites.

What we store instead

The app keeps your working data in your browser's local storage — a private space on your own device that is never transmitted to us or anyone else:

Essential — your settings (units system, theme, precision) and the one flag that remembers you've seen the welcome tour.
Functional — favorites, history, saved invoices and receipts. Disable or clear these any time in the app's Settings.
Live data — when enabled, the currency/crypto/markets tools fetch public rates from exchange APIs. Those are anonymous requests for numbers; no personal data is sent.

Analytics and advertising

There are none. No analytics script loads unless you explicitly allow it in the cookie preferences, and as of today none is configured at all. There is no advertising, ever.

Payments

There is no checkout on this site — iSmart Measure is 100% free — so no payment provider ever sets a cookie here. Every bit of storage is first-party and stays on your device.

Clearing everything

App Settings → Reset, or clear this site's data in your browser. Both wipe every locally stored value instantly.
