Privacy Policy
1. Zero-PII principle
We do not collect, store or transmit the numbers you enter into the calculator (price, cost, category, weight, volume). Every calculation runs locally in your browser via JavaScript. The server never sees your business data.
2. What we do collect
- Anonymous analytics via Yandex.Metrica — only after you click "Accept" on the cookie banner. Aggregated pageviews, referrers, device type. No cross-site tracking.
- Server logs — IP address, User-Agent and requested URL, kept for 30 days for security purposes only.
3. URL sharing
When you press the "Copy link" button, we encode your input fields into URL parameters. This URL is generated locally and copied to your clipboard — we do not receive it. Anyone you send the link to will see the same numbers you see.
4. Cookies
We use two technical cookies: one for the cookie banner itself, one for analytics consent. Analytics cookies are set by Yandex.Metrica only after explicit consent.
5. LocalStorage
We save your last-used inputs in LocalStorage so you don't have to re-enter them on the next visit. This data stays on your device and is never transmitted. Clear your browser storage to remove it.
6. Your rights
Because we don't collect personal data, there is nothing to request, modify or delete on our side. For analytics data stored by Yandex, see Yandex.Metrica Terms.
