Privacy Policy
We keep this simple. There are no accounts, no sign-ups, and no advertising trackers. Here is exactly what happens to your data.
Stays in your browser
Your recent queries (history) and your selected country are saved locally in your browser using localStorage. They never leave your device and we can't see them. Clear them any time by clearing this site's data in your browser.
Sent to our server
When you run a calculation, the text of your query and your selected country are sent to our server so it can compute the result. We use them only to return your answer and to keep anonymous, aggregate usage statistics (for example, counts and response times). We don't build profiles or try to identify you.
AI help for queries we can't read
If your query isn't in a form the calculator understands, we send it to an AI model. It either rewrites the query into our calculator's syntax, which we then compute, or answers your question directly, in its own words. Only in that case is the text of your query sent on to OpenRouter, which routes it to the model provider serving the request; their handling of it is governed by their own policies. Queries the calculator understands on its own never leave our server. This is the same request to OpenRouter that already happened whenever a rewrite was used — a direct answer doesn't add a second call, it only changes what the model is allowed to send back.
When a rewrite is used, the page shows you the expression we actually calculated. When the model answers directly instead, the page marks it as an AI answer so it can't be mistaken for the calculator's own result — because it isn't one: the answer is stated by the model, not computed from our exchange-rate feeds, and it carries no rate, date, or breakdown. It's also capped at 120 characters of plain text. Money mentions are dropped rather than shown — a currency symbol, a currency name we recognize, or a code attached to an amount — so the shapes we can detect never reach your screen looking like a real rate — the AI answer marking is what covers the rest.
Cookies
None. The calculator doesn't set cookies.
Third parties
- Exchange rates come from the Central Bank of Russia and the European Central Bank. We fetch these ourselves, so using the calculator doesn't share your data with them.
- The page loads the Inter font from Google Fonts, which means your browser contacts Google's servers to download the font.
- OpenRouter receives your query text only when the calculator can't read it on its own, as described above.
