Privacy Policy
In short: there are no accounts. We do not ask for your name or email, and we do not sell your information. The only thing the calculator sends to us is the ZIP code you ask about. What you calculate and your history stay on your own device. The free Android app shows ads from Google, which has its own data practices described below.
Who we are
The Sales Tax Calculator is made by Euphrates Group (“we”, “us”). You can reach us at support@euphrates-group.com.
What stays on your device
- Your recent calculations (the last 25), the settings you chose, and a saved copy of the latest exchange rates. In the website and Windows app this is kept in the browser or app storage; in the Android app it is kept in the app’s private storage.
- We cannot see this information. You can remove it with “Clear all” in History, by clearing the app’s data in your device settings, or by uninstalling the app.
What is sent to our service
- A ZIP code, when you look up a rate, so we can return the sales tax rate for it. We keep each ZIP code’s public rate result for up to 24 hours so we do not ask our rate source twice. It is not linked to you.
- A request for exchange rates, when you open the calculator. It contains nothing about you.
- Like any internet service, our service provider, Cloudflare, receives the technical details of each request (such as your IP address) in order to deliver the service, limit abuse and keep it secure. We do not use this to build a profile of you and we do not keep it ourselves.
- Prices, discounts and totals you type are worked out on your device. They are not sent to us.
Other companies involved
- SalesTaxZip.com receives the ZIP code from our service to look up the rate. Your IP address and device details are not passed on to it.
- European Central Bank daily reference rates are fetched by our service. Nothing about you is sent.
- Google Fonts supplies the typeface on the website, so your browser contacts Google when the page opens.
- Google AdMob (free Android app only) shows one banner ad. Google may collect and use your device’s advertising ID, approximate location from your IP address, device and app information and ad interactions to serve and measure ads and to prevent fraud. See Google’s Privacy Policy and how Google uses information from apps that use its services.
- Google Play handles the optional subscription and your payment. We never see your card or name. The app only asks Google Play whether this Google account has an active “Remove ads” subscription.
Your choices about ads
- Where the law requires it (for example in the European Economic Area, the United Kingdom and some other regions), the Android app shows Google’s consent form before any ad is requested. If you decline, no ads are requested. You can reopen your choices from “Ad privacy settings” in the Remove ads panel when your region requires it.
- On Android you can reset or delete your advertising ID, or opt out of ads personalization, in your device’s Settings under Google, then Ads.
- A “Remove ads” subscription turns the banner off. You can cancel at any time under Subscriptions in Google Play.
Children
The calculator is a general business and shopping tool and is not directed at children under 13. We do not knowingly collect information from children.
Keeping and deleting information
We do not hold personal information about you, so there is nothing for us to delete or export. Data on your device is yours to clear as described above. For data held by Google (advertising or Google Play), use your Google Account controls at myaccount.google.com.
The numbers are estimates
Tax rates come from a third-party source and a ZIP code can cover more than one county or city. Please confirm the rate for real transactions. The calculator is not tax, legal or accounting advice.
Changes
If this policy changes we will update the date at the top of this page. If a change affects what the apps send or collect, we will say so in the app’s release notes.
