Rate Koto / Android app

Privacy, explained.

This policy explains what the Android app Rate Koto: Taka Rate Today (package com.zubaer.ratekoto) does with data. The app is made by Md. Zubaer Ahammed.

Last updated:

What the app itself collects

Nothing. The app has no accounts and no sign-in. I do not run a server for it and I do not receive anything about you.

The country you choose, your language and theme, your rate alert, the log of money you sent home and your checklist ticks are kept only on your device. They are removed when you clear the app’s data or uninstall the app. If your device has Android backup switched on, Google may include them in your own device backup.

The app never asks for bank, card or payment details, and it does not send or hold money.

Exchange rates

To show rates, the app downloads a public list of exchange rates from Frankfurter (frankfurter.dev). If that is unavailable it uses the Currency API files hosted on jsDelivr and Cloudflare Pages, or ExchangeRate-API. These requests contain no personal information, but each service sees your IP address, as any website does. The last rates downloaded are kept on your device so the app works offline.

Advertising

The app is free and shows adverts through Google AdMob (the Google Mobile Ads SDK) on some screens. It never shows adverts on the Send and Convert screens, in notifications or in the widget. To show and measure adverts, and to prevent fraud, Google may collect and use:

  • your device’s advertising ID and other device identifiers;
  • your IP address, from which an approximate location can be worked out;
  • information about your device, such as model, operating system version and language;
  • how you interact with adverts and the app, and diagnostic information such as crash and performance data.

This data goes directly from your device to Google and its advertising partners. I do not receive it in a form that identifies you.

Purchases

“Remove ads” is a one-time purchase handled entirely by Google Play. I do not see your payment details. The app only asks Google Play whether the purchase has been made, so that it can turn adverts off on your devices.

Your choices

  • Where the law requires it (for example in the European Economic Area, the United Kingdom and Switzerland), the app asks for your consent before any advert is requested. You can change your answer at any time in About > “Ad privacy choices”.
  • You can reset or delete your advertising ID, or turn off personalised adverts, in your device settings under Google > Ads.
  • No adverts are loaded while you are offline, and none at all after you buy “Remove ads”.

Permissions

  • Notifications, asked only when you turn on a rate alert or the daily rate note.
  • Internet, network state and the advertising ID, for exchange rates, adverts and the Google Play purchase.

The app does not ask for your location, contacts, camera, microphone, files or photos. Call buttons open your phone’s dialler with the number filled in; the app does not make calls itself.

Some buttons open Google Play, your email app, your dialler, a share sheet, this website, or official websites such as those of Bangladesh Bank, the National Board of Revenue and government ministries. Those apps and sites have their own privacy policies. The app is not affiliated with any of them.

Children

The app is made for adults and is not directed at children. I do not knowingly collect personal information from children.

Changes and contact

If this policy changes, the new version will be published on this page with a new date. For privacy questions or requests, email [email protected]. The policy for this website itself is the zubaer.com privacy policy.
