All Currency Converter Offline

1.Overview

All Currency Converter Offline ("the app", "we", "us") is a currency conversion utility for Android built to work fully offline using cached exchange rates. The app does not require a login, an account, or any form of authentication — you can start converting currencies the moment you open it.

This Privacy Policy explains what limited information the app and its advertising partner (Google AdMob) handle, how conversion history and settings are stored on your device, and the controls you have over all of it.

2.Data we collect

The app itself does not ask you to type in, upload, or submit any personal information (no name, email, phone number, or payment details are ever requested). The table below summarizes the only data categories involved, and who is responsible for each one.

See Section 6 for the full advertising disclosure.

3.Data we don't collect

• No account registration, sign-in, or password of any kind.
• No name, email address, phone number, or postal address.
• No payment or financial account information (the app performs arithmetic currency conversion only — it never connects to a bank, card network, or payment processor).
• No precise location (GPS) data is requested or read.
• No access to your contacts, photos, microphone, or camera — the app never requests these permissions.
• No first-party analytics or crash-reporting SDK is bundled in this app.

4.Local storage & your history

Everything you personally create while using the app stays on your device:

• Conversion history — the amounts and currency pairs you convert, saved automatically so you can revisit them later.
• Favorite currencies & pairs — the currencies and pairs you star for quick access.
• App settings — default currencies, number format, theme, update frequency, offline mode, and haptic feedback preference.

None of this is uploaded to any server we operate — there is no backend for this app to send it to. It is stored locally using Android's DataStore and is removed automatically if you clear the app's storage or uninstall the app.

5.Exchange rate updates

The app fetches publicly available currency exchange-rate data from a static, read-only JSON file hosted on GitHub, according to the Update Frequency you've set in Settings (every 24 hours by default). This is a plain HTTPS download of a public data file — no personal data, device identifiers, or anything you've typed into the app is sent with this request.

If no connection is available, or Offline Mode is switched on in Settings, the app skips this request entirely and keeps working using the last rates it already has stored locally.

6.Advertising (Google AdMob)

This app displays advertising supplied by Google AdMob — a small anchored banner shown near the bottom of every screen, and an occasional full-screen interstitial ad shown only at natural pauses (for example, right after you finish choosing a different currency). Ads are never shown while you're actively typing, scrolling, or at app launch or exit.

To serve and measure these ads, Google and its advertising partners may collect and process identifiers such as your device's advertising ID, general device information, and app interaction data, in accordance with Google's own privacy policy. We do not control what Google's ad network collects beyond configuring the ad placements themselves.

• How Google uses information from sites/apps that use its services: policies.google.com/technologies/partner-sites

If you are in the European Economic Area, the UK, or Switzerland, you may be shown a consent message before ads are personalized, in line with applicable regulations. You can also reset or limit ad personalization for your device from your Android system settings at any time (Settings → Privacy → Ads / Google → Ads).

7.App permissions

• Internet access — required to download exchange-rate updates and to serve ads.
• Network state — used only to detect whether the device is online or offline, so the app can decide whether to fetch new rates.

The Google Mobile Ads SDK included in this app may declare the advertising ID permission automatically on supported Android versions, strictly for the advertising purposes described in Section 6. The app requests no other sensitive runtime permissions.

8.Children's privacy

This app is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with information, please contact us using the details in Section 13 so we can address it.

9.Your controls

• Clear history — delete individual conversions or use "Clear All" on the History screen at any time.
• Offline Mode — stop the app from making any automatic network requests, from Settings.
• Theme & Haptics — customize the app's look and vibration feedback from Settings.
• Uninstall — removing the app deletes all locally stored history, favorites, and settings from your device.
• Ad personalization — manage or reset your advertising ID and ad personalization from your device's system settings.

10.Security

All network requests made by the app — both for exchange-rate updates and for serving ads — are made exclusively over encrypted HTTPS connections. Since the app has no account system and stores your data only on your own device, there is no central database of user data for us to safeguard or that could be breached on our end.

We may update this Privacy Policy from time to time — for example, if we add a new feature or change how ads are configured. The "Effective date" at the top of this page will always reflect the latest revision. We encourage you to review this page periodically.
