MyBit (Upbit) (operated by Dalin Soft, the "App") values your privacy. This policy explains what information the App handles and how it is used.
Summary
· The App has no sign-up and no login. It does not collect, transmit, or store your personal information on any developer server (the developer does not operate a server for this App).
· Your exchange API key, trade records, and settings are stored only on your device.
· Google or Samsung processes some information for ad display (Google AdMob) and subscription payments (Google Play or Galaxy Store).
(1) Exchange connection information
| Items | Upbit Open API Access Key, Secret Key |
|---|---|
| How it is provided | You enter it yourself on the settings screen of the App |
| Important | Your API key is never sent to or stored on any developer server. It is stored in encrypted form only in the secure storage of your device (e.g., FlutterSecureStorage). The App uses it only to send the order and query requests you set up to the Upbit exchange. |
(2) Information stored on your device
| Items | Strategies you set up, order/fill/trade logs, backtest and optimization records, notification records, app lock setting, and subscription status check records (for offline checks) |
|---|---|
| Where | Stored only inside your device. Not sent anywhere. |
(3) Subscription payments (Google Play or Galaxy Store)
| Processor | Depending on the store the App was installed from: Google LLC (Google Play Billing) or Samsung Electronics Co., Ltd. (Galaxy Store In-App Purchase, Samsung In-App Purchase) |
|---|---|
| What happens | Payment, renewal, cancellation, and refunds for the Premium subscription are handled by the store the App was installed from (Google Play or Galaxy Store). The App does not receive or store card numbers or other payment details. It only stores the result of the subscription check on your device. |
(4) Advertising identifiers (ad SDK)
| Items (examples) | Advertising ID, device and event information, IP address, approximate location, etc. — processed by the Google AdMob SDK to serve ads |
|---|---|
| Processor | Google LLC (Google AdMob / Google Mobile Ads) |
| Purpose | Showing interstitial and rewarded ads to free users, measuring ad performance, and preventing fraud |
| Note |
The App itself does not separately collect or store the above information; the scope of processing follows Google's policies.
(https://policies.google.com/technologies/ads) You can reset your advertising ID or opt out of personalized ads in your device settings. No ads are shown while you have a Premium subscription. |
The App uses the permissions below. Some, such as notifications, are up to you to allow. Main features such as market data, charts, and backtesting work even if you do not allow them.
| Permission | Purpose |
|---|---|
| Internet / network state | Communicating with the Upbit exchange (market data, orders, balance), ads, and subscription checks; checking connection status. |
| Notifications | Order and fill alerts, trading signal alerts, and showing background running status. The App works without it; only notifications will not be shown. |
| Foreground service | Keeps your strategies running and market data in sync even when the App is not on screen or the screen is off. A notification is shown while it runs. |
| Battery optimization exemption | Reduces the chance of the operating system's power saving stopping background running. You choose whether to allow it; the App works without it. |
| Wake lock | Prevents processing from being cut off when the device sleeps while a strategy is running. |
| Fingerprint / biometrics (app lock) | When you turn on the app lock, your identity is checked with your device's screen lock (fingerprint, PIN, or pattern). The App does not store biometric data; the operating system handles it. |
| Vibration | Vibration when showing notifications |
| Billing (Google Play Billing or Samsung In-App Purchase) | Premium subscription payment and subscription status check (Google or Samsung, depending on the store you installed from) |
| Advertising ID | Serving ads and measuring performance (Google AdMob) |
※ The App does not request location, contacts, phone, SMS, photos, camera, or microphone permissions.
※ You enter your exchange API key yourself, and it is stored only in the secure storage of your device (see 1 (1)).
| Category | Items (examples) | Retention |
|---|---|---|
| Exchange API key | Access Key, Secret Key | Stored on your device only (not on any server). Removed when you delete or change it in the App, or uninstall the App. |
| Settings, trade logs, backtest records, etc. | Data stored on your device | Until you use the in-app delete/reset features or uninstall the App |
| Advertising identifiers, etc. | Processed by the ad SDK | According to Google's policies (you can reset your advertising ID or opt out of personalized ads in your device settings) |
| Subscription payment information | Google Play or Galaxy Store billing records | According to the policies of each store (Google or Samsung) |
The App does not store your personal information on any developer server, so there is no separate account deletion process. Information stored on your device (API key, logs, settings, etc.) is removed when you use the in-app delete/reset features or uninstall the App.
The App does not collect your information on any developer server and, in principle, does not provide it to third parties.
The App uses the external services below to provide its features. If their content or the services used change, this policy will be updated.
| Provider | Role | Items (examples) |
|---|---|---|
| Google LLC (Google Play / Google Play Billing) | Premium subscription payment and subscription status check when installed from Google Play | Google Play billing information (processed by Google; the App does not receive it directly) |
| Samsung Electronics Co., Ltd. (Galaxy Store / Samsung In-App Purchase) | Premium subscription payment and subscription status check when installed from Galaxy Store | Samsung billing information (processed by Samsung; the App does not receive it directly), and the results of subscription product, purchase ID, and subscription end date lookups |
| Google LLC (Google AdMob / Google Mobile Ads) | Showing ads to free users, measuring performance, and preventing fraud | Advertising ID, device and event information, IP address, approximate location, etc. |
The App uses Google's global infrastructure for Google Play Billing and ads (Google AdMob), and Samsung In-App Purchase for Galaxy Store billing, so information may be processed on servers outside your country (e.g., the United States) when using these services. No information is transferred to any developer server.
| Recipient | Country | Items (examples) | Purpose | When / how | Retention |
|---|---|---|---|---|---|
| Google LLC | United States and other service countries | Advertising ID, device and event information, IP address, approximate location, etc. | Ad display and performance measurement | Sent over the network when ads are shown | According to Google's policies |
| Google LLC | United States and other service countries | Google Play billing information | Subscription payment processing | Sent over the network at payment/check time | According to Google's policies |
| Samsung Electronics Co., Ltd. | Republic of Korea and other service countries | Samsung billing information and subscription status check information | Galaxy Store subscription payment processing | Sent over the network at payment/check time | According to Samsung's policies |
You can view, change, or delete your API key in the App and reset stored records. Uninstalling the App removes all information on your device. You can reset your advertising ID and opt out of personalized ads in your device settings. You can cancel and request refunds for your subscription directly in the subscription management of the store you subscribed through (Google Play or Galaxy Store).
The App is not intended for use by anyone under 19 (the age of majority in Korea) and does not knowingly collect information from children.
If this policy is changed, we will notify you in the App at least 7 days before the change takes effect.
