MonyPortal – Privacy Policy

Last updated: January 24, 2026

This Privacy Policy explains how your information is handled when you use the MonyPortal mobile application ("the App"). MonyPortal is a cryptocurrency portfolio tracker that stores all portfolio data locally on your device and offers a free (ad-supported) version with an optional premium upgrade (ad removal).

By using MonyPortal, you agree to the terms in this Privacy Policy.

1. Information We Collect

1.1. User-provided data (stored locally)

The App allows you to manually enter the following data:

• Crypto assets you add (e.g., BTCUSDT, ETHUSDT)
• Quantity/amount information for each asset
• Buy/sell prices
• Transaction history (transaction type, amount, price, date/time)
• Premium purchase status (whether ads are removed)

1.2. Backup and export data

The App allows you to export your portfolio as a JSON file. This feature:

• Saves the file to your device's storage
• Lets you choose whether to share it via email, cloud storage, messaging apps, etc.
• Does not automatically send data to any server
• The JSON file contains: assets, quantities, and transaction history

1.3. Automatically collected technical data

The App may indirectly access the following technical information for proper functionality:

• Device type, operating system, and version
• App version
• Error and crash reports (aggregated by Google Play or the OS)

This data is primarily processed by Google Play and the operating system, and may be shared with the developer as anonymous/statistical reports.

2. Third-Party Services and SDKs

The App uses the following third-party services:

2.1. Google AdMob (Advertisements)

To provide free access to the App, we display banner and interstitial ads via Google AdMob.

• AdMob may collect device identifiers, advertising IDs, IP addresses, usage statistics, and similar data
• This data is processed by Google for ad delivery, performance measurement, and fraud prevention
• The App itself does not collect additional profile or identity data; however, AdMob may process data according to its own privacy policy

For more information: Google AdMob Privacy & User Data

As required by Google Play, we have indicated in the Play Console's "App content" section that the App contains ads. We comply with Google Play's privacy policy guidelines: Google Play Help Center

2.2. Google Play Billing & Apple In-App Purchase (IAP)

The App offers a one-time premium purchase to remove ads.

• Payment transactions are handled by Google Play Store or Apple App Store
• The developer never has access to payment information such as credit/debit card numbers
• The App only receives confirmation from the respective store that the premium product was purchased, and marks the premium status locally on the device

For more information, refer to the respective store policies:

• Google Play Terms of Service and Privacy Policy
• Apple App Store Privacy Policy

2.3. Binance WebSocket (Market Data)

The App uses Binance WebSocket API to fetch real-time cryptocurrency prices and USDT trading pairs.

How it works:

1. The App connects to Binance's public WebSocket stream
2. Binance broadcasts real-time price data to all connected clients (this is public information)
3. The App receives these prices and uses them for portfolio calculations on your device
4. Your portfolio data (what coins you own, quantities, purchase prices) never leaves your device

What Binance knows: A device connected to their public WebSocket (IP address)
What Binance does NOT know: Your portfolio contents, transaction history, or any personal information

3. How We Use the Information

We use the collected data for the following purposes:

• Display and update your cryptocurrency portfolio and transaction history
• Calculate total portfolio value, profit/loss, and similar financial summaries
• Provide portfolio backup and restore functionality
• Display advertisements and enable the premium (ad-free) experience
• Improve the App's performance, reliability, and stability

We do not sell, rent, or use your personal data for third-party marketing purposes.

4. Data Storage and Security

• Your portfolio and transaction data is stored on your device via AsyncStorage
• Other apps cannot directly access this data; however, rooted devices, backup apps, or malware could theoretically pose a risk
• While we take reasonable technical measures to secure data, no mobile application can guarantee 100% security

To delete your data:

• Use the "Clear All" feature in the App to delete all assets and transaction history
• Uninstall the App (the mobile OS may delete local data)
• Clear app data from your device settings

5. Children's Privacy

The App:

• Does not target individuals under 18 years of age
• Does not contain content or marketing specifically for children
• Does not knowingly collect personal data from children

If you believe a child has used this App and provided personal information, please contact us; we will take steps to delete such data within a reasonable timeframe.

Depending on your region's data protection laws (e.g., GDPR, KVKK), you may have the following rights:

• Access the data held in the App

7. Data Sharing

We may share your personal data only in the following circumstances:

Beyond these circumstances, we do not share your data with third parties for marketing purposes.
