Version 1.3

Privacy Policy

Your privacy matters to us. This Privacy Policy explains how Coral Dash collects, uses, stores, and protects your information when you use our service.

1. Introduction

Coral Dash ("we", "us", "our") is committed to protecting your privacy and handling your personal data responsibly. This Privacy Policy describes our practices regarding the collection, use, and disclosure of your information.

Important: Coral Dash is an independent project and is not affiliated with, endorsed by, or connected to Monzo Bank Ltd. We do not have direct access to your Monzo account or banking credentials.

By using Coral Dash, you consent to the data practices described in this policy. If you do not agree with our practices, please do not use our service.

2. Information We Collect

2.1 Account Information

When you create an account, we collect:

  • Email address (via Google OAuth)
  • Name and profile information (as provided by Google)
  • Account preferences and settings you configure

2.2 Google Account Data

When you connect your Google account, we request read-only access to:

  • Your Google Sheets files: To read transaction data from your selected spreadsheet
  • File access via Google Picker: You select your spreadsheet using Google's native file picker, which grants us access to only that specific file

We use this data to:

  • Retrieve your transaction data from the connected spreadsheet
  • Process and display your financial information in the dashboard
  • Generate insights, summaries, and reports

We only access the specific spreadsheet you authorise. We do not modify, create, or delete any files. See Section 5 for complete details on Google data handling.

2.3 Usage Data

We may automatically collect information about how you use the service:

  • Pages and features you access
  • Time spent on the service
  • Device information (browser type, operating system)
  • IP address

2.4 Payment Information

Payment processing is handled entirely by Stripe, a PCI-compliant payment processor. We do not store your complete credit card number, CVV, or other sensitive payment details on our servers. We may receive and store:

  • Last four digits of your card (for display purposes)
  • Card type and expiry date
  • Billing address
  • Stripe customer ID

2.5 Trading 212 Data

If you choose to connect your Trading 212 account, we collect and process the following information:

  • API Credentials: Your Trading 212 API key is stored using industry-standard encryption (AES-256). We never store your API key in plain text.
  • Account Balances: Cash, invested, and total portfolio values.
  • Positions & Holdings: Details of assets held, including quantity, value, and performance metrics.

This data is used solely to calculate and display your net worth and investment performance. We do not execute trades or modify your Trading 212 account in any way.

2.6 Mortgage & Property Data

If you choose to use the mortgage tracking feature, we collect and process the following information:

  • Property Information: Address, postcode, property type, number of bedrooms, and number of bathrooms.
  • Mortgage Details: Outstanding balance, interest rate, remaining term, lender name, monthly payment amount, and mortgage type (e.g. fixed, variable, tracker).
  • Chimnie Property Data: We use the Chimnie API to retrieve enriched property information for UK addresses, including estimated valuations, council tax band, EPC rating, transaction history, and floor area. This data is stored alongside your mortgage record.
  • Valuation History: Property valuations are tracked over time to provide historical charts and equity calculations.
  • Overpayment Scenarios: Any mortgage overpayment simulations you create, including amounts and frequencies.

This data is used to display mortgage metrics such as equity, loan-to-value (LTV) ratio, amortisation schedules, and to integrate your property as an asset within your net worth overview.

Important: Coral Dash does not provide mortgage advice, property advice, or valuations of any kind. Property valuations displayed are estimates sourced from third-party data and should not be relied upon for financial decisions.

3. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and maintain the Coral Dash service
  • Process your subscription and manage your account
  • Display your financial data and generate insights
  • Send you service-related communications (account updates, billing notices)
  • Respond to your enquiries and provide customer support
  • Improve and optimise the service
  • Detect and prevent fraud or abuse
  • Comply with legal obligations

We do not sell, rent, or share your personal data with third parties for their marketing purposes.

Coral Dash uses the following third-party services to operate. By using our service, you acknowledge that your data may be processed by these providers in accordance with their respective privacy policies:

Our Technology Stack

    Your account data and application data are stored on Supabase's cloud infrastructure. Supabase provides row-level security and encryption. We adhere to Supabase's security best practices.

    Supabase Privacy Policy

  • Vercel (Hosting & Infrastructure)

    The Coral Dash application is hosted on Vercel's global edge network. Vercel may process request logs and performance data.

    Vercel Privacy Policy

  • Stripe (Payment Processing)

    All payment transactions are processed by Stripe, a PCI DSS Level 1 certified payment processor. We never have access to your full card details.

    Stripe Privacy Policy

  • Google (OAuth & Sheets API)

    We use Google OAuth for authentication and the Google Sheets API to access your authorised spreadsheet data.

    Google Privacy Policy

  • Trading 212 (Investment Data)

    We use the Trading 212 Public API to retrieve your account and portfolio data.

    Trading 212 Privacy Policy

  • Chimnie (UK Property Data)

    We use the Chimnie API to retrieve property details, valuations, and enriched property information for UK addresses as part of the mortgage tracking feature.

    Chimnie Terms

We follow the security best practices and guidelines established by these providers. However, we cannot guarantee the security practices of third-party services beyond what they publicly disclose.

5. Google Account Integration

When you connect your Google account to Coral Dash, we request the following read-only permissions:

Permissions We Request

  • Google Drive (File Access)

    drive.file

    This is the only Google permission we request. It allows us to access only the specific spreadsheet you select through Google's native file picker. We cannot see, browse, or access any other files in your Drive.

    This scope is sufficient for both selecting your file via the Picker and reading transaction data from it via the Google Sheets API. We only read data — we never modify, create, or delete any spreadsheet content.

Privacy note: We intentionally use this minimal scope so that the consent screen accurately reflects what we access: "files you open with this app" rather than "all your spreadsheets".

What We Store

  • OAuth refresh token: Stored encrypted in our database to maintain your Google connection
  • Selected spreadsheet ID: To remember which spreadsheet to sync from
  • Synced transaction data: Transaction data imported from your spreadsheet

What We Do NOT Do

  • Modify, create, or delete any files in your Google account
  • Access any files other than your explicitly selected spreadsheet
  • Share your Google data with third parties
  • Use your data for advertising, profiling, or marketing purposes
  • Retain your data after you request deletion

Revoking Google Access

You can disconnect your Google account at any time from your account settings. When you disconnect:

  • Your OAuth tokens are immediately deleted from our database
  • Your stored spreadsheet ID and configuration are cleared
  • We lose all access to your Google account and data
  • Previously synced transaction data remains in your Coral Dash account unless you request its deletion

You can also revoke access directly from your Google Account at any time by visiting Google Account Permissions.

Google API Services Compliance

Coral Dash's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

6. Data Storage & Security

We implement industry-standard security measures to protect your data:

  • All data is transmitted over HTTPS (TLS encryption)
  • Database access is protected by row-level security policies
  • Authentication is handled via secure OAuth protocols
  • Sensitive credentials (like Trading 212 API keys) are stored using AES-256 encryption
  • Access to production systems is restricted and logged

Your data is primarily stored on Supabase's cloud infrastructure, which may be located in data centres in the United States or other regions. Vercel's edge network operates globally.

7. Data Loss Disclaimer

IMPORTANT NOTICE

While we take reasonable measures to protect your data, we cannot guarantee the absolute security or availability of your data. By using Coral Dash, you acknowledge and accept the following:

  • No guarantee of data availability: Service interruptions, outages, or technical failures may occur at any time, potentially resulting in temporary or permanent loss of access to your data.
  • No responsibility for data loss: We are not responsible for any loss, corruption, or unauthorised access to your data, whether caused by system failures, security breaches, third-party actions, or any other circumstances.
  • Third-party dependencies: We rely on Supabase, Vercel, Google, and other third-party providers. Failures or issues with these services may impact your data and are outside our control.
  • User responsibility: You are solely responsible for maintaining your own records and backups of your financial data. Coral Dash should not be your only source of financial records.
  • No data recovery guarantee: In the event of data loss, we cannot guarantee that your data can be recovered.

We strongly recommend that you maintain independent records of your financial information and do not rely solely on Coral Dash for critical financial data storage.

8. Data Retention

We retain your personal data for as long as your account is active or as needed to provide you with the service.

  • Active accounts: Data is retained while your subscription is active.
  • Account deletion: Upon your request to delete your account, we will delete your personal data within 30 days, except where we are required to retain it for legal purposes.
  • Legal retention: We may retain certain data as required by law (e.g., transaction records for tax purposes) or to protect our legal rights.

Google Data Retention

For data obtained through your Google account connection:

  • OAuth tokens: Deleted immediately when you disconnect your Google account or delete your Coral Dash account
  • Synced transaction data: Retained until you request deletion or delete your account. You can request deletion of synced data while keeping your account active.
  • Spreadsheet metadata: Your selected spreadsheet ID is deleted when you disconnect your Google account

Trading 212 Data Retention

For data obtained through your Trading 212 integration:

  • API Credentials: Your encrypted API keys are deleted immediately when you disconnect the integration or delete your account.
  • Historical Data: Snapshots of your account value may be retained to provide net worth history charts, even after disconnection, unless you explicitly request deletion or delete your account.

Property & Mortgage Data Retention

For data associated with the mortgage tracking feature:

  • Property & Mortgage Data: Your property details, mortgage information, and overpayment scenarios are stored while your account is active and deleted upon account deletion or upon request.
  • Valuation History: Historical property valuations are retained for charting purposes and deleted when you remove the mortgage or delete your account.
  • Chimnie Data: Cached property details retrieved from Chimnie are deleted when you remove the mortgage or delete your account.

You can disconnect your Google account independently of deleting your Coral Dash account. This allows you to remove Google access while retaining other account data.
