Privacy Policy

Last updated: May 2026

This Privacy Policy describes how SmartGrid™ Studio ("we", "us", or "our") collects, uses, and protects information from users ("User") of the SmartGrid™ Personal Finance Hub web application at app.smartgridstudio.com ("the App"). By using the App, you agree to this policy.

1. Information We Collect

Personal identification information

When you register, we collect your email address. You may also optionally provide a display name. We collect only the minimum information required to provide the service.

Financial data you enter

All financial data you enter into the App (accounts, transactions, savings goals, commitments, assets, subscriptions) is stored securely in your account. This data belongs to you and is never shared with third parties.

Non-personal usage information

With your consent, we may collect anonymised usage data (pages visited, features used) via Google Analytics to understand how the App is used and improve it. This data cannot identify you personally.

2. How We Use Your Information

To provide the service

Your email is used for account authentication, password resets, and service notifications.

To improve the App

Anonymised usage data (only collected with your consent) helps us identify which features are most used and where improvements are needed.

To communicate with you

We may send transactional emails (account confirmation, security alerts) and, if you opt in, product update emails. You can unsubscribe from marketing emails at any time.

3. Data Storage & Security

Where your data is stored

Your data is stored on Supabase (PostgreSQL), hosted on servers in the United States. By using the App, you consent to your data being processed there.

Security measures

All data is encrypted in transit (HTTPS/TLS). Database access is protected by row-level security — no user can access another user's data. We implement industry-standard security practices.

No data selling

We do not sell, rent, or trade your personal or financial information to any third party, ever.

4. Cookies

Essential cookies

We use session cookies required for authentication. These cannot be disabled without breaking the login functionality.

Analytics cookies

With your explicit consent, we use Google Analytics cookies to understand usage patterns. You can decline these via the cookie banner and the App will continue to work fully.

Your choice

You can change your cookie preference at any time by clearing your browser's localStorage and reloading the App — the consent banner will reappear.

5. Your Rights (GDPR & Privacy Laws)

Right to access

You can export all your data at any time from Settings → Export Data.

Right to deletion

You can delete your account and all associated data from Settings → Account. Deletion is permanent and irreversible.

Right to correction

You can edit any data you've entered directly within the App.

Right to portability

Your data can be exported in CSV format from the App.
