# Privacy Policy

**Last Updated: January 2026**

Aleksandr Popov built the Expenses app as an expense tracking application. This SERVICE is provided by Aleksandr Popov at no cost and is intended for use as is.

This page is used to inform you about my policies regarding the collection, use, and disclosure of Personal Information if you decide to use my Service.

If you choose to use my Service, then you agree to the collection and use of information in relation to this policy. The Personal Information that I collect is used for providing and improving the Service. I will not use or share your information with anyone except as described in this Privacy Policy.

## Information Collection and Use

The Expenses app is designed with privacy in mind. I do not collect or store sensitive personal information such as email addresses, payment card details, or financial account information.

### Data Stored in Firebase

The app uses Firebase (Google's cloud service) to store the following data:

**User Information:**
- Your display name (as provided during sign-in)
- User ID (generated by Firebase Authentication)
- Authentication provider (Google or Apple)
- Current and previous expense space IDs

**Expense Data:**
- Expense amounts, dates, and categories
- Optional notes you add to expenses
- Currency information

**App Data:**
- Custom expense categories you create
- Shared expense spaces and their members
- Aggregated statistics for expense tracking

**What I DON'T Store:**
- Email addresses
- Payment information
- Location data
- Device identifiers
- Any other sensitive personal information

### Authentication

The app uses secure authentication provided by:
- **Google Sign-In**: Authenticates via your Google account
- **Apple Sign-In**: Authenticates via your Apple ID

These authentication providers handle your login credentials. I only receive a user ID and your display name (if provided) from these services. I do not have access to your email address or password.

### In-App Purchases

The app uses RevenueCat to process in-app purchases. RevenueCat handles all payment processing. I do not collect, store, or have access to your payment information. All purchases are processed through Apple's App Store or Google Play Store.

## Third-Party Services

The app uses the following third-party services that may collect information:

- **Firebase (Google)**: Used for data storage and authentication
  - [Firebase Privacy Policy](https://firebase.google.com/support/privacy)
  - [Google Privacy Policy](https://www.google.com/policies/privacy/)

  - [RevenueCat Privacy Policy](https://www.revenuecat.com/privacy)

- **Firebase Analytics**: Used to understand how the app is used (anonymized data)
  - [Firebase Analytics Privacy](https://firebase.google.com/policies/analytics)

## Data Security

I value your trust in providing your information. All data is stored securely in Firebase, which uses industry-standard security measures. However, remember that no method of transmission over the internet or electronic storage is 100% secure, and I cannot guarantee absolute security.

## Data Deletion

You can delete your account and all associated data at any time by:
1. Deleting the app from your device
2. Contacting me at spealcy@gmail.com to request data deletion

I will delete your data within 30 days of your request.

## Children's Privacy

This Service does not address anyone under the age of 13. I do not knowingly collect personally identifiable information from children under 13. If I discover that a child under 13 has provided me with personal information, I will immediately delete this from our servers. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact me so that I can take necessary action.

## Changes to This Privacy Policy

I may update this Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. I will notify you of any changes by posting the new Privacy Policy on this page.

This policy is effective as of January 2026.
