FairDome is operated by RONSTECH LLC ("we," "our," or "us"), a limited liability company registered in the State of Florida. We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application ("App").
1. Information We Collect
1.1 Information You Provide
- Account Information: When you create an account, we collect your email address, display name, and authentication credentials. If you sign in through Google or Apple, we receive your name and email address from those services.
- Household Data: Information about your household members, including names and monthly income (used solely for proportional expense calculations).
- Expense Data: Details of expenses you enter, including amounts, categories, descriptions, dates, and which household member paid. We do not collect or store credit card or bank account numbers.
- Receipt Images: If you use receipt scanning, we process images you capture to extract expense information. See Section 4 for details on how these images are processed.
- Shopping Lists: Items and store preferences you enter when using the Smart Shopping Itinerary feature.
1.2 Information Collected Automatically
- Device Information: Device type, operating system version, and unique device identifiers.
- Usage Data: How you interact with the App, features used, and error logs.
- Push Notification Tokens: Firebase Cloud Messaging (FCM) tokens used to send you notifications about household activities. You can disable push notifications in your device settings at any time.
- Location Data: With your explicit permission, we collect your device's precise geographic location to provide Smart Shopping Route recommendations. The starting point you generated a route from is saved with that route, so the route can be reopened and its distances still make sense; it is deleted when the route is deleted. We do not track your location in the background. You can revoke location access at any time through your device settings.
- Camera and Photos: If you use the receipt scanning feature, we access your device camera or photo library to capture receipt images for expense data extraction. The image is kept, attached to the expense it produced, so you and your household can look at the receipt behind a figure later. It is stored in Firebase Storage and is readable only by members of your household. Deleting the expense deletes the image.
1.3 Biometric Authentication
If you enable biometric login, the App uses your device's biometric capabilities (e.g., Face ID, Touch ID, fingerprint). All biometric data is processed and stored exclusively on your device by the operating system. Biometric data is never transmitted to or accessible by our servers.
2. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the FairDome App
- Calculate proportional expense shares based on household member incomes
- Sync your data across devices in real time
- Send push notifications about expense updates, settlements, and task assignments
- Process subscription purchases through RevenueCat and the Apple App Store or Google Play Store
- Process receipt images to automatically extract expense data (AI-powered)
- Generate optimized shopping itineraries based on your location and shopping list
- Respond to your requests and provide customer support
- Detect and prevent fraud or abuse of the service
3. Legal Basis for Processing (EEA/UK Users)
If you are located in the European Economic Area (EEA) or the United Kingdom, we process your personal data on the following legal grounds under the General Data Protection Regulation (GDPR):
- Performance of Contract: Processing your account, household, expense, and settlement data is necessary to provide the FairDome service you signed up for.
- Consent: We process location data, camera/photo access, receipt images sent to third-party AI services, and push notifications based on your explicit consent. You may withdraw consent at any time through your device settings or by contacting us.
- Legitimate Interest: We process device information and usage data for fraud prevention, service security, error diagnosis, and service improvement, where our interests do not override your fundamental rights.
4. Data Storage, Processing, and Security
Your data is stored and processed using the following services:
- Neon (Postgres, hosted on Amazon Web Services in Ohio, United States): Stores your household, member, expense, share, settlement, task, shopping and subscription data, encrypted at rest and in transit. This is where the record of your money lives.
- Fly.io (Ashburn, Virginia, United States): Runs the application programming interface that every request from the App goes through. It is the only thing that reads or writes the database; the App itself has no direct access.
- Firebase Authentication (Google): Manages your account credentials securely, including Google Sign-In and Apple Sign-In integrations. Your account identifier from this service is what links you to your household data.
- Firebase Storage (Google): Stores receipt images you attach to expenses.
- Firebase Cloud Messaging (Google): Delivers push notifications to your device.
Until 1 September 2026 household, expense, settlement and task data were stored in Cloud Firestore (Google). That data was migrated to Neon and the Firestore copy is now a read-only historical archive that the App no longer writes to.
We implement industry-standard security measures including encryption at rest and in transit, access controls, and regular security reviews. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
5. Data Sharing and Third-Party Processors
We do not sell, rent, or trade your personal information to third parties. We may share your data with the following parties:
- Household Members: Other members of your household can see shared expense data, balances, task assignments, and settlement information. Income data you provide is used for proportional calculations and the resulting share percentages are visible to household members.
- Service Providers: Third-party services that help us operate the App:
- Neon: The Postgres database that holds your household data.
- Fly.io: Hosting for the interface between the App and that database.
- Firebase / Google Cloud Platform: Authentication, receipt image storage, push notifications, crash reporting, and the nightly job that creates recurring expenses.
- RevenueCat: Subscription management. Receives your anonymous user ID and purchase information to manage your subscription status.
- Apple App Store / Google Play Store: App distribution and in-app purchase payment processing.
- OpenAI: AI-powered receipt text extraction, shopping list optimization and monthly spending insights. Receives receipt text, shopping list contents, and—for monthly insights only—the first names of your household members alongside what each of them spent. It does not receive your email address, your account identifier, or your bank or card details. Requests reach OpenAI from our own server; the App never holds a key to it.
- Veryfi: Receipt OCR fallback service. Receives receipt images for data extraction when primary processing is unavailable.
- Google Places API: Store location and address data used to generate Smart Shopping Itinerary routes.
- Google ML Kit: On-device text recognition from receipt images. All ML Kit processing occurs locally on your device; no data is sent to external servers.
- People you send a payment link to: If you create a link to an expense, anyone holding that link sees that one expense — its name, date, amount, who paid, and the first names of the members who share it with what each still owes. No account is needed to open it, so treat the address itself as the key and send it only to the person concerned. You can revoke a link at any time from the expense it belongs to. No other expense, no email address, and no household identifier is shown on that page.
- Legal Requirements: We may disclose your information when required by law, subpoena, or court order, or to protect our rights, property, or safety.
6. Your Rights and Choices
Depending on your location, you may have the following rights regarding your personal data:
- Access: Request a copy of the personal data we hold about you.
- Correction: Update or correct inaccurate or incomplete data.
- Deletion: Request deletion of your account and all associated data.
- Data Portability: Request a machine-readable copy of your data to transfer to another service.
- Restrict Processing: Request that we limit how we process your data in certain circumstances.
- Object to Processing: Object to processing of your data based on legitimate interests.
- Withdraw Consent: Withdraw consent for location access, camera access, push notifications, or AI-based processing at any time through your device settings or by contacting us. Withdrawal does not affect the lawfulness of prior processing.
- Opt-out of Notifications: Disable push notifications in your device settings at any time.
To exercise any of these rights, contact us at privacy@fairdome.app. We will respond within 30 days. We may need to verify your identity before processing your request.
6.1 For EEA/UK Residents
If you are located in the EEA or UK, you also have the right to lodge a complaint with your local data protection supervisory authority if you believe we have not adequately addressed your concerns.
6.2 For California Residents (CCPA)
If you are a California resident, you have the following additional rights under the California Consumer Privacy Act (CCPA):
- Right to Know: You may request disclosure of the categories and specific pieces of personal information we have collected about you in the preceding 12 months, the categories of sources, the business purpose for collection, and the categories of third parties with whom we share data.
- Right to Delete: You may request deletion of your personal information, subject to certain exceptions.
- Right to Non-Discrimination: We will not discriminate against you for exercising your CCPA rights.
- Sale of Personal Information: We do not sell your personal information to third parties, and we have not done so in the preceding 12 months.
To submit a CCPA request, contact us at privacy@fairdome.app.
7. Data Retention
We retain your data for as long as your account is active and as needed to provide you the service.
What closing your account does, exactly. Your profile is cleared, your sign-in is deleted, your devices stop receiving notifications, any invitations you sent are cancelled, and you leave every household you belong to. This happens immediately, not within 30 days.
What it cannot do is remove you from the shared record. Every expense, share and payment in a household names who paid it, and those records belong to the other members as much as to you: deleting your half would change what everybody else is owed and leave amounts that no longer add up. So the expenses, shares, settlements and receipt images of a household remain with that household, and your email address is retained as the key those records point at. Nothing else about you is kept, and you can ask us what remains.
If you want the shared record itself removed, every member of the household has to ask for it, and we will delete the household and everything in it. Write to us and we will confirm before anything is deleted.
8. Children's Privacy
FairDome is not intended for use by anyone under the age of 16 in the European Economic Area or under the age of 13 in the United States. We do not knowingly collect personal information from children. If we become aware that we have collected personal information from a child below the applicable age, we will take steps to delete that information promptly. If you believe a child has provided us with personal data, please contact us at privacy@fairdome.app.
9. International Data Transfers
Your data may be transferred to and processed in the United States and other countries where our service providers (including Neon, Amazon Web Services, Fly.io, Google, OpenAI, RevenueCat, and Veryfi) operate. These countries may have data protection laws that differ from those of your country. When we transfer data outside the EEA/UK, we rely on the European Commission's Standard Contractual Clauses (SCCs) and other appropriate safeguards to ensure your data is protected in accordance with this Privacy Policy and applicable law.
10. Automated Decision-Making
FairDome uses AI-powered features for receipt scanning (automatic text extraction) and smart shopping itinerary optimization. These automated processes extract data from receipt images and suggest shopping routes, but they do not make decisions that produce legal effects or similarly significant effects on you. You can always manually review and edit any AI-extracted data before it is saved.
11. Data Breach Notification
In the event of a data breach that poses a risk to your rights and freedoms, we will notify the relevant supervisory authority within 72 hours of becoming aware of the breach. If the breach poses a high risk to your personal rights, we will also notify you directly via the email address associated with your account.
12. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the new Privacy Policy on this page, updating the "Last Updated" date, and sending a notification through the App. Your continued use of the App after the effective date of the revised policy constitutes your acceptance of the changes.
