Privacy Policy

Last Updated: April 29, 2026

Welcome to ShareBills. This Privacy Policy explains how Kiosoft ("we," "us," or "our") collects, uses, discloses, and protects your information when you use the ShareBills mobile application (the "App") available on iOS and Android platforms.

By using ShareBills, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 Information You Provide

  • Account Information: When you create an account, you may provide your name, display name, and email address. Email is optional if you choose to use the app as a guest.
  • Transaction Data: Expense information you enter, including amounts, descriptions, dates, categories, and how expenses are split among participants.
  • Receipt Images: Photos of receipts you upload for record-keeping or receipt scanning purposes.
  • Item Detection Images: Photos of items or spaces you upload to the item detection feature to identify and estimate the value of inventory items.
  • Group Information: Names and details of expense-sharing groups you create, including participant names and email addresses you add.

1.2 Information Collected Automatically

  • Device Information: Device brand, model, operating system and version, screen resolution, timezone, and locale settings.
  • App Information: App version and usage patterns.
  • Push Notification Tokens: If you enable push notifications, we collect tokens necessary to deliver notifications to your device.
  • Anonymous Usage Analytics: If you have not opted out, we collect anonymized usage data such as which screens you visit and which features you use, to help us improve the App. No personal or financial data is included in analytics.

2. How We Use Your Information

We use the information we collect to:

  • Provide the Service: Enable expense tracking, splitting, and sharing functionality.
  • Authentication: Verify your identity through email-based one-time passwords (OTP) or guest authentication.
  • Receipt Scanning: Process receipt images to automatically extract transaction details using optical character recognition.
  • Item Detection: Process images you upload to identify inventory items, their estimated condition, and their estimated resale value using a third-party AI vision model.
  • Notifications: Send push notifications about shared expenses, group updates, and account activity.
  • Improve the App: Analyze usage patterns to enhance features and user experience.
  • Security: Detect and prevent fraud, abuse, and security incidents.

3. Third-Party Services

We use the following third-party services to operate ShareBills:

3.1 Receipt Scanning

We use third-party AI services to process receipt images and extract transaction data. When you use the receipt scanning feature, your receipt images may be sent to one of the following providers depending on your account type and the processing method selected:

  • Microsoft Azure Document Intelligence: Your receipt images are sent to Microsoft Azure servers for OCR processing. See Microsoft's Privacy Statement for details.
  • Google Gemini: Your receipt images may also be processed by Google's Gemini AI model. The same free/paid tier distinction described in Section 3.2 applies: free accounts use Google's unpaid API, where Google may use your content to improve their AI products; premium accounts use the paid API tier, where your content is not used for model training.

3.2 Google Gemini (Item Detection)

We use Google's Gemini AI vision model to power the item detection feature. When you upload an image to this feature, the image is transmitted to Google's servers for analysis. Before the image is transmitted, we re-encode it to remove embedded camera metadata such as GPS location and device identifiers. The image itself may still contain incidental information visible in the photo (for example, other people, documents, or screens); please be mindful of what is captured in frame before uploading.

Which Gemini tier processes your image depends on your ShareBills account type:

  • Free accounts: Your images are sent to Google's free (unpaid) Gemini API. Under Google's terms for unpaid services, Google may use content you submit, including your images and the model's responses, to improve and develop their AI products. Human reviewers at Google may also see this content, though Google states it is disconnected from your account before review.
  • Premium accounts: Your images are sent to Google's paid API tier. Under Google's terms for paid services, your prompts and responses are not used for model training.

See the Gemini API Additional Terms of Service and Google's Privacy Policy for the full details. If you'd prefer your images not be used for training, upgrading to a premium account is the way to go.

3.3 Expo Push Notifications

We use Expo's push notification service to deliver notifications to your device. Expo's Privacy Policy covers how they handle this data — you can read it at expo.dev/privacy.

3.4 Analytics

We use PostHog to collect anonymous usage data within the App, such as screen views and feature usage patterns. No personal or financial data is shared with this service. You can opt out of analytics at any time in the App settings. Read more in PostHog's Privacy Policy.

3.5 RevenueCat (Subscription Management)

We use RevenueCat to manage in-app subscriptions and purchases. When you subscribe to a premium plan, your anonymized user identifier and subscription lifecycle events (such as purchases, renewals, cancellations, and expirations) are shared with RevenueCat. RevenueCat does not receive your name, email address, or financial data such as expense information. See RevenueCat's Privacy Policy for details on how they handle this data.

3.6 Mailgun (Email Delivery)

We use Mailgun to deliver transactional emails, including one-time login codes and account notifications. When we send you an email, your email address and the email content are transmitted to Mailgun's servers for delivery. See Mailgun's Privacy Notice for details.

3.7 App Integrity Verification

To protect against tampered or unauthorized versions of the App, we use platform-provided integrity verification services. On Android, the App uses Google Play Integrity API, which sends device and app attestation data to Google to verify that the App is genuine and running on a trusted device. No personal or financial data is included in these checks. See Google's Privacy Policy for details.

4. Data Storage and Security

4.1 Data Location

Your data is stored on servers located in Canada. By using ShareBills, you consent to the transfer and storage of your information in Canada.

4.2 Data Retention

  • Account Data: Retained until you request account deletion.
  • Transaction Data: Retained until you delete the transaction or request account deletion.
  • Receipt Images: Retained until you delete the associated transaction or request account deletion.
  • Item Detection Images: Not retained by ShareBills after analysis. The results of the analysis (detected item names, brands, categories, and estimated prices) are retained until you delete the associated record or request account deletion.

4.3 Security Measures

We take reasonable steps to protect your data, including:

  • Encryption of data in transit using TLS/SSL
  • Secure password hashing for authentication codes
  • Rate limiting to prevent abuse
  • Device fingerprinting for security verification

5. Data Sharing

We don't sell your personal information or share it with third parties for marketing or advertising. We may share your information in these circumstances:

  • With Group Participants: When you share expenses in a group, other participants can see relevant transaction details and your name/display name.
  • Service Providers: With third-party services as described in Section 3, solely to provide the App's functionality.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new Privacy Policy within the App and updating the "Last Updated" date at the top of this page. Continuing to use ShareBills after changes are posted means you accept the updated policy.
