QuickAcuity — Privacy Policy and Terms

Summary

We minimize personal information collection. The app stores certain preferences and optional test history locally on your device. We use Firebase services to collect anonymous usage analytics, and we use Firebase/Firestore plus Resend for entitlement sync, purchase validation, support diagnostics, and optional referral invites. Most telemetry is anonymous or pseudonymous. When you choose to send a referral invite, we process the recipient email address and optional referrer name to deliver the email you requested.

Voice input is optional. QuickAcuity remains fully functional using on‑screen buttons or swipe gestures, and we only request microphone access if you choose to enable speech recognition.

Apple, Google, Firebase, and Resend may collect information as platform and service providers (e.g., crash logs, diagnostics, app store transactions, analytics, and email delivery metadata). See their privacy policies.

We do not collect audio recordings, speech transcripts, photos, or videos. From time to time, we may update our policies and this document if our data practices change.

Privacy Policy

1. Who We Are

Controller: Dirkes Medical, PLLC ("we", "us"). For any privacy questions, contact us at contact@dirkesmedical.com.

2. What We Collect

We designed QuickAcuity to minimize personal data collection. Specifically:

• On-device app data: the app stores settings and optional test history (e.g., date/time of test, letter size bucket per eye, mode, distance estimate, and any note you add) in local device storage. This data stays on your device unless you back it up with your OS vendor.
• Anonymous usage analytics: we use Firebase Analytics to collect anonymous usage data such as app events (e.g., test started, paywall viewed, purchase initiated). This helps us improve the app.
• Pseudonymous entitlement and support diagnostics: we use Firebase Anonymous Authentication to generate a random user ID for managing free trial allowances and purchase entitlements. We also store install-scoped entitlement records in Firestore, including the anonymous install ID, free trial usage, purchase history, referral status, and limited app/device metadata such as first-seen and last-seen timestamps, platform, app version, build number, device model, manufacturer, and OS version. This helps us detect stale or reused installs and troubleshoot support issues.
• Purchase validation data: when you make an in‑app purchase, we send anonymous data to Firebase Cloud Functions to validate your purchase with Apple or Google. This includes your anonymous install ID, product ID, purchase ID, and platform verification data. We do not receive your payment card details.
• Referral invite data: when you send a referral invite, we collect the recipient email address and optional referrer name, then process that information through Firebase Cloud Functions and Resend to deliver the invite and track its status. We also store limited invite metadata such as the referral code, tracking ID, and sent/opened/redeemed timestamps.
• Optional microphone access and speech recognition: QuickAcuity works entirely with tap or swipe input. If you enable speech recognition, we request microphone permission so your device’s operating system can grade spoken responses. Audio is processed by the OS (Apple or Google, depending on your device). We do not receive or retain your audio.
• Input and accuracy analytics (no recordings): to improve every mode, we log limited, anonymous telemetry about letter‑level outcomes such as the expected vs. recognized letter, confidence score, test mode, optotype, input method (voice, tap, or swipe), eye, line ID and position, viewing distance status, and aggregated timing (overall and per eye). This telemetry does not include audio recordings, full speech transcripts, photos, or videos, and is not linked to your identity.
• Camera and depth sensors: When available, we rely on Apple’s TrueDepth or ARKit scene-depth frameworks and Google’s ARCore depth APIs to estimate viewing distance automatically. Depth data is streamed from the front-facing camera, processed on‑device, and not stored or transmitted; no photos or videos are captured or kept. If your device lacks these sensors or you disable camera access, the app falls back to manual distance entry.
• Camera access: Granting camera permission lets us use these depth frameworks for automatic distance calibration. It is optional—the app still works with manual distance entry if you prefer not to allow the camera.
• No third‑party ads or trackers: we do not embed third‑party ad networks or tracking SDKs beyond Firebase services described above.
• No sale or sharing: we do not sell or share personal information as defined by applicable laws (e.g., CCPA/CPRA).

3. Platform Providers and Third‑Party Services

Distribution and certain system services are provided by Apple, Google, and Firebase (a Google service). They may collect data in their capacity as independent controllers. See:

• Apple Privacy Policy: https://www.apple.com/legal/privacy/
• Google Privacy Policy: https://policies.google.com/privacy
• Firebase Privacy Policy: https://firebase.google.com/support/privacy
• Resend Privacy Policy: https://resend.com/legal/privacy-policy

Examples include crash logs, device diagnostics, store receipts, optional speech services provided by the OS vendor, and analytics data processed by Firebase.

4. Legal Bases (GDPR)

We process limited pseudonymous data on our Firebase/Firestore backend to provide entitlement sync, purchase validation, support diagnostics, and referral features. For on‑device functionality, we rely on:

• Performance of the app: to provide requested features such as storing preferences and test history locally.
• Consent: for optional permissions like microphone and camera access; you may withdraw consent by disabling the permission in system settings.
• Legitimate interests: to improve recognition accuracy and test reliability using limited, aggregated telemetry (no recordings), validate in‑app purchases using anonymous store receipts or tokens, and keep entitlement and referral records consistent across devices.

5. Your Rights

Depending on your region (e.g., EU/UK GDPR, California CCPA/CPRA), you may have rights to access, correct, delete, or restrict processing of your personal data. These rights primarily apply to data controlled by Apple/Google and to the limited server-side records we keep for entitlements, purchases, referrals, and support diagnostics, as well as to data stored on your device.

• On-device data: you can clear the in‑app history in Settings/History (if available) or delete the app to remove local data. If your device backs up app data, removing backups may also be necessary.
• Platform data: exercise your rights directly with Apple or Google regarding store accounts, diagnostics, and purchases.
• Server-side records: contact us if you want us to review a request concerning entitlement, purchase, or referral records we maintain for support or fraud-prevention purposes.
• Contact us: we will assist where we are the controller. Email: contact@dirkesmedical.com.
• Complaint: you may lodge a complaint with your local data protection authority if you believe your rights have been infringed.

6. In‑App Purchases

We offer in‑app purchases for premium features. Payments are processed by Apple's App Store or Google Play. We do not receive your payment card details. We receive anonymous purchase metadata (e.g., a receipt or token, install ID, product ID, purchase ID) to grant entitlements and validate purchases through Firebase Cloud Functions. This data is not linked to personally identifiable information.

7. International Transfers

Most on-device test history stays on your device, but we do transfer limited pseudonymous entitlement, purchase-validation, and referral data to Firebase/Firestore when you use those features. Platform providers (Apple/Google/Resend/Firebase) may transfer data per their policies, using appropriate safeguards.

8. Retention

On‑device data persists until you clear it in the app or uninstall the app. We retain limited server-side entitlement, purchase-validation, referral, and support-diagnostic records for as long as needed to operate the app, prevent duplicate redemptions, resolve support issues, and meet legal obligations.

9. Children’s Privacy

QuickAcuity is not intended for children under 13 without supervision. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us to request deletion.

10. Security

We apply reasonable safeguards for local storage and for the limited server-side records we maintain. However, no mobile device or cloud service can be completely secure; keep your device and backups protected.

11. Changes to This Policy

We may update this Privacy Policy to reflect changes in features, regulations, or platform requirements. We will post updates in the app and/or on our website. Continued use after changes means you accept the updated policy.
