Introduction

This Privacy Policy describes how HantaScan ("we," "our," or "us") collects, uses, and shares information when you use our mobile application (the "App"). HantaScan is a utility application that helps users scan and assess spaces for hantavirus risk indicators using their device's camera, photo library, and location. By using the App, you agree to the collection and use of information in accordance with this Policy.

Effective Date: 2026-05-20

Information We Collect

We collect the following categories of information to provide and improve the App:

Camera Images and Photos: When you use the scan feature, the App processes images captured by your device's camera or selected from your photo library to analyze spaces for hantavirus risk indicators.
Location Data: With your permission, we collect your approximate or precise location to display outbreak risk information near you and map-based features.
Device Information: Device model, operating system version, unique device identifiers, language, time zone, network status, and app version.
Usage Data: Information about how you interact with the App, such as features used, screens viewed, session duration, taps, scrolls, and crash reports.
Advertising Identifiers: With your permission (via App Tracking Transparency on iOS and Advertising ID on Android), we may collect your advertising identifier to personalize ads.
Purchase Information: If you purchase a subscription or in-app product, we receive transaction confirmations from the App Store or Google Play (processed via RevenueCat). We do not collect or store your payment card details.
Account Information: If you sign in, we may collect your authentication identifiers via Firebase Authentication.
Push Notification Tokens: A unique token used to deliver push notifications to your device, if you opt in.

Permissions We Request

The App requests the following device permissions, each of which can be granted or denied at any time in your device settings:

Camera: Required to scan physical spaces and capture images for hantavirus risk analysis.

Denying a permission may limit certain functionality, but you may continue to use parts of the App that do not require that permission.

Advertising

The App displays advertisements provided by Google AdMob and may use Facebook Audience Network and TikTok ad attribution services. Ads may include banner, interstitial, rewarded, and app-open formats. We may serve personalized ads only if you grant permission via the App Tracking Transparency prompt on iOS or do not opt out of personalized ads on Android. If you decline tracking or opt out, you will still see ads, but they may be less relevant. You can purchase a premium subscription to remove ads entirely.

Data Sharing and Disclosure

We do not sell your personal information. We share information only in the following circumstances:

With Service Providers: Trusted third parties (listed above) that perform services on our behalf, bound by confidentiality and data protection obligations.
For Legal Reasons: When required by law, regulation, legal process, or governmental request, or to protect our rights, property, or safety, or that of our users or others.
Business Transfers: In connection with a merger, acquisition, financing, or sale of all or a portion of our business or assets.
With Your Consent: When you explicitly authorize sharing.

Data Retention

We retain your information for as long as necessary to provide the App's services and for legitimate business purposes, such as complying with legal obligations, resolving disputes, and enforcing our agreements. Crash logs and analytics are typically retained for a maximum of 14 months. Images you capture are processed on-device or transiently and are not stored on our servers unless you explicitly save them. You may request deletion of your data at any time (see "Account Deletion" below).

Data Security

We implement reasonable technical and organizational measures to protect your information against unauthorized access, alteration, disclosure, or destruction. These measures include encryption in transit (HTTPS/TLS), secure cloud infrastructure provided by Google Firebase, and access controls. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

Your Rights and Choices

Depending on your jurisdiction, you may have the following rights regarding your personal information:

Access: Request a copy of the information we hold about you.
Correction: Request that inaccurate information be corrected.
Deletion: Request deletion of your information.
Restriction or Objection: Restrict or object to certain processing activities.
Portability: Request a copy of your data in a portable format.

Opt Out of Tracking: Disable tracking in your device's settings at any time.

We will process your request within 30 days. Upon deletion, your personal data will be permanently removed from our systems, except for any information we are required to retain for legal, accounting, or regulatory purposes (such as transaction records).

International Data Transfers

Your information may be transferred to, processed, and stored in countries other than your country of residence, including the United States and other jurisdictions where our service providers operate. These countries may have data protection laws that differ from those in your country. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses to ensure your information receives adequate protection.

Children's Privacy

HantaScan is not directed to children under the age of 13 (or under 16 in certain jurisdictions). We do not knowingly collect personal information from children. If we become aware that we have collected personal information from a child without verifiable parental consent, we will take steps to delete that information promptly. If you believe a child has provided us with personal information, please contact us at diegoadriian6@proton.me.

California Privacy Rights (CCPA)

If you are a California resident, you have the right to know what categories of personal information we collect, request deletion of your information, and opt out of the "sale" or "sharing" of personal information as defined under the California Consumer Privacy Act (CCPA). We do not sell personal information in the traditional sense. To exercise these rights, contact us at diegoadriian6@proton.me.

European Privacy Rights (GDPR)

If you are located in the European Economic Area, United Kingdom, or Switzerland, you have rights under the General Data Protection Regulation (GDPR), including the rights of access, rectification, erasure, restriction, portability, and objection. The legal bases on which we process your data include your consent, the performance of a contract, compliance with legal obligations, and our legitimate interests in operating and improving the App. You also have the right to lodge a complaint with your local data protection authority.

Medical Disclaimer

HantaScan provides informational risk indicators only and is not a medical device, diagnostic tool, or substitute for professional medical, public-health, or pest-control advice. The App's scan results should not be relied upon to diagnose, treat, or prevent any disease. Always consult qualified professionals for medical concerns or for definitive assessment of hantavirus-related risks.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technologies, legal requirements, or other factors. When we make material changes, we will notify you by updating the "Effective Date" at the top of this Policy and, where appropriate, through an in-app notification. Your continued use of the App after the changes become effective constitutes your acceptance of the revised Policy.
