Nimbus Shield Privacy Policy

Nimbus Shield is a privacy-focused migraine tracking application for Android developed and operated by Zymric.

This Privacy Policy explains how information is stored, processed, transmitted, protected, and disclosed when you use the Nimbus Shield Android application.

This Privacy Policy applies only to the Nimbus Shield Android application. It does not apply to the general Zymric website, other Zymric products, or services governed by a separate privacy policy.

Your health records belong to you. The health information you enter into Nimbus Shield is stored on your device and is not uploaded to or stored on Zymric’s servers.

Nimbus Shield does transmit limited technical, purchase, analytics, crash-reporting, and location-request information to the third-party services described in this policy. These transmissions do not intentionally include your migraine records, journal content, medication details, symptoms, triggers, menstrual-cycle entries, or exported reports.

Nimbus Shield is operated by Zymric.

For privacy questions, requests, or complaints relating to Nimbus Shield, contact us at zymricc@gmail.com.

Nimbus Shield stores the information you enter into the application in a local database on your Android device.

Depending on the features you use, this information may include migraine or headache episode data, pain intensity, symptoms, triggers, medication details, daily check-ins (sleep, stress, hydration, exercise), menstrual-cycle information, journal entries, reports and insights, application preferences, saved location coordinates, and notification settings.

This information is used to provide Nimbus Shield’s tracking, reporting, correlation, reminder, and personalization features.

Zymric does not operate a Nimbus Shield account system or cloud database for these health records.

A locally entered name or display name may appear in reports you generate. Zymric does not receive this name unless you voluntarily include it in a support request or exported report.

Nimbus Shield does not require you to create an account. Zymric does not intentionally request your email address, telephone number, contact list, photos or media library (except through Android’s system file picker), camera access, continuous location tracking, or payment-card details.

Nimbus Shield does not contain advertising SDKs or third-party advertising networks. Zymric does not sell your health information or use it for targeted advertising.

Although health records remain on your device, certain Nimbus Shield functions rely on third-party service providers. Limited information may be transmitted for weather data, anonymous product analytics, crash reporting, purchase verification, and support communications.

Nimbus Shield uses Open-Meteo for weather information (sending coordinates and standard request metadata), PostHog Cloud US for anonymous product analytics (usage events, no health data), Firebase Crashlytics for crash and diagnostic reporting (technical data only), Google Play Billing and RevenueCat for purchases and subscriptions (transaction records, no payment-card details), and an email provider for support communications.

Each provider processes information under its own privacy terms. Nimbus Shield does not intentionally send these providers your health records, journal content, medication details, or exported reports.

When you enable weather-related features, Nimbus Shield requests permission to obtain your device’s approximate location and uses the coordinates to retrieve weather information. Nimbus Shield does not use background location tracking or continuously monitor your movements.

Nimbus Shield may use Android notifications for reminders, check-ins, or reports you choose to enable. Notification preferences are stored locally. You can disable notifications through the application or Android system settings.

Nimbus Shield allows you to export your information in JSON, CSV, or PDF format. Exports are generated on your device and passed to Android’s system sharing interface. Zymric does not automatically receive or store your exported files.

After an export leaves Nimbus Shield, it may be stored or processed by whatever application, service, or recipient you select. Zymric cannot control, retrieve, or delete copies held by others. Exports may contain sensitive health information, so review your destination carefully before sharing.

Nimbus Shield uses security safeguards including Android private application storage, encryption of sensitive local information, HTTPS or TLS for network communications, and minimization of data sent to third-party providers.

No method of storage or transmission is completely secure. The security of locally stored information also depends on the security of your Android device. You should protect your device with a screen lock and keep Android security updates current.

Locally stored health information remains on your device until you delete it, clear the application’s data, or uninstall Nimbus Shield.

Information held by third-party providers is retained according to their respective policies for purposes such as subscription administration, accounting, crash resolution, and legal compliance.

Information processed through Nimbus Shield and its service providers is used only as reasonably necessary to provide the application’s features, store and display your entries, generate reports and insights on your device, retrieve weather information, maintain subscription access, understand general usage, improve performance, diagnose crashes, respond to support inquiries, prevent fraud and abuse, and comply with legal obligations.

Zymric does not use your health records for advertising.

You can edit or delete individual records within Nimbus Shield, or clear all data through Settings > Data Management > Clear All Data. Uninstalling the application also removes locally stored records.

Deleting local information does not automatically delete files you previously exported, copies held by recipients, Google Play or RevenueCat purchase records, analytics events or crash reports already transmitted, server logs from Open-Meteo, or support emails.

To request deletion of information controlled by Zymric, contact zymricc@gmail.com. Zymric may retain information where required by law or reasonably necessary for fraud prevention, security, accounting, dispute resolution, or legal claims.

Nimbus Shield provides the following choices: edit or delete local entries, export data, clear all data, disable analytics in Settings, disable location permission, stop using weather features, disable notifications, or uninstall the application.

Depending on where you live, you may have rights including the right to access, correct, delete, or export your data; restrict or object to processing; withdraw consent; and lodge a complaint with a privacy authority.

To submit a privacy request, email zymricc@gmail.com with the subject line “Nimbus Shield Privacy Request”. Zymric may need to verify your request. Because Nimbus Shield does not use accounts, Zymric may be unable to associate anonymous technical data with you unless you provide relevant identifying information.

Nimbus Shield is not intended for children under 18 (or the legal minimum age in your country). Zymric does not knowingly request personal information from children below this age. If you believe a child has provided information to Zymric, contact zymricc@gmail.com.

Nimbus Shield is a self-tracking and informational tool. It is not a medical device and does not provide medical advice, diagnosis, treatment, emergency monitoring, or a substitute for consultation with a qualified healthcare professional.

Reports, correlations, and insights generated by Nimbus Shield may be incomplete or inaccurate. Do not begin, stop, or change medication based solely on information displayed by Nimbus Shield. If you believe you are experiencing a medical emergency, contact your local emergency services immediately.

If Zymric becomes aware of unauthorized access to information processed by Zymric or its service providers, Zymric will investigate, take reasonable steps to contain and remediate the incident, and provide legally required notifications where applicable.

Zymric may update this Privacy Policy to reflect changes to Nimbus Shield, new or removed service providers, changes to information practices, or legal or regulatory requirements. The updated policy will display a revised “Last Updated” date.
