This Privacy Policy describes how the MedlinePlus mobile application ("App," "we," "us," or "our") handles information when you install and use the App on your device.

The App is designed primarily as an offline health reference. Most content—including symptom reference materials, medicine summaries, medical test descriptions, first-aid topics, and health library articles—is stored locally on your device after installation or first launch, so you can read it without a continuous internet connection.

Health information sources: portions of the reference library are informed by, summarized from, or organized using themes consistent with publicly available patient-education and consumer health information associated with MedlinePlus, a service of the National Library of Medicine (NLM), National Institutes of Health (NIH), United States. The official website is https://medlineplus.gov/ ("MedlinePlus.gov"). That site explains its mission, editorial policies, and how it handles information when you use it online.

Independence and attribution: this mobile application is not published, operated, or endorsed by the U.S. Government, NLM, or NIH. It is an independent product intended for offline convenience. For authoritative, current government health information and disclosures, use MedlinePlus.gov directly in your browser; when you do, that website’s own terms and privacy notices apply to your visit.

We do not operate user accounts inside this App. You are not required to register a name, email address, or phone number to access the core reference features described in the product description.

Data stored on your device may include: (a) reference content shipped with or downloaded into the App; (b) items you bookmark within the App, which are saved in the local database on your device; (c) preferences or settings the App stores to remember your choices between sessions; and (d) routine technical logs that the Android operating system may maintain for stability and diagnostics outside the control of this App.

Because bookmarks and similar interactions are stored locally, they remain on your device unless you clear application data, uninstall the App, or use device tools that remove App storage. Uninstalling the App typically deletes local App data unless your device manufacturer or backup tools copy it elsewhere.

The App is not intended to collect sensitive categories of personal information such as government identifiers, payment card numbers, or precise real-time location for advertising. If a future update introduces optional online features, this Policy will be revised to describe any new categories of data, purposes, and retention before those features are enabled.

If the App uses network access (for example, to check for updates, to open an external link you choose, or to load optional content), standard network operators and service providers may process technical metadata such as IP address, timestamps, and device type according to their own policies. We encourage you to review your device and carrier settings.

We do not sell your personal information in the sense of selling customer lists for cash. The App may display advertisements through Google Mobile Ads (AdMob). Google and its partners may use device identifiers, coarse location, and related signals to show and measure ads, as described in Google’s Privacy & Terms (https://policies.google.com/privacy). You can review and adjust ad personalization where available in your Android or Google account settings.

Security: we apply reasonable measures consistent with a local database application, including use of platform-recommended storage APIs. No method of electronic storage is completely secure; you should protect device access with a screen lock and keep your operating system updated.

Children: the App provides general health education. It is not a substitute for pediatric care. Parents and guardians should supervise use by minors. If you believe we have inadvertently collected personal information from a child in a way that violates applicable law, contact us using the details below so we can investigate and take appropriate steps.

International users: if you access the App from outside your home country, information on your device may be subject to the laws of the jurisdiction where the device is located. We do not intentionally transfer personal data across borders as part of core offline reading features.

Your choices: you may stop using the App at any time, adjust Android permissions in system settings, clear bookmarks inside the App where such controls exist, or remove the App entirely to delete locally stored data subject to your device behavior.

Changes to this Policy: we may update this text to reflect product changes, legal requirements, or clarity improvements. The "Last updated" line will be revised when material changes are made. Continued use after an update constitutes acceptance of the revised Policy unless applicable law requires a different process for consent.

Medical disclaimer: reference content is for educational purposes only and does not establish a clinician–patient relationship. It is not tailored medical advice, diagnosis, or treatment. Always seek qualified professionals for health decisions and emergencies.

Contact: for privacy-related questions about this App, please contact the developer or publisher email or support channel listed in the app store listing. Replace this sentence with your verified contact details before distribution if you are the publisher.

If you are a resident of a jurisdiction that grants specific privacy rights (for example, rights to access, correct, or delete personal information), and if we process personal information subject to those laws, you may exercise rights by contacting us as described above. Many features of this App operate without transmitting personal information to our servers.

Retention: locally stored bookmarks and preferences persist until you delete them or remove the App. We do not maintain a separate cloud copy of your bookmarks unless a future version explicitly states otherwise.

Third-party content and links: the App may reference or open external resources (including, for attribution, https://medlineplus.gov/). Third-party and government websites apply their own privacy practices and may collect data when you visit them. We are not responsible for third-party sites or applications you choose to visit.

California and other U.S. state notices: this App is structured to minimize collection of personal information. If you believe the App collects data that triggers a specific notice obligation in your state, contact us and we will respond in accordance with applicable law.

European Economic Area and UK: where the General Data Protection Regulation or UK GDPR applies, our lawful basis for any processing we describe is typically performance of a contract (providing the App), legitimate interests (security and product improvement where applicable), or consent where required. You may have rights to object, restrict, or port data; contact us to exercise those rights where they apply.

Complaints: you may lodge a complaint with a supervisory authority in your country of residence if you believe processing of personal data infringes applicable law.

Acknowledgment: by installing or using the App, you acknowledge that you have read this Privacy Policy and understand how information may be handled as described above.
