Privacy Policy

EPIC — NASA Image Viewer

Last updated: April 2, 2026

Simple Summary: EPIC does not collect, store, transmit, or share any of your personal information. All data stays on your device.

Information Collection and Use

EPIC is designed with your privacy in mind. We do not collect any personal information from users of the app. EPIC does not use third-party analytics or advertising SDKs.

NASA API Usage

EPIC fetches publicly available data from NASA's open APIs, including the Astronomy Picture of the Day (APOD), NASA Image Library, and EPIC Earth imagery. These requests are made directly to NASA's servers over HTTPS. No personal information is sent with these requests beyond what is standard in an HTTP connection (such as your IP address, which is handled by NASA's servers according to their own privacy policy).

NASA TV Streaming

EPIC can stream live NASA TV broadcasts. The app fetches a small configuration file from our servers to obtain current stream URLs. This request contains no personal data — only a standard HTTPS fetch. The video streams are served directly by NASA's content delivery network.

Data Storage

The app stores the following data locally on your device only:

Your favorited images (stored via Apple's SwiftData framework)
Cached images for faster browsing (stored in the app's temporary cache)
Cached NASA TV stream URLs (stored via Apple's standard UserDefaults)

This data never leaves your device and is not accessible to us or any third parties.

Downloads

When you download images, they are saved to your device's Downloads folder (Mac) or through the system Files picker (iPhone and iPad). Downloaded files remain entirely under your control and are not tracked by the app.

No Analytics or Tracking

EPIC does not use:

Analytics services
Crash reporting tools
Advertising networks
Tracking technologies
Third-party SDKs that collect data

No Account Required

EPIC does not require you to create an account, provide an email address, or share any personal information to use the app.

Children's Privacy

Because we do not collect any information, our app is safe for users of all ages, including children under 13.

Data Security

Since no personal data is transmitted from your device to our servers, there is no risk of data breaches or unauthorized access to your information through our app. All network communication uses HTTPS encryption.

Your Rights

You have complete control over your data:

Access: Your favorites and cache are stored locally and never shared
Deletion: Simply delete the app to remove all local data
Downloads: Files you download are saved to standard system locations you control
Control: You can remove individual favorites at any time within the app
