Core app data
- Articles and reading progress: stored locally so saved and in-progress reads remain available in the app.
- Preferences: stored locally for settings such as theme, focus assist, discovery topics, and trusted sources.
- Optional API key: stored locally if you choose to provide one for AI-backed features.
Discovery data
Smoothie stores local discovery candidates, recommendation reasons, and local ranking state so it can populate the “For you” shelf. Discovery topics and trusted sources are used to shape this feed.
Imported and shared content
When you import a file, use clipboard import, open a shared item, or generate an article from search, the app processes the content you provided so it can clean it, save it, and prepare it for reading.
AI-assisted processing
Some Smoothie features depend on external AI processing. Depending on the feature and configuration, the app may send article text, selected terms, excerpts, summaries, or a user-entered prompt to a network service to generate:
- inline smoothing of dense terms
- intent classification
- unified reading structures
- search-generated reading content
Network requests to content sources
Smoothie makes ordinary network requests to webpages, feeds, and linked article sources to fetch content for import and discovery. Those external sites may receive standard request metadata such as IP address, request headers, and timing information as part of the request.
Data sharing boundaries
- Smoothie does not present itself as a data broker.
- Smoothie does not use your content for in-app advertising profiles.
- Data may still be processed by third-party providers when you use network-backed AI or content retrieval features.
User control
- You can delete saved articles inside the app.
- You can disable focus-assist prompts in settings.
- You can clear app storage or uninstall the app to remove local app data from the device.
- You can choose whether to provide an optional API key.
