A podcast title can reveal more than a person expects. Recent searches and listening lists may relate to health, family, beliefs, or private interests. A shared tablet or family browser therefore deserves careful defaults.
Begin by listing surfaces that show personal activity outside the main library. Notifications, browser titles, home-screen widgets, lock-screen controls, and account-switch previews can all expose context.
Decide what belongs in each surface
A public show page can show ordinary catalog data. A “because you listened” explanation or private history list has a different audience. Keep those distinctions in your component and cache design.
Let people understand and control history-related features that your app actually provides. Do not promise a private mode unless its network requests, logs, local state, and notifications follow the same policy. A hidden history panel alone does not change how events are stored.
Use clear account names in account switching, but avoid filling a public notification with unnecessary listening details. On sign-out, clear private previews and stop in-flight responses from restoring the previous person's state.
Review a real shared-device journey
Sign in, search for a sensitive topic using a test account, open an episode, and switch accounts. Check back navigation, app restoration, and any notification preview. Then repeat without network access.
Ask whether each remaining label is public catalog context or personal activity. That question is easier to apply than a broad statement that all podcast data is harmless.
Your privacy notice should describe the behavior you ship. Podnivo's workspace isolation is one technical boundary; careful presentation on a shared device is another boundary owned by your application.
