A used television or player can retain account profiles, browsing history and app sessions. Remove personal data through the device's documented process before transfer. A factory reset and server-side account revocation address different parts of the exposure.
Sign out deliberately
Use app sign-out or profile-removal controls first where available. Check other installed services too, not just the main player. Disconnect external storage and remove personal files that are not covered by an app logout.
Follow the device reset guidance
A supported factory reset can remove local configuration, but behaviour varies by platform. Read the manufacturer's instructions and verify the resulting setup screen. Do not assume that unplugging the device erases saved credentials.
Review remote access
If the service offers session or device management, remove the transferred device there as well. Ask the provider about credential replacement if sensitive account data may remain exposed. Keep the new owner from receiving your private playlist link.
