Hi, @gardenhm
Welcome!
I appreciate your inquiry on using a Roku device in a rental property, and I'm here to guide you with information regarding this matter.
As advised by @JWS9518, Roku has a feature called "Guest Mode." In Guest Mode, you can sign into your own apps to watch your content. On a date that you select, you are automatically signed out and your information is deleted. Guest Mode provides peace of mind that your viewing history remains private and all your accounts are secure.
To learn more, you can visit this support article on How to use Guest Mode on a Roku streaming device
I hope this information helps, and let us know if you have further questions or clarifications.
Thanks,
Roku Community Team.
