In a local database tied to the playlist profile you are logged into, not in your subscription. That is the key fact, and it explains behavior people find confusing. The recently watched row in Live TV, and the continue watching row for movies and series, are drawn from that database. Favorites are stored the same way but populated deliberately by you. Because the store is per profile and per device, the phone keeps its own record and the television keeps another, and deleting one does nothing to the other. It also means signing out and back in with identical credentials does not necessarily clear anything, since the profile record can survive the logout.

1. 1History is per device and per playlist profile
2. 2Favorites are a separate list from recently watched
3. 3Logging out is not the same as removing the profile

Start narrow. On most builds, holding the select button or long-pressing an entry in the recently watched or continue watching row brings up a remove option for that single item; on a remote, the equivalent is press and hold on the tile. Favorites are removed the same way you added them, by opening the channel and toggling the favorite marker off. Do this first because it is reversible and costs nothing. Only if the app offers no per-item removal on your build, or the list is long enough that item-by-item is impractical, should you move on to clearing the profile or the app data, both of which take other settings with them.

No. Your subscription lives on the service side and consists of Xtream Codes credentials, so clearing app data or reinstalling the app removes only the local copy of your lists and settings. Installs are unlimited, there is no per-device charge and nothing needs to be released or deactivated first. Re-entering the username, password and server address takes about five minutes plus one slow first load while categories and guide data rebuild. What you do lose is worth knowing in advance: hidden category selections, favorites, parental lock settings and any per-channel preferences all go with the data. Note which groups you had hidden before you clear anything.

1. 1Credentials are server-side, so nothing about the plan is affected
2. 2You lose favorites, hidden groups and parental settings too
3. 3Expect one slow catalog load after re-entering the login

Three things. Other devices keep their own records, so a household with the same login on four devices has four separate lists to handle. Your internet provider still sees that connections were made, and a VPN would hide traffic from that provider while changing nothing about how content is licensed. And a shared plan running 1 to 5 simultaneous connections gives everyone the same credentials, which means separate playlist profiles or separate devices are the only practical way to keep viewing lists apart within one household. If the goal is privacy from other people in the house rather than tidiness, use the parental lock on categories as well as clearing the list.
