Suitability of the Services for children and parental
control tools

Modify this accordingly to suit if appropriate: The
Services are not directed at children under the age
of 13 and are not structured specically to attract
children under 13. Further, certain content that
you may access through your use of the Services
may contain material that you consider indecent,
objectionable or which may not be suitable for

children.

If you permit a child to use your LG Smart TV to
access the Services, you are solely responsible for
deciding whether or not the relevant Services are
appropriate for access by that child.

[Your Smart TV offers a parental control tool (by
way of a 4 digit PIN). If you have enabled the 4-digit
PIN, your LG Smart TV will not be able to display
restricted content unless you type in the PIN. You
are responsible for setting up and maintaining the
parental control tool and any other controls that are
available, and we will not be responsible for any harm,
loss or damage you suffer or any other user of your
LG Smart TV suffers as a result of your failure to do
so. Depending on the models of your LG Smart TV,
these features may not be available.

Viruses and Security

Modify this accordingly to suit if appropriate: We use
commercially reasonable efforts to ensure that the
Services are secure and virus free, but those efforts
cannot and do not guarantee that the Services will be
free from bugs, viruses, or other vulnerabilities.

or damage caused by a virus, distributed denial­of-service attack, or other technologically harmful
material that may infect your LG Smart TV, data or

other material belonging to you, during your use of

the Services.

relating to your use of the Services.

any or all of our rights and obligations under these
Terms of Use to any company, rm or person. We
can only do this if it does not materially affect your
rights under these Terms of Use. You may not assign,
sub-contract or otherwise transfer your rights or
obligations under these Terms to anyone else (except
where you dispose of your LG Smart TV to a third
party) unless you rst agree this with us in writing.

If we decide not to exercise or enforce any right that
we have against you at a particular time, then this
does not prevent us from later deciding to exercise or
enforce that right.

illegal, invalid or otherwise unenforceable by a court
or regulator, then, where required, that part shall be
deleted and the remaining parts of the Terms of Use
will continue to be enforceable.

These Terms of Use do not create or infer any rights
that are enforceable by any person who is not party

provisions.
