Custom fields WordPress update

hi,

planning on using a lot of meta data (custom fields) for my (post/custom_post_types/page/user) . concern about wordpress/plugin updates.

ex:
post_type_1 => [price][location][availability]
user => [phone][address]

something like that.

is it possible that i might loose these data on updates ?
.. if yes, is there anyway i can prevent updates from removing/deleting/altering my meta data

thank you

not sure if this is the right section
