Edit map only for me

Hello, can I edit my only for me, not to website?

hi, maybe something like umap, to make your own map?

Welcome to this forum, Milosz! What you require is basically contrary to the primary intention and mission of openstreetmap: the goal is to create a database of geographical information for all. Creating a map from that database is a second matter, the default map is just one example of that. Read more about it at https://wiki.openstreetmap.org/wiki/Standard_tile_layer . But there are many ways of consulting the database, and it is quite possible that the umap thing mentioned does what you are looking for; there may well be others, too.
