02Amendments

Moving is a change of address, not a new passport.

    NEVER CHANGES

    Your permanent ID. Apps and followers find you by it, wherever you live.

  2. FIELD 02 · ADDRESS
    pds.linkjar.social → any host you choose
    YOURS TO CHANGE

    Take your account and everything in it to another host. Your apps keep working.

  3. FIELD 03 · NAME

03Your data
