Comment:

 I agree to comment:3. Settings shouldn't be saved just because I preview
 something. `get_option()` supports a third parameter to define a default
 value, which should have in your case the same value as after a theme
 activation.

 There is also an action `start_previewing_theme`![1] and you can use
 `$wp_customize->is_preview()`![2].
