You are in complete control of your photos. You can choose to have your photos hidden to all members.
You can then choose to reveal your photos to a specific match at a time of your choosing (in the Chat tap […] and tap Reveal photos).
Once unmatched or blocked your photos revert back to being hidden automatically.
Both are optional however and are not recommended. Profiles with Visible photos receive 300% more matches and are unmatched less.
To change your Photo privacy go to ⚙️Settings → Go to Privacy → Hide my photos & videos and toggle the option.
