On Android, simply slide out the left menu and choose New Secret Chat to start a new one. On iPhone, open a chat, tap the contact's name at the top, choose More, and then hit Start Secret Chat.

However, you can choose to get rid of the old sessions sooner in order to further boost security.

While you can receive/send files irrespective of their type and size, you can disable automatic media download and auto-play media to save mobile data. This way, you can also avoid downloading unnecessarily large files. If you select the Scheduled option, the auto-night mode will kick in at a pre-defined time which you can change.

You can slide the slider to select at what percentage of the ambient lighting do you want the night mode to start at. Personally, I prefer the scheduling option, however, you can use the one you like.
