I haven’t any privacy by this app ??? – Telegram Messenger Review

Why you don’t make more privacy for this app???? Why everyone who has my phone number, could save me on telegram and send messages?? And see my profile picture???? But in WhatsApp we have an option that is about who could see my photos, and who could send messages to me, and I can manage it as just my contacts, so if I have not save stronger phone numbers in my phone, they can’t make disturb me, please you also make such as this good privacy option ?
