What happens if I have to reinstall Telegram. Is the data preserved?

Telegram does not save the chats (including images and videos) locally on the smartphone, but in the cloud. Therefore - in contrast to e.g. Whatsapp - no manual data backup is necessary. Telegram can assign all data, settings, etc. based on the phone number and automatically restore them when the smartphone or the Telegram app is reinstalled. Provided that the telephone number has remained the same, all that is required is a new registration with the old telephone number. If, contrary to expectations, it does not work, the ProfitWallet data is of course also secured on our servers. Telegram is just the UI to display the balance value and the other buttons.
