Group Voice chats Premium Chat Management To find more themes, Android users can try the Themes for Telegram app. If you use an iPhone, have a look at the Telegram Themes subreddit. To do this, long-press on a picture you have sent. Choose the ‘Edit’ button on the top, just like you’d edit a text message once you have sent it. Now, you will get an in-built photo editor where you can add filters, draw or crop images. Alternatively, you can even replace the picture and send another one in its place.

Self Destruct Messages on Secret Chats Telegram allows you to manage the device storage: you can choose to delete media (photos, videos, and other files) shared on the app. All files will be deleted from your device after the specified duration, but they will stay in the Telegram cloud forever, so you can re-download them when you need them again. There is also an option to delete the cache and local database. How does Telegram work? Another thing to keep in mind is that selling your data isn’t at the core of Telegram’s business model. According to Telegram’s FAQ page, the company is funded by its founder and CEO Pavel Durov, not through advertising or data collection and sharing.

Terminate old sessions If you don’t want messages in your secret chats to hang around forever, Telegram lets you set self-destruct timers to permanently remove them. After a message is received, it remains in the chat for a predetermined period — you can choose times between one second and one week – before disappearing.
