When it comes to Telegram files on your Mac, they will be saved in a few locations. Most are in the following location: ~/library/Group Containers/6N38VWS5BX.ru.keepcoder.Telegram. If you want to delete things, you can move them from that folder to the trash, or you can delete downloaded items from the downloads folder.
By default, Telegram saves files on a PC according to the following file path: C: > Users > [Your Username] > AppData > Roaming > Telegram Desktop. If you want to delete any files, you can do it manually in the “Telegram Desktop” folder. You can also automatically manage Telegram files through the app’s settings.
You can control how Telegram stores files on your iPhone through the Telegram settings. Within those settings are controls for storing data, clearing out data, automatic downloads, and the location for local storage. Finding and deleting Telegram files on your iPhone all happen within these settings.
Telegram saves files on an Android device at this specific folder destination: /storage/emulated/0/Android/data/org.telegram.messenger/files/Telegram. If you want to delete files from this folder, you can do that manually using the File manager on every Android device. Or, clear the cache from within the Telegram app.
Telegram is about as safe from governments as an internationally available communication platform can be. Telegram uses multiple layers of digital security combined with strategic practices that make it virtually impossible for governments to forcibly take personal data from the Telegram servers. No application is ever 100% secure, though.
Telegram is hands down one of the safest apps on the internet for communicating and sharing files. While nothing can ever offer perfect protection in all ways, Telegram downloads are much safer than average, when compared to the internet at large. The company takes safety and privacy to a whole new level.
