Another great option in groups or channels is being able to pin messages. Tap a message and choose Pin to keep it at the top of the chat, where everyone can easily reference it. There's also a hidden menu that appears when you long-press on the Send button. Choose Schedule message to delay sending until a time in the future. You can also tap Send When Online to send the message when the other person is next active on Telegram. These new monetization methods include ads on public one-to-many channels (which function like Twitter feeds), premium features for business teams and power users, and paid sticker packs. Some of these funds will go back to users in the form of enhanced visibility for channels or payments to creators of unique sticker packs.

The Bot API is a free and open platform, available to everyone. If you're looking to build your own bot, check out this page. Telegram is a multi-platform messaging service founded by Russian entrepreneur Pavel Durov, although it was temporarily banned in Russia and has no affiliation with any government or company. It first rolled out on iOS and Android in late 2013, and now has an estimated 550 million monthly users. Telegram’s user base tends to increase whenever a privacy scandal hits one of its larger competitors. Since Telegram stores chats and files on a remote server instead of your device, you can also access everything (except secret chats) from the web. Access it via the web portal or any of several Chrome extensions. Do you enjoy using both light and dark modes? Telegram has an auto-night feature so the app doesn't blind you at night.

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. The cool features of Telegram aren't all so serious, though. Check out how to make your own Telegram stickers if emojis aren't enough. Take Control of Telegram Privacy and Security 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.

That’s far from saying Telegram will protect you from all privacy terrors the online world presents — you should check out our Android privacy guide for a broader look at that. Telegram just offers a good marriage of popularity and security for those with concerns over other messaging apps. Telegram offers two types of APIs for developers. Both are free of charge.
