Bot Privacy Policies

Bots and mini apps must comply with all applicable privacy laws and regulations – including those from Apple and Google stores.

To remain in compliance with Apple guideline 5.1.1 (i), bots and mini apps must provide a Privacy Policy detailing what data they store, how they collect it, and for what purpose.

Operating without a separate Privacy Policy will lead to suspension or termination of your bot on Telegram.

Mini apps can make their Privacy Policy easily accessible by including a link to it on a 'Settings' page, while bots must make it available via the /privacy command.

For more information about these requirements, please see this section of the Bot Developer Terms of Service.

? Join TypeScript Global Summit'24 and watch a talk about the magic behind filter queries!

Since filter queries were introduced in the first commit of grammY, they have proven to be an innovative step forward. Their power and flexibility can hardly be matched by other abstractions even to this day. Much of their complexity lies in the sophisticated type inference that has an accurate understanding of the Bot API. It recursively analyzes your code many layers deep and asserts that the right properties are present under the right conditions. It was a challenge to get these types right, and it was an even greater challenge to make type inference fast. How did we do it?

This talk will extract the most important lessons learned in the past three years, and teach you what you should avoid if you care about fast compilation times in TypeScript.

Buying a ticket to the conference will grant you access to several other in-depth talks about TypeScript. Oh, you don't want to pay?

There is a second talk related to grammY that focuses on getting developer experience right, and you can watch it for free! Register now »

*? Release of grammY 1.23 ?***This update brings support for the recently released Telegram Bot API 7.3.

As always, there are a few minor fixes and improvements. A small but noteworthy change is the introduction of ctx.chatId, an alias for the chat identifier from the current update.

*? Release of grammY 1.22 ?***This update brings support for the recently released Telegram Bot API 7.2.

Apart from a few minor fixes and improvements, this release finally solves a long-standing problem related to very slow compilation times when certain filter queries were used. Microsoft implemented a performance improvement in the TypeScript compiler in order to help with this, and the types in grammY itself were streamlined to match this. As a consequence, this release adds more than 330 new filter queries while still providing faster type inference than before.

Today, we are launching tools.grammy.dev, a dedicated website for useful tools around bot development ? Currently, it contains two tools already, with more to follow in the coming time. The first tool is our Update Explorer. You can watch Telegram updates…

*? Release of grammY 1.21 ?***This update brings support for the recently released Telegram Bot API 7.1.
