ClanBoard is free and open. Using it means accepting these few lines.
You need a Telegram account, with the minimum age Telegram asks for, and to manage a clan a village linked with the game token. One bot per clan, one clan per group.
No spam, scams, harassment or illegal content in the texts the bot publishes; no attempts to get around the limits or to enter where you should not; no use of the game data outside the Supercell terms.
It is free and without warranty: it can stop, get a count wrong or skip a round, and the game data is worth what the official API is worth. There is nothing to pay and nothing to unlock.
A bot used for harassment or scams is suspended and the clan can be removed. On the other side, the clan leader stops whenever they want: remove the bot from the group and that is the end of it.
If these lines change, the date below changes too.
The code is under the AGPL-3.0 licence: you can read it, change it and run it yourself, under the same conditions.
