Terms of use

Last updated: 26 October 2026. The German version is the binding one.

In short

• Happicon is a game for everyone. Be fair and kind.
• No insults, no hate, nothing sexual or violent, no harassment. We have zero tolerance for that.
• You can report anything that bothers you and block players who annoy you.

Who provides Happicon

Happicon on happicon.app and in the Happicon app is provided by Robert Klinger (address in the imprint). These terms apply to everyone who plays Happicon. You accept them with your first own puzzle for friends or when you choose a player name.

The game

Happicon is free. You can play without signing up; for the daily puzzle and the friends mode the game creates a game account (see privacy). Coins, experience points and ranking points are game values with no monetary value. They cannot be paid out, sold or transferred to other accounts. We keep developing Happicon and may change, add or discontinue features.

Rules for names and puzzles

Other players see your player name, your emoji and your puzzles. So you must not publish anything that

• insults, threatens, harasses or belittles others, for example because of their origin, skin colour, religion, gender, sexual orientation, disability or age,
• shows or hints at sexual, pornographic or extremely violent content,
• glorifies extremist symbols, slogans or terror,
• reveals other people's personal data (such as real names, addresses or phone numbers),
• is advertising or spam or lures people to other offers,
• otherwise breaks the law or infringes the rights of others.

We have zero tolerance for objectionable content and for players who harass others. Also play fair: no second accounts to collect points, no tricks to read out answers and no attacks on the game.

Filtering, reporting, blocking

• Filter: we automatically check player names and puzzle titles for insults. Whatever fails cannot be saved. An AI also checks new names and puzzles; we reset or hide clearly unacceptable ones.
• Report: under every friend's puzzle, "Report or block" lets you report the puzzle or the player's name. You can also write to hello@happicon.app. We usually review reports within 24 hours.
• Block: if you block a player, your match ends and you can no longer play puzzles with each other. The other player is not told. You can undo this under "Me" → "Blocked players".

When three players report the same puzzle, we hide it right away; when three players report the same name, we reset it to "Spieler", in both cases until we have reviewed it. Content that breaks these rules is removed. For serious or repeated violations we may suspend or delete a game account. If you think we decided wrongly, write to us and we will take another look.

Your puzzles

Your puzzles belong to you. So that we can show them to your friends, including in link previews in chat apps, you grant us the simple, free right to store and display them for the game as long as your account exists.

Deleting your account

You can delete your game account at any time under "Me" → "Account" → "Delete account". That also ends this agreement.

Liability

We do our best to keep Happicon running but cannot guarantee it. We are fully liable for intent and gross negligence, for injury to life, body or health and under the German Product Liability Act. For slight negligence we are only liable for breaches of essential obligations and limited to the typical, foreseeable damage.

Changes and law

If these terms change materially, we will tell you in the game under "What's new?". German law applies; mandatory consumer protection rules of your country of residence remain unaffected.
