Terms of service
effective 1 November 2026. The deal between you and Wundr.
These terms govern your use of wundr.fun and the Wundr app (the "Service"), operated by Hitesh Goyal ("Wundr", "we"). By using the Service you agree to them. If you do not agree, do not use the Service. Our privacy policy explains what we keep about you and is part of these terms.
what the service is
A feed of small interactive programs, each made by a person, that you can play, keep, share and ask for more of. Some are games, some are lessons, some are just a feeling. We add, change, hold back and remove wundrs at our discretion, and the Service as a whole may change or end at any time.
who may use it
Anyone may play on the website without an account. To create an account you must be 13 or over, and you tell us the year you were born when you sign up. If you are under 18, you may use the Service only with the permission of a parent or guardian. You may hold one account. You are responsible for what happens under it: keep your sign-in codes to yourself, sign out of devices you no longer control, and tell us at hitesh@wundr.fun if you think someone else has used it.
what you may not do
Do not use the Service to break the law, to harm, harass or deceive anyone, or to post anything you have no right to post. Do not scrape, crawl, mirror or bulk-download the Service, its wundrs or its data other than through interfaces we publish for that purpose. Do not probe, overload, or work around limits and protections on the Service, create identities or accounts by automated means, or interfere with anyone else's use. Do not misrepresent who you are or who made something.
objectionable content and abusive people
There is no tolerance on Wundr for objectionable content or for abusive people. That means anything hateful, harassing, threatening, sexually explicit, gratuitously violent or otherwise abusive, in anything a person can put in front of someone else here: a handle, a catalogue's name and note, a comment, a request on the board, a room, or a wundr itself. Wundr is open to people from 13, so we also remove anything that is not suitable for people under 18.
How to report. In the app, every wundr has an information sheet (the i on the card) with "report" at the end of it, and reporting a wundr needs no account. A catalogue somebody created has a flag at the top of its page, and so does each person under find friends and each request on the board: it opens the same report, with a block for whoever is behind it. A comment: press and hold it, then report. From anywhere else, including this website, write to hitesh@wundr.funwith the link or the name.
What we do about it. A person on our team reviews every report. Content that breaks these terms is removed, and the account that posted it is ejected: its page and everything it made are taken out of view, and it is signed out everywhere. We do this without notice, and we do not tell anyone who reported them.
Blocking. In the app you can block any account from the same places you can report it. Neither of you is then shown the other's page or catalogues, and you stop following each other. The person is not told. You can see and undo your blocks from the You tab, under blocked people.
what you give us
Things you write or make on the Service, such as a wundr, a request, a handle, a catalogue you assemble, or a comment, are yours. You give Wundr a worldwide, royalty-free, non-exclusive licence to host, store, display, reproduce and adapt them in order to run, improve and promote the Service. That includes showing a wundr you post, and how it plays, in our videos, screenshots, ads and other promotion, in any medium, without payment. This lasts for as long as they are on the Service and as needed afterwards to keep public records like the request board coherent, and promotion made while a wundr was on the Service need not be withdrawn once it comes off. You promise you have the right to give that licence. We may edit for length, decline to list, hide, or remove anything you post, with or without notice, and we owe no explanation for an editorial choice.
what we give you
The wundrs and the writing on the Service are licensed to the public under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 licence, and the machinery that runs them under the Apache License 2.0, as set out in the repository's LICENSE file. That means you may fork a wundr with credit and share it alike, but not sell it or use it commercially without our written permission. Everything else, including the Wundr name, the kolam mark, the design of the Service and its catalogues, is ours or our licensors', and nothing in these terms transfers it. A wundr made by a person credits that person; the credit stays.
no warranty
The Service is provided as is and as available. To the fullest extent the law allows, we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy, and non-infringement. Wundrs are programs made by people and may contain mistakes; a wundr that describes a physical, medical, financial or legal idea is not advice. Some wundrs use flashing light, sound or motion; stop if you feel unwell.
limit of liability
To the fullest extent the law allows, Wundr and the people who make it are not liable for any indirect, incidental, special, consequential or punitive damages, or for lost data, profits or goodwill, arising from the Service, however caused. Our total liability to you for anything arising from the Service is limited to the greater of the amount you paid us in the twelve months before the claim and one thousand Indian rupees. Where the law does not allow a limit, it applies to the extent it does.
indemnity
You will defend and hold Wundr harmless from claims, losses and reasonable costs arising from what you post on the Service or your breach of these terms.
ending things
You can delete your account at any time from the You page. We may suspend or end your access, remove your content, or block a device, if we reasonably believe these terms or the law have been broken, or to protect the Service and the people on it. The sections on what you give us, what we give you, no warranty, limit of liability, indemnity and law survive.
law and disputes
These terms are governed by the laws of India. Any dispute will be brought only in the courts of Surat, India, and you consent to their jurisdiction. Before filing anything, write to hitesh@wundr.fun; most things are fixable in a message.
changes
We may change these terms. When a change matters, the date at the top changes, and if you have an account we will tell you before it takes effect. Using the Service after that date means the new terms apply. If any part of these terms is found unenforceable, the rest stands. These terms are the whole agreement between you and Wundr about the Service.
