Terms of Use

Last updated: August 26, 2026 · Effective: August 26, 2026

These Terms of Use (“Terms”) govern your access to and use of zoggle.io and its content (the “Site”). By using the Site, you agree to these Terms. If you do not agree, please do not use the Site. Zoggle is an independent project operated by an individual (“we”, “us”).

1. The Site

Zoggle provides a free daily estimation game and related written content, offered for entertainment and educational purposes. We may change, suspend, or discontinue any part of the Site at any time, including the daily puzzle schedule, without notice or liability. We do not guarantee that the Site will be available without interruption or free of errors.

2. Eligibility

The Site is intended for a general audience. It requires no account and collects no personal information, but if you are under the age of majority where you live, you should review these Terms with a parent or guardian.

3. Permission to use the Site

Subject to these Terms, you may access and use the Site for your own personal, non-commercial enjoyment. You may share links to the Site freely, and you may share your own results — that is the point of the share feature.

4. Intellectual property

All content on the Site — including the questions, answers, worked examples, explanatory writing, source selections, page copy, the Zoggle name and logo, the visual design, and the underlying code — is original work owned by us and protected by copyright and other laws. Estimation as a game concept is free for anyone to use; this particular expression of it is not.

Except as permitted above or by law (such as brief quotation with attribution and a link), you may not copy, reproduce, republish, distribute, sell, or create derivative works from Site content without our prior written permission. In particular, you may not scrape, crawl, bulk-download, or systematically extract the question archive, whether manually, by automated tool, or to train machine learning models. You may not remove or obscure any copyright or attribution notice.

5. Acceptable use

You agree not to:

• Interfere with, disrupt, overload, or attempt to gain unauthorized access to the Site or its infrastructure
• Use automated systems to access the Site in a way that sends more requests than a human reasonably could
• Introduce malware, or attempt to probe, scan, or test the vulnerability of the Site
• Misrepresent your results as official rankings or imply endorsement by or affiliation with Zoggle
• Use the Site for any unlawful purpose or in violation of these Terms

Looking up answers before guessing is not a violation of these Terms — it is simply a waste of your own time.

6. Question suggestions and other submissions

We welcome question ideas, corrections, and feedback. If you send us a submission, you grant us a perpetual, irrevocable, worldwide, royalty-free, non-exclusive license to use, adapt, publish, and distribute it on the Site and in related materials, in any medium, without compensation. You represent that your submission is your own or that you have the right to share it, and that publishing it will not infringe anyone's rights.

We are not obligated to use any submission, to keep it confidential, or to return it. Where we use a suggested question, we will credit the submitter unless they ask otherwise. Similar ideas reach us independently, so a submission does not create any exclusivity or claim of ownership over a published question.

7. Accuracy of content — important

Zoggle's answers are researched from public sources cited on each reveal, but real-world figures change over time, are revised by their publishers, and are sometimes disputed between reputable authorities. The game scores by orders of magnitude, so approximate answers are sufficient for play and are not represented as precise or authoritative.

Do not rely on Site content for any consequential decision, including financial, medical, legal, engineering, safety, or academic purposes. Content is provided for entertainment and general interest only. If you spot an error, please tell us at hello@zoggle.io.

8. Third-party content and links

The Site cites and links to third-party sources and websites. We do not control and are not responsible for their content, accuracy, availability, or practices, and linking does not imply endorsement.

9. Advertising

The Site may display third-party advertising in the future. We do not endorse advertised products or services and are not responsible for advertisers' content, offers, or conduct. Dealings with advertisers are solely between you and them.

10. Disclaimer of warranties

THE SITE AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SITE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT ANY CONTENT IS ACCURATE OR CURRENT. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SITE, WHETHER BASED IN CONTRACT, TORT, OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SITE WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100). This includes, for the avoidance of doubt, loss of your locally stored streak or game history. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

12. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your misuse of the Site, your violation of these Terms, or your violation of any law or third-party right.

13. Copyright complaints

We respect intellectual property rights. If you believe content on the Site infringes your copyright, email hello@zoggle.io with: identification of the work claimed to be infringed; identification of the material and its location on the Site; your contact information; a statement of good-faith belief that the use is unauthorized; a statement, under penalty of perjury, that your notice is accurate and that you are the owner or authorized to act on the owner's behalf; and your physical or electronic signature. We will respond promptly to valid notices.

14. Termination

We may restrict or terminate access to the Site, in whole or in part, at any time and for any reason, including violation of these Terms. Sections 4, 6, 7, and 10 through 16 survive any termination.

15. Governing law

These Terms are governed by the laws of the State of [YOUR STATE], United States, without regard to its conflict-of-laws rules. You agree that any dispute arising from these Terms or the Site will be brought exclusively in the state or federal courts located in that state, and you consent to their jurisdiction. Nothing here deprives you of the protection of mandatory consumer laws of your country of residence.

16. General

These Terms are the entire agreement between you and us regarding the Site. If any provision is found unenforceable, the remainder stays in effect. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a transfer of the Site.

17. Changes to these Terms

We may revise these Terms from time to time. Revisions take effect when posted here with an updated date, and your continued use of the Site constitutes acceptance. If you disagree with a revision, stop using the Site.
