Terms of Service

Effective date: October 5, 2026

These terms are an agreement between you and Datacleave Ltd, a Canadian federal corporation ("Datacleave", "we", "us"). They cover dupefont.com, its API and the Dupefont app for ChatGPT (together, the "Service"). By using the Service you accept these terms and our Privacy Policy. If you don't accept them, don't use the Service.

If you use the Service for a company or other organization, you accept these terms on its behalf and confirm that you have the authority to do so. In that case "you" includes the organization.

Who can use the Service

You must be at least 13 years old, or the age of digital consent where you live if that is higher. If you are under the age of majority where you live, you may use the Service only with the permission of a parent or guardian. Don't create share links or tick "keep this image" if you are under 14 and live in Quebec, or under 16 and live in the European Economic Area or the United Kingdom. You may not use the Service where the law prohibits it, including where Canadian, US or United Nations sanctions prohibit it.

What the Service does

Dupefont suggests free and open-source fonts that look similar to a font file, a font name or text in an image you provide. We may change the Service, add or remove features, introduce paid features, limit how much you can use it, or stop offering it, at any time and without notice. We don't promise that the Service will be available, fast or free of errors, and we don't offer any service level or uptime commitment.

Results are estimates

Matches are produced automatically by comparing letter shapes and font measurements. They are suggestions, not facts. A match, a percentage score or a label such as "likely the same font" does not mean that two fonts are the same, that one is a legal substitute for another, or that a font identified from an image is the font that was actually used. Check a font yourself before you rely on it, especially for printed, commercial or brand work.

Nothing on the Service is legal advice. In particular, statements that a free font is "metrically compatible" with, or "an alternative to", a commercial font describe how the fonts look and measure. They are not advice about copyright, trademark or licensing.

Fonts, font licenses and trademarks

The fonts we suggest are made by other people and organizations. We don't own them and we don't grant you any license to them. Font files are not part of the Service. Where we let you download a font file or link to Google Fonts, we do so for convenience only: each font is provided under its own license (for example the SIL Open Font License or the Apache License), and that license, not these terms, decides what you may do with the font. You are responsible for reading and following the font license before you use a font. License labels on the Service are provided for information and may be wrong or out of date.

Names of commercial fonts, such as Helvetica, Futura or Gotham, and the names of companies and brands, are trademarks of their owners. References to them identify the fonts people search for. Their owners have not endorsed Dupefont and we are not affiliated with them. Descriptions of commercial fonts and their designers may contain errors.

Your content

"Your content" means the images, font files, text, ratings, feedback and other material you submit. You keep any rights you have in it. You confirm that you have the right to submit it and that submitting it, and our use of it as these terms describe, does not break the law or infringe anyone else's rights, including copyright, trademark, privacy and publicity rights. Don't submit images that contain other people's personal information unless you are allowed to share it.

You give us a worldwide, non-exclusive, royalty-free license to host, copy, process, analyse and transmit your content to run the Service, to keep it secure and to fix problems.

If you create a share link, you make your image, the text we read in it and its matches public to anyone who has the link. You give us a worldwide, non-exclusive, royalty-free license to store, reproduce, display, resize and distribute that material on the share page, in link previews and in our backups. We may provide a way to delete a share, and we may delete or expire shares at any time. We may keep copies where the law requires it. Anyone you send the link to can copy what they see, and we can't undo copies made before you delete it.

Feedback and images you let us keep

If you send feedback, ratings, reports or suggestions, we may use them for any purpose without paying you or owing you anything. If you tick the box that lets us keep an image you send with feedback, you also give us a worldwide, non-exclusive, royalty-free license to store, copy, modify and use that image to test, evaluate and improve our matching, including to tune or train our matching models. Our hosting and service providers may handle it on our behalf. Deleting the image doesn't affect models, measurements or statistics we produced from it before deletion.

Acceptable use

You agree not to:

submit content that is illegal, infringing, defamatory, sexually explicit, hateful, or that exploits or harms minors;
use share links for phishing, impersonation, spam, search-engine manipulation, malware, other people's personal information or anything that has nothing to do with identifying fonts;
use bots, scrapers, crawlers, headless browsers or AI agents to access the Service, other than the API and the official Dupefont app for ChatGPT, or ignore our robots.txt;
copy, extract, store or cache the Service's content or results in bulk, by any means, including through the API;
use the Service, its content or its results, including through the API, to build, train, fine-tune, evaluate or benchmark any machine-learning model, dataset or database, to use them as prompts or inputs for such models, or to build a product or service that competes with Dupefont;
get around rate limits, access controls or other technical restrictions, or use several identities or addresses to do so;
overload, disrupt, probe or attack the Service or the systems it runs on;
decompile or reverse engineer the Service, or try to work out its source code, models, rankings or data;
present the Service or its results as your own, or suggest that we endorse you or your work;
use the Service in breach of any law or of anyone else's rights.

We may remove any content, including share pages, and suspend or block access to the Service, at any time and for any reason, including if we believe you have broken these terms. If we suspend or block you, any further access to the Service is unauthorized. We don't have to monitor content, but we may.

Reporting content and copyright notices

If you believe a share page or other content on the Service is unlawful or infringes your rights, email legal@dupefont.com with the page address, a description of the problem and your contact details. We may remove the content, ask for more information or decline to act.

A copyright notice should identify the work you say is infringed and the page where it appears, state your interest or right in the work, include your name, address and signature (a typed name is enough for email), and include a statement that you believe in good faith that the use isn't authorized and that the information in your notice is accurate. If you are not the owner, say that you are authorized to act for the owner.

We handle copyright notices and counter-notices as the law that applies to us requires, including Canada's Copyright Act and, where it applies, the US Digital Millennium Copyright Act. We will, in appropriate circumstances, block access for people who repeatedly post infringing content.

Our rights

The Service, including its software, design, text, font descriptions and comparison notes, preview images, rankings, match data and the way they are compiled, belongs to Datacleave or its licensors and is protected by law. We give you a limited, personal, non-exclusive, non-transferable and revocable permission to use the Service as these terms allow. We may end this permission at any time. Any other use of our material needs our written permission. We expressly reserve all text and data mining rights in the Service, including under Article 4(3) of Directive (EU) 2019/790. Dupefont, Datacleave and our logos are our trademarks. You may not use them, or confusingly similar names, without our written permission.

The API and the ChatGPT app

You may use the API only within the limits we publish or apply, which we may change at any time, and only for purposes these terms allow. You may not resell, sublicense or wrap the API or its results, or offer them as part of another API or service. If you display results from the API, you must credit them as "Powered by Dupefont" with a link to dupefont.com. We may change, limit or withdraw the API at any time without notice. We may block addresses or uses that we think harm the Service or other users. When you use Dupefont inside ChatGPT, OpenAI's terms and policies also apply to your use of ChatGPT, and we are not responsible for ChatGPT or for what OpenAI does with your data.

Other websites and services

The Service links to, and relies on, services we don't control, such as Google Fonts, OpenAI and Microsoft Clarity. We are not responsible for their content, availability, terms or privacy practices. Your use of them is at your own risk and governed by their terms.

Disclaimer

The Service is provided "as is" and "as available". To the fullest extent permitted by law, Datacleave makes no promises or warranties of any kind, express or implied, about the Service, its results or any font, including warranties of accuracy, merchantability, fitness for a particular purpose, title and non-infringement. We don't promise that a font we suggest is free to use for your purpose, that its license information is correct, or that using it won't infringe someone else's rights.

Limitation of liability

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for any other liability that cannot be limited by law.

To the fullest extent permitted by law, Datacleave and its directors, officers, employees and contractors will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, business, goodwill or data, arising out of or related to the Service or these terms. This includes license fees, damages or costs you pay because you used a font, or relied on a result, found through the Service.

To the fullest extent permitted by law, our total liability for all claims arising out of or related to the Service or these terms is limited to the greater of CA$100 and the amount you paid us for the Service in the 12 months before the claim arose. These limits apply whatever the legal basis of the claim (contract, tort including negligence, statute or otherwise), even if we were told the loss was possible, and even if a remedy fails of its essential purpose.

Indemnity

To the fullest extent permitted by law, you will defend, indemnify and hold harmless Datacleave and its directors, officers, employees and contractors against any claim, loss, liability, damage, cost or expense, including reasonable legal fees, arising out of or related to your content, your use of the Service or of any font, your breach of these terms, or your breach of any law or anyone else's rights.

Ending your use

You can stop using the Service at any time. We may suspend or end your access at any time, with or without notice. The sections on your content (for material already shared or kept), our rights, disclaimer, limitation of liability, indemnity, governing law and the general terms continue after your use ends.

Changes to these terms

We may update these terms at any time by posting a new version on this page. The new version applies from its effective date. Where the law requires notice of a change, we will give it. If you keep using the Service after that, you accept it. If you don't accept it, stop using the Service.

Governing law and disputes

These terms, and any dispute arising out of or related to them or the Service, are governed by the laws of the Province of British Columbia and the federal laws of Canada that apply there, without regard to conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. If you are a consumer, this does not remove protections that the mandatory law of your country of residence gives you.

Before starting a claim, you must email us at legal@dupefont.com and give us 30 days to try to resolve it informally.

This paragraph does not apply to consumers in Québec. To the fullest extent permitted by law, claims must be brought individually and not as a plaintiff or class member in a class or representative proceeding, must be started within one year after they arose, and must be brought in the courts of British Columbia, which have exclusive jurisdiction. You and we submit to those courts.

General

These terms and the Privacy Policy are the whole agreement between you and us about the Service and replace any earlier agreement about it. If a court finds part of these terms unenforceable, that part will be enforced as far as possible and the rest stays in effect. If we don't enforce a right, we haven't given it up. You may not transfer these terms without our written consent; we may transfer them, for example as part of a merger, acquisition or sale of assets. We are not responsible for delays or failures caused by events outside our reasonable control. These terms don't give rights to anyone other than you, us and the people the liability and indemnity sections protect.
