Legal
These Terms of Service (the “Terms”) form a binding agreement between you and Lars Gisler, [STREET_ADDRESS], [POSTAL_CODE] [CITY], Switzerland (“dojo”, “we”, “us”, or “our”), governing your access to and use of the dojo website, applications, and related services (collectively, the “Service”).
By creating an account, accessing, or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy. If you do not agree to these Terms, you must not access or use the Service.
If you use the Service on behalf of an organisation, you represent that you have authority to bind that organisation, and “you” refers to that organisation.
dojo is a writing-practice tool for language learners. It uses automated, artificial-intelligence systems to grade text you submit, generate corrections, scores, feedback, and study summaries, and present that feedback through tutor personas. The Service is provided for personal, educational, self-study purposes only.
The Service is a practice aid. It is not a substitute for a qualified teacher, a professional translator, an interpreter, a proofreader, or any certified language assessment, and it must not be relied upon as such.
All grades, scores, corrections, explanations, translations, examples, and other feedback produced by the Service are generated automatically by artificial-intelligence language models. They are produced by machines, not by qualified human teachers or linguists, and they may be incomplete, inaccurate, outdated, misleading, or simply wrong.
AI language models can “hallucinate” — that is, produce confident-sounding output that is factually or grammatically incorrect. A correction may introduce an error, miss a real mistake, mark correct language as wrong, apply the wrong register or dialect, or give an explanation that does not reflect accepted usage. Scores are indicative only and have no official, certified, or standardised meaning.
The feedback does not constitute professional, educational, translation, certification, legal, or other expert advice. You must independently verify any output before relying on it, especially for academic, professional, official, commercial, or any other consequential use. You use AI-generated feedback entirely at your own risk, and you are solely responsible for any decision you make or action you take based on it.
Tutor personas are stylistic presentations only. The tone, personality, and “character” of a persona — including blunt, informal, or in-character remarks — do not change the fact that the underlying feedback is machine-generated and may be wrong, and do not represent the views of dojo.
You must be at least 16 years old, or the age of digital consent in your country, to use the Service. By using the Service you represent that you meet this requirement and that the information you provide is accurate.
You sign in through Google. You are responsible for maintaining the security of the account you use to access the Service and for all activity that occurs under your account. You must notify us promptly at info@write-dojo.com of any unauthorised use or suspected security breach. You may not share your account, or let anyone else use it, and you may not create an account by automated means.
AI grading is performed using Google’s Gemini API. When you submit text for grading, that text is sent to Google’s Gemini API. Your use of Google’s services is governed by Google’s own terms, and any data handling on Google’s side is subject to those terms.
Payments are processed by Paddle.com Market Ltd (“Paddle”), which acts as the merchant of record and reseller of the Service for all paid plans. Your purchase is therefore also subject to Paddle’s own terms and privacy notice, and Paddle — not we — is responsible for collecting payment and for charging and remitting any applicable VAT or sales tax. See Section 9.
We are not responsible or liable for any act, omission, outage, billing, content moderation, change, or discontinuation by Google or any other third-party provider, or for any loss arising from your use of such third-party services.
You agree that you will not, and will not attempt to:
We may, but are not obliged to, monitor use of the Service to enforce these Terms and to protect the Service, our users, and the public.
You retain ownership of the text and other content you submit to the Service (“Your Content”). You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process, transmit, and display Your Content solely to operate, secure, and provide the Service to you — including transmitting it to the third-party AI provider for grading as described in these Terms and in the Privacy Policy.
You are solely responsible for Your Content and you represent that you have all rights necessary to submit it and to grant the above licence. We do not claim ownership of Your Content and do not use it to train our own models. AI-generated feedback returned to you is provided for your personal study use; given its nature (see Section 3) we make no representation that it is original, accurate, or free of third-party rights.
The Service, including its software, design, text, graphics, logos, tutor personas, and the “dojo” name and branding, is owned by us or our licensors and is protected by intellectual property laws. Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the Service for its intended purpose. No other rights are granted.
Access to the Service requires a paid subscription (“Dojo Pro”), except during a free trial where one is offered. The price, billing period, and any discount or trial that applies to you are shown before you confirm your purchase, and those details form part of these Terms.
Fair use. A subscription is for your own personal study use and is subject to reasonable technical usage limits — including limits on how many AI requests you may make in a given period and on the length of individual submissions — which we apply to keep the Service available, secure, and affordable for everyone. These limits are set at a level intended not to affect ordinary personal use; where you reach one, the app tells you and when it resets. We may adjust these limits where necessary for operational, security, or cost reasons, and we may throttle, suspend, or terminate use that is automated, shared between several people, or otherwise excessive or abusive.
Free trial. Where we offer a free trial, you start it by completing checkout and providing a payment method. Unless you cancel before the trial ends, the subscription converts automatically into a paid subscription at the price shown at checkout, and your payment method is charged. A trial is limited to one per person and per account; we may withdraw or change trial offers at any time for future sign-ups.
Billing and renewal. Subscriptions are billed in advance for each billing period and renew automatically for further periods of the same length until cancelled. Prices are stated in euros and are exclusive or inclusive of VAT or other applicable taxes as indicated at checkout; Paddle, as merchant of record, determines, charges, and remits those taxes. Any founding or promotional discount applies only for as long as we state at checkout and only while your subscription remains continuously active.
Cancellation. You may cancel at any time from the billing settings in your account. Cancellation takes effect at the end of the current billing period: you keep access until then, and no further amounts are charged. Cancelling does not by itself delete your account or your data — see Section 14 and the Privacy Policy.
Failed payments. If a payment is not collected, we may suspend or restrict access to paid features while payment remains outstanding, and the subscription may be cancelled if collection continues to fail.
Refunds and right of withdrawal. Payments are otherwise non-refundable except where refunds are required by mandatory law. If you are a consumer in the EU, the EEA, the UK, or Switzerland, you may have a statutory right to withdraw from the contract within fourteen days. By starting to use the Service immediately after purchase you expressly request that we begin performance during that period and acknowledge that you lose the right of withdrawal once the Service has been fully performed; where performance has begun but is not complete, you may be required to pay for the portion already provided. Refund requests are handled by Paddle as merchant of record, and you can also contact us at the address in Section 18.
Price changes. We may change subscription prices or introduce new plans. We will give you reasonable advance notice of any price change affecting your subscription, and the new price will apply from the next billing period after the notice. If you do not accept the change, you may cancel before it takes effect.
The Service is provided on an “as available” basis. We do not guarantee that the Service will be uninterrupted, timely, secure, or error-free, and we may modify, suspend, limit, or discontinue all or part of the Service, including any feature, persona, or model, at any time and without liability to you. We will use reasonable efforts to give notice of material adverse changes where practicable.
To the fullest extent permitted by applicable law, the Service and all of its output are provided “as is” and “as available”, without warranties or guarantees of any kind, whether express, implied, or statutory.
Without limiting the foregoing, we expressly disclaim all implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, and any warranties arising from a course of dealing or usage of trade. We do not warrant that the Service will meet your requirements, that it will be available, uninterrupted, secure, or error-free, that any defect will be corrected, or — as set out in Section 3 — that any AI-generated grade, correction, translation, or other output will be accurate, complete, reliable, current, or suitable for any purpose.
No advice or information, whether oral or written, obtained from us or through the Service, creates any warranty not expressly stated in these Terms.
To the fullest extent permitted by applicable law, dojo and its owners, directors, employees, and suppliers shall not be liable for any indirect, incidental, special, consequential, punitive, or exemplary damages, or for any loss of profits, revenue, data, goodwill, study progress, or other intangible losses, arising out of or in connection with these Terms or your use of (or inability to use) the Service.
This includes, without limitation, any loss or damage arising from your reliance on AI-generated grades, corrections, translations, or other output, from any inaccuracy or error in that output, from any interruption or unavailability of the Service, from any act or omission of a third-party provider such as Google.
To the fullest extent permitted by applicable law, our total aggregate liability for all claims relating to the Service shall not exceed the greater of (a) the total amounts you paid us, if any, for the Service in the twelve (12) months before the event giving rise to the claim, or (b) [CHF 100].
Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under Swiss law — in particular liability for unlawful intent or gross negligence, for death or personal injury caused by our negligence, or any mandatory liability owed to consumers. Where liability cannot lawfully be excluded, it is limited to the minimum extent permitted by law.
To the extent permitted by applicable law, you agree to indemnify and hold harmless dojo and its owners, directors, employees, and suppliers from and against any claims, liabilities, damages, losses, and reasonable expenses (including legal fees) arising out of or related to Your Content, your use of the Service, your violation of these Terms, or your violation of any law or third-party right.
You may stop using the Service at any time and may delete your account, and with it your data, from Settings. If you have a subscription, cancel it first: deleting the account does not cancel your subscription, and account deletion is blocked while a subscription can still bill.
We may suspend or terminate your access to the Service, in whole or in part, at any time and with immediate effect — including by disabling or deleting your account — if we reasonably believe that you have violated these Terms, that your use poses a security, legal, or operational risk, or that suspension or termination is required to comply with the law. Where reasonable and lawful, we will give you notice.
We may also discontinue the Service generally with reasonable notice. On termination for any reason, your right to use the Service ends immediately, and no refund is due for the remainder of a billing period except where we terminate without cause or where a refund is required by mandatory law. Sections that by their nature should survive — including Sections 3, 7, 8, 9, and 11 to 16 — survive termination. Deletion of your data on account closure is handled as described in our Privacy Policy.
We may update these Terms from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, notify you. Changes take effect when posted unless stated otherwise. Your continued use of the Service after a change means you accept the revised Terms; if you do not agree, you must stop using the Service and may delete your account.
These Terms and any dispute or claim arising out of or in connection with them or the Service (including non-contractual disputes) are governed by the substantive laws of Switzerland, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods (CISG).
The exclusive place of jurisdiction for any dispute is the competent courts of Solothurn, Switzerland. This does not deprive a consumer of the protection of any mandatory provisions, or of any mandatory place of jurisdiction, available to them under the law of their country of residence.
If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force, and the invalid provision will be replaced by a valid one that comes closest to its intended purpose. Our failure to enforce any right or provision is not a waiver of it. You may not assign or transfer these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets. These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the Service and supersede any prior agreement on that subject.
Questions about these Terms can be sent to info@write-dojo.com, or by post to Lars Gisler, [STREET_ADDRESS], [POSTAL_CODE] [CITY], Switzerland. See also our Imprint.
