Terms of Service

Please read these terms carefully before using LINGUAE

Effective October 11, 2026

The French version prevails if the two versions differ (see section 17). Lire la version française.

1. Who we are and what this contract covers

Linguae is a desktop application that translates documents offline. It is published by Linguae Technologies Inc. ("Linguae", "we", "us"), Montreal, Quebec, Canada. Email: yanis.aksas@gmail.com.

These terms (the "Terms"), together with the Privacy Policy, are the contract between you and us for your use of the Linguae application, the linguae.app website and the online services that come with them (together, the "Service").

If you buy the Enterprise plan, the quote, order form or Enterprise agreement signed with us (the "Enterprise Agreement") prevails over these Terms if they conflict.

2. Acceptance

You accept these Terms and the Privacy Policy the first time you open the application, before you can use it, or when you buy a subscription or credits. If you do not agree, do not use Linguae.

You must be of the age of majority where you live (18 in Quebec) to buy a paid plan. If you use Linguae on behalf of an organization, you state that you have the authority to bind it.

3. The Service

Linguae translates documents on your computer, using machine translation models that run locally:

  • supported formats: PDF, DOCX, PPTX, XLSX, TXT and Markdown;
  • two engines: Standard (one language pair per model) and Premium (multilingual models, for paid plans);
  • bundled domain glossaries, a local translation memory (paid plans), quality comparison and Deep Review (Pro plan, runs locally and for now only on Apple Silicon Macs).

Normal translation does not send your document to our servers. Some features need the internet: license activation and renewal, purchases, downloading models and their components, application updates, the Enterprise portal and, if you turn them on, the usage statistics and start ping described in the Privacy Policy.

4. Plans

The features and limits below are those of the application on the effective date. We may change them under section 18.

4.1 Free

  • 10 documents per month, counted on your device;
  • files up to 5 MB and up to 100 pages per document;
  • Standard engine and bundled domain glossaries;
  • optional pay-per-document credits (section 5);
  • community support, and email support with no committed response time.

4.2 Pro

  • monthly or annual subscription, at the prices shown before you pay (on the effective date: US$9.99 per month or US$99.99 per year);
  • unlimited documents and pages, subject to reasonable use and the technical limits of your device;
  • files up to 50 MB;
  • Standard and Premium engines, translation memory, quality comparison, Deep Review;
  • email support.

4.3 Enterprise

  • custom quote pricing;
  • files up to 200 MB unless otherwise agreed;
  • Pro features, plus the Enterprise organization, the organization admin portal and seat management;
  • API access, priority support, service levels or custom models only if they are in the Enterprise Agreement;
  • unless the Enterprise Agreement says otherwise, if the organization's subscription ends or is not paid, seats stay active for 7 days and are then revoked.

5. Pay-per-document credits

A credit bundle is a one-time purchase that lets you translate more documents than the monthly Free quota. One credit covers one document, within the Free plan's size limits. A bundle does not unlock Pro or Enterprise features.

On the effective date the bundles are: 5 documents for US$2, 20 documents for US$7 and 50 documents for US$15.

  • Credits are valid for 12 months from purchase. They remain available if you move to a paid plan and can be used again if you return to the Free plan during that period. Credits not used by the expiry date are deleted.
  • A credit is reserved when a translation that uses it starts. It is returned to you if that translation fails or is cancelled.
  • Credits are tied to the device used for the purchase, to prevent fraud and sharing. They are not transferable or redeemable for money, except for refunds under section 7.

6. License, devices and offline use

We grant you a personal, non-exclusive, non-transferable and revocable license to use the software for your lawful needs. The software is licensed, not sold. It remains our property (or our licensors'): the code, design and brand are not distributed under an open-source license.

  • Devices. A paid license can be activated on up to 3 devices. You can remove one from the application (Settings, Registered devices) or from the activation screen with your key and email. The number of replacements is limited over a 30-day period (6 on the effective date) to prevent sharing.
  • License key. It is confidential. You must not share, sell, lend or sublicense it.
  • Offline. After activation, the application works offline with a license token valid for about 30 days, which it renews by itself when online. A device that stays offline well beyond that period must reconnect to renew the token before using paid features again. The Free plan is not affected.

7. Prices, payment, renewal, cancellation and refunds

7.1 Prices and taxes

Prices are in US dollars (USD). The total to pay is shown before you confirm a purchase. Applicable sales taxes (such as GST, QST or VAT) are, where we must collect them, added and shown before you pay. On the effective date, no tax is added to the displayed price.

7.2 Payment

Payments are processed by Stripe. We do not receive your full card number. Enterprise purchases may also be made by payment link, invoice or the Enterprise Agreement.

7.3 Automatic renewal

A Pro subscription renews automatically at the end of each period (monthly or annual), at the then-current price shown at that time, until you cancel. If a renewal payment fails, we tell you and paid features may be suspended until it is settled.

7.4 Cancelling

You can cancel at any time, with no cancellation fee, in the application (Settings, Subscription, Manage) or from the link in the receipt Stripe sends you. Except for the refunds below, cancellation takes effect at the end of the period already paid and you keep access until then. Licenses obtained without going through Stripe are managed by writing to us.

7.5 7-day refund guarantee (Pro)

If Pro is not right for you, write to us within 7 days of buying or renewing a Pro subscription and we will refund the full price you paid, no questions asked. The related license is then revoked.

A credit bundle with no credits used is refunded in the same way. If some credits have been used, the refund covers the remaining credits, unless the law requires more. The Enterprise plan is refunded under the Enterprise Agreement.

We refund to the original payment method within 15 days of your request.

7.6 Consumers in the European Union, the European Economic Area and the United Kingdom

If you are a consumer in these territories, you may withdraw from a purchase within 14 days of buying it, without giving a reason, by writing to us (for example: "I withdraw from my purchase of [date]"). We refund the full price paid within 14 days of your request. For you, this 14-day period replaces the 7-day period of section 7.5: the 7-day guarantee never reduces this right.

7.7 Technical problems

If a verified problem prevents us from providing the Service you paid for and we cannot fix it within a reasonable time, we refund the unused part of the paid period.

7.8 Other rights

Sections 7.5 to 7.7 are in addition to the rights the law gives you, including, for consumers in Quebec, those under the Consumer Protection Act. They do not replace them.

8. Your obligations

You agree to:

  • use Linguae lawfully, including with respect to privacy, intellectual property and the rules of your profession;
  • translate only content you have the right to process;
  • not circumvent license, quota, device or credit limits, or security measures;
  • not decompile, disassemble or modify the software, except to the extent the law allows despite this restriction;
  • not use the Service to produce or distribute unlawful, malicious or infringing content, or to harm our systems;
  • comply with the export and sanctions laws that apply to you.

9. Your documents and translations

Your documents, translation memory and translations belong to you. They stay on your device. We do not receive them, read them or use them, whether to train models or for anything else. You grant us only the rights needed for the software to process them on your device.

You are responsible for backing them up, for their content and for your right to translate them.

10. Translation quality

Linguae uses artificial intelligence. Translations, like quality analyses and Deep Review, may contain errors, omissions, formatting problems, terminology mistakes or mistranslations. You must review them before relying on them, especially for legal, medical, financial, tax, immigration, court or safety-related documents. Linguae is not a substitute for a translator, lawyer, doctor, accountant or other professional.

11. Intellectual property and third-party components

The software, its design and its brand belong to Linguae Technologies Inc. or its licensors. Rights not expressly granted are reserved.

Linguae includes open-source components and translation models published by third parties under their own licenses. Their notices and licenses are at https://linguae.app/credits. Those licenses apply to those components, not to the rest of the software.

If you send us suggestions, we may use them freely, with no obligation to you.

12. Privacy

How we process your personal information is described in the Privacy Policy, which is part of the contract.

13. Availability, third-party services and support

We may change, improve, suspend or withdraw parts of the Service. Some features depend on things we do not control: the internet, the availability of models and components downloaded from third parties (Hugging Face, GitHub, python.org and PyPI), payment and hosting providers, and the compatibility of your system.

Support is by email, with no guaranteed response time, unless your Enterprise Agreement provides one. If we end a part of the Service you have paid for, we refund the unused part of the paid period.

14. Suspension and end of the contract

We may suspend or end your access, after notifying you when possible, if you seriously breach these Terms, do not pay, circumvent technical restrictions, endanger our security or if the law requires it. In that case we refund the unused part of the paid period, unless you breached the Terms fraudulently.

When the contract ends, the paid license is revoked and you can keep using the Free plan. Provisions that by their nature should survive (intellectual property, liability, governing law) continue to apply.

15. Warranties and liability

15.1 If you are a consumer

Nothing in these Terms deprives you of the rights and warranties the law gives you and that cannot be waived, including the legal warranty of quality and, in Quebec, the rights under the Consumer Protection Act and the Civil Code of Québec. Our liability is never excluded or limited for intentional or gross fault, for bodily or moral injury, or for anything the law does not allow us to limit.

15.2 If you use Linguae for your business or profession

To the extent permitted by law:

  • Linguae is provided "as is" and "as available". We do not warrant that translations will be accurate, complete or suitable for your purpose, that formatting will always be preserved, that the Service will be uninterrupted or error-free, or that every file will be supported;
  • we are not liable for indirect or consequential damages, lost profits, data or goodwill, or the consequences of relying on a translation;
  • our total liability is limited to the amounts you paid us for the Service in the 12 months before the event, or CAD $100 if you paid nothing;
  • you indemnify us against third-party claims arising from your content, your unlawful use of the Service or your breach of these Terms.

16. Governing law and disputes

These Terms are governed by the laws of Quebec and the federal laws of Canada that apply there. Unless the law requires another court, the courts of the judicial district of Montreal have jurisdiction.

If you are a consumer, you keep the right to rely on the mandatory provisions of the law of your place of residence and to go to the courts that have jurisdiction there, including those of Quebec if you live there. We do not impose arbitration or a waiver of class actions.

17. Language

The parties have expressly required that these Terms and related documents be drawn up in French. The English version is a convenience translation: if the two differ, the French version prevails.

18. Changes

We may change these Terms and the plans.

  • For an important change that affects a current subscription or bundle (including a price increase, a reduction of paid features or a new obligation), we send you written notice, by email to your account address, at least 30 days before it takes effect. The notice states the change, the previous clause and the effective date. You may refuse the change and cancel without charge before that date, with a refund of the unused part of the paid period.
  • For any other change, we publish the updated version with its new date and show it to you in the application, where we ask you to accept it again before continuing.

Purchases already made remain governed by the price and features that applied when you bought, until the end of the paid period.

19. General

If a provision is invalid, the others continue to apply. Not exercising a right is not a waiver. We may assign the contract as part of a sale of our business, without reducing your rights. We are not liable for a failure caused by force majeure. We write to you at your account address; you write to us at the address below.
