Terms of service

Version of Sep 1, 2026, 12:00 AM

These terms govern the contract between you and PRALOJ LTD for the use of the vizvuz machine translation service at vizvuz.com and api.vizvuz.com. By creating an account you accept them.

1. Parties

The provider is PRALOJ LTD, 71-75 Shelton Street, Covent Garden, WC2H 9JQ London, United Kingdom, registered in the Companies House, England and Wales under company number 17216920 ("we", "us"). The customer is the natural or legal person who creates an account ("you").

Where you accept these terms on behalf of an organisation, you confirm that you are authorised to bind it.

2. Definitions

• Service — the translation API, the dashboard and the documentation.
• Character — one Unicode character of the text submitted to the API,

including spaces, line breaks, punctuation and any markup.

• Plan — the tariff selected in the dashboard, as published on the pricing page.
• Credit — prepaid balance that pays for usage under the pay-as-you-go plan.
• Included volume — the characters covered by the base fee of a subscription

plan in a billing period.

• Overage — usage above the included volume.
• Billing period — one month or one year, as chosen when subscribing.

3. Account, keys and team

You must give accurate registration details and keep them current. You are responsible for everything done with your API keys. Keys are shown once at creation and stored by us only as a hash; if a key is lost or exposed, revoke it in the dashboard immediately.

Billing, quota, rate limits and keys belong to a team, not to an individual user. The team owner is responsible for the acts of every member they invite.

You must be at least 18 years old and have legal capacity to contract.

4. The service

We provide machine translation between the language pairs published in the documentation, over an HTTP interface, together with a dashboard for keys, usage, glossaries and billing.

The service is provided as software as a service. No software is delivered to you and no copy of anything is transferred. We may change, add to or remove individual features. Where a change removes a feature you are actually using or materially reduces the service, we announce it at least 30 days in advance by e-mail, and you may terminate with effect from the date the change takes effect.

Machine translation is not a substitute for professional human translation. Output may contain errors. You are responsible for reviewing output before you rely on it in any context where an error would matter, including legal, medical, financial and safety-critical contexts.

5. Charges

5.1 Per character

Usage is charged per character of the text submitted, counted as defined in clause 2, including spaces, line breaks and markup. The context parameter is not charged. The number charged for a request is returned in the X-Characters-Billed header of the response and shown in the dashboard.

A translation served from our cache is charged in full, because you receive the same result.

Requests that fail — validation errors, rate limiting, engine failures — are not charged, and any reservation made for them is released immediately.

5.2 Pay as you go and credit validity

Under the pay-as-you-go plan you buy credit in advance. Credit is drawn down per character at the rate published on the pricing page for your currency.

Credit is valid for twelve months from the day it is topped up. We notify you by e-mail 30 days before any part of your balance expires. Expired credit lapses without refund. Credit has no cash value, is not transferable between accounts and is not exchangeable for money except where mandatory law requires a refund.

Every verified account receives 100,000 characters of free credit once. It is granted after e-mail confirmation, requires no payment method and is not transferable.

5.3 Subscriptions

Subscription plans are charged in advance for each billing period, monthly or yearly, at the price published for your currency at the time of subscribing. Each period includes the volume stated for the plan. Unused included volume does not carry over to the next period.

Upgrades take effect immediately, with the remainder of the current period charged pro rata. Downgrades take effect at the end of the current period.

5.4 Overage and the overage cap

Usage above the included volume is recorded per started 100,000 characters at the overage rate of your plan and charged at the end of the billing period as a separate payment.

Every subscription has an overage cap, which you can change in the dashboard and which you can set to unlimited. When the cap is reached the API stops translating and answers with HTTP 402 until the next period begins or you raise the cap. We warn you by e-mail at 80 % and at 100 % of the included volume.

The cap exists to protect you from a runaway integration. It is a control, not a guarantee: usage already recorded before the cap was reached remains payable.

5.5 Currency and prices

Prices are published per currency on the pricing page and are not converted live. You choose your billing currency with your first payment; it is fixed thereafter because invoices, credit and price lists are all denominated in it. Write to [email protected] if you need to change it.

We may change prices with at least 30 days' notice by e-mail. A price change takes effect for subscriptions at the start of the next billing period and for credit at the time of the next top-up; it never affects credit already bought. If you do not accept a price change you may terminate with effect from the date it takes effect.

6. Taxes

Prices are exclusive of value added tax and any other applicable turnover tax, which we add where we are required to.

Business customers in the European Union who supply a valid VAT identification number, validated against the European Commission's VIES service, are invoiced under the reverse charge mechanism and are responsible for accounting for the tax in their own country. Customers without a valid number are charged the rate of their country of residence. Customers outside the European Union are invoiced without European VAT; tax in the recipient country is your responsibility.

You must keep your country and tax details current. If incorrect details cause an incorrect tax treatment, you are responsible for the difference.

7. Payment and default

Payments are collected through our payment service provider using the method you select. Invoices are issued electronically and are available in the dashboard.

If a payment fails we retry and notify you. If an amount remains unpaid 14 days after it fell due, we may suspend the service until it is settled. If it remains unpaid 30 days after it fell due, we may terminate the contract. Statutory default interest applies.

Consumers may withdraw from a contract within 14 days under European law. Where you ask us to begin performance immediately — which is what happens when the API answers your first request — you owe a proportionate amount for the usage already delivered, and the right of withdrawal lapses once the service has been fully performed with your prior express consent.

8. Availability and service levels

We aim for continuous availability, and we publish measured availability and latency on our status page.

Availability is measured as the proportion of one-minute intervals in a calendar month in which the API answered non-error responses to valid requests. Excluded from the measurement are: scheduled maintenance announced at least 48 hours in advance; failures caused by your own systems, network or configuration; failures caused by circumstances beyond our reasonable control under clause 15; and suspension for non-payment or breach.

Where we miss the Business commitment in a calendar month, you may claim a service credit against the following month's base fee: 10 % where availability was below 99.9 % but at least 99.0 %; 25 % where it was below 99.0 % but at least 95.0 %; and 50 % where it was below 95.0 %. Claims must be made in writing to [email protected] within 30 days of the end of the month concerned. Service credits are the sole and exclusive remedy for missed availability, and total credits in any month cannot exceed that month's base fee.

9. Acceptable use

You must not use the service to:

• infringe any law of the United Kingdom, of the European Union or of the country

in which you or your users are located;

• process content you have no right to process, or transmit personal data without a

legal basis;

• generate or distribute unlawful content, including content that infringes

intellectual property, defames, harasses, or exploits children;

• attempt to circumvent quotas, rate limits, the character count or any technical

restriction;

• reverse engineer, resell or reconstruct the underlying models, or use the output

systematically to train a competing translation system;

• resell the service as your own translation API without a written reseller

agreement — building it into your own product is expressly permitted;

• probe, scan or load-test our infrastructure without written permission;
• share credentials with anyone outside your team.

Where we have reasonable grounds to believe this clause is being breached, we may suspend the affected key or account immediately and will tell you why. Where a suspension turns out to be unjustified, we credit the affected period.

10. Your data

You retain all rights in the text you send and the translations you receive. We claim no ownership of either, and we do not use your content to train models.

Where we process personal data on your behalf, our data processing agreement applies and forms part of this contract.

We store no submitted text in our usage records. Cached translations are held under a hash of the input and can be switched off per team at any time.

Each party must keep the other's confidential information confidential and use it only to perform this contract.

11. Our rights

The service, the website, the documentation and the software behind them remain our property. Nothing here transfers any right in them beyond the right to use the service during the term.

The code examples in our documentation are provided for you to copy, adapt and use in your own projects without restriction and without attribution.

You may state that you use vizvuz. Any other use of our name or marks needs our written consent.

12. Warranties

We provide the service with reasonable skill and care. Beyond that, and to the extent permitted by law, the service is provided as is. We do not warrant that translations are accurate, complete or fit for a particular purpose, nor that the service will be uninterrupted or error-free.

Nothing in these terms excludes or limits the statutory rights of a consumer.

13. Liability

We are liable without limit for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, and for any other liability that cannot lawfully be excluded or limited.

We are liable without limit for intent and gross negligence. For ordinary negligence we are liable only for breach of an obligation whose fulfilment is essential to the proper performance of the contract and on whose fulfilment you may reasonably rely, and in that case only for foreseeable damage typical of this kind of contract.

Subject to the paragraph above, our total liability arising in any twelve-month period is limited to the amount you paid us in the twelve months before the event giving rise to the claim, or the equivalent of one hundred euro in your billing currency, whichever is greater.

We are not liable for loss of profit, loss of business, loss of goodwill or indirect or consequential loss, nor for any damage resulting from your failure to review machine output before relying on it.

14. Term, termination and data after termination

The contract runs for the chosen billing period and renews automatically for the same period unless terminated.

You may terminate at any time in the dashboard, with effect from the end of the current billing period. Pay-as-you-go accounts may be closed at any time; unused credit is not refunded except where clause 5.2 or mandatory law requires it.

We may terminate for convenience with 30 days' notice, refunding the unused part of any prepaid base fee. Either party may terminate immediately for material breach that is not remedied within 14 days of written notice.

After termination your data remains available for 90 days so that you can export it, and is then deleted. Invoices and accounting records are retained for the periods required by tax law.

15. Circumstances beyond our control

Neither party is liable for failure to perform caused by circumstances beyond its reasonable control, including war, civil unrest, natural disaster, epidemic, industrial action, failure of public telecommunications networks, failure of a sub-processor caused by such circumstances, and acts of public authorities. The affected party must notify the other promptly. Where such circumstances persist for more than 30 days, either party may terminate.

16. Changes to these terms

We may change these terms with at least 30 days' notice by e-mail to the address on your account. If you do not accept a change, you may terminate with effect from the date it takes effect; continuing to use the service after that date counts as acceptance. Changes required by law take effect on the date the law requires.

17. Assignment

You may not assign this contract without our written consent, which we will not unreasonably withhold. We may assign it to a successor in connection with a merger, reorganisation or sale of the business, on notice to you.

18. Governing law and jurisdiction

This contract is governed by the law of England and Wales, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods.

The courts of England and Wales have exclusive jurisdiction over disputes arising out of it. Where you are a consumer, this choice does not deprive you of the protection of the mandatory provisions of the law of your country of habitual residence, and you may also bring proceedings in the courts of that country.

If any provision of these terms is held invalid, the remainder stays in force and the invalid provision is replaced by one that comes closest to its commercial purpose.
