These Terms of Service ("Terms") govern your use of qlot, the AI-powered document translation service operated by qtAI lab Co., Ltd. ("qtAI lab," "we," "us," or "our"), a company incorporated in the Republic of Korea.
By creating an account or using qlot, you agree to these Terms. Do not use the Service if you do not agree to them.
qlot is a software-as-a-service product that translates documents between languages while preserving their formatting and converts files between formats.
Translation supports Microsoft Word (.docx), Microsoft PowerPoint (.pptx), Microsoft Excel (.xlsx), Portable Document Format (.pdf), and Hangul Word Processor (.hwpx).
Conversion supports Portable Document Format (.pdf), Microsoft Word (.docx), Microsoft Excel (.xlsx), Microsoft PowerPoint (.pptx), OpenDocument Text (.odt), Rich Text Format (.rtf), plain text (.txt), Markdown (.md), HyperText Markup Language (.html), Comma-Separated Values (.csv), Joint Photographic Experts Group (.jpg), Portable Network Graphics (.png), WebP (.webp), Scalable Vector Graphics (.svg), SubRip subtitle (.srt), and Web Video Text Tracks (.vtt) as both source and destination formats. Electronic Publication (.epub), High Efficiency Image Coding (.heic), High Efficiency Image File Format (.heif), Hangul Word Processor (.hwpx), Apple Pages (.pages), Apple Numbers (.numbers), and Apple Keynote (.key) are supported as source formats only. Not every conversion combination of these formats is available.
The Service is provided through the qlot web application and, where available, through an API.
For these Terms:
New Accounts start on the Preview plan, which is provided without charge. On the Preview plan, qlot translates the whole of each document you upload but returns the result as a preview: the first 5 pages are shown as watermarked page images, and the only download is a watermarked PDF of those pages.
The Preview plan is subject to the following limits, which may change under Section 1.4:
You can obtain the full, unwatermarked results of your preview documents by purchasing the Intro Offer described in Section 5.7 or by subscribing to a Subscription Plan. Content submitted under the Preview plan may be used to improve our models as described in Section 4.2.
We may add, remove, or change features over time.
We will provide at least 30 days' notice by email or through the Service before making a material change that adversely affects paying users.
You must be at least 14 years old to create an Account. EU and EEA residents must be at least 16 years old.
When you create an Account on behalf of an organization, you confirm that you have authority to bind that organization to these Terms.
You are responsible for keeping your credentials secure and for activity that occurs through your Account.
Notify us promptly if you suspect unauthorized access. We use Keycloak for authentication and do not store passwords in plaintext.
An individual Account may be used by one natural person.
Team and Enterprise plans allow multiple users within the number of seats included in or purchased for the applicable plan.
You must not use qlot to:
"Unlimited" glossaries on the Team and Enterprise plans assume ordinary team translation work, subject to a fair-use ceiling of 1,000 glossaries per Account. It does not apply to translation volume: credit usage remains subject to the monthly allowance for your plan.
To protect the stability of the Service and the normal use of other customers, we may take reasonable measures, including:
Glossary storage is provided for managing translation terminology and may not be used as a general-purpose data store. Where use materially exceeds ordinary use, we may act under Section 3.3. If we introduce a new limit that adversely affects paying users, we will give notice in accordance with Section 1.4.
We may suspend or terminate an Account that violates these rules.
Where reasonable, we will notify you and provide an opportunity to correct the violation before termination. We may terminate an Account without a refund for severe or repeated violations.
You retain all rights to Customer Content.
You grant us only the limited rights needed to operate the Service. These rights allow us to receive, process, temporarily store, and return your files and the translation or conversion outputs produced from them.
We do not use Customer Content from paid Subscription Plans to train our AI models or third-party AI models.
Content submitted under a paid plan (Starter, Pro, Team, or Enterprise) is processed only to provide the requested translation or conversion and related Service functions.
Content submitted under the Preview plan may be used to improve and train our models. We apply technical measures to de-identify such content before use. To exclude your content from training, use any paid Subscription Plan.
Uploaded files and the translation or conversion outputs produced from them are automatically deleted within the retention period provided by your plan:
After the retention period, files are removed from primary storage. Backup copies are removed on a rolling basis.
AI translation is probabilistic and may contain errors.
We make reasonable efforts to provide accurate, high-quality translations, but we do not guarantee that an output will be complete, error-free, or suitable for a particular purpose.
You are responsible for reviewing translations before relying on them, especially in legal, medical, financial, regulatory, or safety-critical contexts.
File conversion rewrites a file into a different format, and formats differ in what they can express. Layout, fonts, and structural features may be approximated, simplified, or omitted where the destination format has no equivalent.
Where a conversion uses text recognition to read an image or a scanned page, the recovered text depends on the quality and legibility of the source.
We make reasonable efforts to produce accurate, high-quality conversions, but we do not guarantee that a converted file will be complete, error-free, visually identical to the source, or suitable for a particular purpose.
You are responsible for reviewing a converted file before relying on it, especially in legal, medical, financial, regulatory, or safety-critical contexts.
Available Subscription Plans, features, and prices are shown on the qlot pricing page .
The applicable price, currency, billing period, and included features are displayed before you confirm a purchase.
We may change prices by giving active subscribers at least 30 days' notice. A price change will apply from the next billing period after the notice period.
Each Subscription Plan includes usage limits — such as monthly credit and file allowances, maximum pages and size per file, simultaneous target languages, concurrent jobs, and OCR page limits — as disclosed on the pricing page. The same file-size and concurrency limits apply to translation and conversion. Material changes that adversely affect paying users are made in accordance with Section 1.4.
International purchases are processed by Paddle, our online reseller and Merchant of Record.
When you purchase a subscription through Paddle, Paddle is the seller of the transaction. Paddle processes the payment, calculates applicable taxes, issues the receipt or invoice, and appears on your payment statement.
The purchase is also subject to Paddle's Checkout Buyer Terms and related policies. These Terms continue to govern your use of qlot.
qtAI lab provides product and account support. Paddle handles payment processing and the financial execution of approved refunds.
Paid subscriptions renew automatically at the end of each billing period unless canceled.
Your payment method is charged at the beginning of each new billing period. The renewal price and billing schedule are shown at checkout and in your subscription settings.
Before a scheduled renewal charge, we send an advance reminder to the email address associated with your Account. The reminder states the amount and the date of the charge.
Annual subscriptions are charged once upfront for the 12-month term at the discounted price shown at checkout. Switching between monthly and annual billing takes effect at the next renewal date; no immediate charge or refund results from scheduling a switch.
You may cancel your subscription at any time through your Account settings without paying a cancellation fee.
Cancellation normally takes effect at the end of the current billing period. You may continue using the paid plan until that date, and you will not be charged for another period.
Canceling during an Intro Offer period prevents the renewal charge at the end of that period. Access to the Subscription Plan ends immediately on cancellation, and the Intro Offer payment is not refunded, as described in Section 5.7 and the Refund Policy.
Where a full refund is issued, the subscription ends immediately when the refund is processed. Access to paid features is withdrawn, and your registered payment method is deleted.
Unless stated otherwise, listed prices do not include VAT, GST, sales tax, or similar transaction taxes.
As Merchant of Record, Paddle calculates, collects, and remits applicable taxes based on the information provided at checkout. The final tax amount is displayed before payment.
Refunds are governed by our Refund Policy , which forms part of these Terms.
The Refund Policy explains:
Nothing in these Terms limits a statutory right that cannot legally be waived.
We do not offer free trials of Subscription Plans. A free trial that began under an earlier version of these Terms continues under that version until it ends.
Intro Offer. An Account on the Preview plan may purchase an Intro Offer once. The Intro Offer provides the first 30 days of the Subscription Plan that fits the preview documents being unlocked (Starter, Pro, or Team with 2 seats) at the intro price displayed at checkout, and unlocks the full results of those documents at the same time.
The intro price is determined by the preview documents you choose to unlock, and is displayed together with the plan, the renewal price, and the renewal date before you confirm the purchase. The Intro Offer cannot be applied to documents other than those unlocked at purchase.
Automatic renewal. Unless you cancel before the end of the 30-day period, the subscription renews automatically at the regular monthly price of that Subscription Plan displayed at checkout, and continues to renew under Section 5.3. You consent to this renewal separately at checkout.
You may withdraw your consent to renewal at any time before the renewal date by canceling the subscription from your Account settings (Settings → Subscription → Cancel subscription). Canceling stops the renewal and ends access to the plan immediately; it does not refund the intro price.
No withdrawal after unlocking. Because the Intro Offer unlocks your preview documents immediately at your request, you confirm at checkout that you request immediate performance and that you waive the right to withdraw from the Intro Offer purchase once the documents are unlocked. The intro payment is therefore not refundable except as required by applicable law or as described in the Refund Policy for billing errors and service defects.
Intro Offer eligibility is used when the offer is purchased. An Account that has used its Intro Offer cannot purchase another, including after cancellation, expiry, or a refund.
We may also offer promotional pricing from time to time, on the terms presented at the time of the offer.
Team plans include a monthly usage allowance (the “usage pool”), calculated as the number of seats multiplied by 20,000 credits.
Team members are included in the Team subscription held by the team leader.
They do not hold their own subscription while they remain members of that team.
Only where you have given prior, express consent, usage beyond the pool (“overage”) may incur charges at the unit price and billing cadence disclosed on the pricing page and at the time of consent.
That consent remains in effect for the duration of the applicable subscription and may be withdrawn at any time by contacting support.
On withdrawal, further overage charges stop and use beyond the usage pool is blocked.
Withdrawal does not create a charge for usage that occurred before it, and no overage is billed retroactively as a result of the withdrawal.
Without consent, use of the Service may be limited once the usage pool is exhausted, and no overage charges will be made.
If a payment for overage fails, further use beyond the usage pool is blocked until the outstanding amount is settled, so that unpaid overage does not continue to accumulate.
Refunds for overage charges are governed by Section 5.4 of the Refund Policy.
Enterprise plans are governed by a separate written agreement.
When an Enterprise agreement conflicts with this Section 5, the Enterprise agreement controls with respect to pricing, invoicing, billing, and refunds.
API access is provided under Enterprise agreements and is subject to the limits stated in the applicable agreement.
Credit and file allowances refill on each scheduled renewal date, and unused credits do not roll over to the next period.
Allowances refill only on a scheduled renewal.
Canceling a subscription, receiving a refund, or subscribing again does not refill an allowance or reset recorded usage for the period in progress.
Usage recorded during a period continues to count against your allowance for that period, including after a downgrade to the Preview plan.
Each file deducts a minimum of 10 credits.
The credit amount displayed when you upload a file is the billing basis for that translation; no additional credits are deducted after the translation begins.
A file conversion draws 10 credits from the same monthly allowance. Conversions are not counted against the files-per-month figure for your plan.
Credits have no cash value, are not redeemable for money, and expire when the subscription ends, subject to the Refund Policy.
Credit deduction rates by language direction are disclosed in the Service and may be adjusted from time to time. Adjustments apply prospectively to files uploaded after the change; material adjustments that adversely affect paying users are made in accordance with Section 1.4. The credit amount quoted at upload always remains the billing basis.
The Service, including its software, source code, models, trademarks, interfaces, and design, is owned by qtAI lab or its licensors.
We grant you a limited, non-exclusive, non-transferable, and revocable right to use the Service for its intended purpose while these Terms remain in effect.
You may send us feedback or suggestions.
We may use that feedback without payment or other obligation to you. We will not identify you as the source without your consent.
We aim to keep the Service available and reliable.
We do not guarantee uninterrupted availability unless a written Enterprise service-level agreement states otherwise. The Service may be unavailable during maintenance or because of circumstances outside our reasonable control.
Except where these Terms expressly state otherwise or applicable law requires otherwise, the Service is provided "as is" and "as available."
We disclaim all warranties, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.
To the fullest extent permitted by law, qtAI lab will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages.
This includes loss of profits, revenue, goodwill, business opportunities, or data, even when we have been advised that such loss may occur.
Our total aggregate liability arising from or relating to the Service or these Terms will not exceed the greater of:
Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited, including liability for gross negligence, willful misconduct, or death or personal injury caused by negligence.
To the extent permitted by law, you agree to defend, indemnify, and hold harmless qtAI lab, its affiliates, officers, employees, and representatives from third-party claims, damages, losses, and reasonable legal expenses arising from:
You may delete your Account at any time.
Deleting your Account ends these Terms as they apply to you, except for provisions that are intended to survive termination, including Sections 6, 8, 9, and 11.
We may suspend or terminate access to the Service when:
Where practicable, we will notify you and provide an opportunity to correct the issue.
After termination, Customer Content is deleted according to the applicable retention period.
You may request an export of available Account data within 30 days after termination by contacting support.
These Terms are governed by the laws of the Republic of Korea, without regard to conflict-of-law principles.
The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Disputes are subject to the exclusive jurisdiction of the Seoul Central District Court in the Republic of Korea.
For consumers, this provision does not remove mandatory protections available under the laws of your country of residence. Where those laws require otherwise, you may bring a claim in the courts of your place of residence.
Before starting formal proceedings, contact us at hello@qlot.ai .
Many concerns can be resolved through direct communication.
We may update these Terms.
We will provide at least 7 days' notice before a material change takes effect and at least 30 days' notice when a change is materially unfavorable to users.
Continued use after the effective date means that you accept the updated Terms. Where applicable law requires affirmative consent, we will request it separately.
You may not assign these Terms without our prior written consent.
We may assign these Terms as part of a merger, acquisition, corporate reorganization, or sale of assets.
If a provision of these Terms is found unenforceable, the remaining provisions will continue in effect.
These Terms, together with our Privacy Policy , Refund Policy , and any Enterprise agreement between you and qtAI lab, form the entire agreement governing the Service.
This English version governs the international Service and purchases processed through Paddle.
The Korean-language Service is governed by separate Korean terms.
Translations of this English version may be provided for convenience. Unless mandatory law requires otherwise, the English version controls for the international Service.
