Jianyi Terms of Service

Welcome to Jianyi's PDF document translation service. Please read and understand these Terms carefully before using the service. By registering, signing in, or using the service in any way, you agree to be bound by all of these Terms.

1. Service Description

What we provide: Jianyi offers pay-per-use PDF document translation. After you upload a PDF, the system parses it and generates a quote; once you confirm the quote and pay with credits, the document enters the translation queue, and you can download the translated PDF with its original layout preserved.
Supported files: PDF only, up to 50MB and 300 pages per file; both text-based and scanned PDFs are supported (scanned pages are translated after OCR recognition; quality depends on the original's clarity).
Languages: Multiple mainstream target languages are supported, as shown on the service pages, and more are being added.

2. Account and Registration

Account identifier: You register with an email address. Registration requires human verification; disposable email addresses are not supported.
Email verification: After registering, you must verify your email before signing in and using the service.
Account security: Keep your password safe. Losses caused by voluntarily disclosing your password or by attacks on your account are your responsibility. When abnormal sign-in activity is detected, the system temporarily locks the account and sends an email notice.
Account lockout: After consecutive failed sign-in attempts reach the threshold, the account is temporarily locked (starting at 15 minutes, doubling each time, capped at 24 hours); signing in is disabled during the lockout.

3. Credits and Billing

3.1 Credit unit

1 credit = ¥0.01. Recharges over one yuan include bonus credits — the more you recharge, the more you get. Credits are non-cashable, non-transferable, and cannot be gifted.

3.2 Billing rules

Quote basis: Billing is based on all text characters in the document that will be translated (excluding whitespace); scanned pages are billed per page. You can verify character counts with Word's "Word Count → Characters (no spaces)".
Unit prices:
- Text translation: ¥0.15 per 1,000 characters (15 credits per 1,000 characters);
- Scanned page OCR + translation: ¥0.5 per page (50 credits per page);
- Each translation task charges a minimum of 1 credit (no other minimum spend).
Quote validity: A quote is valid and price-locked for 24 hours from generation. After expiry, re-upload the file; re-quoting is free and instant.
Cache discount: Re-translating identical content qualifies for a discount, as shown by the credits payable at quote confirmation.

3.3 Credit validity

Paid credits: purchased with money, never expire;
Gift credits: valid for 7×24 hours (168 hours) from the time they are granted; unused portions automatically expire;
Consumption order: gift credits are consumed first, then paid credits.

3.4 Refund rules

Refundable cases: For failed translations, timed-out translations (no progress for 60 minutes or beyond the execution cap), and tasks cancelled while queued, credits are automatically refunded in full.
Refund method: The paid portion returns to your paid bucket (never expires); if the original gift batch has expired, the gift portion is returned as new gift credits with a fresh 7×24-hour validity from the refund time.
Non-refundable cases: Translation tasks that have been downloaded, and cache-hit services already consumed.

3.5 Recharge

Recharges are processed by a third-party payment channel, with payments handled independently by the third party; credits arrive automatically once payment succeeds.
If credits do not arrive immediately after payment, the system reconciles automatically within about 5 minutes — no need to contact support.
Recharge orders unpaid for 30 minutes are closed automatically with no charge.
Purchased credits are non-withdrawable and non-transferable (see 3.1).

4. Acceptable Use

Lawful use: You promise not to use the service for any illegal activities and not to upload documents containing:
- Content that violates the fundamental principles of the Constitution;
- Content that endangers national security, divulges state secrets, subverts state power, or undermines national unity;
- Content that harms national honor or interests;
- Content that incites ethnic hatred or discrimination or undermines ethnic unity;
- Content that infringes others' intellectual property, trade secrets, privacy, or other lawful rights;
- Content that is obscene, pornographic, related to gambling, violent, terrorist, or incites crime;
- Other content prohibited by laws and regulations.
Prohibited behavior: Do not abuse signup gift credits or evade billing through automated scripts, multiple accounts, or similar means. When abuse is detected, the platform may suspend or terminate the service and claw back related credits.
Concurrency limit: Each account may have only one translation task running at a time.

5. File Management

Retention periods:
- Files uploaded but never submitted for translation: kept for 24 hours, then auto-deleted;
- Task files submitted for translation: kept for 30 days, then auto-deleted;
- Translation outputs (translated PDFs): downloadable repeatedly for 30 days; afterwards, identical content can be regenerated at a discounted rate.
Storage quota: Each user's online file storage quota is 1GB (including unused and task files).
File deletion: You may delete unused files at any time; deleting a file also voids its valid quotes.

6. Task Cancellation

Cancellable while queued: While a task is queued, you may cancel it at any time for a full credit refund.
Not cancellable while translating: Once translation starts, the task cannot be cancelled. This rule is part of these Terms; by clicking Confirm on the quote page you acknowledge and accept it.
System termination: If a translation fails or times out, the system terminates the task automatically and refunds in full — no application needed.

7. Intellectual Property

Your documents: The intellectual property of documents you upload belongs to you or the original rights holder. By uploading, you warrant that you have the lawful right to use the document.
Translation outputs: The right to use translation outputs belongs to you. Intermediate data generated while providing the service (such as document fingerprints and paragraph-level translation caches) belongs to the platform.
The service itself: The software, technology, and interface design of this service are the intellectual property of the Jianyi operator.

8. Disclaimers

Translation quality: Machine translation may be inaccurate, especially for technical terminology, complex sentences, and low-quality scans. Please proofread important documents yourself. Translation quality for scanned documents depends on the original's clarity.
Service interruption: For interruptions caused by force majeure, system maintenance, or third-party failures, the platform will restore service as soon as possible but is not liable for indirect losses.
Data security: The platform takes industry-standard measures to protect your data but cannot guarantee absolute security. Losses caused by your own actions (such as disclosing your password) are your responsibility.

9. Changes to These Terms

The platform may modify these Terms from time to time as needed. Modified Terms will be published on the website.
If you continue using the service after a modification, you are deemed to accept the modified Terms.
If you do not accept the modified Terms, please stop using the service.

10. Dispute Resolution

These Terms are governed by the laws of the People's Republic of China.
Any dispute arising from or relating to these Terms shall first be resolved through friendly negotiation. If negotiation fails, either party may bring a lawsuit before the people's court with jurisdiction at the location of the Jianyi operator.
