TERMS
Terms of Service, free to use, please do not abuse.
By accessing or using Tushuo Lab you agree to the terms below. They are deliberately short, clear and enforceable.
The service
This site offers free online tools and playful content. Most features run locally in your browser with no registration. We may add, change or retire any feature or page at any time.
Your licence to use the site
- You may use the site free of charge for personal, work and commercial purposes.
- Do not scrape, load-test or attack the site, and do not interfere with other users.
- Do not use the tools for illegal purposes or publish misleading information in our name.
- Sharing links to our pages is always welcome; bulk-copying content to build a competing site requires permission first.
Your content
Text and files you enter or upload remain yours. Because processing happens locally, we neither receive nor store your content, and we are not responsible for backing it up — please keep your own originals.
Disclaimer
- All tools are provided "as is". We work hard on accuracy but cannot guarantee that every result is error-free.
- Verify calculations yourself: amounts, taxes, loans, BMI, BMR and due dates are for reference only and do not constitute financial, medical or legal advice.
- We are not liable for any direct or indirect loss arising from use of, or inability to use, this site.
- Content behind third-party links is the responsibility of its own operator.
Intellectual property
The site name, page copy, original code and visual design belong to us. Third-party open-source libraries (such as pdf-lib, ffmpeg.wasm, tesseract.js and three.js) remain under their respective licences.
Changes and termination
We may pause the service for maintenance, upgrades or reasons beyond our control, and may retire the site entirely; whenever possible we will announce this in advance on the site.
Prohibited behaviour
- Bypassing rate limits or protections to send bulk requests, i.e. using the site as a free automation endpoint.
- Publishing content in our name, or repackaging the tools as your own product for resale or redistribution.
- Uploading files containing malware, deceptive or infringing content and inducing others to download them.
- If such behaviour occurs we may restrict access, keep evidence and enforce our rights where necessary.
Limitation of liability
To the maximum extent permitted by law we are not liable for any indirect, incidental, punitive or consequential loss. If any part of these terms is found invalid or unenforceable, the remaining parts stay in force.
Notices
Notices about these terms may be sent through the contact page. Updates are announced here; before relying on money-, health- or deadline-related calculations, please confirm the page and result fit your situation.
Updates and governing terms
The version on this page always governs. Continued use after an update means you accept it. Any dispute should first be resolved through friendly negotiation, and failing that, submitted to a competent body where the site operator is based.

FAQ
Can I use these tools at work?
Yes. Personal, work and commercial use are all allowed; only scraping, abuse and bulk content copying for a competing site are not.
What if a calculation looks wrong?
Tell us through the contact page with the page name and your input, and we will check the formula. Until then, treat results as a reference and verify anything important yourself.
