Terms of Service
Who we are
Photo to Line Drawing is operated by Kuang Haibin (旷海滨), a sole proprietor established in Changsha, Hunan, China. These terms form the agreement between you and us for the use of https://phototolinedrawing.com and any related pages or APIs (the "Service"). You can reach us at support@phototolinedrawing.com.
What the Service does
The Service converts a photograph you upload into a line drawing suitable for printing or colouring, and returns a watermarked preview plus, once unlocked, scalable vector (SVG), raster (PNG) and paper-sized PDF files. Processing is automated. Filled contours are produced by tracing regions, not by centreline pen plotting.
Accounts
Signing in requires a Google account. You must be at least 13 years old, and at least 16 years old or have guardian consent where the law of your country requires it. Keep access to your Google account secure; activity performed through your signed-in session is treated as yours. One person should not maintain multiple accounts to obtain repeated free allowances.
Your uploads and acceptable use
Upload only photographs you own or otherwise have the right and consent to process, including consent from any person identifiable in the photo. Do not upload unlawful material, images of minors without guardian consent, identity documents, medical records or other sensitive personal data. Do not attempt to bypass usage limits, probe the service for vulnerabilities, resell raw access, or submit automated bulk jobs outside an agreed arrangement.
Free uses and credits
A verified account receives five free uses in total. They do not reset daily and they produce watermarked preview files only. Paid credits are sold either as a recurring subscription or as a one-time pack, and a pack can be used without subscribing. One standard successful paid task consumes one credit; repeat downloads of the same result stay free while the file is retained. Credits have no cash value, are not transferable, and expire only as displayed at checkout.
Payments, renewals and cancellation
Payments are processed by PayPal, and by Waffo where that option is offered. Subscription payments renew automatically for the billing period you selected until cancelled. You may cancel at any time; cancellation stops future renewals and leaves access in place until the end of the paid period. Cancelling a subscription does not delete unrelated one-time packs. Prices, taxes and the billing period are shown before you confirm a purchase.
Refunds
Refund requests are handled under our Refund Policy, which allows a request within fourteen days of a first subscription payment or one-time pack purchase. A task that fails or times out releases the reserved use or credit automatically; that release is not a monetary refund.
Your content and the licence you give us
You keep ownership of the photographs you upload. You grant us a limited licence to store, transmit and process that content, and to deliver the output, for the sole purpose of providing the Service. We do not use your uploads or outputs as public examples or marketing material without separate documented permission. We claim no exclusive copyright in the generated output, and we do not promise exclusivity, a perfect likeness, or fitness for a particular manufacturing process.
Limitations of automated output
Generated line work can contain geometric errors, missing detail or false contours. Inspect proportions, line continuity and print suitability in your own software before printing, engraving, cutting or any production use. The Service is not a substitute for professional prepress, engineering or safety review.
Availability and changes
We may modify, suspend or discontinue features, and may interrupt the Service for maintenance or capacity reasons. Where a change materially reduces a paid entitlement, we will provide a reasonable remedy such as a credit or refund.
Liability
To the extent permitted by law, we are not liable for indirect or consequential loss, lost profit, or loss arising from production use of generated output. Our total liability for a claim relating to the Service is limited to the amount you paid us in the twelve months before the event giving rise to the claim. Nothing in these terms excludes liability that cannot lawfully be excluded, including your statutory consumer rights.
Termination
You may stop using the Service at any time and request deletion of your account. We may suspend or terminate an account that breaches these terms, that we are required to act against by law, or that presents a security or abuse risk. Where practical, we will explain the reason and allow you to request your data first.
Governing law and disputes
These terms are governed by the laws of the People’s Republic of China, and the courts of Changsha, Hunan, China have jurisdiction, without prejudice to mandatory consumer protection rules in your country of residence, including any right to bring proceedings locally. Contact support@phototolinedrawing.com first so we can try to resolve the issue directly.
Changes to these terms
We may update these terms as the Service changes. The current version is always published on this page with its effective date. Material changes affecting paid entitlements will be announced before they take effect. Last updated November 10, 2026.
