Privacy Policy
Last updated: 2026-11-11 · Liu Guangkai · https://contour.niamori.ai
This Privacy Policy explains what personal data Contour collects, why, and what choices you have. In short: your images never leave your device, and we collect only what is needed to run the site.
1. Who We Are
Contour (https://contour.niamori.ai) is operated by Liu Guangkai, the controller of the personal data described in this policy. Contact us about privacy at support@niamori.ai.
2. Your Images Stay on Your Device
Images you convert are decoded, traced, and exported inside your web browser. They are not uploaded to our servers, and we cannot see them or their results. Closing the page discards them.
3. Information We Collect
- Visit statistics: Cloudflare Web Analytics counts page views, referring sites, browser, device type and country without cookies and without building a profile of you.
- Technical logs: when your browser loads the site, our hosting provider processes your IP address, user agent and the requested URL to deliver the page, protect against abuse, and fix errors.
- Account data (only if you create one): your name, email address, a salted hash of your password, your sign-in sessions with their IP address and user agent, and the status of your subscription. Payment details are collected by our Merchant of Record, not by us.
- Messages you send us: your email address and whatever you write.
4. How We Use Information
- to provide the Service and the plan you chose (contract);
- to keep the Service secure and reliable and to understand how it is used (legitimate interests);
- to answer your messages and handle billing, refunds, and disputes (contract and legal obligations);
- to meet tax, accounting, and other legal obligations.
5. Cookies and Local Storage
We do not use analytics, advertising, or tracking cookies. Your browser's local storage remembers your color scheme preference. If you sign in, a strictly necessary session cookie keeps you signed in until you sign out or it expires.
6. Sharing and Service Providers
We do not sell or rent your personal information, and we do not share it for advertising. We share it only with providers that run the Service for us, under their terms and privacy commitments:
- Cloudflare — hosting, database, Web Analytics, and email routing (privacy policy).
- Resend — sending account emails such as verification, password reset, and billing notices (privacy policy).
- Google (Gmail) — receiving the emails you send to our support address (privacy policy).
- Waffo Pancake (Waffo.com Limited) — checkout, payment processing, taxes, receipts, and refunds. As Merchant of Record it acts as an independent controller for the payment data it collects (waffo.ai).
We may also disclose information when required by law or a valid legal request, to protect the rights and safety of users and the Service, or as part of a business transfer with notice to you.
7. Retention
- Images and results: never stored by us.
- Technical logs: up to 30 days.
- Abuse-protection counters (IP address): up to 24 hours.
- Account data: until you delete your account from your account page or ask us to.
- Payment records: as long as tax and accounting law requires.
- Support emails: up to 24 months after the conversation ends.
8. Security
All traffic is encrypted with TLS, and passwords are stored only as salted hashes. Because your images are processed on your own device, they are never exposed to our infrastructure.
9. Your Rights
Depending on where you live (for example under the GDPR or the CCPA), you may have the right to access, correct, delete, or export your personal data, to object to or restrict its processing, and to complain to a data protection authority. Email support@niamori.ai to exercise these rights; we answer within 30 days.
10. International Transfers
Our providers may process data in countries other than yours. Where required, transfers rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.
11. Children
The Service is not directed to children under 16, and we do not knowingly collect their personal data. If you believe a child has given us personal data, contact us and we will delete it.
12. Changes to This Policy
We may update this policy. We will change the date at the top and, for material changes, notify subscribers by email before they take effect.
