Privacy Policy

Last updated: November 15, 2026

1. How images are processed

Images you upload for conversion are used only to generate the SVG vector result. The conversion service may be carried out by a browser-side or a server-side engine, depending on how the feature is implemented and how you use it. When you choose to publish to the gallery or upload an attachment, the relevant files are stored in server-side object storage. We do not use your images for anything other than conversion, and we do not provide them to third parties.

2. Information we collect

  • Account information: after you sign in through Alliance NO.1, we store the email address, nickname, avatar and alliance user ID held on the alliance side; this site never stores plaintext passwords;
  • Alliance data: to show your Credits and membership benefits, we query your Credit balance, account balance and lifetime membership status from the alliance main site (read-only — we never change them for you);
  • Usage statistics: tool name, action type, input format, output size and elapsed time, used to improve the product and to power the admin dashboard;
  • Technical logs: IP address and browser user agent, used only for security rate limiting and troubleshooting;
  • Cookies: a session cookie (sign-in state), a guest identifier cookie (anonymous usage statistics) and a language preference cookie (remembers the interface language you chose). No third-party tracking.

3. Data storage

Business data is stored in a MySQL database, session and rate limiting data in Redis, and images and attachments on remote servers. We do not sell your personal information to any third party.

4. Your rights

You can contact us at any time ([email protected]) to query, correct or delete your account and related data.

5. Policy updates

Any update to this policy will be published on this page, and significant changes will be announced on the site.
