Privacy Policy


Last Updated: November 2, 2026

"Labelme.io," "we," "us," or "our" means Kentaro Wada, trading as Labelme.io. This Privacy Policy explains what personal data we collect when you use our website (https://labelme.io) and the Labelme desktop application, why we collect it, and who else processes it.

1. The Labelme Desktop Application

The application uploads none of your images or annotations. It checks your license key offline and does not check for updates. It goes online to download the AI models you choose and, only if you agree when it asks, to send usage data (see Section 2). Model files come from our download server on Cloudflare or, if that fails, from the host that publishes the model, such as GitHub or Hugging Face. These hosts see your IP address as any website does.

If you connect an AI agent, such as ChatGPT or Claude, the application gives that agent's app what it asks for: the open image, its file path and the annotation file's path, your labels, and each shape's label, points, flags, and description. The agent's provider handles this data under its own privacy policy. An agent that runs its model on your computer keeps it there.

2. Information We Collect

  • Account: your name, email address, and password, which we store only as a hash. We also store your plan, your license's update period, and which of our emails we have sent you. When you sign up, we store how your browser first reached the website: the site that referred you, the first page you opened, the date, and any campaign tags in the link. We send the same details to PostHog with your sign-up and your purchases, to learn which sources lead to sales. If you buy before you have an account, the checkout passes them to Paddle so that we can store them with the account the purchase creates.
  • Purchases: Paddle processes your payment. We receive your email address, what you bought, and the amount. Paddle's purchase notice also includes your card type, last four digits, expiry, and cardholder name, which we do not store. We never receive your full card number or security code. To measure sales, we send Google Analytics and PostHog what you bought, the amount, tax, any discount code, the order ID, and the payment method type.
  • Application usage data, only if you agree to share it: when you open the application, see your trial end, click Buy, or activate a license key, with the application's version, your operating system, and the days left in your trial. PostHog receives it keyed by a random ID, never with your images, annotations, labels, or file paths. When you click Buy, the page that opens links that ID to your account. You can stop sharing at any time from the application's menu.
  • Website usage: Google Analytics and PostHog record the pages you visit, the buttons you click, the page that referred you, your browser and device, and an approximate location derived from your IP address. PostHog also records sessions on the website. It masks text you type and removes email addresses from page addresses before anything leaves your browser. When you are signed in, PostHog links this activity, including session recordings, to your account.
  • Messages: emails you send us, including any attachments. They are kept confidential and used only to support you.

3. How We Use Your Information

  • To run your account and license, and to deliver the application.
  • To send emails about your account, trial, purchase, and major releases.
  • To answer your questions and give support.
  • To understand how people use the website and improve it.
  • To comply with the law and prevent fraud.

4. Who Processes Your Information

We do not sell or rent your personal information.

Paddle (Paddle.com Market Limited) is our merchant of record. It sells you the license and handles checkout, payment, tax, and invoices under its own privacy notice (https://www.paddle.com/legal/privacy).

These providers process your information on our behalf:

  • PostHog (PostHog, Inc.), for website analytics, session recording, and sales measurement.
  • Google Analytics (Google LLC), for website analytics and sales measurement.
  • Cloudflare Turnstile (Cloudflare, Inc.), to block automated sign-ups. It processes your IP address and browser information.
  • Mailgun (Mailgun Technologies, Inc.), for sending email.
  • Our hosting, storage, and email providers, to run the website and our support inbox.

We may also disclose information when the law requires it, or as part of a merger or sale of the business.

5. Cookies

We use a cookie to keep you signed in. A second cookie of ours carries short notices between pages and remembers how your browser first reached the website. Google Analytics and PostHog set cookies and use your browser's storage to recognize returning visitors. Paddle sets its own cookies during checkout. You can block or delete cookies in your browser settings; the website still works without the analytics cookies.

6. How Long We Keep It

We keep your account information while you have an account. We keep support emails so we can help with related questions later. You can ask us to delete any of it at any time.

7. Data Security

We use reasonable technical and organizational measures to protect your data. No system is completely secure, so we cannot guarantee absolute security.

8. Your Rights

Depending on where you live, you can ask us to:

  • Access: give you a copy of the data we hold about you.
  • Correction: correct inaccurate data.
  • Deletion: delete your data, unless the law requires us to keep it.
  • Objection: stop using your data for a particular purpose.

To exercise these rights, contact us at support@labelme.io.

9. International Data Transfers

We are based in Japan, and our providers process data in other countries, including the United States. Our agreements with PostHog, Google, Cloudflare, and Mailgun protect these transfers with the EU Standard Contractual Clauses or the EU-U.S. Data Privacy Framework.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The latest version is posted on this page with a new "Last Updated" date.
