本文件以英文提供；具有法律约束力的文本为英文版。

1. Information We Collect

TeachPen does not require an account. To activate and verify licenses, we process only the email address used at purchase and an anonymous device identifier for license verification (a hashed machine id). Annotation data and in-app usage content stay on your local device and are not sent to TeachPen servers.

2. Payment Information

Payment information such as card details is collected and processed by Paddle, the Merchant of Record. TeachPen does not access that information. Paddle's Privacy Policy applies to payment processing.

3. How We Use Information

We use collected information to activate and verify licenses, confirm purchases, provide support, and send purchase confirmation or verification emails.

4. Email Delivery

Verification codes, purchase confirmation emails, and support-related emails may be sent through Amazon SES.

5. Retention

License information is retained for the duration of the license. If you request deletion, we will delete the information unless retention is required by law.

6. Third Parties and Processors

TeachPen does not sell personal information. We use processors only as needed to provide the service, including payment processing by Paddle and email delivery through Amazon SES.

7. Your Rights

You may request access, correction, or deletion of your personal information by contacting hello@teachpen.com.

8. Cookies

The TeachPen landing site uses only essential cookies, such as language preference cookies. We do not use advertising tracking cookies.

9. Contact and Privacy Responsibility
