This privacy policy explains how our website, Excalidraw by Theducbui, collects, uses, and protects your information when you use our service. We may collect limited personal data for authentication purposes.
Excalidraw by Theducbui collects your email address for authentication purposes when you sign up or log in using our authentication system (powered by better-auth). Core functionality operates client-side within your browser, but email data is stored server-side to facilitate secure authentication. We do not collect or store any other personal data unrelated to authentication.
We use your email address solely for authentication, account management, and to enable secure access to the website's features. We do not use your data for marketing, analytics, or any other purposes.
Your email address is stored securely in our database with industry-standard encryption and access controls to protect against unauthorized access. Any data generated during use (like file metadata or preferences) is stored locally in your browser and is never transmitted to us, except for the email used in authentication. We retain your email only as long as necessary for providing the service or as required by law.
We do not sell, trade, or otherwise transfer your personal information to outside parties, except as required for authentication processes or to comply with legal obligations. The only data shared is with Google's servers as necessary to facilitate the Drive integration functionality.
You have the right to access, update, or delete your email address and associated data at any time through your account settings. For deletion requests or other inquiries, contact us at the email below. We comply with applicable data protection laws, including rights under GDPR or CCPA where relevant.
We may update our Privacy Policy from time to time. We will notify you of any changes via email if you have provided one.
