Privacy Policy
Last updated: 2026-06-03
At Print Shuttle, your privacy is our core value. This Privacy Policy explains our approach to data collection and processing when you use print.shuttlelab.org.
Information We Collect
Print Shuttle does not collect, store, or transmit any of your design files, data inputs, or personal information. All operations — canvas editing, Excel parsing, barcode generation, and PDF export — occur entirely within your web browser using JavaScript libraries (Fabric.js, SheetJS, bwip-js, jsPDF). Your data never leaves your device.
Local Storage
Print Shuttle uses your browser's localStorage to store your preferences, such as theme selection (light/dark/system) and language settings (English/Chinese). This data remains on your device and is never transmitted to our servers.
No Server Processing
Unlike cloud-based design tools, Print Shuttle performs all operations locally in your browser. There is no server-side processing, no file uploads, and no temporary storage on remote servers. This design ensures complete privacy for your designs and business data.
Third-Party Subprocessors
Print Shuttle uses the following third-party services as data subprocessors: (1) Cloudflare — hosting and content delivery. Cloudflare may collect standard web server logs (IP address, browser type, access time) as part of normal CDN operation. We do not use analytics trackers, advertising networks, payment processors, or any other third-party services that collect user data. Your design files and data are never transmitted to any third party.
Cookies
Print Shuttle does not use cookies. All user preferences are stored in localStorage, which is not transmitted to our servers.
Children's Privacy
Print Shuttle does not knowingly collect any personal information from children under 13. Since we do not collect any personal data at all, our service is safe for users of all ages.
Changes to This Policy
We may update this Privacy Policy periodically. Any changes will be reflected in the 'Last updated' date above. Your continued use of Print Shuttle after changes constitutes acceptance of the updated policy.
Your Rights
Since Print Shuttle does not collect or store any personal data, there is no personal data to access, modify, or delete. All your design files and data remain exclusively on your device. If you have questions about your rights under GDPR (EU) or CCPA (California), please contact us at support@shuttlelab.org.
