1. Our approach
Speaker Draft (the “App”) processes and stores speaker projects, driver information, enclosure dimensions, ports, horns, notes, and settings on the user's device. Sinrin Works does not collect personal information or usage data through the App.
2. Data we collect
The App does not collect data.
- There is no account registration or sign-in.
- The App does not use advertising, analytics, usage analytics, crash analytics, or tracking SDKs.
- The App does not access names, email addresses, location, contacts, photos, device identifiers, or purchase history.
- Projects are not sent to a proprietary server, and the App does not provide cloud sync.
3. Information stored on your device
Projects, design values, notes, current selections, language preferences, and other settings are stored locally on your device and are not sent to Sinrin Works. Data may be lost if the App is deleted, the device fails, or the device is erased.
4. External links
The App may show links to driver sources or support information. A link opens in an external browser only after the user selects it. External websites operate under their own privacy policies.
5. Website and web calculators
The enclosure and port calculators on this website run in your browser. Values entered into the calculators are not sent to or stored by Sinrin Works. The web server or hosting provider may temporarily process standard access logs for security and operations.
6. Contacting us
If you contact us by email, we receive your email address and any information you choose to include in the message. We use this information only to respond to your request.
7. Changes to this policy
We may update this policy when the App, legal requirements, or service operations change. Material changes will be clearly noted on this page.
