Privacy Policy
Moonraker Buddy (the “app”) is an iOS client that connects directly to 3D printers running Moonraker on your own local network. This policy explains exactly what data the app handles, where it goes, and what it does not do.
Summary
- The app does not collect, sell, or share personal data with advertisers.
- The app contains no analytics SDKs, no tracking, and no advertising identifiers.
- Printer connection details and print history stay on your device.
- The only time data leaves your device is if you (a) voluntarily submit the in-app feedback form, or (b) make a purchase through the App Store.
Information the App Stores on Your Device
To talk to your printer, the app stores the following on your device only:
- Printer configuration — printer name, IP address or hostname, port, and group label, stored in the iOS user defaults database.
- Authentication credentials — Moonraker API keys, and JWT access/refresh tokens when you sign in with a username and password, stored in the iOS Keychain.
- Print history snapshots — cached print state used to power Live Activities, background refresh, and notifications.
- Preferences — settings such as Live Activity toggles and notification preferences.
This data never leaves the device unless iCloud Backup is enabled in iOS, in which case it is included in your encrypted device backup as managed by Apple.
Communication With Your Printer
The app sends requests directly from your iPhone or iPad to the IP address you configured for your printer, typically over your local network. It uses the Moonraker HTTP and WebSocket APIs and, when configured, the printer’s MJPEG webcam stream. Anthropic, the developer, and any third parties have no visibility into this traffic.
Notifications and Live Activities
If you enable notifications, the app uses Apple’s local notification system to alert you about print events (completion, errors, temperature shutdowns, etc.) based on data fetched from your printer. Live Activities use the same on-device data. No notification content is sent to a third-party push service.
Background Refresh
If you enable Background App Refresh, iOS may wake the app periodically so it can poll your printer for state changes and update Live Activities or trigger local notifications. This polling only contacts your printer’s address.
Optional Feedback Form
The app includes an optional feedback form. If you choose to submit it, the message is sent over HTTPS to Resend (resend.com), which delivers it as an email to the developer. The following fields are transmitted:
- Any name you enter (optional).
- Any email address you enter (optional, used only so the developer can reply).
- The message text you enter.
- The app version and build number.
If you do not use the feedback form, no message data is ever transmitted. See Resend’s privacy policy at resend.com/legal/privacy-policy.
Purchases
In-app purchases are handled entirely by Apple’s StoreKit. The app does not see your payment details. Apple’s privacy policy applies to those transactions: apple.com/legal/privacy.
What the App Does Not Do
- It does not include third-party analytics or crash reporting SDKs.
- It does not use the Advertising Identifier (IDFA) and does not request App Tracking Transparency permission.
- It does not read your contacts, photos, calendar, location, or microphone.
- It does not sell, rent, or share data with advertisers, data brokers, or any other third party.
Children
The app is not directed at children under 13 and does not knowingly collect data from them.
Data Retention and Deletion
All on-device data is removed when you delete the app from your device. Feedback emails you have voluntarily sent are retained in the developer’s mailbox for support purposes; you may request deletion at any time via the in-app feedback form.
Your Rights
If you are in the UK, EU, or another region with data protection laws (UK GDPR, GDPR, CCPA, etc.), you have the right to request access to, correction of, or deletion of any personal data the developer holds about you. Because the app collects no personal data on its own, such requests will typically only relate to feedback emails you have sent.
Changes to This Policy
If this policy changes materially, the updated version will be published at the same URL with a revised “Last updated” date.
Contact
Questions or requests about this policy can be sent using the feedback form inside the app (Settings › Support › Send Feedback).
