Privacy policy

MRMF Print Queue is a self-hosted tool for sending 3D-print requests to a friend's 3D printer. It's run by an individual for use among friends. This policy describes what data the app handles, why, and for how long.

What we collect

• The name you type when submitting a request. Stored with the request so the printer owner knows whose job it is.
• The files you upload (STL, OBJ, 3MF, GCODE, STEP, or image preview). Stored on the printer owner's server only for as long as the job is active.
• The description you type describing what you want printed (color, infill, notes).
• A push-notification token if you grant permission on the mobile app. Used only to notify you when your request's status changes. Stored against your request.
• Your IP address, transiently, in server access logs and the rate-limiter's in-memory store. Not retained.

What we do not collect

• No analytics or behavior tracking.
• No advertising identifiers.
• No third-party SDKs that profile you (push delivery uses Expo's relay only).
• No location data.
• No contacts, photos, or files beyond what you explicitly attach to a request.

How long we keep it

• Files are permanently deleted from disk the moment the admin marks your request as DONE or REJECTED. A database row is kept noting that the files existed and when they were deleted, but the bytes are gone.
• Request records (name, description, status, file metadata) persist in the SQLite database until the admin deletes them. Contact the printer owner to request deletion of your records.
• Push tokens are tied to the request — when the request record goes, so does the token reference.

Who we share with

Nobody. The app talks only to the operator's own server. Push notifications transit Expo's relay (and Apple's APNs / Google's FCM) to reach your device — those services see the device token and the body of the notification, no more.

Your rights

Email or message the printer owner (whoever sent you the access code) to request:

• A copy of all data attributed to your name.
• Deletion of all data attributed to your name.
• Correction of an incorrect name on a request.

Security

The app is served over HTTPS with a Let's Encrypt certificate. The admin interface is gated behind a long, random access code. Files are stored on the operator's local server only; they never leave that machine.

Children

MRMF Print Queue is not directed at children under 13 and we do not knowingly collect data from them.

Changes to this policy

We'll update this page if data handling ever changes. Material changes will be flagged in the app on next launch.

Contact

The instance you're using is operated by the friend who invited you. For privacy questions or deletion requests, contact them directly.
