Your model stays private.

SLCER uses an uploaded model only to analyze and prepare your requested print. The model and project record stay in private project storage so you can return to them. Temporary slice-job inputs and generated results use separate private storage and expire after the configured retention window, which defaults to 24 hours.

Voice privacy

The microphone never starts automatically. Audio and transcripts are not logged by default. A selected speech provider receives only the information needed for the active voice session.

Speaking a phone number or profile name uses the browser's speech service, which may process audio on the device or through the browser vendor. Verification-code dictation is different: SLCER offers it only when the browser explicitly guarantees on-device recognition. The six digits go only into the visible, editable code field; SLCER does not repeat them aloud, add them to a transcript, or submit them until you activate Verify and continue.

Account privacy

Phone verification is used for sign-in. Phone numbers are processed by Firebase Authentication and are not used as public profile information.

Email-link sign-in is the no-CAPTCHA alternative. SLCER stores the email address in this browser only while the one-time link is pending, so the field can be prefilled when you return. It is removed after successful completion. On another device, you enter the address again to prevent a forwarded link from being reused by someone else.
