+- **Kiosk tablets and QR codes:** in **Settings → Reporting links**, create a link. Open it on a shared tablet for a kiosk, or print QR codes for it from **Locations → QR codes**. Anyone can then report without an account; the link can't read anything and can be revoked at any time.

+- **Spanish:** use the language button (sidebar, sign-in page or kiosk header). The choice is remembered on that device.
