Support
Help with the C!NK app and C!NK e‑ink displays.
Contact
Email support@cartouche.ink. Include your company name and, for display problems, the display's name (the C!NK‑XXXX code on its sticker). We reply within one business day.
Signing in
- No sign‑in link? Check spam for an email from hello@cartouche.ink. Links expire after an hour; request a new one from the app.
- "This email isn't part of a company yet." Your company's owner or admin needs to invite that address from Settings → Account. Cartouche sets up the first owner when a company is created.
Connecting to a display
- Press the orange button on the Screen tab, then hold the top of your phone against the orange dot on the display.
- "Registered to another company." Each display is locked to the company that added it. Only phones signed in to that company can change it.
- "Sign in to connect." You must be signed in to control displays.
- The display shows a small dot in the corner while a phone is connected, and disconnects by itself after a few minutes idle.
Displays
- Adding a display: Screen tab → Add C!NK → type the four characters from the display's welcome screen → Write Tag → hold your phone to the orange dot. Admins only.
- Battery: a mark in the display's top‑left corner means it needs charging. A full charge takes about four hours over USB‑C and lasts over a week of normal use.
- Firmware: updates ship inside the app. Connect to a display, open its info page, and tap Update if one is offered.
