Support

Email robert@threethreedigital.com for help with Cornerman. There is no contact form on this site. Do not include your password.

Sign-in and password messages are sent from accounts@mail.cornermantracker.com. That address only sends mail. It is not the support inbox, so a reply there will not reach anyone.

Sign in and email

  • Create an account with your email and a password of at least 8 characters.
  • If the app asks you to verify the email, enter the 6-digit code from the message when the message includes one. Some messages instead contain a link.
  • Use Forgot password on the sign-in screen. The reset message is sent to that same email. The screen can accept a code when the message includes one.
  • If a message does not arrive, check spam, then wait before asking for another. The authentication service limits how many messages it sends.

Quit dates and check-ins

  • Set a quit date for alcohol, cannabis, vaping, or more than one. Each substance has its own count.
  • A quit date can be in the past, today, or up to 30 days ahead.
  • A check-in is for the local day on the phone: mood, craving strength, optional triggers, and an optional note only you can read.
  • A setback starts a new count when you choose that. Earlier days are not erased, and missed days are not shown in red.

Corner and crews

  • You can use Cornerman without inviting anyone.
  • A crew holds up to four people, including you. That means up to three other people.
  • You can be in more than one crew.
  • Leave a crew from the crew screen. Your own counts, journal, and check-ins stay on your account.

Privacy and sharing

Sharing starts off. For each person, or for a crew, you can turn on the day count, milestones, today’s mood, whether you checked in, and, for a crew, the substances you track. Notes, reasons, journal entries, and craving strength stay private. Read the draft privacy policy for the current description.

Widgets

  • Add a Cornerman widget from the iOS Home Screen or Lock Screen widget gallery after the app is installed.
  • Lock Screen text can stay discreet. Substance names appear only if you turn that option on.
  • A widget opens the app. It does not save a check-in by itself.
  • If a widget looks empty, open the app once while you are signed in so it can refresh.

Delete an account

In the app, open Account, then delete account. Enter your password. Confirm in the system dialog. There is no shorter path. Deletion removes the sign-in and the personal rows tied to it. It is not a promise that every backup or email copy disappears at once.

If you need help now

Cornerman does not provide crisis counseling or medical care.

  • In the United States, call or text 988, or chat at 988lifeline.org. You do not have to be in immediate danger to contact them.
  • For treatment referral and information, call the SAMHSA National Helpline at 1-800-662-4357 (TTY 1-800-487-4889). SAMHSA describes it as free, confidential, and available all day. Details are on samhsa.gov.
  • If you may be at risk from withdrawal, contact a doctor or local emergency services.
