Privacy notice

CommonGround helps members of the Imperial MBA cohort find each other to collaborate. It is run by cohort members, not by Imperial College London.

What we store

• Your email address, used to sign you in and, when email delivery is configured, notify you about connection requests.
• The profile you write: name, programme, headline, ideas, background, interests, skills, manually entered work/education, LinkedIn and contact note.
• Ideas you post, connection requests you send or receive, and reports you make.
• Anonymous questionnaire drafts expire after one hour and are removed by scheduled housekeeping; signing in transfers your answers to your account.
• Your 15 questionnaire answers, your optional self-reported Myers-Briggs type, and your LinkedIn identity (name, email, identifier and photo URL when supplied), permission scope names and connection-test results.
• When you joined and last signed in. A session cookie keeps you signed in; there are no tracking or advertising cookies and no analytics.

Who can see it

• Signed-in members see your profile (except contact details) while it is visible.
• Your email, LinkedIn and contact note are shown only to people whose connection you have accepted, or who accepted yours.
• Moderators named by the organisers can see account lists and reports to keep the space safe.
• Raw questionnaire answers, your snapshot and Myers-Briggs type are private to you. Matches show an aggregate reason when preferences and values align.
• Matching runs on our own server. Your written profile and questionnaire are not sent to an AI service.

Service providers

WorkOS and LinkedIn handle LinkedIn sign-in and process the identity information needed for authentication. Standard LinkedIn sign-in provides basic identity details, not work history, skills or a public profile link. You enter professional details and your profile link yourself.

The app and database are hosted on Google Cloud in us-central1 (United States). WorkOS and LinkedIn may process identity data internationally. Your profile photo URL is stored privately; the app does not load external profile photos.

Signing out ends your CommonGround session. Deleting your account erases the app’s copy immediately; authentication records held by WorkOS or LinkedIn are subject to those providers’ retention policies. Contact the organiser if you need help with those records.

Your choices

• Hide your profile at any time from the “You” page.
• Download everything we hold about you as a file.
• Delete your account: your data is erased immediately and is gone from backups within 30 days.
• Accounts unused for 365 days are deleted automatically.

Lawful basis: your consent, given when you create a profile. You can withdraw it by deleting your account.
