Delete Your Account

Applies to the website, the desktop app, and the iOS and Android apps

You can delete your CHIEFMATE account yourself, at any time, without asking us. Deletion is permanent. It removes your account and everything you entered under it.

1.Delete it yourself

Sign in at stemmaritimesystems.com/account with the same email you use in the app. In the phone apps, open More, then Account.
Scroll to Delete Account at the bottom of the page.
Enter your password, type DELETE in the confirmation box, and press I understand, delete my account.

Your account is deleted immediately. If you had an active subscription it is canceled at the same time and nothing more is charged.

2.What is deleted

Your login: email address and password hash.
Everything you entered: ship profile, vessel library, logbooks, positions and sights, voyage plans, stability conditions, crew schedules, rest hours, checklists, drills, credentials, documents and photos you uploaded, AI chat history, and your settings.
Your subscription record with us, and the subscription itself at Stripe.

3.What is kept, and for how long

Stripe keeps the invoice and payment records the law requires us to hold, for as long as tax and accounting rules require. Your card details were never stored by us. Web server logs that may contain your IP address are kept for up to one year for security, then discarded. Our nightly database backups are kept for up to 30 days, so a copy of a deleted account stays in those backups until they age out. Nothing else about you is retained.

4.If you cannot sign in

Use Forgot password first. If you no longer have access to the email address on the account, write to support@stemmaritimesystems.com and tell us the email the account was opened with. We will confirm it is you and delete the account within 30 days.

5.Deleting some data but keeping the account

Every record you enter can be removed from inside the app: delete a logbook entry, a vessel, a voyage plan, a document, or a photo from its own page. To have us clear a whole category for you, write to support@stemmaritimesystems.com.

6.Fleet seats

A crew seat issued by a fleet office is owned by that office. Deleting your own login removes your personal account; the vessel records stay with the fleet. A fleet office account cannot be deleted while it still has live seats. Pull the seats first, then delete the account.
