Delete your Mercify9 account

Last updated: November 10, 2026

You can delete your Mercify9 account at any time. This removes your account and the data linked to it, for both the Mercify9 app and mercify9.com, because they share one account. You can do it yourself in a minute, or ask us by email.

Option 1: Delete it yourself (fastest)

Sign in to the Mercify9 app or to mercify9.com.
Open your Profile (“My Profile”).
Scroll to Danger Zone and tap Delete My Account, then Yes, Delete My Account.
Confirm it is you. If you signed up with an email and password, enter your password and tap Confirm & Delete. If you use Google or Apple, sign in again in the Google or Apple window that opens.
Your account is deleted right away and you are signed out. Your saved data is removed with it.

Option 2: Ask us by email

If you can't sign in, or you would rather we do it, email us from the address on your account. Use the subject “Delete my account”. We may ask you to confirm the request from that address so nobody else can delete your account. We delete the account and its data within 30 days and email you when it is done.

Email info@mercify9.com

What we delete

– Your sign-in account (email address, name and sign-in method)

– Your profile details (name, optional phone number, personal motto and settings)

– Your saved calculator results

– Your article likes

– Records of the free files you downloaded

– If you signed in with Apple, we also ask Apple to remove Mercify9's access to your Apple ID

What we keep, and for how long

We keep usage statistics that do not include your name or email address. They help us understand how the app and site are used, and they cannot be used to rebuild your account. Error reports sent to our error tracking service are deleted automatically by that service after its retention period, which is 90 days or less. Emails you sent us, such as contact form messages, stay in our inbox unless you ask us to delete them.

The newsletter is separate from your account. Deleting your account does not remove a newsletter subscription. To stop the newsletter and remove your email from our list, email info@mercify9.com and we will remove it.
