Send a message
Tell us what you were trying to do and what happened. If the issue is in the Mac app, include your app and macOS versions if you know them. Please leave out your birth date and health answers.
Use the support form for questions, feedback or privacy requests.
I can't find my result email
Check your spam or junk folder. If your email has not arrived, contact support using the address you entered in the calculator.
How do I change my death clock target?
In the Mac app, click the menu bar countdown and open Settings, then Life plan. Choose a target age, population estimate or your own dates. The Longevity guide saves its result only when you choose "Use this date".
How do I stop app release emails?
Send a support message with the email address you want removed. You can also request removal of the registration record. Calculator result requests do not subscribe you to updates unless you selected that option.
Where can I download the Mac app?
The public Mac App Store link is being prepared. Request the release link on the homepage. Life Years Left requires macOS 13 or later on an Intel or Apple silicon Mac.
