1. Where the numbers come from
Every calculation on the site rests on two inputs you can change at any time: your current age and a life expectancy figure. From those we derive a number of remaining days and express it in weekends, springs, visits and other units. The default life expectancy is a starting point, usually taken from published population averages.
That means the result is arithmetic, not prediction. It takes no account of your health, family history, where you live, your occupation, your medical care or any other individual factor. Real lives run both far shorter and far longer.
2. Not professional advice
The content of this site is for general information and personal reflection only. It does not constitute, and is no substitute for, medical, mental health, legal, financial, insurance or any other professional advice. Do not make significant health, financial or legal decisions on the basis of these figures, and do not delay or forgo medical care because of them. Consult a qualified professional instead.
3. A note on how this may feel
This site talks about time and loss, and that can be hard. If any of it leaves you feeling acutely sad, anxious or hopeless, close the page and talk to someone you trust. If you are in distress that feels unbearable, please contact a mental health or crisis support service in your area, or your local emergency services.
This site is not a counselling service and has no capacity to respond to a crisis.
4. Information about other people
You can write down the names of friends and family and add their photos. It is up to you to use that information reasonably, particularly if you choose to publish a share card containing someone else's name. This content is stored on your device and we cannot manage it on your behalf.
5. Accuracy and availability
We try to keep the content and the calculations correct, but we do not warrant that the information on the site is free of errors, always current, or continuously accessible. Features may change or be withdrawn at any time.
6. Third-party content
The site may contain links to external sites or third-party advertising. That content is outside our control, its presence is not an endorsement, and we accept no responsibility for its content, accuracy or practices.
7. Loss of data
What you write is stored only in your browser. Clearing browser data, uninstalling the browser, changing device, using a private window or automatic browser cleanup can all remove it permanently. We hold no copy and cannot recover it. Save anything important elsewhere.
