Your life, in chapters

A move, a relationship, a course of study, a job, a project: these chapters can overlap. A timeline gives them a shared scale without forcing them into a résumé.

Make a timeline, add your chapters, and choose how far the view extends. That horizon is a setting you control, not a prediction of how long you will live. You can keep the result on your device, share a link, or embed it on a website. No account is required.

Give your agent a few milestones, a résumé, or an optional LinkedIn profile. The Lifecharts skill helps it turn that material into an editable chart and a link you can open here. A birthday is optional; a career, a project, or a single chapter can have its own starting point.

Your agent should use only sources you authorize, keep uncertain dates approximate, and leave missing facts for you to fill in. Lifecharts does not fetch your LinkedIn profile or fill in personal history by itself.

Lifecharts, formerly Life Days Left, is an independent public project. Follow its original generation chart at @lifedaysleft ↗. The same project maintains the life chart maker and its original population-model references.

Saved drafts are stored in this browser. This is not an account or a cloud backup: clearing browser data can remove it, and another device does not automatically have a copy.

A full timeline link includes the dates and text you entered, including any birthday and chapter labels. Anyone who receives the link can read that content and pass it on. The link is encoded, not encrypted. Review your timeline before sharing it or publishing an embed, especially if it mentions other people.

Standard links keep the chart in the URL fragment, after the #. Browsers do not send that fragment to our server. These links have a generic Lifecharts preview when you paste them into another app.

The optional “Include a chart image in link previews” setting creates a link that sends your complete chart to our server so we can render its name and chapter bars for social previews. Link-preview services can read and cache the chart and image. Use it only for a chart you intend to make public. Both kinds of link are excluded from search; neither requires an account or loads analytics.

Changing your local draft does not change a link you already shared. Copies of that link remain readable; there is no account-based access control or recall. Being excluded from search results does not make a shared timeline private.

Older rounded snapshot links, such as /share/60-percent-ahead, work differently. They contain only a rounded percentage, without a birthday or chapter text. They remain available.

Anonymous site-health analytics runs only on the canonical lifecharts.io production host. PostHog receives cookieless page and performance events without person profiles, persistent identifiers, interaction autocapture, or session replay. Query strings and URL fragments are stripped. Full timeline viewers at /view and widgets at /embed do not load analytics. Older rounded share snapshots and unrecognized paths are recorded only as/private.

The project began as Life Days Left, with a daily chart comparing U.S. birth-year groups under one declared population model. The data and downloads remain available, along with the formula, sources, and limitations.

The personal timeline’s chosen horizon is separate from those population estimates. Neither is an individual prognosis. The research explainers remain withheld from search and public listings until they receive the required independent statistical review.

• Prefer primary research, official government tables, and the source authors’ own documentation. Link them beside the claim they support.
• Label the active model version and distinguish a source update from the daily passage of time.
• Keep publication and material-update dates visible. Do not refresh dates when the substance has not changed.
• State uncertainty and omitted variables in plain language. Do not turn observational associations into causal or personal claims.
• Correct calculations and source descriptions in the page where they appear, then update the model or article date when the change is material.

To flag a possible error, contact @lifedaysleft ↗ with the public page and a description of the issue. Do not send a personal timeline link unless you intend to share everything it contains. For a data correction, include the disputed value and its primary source.

Lifecharts is not a death clock, clinical tool, insurance model, financial plan, or individualized actuarial assessment. It cannot know how long a person will live and should not influence care or other high-stakes decisions.

Choose a horizon because it helps you arrange your timeline. Read the original model as a population illustration, with its assumptions in view.
