Terms of Use

DaysLeft

Effective date: 2026-05-29

• ·When you enter lifestyle and health-checkup values, DaysLeft shows an estimated biological age and a distribution (range) of remaining time, based on public life tables and open research.
• ·No one can predict an individual's exact time of death. This service presents results only as a confidence interval (range) rather than a single point, and people in the same circumstances can see very different results.
• ·The result is a mirror to help you reflect on your behavior, not a prophecy that fixes the future.

• ·To the extent permitted by applicable law, the operator is not liable for decisions you make based on the results of this service, or for their consequences.

• ·Paid plans are currently unavailable. When sales reopen, they will be sold and processed by the Merchant of Record named at checkout, which will appear as the seller on your receipt and handle billing and applicable taxes.
• ·Auto-renewal, disclosed up front: monthly and annual subscriptions renew automatically at the end of each billing period at the then-current price. The renewal terms are shown at checkout before you pay, and you'll be notified before any trial converts to a paid subscription.
• ·You can cancel at any time; cancellation stops the next renewal and you keep access until the end of the paid period. No penalties, no remaining commitment.
• ·Lifetime is a one-time payment, not a subscription — it never renews or charges again.

Payments are currently paused. Before sales reopen, checkout will identify the Merchant of Record and disclose renewal and cancellation terms. Lifetime will remain a one-time payment and will not renew.

Subscriptions and Lifetime purchases are refundable within 14 days of purchase. The full policy, including how to request a refund, is in the Refund Policy. Nothing in these terms limits non-waivable consumer rights under applicable law.

• ·A key remains valid for the period you paid for (or indefinitely for Lifetime). A refund deactivates the associated key.
