Ascendia accounts are for people aged 16 and over. Personalized calorie targets require adult eligibility at 18 or over. Sign-up asks for a date of birth and stores the year, and the same eligibility and agreement step applies to email and federated sign-in. A self-declared date is not identity verification. An ineligible account may be restricted with access to applicable export, deletion and billing recovery routes. See the Terms and Privacy Policy.
