Asympt.io is a health optimization tool operated from Denmark. We help healthy adults understand which areas of their health offer the greatest potential for improvement, based on published scientific evidence.
Assessment data (anonymous by default) — Age, sex, height, weight, and questionnaire responses are processed in your browser and are not stored on our servers unless you choose to create an account (future feature).
Email address (only if you provide it) — If you choose to save your results or subscribe to our newsletter, we collect your email. We use Resend (resend.com) to store and send emails. You can unsubscribe at any time.
Anonymous analytics — We use Vercel Analytics to count page views and assessment completions. This data is aggregated and cannot identify individual users. No cookies are used for analytics.
We process personal data under: Consent (Article 6(1)(a)) when you provide your email address, and Legitimate interest (Article 6(1)(f)) for anonymous analytics. Health questionnaire responses are processed client-side only and not transmitted in identifiable form.
Email data is stored by Resend, Inc. (US-based, EU-US Data Privacy Framework compliant). Analytics data is processed by Vercel, Inc. (same compliance). Assessment responses are not stored on any server — they exist only in your browser session.
