Privacy

Your data is yours.

Short version: we collect the minimum required to run the product, we never sell your data, and we make export and deletion easy.

What we store today (Phase 1)

The Phase 1 surfaces — peptide library, calculator, reconstitution guide, flashcards — work without an account. The only data stored is on your own device:

  • Your last-used calculator inputs and chosen syringe type (localStorage).
  • Your flashcard review history and spaced-repetition state (localStorage).
  • That you've acknowledged the disclaimer modal (localStorage).

Clearing your browser storage clears this. We have no copy on our servers.

What we will store when accounts ship (Phase 2+)

When auth, stack tracking, and dose logging launch, we will store:

  • Your email address (for magic-link sign-in).
  • Profile information you choose to provide — goals, age range, sex, weight range, allergies, current medications, conditions, experience level, clinician involvement.
  • Your stack: peptides, doses, schedules, vials on hand, reconstitution details.
  • Your dose log, side-effect log, and reminder preferences.
  • Phase 3+: your biomarker entries, lab PDFs you've uploaded, and AI insights generated from this data.

Sensitive fields (lab values, dose logs, biomarker data) are encrypted at rest. We log access to these tables for audit.

What we will never do

  • Sell, rent, or license your data to third parties.
  • Use your data to train external AI models without your explicit opt-in.
  • Share clinician-relevant data with a clinician or third party without your consent — your doctor-ready summary, when it ships, is something you generate and share, not us.

Cookies and analytics

We use a privacy-respecting product analytics tool (PostHog) and error tracking (Sentry). Both are configured with cookieless tracking where possible. EU users are presented with a consent prompt before any analytics events fire.

Export and deletion

When accounts ship, every account will have a one-click data export (JSON) and a one-click account deletion endpoint. Deletion removes your data from production within 30 days and from encrypted backups within 90 days.

Children

Juno is intended for adults (18+). We do not knowingly accept accounts from anyone under 18. AI features will refuse to advise on pediatric peptide use.
