Privacy Policy

Last updated: September 2026

Vimmi is your AI nutrition coach. This policy explains what we collect, why, and the controls you have over your data. The short version: your health data belongs to you. We don’t sell it, and you can export or delete everything from inside the app at any time.

What we collect

  • Account details - the email or sign-in method (Apple, Google or email) you use to sign up, and your chosen username.
  • Your logs - food, water, weight, workouts and activity, supplements, sleep, mood, energy, skin, digestion, cycle and progress photos, plus how you enter them (voice, photo, text or barcode).
  • Coaching conversations - voice sessions and chat messages, which we use to answer you and to keep coaching consistent.
  • Apple Health data (iOS only) - steps, sleep, weight and workouts you choose to sync, with duplicates removed.
  • Approximate location, rarely - only when you ask for nearby restaurant suggestions; it’s rounded, used for that one request, and never stored.
  • Device and diagnostic data - app version, device type and crash logs so we can fix things.

How we use it

  • To run the app: logging, nutrition analysis, coaching, insights, reminders and streaks.
  • To sync across your devices and to Apple Health where you’ve allowed it.
  • To improve Vimmi - for example, which foods get corrected most often - in aggregated form.
  • To handle support requests.

We do not sell your personal data or share it for advertising.

Voice and AI processing

Voice logs and coaching replies are processed by our AI providers to transcribe, understand and respond. They don’t keep your data to train their models. Your spoken words also appear as live captions so you can always see what was heard.

What you control

  • Export everything - request a complete copy of your data (JSON by email or CSV download) from inside the app.
  • Delete everything - delete your account in-app and all of your data goes with it, including backups on our normal rotation.
  • Apple Health - disconnect sync any time in iOS Settings; deleting data on one side removes it on the other.
  • Notifications and nudges - mute any nudge category by voice or in settings; reminders respect your quiet hours.

Data retention

We keep your data while your account is active. Delete your account and it’s removed from our live systems; backups roll off on their normal cycle. Aggregated, de-identified statistics can’t be traced back to you.

Children

Vimmi isn’t directed at children under 13, and we don’t knowingly collect their data.

Security

Data is encrypted in transit and at rest. Access is limited to the people who need it to run the service. No system is perfect, but we take protecting health data seriously.

Not medical advice

Vimmi is a wellness companion, not a medical device. It doesn’t diagnose or treat conditions. Talk to a clinician about medical decisions - especially around pregnancy, eating disorders and supplement safety.

Changes

If we change this policy materially, we’ll tell you in the app before the change takes effect.
