Privacy notice
Katori helps nutrition coaches follow their clients' meals over WhatsApp. This notice explains what we collect, why, who sees it and how to have it deleted. It is written for clients and for coaches.
Who is responsible
Katori is run by Sarthak Sachdeva as a sole proprietorship in Delhi, India (Udyam UDYAM-DL-02-0132001). For anything in this notice, write to Sarthaksachdeva8080@gmail.com. The same address is our grievance contact under India's Digital Personal Data Protection Act, 2023.
Your coach decides how your information is used in their programme. Katori processes it on the coach's behalf.
What we collect
- Your WhatsApp number, your name as shown on WhatsApp, and the coach you joined.
- The messages you send us: meal photos, voice notes and text.
- What we work out from them: the foods, rough amounts and nutrients, and the time of the meal.
- The answers you give when joining, such as your age group, food preference and allergies.
- Weight and water you choose to log.
- A record of your consent, with the exact wording you agreed to and when.
We only collect this after you have joined through your coach and said yes to the consent message. If you say no, we keep only the fact that you said no.
Why we use it
- To keep your food log and reply to you on WhatsApp.
- To compare your meals with the plan your coach wrote and show your coach your progress.
- To pass your questions to your coach and deliver their answers.
- To keep the service safe, for example to catch messages about health risks and point you to a doctor or your coach.
We do not sell your information, show you advertising, or use it to market anything else to you.
Who sees it
- Your coach sees your food log, photos, weight and the questions you send.
- Meta (WhatsApp) carries the messages between you and us.
- Google Cloud and Firebase store the data and run the service. Data is stored in Mumbai (asia-south1).
- Google's Gemini AI, through Google Cloud, reads meal photos, voice notes and text to work out what you ate. This processing may take place outside India. Google does not use this data to train its models.
We may also share information where Indian law requires it.
How long we keep it
- Voice notes are deleted once they have been read.
- Meal photos are kept while you are an active client and for 90 days after you leave, because coaches review them.
- Your food log and other details are kept while you are a client of your coach. If you leave or your coach stops using Katori, they are kept for 30 days so your coach can export them, and then deleted.
Your choices and rights
- Send STOP on WhatsApp at any time to stop using the service.
- Send DELETE MY DATA on WhatsApp, or write to us at the address above, to have your information deleted. To see or correct it, write to us. We delete it within 30 days, and usually sooner, and we tell your coach.
- You can withdraw your consent at any time. This does not affect anything already done before you withdrew it.
- If you are unhappy with how we handled a request, you can complain to the Data Protection Board of India.
Not medical advice
Katori is a logging tool. It does not diagnose, treat or give medical advice. Questions about health or medicine are passed to your coach, and you should ask a doctor before changing any medicine.
Age
Katori is for people aged 18 and over. We ask your age when you join and do not sign up anyone younger.
Changes
If we change this notice in a way that matters, we will tell you on WhatsApp before the change applies.
