Your health data in Yema
Yema is a food and weight diary, so it processes health data. Here we tell you which data, what for, who handles it, which permissions we ask for and what your rights are. It's a summary of the Privacy Policy, which has all the details.
Who handles it
Duvan Vargas, a private individual domiciled at Calle 32 #52b-150, Rionegro, Antioquia, Colombia, who develops and runs Yema. Write to us at soporte@tryyema.com or on LinkedIn (https://www.linkedin.com/in/duvandroid).
What health data we process and what for
Yema processes health data. The law calls it sensitive data (in Colombia, Brazil and Mexico), special category data (in the European Union and the United Kingdom) or consumer health data (in several U.S. states), and gives it stronger protection. This is Yema's:
| Data | Where it comes from | What for | Where it lives |
|---|---|---|---|
| Weight, height, goal weight, calorie and macro goals | You, or Apple Health or Health Connect (your scale's weight, and the height only if you choose to use it) | Your plan and your trend | Your phone and your account |
| Meals, water and exercise you log | You | Your diary and your rings | Your phone and your account |
| Pregnancy and breastfeeding | You | Calorie floors and foods to avoid | Your phone and your account |
| Conditions and medicines: diabetes, insulin or glucose-lowering pills, "-gliflozin" drugs, weight-loss medicines (GLP-1), high blood pressure, kidney or heart disease, weight-loss surgery | You | Keeping your plan safe: no deficit when it isn't advisable, a weight-loss goal that waits for your doctor, and care in what we suggest | Your phone and your account |
| A history of an eating disorder | You | Your plan has no deficit, no "high protein", and offers a numbers-free mode | Your phone and your account |
| Allergies, intolerances and celiac disease | You | Filtering what we suggest and warning you | Your phone and your account |
| How you eat: plant-based, no meat, halal, kosher, no pork… | You | Respecting it everywhere. It may reveal your beliefs | Your phone and your account |
| Workouts, active energy and steps | Apple Health or Health Connect | Spreading your day, your water and your protein, telling you when you moved more than usual (they don't change your goal) and letting Yema's suggestions take your day into account | Only on your phone (read each time). A summary goes to the AI with each suggestion (section 6) |
| Hours of sleep | Apple Health or Health Connect | Little sleep changes hunger and cravings | Only on your phone. A summary goes to the AI with each suggestion (section 6) |
| Height | Apple Health or Health Connect | If it's 3 cm or more away from your profile's, asking you once which one to use: Yema never changes it on its own | Only on your phone. It doesn't go to the AI |
| Food and water other apps log | Apple Health or Health Connect | Showing them apart so nothing counts twice: never added to what you log in Yema | Only on your phone |
| Menstrual cycle | You, or Apple Health or Health Connect | Explaining weight changes | Only on your phone |
| Mood | You, or Apple Health on iPhone | Understanding your cravings | Only on your phone |
| Blood glucose and blood pressure | Apple Health or Health Connect, only if you marked diabetes or high blood pressure in your profile (they start off and ask for their own yes) | Rules that run on your phone: they never go to the AI or to our server | Only on your phone |
| What Yema infers: what's left of your day, your trend, your adaptive goal | Yema, from the above | Your plan | Your phone and your account |
If you choose "On this phone only" mode (section 10), what says "Your phone and your account" stays only on your phone.
What always applies to this data:
- Giving it is optional. Because it's sensitive data, you aren't required to authorize its processing, and no feature that doesn't need it depends on you giving it. Each group has its own permission (section 10).
- We use it only to provide the service you ask for: your plan, your diary, your recipes, What to Order and Yema's answers.
- We don't sell it, use it for advertising or build profiles for advertisers, and we don't use it to make decisions about insurance, credit or employment.
- It never appears in what you share: Your month and badges carry no figures, no weight and no health data.
- The Yema team can't see it. The database rules don't let anyone but you read it. For metrics the server only counts how many meals you logged, never which ones.
- Google only receives what's needed for the answer you asked for (section 6), and Google doesn't use it to train its models.
Your permissions
- Each group of health data has its own permission, with its own unticked box: your plan and diary in your account, your health, how you eat and your allergies, your cycle, your mood and Yema's AI. Before each one we tell you what data it is and what it's for.
- If you don't give a permission, Yema works just the same, only without that care. If you don't want to keep your plan in your account, you use Yema in "On this phone only" mode, with no copy in the cloud.
- You withdraw them whenever you want, as easily as you gave them, in More > Privacy. When you withdraw one, we delete that data from your account.
Your rights
You can know, update, correct and delete your data, ask for proof of the permissions you gave and revoke them, free of charge. In the app you see everything you log, correct it or delete it, and "Download my data" gives you a copy. For anything else, write to soporte@tryyema.com: we answer inquiries within 10 business days at most and claims within 15. If you're not satisfied, you can go to Colombia's Superintendence of Industry and Commerce (www.sic.gov.co) or to your country's authority.
You can delete your account and all your data at any time, in More > Privacy > Delete my account or at tryyema.com/borrar-cuenta (in Spanish for now).
If you live in the U.S.: Consumer Health Data Privacy Policy
For residents of Washington State (My Health My Data Act, RCW 19.373), Nevada (SB 370) or any other U.S. state with a consumer health data law. It's also published on its own page, tryyema.com/en/privacidad-salud, linked from the home page.
Controller: Duvan Vargas (section 1). Contact: soporte@tryyema.com.
- What consumer health data we collect: your weight, height, goal weight and targets; the meals, water and exercise you log; pregnancy or breastfeeding; your conditions and medicines; a history of an eating disorder; your allergies, intolerances and celiac disease; your way of eating; what Yema infers from that (what's left of your day, your trend, your adaptive goal); and, if you connect them, the weight, workouts and height from your phone's health app, and a summary of your workouts, steps, active energy and sleep that goes with each suggestion and that we don't keep. We don't collect your cycle, mood, glucose or blood pressure: they stay on your phone.
- Why we collect and use it: only to give you what you ask for: your plan, your diary, your recipes, What to Order and Yema's answers (sections 4 to 6 and 8 of the privacy policy).
- Where it comes from: from you and, if you allow it, from Apple Health or Health Connect.
- Who we share it with: only the processors that process it on our behalf (Google Cloud and Firebase, Vertex AI and, for emails, Resend), under contracts that forbid them to use it for anything else. We don't share it with third parties or affiliates (we have no affiliates). If we ever wanted to share it, we'd first ask for your separate consent.
- We don't sell it. Ever. Nor do we use geofences around places where health care is provided.
- Your rights: to confirm whether we collect, share or sell your health data; to access it, with the list of who we gave it to and how to contact them; to withdraw your consent; and to have it deleted, including from backups and from our processors. We reply within 45 days (we can extend by 45 more days by letting you know). It's free up to twice a year. You don't need to create an account to ask, and we won't discriminate against you for doing so.
- How to exercise them: in More > Privacy, at tryyema.com/borrar-cuenta or by writing to soporte@tryyema.com.
- Appeals: if we deny your request, reply to our email with "Appeal". We'll answer in writing within 45 days, with what we did and why. If we still don't agree, you can complain to the Washington State Attorney General (www.atg.wa.gov) or to your state's attorney general.
