YolkHatchPrivacy Policy
Last updated August 2, 2026
This policy covers the YolkHatch iOS app and the nutrition professional portal at yolkhatch.com, operated by Summitview Land Holdings, LLC.
The honest summary, before the long version: YolkHatch handles sensitive health data — what you eat, your weight, your medication, your surgery. We do not sell it, rent it, or share it with advertisers, insurers, employers, or data brokers. There is no advertising SDK and no analytics SDK in the app.
1. What we collect
Account data
In the app, you sign in with Sign in with Apple. We receive a user identifier and an email address — which may be Apple's private relay address if you choose that option, in which case we never see your real email. In the professional portal, practitioners create an account with their name, email, password, and self-reported professional registration number.
You can use the app without an account. Without signing in, everything stays on your iPhone and nothing is sent to us. The account exists to sync across devices and to link with a nutrition professional.
Health data you provide
| Data | Why |
|---|---|
| Whether you use a GLP-1 medication or had bariatric surgery | Determines which mode of the app you see |
| Medication name and start date | Tracks your dose cycle in the daily log |
| Bariatric surgery type and date | Places you in the right post-op stage |
| Current and target weight | Goal calculation and progress |
| Whether you do strength training | Feeds the protein goal suggestion |
| Meals: time, description, protein, calories | The core of the app |
| Water intake, mood, symptoms, dose taken | Daily check-in — all optional |
Purchases
Subscriptions and coins are processed by Apple. We never receive, see, or store card numbers or payment details — only whether a subscription is active.
2. What we do NOT collect
- Your meal photos never leave your device.Recognition runs locally using Vision and Apple's on-device models. There is no image upload — we do not even operate file storage for it.
- Your location. The app never requests or uses it.
- Advertising and tracking. No ad SDK, no analytics SDK, no advertising identifier (IDFA). The app does not show the iOS tracking prompt because there is nothing to track.
- Apple Health data. We neither read from nor write to HealthKit.
3. Where data is stored
On your iPhone, always. If you sign in, a copy syncs to Google Firebase (Firebase Authentication and Cloud Firestore), our infrastructure processor. The database is hosted in the São Paulo, Brazil (southamerica-east1) region. Traffic is encrypted in transit and data is encrypted at rest by Google.
Database security rules are configured so that each person can only reach their own data — and, for practitioners, only the data of patients who linked themselves to them.
4. Who we share with
The professional you link to
If you enter a practitioner's code in the app, they can see your daily log (meals, protein, calories, water) and set your goals. You start that link — nobody can reach your data unless you enter their code.
To end the link today, email info@summitviewland.com. We remove the access and confirm by email.
Service providers
- Google (Firebase) — database and authentication hosting.
- Apple— sign-in, purchase processing, and iOS speech recognition when you log water by voice. In that specific case the audio snippet may be processed on Apple's servers under Apple's policy. You can always type instead of speaking.
- Open Food Facts — a public, open food database. When you search for a food by name, the search text is sent to their service. No account, health, or identifying data is sent with it.
Never
We do not sell, rent, or trade your data. We do not hand it to advertisers, insurers, health plans, employers, or data brokers. If the company is ever sold or merged, we will notify you before any transfer.
5. How long we keep it
As long as your account exists and you want us to. There is no minimum retention period: the moment you ask for deletion, we delete. If you uninstall the app without asking for deletion, the synced copy stays so you do not lose your history when you change devices.
6. Your rights
You may request access, correction, a copy (portability), or deletion of your data, and withdraw consent. These rights are guaranteed by Brazil's LGPD(Law 13.709/2018) and equivalent laws elsewhere, including California's.
Email info@summitviewland.com. We respond within 15 days. To erase everything, just ask — we delete the account and the synced data, free of charge and without trying to talk you out of it. Uninstalling the app removes the local copy from your device.
7. Children
YolkHatch is not directed to anyone under 18 and we do not knowingly collect children's data. If you know of such an account, tell us at the address above and we will remove it.
8. This is not medical advice
YolkHatch is a tracking and engagement tool. It is not a medical device, it does not diagnose, and it does not prescribe. Default goals are a generic starting point — decisions about your diet, medication, or post-operative care belong with the healthcare professional who treats you.
9. Changes to this policy
If anything material changes, we will tell you inside the app before it takes effect. The date at the top of this page reflects the last revision.
