Consumer Health Data Privacy Policy
Effective: November 6, 2026
This policy explains how MINDSETUP ("we"), the operator of the Jaksimsamil intermittent fasting app and website (the "Service"), handles consumer health data. It is provided for users in the United States, including under the Washington My Health My Data Act and Nevada SB 370. Our full privacy policy (in Korean) is at privacy.html; if the two differ for U.S. users, this page controls for consumer health data.
1. Consumer health data we collect
- Body information you enter: sex, birth year, height, weight and weight history, goal weight, and optionally waist size and body fat.
- Health conditions you choose in the setup survey (for example: taking diabetes medication, pregnancy or breastfeeding, being underweight, history of eating difficulties, high blood pressure, gout, kidney disease, reflux, joint pain).
- Fasting plans and fasting times, meals and foods you log with estimated calories and protein, and exercise you log.
- Information derived from the above, such as daily calorie and protein targets and progress summaries.
2. How we collect it (sources)
Directly from you, when you enter it in the Service. By default it is stored only on your device. If you sign in, it is saved to your account on our server in the Republic of Korea so you can restore and sync it. The Service also sends anonymous usage events (for example, that a fast started or ended and how many hours it lasted) tied to a random device number, not to your name or account; these events never include weight, meals, or health conditions.
3. Why we collect and use it
- To provide the Service: build your fasting plan, adjust or pause fasting for health conditions where fasting may not be appropriate, calculate calories and protein, and show your progress.
- To save, restore, and sync your records when you sign in.
- To improve the Service using anonymous, aggregated statistics.
We do not use consumer health data for advertising, and we do not sell it.
4. Who we share it with
- Friends you choose ("fasting buddies"): only your display name, current fasting time, whether you met today's mission, level, and streak. Never weight, meals, or health conditions.
- Service providers that process data on our behalf: Cloudflare, Inc. (secure transmission between your device and our server) and Google LLC (storage of encrypted daily backups that only we can decrypt).
- Apple processes App Store subscriptions and Sign in with Apple. We receive subscription status from Apple but do not send health data to Apple.
- Authorities, only when required by law.
5. Consent
When you create an account, we ask for your separate consent to save health information to your account. You can withdraw consent at any time by deleting your account.
6. Your rights
- Access: see your records in the app, or ask us for a copy and a list of the third parties and service providers that received your data.
- Delete: delete your account in the app (Account › Delete account), or email us. This deletes your records, photos, and messages on our server; encrypted backups are removed within 30 days. Records kept only on your device are removed when you delete the app or its data.
- Withdraw consent: delete your account or email us.
- Appeal: if we decline your request, reply to our decision by email to appeal. If your appeal is denied, you may contact the Washington State Attorney General (atg.wa.gov) or your state's attorney general.
We respond within 45 days. We do not discriminate against you for exercising these rights.
