Terms of Service
These terms govern your use of Vivledia, operated by Celevo Co., Ltd. ("we", "us"). Please read the Medical Disclaimer in Section 3 — it is the most important part of this document.
1. Agreement to These Terms
By creating an account or using the app, you agree to these terms. If you do not agree, please do not use the app.
- You must be at least 14 years old to use the app.
- You are responsible for the accuracy of the information you enter and for keeping your account credentials secure.
- You may delete your account at any time in Profile → Delete account permanently. Deleting your account permanently erases your records.
We may update these terms. If a change is material, we will notify you in the app before it takes effect.
2. What the App Is
Vivledia is a personal wellness journal. You record habits — sleep, exercise, diet, body measurements, alcohol and tobacco use, and supplements — and the app shows you those records back, calculates a lifestyle score from them, and generates general informational content.
What the app is not
- It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease.
- It does not provide medical advice, and no doctor-patient relationship is created by using it.
- Its scores and insights are not a clinical assessment and have not been validated as predictors of any health outcome.
The lifestyle score is our own design, built from published general guidance (for example on sleep duration, physical activity, sodium, and alcohol). We describe its basis openly in the app. It is a self-tracking aid, not a measurement of your health.
3. Medical Disclaimer
Everything in this app is general information only. It is not a substitute for professional medical diagnosis, treatment, or prescription.
- Always consult a qualified healthcare professional before making decisions about your health, and before starting, stopping, or changing any supplement, medication, diet, or exercise program.
- Never disregard professional medical advice, or delay seeking it, because of something you read in this app.
- If you think you may have a medical emergency, contact your local emergency services immediately.
Supplement and nutrient information — including dosage ranges, upper limits, interactions, and cautions — is drawn from publicly available reference sources and is provided for general education. Individual needs vary, and reference values differ between countries. Do not use it to self-treat.
To the extent permitted by law, we are not responsible for decisions you make about your health based on information shown in the app.
4. AI-Generated Content
Some features use artificial intelligence — for example photo-based food and supplement label scanning, exercise scanning, research summaries, and coaching messages.
- AI output can be wrong, including confidently wrong. Estimated calories, nutrients, and label readings are approximations.
- We do not warrant the accuracy or completeness of AI-generated content.
- Always check AI output against the product label or an authoritative source before relying on it.
AI features are processed by a third-party model provider. What we send and how it is handled is described in our Privacy Policy.
5. Subscriptions and Billing
The app offers optional paid subscriptions. On iOS, all purchases, renewals, and refunds are handled by Apple through your App Store account — we never see or store your payment details.
- Subscriptions renew automatically until you cancel. The price and billing period are shown to you before purchase.
- You are charged through your App Store account at confirmation of purchase, and again at the start of each renewal period.
- To cancel, use your device settings (Settings → your name → Subscriptions) at least 24 hours before the current period ends. Deleting the app does not cancel a subscription.
- Refund requests are handled by Apple under its refund policy. We cannot issue App Store refunds directly.
Credits included with a subscription are for use within the app, have no cash value, and are not redeemable or transferable.
6. Acceptable Use
You agree not to:
- Use another person's account, or let another person use yours.
- Reverse engineer, decompile, scrape, or attempt to gain unauthorized access to the service.
- Interfere with the service, or use it in a way that places an unreasonable load on our systems.
- Resell or commercially exploit the service or its content without our written permission.
- Submit content that is unlawful, or that infringes another person's rights.
We may suspend or terminate an account that violates these terms. Where practical, we will tell you why.
7. Availability by Region
Some features are not offered everywhere, because the applicable rules differ by country and state.
Menstrual cycle tracking was removed on August 2, 2026 and is no longer offered. No cycle data is collected from or synchronized for any user.
Which features you see is determined by your App Store storefront. Availability may change as we expand.
8. Your Content and Our Content
Your records are yours. We do not claim ownership of the data you enter, and we do not sell it. We use it only to operate the service for you, as described in our Privacy Policy.
So that the service can work, you give us permission to host, back up, and process the data you enter — only as needed to provide the features described in these terms, and for no other purpose.
The app itself — its software, design, text, and reference content — belongs to Celevo Co., Ltd. or its licensors, and is protected by intellectual property laws. These terms do not transfer any of those rights to you.
9. Changes to the Service
We may change, suspend, or discontinue features. If we discontinue something you rely on, we will give reasonable notice in the app where we can. You can delete your data at any time, and you can request a copy of the information we hold about you as described in our Privacy Policy.
10. Disclaimers and Limitation of Liability
The service is provided "as is" and "as available." To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or that any content is accurate or complete.
To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits or data, arising from your use of the service. Our total liability for any claim relating to the service is limited to the amount you paid us in the twelve months before the claim arose.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. Where that is the case, the exclusions and limitations above apply to you only to the extent permitted, and nothing in these terms removes rights you have that cannot be waived.
11. Governing Law
These terms are governed by the laws of the Republic of Korea, where Celevo Co., Ltd. is established, without regard to conflict-of-laws rules.
If you are a consumer, this does not deprive you of the protection of mandatory consumer-protection laws of the country or state where you live, and does not prevent you from bringing a claim where those laws allow it.
12. General
- Severability. If any part of these terms is found unenforceable, that part applies to the fullest extent permitted, and the rest of these terms remains in full effect.
- Entire agreement. These terms, together with the Privacy Policy and, where it applies, the Consumer Health Data Privacy Policy, are the entire agreement between you and us about the service.
- No waiver. If we do not enforce a part of these terms, that is not a waiver of our right to enforce it later.
On the App Store, the standard Apple Licensed Application End User License Agreement also applies to your download of the app itself. If it conflicts with these terms for a topic these terms cover, these terms govern between you and us.
