KREV — TERMS OF USE
Last updated: June 1, 2026
These Terms of Use ("Terms") govern your use of the Krev app ("Krev", "the app", "we",
"us"). By downloading or using Krev, you agree to these Terms. If you do not agree, do
not use the app.
Krev is a workout-tracking app with an AI physique-scan feature. It is provided as a
fitness and informational tool only.
1. ELIGIBILITY
You must be at least 13 years old (or the minimum age required in your region) to use
Krev. By using the app you confirm that you meet this requirement.
2. THE APP AND THE AI SCAN
Krev lets you plan routines, log workouts, track measurements, and run an AI-based
physique scan from a photo. The AI scan produces ESTIMATES generated by a machine-
learning model from a single image. Results — including body fat, muscle development,
proportions, posture, and any scores or recommendations — are approximate, can be
affected by lighting, pose, clothing, and angle, and may be wrong. They are for general
guidance only and are NOT a medical assessment, diagnosis, or body-composition
measurement.
3. NOT MEDICAL OR PROFESSIONAL ADVICE
Krev does not provide medical, nutritional, or professional fitness advice, and is not a
substitute for a qualified professional. Exercise carries inherent risk. Consult a
physician before starting any training program, and stop and seek help if you feel pain,
dizziness, or distress. You are solely responsible for how you train and for any
decisions you make based on the app. You use Krev at your own risk.
4. KREV PRO SUBSCRIPTIONS
Some features (including the AI physique scan) require a paid subscription, "Krev Pro".
- Payment is charged to your Apple ID account at confirmation of purchase.
- Subscriptions renew automatically unless auto-renew is turned off at least 24 hours
before the end of the current period.
- Your account is charged for renewal within 24 hours before the end of the period.
- You can manage or cancel subscriptions in your Apple ID account settings after
purchase. Deleting the app does not cancel a subscription.
- Any unused portion of a free trial, where offered, is forfeited when you purchase a
subscription.
- Prices may change; we will seek your consent for increases as required by the App
Store rules.
Purchases are processed by Apple and are subject to the Apple Media Services Terms and
the standard Apple licensed-application end user license agreement (see Section 9).
5. YOUR CONTENT AND DATA
You retain ownership of the photos and data you put into Krev. Most of your data is
stored on your device; the AI scan sends your photo to our AI provider only to generate
your analysis. How data is handled is described in our Privacy Policy, which is part of
these Terms. You are responsible for the content you submit and confirm you have the
right to use any photo you scan.
6. ACCEPTABLE USE
You agree not to:
- misuse, attack, or attempt to reverse-engineer the app or its AI service;
- use the app to violate any law or another person's rights;
- upload images you do not have the right to use, or images of other people without
their consent;
- attempt to bypass subscription or abuse-prevention controls.
7. INTELLECTUAL PROPERTY
Krev, including its design, software, and branding, is owned by us and protected by law.
We grant you a personal, non-transferable, non-exclusive license to use the app under
these Terms and the EULA in Section 9. You may not copy, resell, or redistribute the app.
8. DISCLAIMERS AND LIMITATION OF LIABILITY
The app is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, to the
fullest extent permitted by law. We do not warrant that the app or AI results will be
accurate, uninterrupted, or error-free.
To the maximum extent permitted by law, we are not liable for any indirect, incidental,
or consequential damages, or for any injury, loss, or damage arising from your use of the
app, the AI estimates, or your training decisions. Some jurisdictions do not allow
certain limitations, so some of the above may not apply to you.
9. APPLE STANDARD EULA
Your license to use Krev is also subject to the Apple Licensed Application End User
License Agreement ("Standard EULA"), available at:
https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
If anything in these Terms conflicts with the Standard EULA regarding your license to use
the app on Apple devices, the Standard EULA governs that point. You also acknowledge:
- These Terms are between you and us, not Apple; Apple is not responsible for the app
or its content.
- Apple has no obligation to provide support or maintenance for the app.
- Apple is a third-party beneficiary of these Terms and may enforce them.
10. CHANGES AND TERMINATION
We may update these Terms as the app evolves; material changes are reflected by the
"Last updated" date. We may suspend or end access if you violate these Terms. You may
stop using Krev at any time by deleting the app.
