By downloading, installing, registering for, or using any part of the Service, you enter into a legally binding contract with Kallo effective as of the date of your first access.
These Terms incorporate by reference our Privacy Policy, Community Guidelines, and any other policies we publish within the Service. In any conflict, these Terms shall prevail unless a supplementary policy expressly governs a specific subject matter.
These Terms are drafted in English, which is the controlling language. Any translation is for convenience only; in any inconsistency, the English version governs.
The Service is available exclusively to individuals who are 18 years of age or older. By registering, you represent and warrant that you are at least 18. We reserve the right to immediately terminate any account where we have reasonable grounds to believe the holder is under 18, without prior notice or liability.
You agree to provide truthful, current, and complete registration information, including your real date of birth. Providing false information to circumvent the age restriction is a material breach of these Terms and grounds for immediate permanent account termination.
Each individual may maintain only one active Kallo account. Creating duplicate accounts to evade bans, suspensions, or enforcement actions is prohibited and may result in permanent termination of all associated accounts.
You may register via Apple Sign-In or Google. By doing so, you authorize Kallo to receive limited profile information from those providers as permitted by your consent settings, subject to their respective terms and privacy policies.
The Service may not be available or fully functional in all jurisdictions. You are responsible for ensuring your use complies with the laws of your country of residence.
Because Kallo connects real people for training that may occur in person, you must complete identity verification — submitting a photo and a live comparison photo for facial matching — before you may publicly share fitness results or use the workout partner-matching feature. See our Privacy Policy, Section 3, for details on how this data is collected, used, and retained.
You must complete verification using your own likeness. Submitting another person's photo, using manipulated images, or otherwise attempting to circumvent verification is strictly prohibited and grounds for immediate account termination.
You may use Kallo's core plan-building and private tracking features without completing verification. Verification is required only for public fitness-results sharing and partner matching.
We may require re-verification periodically or upon detecting signals suggesting your account may be compromised or associated with suspicious activity. Failure to complete requested re-verification may result in suspension of results-sharing and matching access.
You are solely responsible for maintaining the confidentiality of your account credentials. Do not share your password with any third party. Kallo will never request your password through any communication channel.
Notify us promptly at service@kallo.app if you suspect unauthorized use of your account. To the fullest extent permitted by law, Kallo is not liable for losses arising from unauthorized use prior to your notification.
You are fully responsible for all activity occurring through your account, including all plans built, results shared, matches initiated, and purchases made, whether or not personally initiated by you.
Kallo is a global fitness platform providing:
- A workout plan builder for creating, customizing, and following training programs
- Progress tracking for logged workouts, personal records, and body metrics
- Fitness results sharing to publish achievements and progress to the community, subject to identity verification
- Workout partner matching to find other verified users pursuing the same or a similar training plan
- In-app messaging with matched partners
- Community features including following, reactions, and comments
- In-app purchases for optional premium features
We strive for continuous availability but do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, infrastructure issues, or events beyond our reasonable control.
Kallo is continuously developed. We may add, modify, or discontinue features at any time. We will provide reasonable advance notice of material changes affecting your use of the Service.
Workout plans you build or customize are your original creative and organizational work. Kallo does not claim ownership of your individual plans, subject to the license granted in Section 10.2 for any plans you choose to publish publicly as templates.
You are responsible for the accuracy of the workout data, weights, and results you log. Kallo does not independently verify logged training data and is not responsible for errors in your personal records.
Kallo provides tools to build and follow workout plans. We do not guarantee that following any plan — whether created by you, another user, or featured by Kallo — will produce any particular fitness outcome, weight change, or performance result. Individual results vary based on many factors outside our control.
You must complete identity verification (Section 3) before your account may publish fitness results, progress photos, or achievements publicly.
If you promote supplements, products, or paid services in connection with your shared results, you must clearly and conspicuously disclose any material connection (such as sponsorship, affiliate relationship, or free product) in accordance with applicable advertising disclosure laws.
Progress photos must comply with our Community Guidelines, including prohibitions on sexually explicit content. Photos intended primarily to be sexually suggestive rather than to document fitness progress are not permitted, regardless of clothing worn during exercise.
Kallo's partner-matching feature helps you find other verified users pursuing the same or a similar workout plan for shared accountability and, potentially, in-person training.
If you choose to meet a training partner in person, we strongly recommend that you:
- Meet for the first time at a public gym, studio, or fitness location — never a private residence
- Tell a friend or family member where you're going, who you're meeting, and when you expect to return
- Arrange your own transportation to and from the meeting
- Trust your instincts — leave immediately if you feel unsafe
- Avoid sharing sensitive personal or financial information with matched partners
You acknowledge and agree that meeting any person found through Kallo, whether communicating in-app or meeting in person, is undertaken at your own risk. To the fullest extent permitted by applicable law, Kallo disclaims liability for the conduct, whether online or offline, of any user, and for any injury, loss, or damage resulting from interactions with matched partners. See Sections 20–21 for full disclaimers and liability limitations.
If a matched partner behaves inappropriately, makes you feel unsafe, or violates our Community Guidelines, report them immediately using the in-app Report function. We take matching-related safety reports seriously and will investigate promptly.
Before beginning any new exercise program, including any workout plan built or found on Kallo, you should consult with a qualified healthcare provider, particularly if you have any pre-existing medical condition, injury, or health concern.
Physical exercise carries inherent risk of injury. By using Kallo's workout plans and features, you voluntarily assume all risks associated with physical exercise, including risks arising from following plans created by other users or from training with a matched partner.
Workout plans created and shared by other users are not reviewed or endorsed by fitness professionals employed by Kallo unless expressly labeled as such. Exercise judgment when following plans created by other community members.
You are solely responsible for all content you publish or submit through the Service, including fitness results, progress photos, plan templates, comments, and messages. By submitting content, you represent and warrant that you own or have all necessary rights to it and that it complies with these Terms and all applicable laws.
By publishing UGC publicly on Kallo, you grant us a non-exclusive, worldwide, royalty-free, sublicensable license to host, store, reproduce, display, and distribute your content within the Service and in connection with promoting Kallo, subject to your visibility settings. You retain ownership of all original content you create.
Publication of UGC on Kallo does not constitute our endorsement or verification of that content, including the accuracy of any fitness claims made.
You may delete your published content at any time. Deleted content is removed from public view within 48 hours, from production servers within 30 days, and from backup archives within 90 days.
Kallo is built for people supporting each other's fitness journeys. We ask all members to engage with encouragement, honesty, and respect toward fellow athletes of all levels and body types.
You may not use Kallo to harass, bully, threaten, or target any individual, including in matching conversations, comments, or community posts. Violations result in immediate enforcement action and may be reported to law enforcement.
Content or comments that shame, mock, or demean another user's body, fitness level, or physical appearance are strictly prohibited, including in comments on shared fitness results.
Content promoting hatred or discrimination against individuals or groups based on race, ethnicity, national origin, religion, gender, sexual orientation, disability, body type, or any other protected characteristic is strictly prohibited.
Content promoting extreme, unsafe, or disordered approaches to exercise, eating, or supplementation is prohibited. This includes content glorifying overtraining, dangerous rapid weight loss methods, or misuse of performance-enhancing substances.
You may not use Kallo's community or matching features to post spam, unsolicited commercial messages, or unauthorized coaching/product sales pitches. Coaches or trainers wishing to offer services must comply with our commercial-use policies.
All rights, title, and interest in the Service — including the Kallo name, logo, application design, interface, software, matching algorithm, and all proprietary technology — are owned by or licensed to Kallo and protected by applicable intellectual property laws.
You retain ownership of your original workout plans, fitness results, and other UGC, subject to the license grant in Section 10.2.
If you submit ideas, suggestions, or feedback about the Service, you agree that Kallo may use such feedback freely without obligation. You assign to Kallo all intellectual property rights in such feedback to the extent assignable under applicable law.

Kallo is exclusively for users 18 years of age or older. We implement date-of-birth verification at registration, and our identity verification process provides an additional safeguard for results-sharing and matching. Confirmed underage accounts are immediately and permanently terminated with all associated data deleted.
If you are a parent or guardian and believe a minor has created a Kallo account, contact us immediately at service@kallo.app. We will investigate and, where confirmed, permanently delete the account and all associated data without delay.
We deploy automated CSAM hash-matching on all uploaded media, AI-assisted content analysis on community posts, and dedicated human safety reviewers. Upon confirmed detection or credible report: all associated content is immediately and permanently removed; the responsible account is permanently terminated and all associated identifiers are blocked; a mandatory report is filed with the NCMEC CyberTipline or the legally required equivalent national authority; and we cooperate fully with all resulting law enforcement investigations. CSAE-related terminations carry no right of appeal.
To report: use the in-app Report function on any content or user profile, or email service@kallo.app immediately with subject "CSAE Report." These are our highest-priority safety matter, actioned without delay.
Subject to your full and continued compliance with these Terms, Kallo grants you a personal, non-exclusive, non-transferable, revocable, limited license to install and use the Kallo application on devices you own or control, solely for your personal, non-commercial use to access the Service as intended.

Where applicable law does not permit certain caps, Kallo's liability is limited to the maximum extent permitted.
