Klense Terms of Use

Effective date: July 11, 2026 Last updated: August 3, 2026

These Terms of Use (the "Terms") are a legal agreement between you and Cole Thapanawat, sole proprietor ("Klense," "we," "us") governing your use of the Klense iOS application and related services (the "App"). By creating an account, subscribing, or using the App, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App.

1. What Klense is — and is not

Klense is a personal hygiene system: it builds a personalized routine of hygiene tasks, tracks your completion of them, computes an on-device hygiene score, and offers an AI assistant that can suggest adjustments to your routine (a Klense Premium feature — Section 5).

Klense is not a medical service. Its content and the AI assistant's guidance are educational and general-wellness in nature. They are not medical advice, diagnosis, or treatment, and are not a substitute for the advice of a physician, dermatologist, dentist, or other qualified professional. Never disregard or delay professional advice because of something in the App. If you have a medical condition or concern — including persistent skin, scalp, or dental issues — consult a professional.

2. Eligibility

You must be at least 13 years old to use the App. If you are under the age of majority where you live, you may use the App only with the involvement and consent of a parent or legal guardian who agrees to these Terms on your behalf. By using the App you represent that you meet these requirements.

3. Your account

You need an account (Sign in with Apple or Google sign-in) to use the App. You are responsible for the accuracy of your account information and for all activity under your account, and you agree to keep the Apple or Google account you sign in with secure. You can delete your account at any time in Settings → Delete Account; deletion is immediate and irreversible and removes your data from our servers, but it does not cancel your subscription — manage that separately with Apple (Section 5.3).

4. License

Subject to these Terms, we grant you a personal, limited, revocable, non-transferable license to use the App on any Apple-branded device that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions (except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing, where applicable). This license is for your personal, non-commercial use. We reserve all rights not expressly granted.

You may not: copy, modify, distribute, sell, rent, or sublicense the App; reverse engineer or attempt to extract its source code except as permitted by law; circumvent usage limits, free-tier feature limits, subscription entitlement, or security measures; use the App to build a competing product; or use automated systems to access the App or its AI assistant.

5. Subscription — Klense Premium

Klense is free to use. The free tier is the complete hygiene product: your personalized routine and schedule, the full curated task library, every "How To" guide and "Why This Matters" rationale, task timers and completion tracking, your hygiene score, all notification types, up to 3 custom tasks, profile editing, data export, and sync across your devices. No payment is required and the free tier is not time-limited — you may use the App indefinitely without subscribing.

Klense Premium is an optional auto-renewing subscription that unlocks the additional features listed in Section 5.1.

5.1 Plans and pricing

Prices are in U.S. dollars and may vary by country; the price shown in the App at the time of purchase is the price you will be charged. There is currently no free trial or introductory offer.

Klense Premium currently unlocks:

• the AI assistant, subject to the fair-use limits in Section 6.3;
• Dashboard insights — the activity heatmap and the analytics features we add alongside it; and
• unlimited custom tasks, lifting the free tier's 3-task limit.

We may add features to Klense Premium over time, and we may change what each tier includes; material changes are handled under Section 10. If we change the price of an existing subscription, Apple will seek your consent before any increase takes effect, in accordance with Apple's rules — otherwise your subscription will not renew at the new price.

5.2 Billing and automatic renewal

Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically at the same price and period unless you cancel at least 24 hours before the end of the current period; the renewal charge is made to your Apple Account within 24 hours before the current period ends.

5.3 Cancelling

You can cancel anytime in your device's Settings → [your name] → Subscriptions (or via the manage-subscription screen inside the App, which opens Apple's subscription manager). Cancelling stops future charges; you keep Premium access until the end of the period you already paid for, after which your account returns to the free tier (Section 5.5). Uninstalling the App does not cancel your subscription.

5.4 Refunds

Purchases are processed by Apple, and refunds are governed by Apple's policies. To request a refund, use reportaproblem.apple.com or contact Apple Support; except as described in Section 14 (Warranty) or where required by law, we cannot issue refunds for App Store purchases ourselves.

5.5 Plan changes, lapse, and restore

The App offers an upgrade option from monthly to annual, which opens Apple's subscription manager; the plan change itself is executed by Apple's subscription system. If you reinstall or switch devices, use Restore Purchase to re-activate your entitlement.

If your subscription ends — because you cancelled, it lapsed, or a renewal failed — you are not locked out of the App. Your account simply returns to the free tier, and your data (profile, routine, completion history, and custom tasks) is preserved. Custom tasks you already created stay on your schedule and remain editable even if you hold more than the free-tier limit; the limit applies only to creating new ones. Premium features become available again as soon as you resubscribe or restore a purchase.

6. The AI assistant

The AI assistant is a Klense Premium feature and requires an active subscription. Before each request is processed, your entitlement is verified against the Apple-signed record of your subscription; requests without an active subscription are declined.

6.1 It is an AI

The Klense assistant is an automated AI system (powered by Google Gemini), not a human. It may make mistakes, and its output may be inaccurate or incomplete. Use your own judgment before acting on its suggestions; every proposed routine change requires your explicit approval in the App before it takes effect. Section 1's medical disclaimer applies fully to AI output.

6.2 Data sharing consent

Before your first message is sent, the App discloses what will be shared with Google (your message, your hygiene profile, and your routine) and requires your explicit consent. Details are in our Privacy Policy. Your chat history stays on your device.

6.3 Fair use and moderation

AI usage is subject to fair-use limits (currently 3 conversations per day, plus overall daily request ceilings that prevent abuse; limits may change). You agree not to use the assistant to generate or solicit content that is unlawful, harmful, or outside the App's hygiene scope, or to attempt to extract its underlying prompts or bypass its safety constraints. You can report an objectionable AI response by touch-and-holding it and choosing Report. We may throttle or suspend AI access to prevent abuse. The assistant also depends on a third-party AI provider and on overall capacity limits we set to keep the feature sustainable, so it may be temporarily unavailable; the rest of the App is unaffected.

7. Your content

You retain ownership of content you create in the App (custom task names, instructions, notes, and messages to the assistant). You grant us a limited, worldwide, royalty-free license to host, store, process, and transmit that content solely to operate and improve the App as described in the Privacy Policy — including transmitting relevant content to our AI provider to generate responses you request. You are responsible for your content and must not submit content that is unlawful or infringes anyone's rights. We do not use your content to train AI models.

8. Intellectual property

The App — including its software, design, curated hygiene content, research knowledge base, trademarks, and branding — is owned by us or our licensors and is protected by intellectual-property laws. Except for the license in Section 4 and your own content in Section 7, nothing in these Terms transfers any rights to you.

9. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate your access if you materially breach these Terms (including abuse of the AI assistant or attempts to circumvent subscription entitlement), if required by law, or if we discontinue the App; where practicable we will give you reasonable notice and, if we discontinue the App while you have active paid time, we will work with Apple to make appropriate refunds available. Sections 1, 7 (as to prior processing), 8, 12–19, and 20–23 survive termination.

10. Changes to the App and these Terms

We may update the App, its features, and fair-use limits over time, and may modify these Terms. For material changes we will notify you in the App or by email before they take effect; continued use after the effective date constitutes acceptance. If you do not agree, stop using the App and cancel your subscription.

11. Third-party services

The App relies on third-party services (Apple, Supabase, Google, Superwall, Mixpanel, Sentry) described in the Privacy Policy. Their availability is outside our control, and their terms govern your relationship with them where applicable.

Sections 12–19 implement clauses that Apple requires in any custom EULA for apps distributed through the App Store.

12. Acknowledgement (Apple is not a party)

These Terms are concluded between you and us only — not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the App and its content. These Terms do not provide usage rules that conflict with the Apple Media Services Terms and Conditions, which you acknowledge you have had the opportunity to review.

13. Maintenance and support

We are solely responsible for providing any maintenance and support for the App, as specified in these Terms or required by law. Apple has no obligation whatsoever to furnish any maintenance and support services for the App. For support, contact us at the address in Section 22.

14. Warranty

We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are our sole responsibility.

Subject to the foregoing and to Section 20, the App is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that AI output will be accurate. Some jurisdictions do not allow certain warranty disclaimers, so parts of this section may not apply to you.

15. Product claims

We, not Apple, are responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of it, including but not limited to: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation, including in connection with the App's use of HealthKit or HomeKit frameworks (which Klense does not use).

16. Intellectual property rights (third-party claims)

In the event of any third-party claim that the App, or your possession and use of the App, infringes that third party's intellectual property rights, we — not Apple — are solely responsible for the investigation, defense, settlement, and discharge of any such claim.

17. Legal compliance

You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

18. Third-party terms of agreement

You must comply with any applicable third-party terms of agreement when using the App (for example, your wireless carrier's data agreement and the third-party service terms referenced in Section 11).

19. Third-party beneficiary

Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary hereof.

20. Limitation of liability

To the maximum extent permitted by law: (a) we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, data, or goodwill, arising out of or relating to the App, even if advised of the possibility; and (b) our total aggregate liability for all claims relating to the App will not exceed the greater of US $50 or the amount you paid us for the App in the twelve (12) months before the claim arose. Nothing in these Terms limits liability that cannot be limited by law, including for gross negligence, willful misconduct, or death or personal injury caused by negligence where such limits are not permitted. You use hygiene guidance at your own discretion; you are responsible for patch-testing products and discontinuing anything that causes irritation.

21. Governing law and disputes

These Terms are governed by the laws of the Commonwealth of Virginia, USA, without regard to conflict-of-law rules, and the state and federal courts located in or serving Loudoun County, Virginia will have exclusive jurisdiction over disputes, except that either party may seek relief in small-claims court and you may have mandatory rights under the consumer-protection laws of your country of residence.

Direct any questions, complaints, or claims with respect to the App to this address.

23. General

These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the App. If any provision is found unenforceable, the rest remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets.
