CapsulaCapsula — Terms of Service & End User License Agreement
Effective Date: June 27, 2026 Last Updated: June 29, 2026
These Terms of Service ("Terms") form a binding agreement between you ("you" or "User") and Capsula ("we", "us", or "our"), governing your access to and use of the Capsula mobile application and related services (collectively, the "App" or "Service").
The App is a personal supplement-tracking and personal correlation-analysis tool. The App provides informational content only and does not sell supplements or any other product.
Please read these Terms carefully, together with our Privacy Policy (https://usecapsula.app/legal/privacy.html), which is incorporated into these Terms by reference.
1. Acceptance of Terms & Eligibility
1.1 Acceptance. You accept these Terms by taking an affirmative action indicating acceptance — for example, by checking the "I agree" box or tapping the equivalent control when you create an account or first use the App — and/or by downloading, accessing, or using the App, including by continuing to use the App after these Terms are updated. Where you accept through an affirmative action, we retain a record of your acceptance, including the date and the version of the Terms accepted. If you do not agree, do not download, access, or use the App.
1.2 Eligibility (16+). You must be at least 16 years of age to use the App. By using the App, you represent and warrant that you are at least 16 years old and that you have the legal capacity to enter into these Terms. If you are using the App on behalf of a minor for whom you are a parent or legal guardian, you accept these Terms on their behalf and are responsible for their use of the App. We do not knowingly collect data from children under the applicable age of digital consent; see the Privacy Policy for details.
1.3 Informational use only. You acknowledge that the App is intended for general wellness and informational purposes and is not a substitute for professional medical advice. See Section 3 (Medical & Supplement Disclaimer), which is a material part of these Terms.
2. Apple Standard EULA Relationship
2.1 Standard EULA applies. The App is licensed, not sold, to you. Your license to use the App is subject to Apple's Licensed Application End User License Agreement ("Standard EULA"), available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. These Terms supplement the Standard EULA and impose additional terms. In the event of a direct conflict between these Terms and the Standard EULA, the Standard EULA governs solely with respect to the subject matter it addresses, and these Terms otherwise apply.
2.2 Scope of license. Subject to your compliance with these Terms and the Standard EULA, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App on any Apple-branded device that you own or control, as permitted by the Usage Rules set forth in the Apple Media Services Terms and Conditions.
2.3 Maintenance and support. Capsula — not Apple — is solely responsible for providing
any maintenance and support services for the App, to the extent such services are required under
applicable law or are offered by Capsula. Apple has no obligation to furnish any maintenance
or support services with respect to the App. You may contact Capsula for support at
hello@usecapsula.app.
2.4 Warranty. To the maximum extent permitted by applicable law, Apple provides no warranty whatsoever with respect to the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) you paid for the App. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the App. As between Apple and Capsula, any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to a warranty are the sole responsibility of Capsula, subject to Section 8 below.
2.5 Product claims. Capsula, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including but not limited to: (a) product liability claims; (b) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (c) claims arising under consumer protection, privacy, or similar legislation.
2.6 Intellectual property 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, Capsula, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such infringement claim, subject to Section 8.
2.7 Legal compliance. You represent and warrant that (a) 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 (b) you are not listed on any U.S. Government list of prohibited or restricted parties.
2.8 Developer contact. Questions, complaints, or claims with respect to the App should be
directed to Capsula at hello@usecapsula.app.
2.9 Apple as third-party beneficiary. You acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that, 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.
3. Medical & Supplement Disclaimer
PLEASE READ THIS SECTION CAREFULLY. IT IS A MATERIAL PART OF THESE TERMS.
3.1 Not a medical device; not medical advice. Capsula is a wellness and informational tool. The App is not a medical device, and it does not provide medical advice, diagnosis, treatment, or any professional healthcare service. No content in the App — including supplement information, ingredient descriptions, timing or interaction information, correlation results, AI-generated insights and summaries, the AI Coach / Nutrition Advisor, or any other output — is intended to diagnose, treat, cure, mitigate, or prevent any disease or health condition.
3.2 Informational purpose only. All supplement information, all AI-generated insights and summaries, and all outputs of the AI Coach / Nutrition Advisor are provided for general informational and educational purposes only and are not a substitute for the advice, diagnosis, or treatment of a qualified physician, pharmacist, or other licensed healthcare professional. Never disregard professional medical advice, or delay seeking it, because of something you read or received in the App.
3.3 Correlation is not causation. The App's correlation analysis is a statistical observation of patterns in the data you log. It is not, and should not be interpreted as, evidence of causation, clinical proof, or a medical finding. Correlation results can be affected by many factors outside the App's awareness, may be based on limited data, and may be inaccurate or incomplete. You should not make health decisions based solely on correlation results.
3.4 Consult a professional; emergencies. Consult your physician or a qualified healthcare professional before starting, stopping, or changing any supplement, medication, diet, or health regimen, and especially if you are pregnant, nursing, have a medical condition, or are taking prescription medication. If you think you may have a medical emergency, call 911 (or your local emergency number) or seek emergency medical care immediately. Do not rely on the App in any situation requiring urgent or professional medical attention.
3.5 FDA notice (United States). Dietary supplements are regulated as a category of food, not as drugs. Statements regarding dietary supplements presented in the App have not been evaluated by the U.S. Food and Drug Administration (FDA). Supplements are not intended to diagnose, treat, cure, or prevent any disease. Individual results vary, and no specific outcome is promised or guaranteed.
3.6 Limited interaction information; no dosage or safety checking. Any interaction information in the App is limited to certain supplement-to-supplement combinations identified by a limited, rules-based dataset; it is not exhaustive and may be incomplete or inaccurate. The App does not check for interactions between supplements and your medications, and does not check for contraindications, allergies, overdose, toxicity, or tolerable upper intake levels. Many vitamins and minerals (for example iron, vitamin A, and vitamin D) can be harmful in excessive amounts. Any dosage or timing information shown in the App is general and is not personalized to you. You are solely responsible for verifying safe use with a qualified healthcare professional.
3.7 Your responsibility. You are solely responsible for your own health decisions and for how you use any information provided by the App. To the maximum extent permitted by law, Capsula disclaims all liability arising from your reliance on any information or output in the App. See Sections 8 and 9.
3.8 Assumption of risk; acknowledgment. You acknowledge that decisions about dietary supplements — including which to take, dosage, timing, and combinations — carry inherent risks, and that supplements can cause harm, including if taken in excessive amounts or together with medications or with certain medical conditions. To the maximum extent permitted by law, you knowingly and voluntarily assume full responsibility for, and all risks associated with, your use of the App and any action you take based on any information, correlation result, or AI output in the App, and you release Capsula from any claims arising from those risks. You represent that you are able to evaluate such information and will exercise your own independent judgment and, where appropriate, the judgment of a qualified healthcare professional. This acknowledgment is a material inducement for Capsula to provide the App.
4. Subscriptions — Capsula Pro
4.1 Free and paid tiers. The App offers a free tier and an optional paid subscription, "Capsula Pro", which unlocks additional features. The specific features included in each tier may change over time at our discretion.
4.2 Billing through the App Store. Capsula Pro is offered as an auto-renewing subscription sold through Apple's in-app purchase system. All payments are processed by Apple and are charged to your Apple ID account at confirmation of purchase. Capsula does not collect or store your payment card details. Available plans (e.g., monthly and annual) and their prices are displayed in the App at the time of purchase; current pricing is governed by what is shown at checkout.
4.3 Auto-renewal. Your subscription automatically renews for the same period unless you cancel it at least 24 hours before the end of the current period. Your Apple ID account will be charged for renewal within 24 hours prior to the end of the current period, at the then-current price for the applicable plan.
4.4 Cancellation. You can manage or cancel your subscription at any time through your Apple ID account settings (Settings → your name → Subscriptions on your device, or via the App Store). Cancellation takes effect at the end of the current billing period; you will retain access to Capsula Pro features until that time. Deleting the App does not, by itself, cancel your subscription.
4.5 Free trial (if offered). If a free trial is offered, the terms (including duration and eligibility) will be disclosed at the point of purchase. Unless you cancel at least 24 hours before the end of the free trial, the subscription will automatically convert to a paid, auto-renewing subscription and your Apple ID account will be charged. Any unused portion of a free trial is forfeited upon purchase of a subscription, where applicable.
4.6 Price changes. We may change subscription prices. Where required, price changes affecting your existing subscription will be communicated to you in advance through Apple and/or the App, in accordance with Apple's policies, and (where required) will require your consent to continue. If you do not agree to a price change, you may cancel before it takes effect.
4.7 Refunds. All purchases are processed by Apple and are subject to Apple's refund policies. Capsula generally cannot grant refunds for purchases made through the App Store; refund requests must be directed to Apple. Except where required by applicable law, payments are non-refundable and there are no refunds or credits for partially used periods.
5. User Content & Acceptable Use
5.1 Your content. The App allows you to enter and store data, such as supplements, doses, wellbeing scores, and notes ("User Content"). You retain ownership of your User Content. You grant Capsula a limited, worldwide, royalty-free license to host, process, and use your User Content solely to operate and provide the Service to you (for example, to compute correlations or generate AI Coach / Nutrition Advisor responses), as further described in the Privacy Policy.
5.2 Your responsibility for content. You are solely responsible for your User Content and for the accuracy of the data you enter. Inaccurate data may produce inaccurate outputs.
5.3 Acceptable use. You agree not to, and not to permit others to: - (a) use the App for any unlawful, harmful, or fraudulent purpose; - (b) reverse engineer, decompile, disassemble, or attempt to derive the source code of the App, except to the extent such restriction is prohibited by applicable law; - (c) copy, modify, distribute, sell, sublicense, rent, or lease the App or any part of it; - (d) use any robot, scraper, crawler, or other automated means to access the Service, or circumvent, disable, or interfere with any rate limits, security, or access controls; - (e) attempt to gain unauthorized access to any account, system, or network associated with the App; - (f) introduce any malware or interfere with the integrity or performance of the Service; or - (g) misuse the AI Coach / Nutrition Advisor, including attempting to extract underlying prompts, models, or proprietary instructions, or using it to generate harmful, illegal, or abusive content.
5.4 Suspension. We may suspend or terminate your access to the Service if we reasonably believe you have violated these Terms. See Section 9.
6. Intellectual Property
6.1 Capsula ownership. The App and all content provided by Capsula — including software, text, supplement information, designs, graphics, the "Capsula" name, logo, and other trademarks, and the AI Coach / Nutrition Advisor's prompts, models, and instructions — are owned by Capsula or its licensors and are protected by intellectual property laws. All rights not expressly granted to you are reserved.
6.2 Limited license to you. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial purposes. This license does not include any right to use Capsula's trademarks or branding without our prior written consent.
6.3 Feedback. If you provide suggestions or feedback about the App, you grant Capsula a perpetual, irrevocable, royalty-free license to use that feedback for any purpose without obligation to you.
7. AI Features
7.1 Nature of AI output. The AI Coach / Nutrition Advisor and the AI-generated insights and summaries in the app produce output using automated systems and large language models. AI-generated output may be inaccurate, incomplete, out of date, or otherwise unreliable, and may not reflect your individual circumstances. Output is informational only and is subject to Section 3 (Medical & Supplement Disclaimer).
7.2 Use your own judgment. You should independently evaluate any AI-generated output and, where appropriate, consult a qualified healthcare professional before acting on it. You are responsible for your decisions and for verifying any information before relying on it.
7.3 No professional relationship. Use of the AI features does not create a doctor-patient, pharmacist-patient, or any other professional relationship between you and Capsula.
7.4 Usage limits. AI features may be subject to usage quotas, rate limits, or availability restrictions, which may differ between the free and Capsula Pro tiers and which may change over time.
7.5 Emergencies. Never use the AI Coach / Nutrition Advisor for medical emergencies. If you think you may have a medical emergency, or a serious or worsening condition, stop using the App and call 911 (or your local emergency number) or seek emergency care immediately.
7.6 Known limitations of AI output. The AI Coach / Nutrition Advisor may generate statements that sound plausible but are incorrect, incomplete, out of date, or fabricated ("hallucinated"). It does not have access to your full medical history, diagnoses, laboratory results, or allergies, or to the medications you take, and therefore cannot and does not screen for drug–supplement interactions, contraindications, allergic reactions, cumulative dosage, or safe upper intake levels. You must not rely on it to identify, confirm, or rule out any health risk.
7.7 No reliance for dosing or medication decisions. Do not use the AI Coach or any other App content to determine dosing, to combine supplements, or to start, stop, or change any medication or treatment. Such decisions must be made only with a qualified healthcare professional who knows your individual circumstances.
8. Disclaimer of Warranties; Limitation of Liability
8.1 "AS IS". TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL CONTENT AND SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT. CAPSULA DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT ANY INFORMATION OR OUTPUT (INCLUDING CORRELATION RESULTS OR AI OUTPUT) WILL BE ACCURATE OR RELIABLE.
8.2 Limitation of liability. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL CAPSULA OR ITS OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR HEALTH OUTCOMES, ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR USE OF (OR INABILITY TO USE) THE APP, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, EVEN IF CAPSULA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
8.3 Cap on liability. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CAPSULA'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU PAID TO CAPSULA (THROUGH APPLE) FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD 100.
8.4 Exceptions. Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. In such jurisdictions, the above exclusions and limitations apply only to the extent permitted by law, and nothing in these Terms limits liability that cannot be limited under applicable law.
9. Indemnification
To the maximum extent permitted by applicable law, you agree to indemnify, defend, and hold harmless Capsula and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your misuse of the App; (b) your violation of these Terms; (c) your violation of any law or the rights of any third party; or (d) your User Content. This Section does not apply to the extent a claim arises from Capsula's own gross negligence or willful misconduct, or where such indemnification is prohibited by applicable law.
10. Termination; Account Deletion; Privacy
10.1 Termination by you. You may stop using the App at any time. You may delete your account and associated data through the in-app account-deletion feature; subscription cancellation is handled separately through Apple (see Section 4.4).
10.2 Termination by us. We may suspend or terminate your access to the Service, in whole or in part, with or without notice, if we reasonably believe you have violated these Terms or if required by law.
10.3 Effect of termination. Upon termination, your license to use the App ends. Sections that by their nature should survive termination — including Sections 3, 6, 7, 8, 9, and 11 — will survive.
10.4 Privacy. Your use of the App is also governed by our Privacy Policy (https://usecapsula.app/legal/privacy.html), which describes how we collect, use, and protect your data and is incorporated into these Terms by reference.
11. Governing Law; Dispute Resolution; Changes; Contact
11.1 Governing law. These Terms are governed by and construed in accordance with the laws of Türkiye, without regard to its conflict-of-laws principles, except where pre-empted by applicable mandatory consumer-protection law in your country of residence.

11.3 Arbitration / class-action waiver. Not included at this time.
11.4 Changes to these Terms. We may update these Terms from time to time. If we make material changes, we will provide reasonable notice (for example, in-app or by updating the "Last Updated" date). Your continued use of the App after the changes take effect constitutes your acceptance of the revised Terms. If you do not agree, you must stop using the App.
11.5 Severability & waiver. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect. Our failure to enforce any provision is not a waiver of that provision.
11.6 Entire agreement. These Terms, together with the Privacy Policy and Apple's Standard EULA, constitute the entire agreement between you and Capsula regarding the App and supersede any prior agreements on that subject.
