Terms of Service
Last updated: June 13, 2026
1. Agreement to Terms
These Terms of Service ("Terms") form a binding agreement between you and the provider of Loop ("Loop," "we," "us," or "our") regarding your use of Loop. The provider's details are set out in the Governing Law and Dispute Resolution section below.
By downloading, accessing, or using the Loop mobile application (the "App"), the website at tryloop.health (the "Site"), and any associated tools, calculators, or content (together, the "Service"), you agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you do not agree to these Terms, do not use the Service.
If you have questions before agreeing, contact us at hello@tryloop.health.
2. Eligibility
The Service is intended only for individuals who are 18 years of age or older. By using the Service, you represent and warrant that you are at least 18 years old and have the legal capacity to enter into a binding agreement. We do not knowingly provide the Service to, or collect information from, anyone under 18. If we learn that we have collected information from a person under 18, we will delete it.
3. What Loop Is — and What It Is Not
Loop is a personal tracking and organization tool for people who follow a self-administered injection routine (such as peptide, GLP-1, or TRT routines). It helps you organize your own routine: recording the compounds, doses, schedules, and cycles you enter yourself, sending reminders for the times you set, keeping a log of the doses you record, and performing basic arithmetic (such as reconstitution/syringe math) on the numbers you type in.
Loop is not a medical product, a medical device, a pharmacy, or a healthcare provider. In particular, the Service does not:
- provide medical advice, diagnosis, or treatment;
- recommend, prescribe, or suggest what substance to take, how much, when, where, or in what combination;
- recommend or guide injection-site selection or rotation (site labels in the App are records of where you logged a dose, not recommendations);
- source, sell, supply, distribute, or facilitate obtaining any peptide, medication, hormone, or other substance;
- make any claim about health outcomes or efficacy.
Everything the Service displays — including logs, schedules, streaks, charts, summaries, and calculator output — is based solely on values you enter, and is provided for your own record-keeping and organizational convenience only.
We may add, change, suspend, or remove any feature, tool, or part of the Service at any time, with or without notice. Nothing in the Service or in our marketing is a guarantee that any particular feature will continue to exist or behave in a particular way.
4. Medical Disclaimer
The Service is not a substitute for professional medical advice, diagnosis, or treatment. It is a tracking and calculation tool only. It does not practice medicine, provide medical recommendations, prescribe anything, or diagnose any condition.
- Calculators and tools (including the reconstitution/syringe calculator) perform mathematical operations on the values you enter. They do not know or account for your medical history, drug interactions, allergies, physiology, or any individual health factor. Always independently verify any calculation with a qualified healthcare professional before acting on it.
- Charts, streaks, summaries, histories, and any other output are simply a representation of the data you have entered. They are illustrative records, not medical findings, and may be incomplete or inaccurate.
- Content on the Site and in the App is for general informational and organizational purposes only and is not medical advice.
Always consult a qualified healthcare professional before taking, starting, stopping, adjusting, combining, or otherwise acting on any medication, supplement, peptide, hormone, or other substance — whether or not you track it in the Service.
By using the Service, you acknowledge and agree that:
- You are solely responsible for your own health, medical, and routine decisions, including any decision about what to take, when, how much, and in what combination.
- We are not responsible for any substance you choose to take, obtain, possess, or administer.
- You will independently verify all information, calculations, and values with a qualified healthcare professional before relying on or acting on them.
- You will not rely on the Service as a sole source of information for any health or medical decision.
- You use the Service entirely at your own risk.
- We are not liable for any adverse outcome, side effect, interaction, missed dose, incorrect dose, or other consequence resulting from your use of, or reliance on, the Service.
No Professional Relationship
Your use of the Service does not create any physician-patient, healthcare-provider-patient, pharmacist-patient, dietitian-client, trainer-client, advisor-client, fiduciary, or other professional relationship between you and Loop or any of our service providers.
Emergency Situations
The Service is not designed for medical emergencies. If you believe you are experiencing a medical emergency, contact your local emergency services immediately (in the EU, dial 112).
Assumption of Risk
You acknowledge that researching, tracking, possessing, administering, or using peptides, medications, hormones, supplements, or related substances may involve known and unknown risks, including but not limited to: side effects; adverse or allergic reactions; incorrect dosage or administration; contamination, impurity, mislabeling, counterfeit products, or unknown ingredients; improper storage or handling; drug interactions; contraindications; infection or injury; risks not yet identified in scientific literature; and, in serious cases, lasting injury. You assume full responsibility for all decisions, actions, and outcomes arising from or related to any substance you track or any information you obtain through the Service. Nothing in this section excludes liability that cannot be excluded under applicable mandatory law (see Section 17).
5. Feature-Specific Disclaimers
The following apply in addition to the general Medical Disclaimer above.
Reconstitution / Syringe Calculator
The calculator performs reconstitution and dosage arithmetic based solely on the values you enter. Its results are mathematical outputs only and do not constitute medical advice, dosing instructions, prescription guidance, treatment recommendations, or a recommendation to use any substance. The Service does not verify your inputs; results may be wrong if your inputs are inaccurate, incomplete, mistyped, or based on incorrect product information. By using the calculator, you acknowledge that: (a) it does not provide medical advice or recommend any dose, schedule, substance, or protocol; (b) you are responsible for independently verifying every calculation; (c) you will consult a qualified healthcare professional before making any dosing or administration decision; and (d) we are not liable for any injury, adverse event, overdose, underdose, miscalculation, or improper administration arising from your use of or reliance on the calculator.
Injection-Site Labels
The body map and any site indicators are visual organizational tools only. They record the location labels you choose for your own reference. They do not provide medical guidance on injection technique, site selection, rotation, frequency, depth, sterility, or suitability, and do not detect or prevent infection, injury, improper administration, or adverse reactions. Always follow the guidance of a qualified healthcare professional.
6. No Sourcing; Your Responsibility for Lawful Use
The Service does not sell, source, supply, distribute, or facilitate obtaining any peptide, medication, or other substance, and contains no functionality intended for that purpose. We take no position on, and accept no responsibility for, any substance you choose to track.
You are solely responsible for ensuring that your possession and use of any substance you track, and your use of the Service generally, comply with all laws and regulations applicable to you in your own jurisdiction. The legal status of peptides and similar compounds varies by country and may be regulated, restricted, investigational, or prohibited where you live. We do not represent that any substance you track is legal, safe, approved, or appropriate for you.
7. Your Responsibilities
You agree to:
- provide accurate information when you use the Service;
- keep your account credentials secure and not share your account;
- use the Service only for your own personal, non-commercial record-keeping;
- not use the Service to track substances on behalf of any other person without that person's consent;
- comply with all laws applicable to you;
- not misuse, interfere with, or attempt to circumvent the security or intended operation of the Service.
8. Accounts and Security
You may use parts of the Service anonymously, or you may create an account using Apple, Google, or email sign-in. You are responsible for keeping your account credentials confidential, for all activity under your account, and for keeping your device secure. Please notify us promptly at hello@tryloop.health if you become aware of any unauthorized use of your account.
You may delete your account at any time from within the App; deletion removes your stored data as described in our Privacy Policy.
Device modifications.Modifying your device's operating system — including jailbreaking, rooting, sideloading unauthorized software, or bypassing security controls — may compromise the App's security and functionality. We are not responsible for any data loss, account compromise, inaccurate output, failed notification, security issue, or malfunction resulting from such modifications.
9. Subscriptions, Billing, Trials, and Refunds
Some features of the Service require a paid subscription. Subscriptions are sold and billed through the Apple App Store using Apple's In-App Purchase system, and are subject to Apple's terms(including Apple's Standard EULA) in addition to these Terms.
- The available plans, prices, billing periods, and any free-trial or introductory offers are shown to you in the App before you purchase. Pricing, trials, and offers may vary by country, eligibility, promotion, or time of purchase, and the price and terms shown at checkout control your purchase. We may change plans, pricing, and offers at any time; changes do not affect a billing period you have already paid for.
- Free trials (where offered) convert automatically into a paid subscription unless you cancel before the trial ends. You will not be charged during a valid trial period.
- Auto-renewal:subscriptions renew automatically at the end of each billing period unless you cancel at least 24 hours before the end of the current period, in line with Apple's rules. Your account is charged for renewal through Apple.
- Managing or cancelling: manage or cancel your subscription in iOS Settings → [your name] → Subscriptions. Uninstalling the App does not cancel your subscription. We cannot cancel an Apple subscription on your behalf.
- Refunds: because billing is handled by Apple, refund requests are managed by Apple at reportaproblem.apple.com, subject to Apple's policies. Any mandatory refund or withdrawal rights you have under EU or Slovenian consumer law remain unaffected (see Section 17).
We are not responsible for charges that result from your failure to cancel before a renewal.
10. Third-Party Services
The Service relies on third-party providers to function, which currently include: the Apple App Store (app distribution and subscription billing); RevenueCat (subscription status and entitlement management); and Firebase / Google Cloud (authentication, data storage, and infrastructure). Each third-party service is governed by its own terms and policies, and this list may change over time.
We are not responsible for the acts, omissions, errors, downtime, outages, pricing, billing decisions, data handling, or availability of any third-party service, and these providers may change, restrict, or discontinue their services at any time. Your use of features that depend on a third-party service is subject to that provider's terms.
11. Intellectual Property
The Service — including the Loop name, design, interface, features, text, and brand assets, but excluding the data you enter — is owned by us and is protected by intellectual-property laws. You may not copy, modify, distribute, sell, reverse-engineer, decompile, or create derivative works from the Service without our prior written permission.
You retain ownership of the data you enter (your compounds, doses, logs, notes, and records). You grant us a limited, worldwide, non-exclusive, royalty-free licence to store, process, and display that data solely to provide the Service to you. We do not claim ownership of your personal data.
12. Feedback
If you send us ideas, suggestions, feature requests, or other feedback about the Service ("Feedback"), we may use, develop, and implement that Feedback freely, without any obligation, attribution, or compensation to you. You waive any rights you may have in Feedback to the extent permitted by applicable law.
13. Prohibited Uses
You may not use the Service to:
- violate any law, regulation, or third-party right;
- source, sell, distribute, or facilitate the illegal distribution of any controlled substance, prescription medication, or other regulated product;
- provide medical advice, diagnosis, or treatment to other people;
- impersonate any person or misrepresent your affiliation;
- submit data or content of another person without that person's consent;
- attempt to gain unauthorized access to the Service, other users' accounts, or our systems;
- reverse-engineer, decompile, or attempt to extract the source code of the Service;
- circumvent paywalls, subscription, or entitlement checks;
- use bots, scrapers, or other automated means to access the Service;
- interfere with or disrupt the Service or its infrastructure;
- use the Service for any commercial purpose without our prior written consent.
We may investigate suspected violations and may suspend or terminate access for them.
14. Disclaimer of Warranties
To the maximum extent permitted by applicable law, the Service is provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.
We do not warrant that the Service will be uninterrupted, error-free, secure, or that any reminder, notification, calculation, or other output will be timely, delivered, or accurate. Reminders and notifications are a convenience feature and depend on factors outside our control— including your device settings, operating system, notification permissions, focus/do-not-disturb modes, battery and background-process restrictions, and network connectivity — and may be delayed, duplicated, silenced, blocked, or fail to arrive. You should not rely on Loop's reminders or notifications for safety-critical decisions.
Nothing in this section limits warranties or rights that cannot be excluded under applicable mandatory consumer law (see Section 17).
15. Limitation of Liability
To the maximum extent permitted by applicable law:
- We are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, goodwill, or other intangible losses, arising out of or relating to your use of, or inability to use, the Service.
- We are not liable for any health outcome, adverse event, side effect, interaction, missed or incorrect dose, or other consequence resulting from your use of, or reliance on, the Service; for any calculation error or inaccurate output; for any failed, late, or missed reminder or notification; for any data loss or service interruption; or for the acts, omissions, or outages of any third-party service.
- Our total aggregate liability for all claims relating to the Service or these Terms shall not exceed the greater of (a) the total amount you paid for the Service (through Apple) in the twelve (12) months before the claim arose, or (b) one hundred euros (€100).
These limitations do not apply to liability that cannot be excluded or limited under applicable mandatory law — including liability for death or personal injury caused by negligence, for fraud, or for any other liability that EU or Slovenian law does not permit to be limited (see Section 17). They also do not limit the statutory rights of consumers.
16. Indemnification
To the extent permitted by applicable law, you agree to indemnify and hold us harmless from any claims, liabilities, damages, losses, and reasonable expenses (including legal fees) arising out of or relating to: your use or misuse of the Service; your breach of these Terms; your violation of any law or third-party right; any substance you track, possess, administer, or use; or your own health, medical, or treatment decisions.
17. Your Consumer Rights (EU / Slovenia)
If you use the Service as a consumer, you have mandatory rights under EU and Slovenian consumer-protection law that cannot be waived or limited by these Terms. Nothing in these Terms — including the disclaimers, the limitation of liability, the assumption of risk, the indemnification, the governing-law clause, or the dispute-resolution clause — affects those mandatory rights or removes any protection that the law of your country of residence gives you. Where any provision of these Terms conflicts with a mandatory consumer protection that applies to you, that protection prevails.
18. Business Transfers and Assignment
You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign or transfer these Terms, in whole or in part, in connection with a merger, acquisition, sale of assets, financing, reorganization, change of control, or similar transaction.
If the Service or substantially all of its assets are involved in such a transaction, your account, your data, and your subscription information may be transferred to the acquiring or successor entity as part of it, subject to applicable law and our Privacy Policy. If the acquiring entity intends to materially change how your personal data is handled, it will provide notice and obtain any consent required by applicable law before those changes take effect. These Terms bind and benefit the parties and their permitted successors and assigns.
19. Termination
You may stop using the Service and delete your account at any time from within the App. We may suspend or terminate your access if you materially breach these Terms, misuse the Service, use it unlawfully, or where we are required to do so by law or by a platform or service provider. On account deletion or termination, your data is handled as described in our Privacy Policy, and any active subscription must be cancelled separately through Apple to stop further billing.
Provisions that by their nature should survive termination will survive — including those on the Medical Disclaimer, Feature-Specific Disclaimers, No Sourcing, Intellectual Property, Feedback, Disclaimer of Warranties, Limitation of Liability, Indemnification, Consumer Rights, Business Transfers, Governing Law, and Dispute Resolution.
20. Force Majeure
We are not liable for any failure, delay, or interruption in providing the Service caused by events beyond our reasonable control, including acts of God, natural disasters, war, civil unrest, government or regulatory action, power or internet failures, cloud-provider or app-store outages, or other third-party service failures. This does not affect any mandatory consumer rights under Section 17.
21. Governing Law and Dispute Resolution
Provider and governing law. The Service is provided by Rok Popovic, an individual based in Slovenia. These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the Republic of Slovenia, without regard to conflict-of-laws rules. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of residence.
Informal resolution first. Before starting any formal proceeding, please contact us at hello@tryloop.health and give us at least thirty (30) days to resolve the matter informally.
Arbitration and class-action waiver (subject to mandatory law). To the extent permitted by applicable law, any dispute that cannot be resolved informally shall be settled by binding individual arbitration rather than in court, and you and we each waive the right to participate in any class or representative proceeding. You may opt out of this arbitration agreement by emailing hello@tryloop.health within thirty (30) days of first accepting these Terms, including your name, account email, and a clear statement that you wish to opt out.
Consumers' right to courts. If you are a consumer, this arbitration agreement and class-action waiver may be unenforceable against you, and nothing in this section limits your right to bring proceedings before the competent courts of your country of residence, or our right to bring proceedings before the courts where you are domiciled. For non-consumers, the courts of Slovenia have exclusive jurisdiction.
Exceptions. Nothing in this section prevents either party from seeking relief in small-claims court where permitted, or from seeking injunctive relief in court to protect intellectual-property rights or address unauthorized access or misuse of the Service.
22. Time Limit on Claims
To the extent permitted by applicable law (and except where a longer period is required by mandatory law for consumers), any claim arising out of or relating to these Terms or the Service must be brought within one (1) year after the claim arose, or it is permanently barred.
23. Apple App Store Terms
You acknowledge that these Terms are between you and us only, not with Apple, and that Apple is not responsible for the Service or its content. Apple has no obligation to provide any maintenance or support for the Service. To the maximum extent permitted by law, Apple has no warranty obligation with respect to the Service, and any claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty are our responsibility, not Apple's. Apple is not responsible for addressing any claims by you or a third party relating to the Service or your possession or use of it, including product-liability, regulatory, or intellectual-property claims. You must comply with the Apple Media Services / App Store Terms of Serviceand any usage rules in Apple's Standard EULA. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
24. Changes to These Terms
We may update these Terms from time to time to reflect changes in the Service, the law, or our practices. When we do, we will update the "Last updated" date above and, where required by law or for material changes, provide reasonable notice. Your continued use of the Service after changes take effect means you accept the updated Terms. If you do not agree, stop using the Service.
25. No Waiver
Our failure to enforce any provision of these Terms is not a waiver of that provision or any other. Any waiver must be in writing to be effective.
26. Severability and Entire Agreement
If any provision of these Terms is held invalid or unenforceable, that provision will be limited or removed to the minimum extent necessary, and the remaining provisions will stay in full force. These Terms, together with our Privacy Policy, are the entire agreement between you and us regarding the Service and replace any prior agreements on that subject.
