By installing or using Titrate (the “App”) you enter into a legally binding agreement with PROSTACK AI LIMITED (“Operator”, “we”, “us”). Please read these Terms carefully. If you do not agree, do not use the App.
These Terms apply alongside the Apple Media Services Terms and Conditions, which govern your relationship with Apple as the App Store and payment processor.
1. Not medical advice — read this first
Titrate is a self-tracking tool. It is not a medical device, not a regulated software-as-a-medical-device under EU MDR/IVDR or the U.S. FDA, and not a substitute for professional medical advice, diagnosis, or treatment.
The App does not:
- Prescribe, dispense, supply, or recommend any medication;
- Recommend doses, titration schedules, or treatment changes;
- Diagnose conditions or interpret your data clinically;
- Replace consultations with a qualified healthcare provider;
- Verify the safety, efficacy, sourcing, or legality of any compound you choose to track.
The App does:
- Let you log your own self-reported tracking data;
- Show reference information about compounds, sourced from public FDA labels and peer-reviewed literature, with citations;
- Calculate reconstitution math from inputs you provide;
- Visualize your own logged data on charts and produce summaries from it.
AI-generated summaries (weekly, side-effect, and clinician PDF provider summary) describe patterns in data you have already logged. They are explicitly instructed not to recommend doses or diagnose, and every AI-generated paragraph is marked as AI-generated where it appears.
Always consult a qualified healthcare provider— your doctor, prescriber, or compounding pharmacist — before starting, modifying, or stopping any medication, peptide protocol, or supplement. If you experience symptoms that concern you, contact your provider or local emergency services (911 in the US, 112 in the EU). By using Titrate you acknowledge that you take full responsibility for any decisions you make about your own health.
1.1 Regulatory status — general wellness tool, not a medical device
Titrate is a general wellness and self-tracking application. It is not a medical device, medical software, SaMD, or IVD under any regulatory framework in the markets where the App is offered:
- U.S. FDA: Falls within enforcement discretion under “General Wellness: Policy for Low Risk Devices” (Sept 2019) and the “Policy for Device Software Functions and Mobile Medical Applications”guidance. The App stores user-entered data, performs arithmetic on user inputs (e.g., reconstitution math), and visualizes user-logged data. It does not diagnose, suggest treatment, or interpret data clinically.
- EU MDR (Regulation (EU) 2017/745):No “medical purpose” under Art. 2(1). Out of scope per MDCG 2019-11 wellness/lifestyle exclusion. Not an IVD under Regulation (EU) 2017/746.
- UK MHRA (UK MDR 2002): Same conclusion under MHRA wellness/lifestyle guidance.
- HIPAA: PROSTACK AI LIMITED is not a covered entity or business associate (45 CFR § 160.103). Titrate is a consumer wellness tool and does not handle PHI on behalf of any covered entity.
The user is the sole originator and interpreter of all logged data. The App makes no automated decisions producing legal or similarly significant effects under GDPR Art. 22.
2. Eligibility
You must be at least 18 years old to use Titrate and have the legal capacity to enter into a binding contract in your jurisdiction. The App is rated 12+ on the App Store, but our contractual eligibility threshold is 18+ regardless of Apple’s content rating.
3. Compound information disclaimer
Some compounds tracked in the App are FDA-approved (e.g., Ozempic, Mounjaro, Wegovy, Zepbound, Trulicity). Others are compounded under FD&C Act sections 503A or 503B (e.g., compounded semaglutide). Others are not approved by any major regulator and are sold only as research peptides with “not for human use” labeling (e.g., BPC-157, TB-500, MOTS-c, ipamorelin, CJC-1295).
Titrate labels each compound with its current regulatory status as best we can verify. The App does not endorse, recommend, sell, or facilitate the purchase of any compound. You alone are responsible for understanding and complying with the legal and medical implications of acquiring or self-administering any compound in your jurisdiction.
4. License
We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on iPhone hardware that you own or control, for your personal, non-commercial use, subject to these Terms and Apple’s App Store rules.
5. Subscription terms (Titrate Pro)
The free tier of Titrate is permanently free. Titrate Pro is an optional subscription, sold by Apple via the App Store using StoreKit 2.
- Yearly: $49.99 / year, with a 7-day free trial for new subscribers.
- Monthly: $9.99 / month.
- Local-currency pricing is set by Apple per market in line with their tier system.
Auto-renewal — required Apple disclosure: Subscriptions auto-renew at the end of each period at the then-current price unless cancelled at least 24 hours before the renewal date. To cancel, go to Settings → [your name] → Subscriptions on your iPhone. Refunds are handled by Apple at reportaproblem.apple.com.
Free trial: any unused portion of a free trial is forfeited when you purchase a subscription within the trial. Cancelling a trial 24+ hours before it ends prevents being charged.
Uninstalling: if you delete the App, your subscription continues. To stop being billed you must cancel via Apple.
Price changes: we may change Pro pricing in future, with notice via the App and email if applicable. Existing subscribers keep their current price for the remainder of the active term; renewals at the new price require your explicit consent under Apple rules.
EU/EEA right of withdrawal: consumers in the EU/EEA ordinarily have a 14-day right of withdrawal under Directive 2011/83/EU. By starting to use the digital subscription immediately upon purchase, you expressly request immediate performance and acknowledge that your right of withdrawal lapses once provision of the digital service has begun, in line with Article 16(m) of the Directive.
6. AI features — acknowledgement
Several Pro features (weekly summary, side-effect summary, clinician PDF provider summary, food-photo scan) call third-party AI providers as described in our Privacy Policy. You acknowledge:
- AI outputs are descriptive narratives generated from data you have logged. They are not clinical advice;
- AI may occasionally produce errors, omit context, or describe patterns imprecisely. You are responsible for verifying anything you act on;
- When you generate the clinician PDF, the AI-written paragraph at the top is marked “AI-generated summary · review before sharing”. You are responsible for reading it before giving it to a healthcare provider;
- AI requests are routed through our Vercel relay to OpenRouter, which routes to U.S.-based providers under contractual zero-data-retention terms. See section 4 of the Privacy Policy for the full path and section 6 for the international transfer basis.
7. Acceptable use
You agree not to:
- Use the App for any unlawful purpose;
- Reverse-engineer, decompile, disassemble, or attempt to extract source code or model weights, except to the extent permitted by mandatory law (e.g., EU Software Directive 2009/24/EC);
- Resell, sublicense, or redistribute the App;
- Submit deliberately false data to manipulate the AI summaries, charts, or rate-limit accounting;
- Probe, scan, or attempt to disrupt the AI relay or sub-processors;
- Use the App on a jailbroken or rooted device (we do not officially support those configurations);
- Use AI summaries as the basis for any medical, financial, or insurance decision affecting another person.
8. Your data
Your tracking data is stored in your private Apple iCloud container and processed as described in the Privacy Policy. We do not have a copy. If you delete the App and the associated iCloud data, your data is permanently gone — we cannot recover it. Use the in-app export (Profile → Data → Export) before deleting if you want a copy.
9. Intellectual property
The Titrate name, wordmark, app icon, all original artwork (compound line-art, empty-state illustrations, brand sheet) and the design system (typography pairings, color tokens, component library) are the proprietary intellectual property of PROSTACK AI LIMITED. You may not copy, redistribute, or create derivative works.
Compound information, half-life data, and citations are sourced from public FDA labels and peer-reviewed literature (in the public domain or properly cited). Editorial commentary about regulatory status is our copyrighted text.
Apple, Apple Health, HealthKit, CloudKit, StoreKit, Foundation Models, and Apple Intelligence are trademarks of Apple Inc. Compound brand names (Ozempic, Wegovy, Mounjaro, Zepbound, Trulicity, etc.) are trademarks of their respective owners and are used for identification purposes only.
10. Third-party services
The App relies on third-party services (Apple App Store, iCloud, HealthKit, StoreKit; Vercel; OpenRouter; AI model providers; USDA FoodData Central). Your use of those services is subject to their own terms. We are not responsible for their actions, outages, or changes in policy.
11. Disclaimer of warranties
The App is provided “as is” and “as available” without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy of calculations, or uninterrupted operation. To the extent legally permitted, we do not warrant that:
- The App will be uninterrupted, secure, or error-free;
- Calculations are accurate for every edge case;
- Compound information reflects the latest regulatory action;
- AI outputs are accurate, complete, or appropriate for your situation;
- The App will work on every iOS version, device, or region.
You use the App at your own risk. Always verify dose calculations independently before injecting anything into your body.
12. Limitation of liability
To the maximum extent permitted by applicable law, PROSTACK AI LIMITED, its directors, employees, and affiliates shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages arising from or related to your use of, or inability to use, the App. This includes damages for personal injury, medical expenses, loss of profits, goodwill, use, or data — even if we have been advised of the possibility.
Our total aggregate liability for any claim arising under or in connection with these Terms shall not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) GBP 100.
UK / EU / EEA consumers: nothing in these Terms excludes or limits liability for death, personal injury caused by negligence, fraud, or any other liability that cannot be excluded under mandatory consumer law. Mandatory rights under the UK Consumer Rights Act 2015 (for UK consumers) and the Consumer Rights Directive 2011/83/EU and applicable national implementations (for EU/EEA consumers) remain unaffected.
13. Indemnification
You agree to indemnify and hold harmless PROSTACK AI LIMITED from any claim, damage, or expense (including reasonable legal fees) arising from your use of the App, your violation of these Terms, or your violation of any third-party right or applicable law — except to the extent caused by our gross negligence or wilful misconduct.
14. Termination
You may stop using the App at any time by uninstalling it and cancelling your subscription via Apple. We may suspend or terminate your access if you breach these Terms or if continuing to provide the App becomes infeasible. Sections 1, 8, 9, 11, 12, 13, 16, and 17 survive termination.
15. Changes to these terms
We may update these Terms. Material changes will be surfaced in the App and require your re-acceptance before continued use. Minor changes (typos, clarifications) update only the effective date at the top.
16. Governing law
These Terms are governed by the laws of England and Wales, without regard to conflict-of-law principles. EU/EEA consumers retain the rights granted to them by mandatory consumer law of their habitual residence, including the right to bring actions before the courts of their home jurisdiction.
17. Dispute resolution
We hope to resolve any concern informally. Please contact hello@compoundgroup.com first. If we cannot resolve it within 30 days, the dispute may be brought before the competent courts of England and Wales — without prejudice to mandatory jurisdiction rules in your country of residence.
EU online dispute resolution: the European Commission provides an online dispute resolution platform at ec.europa.eu/consumers/odr. Note that we are not currently obliged or willing to participate in alternative dispute resolution proceedings before a consumer arbitration board.
18. Severability
If any provision of these Terms is found unenforceable, the remainder remains in full effect.
19. Entire agreement
These Terms, together with the Privacy Policyand Apple’s applicable terms, constitute the entire agreement between you and PROSTACK AI LIMITED regarding the App, superseding any prior understanding.
