Terms of Use
Last updated: October 6, 2026 · Effective for RanchStack at ranchstack.ai
RanchStack (ranchstack.ai, formerly PeptiLogger) is a personal record-keeping tool operated by 48U Ranch LLC, doing business as 48U Technology Development (“48U”, “we”). By creating an account or using the application you agree to these terms. If you do not agree, do not use it.
1. What RanchStack is
RanchStack is an inventory, scheduling and record-keeping application for personal research tracking. It records what you tell it, does arithmetic on it, and shows it back to you in reports. It does not supply, source, recommend, or endorse any substance, vendor, or protocol.
2. Not medical advice
Nothing in the application — including the knowledge base, reference ranges, cautions, calculators, projections, beyond-use dates, regulatory notes, or any generated report — is medical advice, and none of it substitutes for the judgment of a qualified professional. Compounds referenced in the application are frequently research chemicals that are not approved for human use. Decisions about any substance, dose, route, or protocol are yours and your clinician’s alone.
The application does not establish that any substance, dose, route, preparation, or protocol is safe, lawful, or appropriate for human use. Calculations depend on the inputs and units entered and should be independently verified. Estimated beyond-use dates do not establish sterility, stability, or potency.
3. The knowledge base and reference prices
The shipped knowledge base is reference material compiled from published literature and public regulatory sources, with citations and a review date on each entry. It is provided for context, may be incomplete or out of date, and is not verified for accuracy by any clinician or regulator. Evidence tiers, confidence labels and regulatory flags are our editorial summaries, not legal or medical determinations. You may add, edit or hide entries for your own account; entries you add are yours and are not reviewed by us.
Reference list prices shipped with the application are hand-maintained estimates for the vendor named, are not offers, and may be wrong. Prices you enter are used in preference to them. Vendor names and links appearing in the application identify where records came from; they are not recommendations.
4. Eligibility
You must be at least 18 years old and legally able to enter into these terms. The application is not for use by, or for recording data about, minors. By registering, you confirm that you meet these requirements. If we learn that an account or record concerns a minor, we may restrict access and remove the information, subject to applicable law.
5. Your responsibilities
- The accuracy of everything you enter, and the consequences of acting on it.
- Keeping your password, authenticator and passkeys secure, and telling us promptly if you believe your account has been compromised.
- Keeping your own exports as backups. The application makes a complete export available at any time.
- Complying with every law and regulation that applies to you and to any substance you record, in your jurisdiction.
- Having the agreement of any other person whose data you record under your account, and honoring their requests about it.
6. Your data
Your data is yours. We claim no ownership of it. You grant us only the license needed to store, process, back up and display it in order to provide the application to you. How it is handled is described in the Privacy Policy, which forms part of these terms.
7. Acceptable use
Do not attempt to access another account’s data, probe, overload or degrade the service, reverse-engineer its security, or use the application to store unlawful content or to facilitate unlawful activity. Accounts used in these ways may be suspended or removed without notice.
8. The service
The application is provided as-is and as-available, without warranty of any kind, express or implied, including fitness for a particular purpose. It is maintained on a best-effort basis for its own users; availability, correctness, and continuity of service are not guaranteed, and features may be changed or removed. We may suspend the service for maintenance or security at any time.
9. Limitation of liability
To the fullest extent permitted by law, 48U Ranch LLC d/b/a 48U Technology Development, its members, and anyone working on its behalf are not liable for any loss or damage — direct, indirect, incidental, consequential, or otherwise, including loss of data, health outcomes, or regulatory consequences — arising from your use of or inability to use the application, or from reliance on anything it displays. To the extent permitted by law, our total liability is limited to the greater of US $100 or the fees you paid for the service in the twelve months preceding the event giving rise to the claim. The exclusions and limits in this section do not apply to fraud, willful misconduct, gross negligence, or liability that applicable law does not permit us to exclude or limit.
10. Intellectual property
The application, its code, design, knowledge-base text and the RanchStack name and marks are the property of 48U Ranch LLC d/b/a 48U Technology Development. You may use the application for your own personal research tracking; you may not copy, resell, or redistribute it or its knowledge base.
11. Paid subscriptions
This section applies if and when a paid plan is offered. Price, billing frequency, renewal terms, and any trial conditions are disclosed before purchase. Automatic renewal requires your express authorization. You may cancel renewal through the store or account settings where you subscribed; access continues through the paid period. Refunds follow the refund policy disclosed before purchase, subject to applicable law. We provide any legally required notice of price changes. If we permanently discontinue prepaid service, we refund the unused subscription period. Cancellation does not itself delete your records; retention and deletion follow the Privacy Policy.
12. Ending an account
You may stop using the application at any time and may ask for your account and all its data to be deleted via the contact below. We may end an account for breach of these terms, or if the service is discontinued, in which case we will make reasonable efforts to give notice and time to export.
13. Changes to these terms
These terms may be revised as the application evolves. The date at the top is the current revision. Material changes are presented in the application for you to accept before continued use; your acceptance, its date and the exact wording accepted are recorded against your account.
14. Governing law
These terms are governed by Texas law, except where applicable law requires otherwise. Disputes must be brought in the state or federal courts serving Montgomery County, Texas, unless applicable law gives you a right to bring a claim elsewhere. Nothing in these terms limits rights or remedies that cannot legally be waived. If any part of these terms is found unenforceable, the rest remains in effect. These terms and the Privacy Policy are the entire agreement between you and 48U about the application.
