These Terms of Use govern your use of Vialkeep, an iOS application published by Cloud Motion Lab LLC ("we", "our", "us"), a Wyoming limited liability company. Please read the Medical Disclaimer first. Questions: dev@slyapp.co.
Vialkeep is a calculator and a personal record. It performs arithmetic on numbers you enter and stores the log you create. It is not medical advice, it is not a medical device, it is not a pharmacy, and it is not a substitute for a licensed healthcare professional.
Vialkeep does not contain, suggest, prefill, recommend, endorse, or evaluate any dose, concentration, schedule, peptide, compound, product, brand, or protocol. Every figure in the app is a figure you typed. If you enter a wrong number, the app will faithfully calculate a wrong answer.
Do not use Vialkeep to decide what to take, how much to take, or whether to take anything at all. Those are decisions for you and a qualified clinician. Many substances people track in apps like this are not approved for human use in your jurisdiction, are available only by prescription, or are restricted; determining what is lawful and appropriate for you is entirely your responsibility. Always independently verify any calculation before acting on it. If you are experiencing a medical emergency, call your local emergency number.
By downloading, installing, or using Vialkeep, you agree to these Terms and to the Privacy Policy. If you do not agree, do not use the App and delete it. Where the App presents an in-app disclaimer or acceptance screen that references these Terms, your action on that screen is an additional, express acceptance, and does not replace or narrow this one.
You must be at least 18 years old, and at least the age of legal capacity in your jurisdiction, to use Vialkeep. The App is not directed to children and is not appropriate for them. We do not knowingly allow users under 13, and we do not permit use by minors on a guardian's acceptance, because of the subject matter. If we learn that a user is under 18, we may terminate access.
Vialkeep provides: a reconstitution and dose calculator that operates on values you enter; a record of the vials you create; a schedule and local reminder facility; a calendar and log of doses you record, including retroactively; and export of your own record as a CSV file. Some features require a paid subscription. Features may change, and we may add, modify, or remove functionality at any time.
Vialkeep ships with no dosing database and no default values. Empty fields are a deliberate design decision, not an omission.
You are solely responsible for the accuracy of every value you enter, for the correctness of the syringe type you select, for verifying the App's output against your own independent calculation, and for the consequences of any action you take. We make no representation that the App's arithmetic is fit for any clinical, therapeutic, veterinary, research, or other particular purpose. Unit selection in particular is yours: the App echoes the unit you typed and never converts or promotes it on your behalf.
Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to use Vialkeep on Apple-branded devices that you own or control, as permitted by the Apple Media Services Terms and the Usage Rules therein. All rights not expressly granted are reserved. You may not copy, modify, reverse engineer, decompile, disassemble, rent, lease, lend, sell, redistribute, or sublicense the App, except to the extent that restriction is prohibited by applicable law.
The records you create in Vialkeep are yours. We do not receive them, we do not claim any license to them, and we cannot access them. Because they are stored on your device and, at your option, in your own iCloud account, you alone are responsible for keeping them and for backing them up. Deleting the App may delete local data permanently. We are not able to restore a record we never held.
Vialkeep offers auto-renewing subscription plans. Plan names, durations, and prices are displayed in the App at the time of purchase, in your local currency, and are the controlling statement of what you will be charged. Any free trial or introductory offer, and its length, is displayed on the same screen before you buy.
By tapping the purchase button, you agree your subscription will automatically renew at the price and period shown until you cancel. Payment is charged to your Apple Account at confirmation of purchase. The account is charged for renewal within 24 hours prior to the end of the current period at the displayed cost. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. You manage and cancel subscriptions yourself in iPhone Settings, Apple Account, Subscriptions. Any unused portion of a free trial is forfeited when a paid subscription is purchased.
Purchases are processed by Apple, not by us. Refunds are handled by Apple under the Apple Media Services Terms; we cannot issue, approve, or deny a refund, and requests should go to Apple at reportaproblem.apple.com. Where your local law grants a statutory right of withdrawal or cancellation, that right is not waived by these Terms.
The App is provided "as is" and "as available", without warranty of any kind, whether express, implied, statutory, or otherwise, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the App will be uninterrupted, error-free, or free of harmful components, that any calculation will be correct for your circumstances, that reminders will be delivered at any particular time, or that data will sync, persist, or be recoverable. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you, and nothing here limits any non-waivable statutory warranty or consumer guarantee you have under the law of your country of residence.
To the maximum extent permitted by applicable law, Cloud Motion Lab LLC will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, or goodwill, arising out of or relating to your use of or inability to use the App, whether based in contract, tort, strict liability, or any other theory, and whether or not we were advised of the possibility. Our total aggregate liability for all claims relating to the App will not exceed the greater of the amount you paid us for the App in the twelve months before the event giving rise to the claim, or twenty United States dollars.
Nothing in these Terms excludes or limits liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under applicable law. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.
You will indemnify and hold harmless Cloud Motion Lab LLC and its members, officers, and agents from any claim, demand, loss, or expense, including reasonable legal fees, arising out of your misuse of the App, your violation of these Terms, your violation of any law, or any decision you or another person made in reliance on output from the App. This does not apply to the extent the claim arises from our own gross negligence or wilful misconduct.
We will defend you against a third-party claim that the App, as provided by us and used in accordance with these Terms, directly infringes that party's intellectual property rights, and we will pay any resulting award or settlement we agree to, provided you notify us promptly, give us sole control of the defence, and cooperate reasonably. This is our entire obligation for infringement claims.
Read this section carefully. It limits your right to bring a court action and a class action.
Informal Resolution Period. Before either of us starts an arbitration, you and we agree to try to resolve the dispute informally for 60 days. To start the period, you send a written notice to dev@slyapp.co describing the claim, the relief you want, and your contact information. We will send our notice to the email address associated with your Apple Account where available, or otherwise to the contact you have provided. The 60-day period tolls any statute of limitations.
Binding Individual Arbitration. If the dispute is not resolved informally, any dispute between you and us arising out of or relating to Vialkeep or these Terms will be resolved by individual binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules then in effect, in the county of your residence, or, at your election, by video. The Federal Arbitration Act governs the interpretation and enforcement of this provision.
Class, Collective, and Representative Action Waiver. You and Cloud Motion Lab LLC waive any right to bring or participate in any class, collective, consolidated, or representative proceeding. The arbitrator may award relief only to the individual party seeking it. If this waiver is held unenforceable as to a particular claim, that claim proceeds in court and the rest of this section still applies to all other claims.
Mass-Arbitration Batching. If 25 or more similar claims are asserted against us by or with the coordination of the same or coordinated counsel, the claims will be filed and adjudicated in batches of no more than 50, with a single arbitrator per batch and one filing fee per batch, and the results of the first batches may be used to negotiate resolution of the remainder. Statutes of limitation are tolled for claims awaiting a batch.
Small Claims. Either of us may bring an individual action in small claims court instead of arbitration if it qualifies.
Opt-Out. You may opt out of this arbitration and class-waiver section by emailing dev@slyapp.co with the subject "Arbitration Opt-Out" within 30 days of first accepting these Terms. Opting out affects nothing else in these Terms and will not disadvantage you in any way.
These Terms are governed by the laws of the State of Wyoming, where Cloud Motion Lab LLC is organized, without regard to conflict-of-laws principles, except that the consumer-protection laws of your home state or country may also apply and any rights they grant you are not waived by these Terms. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Subject to the Arbitration section, any judicial proceeding will be brought exclusively in the state or federal courts located in Sheridan County, Wyoming, and you and we consent to the personal jurisdiction of those courts. If you are a California consumer, the venue restriction of California SB 940 applies and you may bring qualifying disputes in the California state court of your county of residence. If you are a consumer resident in the European Union or the United Kingdom, you may bring proceedings in the courts of your country of residence and nothing here removes that right.
To the extent any dispute proceeds in court rather than arbitration, you and we each waive any right to a class, collective, or representative action, and to a jury trial, to the maximum extent permitted by applicable law.
Neither party is liable for a failure or delay caused by an event beyond its reasonable control, including acts of God, natural disaster, war, terrorism, civil unrest, labour dispute, governmental action, network or platform outage, or failure of a third-party service including the Apple App Store, iCloud, or any subprocessor.
You may not assign these Terms without our prior written consent. We may assign them in connection with a merger, acquisition, reorganisation, or sale of assets, on notice to you.
These Terms and the Privacy Policy, together with the Apple Media Services Terms and any in-app purchase disclosure, are the entire agreement between you and us regarding Vialkeep, and supersede any prior understanding on that subject.
We give notice through the App, through this page, or, where available, to the email address associated with your Apple Account. You give notice to dev@slyapp.co or to Cloud Motion Lab LLC, 30 N Gould St Ste R, Sheridan, Wyoming 82801, United States.
A failure to enforce any provision is not a waiver of it. A waiver is effective only if in writing and signed by the waiving party.
If any provision is held unenforceable, it is modified to the minimum extent necessary to be enforceable, or severed if it cannot be, and the remaining provisions continue in full force.
We may update these Terms. For material changes, including changes to price structure, to the arbitration or dispute-resolution provisions, or to the scope of what the App does, we will give at least 30 days' advance notice through an in-app banner and by updating the effective date at the top of this page. Minor changes such as typographical or formatting fixes may be made without separate notice. Continued use of the App on or after the effective date constitutes acceptance. If you do not accept a material change, stop using the App and cancel any subscription before the effective date.
You and we acknowledge that these Terms are concluded between you and Cloud Motion Lab LLC only, and not with Apple, and that Cloud Motion Lab LLC, not Apple, is solely responsible for Vialkeep and its content. Apple has no obligation to furnish any maintenance or support for the App, and no warranty obligation with respect to it. Apple is not responsible for addressing any claim relating to the App, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation. You and we further acknowledge 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 thereof.
You represent that you are not located in a country subject to a United States Government embargo or designated as a terrorist-supporting country, and that you are not on any United States Government list of prohibited or restricted parties. You will comply with all applicable export control laws in using the App.
You may terminate these Terms at any time by deleting the App and cancelling any subscription through Apple. We may suspend or terminate your access if you materially breach these Terms, if required by law, or if we discontinue the App. Sections that by their nature should survive termination will survive, including Your Responsibility for Accuracy, Disclaimer of Warranty, Limitation of Liability, Indemnification, Arbitration, and Governing Law. Termination does not entitle you to a refund except where required by law or granted by Apple.
