Effective date: July 22, 2026
These Terms of Use (“Terms”) govern your access to and use of the Caffwise mobile application and related websites (collectively, the “Service”), provided by Savannah Altman, an individual developer (“Caffwise,” “we,” “us,” or “our”).
By downloading, installing, accessing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
These Terms are a legal agreement between you and Savannah Altman. They are not an agreement with Apple Inc. (“Apple”), except where Apple’s standard Licensed Application End User License Agreement or App Store terms apply to your purchase or use of the app through Apple.
You must be at least 13 years old (or the minimum age required in your country) to use the Service. If you are under 18 (or the age of legal majority where you live), you may use the Service only with the involvement and consent of a parent or legal guardian who agrees to these Terms on your behalf.
Caffwise is a personal wellness and educational tool that helps you log caffeine intake, estimate how caffeine may remain in your system over time, set goals or reduction plans, and optionally review caffeine in relation to sleep patterns (including optional Apple Health sleep data).
Caffwise is not a medical device, not a medical service, and not a substitute for professional medical advice, diagnosis, or treatment.
Caffeine amounts, active-caffeine estimates, cutoff times, sleep correlations, insights, and similar features are based on estimates, simplified models, catalog data, and information you enter. Metabolism, sensitivity, and sleep vary widely between people. Values shown in the app may be incomplete, approximate, or wrong.
You are solely responsible for decisions you make about caffeine intake, sleep, health, or lifestyle. If you are pregnant, under 18, taking medication, sensitive to caffeine, or managing a health condition, consult a qualified healthcare professional before setting or changing caffeine limits or relying on the Service.
Never disregard professional medical advice or delay seeking it because of something you read or see in Caffwise.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use Caffwise on Apple-branded products that you own or control, as permitted by the Apple App Store usage rules.
You may not:
The Service — including the Caffwise name, logos, design, software, text, graphics, drink catalog content we provide, and other materials — is owned by Savannah Altman or our licensors and is protected by intellectual property laws.
These Terms do not transfer any ownership of the Service to you. All rights not expressly granted are reserved.
You retain ownership of content you create in the app (such as your personal drink entries, notes, and logs). By using the Service, you grant us only the limited rights needed to operate features on your device (for example, storing and displaying that content locally). We do not claim ownership of your personal logs.
You agree that:
Caffwise is currently free to download and use. We may later offer paid features, including auto-renewable subscriptions or one-time in-app purchases (together, “Paid Features”). Until Paid Features are offered in the App Store, nothing in this section requires a purchase.
If you purchase Paid Features through the Apple App Store:
Prices, subscription length (for example monthly or yearly), free trial length (if any), and what is included in a Paid Feature are shown in the App Store product page and/or in the purchase flow at the time of purchase. Those displayed terms control for that purchase.
If you purchase an auto-renewable subscription:
Settings → [your name] → Subscriptions on iPhone)If a free trial is offered, unused portions of a free trial period are forfeited when you purchase a subscription covering that content, where allowed by Apple and applicable law. After a trial ends, the paid subscription begins and renews as described above unless canceled in time.
We may change, add, or remove Paid Features, pricing, or availability prospectively. Price changes for existing auto-renewing subscriptions will be handled according to Apple’s rules and applicable law (which may include advance notice and an opportunity to cancel).
Because purchases are processed by Apple, refund requests are handled by Apple under Apple’s refund policies and applicable law. We cannot issue App Store refunds directly.
To request a refund, use Apple’s process (for example, reportaproblem.apple.com or the purchase history / subscription tools Apple provides in your region).
If you contact us about a billing issue, we may help you locate Apple’s refund tools, but Apple makes the final refund decision for App Store purchases.
Nothing in these Terms limits any non-waivable consumer refund or cancellation rights you may have under the laws of your country or region.
Our collection and use of information is described in our Privacy Policy, which is incorporated into these Terms by reference.
The Service may interact with Apple platforms such as HealthKit, notifications, widgets, iCloud / CloudKit (when you are signed in to iCloud), and StoreKit (if paid features are offered later). Your use of those platforms is also subject to Apple’s terms and privacy policies.
We are not responsible for Apple services, outages, App Store availability, or changes Apple makes to its platforms.
To the extent required by Apple’s standard app license terms: Apple has no obligation to provide maintenance or support for Caffwise; in the event of a failure to conform to an applicable warranty, you may notify Apple and Apple may refund the purchase price (if any) for the app as required by Apple’s terms; and Apple is not responsible for addressing claims relating to the app or your possession/use of it, including product liability, legal/regulatory claims, consumer protection claims, or intellectual property infringement claims, except as Apple’s terms expressly provide. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms as they relate to your license to use the app, and may enforce those provisions.
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT:
Some jurisdictions do not allow certain warranty disclaimers. In those places, the disclaimer applies to the maximum extent permitted by law.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE (OR OUR AFFILIATES, CONTRACTORS, OR SUPPLIERS) BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF: (A) THE AMOUNTS YOU PAID US (IF ANY) FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) USD $10.
THESE LIMITATIONS APPLY TO CLAIMS BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY.
Some jurisdictions do not allow certain liability limitations. In those places, our liability is limited to the maximum extent permitted by law. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (for example, liability for fraud or for death or personal injury caused by negligence where such exclusion is prohibited).
To the maximum extent permitted by law, you agree to defend, indemnify, and hold harmless Savannah Altman from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; or (c) your violation of any law or third-party right.
You may stop using the Service at any time by deleting the app and canceling any active subscription through Apple.
We may suspend or terminate your access to the Service (or discontinue the Service) at any time, including if you violate these Terms or if we stop offering Caffwise. Where reasonably practicable, we will provide notice, but we are not obligated to continue operating the Service indefinitely.
Sections that by their nature should survive (including intellectual property, disclaimers, limitations of liability, indemnification, governing law, and refund/subscription provisions as applicable) will survive termination.
We may update these Terms from time to time. When we do, we will update the Effective date above. For material changes, we may also provide notice in the app or on this website. Continued use of the Service after the updated Terms become effective constitutes acceptance of the changes, except where applicable law requires a different process.
These Terms are governed by the laws of the United States, without regard to conflict-of-law principles, except where local mandatory consumer law requires otherwise.
If a dispute arises, you agree to first contact us at [email protected] and attempt to resolve it informally for at least 30 days before filing a formal claim, unless urgent injunctive relief is needed or a shorter period is required by law.
Nothing in these Terms limits any non-waivable consumer rights you have under the laws of your place of residence.
