Terms of Use

These Terms explain the basic rules for using Sipline. Sipline is provided by Peter Hlavatik.

App license

Sipline is licensed, not sold. Your use of Sipline is also governed by Apple platform terms and the App Store terms that apply to apps downloaded through Apple.

Hydration tracking

Sipline provides general hydration tracking, reminders, widgets, Apple Watch surfaces, Siri Shortcuts, and insights. Sipline is not medical advice and is not a medical device.

If you have medical conditions, pregnancy-related hydration concerns, kidney or heart issues, medication-related fluid limits, or other health questions, consult a qualified healthcare professional.

Sipline uses these sources for general hydration context: National Academies Dietary Reference Intakes for Water (https://www.nationalacademies.org/read/10925/chapter/6), CDC About Water and Healthier Drinks (https://www.cdc.gov/healthy-weight-growth/water-healthy-drinks/index.html), and MedlinePlus Dehydration (https://medlineplus.gov/dehydration.html).

Free access and earlier purchases

Sipline is completely free. This version has no paywalls, subscriptions, or in-app purchases.

If you subscribed through an earlier version, updating or deleting Sipline does not itself cancel that subscription. Manage or cancel any remaining subscription in Apple subscription settings. Apple handles billing and refund requests for earlier purchases.

For help managing an earlier purchase, see support.apple.com/en-us/118428 or request a refund through reportaproblem.apple.com.

No warranty and limitation of liability

Sipline is provided "as is" and "as available" without warranties of any kind, to the maximum extent permitted by law.
