Terms of Use
Effective October 4, 2026.
Waterline is provided by Roscommon Group LLC for personal drink-intake tracking. By using the app, you agree to these terms and applicable Apple terms.
Personal tracking
Waterline records entries you provide. It does not diagnose, treat or prevent a condition, provide medical advice, or determine an appropriate fluid intake. The initial goal is an editable starting value, not an individualized recommendation. Follow advice from your qualified healthcare professional, including any fluid restrictions. Records, totals, dates and Health synchronization may be delayed or inaccurate; verify important information.
Trial and purchase
The seven-day free trial begins on first use. After it ends, logging in the app and widgets requires a one-time non-consumable purchase: US$9.99 or the localized App Store price. No automatic charge occurs when the trial ends. Existing entries remain readable. Restore a purchase with the same Apple Account. Apple administers payment and refunds under its policies and applicable law. An unlock provides access to the purchased features while the app and supported platforms remain available; it is not a promise of perpetual availability or compatibility.
Your records and Apple Health
Your log stays on this device and is not backed up or synchronized by Roscommon Group. Keep separate copies of important information. All drink volumes count toward your chosen local goal. Optional Health sharing starts with new entries marked Water after you enable it; other drink types are not sent to Health. Widget records sync when you open the app. Locked devices, denied permissions, system limitations and errors can delay or prevent synchronization. Turning sharing off does not remove existing Health records.
Availability and responsibility
To the extent permitted by law, the app is provided as is and as available without warranties of accuracy, fitness for a particular purpose or uninterrupted availability. Roscommon Group LLC and its owners, officers, employees, contractors and agents are not liable for indirect, incidental, special or consequential losses arising from use of the app. To the extent lawful, aggregate liability is limited to the greater of the amount you paid for Waterline in the preceding twelve months or US$100. Mandatory consumer protections and liabilities that cannot legally be excluded remain unaffected.
Disputes
Before formal proceedings, send written notice describing the dispute and requested relief and allow 30 days for informal resolution. Except for eligible small-claims cases, public injunctive relief where applicable and claims that cannot lawfully be arbitrated, disputes will be resolved through binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules. The Federal Arbitration Act governs. Arbitration will be remote where available or in Bellevue, Washington, unless applicable law or arbitration rules require otherwise. Roscommon Group will pay fees it is required to pay under those rules. Claims must be brought individually, not as class or representative actions, to the extent permitted by law.
You may opt out of arbitration within 30 days after first accepting these terms by contacting support with your name, the date of acceptance and a clear statement that you opt out. For disputes not subject to arbitration, Washington law and the state and federal courts in King County apply, subject to mandatory consumer rights. If a provision is unenforceable, the remainder remains effective.
