Terms of Service

Acceptance

By installing or using the Pink Vein iOS app (“Pink Vein”, “the app”), you agree to these Terms of Service. If you do not agree, do not install or use the app.

Pink Vein is published by Danielius Studio LLC, a Wyoming limited liability company at 30 N Gould St, Suite #5280, Sheridan, WY 82801, USA (“we”, “us”).

What Pink Vein is

Pink Vein is a manual blood-pressure and pulse log for iPhone. You type three numbers (systolic, diastolic, pulse) plus an optional memo, and the app stores the entry on your device via SwiftData. Free users see the last 7 days; Pro users see the full year, get the trend chart PDF export, and the Lock Screen widget.

The app makes no network calls except to Apple's StoreKit for in-app purchases. See the Privacy Policy for details.

Not a medical device

Not a medical device. Pink Vein does NOT diagnose, treat, cure, or prevent any condition. The numbers come from whatever monitor you use; the app is a journal, not a sensor. For health concerns, consult a qualified clinician. Pink Vein is intended for personal record-keeping only and is not a substitute for professional medical advice, diagnosis, or treatment.

Do not rely on Pink Vein for any clinical decision. If you experience symptoms or have questions about your readings, contact a qualified healthcare professional.

License

We grant you a personal, non-exclusive, non-transferable license to use Pink Vein on iOS devices you own or control, subject to Apple's standard App Store Licensed Application End User License Agreement (the “EULA”) which is incorporated by reference: apple.com/legal/internet-services/itunes/dev/stdeula. Where these Terms and the Apple EULA conflict, the Apple EULA controls.

Free window and subscriptions

When you first install Pink Vein, every feature is unlocked for three days with no payment and no account. This is a no-strings free window, not a trial signup.

After the three-day window, you may continue using the app for free with the last 7 days of history visible, OR start the Pink Vein Pro Monthly subscription, which begins with a 14-day Apple intro offer and then renews at $4/month. You may also purchase Annual ($25/year) or Lifetime ($59 one-time) at any time from the Settings screen.

All payments are processed through Apple's StoreKit and are subject to Apple's standard subscription terms, including auto-renewal. You can manage or cancel subscriptions at any time in the iOS Settings → Apple ID → Subscriptions screen.

The Lifetime tier is a one-time non-consumable purchase. It remains active for as long as Apple keeps Pink Vein available on the App Store under your Apple ID.

Acceptable use

You agree not to reverse engineer, modify, redistribute, or create derivative works of Pink Vein, except to the extent expressly permitted by applicable law. You agree to use Pink Vein only for lawful, personal record-keeping purposes.

Disclaimers

Pink Vein is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

To the maximum extent permitted by law, Danielius Studio LLC will not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of, or inability to use, the app, including any decisions you make based on the entries you log in Pink Vein.

Apple as third-party beneficiary

You acknowledge that these Terms are between you and Danielius Studio LLC, not Apple, and that Apple is not responsible for Pink Vein or its contents. Apple is a third-party beneficiary of these Terms and may enforce them against you.

Governing law

These Terms are governed by the laws of the State of Wyoming, USA, without regard to conflict-of-laws principles. Any dispute will be resolved in the state or federal courts located in Sheridan County, Wyoming, except where Apple's EULA requires otherwise.

Changes

We may update these Terms from time to time. Material changes will be reflected in the “Last updated” date at the top. Continued use of Pink Vein after a change constitutes acceptance of the new Terms.
