Larkin: Symptom Log

Terms of Use — Larkin: Symptom Log

Effective date: 7 October 2026
Provider ("we", "us"): Tung Tran Thanh, an individual developer based in Hanoi, Vietnam · sendtoichime@gmail.com

1. Agreement and eligibility

By using Larkin: Symptom Log ("Larkin", the "App") you agree to these Terms and our Privacy Policy. You must be 18 or older. If you obtained the App from the Apple App Store, Apple's Licensed Application End User License Agreement also applies; where it governs, it prevails.

2. Medical disclaimer — please read

The App shows these statements, and they are part of these Terms:

This app does not diagnose or treat any condition.

Reports are written from what you entered. They are self-reported and are not a diagnosis.

Every page of a report you create carries:

Self-reported by the patient. Not a diagnosis.

On the cycle screen:

Estimates from your own entries. This is not medical advice.

With Insights:

Patterns, not causes. Share them with your doctor.

In addition:

3. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, for personal, non-commercial use. You may not copy, modify, reverse-engineer (except where the law allows), resell or redistribute the App.

4. Your content and reports

Your journal belongs to you and stays on your device. You are responsible for who you share a report or file with. We do not back up your journal and cannot recover it if it is lost.

5. Price

The App is currently free and has no in-app purchases. If paid features are introduced, they will be sold through the Apple App Store or Google Play under their payment, renewal, cancellation and refund rules, the price will be shown before you buy, and we will update these Terms first.

6. Disclaimer of warranties

The App is provided "as is" and "as available". To the fullest extent permitted by law we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy and uninterrupted or error-free operation.

7. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, for loss of data, or for any health decision made on the basis of the App. Our total liability is limited to the greater of (a) the amount you paid for the App in the 12 months before the claim and (b) USD 50. Nothing here limits liability that cannot be limited by law, or your statutory consumer rights.

8. Termination

You may stop using the App at any time by deleting it. We may discontinue the App. Sections 2, 6, 7 and 9 survive.

9. Governing law and disputes

These Terms are governed by the laws of Vietnam, without regard to conflict-of-law rules. This choice does not take away the protection you have under the mandatory consumer-protection laws of the country where you live. If you are a consumer in the EU/EEA or UK, you keep those protections and may bring a claim in the courts of your country of residence. Please contact us first — most problems can be solved by email.

10. Changes

We may update these Terms. We will change the effective date and, for material changes, show a notice in the App.
