Terms of Use

Last updated: 3 October 2026

These Terms of Use apply to the Skin Hacker iOS app provided by Nazhmudin Ali Baimurzaev, based in the United Kingdom. For technical questions about how the app works, contact skin.hacker.help@gmail.com. You may also use this address for questions about these Terms or privacy-rights requests. The Privacy Policy is available in the app and explains how information is handled.

What Skin Hacker provides

Skin Hacker is a personal diary for sensitive or reactive skin, including skin affected by rosacea. You can record symptoms and everyday factors, view charts and possible associations based on your entries, and choose to receive local daily reminders. The app has no account or in-app purchases.

The app's scores, charts, percentages, impact labels, and trigger reports are calculated from the entries you make. They are descriptions of patterns in your diary, not clinical measurements, diagnoses, predictions, or proof that a factor caused or prevented a symptom. Incomplete entries, a short history, and other factors you have not recorded can affect the results. Results may change as you add, edit, or delete entries.

Health information

Skin Hacker is intended as a personal diary and general information tool. It is not intended for use as a medical device or medical service. The app does not provide a medical diagnosis, treatment recommendations, or medical advice, and it does not replace professional medical care. Always consult a qualified healthcare professional about health concerns and before making health-related decisions.

The app does not screen for, predict, prevent, monitor clinically, or treat rosacea or any other condition. It cannot assess whether your symptoms are serious or tell you which products, medicines, or treatments are safe or suitable for you. No healthcare professional reviews your entries or results through the app, and using it does not create a clinician–patient relationship.

Do not rely on the app to make medical decisions, delay seeking care, or start, stop, or change a medicine or treatment. Discuss symptoms, suspected triggers, and treatment decisions with a qualified healthcare professional. If symptoms are severe or worsening, seek prompt medical advice. If you think you have a medical emergency, contact local emergency services immediately; the app does not monitor emergencies or send alerts to clinicians.

Technical support helps with the operation of the app. It does not interpret symptoms or personal results, answer medical questions, or recommend products or treatment. Please take health questions to a qualified healthcare professional.

Your entries and use of the app

Your profile and check-ins are stored on your device, as explained in the Privacy Policy. You control what you enter and can delete individual check-ins in Profile → Daily logs. You retain any rights you have in your entries. Removing the app removes its local data from that device, but separate device backups may retain copies under your Apple settings. Please keep a device backup if you want a way to recover data after losing or replacing your device.

Use the app lawfully and only for records you are entitled to keep. We retain rights in the app and its design; your download and use of the app are also governed by Apple's standard Licensed Application End User License Agreement unless a custom agreement is provided through the App Store. These Terms add information about Skin Hacker's features and limitations and do not take away rights granted by applicable law.

Availability, changes, and responsibility

We may update the app or these Terms as the app develops. The updated Terms will be available in the app with a new date. Material changes will apply prospectively, subject to any notice or consent required by law. The app may not always be available or free from errors. We do not promise that its observations will be complete, accurate, or suitable for a particular health decision.

To the extent permitted by applicable law, we are not responsible for losses caused solely by inaccurate or incomplete information you enter, using the app outside its stated informational purpose, or device and backup services outside our control.
