Terms & Conditions

Vitalens · Last updated 19 September 2026

Vitalens measures your pulse and heart rate variability with the front camera. It is a wellness tool for general wellbeing, not a medical device.

1. Who you are agreeing with

Vitalens is published by Safiye Meram, Esenler/Istanbul, Türkiye. You can reach the publisher at gelistirbizi@gmail.com. By installing or using the app you accept these terms. If you do not accept them, do not use the app.

2. Not a medical device, which is the important clause

Vitalens is not a medical device and is not intended to diagnose, treat, cure or prevent any disease or condition. It cannot detect atrial fibrillation, any other arrhythmia, or any cardiac or circulatory disorder, and the absence of an unusual reading means nothing about your health.

Do not use Vitalens to make a medical decision, to decide whether to seek care, or to judge whether a symptom is serious. If you feel unwell, if your heart behaves in a way that worries you, or if you have any concern at all about your cardiovascular health, contact a qualified clinician or your local emergency service.

3. What the measurement can and cannot do

The app reads a pulse optically, from light reflected off your face. That is an indirect measurement and it depends on things outside the app's control: how evenly you are lit, how still you hold your head, your skin, and your camera.

  • A reading needs a face in the guide, reasonably even light, and about fifteen seconds of stillness.
  • In poor conditions the app refuses to produce a reading rather than producing a bad one.
  • Heart rate variability needs a cleaner signal than pulse rate does. When the recording is not good enough for it, the app says so on the report and leaves that reading out of your baseline and your trends.
  • Readings are not comparable with a chest strap or an electrocardiogram and should not be treated as equivalent.

4. Your licence

You get a personal, non-transferable licence to use Vitalens on devices you control. You may not resell it, rent it, reverse engineer it, or present its output as a medical or diagnostic service.

5. Purchases

Vitalens is free to install and includes two measurements per day. Vitalens Pro removes that limit and unlocks the full variability panel, trends, the personal baseline, guided breathing and data export. It is sold as a monthly or yearly subscription, or as a single lifetime payment.

  • Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends.
  • Your account is charged for renewal within 24 hours before the period ends.
  • Manage and cancel in your App Store or Google Play account settings. Uninstalling the app does not cancel a subscription.
  • The lifetime option is a single payment and does not renew.
  • Purchases are handled entirely by Apple or Google. Refunds follow their policies, not ours.

On iOS, use of the app is also governed by the Apple Standard EULA.

6. Your data

Your measurements are stored on your device and nowhere else. That has a consequence worth stating plainly: they do not reach a second device, and deleting the app deletes them. See the Privacy Policy.

7. Liability

The app is provided as it is, without warranty of accuracy or fitness for a particular purpose. To the fullest extent permitted by law the publisher is not liable for any decision taken on the basis of a reading, nor for lost measurements. Nothing here limits liability that cannot be limited by law, including for death or personal injury caused by negligence.

8. Age

Vitalens is intended for people aged 13 and over and is not directed to children.

9. Changes and governing law

Material changes to these terms will be published on this page with a new date. These terms are governed by the laws of the Republic of Turkiye.
