SpineAlign · Last updated %-d %B %Y

SpineAlign measures the angle of your head and neck while you work at a desk, using the front camera. Everything is computed on the device and no image is ever saved.

Who provides this app

SpineAlign is published by Safiye Meram, Esenler/Istanbul, Türkiye. You can reach us at gelistirbizi@gmail.com.

What SpineAlign does

  • Takes a single frame from the front camera every three to five seconds while a tracking session is running, and finds the position of your ear, shoulder and hip in it.
  • Calculates the craniovertebral angle, which is the angle between the horizontal and the line from your shoulder to your ear, and compares it against the thresholds commonly used to describe a forward head posture.
  • Estimates the additional load this angle places on the cervical spine, in kilograms, using a published biomechanical model.
  • Times how long you have been in a poor posture and how long you have been sitting without a break.
  • Plays a quiet chime, a light vibration, or nothing at all when posture has been poor for a while. You choose which.
  • Guides a sixty second chin tuck exercise and, when the camera can see you clearly, shows how much of the movement you are actually holding.
  • Keeps hourly totals on the device so you can see how the day went, and with Pro produces a weekly PDF report.

What SpineAlign never does

  • It does not record video or take photographs. Each camera frame is turned into a handful of coordinates in memory and released immediately. There is no code in the app that writes a frame to a file and no code that transmits one.
  • It shows a camera preview only as a preview: dimmed, behind the skeleton, to help you position yourself, and only if you leave that setting on. The image is never written down or sent.
  • It uses the camera only while you have a session, a calibration or the guided exercise running, or while the posture screen is open and showing you the preview so you can aim the phone. There is no background tracking and the app declares no background modes: closing or switching away from the app ends the session.
  • It does not identify you, recognise your face or build a face template. Nothing it computes could be used to tell one person from another.
  • It has no account, no sign-in and no cloud sync.
  • It shows no advertising and contains no analytics or tracking.

This is a wellbeing tool, not a medical device

SpineAlign is for comfort and ergonomics at a desk. It does not diagnose, treat, cure, prevent or screen for any condition, including neck pain, cervical radiculopathy, disc disease or postural kyphosis. It is not a substitute for an examination by a doctor or a physiotherapist.

The angle it reports is an estimate produced from a phone camera and a pose model, not a clinical measurement, and the load figures in kilograms come from a published biomechanical model of an average adult head rather than from any measurement of your own spine. Neither should be used to make a medical decision.

If you have neck or arm pain, numbness, tingling, weakness, dizziness, or pain that wakes you at night, stop using the exercise and see a clinician.

The exercise, and your own safety

  • The chin tuck guide is a general mobility exercise. It has not been prescribed for you and it is not tailored to any injury or condition you may have.
  • Do it slowly, within a range that is comfortable, and stop immediately if anything hurts. Never force the movement.
  • If you are pregnant, recovering from surgery or an injury, have had neck or spine surgery, or are under the care of a clinician for any neck or back problem, ask them before doing it.
  • You take part at your own risk, and you are responsible for deciding whether an exercise is appropriate for you.

Purchases

  • Ninety minutes of tracking a day, the live posture screen, calibration, the chin tuck guide and seven days of history are free.
  • SpineAlign Pro removes the daily limit and unlocks the hourly spinal load map, the nudge profiles and their timing, history beyond the last seven days, the weekly PDF report and CSV export.
  • Pro is sold as a monthly subscription, a yearly subscription or a one time lifetime purchase. Prices are shown in your own currency on the purchase screen before you buy.
  • Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel them in your App Store or Google Play account, not in the app.
  • The lifetime purchase is a one time payment. It does not renew and there is nothing to cancel.
  • Purchases on iOS are governed by the Apple Standard EULA; purchases on Android by Google Play's terms. Refunds are handled by the store you bought from, under its own policy, not by us.

Your data

Everything SpineAlign records stays on your device. We have no server and cannot see it. The privacy policy explains exactly what is kept and how to erase it.

Acceptable use

  • Use the app only for yourself, and only while the device is stationary and you are seated safely. Do not use it while driving or operating machinery.
  • Do not point the camera at anybody who has not agreed to it.
  • Do not decompile, resell or redistribute the app, or try to circumvent the purchase checks.

Liability

The app is provided as is, without warranty of any kind. To the extent permitted by law we are not liable for any injury, loss or damage arising from using it, from relying on its measurements, or from performing the exercise it guides. Nothing here limits liability that cannot be limited by law, including for death or personal injury caused by negligence, and nothing affects your statutory rights as a consumer.

Changes

We may update these terms when the app changes. The date at the top of this page is the date of the current version, and continuing to use the app after a change means you accept it.

Governing law

These terms are governed by the laws of the Republic of Türkiye. This does not remove any protection you have under the law of the country you live in.
