Terms of Service

Natural Vision Method provides guided eye-comfort exercises, habit reminders, and self-administered screening tools. It is a wellness and education product.

It is not medical care, and it does not diagnose or treat any condition. The exercises are intended to support comfort, focus, and healthy screen habits. They are not a treatment for refractive error, and they are not a substitute for an eye exam. The vision tests in the app are rough self-checks — they are not clinical measurements and should never replace an examination by an optometrist or ophthalmologist.

Do not stop or change any treatment your eye-care professional has prescribed on the basis of anything in this app. If you notice sudden changes in vision, eye pain, flashes, floaters, or persistent headaches, contact a professional promptly.

You need an account to use the app. Keep your login details to yourself; you are responsible for activity under your account. You must be old enough to form a binding contract where you live, and if you are under 18 a parent or guardian should agree to these terms on your behalf.

You can delete your account at any time from Settings. Deletion removes your personal details immediately and permanently removes the remaining anonymised record after 30 days.

Premium membership is a monthly subscription. When you subscribe, you authorise us to charge your payment method the membership fee shown at checkout, and to charge it again automatically each month until you cancel.

The price and currency are shown before you confirm. If we change the price, we will tell you before it takes effect, and you can cancel first if you would rather not continue.

Payments are processed by Stripe. We do not receive or store your full card details.

You can cancel whenever you like — open Manage membership on your Account page. There is no cancellation fee and no notice period.

Canceling stops the next charge; it does not end your access immediately. You keep full membership until the end of the period you have already paid for, and access ends on that date.

If a payment fails, we will keep trying for a short while and your access continues in the meantime. If it cannot be collected, the membership ends.

Because you can cancel at any time and keep access for the period you paid for, we do not generally refund part-used months. If you were charged in error, or something went wrong, contact us and we will put it right.

Nothing here limits any statutory right to cancel or refund that you have where you live.

Please do not share your account, resell access, copy or redistribute the exercise content, or try to break, probe, or overload the service. We may suspend accounts that do.

The exercises, audio, written material, and design are ours or our licensors'. Your membership gives you a personal, non-transferable license to use them while it is active. Anything you enter — your check-ins, test results, and notes — remains yours.

We aim to keep the service running but cannot promise it will be uninterrupted. We may change, add, or remove features. If we make a change that materially reduces what your membership provides, you can cancel.

To the extent the law allows, Natural Vision Method is provided as-is, and we are not liable for indirect or consequential loss. Nothing in these terms excludes liability that cannot lawfully be excluded — including for death or personal injury caused by negligence, or for fraud.

We may update these terms. If a change is significant we will let you know in the app or by email before it applies. Continuing to use the service after that means you accept the updated terms.
