Terms of Use

Last updated 28 July 2026

These Terms of Use ("Terms") are an agreement between you and BNM FABRİKA BİYO NANO MİKRO TEKNOLOJİ SANAYİ VE TİCARET LİMİTED ŞİRKETİ ("Dichoptix", "we", "us") governing your access to and use of the Dichoptix mobile game, the dichoptix.com website, the user dashboard, the supervisor panel, and related services (together, the "Service"). Please read them carefully. By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Who we are and how to reach us

The Service is provided by BNM FABRİKA BİYO NANO MİKRO TEKNOLOJİ SANAYİ VE TİCARET LİMİTED ŞİRKETİ, a company registered in Türkiye at Kaleiçi Mah. Piyale Sk. Meryem Yıldız Sitesi No: 8C, Çatalca, İstanbul (trade registry / MERSIS no. 0178070122100010).

You can contact us at info@dichoptix.com for any question about the Service or these Terms.

2. What Dichoptix is, and what it is not

Dichoptix is a gamified vision-training tool designed to support therapy for amblyopia ("lazy eye") and related binocular-vision conditions. It uses dichoptic, anti-suppression exercises intended to be used alongside, and under the direction of, a qualified eye-care professional.

Dichoptix is NOT a medical device, is not a substitute for professional medical advice, diagnosis, or treatment, and has not been cleared or certified by any medical regulator (for example, it is not FDA-cleared or CE-marked as a medical device). It does not diagnose any condition and does not guarantee any clinical outcome or improvement.

Always seek the advice of a qualified eye-care professional before starting, changing, or stopping any therapy, and follow their instructions. Never disregard or delay professional advice because of something you experienced in the Service. If you have an eye emergency or sudden change in vision, contact a medical professional immediately.

3. Eligibility, accounts, and children

To create an account you must be at least 18 years old and able to enter into a binding contract. The account holder is the adult who registers, accepts these Terms, and (where applicable) pays for the subscription.

Dichoptix is often used by or for children. Where the person doing the therapy is a child, the account must be created and managed by a parent, legal guardian, or another adult with the authority to consent on the child's behalf. That adult is responsible for the child's use of the Service and for any data shared through it. Children must not create their own accounts.

You are responsible for keeping your login credentials secure and for all activity under your account. Tell us promptly at info@dichoptix.com if you believe your account has been accessed without your permission. You agree to provide accurate information and to keep it up to date.

4. Supervisors, connect codes, and consent

The Service lets a user link with a supervisor (for example, an eye-care professional) so the supervisor can view the user's therapy metrics. Linking happens when the user enters the supervisor's connect code; the supervisor must then accept the request before any link becomes active.

Entering a connect code means you are choosing to share your (or your child's) therapy metrics with that supervisor, and it records your consent to that sharing. You can stop sharing at any time by revoking consent or removing the link in your profile; metrics are only visible to a supervisor while the link is active and consent is in place.

If you use the Service as a supervisor, you confirm that you are entitled to act in that capacity, that you will only connect with people who have agreed to share their data with you, and that you will handle the data you see lawfully and confidentially.

5. Subscriptions and billing

Parts of the Service require a paid subscription. Subscriptions can be purchased in two ways: through the Apple App Store or Google Play, where the relevant app store bills you under its own terms; or on dichoptix.com, where we bill you directly through our payment provider PayTR and the purchase is additionally governed by the Preliminary Information Form and the Distance Sales Agreement presented at checkout.

Where a subscription renews automatically, it renews for successive periods at the then-current price until you turn renewal off. You can cancel an app store subscription at any time in your app store account settings, and a web subscription on the subscription page of your account; cancellation takes effect at the end of the current billing period, and you keep access until then. We may change subscription prices and features; we will give notice of price changes as required by applicable law and, for app store purchases, by the app stores, and changes will not apply to a period you have already paid for.

For app store purchases, payments, renewals, and refunds are handled by the relevant app store under its policies, and we may not have access to your full payment details. For purchases on dichoptix.com, payment is processed by PayTR; your card details go directly from your browser to PayTR and never pass through our servers.

6. Cancellation, refunds, and right of withdrawal

Subscriptions purchased through an app store are refunded according to that store's refund policy. Where you are a consumer in Türkiye or the EU, you may also have a statutory right of withdrawal for distance contracts. By starting to use digital content or a digital service immediately, you may be asked to acknowledge that your right of withdrawal can be lost once performance has begun, to the extent permitted by law. For purchases made on dichoptix.com, withdrawal and refunds are governed by the Distance Sales Agreement you accept at checkout.

Nothing in these Terms limits any mandatory consumer-protection rights you have under the law of your country of residence, including under Turkish Law No. 6502 on Consumer Protection.

7. Acceptable use

When using the Service, you agree that you will not:

  • use the Service in any unlawful way, or for anyone other than yourself or a child or patient in your care;
  • share, resell, sublicense, or commercially exploit the Service or your account without our written permission;
  • copy, modify, reverse-engineer, decompile, or attempt to extract the source code of the game or website, except to the extent this restriction is prohibited by law;
  • interfere with, disrupt, overload, or attempt to gain unauthorised access to the Service, our systems, or other users' data;
  • upload content or data you have no right to share, or that infringes someone else's rights;
  • misrepresent your identity or your authority to act for a child or patient.

8. Your content and our intellectual property

The Service, including the games, software, designs, text, graphics, and logos, is owned by us or our licensors and is protected by intellectual-property laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the Service for its intended purpose while your account is in good standing. We reserve all rights not expressly granted.

You retain any rights you have in information you provide. You grant us the rights needed to process that information to operate and improve the Service, as described in our Privacy Policy.

9. Health, safety, and responsible use

Use the Service in a comfortable, well-lit environment and take regular breaks. Follow the session length and frequency recommended by the user's eye-care professional. Stop using the Service and consult a professional if the user experiences eye strain, headache, dizziness, nausea, or any discomfort.

A small number of people may experience discomfort or, very rarely, seizures triggered by flashing lights or patterns. If the user or anyone in their family has a history of seizures or photosensitive epilepsy, consult a doctor before use. The adult account holder is responsible for supervising a child's use, including screen time.

10. Service availability and changes

We are continually developing the Service and may add, change, suspend, or remove features. We aim to keep the Service available but do not guarantee it will be uninterrupted or error-free, and we may need to take it down for maintenance. Some features are early-stage and may not behave perfectly.

11. Disclaimers

To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will meet your requirements, achieve any therapeutic result, or be free of errors. This does not exclude any warranty or right that cannot be excluded under applicable law.

12. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of (or inability to use) the Service. Our total liability for any claim relating to the Service will not exceed the greater of the amount you paid us for the Service in the twelve months before the claim, or the minimum amount required by applicable law.

Nothing in these Terms excludes or limits our liability where it would be unlawful to do so, including for death or personal injury caused by our negligence, for fraud, or for any liability that cannot be limited under mandatory consumer law.

13. Suspension and termination

You may stop using the Service and delete your account at any time from your profile. We may suspend or terminate your access if you breach these Terms, if required by law, or if we discontinue the Service. When your account is deleted, we handle your data as described in the Privacy Policy. Sections that by their nature should survive termination (such as intellectual property, disclaimers, and limitation of liability) will continue to apply.

14. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will take reasonable steps to notify you, for example in the app or by email, and we will update the "last updated" date above. By continuing to use the Service after the changes take effect, you accept the updated Terms.

15. Governing law and disputes

These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-laws rules. The courts and enforcement offices of İstanbul, Türkiye, will have jurisdiction over disputes, except where mandatory consumer-protection law lets you bring a claim in your place of residence or before a consumer arbitration committee.
