Terms of Use
This document sets out the agreement between you and us when you use Duyarim. Instead of dense legal language we have chosen to state plainly what the product is and what it is not.
What the service is
Duyarim is a personal sound amplification app: it takes the sound around you through your device’s microphone and delivers it, amplified, to your headphones. By downloading and using the app you accept these terms.
Duyarim is not a hearing aid, a medical device or a diagnostic tool. It does not diagnose, treat or compensate for hearing loss and it does not replace a hearing aid. It is designed to help people with normal hearing follow sound more clearly in specific situations; if you have any concern about your hearing, consult a health professional.
Plans and fees
Live listening requires a paid plan. There is no free tier and no free trial period. Recordings already on your device stay accessible without a plan.
- Plans: 4.99 US dollars per week, 12.99 US dollars per month, or a one-time 49.99 US dollars for lifetime access. The store shows a price in your local currency; taxes may be added.
- In the app store versions the payment is taken through your App Store or Google Play account; in the browser version it is taken through the payment institution iyzico. In both cases we have no access to your card details and do not store them.
- The weekly and monthly plans renew automatically at the same price unless cancelled at least 24 hours before the current period ends. The lifetime plan is a one-time purchase and does not renew.
- For the renewing plans, the renewal charge is taken within the 24 hours before the current period expires.
- If we change the price, you will be notified in advance in line with store rules and asked to confirm where required.
Deleting the app from your device does not cancel a subscription; you have to use the store’s subscription settings.
Cancellation and refunds
You can cancel your subscription at any time. In the app store versions use Settings → (your name) → Subscriptions on iOS, or Play Store → Profile → Payments and subscriptions on Android; in the browser version you can cancel from the app’s Settings screen. Cancellation takes effect at the end of the current period, and you keep access for the rest of it. A lifetime purchase does not renew, so there is nothing to cancel.
How a refund works depends on where you bought. In the app store versions purchases are processed by Apple or Google, so refund requests go through that store: use reportaproblem.apple.com for Apple, or the Play Store help centre for Google. In the browser version you buy directly from us; write to destek@duyarim.com with your request, and the conditions are set out in the delivery and refund terms and the distance sales contract. Either way, if you write to us about the problem we will do what we can to help.
Responsible use
When you use Duyarim you agree that:
- You will use it personally, to improve your own hearing experience.
- Recordings stay only on your device; managing and keeping those files is up to you.
- You will not reverse engineer, modify or attempt to circumvent the security measures of the app.
Hearing safety
Listening to amplified sound through headphones can damage your hearing at excessive levels. Duyarim starts every session at 1.0× amplification, uses a limiter that cannot be disabled, and asks for separate confirmation before moving to a high gain tier. Even so, we recommend keeping the volume at the lowest level you are comfortable with and stopping immediately if it feels uncomfortable; stop is always one tap away.
The app is designed to be used with headphones only; sound is never routed to the phone speaker. When the headphones are disconnected, the output is muted immediately and the session is stopped safely.
Your recordings
The recordings you make are stored on your device and belong to you. We claim no rights over these files and have no access to them. Even after your subscription ends you can still open, play and export the recordings on your device; what ends is the ability to start a new live session.
Backing up your device and protecting your files is your responsibility. We cannot restore recordings lost to a lost device, a fault or an uninstall, because we hold no copy of them.
Warranty and availability
The app is provided “as is”. Audio latency, sound quality and stability depend on the device model, operating system version, headphone type and Bluetooth codec. No particular latency figure or compatibility with a particular device is guaranteed, and we do not promise that the app will run without interruption or error.
To the extent permitted by applicable law, we are not liable for indirect, incidental or consequential damages arising from use of the app. Our total liability will not exceed the amount you paid for the app in the twelve months before the claim arose. This limitation does not affect consumer rights that cannot be waived by contract.
Changes
If we update these terms we will change the effective date on this page and announce significant changes inside the app. Continuing to use the app after a change means you accept the new terms.
