Description of the App

QYSH is a motivational and tracking tool that helps you monitor, plan and reduce your tobacco/nicotine consumption. It offers countdown timers, statistics, reduction plans, notifications, home screen and smartwatch widgets, and an optional Bluetooth connection to compatible devices. The app's core features can be used free of charge; certain features ("QYSH Pro") require a paid subscription or one-time purchase, as described under "Subscription and Pricing" below. The app is provided for personal, non-commercial use only.

Age Requirement

The app deals with tobacco and nicotine consumption and is intended exclusively for adults. You must be at least 18 years old to download, install, or use the app. By using the app, you confirm that you meet this age requirement.

License

Subject to your compliance with these Terms, Vladimir Cabacov (mircov) grants you a personal, limited, non-exclusive, non-transferable, and revocable license to install and use the app on devices you own or control, exclusively for your own personal, non-commercial purposes. All rights, title, and interest in and to the app, including all intellectual property rights, remain with Vladimir Cabacov (mircov) or its licensors.

Your Obligations

• Use the app only for lawful purposes and in accordance with these Terms.
• Do not reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the app, except to the extent permitted by mandatory law.
• Do not modify, copy, distribute, sell, sublicense, or create derivative works based on the app.
• Do not use the app in any way that could damage, disable, overburden, or impair the app or interfere with any other party's use of it.
• You are solely responsible for the device on which you install the app and for any third-party hardware you connect to it.

Subscription and Pricing

The app's core features are available free of charge. Certain additional features, referred to as "QYSH Pro" (in particular the Bluetooth connection to compatible devices and detailed statistics), require a paid subscription or a one-time lifetime purchase. You can choose between a monthly subscription, an annual subscription, or a one-time lifetime purchase that grants permanent access to QYSH Pro. All purchases are billed and processed exclusively through the Apple App Store or Google Play, and their respective terms of sale, payment, cancellation, and refund policies apply. Monthly and annual subscriptions renew automatically for the same period unless cancelled in accordance with the respective store's policies before the end of the current billing period. The lifetime option is a one-time payment that does not renew or expire. The term "lifetime" refers to the lifetime of the app as an actively offered product, not to an unlimited guarantee by Vladimir Cabacov (mircov); the consequences of a permanent discontinuation of the app or an insolvency are governed by the "Availability and Changes" section below. Refunds are handled solely by Apple or Google in accordance with their own policies; Vladimir Cabacov (mircov) has no access to your payment data and cannot process refunds directly. Current prices are displayed in the app and in the respective app store before purchase and may vary by region.

Monthly and annual subscriptions may be offered with an introductory free trial of 7 days. If you do not cancel before the trial period ends, the subscription automatically converts into a paid subscription and the applicable price is charged to your Apple ID or Google Play account. You can cancel at any time during the trial in your Apple ID or Google Play account settings to avoid being charged. Trial eligibility and the exact offer terms are subject to Apple's and Google's respective policies.

The purchase and billing of subscriptions is additionally governed by the respective store's own terms:

Apple https://www.apple.com/legal/internet-services/itunes/us/terms.html

Google https://play.google.com/intl/en_us/about/play-terms/index.html

Right of Withdrawal

Your purchase of a subscription or lifetime access is made through and billed by Apple (Apple Distribution International Ltd.) or Google (Google Commerce Ltd. / Google Ireland Ltd.), who act as the seller of record for the transaction in most jurisdictions. Any statutory right of withdrawal for online purchases of digital content, and its exclusion or early expiry once performance has begun, is therefore governed by Apple's and Google's own terms of sale referenced above, not by Vladimir Cabacov (mircov).

Third-Party Devices and Trademarks

The app offers an optional Bluetooth connection to compatible IQOS devices. You are responsible for ensuring your device is compatible and used in accordance with the manufacturer's instructions. The Bluetooth connection relies on an unofficial interface that is not supported by the manufacturer. Establishing and maintaining the connection, as well as automatic reconnection, depend on the behaviour of the respective device (including firmware, battery level and power-saving behaviour) and cannot be guaranteed. Occasional disconnections are technically inherent; in rare cases the device must be turned off and on again to restore the connection. The app's core features do not depend on an active device connection.

IQOS is a trademark belonging to Philip Morris Products S.A. Vladimir Cabacov (mircov) is not affiliated with, representative for, or agents of, Philip Morris Products S.A. and Vladimir Cabacov (mircov)'s products are not endorsed, reviewed, tested, or supported by Philip Morris Products S.A. All liability for such products remains with Vladimir Cabacov (mircov) as product manufacturer.

No Medical Advice; Disclaimer

The QYSH app is a motivational and tracking tool designed to support personal habit building. The app does not provide medical, therapeutic, or psychological advice, diagnosis, or treatment. It is not a substitute for professional medical advice or addiction counselling. Use of the app is at your own risk.

The app is provided "as is" and "as available", without warranties of any kind, whether express or implied, to the extent permitted by applicable law.

Limitation of Liability

To the extent permitted by law, Vladimir Cabacov (mircov) shall only be liable for damages arising from intent or gross negligence, or for the negligent breach of a material contractual obligation (cardinal obligation), or in cases of injury to life, body, or health. Liability for the loss of data is limited to the typical, foreseeable damage that would have occurred even if you had regularly and adequately backed up your data. Mandatory statutory liability, in particular under product liability law, remains unaffected.

Availability and Changes

Vladimir Cabacov (mircov) strives to keep the app available and functional but does not guarantee uninterrupted or error-free operation. Features may be added, changed, or removed at any time, in particular to reflect technical developments or changes to third-party device compatibility. Use of the app requires the minimum technical requirements specified in the Apple App Store or Google Play at the time of download or purchase (in particular, operating system version and device compatibility). These minimum requirements may change with future app updates; older devices or operating system versions may then no longer be supported.

The following applies in addition for subscriptions and the lifetime purchase: because access is unlocked exclusively on your device based on the purchase confirmation from Apple (StoreKit) or Google (Google Play Billing), and Vladimir Cabacov (mircov) does not operate its own license or activation server for this purpose, an already installed version of the app generally remains usable on your device even if Vladimir Cabacov (mircov) ceases business operations, becomes insolvent, or otherwise ceases to exist. However, this does not guarantee continued compatibility with future operating system versions, new devices, or third-party services, nor does it guarantee the continued provision of updates. If the app is permanently discontinued, removed from the Apple App Store or Google Play, or if Vladimir Cabacov (mircov) ceases business operations (including insolvency), this does not give rise to any claim for a refund, replacement, or damages against Vladimir Cabacov (mircov); any claims relating to payments already made are, in this case, governed exclusively by Apple's or Google's refund policies (see the "Subscription and Pricing" section). To the extent economically and organizationally feasible, Vladimir Cabacov (mircov) will inform users with active lifetime access of a planned, permanent discontinuation of the app with reasonable advance notice.

Apple App Store – Additional Terms

If you obtained the app through the Apple App Store, the following additional provisions apply:

• These Terms are concluded between you and Vladimir Cabacov (mircov) only, not with Apple Inc. ("Apple"). Vladimir Cabacov (mircov), not Apple, is solely responsible for the app and its content.
• The license granted to you is limited to a non-transferable license to use the app on Apple-branded devices that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions (except that the app may also be accessed and used by other accounts associated with you via Family Sharing or volume purchasing).
• Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the app.
• In the event of any failure of the app to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the app; any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are the responsibility of Vladimir Cabacov (mircov).
• Vladimir Cabacov (mircov), not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession and/or use of the app, including but not limited to: (i) product liability claims; (ii) claims that the app fails to conform to applicable legal or regulatory requirements; and (iii) claims arising under consumer protection or similar legislation.
• In the event of any third-party claim that the app or your possession and use of the app infringes that third party's intellectual property rights, Vladimir Cabacov (mircov), not Apple, is solely responsible for the investigation, defence, settlement, and discharge of such claim.
• You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof. You must also comply with any applicable third-party terms of agreement when using the app.

Termination

You may stop using the app and delete it from your device at any time. Vladimir Cabacov (mircov) reserves the right to restrict or terminate access to the app, in whole or in part, if you materially breach these Terms.

Changes to these Terms

These Terms may be updated from time to time to reflect changes to the app or legal requirements. The current version is always available on this page. In the event of significant changes, you will be notified within the app and asked to review and accept the updated Terms before you continue using the app.

Governing Law and Jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of the country in which you have your habitual residence remain unaffected. To the extent legally permissible, the place of jurisdiction is Düsseldorf, Germany.

Severability

Should any provision of these Terms be or become invalid or unenforceable, the validity of the remaining provisions shall not be affected.
