These Terms of Use (the “Terms”) govern the use of the app “Lungo” (the “App”) on iOS and Android, including its free features and paid additional features (“Lungo Plus”). The provider of the App and your contractual partner for its use is Luke Bickenbach (“we”, “us”). Purchases through a store are also subject to the allocation of roles in section 7.

Before completing onboarding, you can read and save these Terms. You accept them by an express confirmation; simply continuing to use the App does not replace this consent. The current version is available under Settings → Terms of use. Existing contracts remain subject to the agreed version unless it is validly changed under section 17.

Important: Lungo is not a medical device and does not replace medical advice (see section 4).

1. Scope

These Terms apply to the use of the App and its connected services (e.g. cloud synchronisation of your progress) and to the purchase of Lungo Plus. Deviating or supplementary terms of the user do not apply.

For obtaining the App and making purchases via the Apple App Store or Google Play, the terms of the respective store operator apply in addition (see sections 18 and 19).

"Consumer" within the meaning of these Terms is any natural person who uses the App for purposes that are predominantly outside their trade, business or profession.

2. Conclusion of contract

By completing onboarding in the App, a free-of-charge usage agreement covering the free features of the App is concluded between you and us. There is no entitlement to the conclusion of this agreement.

A paid purchase of Lungo Plus occurs only once you submit a binding purchase confirmation in the Apple App Store or Google Play and the store confirms the purchase. Selecting an offer in the App alone does not trigger payment. The contractual party identified at checkout and the additional store terms apply (see section 7).

The contract language is German or English, according to your chosen App language. You can save and print the Terms, including the withdrawal instructions and model form, at trylungo.com/terms/.

3. Features of the App

Lungo is a companion for quitting smoking or vaping. The free core features include in particular:

recording your quit date and your previous consumption
daily check-ins, streaks and progress displays
logging cravings, including the breathing exercise
statistics (e.g. money saved, smoke-free days)
the playful reward system around the Smoke Buddy (XP, levels, coins, items)
local reminders and the cloud backup of your progress

Lungo Plus includes additional craving insights about triggers, times and moods, situational Coach strategies and exclusive cosmetic content for Lungo. The specific description and any requirements of individual features are displayed before purchase and govern that purchase. New App versions do not automatically change the agreed features; section 12 applies.

4. Not a medical device, no medical advice

Lungo is not a medical device or medicinal product and does not provide medical, psychological or therapeutic advice, diagnosis or treatment. The contents of the App (e.g. milestones, statistics, learning content, breathing exercise and Coach strategies) serve general information and motivation only.

Calculations such as money saved, cigarettes not smoked or health-related milestones are approximations based on your entries and general average values. We do not guarantee their accuracy in individual cases.

If you experience health problems, severe withdrawal symptoms or have questions about quitting, please consult a doctor. Whether you succeed in quitting smoking or vaping depends on many factors beyond our control; we do not owe any particular outcome.

5. Requirements and minimum age

You need a compatible iOS or Android device and, for the cloud backup, an internet connection. You bear the costs of your data connection.

The App is intended exclusively for adults who want to quit smoking or vaping. You must be at least 18 years old to use Lungo. People under the age of 18 may not use the App, even with the consent of a parent or guardian.

6. Account and backup

If you use Lungo without an account, your profile and progress data remains on your device. After onboarding, only a random pseudonymous Firebase installation ID is created to document your consent choices; this does not enable cloud backup.

Cloud backup is voluntary and switched off by default. If you expressly select it and sign in with Apple or Google, your progress is backed up in the cloud under your pseudonymous Firebase account and can be restored. Without cloud backup, local data may be irretrievably lost, for example after deleting data, switching devices or resetting the device.

Keep your login credentials secret and do not pass them on to third parties.
Inform us if you suspect unauthorised use of your account.
Only one account per person is permitted; information provided during registration must be accurate.

7. Lungo Plus: subscriptions and one-time purchase

a) Offers and prices

Lungo Plus unlocks additional features and is offered as a monthly subscription, an annual subscription or a one-time purchase ("Lifetime"). The specific prices (including VAT), terms and any free trial periods are shown to you before purchase in the order dialog of the respective store; the conditions stated there are decisive.

b) Automatic renewal and cancellation of subscriptions

Subscriptions renew automatically for the period specified at purchase unless you stop renewal in time through your store account. The cancellation deadlines shown at checkout and in the relevant store subscription settings apply. For Apple, you should in particular cancel a free or discounted trial at least 24 hours before it ends; for Google Play, cancel before the next renewal. On iOS, manage subscriptions under Settings → [your name] → Subscriptions; on Android, use Payments and subscriptions in Google Play. After ordinary cancellation, Plus remains available until the end of the paid period; Plus access then ends while free features remain available. During trials, access may end on cancellation under the displayed store terms. Deleting the App or your Lungo account does not cancel a subscription. Statutory withdrawal, warranty and extraordinary termination rights can be exercised independently of ordinary subscription management.

c) Free trial

Where a free trial is offered, its duration, subsequent billing period and subsequent price are displayed before purchase. It converts automatically into a paid subscription unless cancelled within the deadlines in section 7 b). Trial eligibility is governed by the offer conditions displayed by the store.

d) Lifetime purchase

“Lifetime” means a one-time payment to unlock the agreed Lungo Plus features for the period during which the App is provided, without a subscription or automatic renewal. It does not promise operation for your personal lifetime or an additional fixed minimum period. We may not arbitrarily end a service we owe; sections 12, 13 and 16 and your mandatory statutory rights also apply to Lifetime. If the App is discontinued, entitlement to a refund and its amount are determined by the statutory rights applicable to the individual case, including rights relating to services not provided or provided defectively. We provide no additional voluntary money-back guarantee and impose no flat depreciation schedule on the purchase price.

e) Processing via the stores

Purchase and payment take place exclusively through the relevant store. The seller or contractual party for the purchase is identified in the checkout and receipt. For purchases through Apple Distribution International Ltd., Apple is the merchant of record under its store terms; we remain the provider and licensor of the App. The relevant store terms govern processing. Refunds are generally processed through the store payment system used for the purchase. Apple requests can be submitted at reportaproblem.apple.com; for Google Play, use its refund function. Contact hello@trylungo.com with questions, complaints or claims. We assess claims against us ourselves; referring to the store does not limit those claims.

f) Price changes

Price changes never apply retroactively. For ongoing subscriptions, price changes only take effect under the mechanisms of the respective store, which informs you in advance and – where provided – allows you to consent or cancel.

8. Right of withdrawal for consumers

a) Withdrawal instructions

As a consumer, you generally have 14 days from the day a distance contract with us is concluded to withdraw without giving reasons. For a purchase contract with a store operator, its withdrawal information also applies; more favourable rights remain unaffected.

To exercise withdrawal against us, inform us (Luke Bickenbach, Dresdner Straße 19/14, 1200 Vienna, Austria, hello@trylungo.com, phone: +49 157 56051113) of your decision by an unequivocal statement, such as an email or letter. You may use the model form below, but it is not mandatory. Sending the statement before the 14-day period expires is sufficient. The purchase date, product and store order number help identify the transaction but are not prerequisites for valid withdrawal.

b) Effects of withdrawal

If you validly withdraw from a contract with us, we reimburse all payments received from you without undue delay and no later than 14 days after receiving your withdrawal. We use the same payment method as the original transaction unless expressly agreed otherwise at no cost to you. There are no refund fees. For store payments, the refund is processed through its payment system; your claims against the responsible contractual party remain unaffected. The Plus entitlement covered by the withdrawal ends when the transaction is reversed. Ordinary subscription cancellation is different from withdrawal.

For a service, a proportionate amount for services already performed is payable only if you expressly requested performance before the withdrawal period ended and all statutory information requirements were fulfilled. Without those conditions, we do not request such compensation.

c) Conditions for early expiry

For paid digital content not supplied on a tangible medium, the right expires only if delivery has begun, you previously expressly consented to delivery within the withdrawal period and acknowledged the resulting loss of withdrawal rights, and the legally required contract confirmation including those declarations was provided on a durable medium. For services, early expiry generally occurs only once the service has been fully performed, subject to the required express consent and acknowledgement. The legal classification of the actual purchased service or content determines the applicable rules. Immediate Plus activation or acceptance of these Terms alone does not waive withdrawal. Where the statutory conditions are not met, the right remains in place.

d) Model withdrawal form

If you wish to withdraw, you may complete this form and send it to us. For a purchase contract with a store operator, address the declaration to the contact identified in its withdrawal instructions. Store refund functions are described in section 7 e).

To: Luke Bickenbach, Dresdner Straße 19/14, 1200 Vienna, Austria, hello@trylungo.com
I/We (*) hereby give notice that I/We (*) withdraw from my/our (*) contract for the supply of the following digital content or the performance of the following service: __________
Ordered on (*) / received on (*): __________
Name of consumer(s): __________
Address of consumer(s): __________
Signature of consumer(s) (only if this form is notified on paper): __________
Date: __________
(*) Delete as appropriate.

9. Virtual content (XP, coins, items)

XP, levels, streaks, coins, items, trophies and the Smoke Buddy are game features of the App. They have no monetary value, cannot be paid out, transferred, exchanged or sold, and do not create ownership – only a right of use within the App.

Virtual content may lapse if you delete your data or your account or if the usage relationship ends. We may adjust the game system (e.g. balancing, availability of individual items) as part of the further development of the App; sections 12 and 13 remain unaffected.

10. Licence

We grant you a simple, non-exclusive, non-transferable and non-sublicensable right to use the App on your devices for private, non-commercial purposes. When using Apple devices, the restriction in section 18 additionally applies.

All contents of the App (in particular graphics, pixel sprites, the Smoke Buddy, texts and software) are protected by copyright. Reproduction, modification or distribution outside the App requires our prior consent. Mandatory statutory rights (e.g. to create backup copies or to decompile within the statutory limits) remain unaffected.

Sharing your own progress cards via the App share feature is expressly permitted.

11. Prohibited use

When using the App, you are in particular prohibited from:

manipulating or circumventing security, purchase or unlocking mechanisms
automated access (bots, scraping) to the App or its underlying services
interfering with the server infrastructure or the cloud services or disrupting their operation
reselling access or Plus unlocks or providing them to third parties for payment
using the App for unlawful purposes

In the event of serious or repeated violations, we may suspend your account or terminate the usage relationship in accordance with section 16.

12. Availability, updates and changes to the App

We strive for high availability of the App and the cloud services but do not owe uninterrupted availability. Maintenance, updates and disruptions at third parties (e.g. stores, cloud providers, network operators) may temporarily restrict use.

We continuously develop the App and may change, add or discontinue features if there is a valid reason for doing so (e.g. technical development, security, changes in the law or – for free features – economic reasons) and the change is reasonable for you, weighing the interests of both sides.

For digital services or content supplied continuously, changes beyond required updates are permitted only subject to statutory conditions, including no additional cost and clear, understandable information. If a change impairs your access or use more than minimally, we inform you reasonably in advance on a durable medium, such as email or a notice addressed to you that can be stored unchanged. It describes the nature and timing of the change and your right to terminate without charge. You may exercise that right within 30 days of the change; if the required information arrives later, the period starts on receipt. There is no such right if we offer you the unchanged service, still in conformity with the contract, at no additional cost. Statutory rules, in particular sections 24 to 27 of the Austrian VGG, govern unwinding the contract. A mere reference to an editable App page does not replace the required durable notice.

Should the App be discontinued entirely, we will announce this in the App with reasonable notice. Section 16 applies accordingly.

13. Warranty

Statutory warranty rights for digital content and services apply to Lungo Plus, in Austria particularly under the Consumer Warranty Act (VGG). We provide the updates required to maintain conformity with the contract. For continuous supply, this covers the entire period of supply owed; for one-off supply, the period reasonably expected given the nature and purpose of the service or content. The agreed form of supply is decisive, not merely whether payment is one-time or recurring. This also applies to Lifetime.

The statutory rules apply to the free features of the App; we do not assume any guarantees of quality beyond that.

14. Liability

These Terms do not exclude or limit statutory liability for personal injury or for other damage caused intentionally or through gross negligence. The statutory requirements for a claim for damages remain unchanged. Other mandatory liability provisions, particularly product liability law, remain unaffected.

In cases of slight negligence, we are only liable for the breach of essential contractual obligations, i.e. obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely; in this case, liability is limited to the foreseeable damage typical for the contract. Otherwise, liability for slight negligence is excluded.

Without cloud backup, local profile and progress data may be lost when data is deleted, a device is changed or reset (see section 6). We are not liable for such loss insofar as we are not at fault; the preceding liability rules and mandatory statutory rights remain unaffected.

15. Privacy

Information about which personal data Lungo processes can be found in our privacy policy. It is available at any time in the App under Settings and does not form part of these Terms.

16. Term and termination

You can end the free usage relationship at any time by deleting your data or your account in the settings or by uninstalling the App. Note: you must additionally cancel ongoing subscriptions via the respective store (see section 7); uninstalling alone does not cancel a subscription.

We may terminate free use with at least four weeks’ notice in the App. This does not end existing rights to paid services. If we discontinue the App or end paid supply early, termination and refunds are governed by statutory requirements. For subscriptions, this includes refunding prepaid periods no longer provided insofar as required by law. Lifetime is subject to the statutory rights in section 7 d); no fictitious subscription period or flat time-based reduction is agreed for it. Technical processing through a store does not extend statutory refund deadlines.

The right to extraordinary termination for good cause remains unaffected. Good cause exists for us in particular in the event of serious violations of section 11 or repeated violations despite a warning; a prior warning is given where reasonable for us.

17. Changes to these Terms

We may amend these Terms if there is a valid reason for doing so, such as changes in the law or case law, new or changed features of the App, or the closing of regulatory gaps, and the amendment does not unreasonably disadvantage you. The main contractual obligations are not changed by this means.

We inform you of proposed changes and make the new text available. Material changes to an existing contract take effect only with your active consent. Without consent, its previous version continues to apply; automatic subscription renewal does not constitute consent. A separate new purchase may be made under the new terms expressly accepted at that time. Any termination of free use is governed by section 16; paid rights remain in place.

18. Additional terms for the Apple App Store

If you obtained the App via the Apple App Store, the following additionally applies: these Terms are concluded between you and us, not between you and Apple. Apple is not responsible for the App or its content and has no obligation to provide maintenance or support for the App.

The licence is limited to use of the App on Apple-branded devices that you own or control, as permitted by the App Store Usage Rules.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you, where applicable. Apple has no other warranty obligation; all other claims are directed to us.
We, not Apple, are responsible for addressing any claims relating to the App – for example product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection law.
In the event of any third-party claim that the App infringes intellectual property rights, we, not Apple, are responsible for the investigation, defence, settlement and discharge of such claim.
You represent and warrant that 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 that 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 has the right to enforce them against you.

Direct questions, support requests and complaints about the App to hello@trylungo.com or the postal address above.

19. Additional terms for Google Play

If you obtained the App via Google Play, the Google Play Terms of Service additionally apply. For purchases and refunds via Google Play, the Google Play policies also apply insofar as they deviate from these Terms in your favour.

20. Consumer dispute resolution

We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board. We strive to resolve any disagreements directly with you – just write to the contact address above.

21. Governing law and jurisdiction

Austrian law applies, excluding the UN Convention on Contracts for the International Sale of Goods and the conflict-of-law rules of private international law. If you are a consumer with habitual residence in the EU or EEA, you additionally retain the protection of the mandatory consumer protection provisions of the state in which you have your habitual residence.

The statutory places of jurisdiction apply to consumers. If you are a business, the exclusive place of jurisdiction is Vienna, Austria.

22. Final provisions

Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions remains unaffected. The statutory provisions take the place of the invalid provision.
