Terms of use

§ 1 Provider, scope, contracting party

(1) These terms apply to the use of dunel: the app for the iPhone, dunel in the browser at dunel.ai/app and the related services. The provider is Julian Ivanov, dunel, Am Birkenhain 51A, 49811 Lingen (Ems), Germany, email hello@dunel.ai (“we”). Further details are in the legal notice.

(2) You always conclude the agreement on the use of dunel with us, whether you use dunel free of charge or have a subscription.

(3) You buy subscriptions in the app for the iPhone, namely from Apple (Apple Distribution International Ltd., Ireland). Apple’s terms also apply to payment, renewal, cancellation, withdrawal and refunds for that purchase.

(4) These terms do not limit any rights that Apple grants you. Your own terms and conditions do not apply.

(5) We offer subscriptions in the app from a day that we set (subscription start date). Until the subscription start date, dunel is free of charge, and § 4(1) and (2) apply. From the subscription start date, the rules on tiers, the trial and subscriptions apply (§ 4(3) to (7), §§ 5 to 9, § 10(2) and (3), § 14(4) and Annex 1). We will tell you the subscription start date at least four weeks in advance in the app and by email to the address of your account. If you create your account only after this announcement, the app tells you the date; if it has already passed, these rules apply to you from the start.

§ 2 What dunel is and does

(1) dunel is a personal assistant with artificial intelligence (AI). You can write, speak, send photos and files and bring along chats from ChatGPT and Claude. dunel saves your input word for word and with the date, answers you, adds events, tasks, deadlines and lists, reminds you of them and keeps notes on the people, companies and topics in your life.

(2) In dunel, an AI answers you, not a human. It produces answers, summaries, notes, titles and suggestions. They may be incomplete or wrong, and the AI may miss something. When dunel quotes you, it is always your own saved words: the app cuts them from what you have saved; the AI does not write them.

(3) dunel shows you what it adds, such as events, deadlines and reminders, and you can change or discard it. Reminders are an aid, not a guarantee. Whether a reminder arrives also depends on your device and its settings. Check important events and deadlines yourself.

(4) dunel does not replace advice from doctors, lawyers, tax advisers or other professionals. In an emergency, call the emergency number 112.

(5) For answers, search and storage, dunel uses services of other providers. Which ones they are and what happens to your data is set out in the privacy policy. dunel asks for your consent to processing by the AI before you first use it. Without it, you cannot use dunel. This also applies if you withdraw it later, until you consent again. If you don’t consent again within 30 days of withdrawing it, we delete your account with everything in it; this ends the contract. Until then you can export everything, and you can always delete your account.

(6) Which iPhone and iOS versions dunel supports is stated in the App Store. A photo or file that you send to dunel may be at most 50 MB. In the browser there are no voice messages, no reminders, no Face ID and no calendar.

§ 3 Account, minimum age, conclusion of the agreement

(1) You need an account for dunel. You sign in with Apple, with Google, with an email address and password or with a code sent by email.

(2) You must be at least 18 years old to use dunel.

(3) An account belongs to one person. Do not pass it on and keep your sign-in details secret. If you suspect that someone else is using your account, change your password and write to us.

(4) The user agreement is concluded when, after signing in, you tap “Agree” on the consent page and thereby accept these terms. We store which version you accepted and when. You can find the terms at any time in the app in your profile under Legal and on dunel.ai, and you can save or print them there.

§ 4 Use free of charge and tiers

(1) Until we offer subscriptions (§ 1(5)), dunel is free of charge, and you can use all functions, with the limits set out in paragraph 2.

(2) Until then, these limits apply to protect against programs and abuse:

• Bringing chats: per import, the newest 10,000 of your own messages.
• Searching the web: up to 300 searches per month. One question may need several searches. Once they are used up, dunel answers from its own knowledge until the end of the month.
• Computing: every account has a limit on how much the AI computes for that account in one day. Once it is reached, dunel tells you, keeps saving everything, and answers again from the next day.

(3) From the day on which we offer subscriptions, there are four tiers: without a subscription, trial, subscription and Plus. What each tier includes is set out with all figures in Annex 1. From that day, the tier without a subscription applies to your account until you start a trial or a subscription. The limits in paragraph 2 then no longer apply.

(4) Without a subscription you can save and view everything, be reminded of existing events, and export and delete everything. In addition, you get 5 answers per day and one web search per week. You cannot have documents read in full or bring chats without a subscription. If you send more than 5 messages on one day, dunel saves the others word for word and sorts them into your notes overnight, but does not answer them. The next day you have 5 answers again. The tier without a subscription costs nothing.

(5) Trial: 3 days with the scope of the subscription and the deviations set out in Annex 1, free of charge. After that it becomes the chosen subscription unless you cancel beforehand (§ 6(2)).

(6) Subscription: €24.99 per month or €199.99 per year.

(7) Plus: €39.99 per month, with higher quotas.

(8) We change the scope of the use free of charge (paragraphs 1, 2 and 4) only for one of the valid reasons in § 10(1) and only to the extent that this is reasonable for you. We tell you about it at least four weeks in advance in the app and by email. Export and deletion always remain possible. The transition under paragraph 3 is not such a change; it is already agreed here.

§ 5 Quotas

(1) In the trial, the subscription and Plus, dunel answers your messages, voice messages and photos up to a maximum number per day and per week: in the trial up to 150 per day and 600 per week, in the subscription up to 200 per day and 1,000 per week, in Plus up to 400 per day and 2,000 per week. These numbers serve to protect against programs and automated use.

(2) Three things have fixed quotas, whose figures are set out in Annex 1:

• Searching the web per week. A search is a message for which dunel looks something up on the web, no matter how many pages it reads for it.
• Reading documents in full per week, each up to the number of pages stated in Annex 1.
• Bringing chats per source (ChatGPT or Claude) and month, per import the newest 10,000 of your own messages.

The week begins on Monday at 0:00 in your account’s time zone, the month on the first.

(3) Once a quota is used up, dunel tells you in one sentence. Everything continues to be saved. For searches, dunel answers from its own knowledge. For a document, dunel reads the beginning, and the rest from Monday. For bringing chats, dunel tells you the date from which it works again.

(4) Once the daily maximum under paragraph 1 is reached, dunel keeps saving everything and answers again the next day. Once the weekly maximum is reached, dunel keeps saving everything and answers again from Monday, 0:00.

(5) Within the figures in paragraph 1 and Annex 1 there are no further limits.

§ 6 Trial, prices, payment

(1) All prices include statutory VAT: subscription €24.99 per month or €199.99 per year, Plus €39.99 per month. In other countries the price may differ. The price that Apple shows you before the purchase applies.

(2) The trial is an introductory offer in the App Store. It lasts 3 days and costs nothing. After that it automatically turns into the chosen subscription and costs the price shown, unless you cancel with Apple at least 24 hours before the end of the trial. Before the end of the trial, dunel reminds you in the app. Whether you get a trial is decided by Apple; there is one trial per person.

(3) Payment is made through Apple. We do not see or store any payment data, only your tier, the identifier of the purchase and the paid period.

§ 7 Term and cancellation

(1) The monthly subscription and Plus run for one month and renew by one month each time unless you cancel with Apple at least 24 hours before the end of the current period.

(2) The annual subscription runs for one year from the purchase. If you do not cancel with Apple at least 24 hours before it expires, it continues, and Apple charges the price for a further year. After this renewal you can cancel with Apple at any time. Apple refunds the amount for the unused time pro rata under its terms; if Apple does not refund it, we refund it to you ourselves.

(3) How to cancel: in your iPhone’s Settings under your Apple Account and Subscriptions, or in dunel in your profile; this opens Apple’s subscription management. An email to us does not end a subscription, because Apple bills it.

(4) Deleting your account does not cancel your subscription. dunel points this out to you before deletion and opens Apple’s subscription management.

(5) After a subscription ends, your account remains in the tier without a subscription, with everything you have saved.

(6) If you withdraw your consent to processing by the AI, you can no longer use dunel until you consent again; you can still export and delete your account. If you don’t consent again within 30 days, we delete your account (§ 2(5)). Your subscription does not end automatically as a result, neither through the withdrawal nor through this deletion (§ 7(4)). When you withdraw, dunel shows you how to cancel it with Apple. If you cancel it for this reason, you request a refund for the remaining paid time from Apple. If Apple does not refund the amount for the unused time, we refund it to you ourselves.

§ 8 Right of withdrawal

For purchases in the App Store, you have a right of withdrawal against Apple under Apple’s terms. You exercise it through Apple.

§ 9 Price changes

(1) We only increase the price of a running subscription with your consent. Apple asks you beforehand and tells you the new price. If you do not agree, your subscription ends at the end of the current period; until then the old price applies. Where Apple does not ask for consent, your running subscription keeps the old price. In addition, we tell you about an increase at least 30 days in advance in the app and by email.

(2) If we lower a price, the new price applies from the next billing period.

§ 10 Changes to the service

(1) We keep developing dunel. We only change the service for a valid reason, without additional costs for you and with clear information. Valid reasons are:

• security;
• changes in laws, case law or official requirements;
• a switch, change or discontinuation of a service that dunel uses, such as an AI system;
• technical development that improves dunel;
• protection against abuse.

(2) If a change during a running subscription affects your use more than insignificantly, we tell you clearly and comprehensibly beforehand in the app and by email to the address of your account, together with when the change takes effect and your right to cancel. You can then cancel the subscription free of charge within 30 days of our notice or, if it comes later, of the change. You cancel with Apple; we provide dunel to you until the end of the paid period, and you request a refund from Apple. If Apple does not refund the amount for the unused time, we refund it to you ourselves.

(3) The quotas of a running subscription stay the same or increase. Lower quotas only apply to new subscriptions.

§ 11 Availability

(1) We make every effort to keep dunel available at all times. We do not promise any particular availability. dunel may at times be unavailable or only partly available, for example during maintenance, in the event of disruptions on our side or at providers whose services dunel uses, or without an internet connection.

(2) Without a connection, the app on the iPhone saves what you enter and sends it as soon as there is a connection again. Answers then come later.

(3) If a very large number of people are using dunel at the same time, an answer or the bringing of chats may take longer. dunel then carries on by itself.

(4) Your statutory rights in the event of defects remain unaffected.

§ 12 Your obligations

(1) Use dunel for yourself and within the law.

(2) It is not permitted

• to save unlawful content or have dunel produce it, in particular depictions of sexual abuse of children;
• to use dunel to threaten, harass, spy on or deceive others;
• to use dunel with programs, in an automated way or for others in return for payment;
• to circumvent limits and quotas, for example with several accounts or several trials;
• to pass your account on to others.

(3) Only tell dunel about other people what you need for your everyday life, and be careful with the health and similarly personal matters of others. Only send and bring what you are allowed to upload, such as your own exports from ChatGPT and Claude.

(4) Keep the app up to date.

§ 13 Your content, data, export, deletion

(1) What you save in dunel remains yours. You grant us only the rights we need to run dunel for you: to save your content, process it, transmit it to the services named in the privacy policy, show it to you and export it for you. These rights end when you delete the content or your account; backups are then overwritten within the period stated in the privacy policy.

(2) We do not use your content for advertising, do not sell it and do not release it for training AI systems.

(3) You can export everything at any time, original files included, in every tier, including without a subscription and after a subscription has ended.

(4) You can delete chats (except the main chat), lists and notes in the app at any time, as well as your whole account. You delete a note by asking dunel in the chat. We delete individual messages and the main chat for you if you write to us at hello@dunel.ai. What briefly remains after that is set out in the privacy policy: backups for up to 8 days, logs for abuse protection at the AI provider for up to 30 days and a deletion record without content.

(5) How we protect and process your data is set out in the privacy policy.

(6) We back up your texts and entries daily. A backup restores a state from up to 24 hours earlier. Your original files, that is voice recordings, photos and documents, are not included in these backups. As a rule, they also remain on the iPhone from which you sent them, as long as dunel is installed there. For files that matter to you, we recommend also using the export.

§ 14 Suspension and termination by us

(1) If you seriously breach § 12, we may suspend your account in whole or in part. Beforehand, we tell you the reason and give you the opportunity to respond, except in case of imminent danger or where a law prohibits it. We give reasons for every suspension.

(2) During a suspension you can still export, unless a legal reason prevents it.

(3) As long as you do not have a paid subscription, we may terminate the user agreement with four weeks’ notice. We tell you in the app and by email. Until the end you can export everything.

(4) During a paid period we only terminate for good cause. If we terminate without you having given cause, we provide dunel to you until the end of the paid period; if that is not possible for good cause, we show you how to get a refund from Apple, and if Apple does not refund the amount for the unused time, we refund it to you ourselves. In any case you cancel your subscription yourself with Apple, because we cannot end it; we tell you in good time in the app and by email.

(5) We do not look through your content on our own initiative and do not check it automatically for breaches. We act only on a notice sent to hello@dunel.ai, and a human always decides on a suspension. The AI may decline to answer a message; the message stays saved anyway.

§ 15 Warranty and updates

(1) The statutory rights in the event of defects in digital products apply.

(2) We provide the updates needed for dunel to remain in conformity with the agreement, including security updates, and inform you about them in the App Store and in the app. If you do not install an update within a reasonable time, we are not liable for a defect that is solely due to this, provided we informed you about the update and the consequences.

§ 16 Liability

(1) We are liable without limitation

• for damage resulting from injury to life, body or health based on an intentional or negligent breach of duty by us, our legal representatives or vicarious agents;
• for all other damage based on an intentional or grossly negligent breach of duty by us, our legal representatives or vicarious agents;
• in the event of fraudulent concealment of a defect and to the extent of a guarantee we have given;
• under the German Product Liability Act (Produkthaftungsgesetz).

(2) In the event of simple negligence by us, our legal representatives or vicarious agents, we are only liable if an essential contractual obligation is breached, that is, an obligation whose fulfilment makes the proper performance of the agreement possible in the first place and on whose observance you may regularly rely. In that case, liability is limited to the damage that was foreseeable at the time the agreement was concluded and typical for this agreement.

(3) Otherwise we are not liable. This also applies to our legal representatives and vicarious agents.

(4) Paragraphs 1 to 3 also apply to damage arising from answers, notes, entries or reminders of the AI. What the AI does and does not do is described in § 2(2) to (4).

(5) Claims under the General Data Protection Regulation remain unaffected.

§ 17 End of the agreement, deleting your account

(1) You can end the user agreement at any time by deleting your account in the app.

(2) Export beforehand whatever you want to keep. After deletion we cannot restore anything.

(3) You cancel a subscription with Apple; deletion alone does not end it (§ 7(4)).

§ 18 Changes to these terms

(1) We only change these terms with your consent. We announce a new version to you at least four weeks in advance in the app and by email, together with the changes. From the day stated, the app shows you the new version, and you confirm it actively with “Agree”. We store which version you confirmed and when.

(2) Until you agree to the new version, you cannot use dunel; you can always export and delete your account. If you do not agree, you can end the agreement at any time by deleting your account (§ 17). For paid time in which you do not use dunel for this reason, you request a refund from Apple; if Apple does not refund the amount, we refund it to you ourselves. You cancel your subscription yourself with Apple, because we cannot end it; we tell you in good time in the app.

§ 19 Dispute resolution, law, language, contact

(1) We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board.

(2) German law applies. If you are a consumer and your habitual residence is in another country, you keep the protection of the mandatory provisions of that country.

(3) These terms are available in German, English, Spanish, French, Portuguese and Italian. The German version is authoritative.

(4) Send questions, notices of unlawful content and everything else to hello@dunel.ai.

Annex 1: Overview of the service

Applies from the day on which we offer subscriptions in the app (§ 1(5)).

The maximum numbers of answers in the trial, the subscription and Plus serve to protect against programs and automated use (§ 5(1)). At every limit, dunel keeps saving everything. Once the daily number is reached, dunel answers again the next day; once the weekly number is reached, from Monday, 0:00. Within these numbers there are no further limits (§ 5(5)).

Annex 2: Addendum for the app from the App Store

For the app from the App Store, the following also applies:

1. These terms apply between you and us, not between you and Apple. We, not Apple, are responsible for dunel and its content.
2. You may use the app on Apple devices that you own or control, within the usage rules of the App Store.
3. We, not Apple, provide maintenance and support.
4. As between us and Apple: if the app fails to conform to a statutory warranty, you can notify Apple, and Apple will refund the purchase price under its rules; beyond that, Apple is not responsible for any warranty. Your statutory rights against Apple as the seller remain unaffected.
5. As between us and Apple: we, not Apple, are responsible for claims relating to the app, for example from product liability or consumer protection. Your statutory rights against Apple as the seller remain unaffected.
6. If someone claims that the app infringes their rights, we, not Apple, will deal with it.
7. Do not use the app if you live in a country against which the USA has imposed an embargo, or if you are on a list of prohibited persons of the USA.
8. When using the app, comply with the terms of your mobile or internet provider.
9. Name and address for questions and complaints: as in § 1(1).
10. Apple and its subsidiaries are third-party beneficiaries of these terms and can enforce them against you.
