Terms and Conditions
1. Provider and scope
- (1)
These terms apply to the use of the “UmbraLux” app for iOS and Android and to everything you buy in the app. They also apply to the Meisterbuch if you order it through our website umbralux.app; for the purchase contract, paragraph 4 then applies.
- (2)
The provider is Adrian Schmidt, Adalbert-Stifter-Straße 4, 82494 Krün, Germany, email: sternenschmied96@gmail.com (“we” or “us”). You conclude the contract for using the app with us.
- (3)
You make purchases in the app through the Apple App Store or Google Play. The respective store is the seller, and its terms apply in addition.
- (4)
If you order the Meisterbuch through our website, you buy it from us. Payment goes through our checkout on principium.one with the payment service Stripe; you receive the invoice by email. These terms apply to the creation of your book in the app.
2. What UmbraLux is
- (1)
UmbraLux is an app for self-reflection. At its heart is Verus, an AI companion who knows the profile calculated from your birth data and talks with you about it. The profile draws on astrology, Human Design, BaZi and numerology, among others. In addition, there is a library, personal reports and the printed Meisterbuch.
- (2)
You can use part of this free of charge. Premium (as a monthly or yearly subscription, or as a one-time “Lifetime” purchase) and single purchases cost money: reports, the Meisterbuch and the Meisterbuch audiobook. You can see what each includes before you buy, in the app and, for the Meisterbuch, on our website.
3. No advice, no therapy
- (1)
The content of UmbraLux, including Verus’ replies, is meant for self-reflection, inspiration and entertainment. It is based on the interpretations of the respective teachings. It is not a prediction and not a scientifically proven statement about you.
- (2)
Verus is not therapy. UmbraLux does not replace medical, psychotherapeutic, legal or financial advice. Do not make important decisions, for example about your health, your relationships or your money, on this basis alone.
- (3)
If you are not doing well or are thinking about harming yourself, please reach out right away to people who can help: in Germany, the Telefonseelsorge on 0800 111 0 111 or 0800 111 0 222, free of charge and around the clock, or online at telefonseelsorge.de (in German). In Austria, you can reach the Telefonseelsorge on 142, in Switzerland Die Dargebotene Hand on 143; in other countries, please contact a local crisis line. In an emergency, call 112 or your local emergency number.
4. AI content
- (1)
Verus is an AI system. His replies, the titles and summaries of your chats, your reports and the texts of the Meisterbuch are generated by language models from Mistral AI. OpenAI converts voice messages into text; OpenAI also generates read-aloud replies, the audio versions of your reports and the Meisterbuch audiobook.
- (2)
AI texts may contain errors, be incomplete or not fit you. We do not check them individually; the exception is the Meisterbuch, which we review before printing. We do not warrant that AI content is correct and complete. Your statutory rights in the event of defects remain unaffected.
5. Your account
- (1)
You need an account to use UmbraLux. You sign in with Apple, Google or your phone number. The contract for using the app is concluded when you register and agree to these terms.
- (2)
You must be at least 16 years old.
- (3)
Please provide accurate information, especially your birth data, because all calculations are based on it.
- (4)
Your account is personal and not transferable. Protect your access from others.
- (5)
We may automatically delete accounts whose setup has not been completed after 14 days.
6. Free use, Premium and fair use
- (1)
Free of charge, you can send Verus a limited number of messages per day, currently 20. The app shows you the current number.
- (2)
Premium lifts this limit within the bounds of fair use (paragraph 3), unlocks, among other things, the entire library and read-aloud replies, and includes report credits (section 8). You can see the exact scope in the app before you buy.
- (3)
Fair use: to protect against automated or abusive use, Premium, too, allows at most 300 messages with Verus per day. Every reply from Verus counts, including his opening of a new chat.
- (4)
Some other features, such as the audio versions in the library, also have daily limits; the app shows them to you.
- (5)
The daily counters reset every day at 0:00 UTC, which is 1:00 in Germany, or 2:00 during summer time.
- (6)
After you set up your profile, we give you 7 days of Premium once. The period ends by itself; no subscription is created and there are no costs. Report credits are not included.
7. Purchases and subscriptions
- (1)
Premium is available as a monthly or yearly subscription and as a one-time “Lifetime” purchase. You buy reports and the Meisterbuch audiobook individually in the app, and the printed Meisterbuch on our website (section 1(4)).
- (2)
Purchases in the app are handled by the Apple App Store or Google Play; you pay through your account there. The price the store shows you before you buy applies.
- (3)
The term, renewal and cancellation of a subscription are governed by your store’s terms. A subscription renews automatically for the chosen period unless you cancel it in time in your store’s subscription settings: with Apple at least 24 hours before it ends, with Google Play before the renewal date. After you cancel, Premium stays active until the end of the paid period.
- (4)
If the store offers you a free trial when you subscribe, it automatically turns into the paid subscription unless you cancel before it ends.
- (5)
“Lifetime” is a one-time payment without renewal. With it, Premium stays active for as long as we offer UmbraLux.
- (6)
If the store refunds a purchase, whatever the purchase unlocked is removed, for example Lifetime Premium or a report whose creation has not started yet.
8. Report credits
- (1)
Paid Premium includes credits you can use to unlock reports:
- with the monthly subscription, 1 foundation credit when you subscribe and with every monthly renewal,
- with the yearly subscription, 1 foundation credit and 1 deep-dive credit when you subscribe; the yearly renewal brings no further credits,
- with the purchase of Lifetime, 2 foundation credits and 2 deep-dive credits once.
- (2)
The 7 days of Premium we give you (section 6(6)) and Premium from the referral programme (section 12) do not come with credits.
- (3)
The app shows you which reports you can unlock with which credit. The Master Profile cannot be unlocked with credits.
- (4)
Credits have no cash value. They cannot be paid out or transferred, and they expire when you delete your account.
9. Reports
- (1)
Reports are single purchases and are not included in Premium. You can also unlock them with credits (section 8).
- (2)
After your purchase, an AI creates your report from your profile. This usually takes 5 to 10 minutes; you can close the app in the meantime.
- (3)
If the creation stops, you can restart it in the app. If your report is not ready after 20 minutes or its creation fails for good, contact us: we will create your report again.
- (4)
For each report, you can have an audio version created up to three times, for example with a different voice.
10. Meisterbuch and audiobook
- (1)
The Meisterbuch is available printed, as an A5 hardcover book of about 200 pages, and digitally, as a PDF and to read in the app, optionally with the audiobook. It is available in German only. We create it with the help of AI from your profile. For this, you need an UmbraLux account with complete birth data (date, time and place).
- (2)
You order the Meisterbuch on our website. We then match your order to your account in the app.
- (3)
Before your book goes to print, we review it and check your details, the dedication and the delivery address. After that, we release it (the “release”). From the release onwards, you can read it in the app and download it as a PDF.
- (4)
You can cancel your order until the release; an email to us is enough. We then stop the creation and arrange the refund of the purchase price. If you bought the Meisterbuch in the app (possible in app versions before 2.1), we also arrange the refund ourselves for Google Play; with Apple, only Apple can issue refunds: you request the refund there at reportaproblem.apple.com, and we support you in doing so.
- (5)
Printing and shipping are handled by our printing partner, who sends the book directly to you; shipping is included in the price. We deliver within the European Union. From the release, it usually takes 2 to 3 weeks until the book reaches you.
- (6)
The printed Meisterbuch and the digital edition with audiobook include the audiobook: it is created after the release in a standard voice and then appears in the app. For the digital edition without audiobook, you can add it in the app after the release. You choose a voice for it, and then the chapters are created one after another; this can take some time. The voice cannot be changed afterwards.
11. Withdrawal and refunds
- (1)
Purchases in the app: the respective store is the seller. Whether and how you can withdraw from a purchase or get a refund is governed by its terms. With Apple, you request a refund at reportaproblem.apple.com, with Google Play through the order history of your Google account.
- (2)
Orders through our website: we are the seller (section 1(4)). You request a refund by email to sternenschmied96@gmail.com.
- (3)
We make the Meisterbuch specifically for you, according to your personal data. For such goods, the law provides no right of withdrawal (Section 312g(2) No. 1 of the German Civil Code, BGB). For the digital edition you agree at checkout that we start at once; your right of withdrawal ends once the book has been created (Section 356(5) BGB). Any further rights you have under the terms of the store remain unaffected, as does the cancellation until the release (section 10(4)).
- (4)
Your statutory rights in the event of defects, such as printing errors or damage in transit, remain in any case.
12. Referral programme
- (1)
With your personal referral code, you can invite others to UmbraLux. If someone redeems your code in the app, you both get 7 days of Premium. If you already have gifted Premium time running, we add the days at the end; a paid subscription is not extended by this.
- (2)
For several successful referrals, you get the following in addition to the 7 days per referral:
- with the 3rd referral, 30 days of Premium and a badge,
- with the 5th referral, the “Yearly Forecast” report,
- with the 10th referral, 90 days of Premium and a badge,
- with the 15th referral, the “Master Profile” report,
- with the 20th referral, 60 days of Premium and a badge,
- with the 25th referral, Lifetime Premium and a badge.
- (3)
Each account can redeem only one code, and you cannot redeem your own code.
- (4)
Rewards have no cash value and cannot be paid out or transferred. If you create fake or multiple accounts or misuse the programme in any other way, we may refuse rewards or take them back.
- (5)
We may change or end the referral programme for the future. Rewards you have received up to then remain yours.
13. Your content and our rights
- (1)
The app, its texts, graphics and audio, and the library are legally protected. You may use them for private purposes for the duration of the contract; this right is non-exclusive and not transferable.
- (2)
You may use your reports, your Meisterbuch and the associated files privately, print them and share them with people close to you. Commercial use or publication requires our consent.
- (3)
You keep all rights to your own content, that is, your messages, images and information. You allow us to use it as far as we need to for the app, for example to store it and send it to our AI service providers. Only upload content to which you hold the necessary rights; this also applies to the dedication in the Meisterbuch.
14. What is not allowed
- (1)
You use UmbraLux only for yourself. In particular, you may not
- use the app in an automated way or through scripts,
- get around limits or blocks,
- create several accounts in order to get free periods or rewards more than once,
- upload or spread unlawful content,
- decompile or replicate the app, unless the law expressly allows it.
- (2)
If you seriously breach these rules, we may block the feature concerned for you and, in serious cases, terminate the contract (section 16(5)).
15. Availability and changes
- (1)
We strive for high availability. However, we cannot promise uninterrupted access, for example during maintenance or disruptions at our service providers.
- (2)
We keep developing UmbraLux. Beyond what is necessary to keep the app in conformity with the contract, we only change it for a valid reason, for example because of new legal requirements, for security reasons, because of technical developments or because we realign our offer. This causes you no additional costs, and we inform you clearly and comprehensibly about the change.
- (3)
If a change impairs your access to the app or its usability more than only insignificantly, we inform you in good time beforehand on a durable medium, for example by email, about the nature and timing of the change and about your rights. You can then end the contract free of charge within 30 days, unless you keep the unchanged app at no additional cost. The period starts when the information reaches you or, if the change only comes afterwards, with the change.
- (4)
We do not keep chat histories indefinitely. We delete the messages of finished chats about three and a half months after the last message; pinned chats are exempt. The title, the summary and what Verus has remembered stay. Details are in our privacy policy.
- (5)
If we ever discontinue UmbraLux altogether, we will tell you with reasonable notice.
16. Term, termination and account deletion
- (1)
The contract for using the app runs for an indefinite period. You can end it at any time by deleting your account in the app (Settings › “Delete Account”) or by asking us to by email. You can find step-by-step instructions on our Delete account page.
- (2)
You cancel running subscriptions separately in your store’s subscription settings; deleting your account does not cancel them.
- (3)
With your account, all content and unlocks that belong to it are removed, including purchased reports, your Meisterbuch in the app with its PDF and audiobook, credits and Premium time. We can no longer print and ship a Meisterbuch that we have not yet sent to print.
- (4)
Beforehand, you can save a copy of your data under “Export Data” (complete from app version 2.1).
- (5)
We may terminate the contract without notice for good cause, in particular in the event of serious breaches of these terms.
17. Liability
- (1)
We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and to the extent of any guarantee we have given.
- (2)
If we slightly negligently breach an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose fulfilment you may regularly rely, we are only liable for the typical, foreseeable damage.
- (3)
Otherwise, we are not liable for slight negligence.
- (4)
Your statutory rights in the event of defects remain unaffected.
18. Data protection
Our privacy policy explains how we process your data.
19. Changes to these terms
- (1)
We will tell you about new versions of these terms in the app beforehand. They only apply to you once you agree to them.
- (2)
If you agreed to an earlier version, it continues to apply to you until you agree to the new one. You can find earlier versions at the end of this page.
20. Dispute resolution and final provisions
- (1)
We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.
- (2)
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you additionally keep the protection of the mandatory provisions of the country in which you have your habitual residence.
- (3)
If you are a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is our place of business.
- (4)
The contract languages are German and English; both versions of these terms are equally binding. You can view, save and print these terms at any time at umbralux.app/en/terms.
