These Terms of Service ("Terms") form a legally binding agreement between you and MAVK ANALYTICS LTD ("we", "us", "Duetto") governing your use of the Duetto Telegram bot and Mini App, the Duetto iOS application, the website at theduetto.com, and related services (together, the "Service").
For the iOS application, these Terms are the end-user licence agreement (EULA). By downloading, installing, or using the Duetto app, or by otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.
1. About us
The Service is operated by MAVK ANALYTICS LTD, a private limited company registered in England and Wales (company number 17024096), with registered office at 20 Wenlock Road, London, England, N1 7GU.
Contact: legal@theduetto.com · support@theduetto.com
2. What the Service does
Duetto provides personalised astrological and tarot content, including natal chart readings, daily transits, synastry (compatibility) readings, composite charts, and AI-generated narrative interpretations. Astronomical positions are computed with the Swiss Ephemeris from the birth data you provide; the narrative text is generated by an AI language model.
The Service is provided for entertainment and informational purposes only. It is not professional advice of any kind, including but not limited to medical, mental health, psychological, financial, legal, relationship, or career advice. Do not rely on the Service to make important life decisions. If you are in distress or considering decisions about your health, safety, finances, or relationships, consult a qualified professional.
3. Eligibility
You must be at least 18 years old to use the Service. By using it, you represent that you are 18 or older. We reserve the right to terminate the account of any user we reasonably believe to be under 18 and delete their data.
4. Your account
How you are identified depends on the platform you use:
- Telegram — authentication is performed through Telegram. You do not create a Duetto password; your account is linked to your Telegram user ID.
- iOS app — you can start using the app as a guest. In that case the app generates a random device identifier, stores it in the device keychain, and uses it to recognise your account. Where the app offers Sign in with Apple, using it links your account to the Apple-issued identifier so you can restore it on another device.
You are responsible for the security of the account you authenticate with (Telegram or Apple); we are not responsible for losses arising from a compromise of those credentials.
Guest accounts are tied to the device. If you use the iOS app as a guest and delete the app, reset the device, or move to a new device without linking a durable sign-in method, we may be unable to restore your readings or purchases.
You agree to provide accurate birth data. The accuracy of readings depends on accurate input.
You may delete your account at any time from within the app. Some data is retained as described in our Privacy Policy.
5. Acceptable use
You agree not to:
- Use the Service for any unlawful purpose or in violation of any applicable laws
- Use the Service if you are under 18
- Scrape, crawl, or use automated means to access the Service beyond the rate limits we set
- Reverse engineer, decompile, or attempt to extract the source code of the Service, except to the extent expressly permitted by mandatory law
- Resell, redistribute, or commercially exploit readings or other Service content
- Interfere with, disrupt, or place an undue load on the Service or its infrastructure
- Use the Service to harass, threaten, defame, or harm any other person
- Impersonate another person or provide false identity information
- Probe, scan, or test the vulnerability of the Service without our prior written consent
- Use the Service to develop a competing product or to train an AI/ML model
- Submit content that is unlawful, infringing, harmful, or that you do not have the right to submit
We may suspend or terminate your access for any breach of these Terms.
6. Payments, purchases, and subscriptions
6.1 General
Part of the Service is free. Paid features are sold only through the platform store you are using — we never take card details directly. Prices, the applicable currency, and any taxes are shown to you inside the app before you confirm a purchase, and you authorise the charge by completing the purchase.
6.2 Telegram Stars (Telegram Mini App)
Purchases inside the Telegram Mini App are made with Telegram Stars and processed by Telegram FZ-LLC under Telegram's own terms and rates. Telegram Stars purchases are one-off: they unlock a specific reading or a defined period of access (for example, 30 days of transit access). They do not auto-renew, and no further charge is made when the access period ends.
6.3 Apple App Store (iOS app)
Purchases in the iOS app are made through Apple in-app purchase. Apple is the merchant of record for these transactions, acting as our agent or commissionaire; payment is charged to your Apple Account. Two kinds of products are offered:
- Consumable purchases — a one-off unlock of a specific reading. They do not renew.
- Auto-renewable subscriptions — recurring access to a set of features for a fixed period. See § 6.4.
6.4 Auto-renewable subscriptions (iOS)
Where the iOS app offers an auto-renewable subscription, the following applies:
- The title of the subscription, the length of each subscription period, the features it unlocks, and the price are shown on the purchase screen in the app and on the App Store product page before you buy.
- Payment is charged to your Apple Account at confirmation of purchase.
- The subscription renews automatically unless auto-renewal is turned off at least 24 hours before the end of the current period.
- Your Apple Account is charged for renewal within 24 hours prior to the end of the current period, at the price then in effect for your subscription.
- You can manage your subscription and turn off auto-renewal at any time after purchase in Settings → your name → Subscriptions on your device, or in your Apple Account settings. We cannot cancel an Apple subscription for you.
- Cancelling stops future renewals only. The current paid period is not cancelled or refunded, and you keep access until it ends.
- Where a free trial is offered, any unused portion of a free trial period is forfeited when you purchase a subscription covering the same content.
- Deleting the app does not cancel a subscription. You must turn off auto-renewal as described above.
6.5 Price changes
We may change prices and the products we offer at any time. A price change does not affect a subscription period you have already paid for. For auto-renewable subscriptions, Apple will notify you of a price increase and, where required by Apple's rules or applicable law, will ask for your consent before the increase takes effect; if you do not consent, the subscription will not renew.
6.6 Refunds
Refunds are governed by our Refund Policy. In short: Telegram Stars purchases are refunded through Telegram, and App Store purchases are refunded by Apple, at Apple's discretion, via reportaproblem.apple.com. Your statutory rights as a consumer are not affected.
7. Additional terms for the iOS application (Apple)
These terms apply to your use of the Duetto iOS app and are required by Apple. In them, "Application" means the Duetto iOS app.

- Product claims.

- Intellectual property claims. In the event of any third-party claim that the Application or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement, and discharge of that claim.
- Legal compliance. You represent and warrant that (i) you are not located in a country subject to a US Government embargo or designated by the US Government as a "terrorist supporting" country, and (ii) you are not listed on any US Government list of prohibited or restricted parties.
- Third-party terms. You must comply with any applicable third-party terms of agreement when using the Application.

8. Intellectual property
All content generated by the Service — including the structure, design, code, astrological models, narrative templates, and brand elements — is owned by or licensed to MAVK ANALYTICS LTD and protected by copyright and other intellectual property laws.
We grant you a personal, non-exclusive, non-transferable, revocable licence to access and use your readings for your own personal, non-commercial use. You may share individual readings with friends in private contexts and on social media for personal purposes. You may not resell readings or include them in any commercial product.
The data you provide (your name, birth data, partner data) remains yours. By submitting data, you grant us a licence to use it to deliver the Service to you as described in our Privacy Policy.
9. Third-party services
The Service relies on Telegram and Apple for distribution, authentication, and payments, on an AI provider for narrative generation, and on infrastructure providers for hosting. Your use of those third-party services is subject to their respective terms. We are not responsible for the acts or omissions of third parties. The subprocessors we use are listed in our Privacy Policy.
10. AI-generated content
Narrative interpretations are generated by an AI language model. AI output can be inaccurate, inconsistent, or surprising. We do not warrant that any specific reading is accurate, complete, or fit for any particular purpose. AI content is for entertainment.
11. Service availability
We aim to make the Service available continuously, but we do not guarantee uninterrupted access. We may suspend or modify any part of the Service at any time, with or without notice, for maintenance, upgrades, security, or any other reason. If we permanently discontinue a paid feature you are subscribed to, we will stop future renewals and, where required by law, refund the unused portion of a period you have paid for.
12. Disclaimer of warranties
To the maximum extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, or uninterrupted operation. We do not warrant that the Service will meet your expectations or that any reading will be accurate.
Nothing in these Terms excludes or limits liability where it would be unlawful to do so under English law, including liability for death or personal injury caused by negligence or for fraud.
13. Limitation of liability
To the maximum extent permitted by law:
- Our total aggregate liability to you in connection with the Service is limited to the greater of (a) the amount you paid us in the 12 months preceding the event giving rise to the claim, or (b) £50.
- We are not liable for any indirect, incidental, consequential, special, exemplary, or punitive damages, including lost profits, lost revenue, lost data, loss of goodwill, or business interruption.
- We are not liable for any decision you make based on a reading.
If you are a consumer in the UK or EU, these limitations do not affect your statutory rights.
14. Indemnity
You agree to indemnify and hold us harmless against any claim, loss, or expense (including reasonable legal fees) arising from your breach of these Terms, your misuse of the Service, or your violation of any law or third-party right.
15. Termination
You may stop using the Service and delete your account at any time. Deleting your account does not cancel an auto-renewable subscription — turn off auto-renewal in your Apple Account settings as described in § 6.4. We may suspend or terminate your access at any time for breach of these Terms or if required by law. On termination, the provisions that by their nature should survive (intellectual property, disclaimers, limitations, indemnity, governing law, dispute resolution) will survive.
16. Changes to these Terms
We may update these Terms from time to time. We will update the "Last updated" date at the top. For material changes, we will notify you in-app at least 14 days before the change takes effect. Continued use of the Service after a change constitutes acceptance.
17. Governing law
These Terms and any non-contractual obligations arising out of or in connection with them are governed by the laws of England and Wales.
18. Dispute resolution and jurisdiction
The courts of England and Wales have exclusive jurisdiction to resolve any dispute arising out of or in connection with these Terms.
If you are a consumer resident in the UK or the EEA, you also have the right to bring proceedings in the courts of your country of residence, and you have the protection of mandatory consumer-protection laws of your country of residence.
The European Commission's Online Dispute Resolution platform ceased operations on 20 July 2025. EU consumers can contact their national consumer authority or the European Consumer Centre in their country of residence; UK consumers can contact Citizens Advice.
19. Severability
If any provision of these Terms is held to be unenforceable, the remaining provisions will continue in full force, and the unenforceable provision will be interpreted as closely as possible to its original intent.
20. Entire agreement
These Terms, together with our Privacy Policy, Refund Policy, and Cookie Policy, constitute the entire agreement between you and us regarding the Service.
