A plain-language
agreement.

1Acceptance of these Terms

By downloading, installing, opening, or otherwise using Marrigo (the "App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the App and uninstall it. These Terms form a legal agreement between you ("you", "User") and Andrii Matiushev, an independent developer trading under the brand name "Zydeno" ("Zydeno", "we", "us"), the developer of Marrigo. "Zydeno" is a brand name and not a separate legal entity; the contracting party is Andrii Matiushev as an individual.

These Terms reference and incorporate our Privacy Policy, which explains how the App handles data. Together, they govern your use of Marrigo.

2Who we are

Zydeno is the studio brand of Andrii Matiushev, an independent developer who builds privacy-first iOS applications. There is no separate company behind it — no investors, no advertising department, no sales team, just one developer. Marrigo is distributed on the Apple App Store by Andrii Matiushev under the bundle identifier com.marrigo.wedding.planner.

Our only contact channel is [email protected]. Mail to that address reaches the developer directly. For postal correspondence, write to that email and we'll provide an address.

3License to use the App

Subject to your compliance with these Terms, Zydeno grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable, limited license to download, install, and use Marrigo on any Apple-branded device that you own or control, solely for your personal and non-commercial purposes (including planning your wedding, helping a family member or friend plan theirs, or experimenting with the app).

This license is granted under the Apple App Store's "Licensed Application End User License Agreement" (the "Apple EULA"), which is the baseline agreement between you and Apple, and these Terms, which supplement it for matters specific to Marrigo.

You may not:

• copy, modify, translate, adapt, or create derivative works of the App, except as expressly permitted by law (such as decompilation rights granted under EU Directive 2009/24/EC for the limited purpose of interoperability);
• reverse engineer, disassemble, or otherwise attempt to derive the source code of the App, except as permitted by mandatory law;
• rent, lease, lend, sell, redistribute, sublicense, or commercially exploit the App;
• remove or alter any proprietary notices on the App or its documentation;
• use the App for any unlawful purpose or in any way that infringes the rights of others.

We reserve all rights not expressly granted to you. Future versions of the App may be governed by updated terms; this license applies to the version you currently have installed unless and until you accept new terms.

4Apple's Standard End User License Agreement

Where applicable, Apple's Licensed Application End User License Agreement applies to your use of Marrigo as an App Store application. To the extent these Terms conflict with Apple's EULA in respect of Apple-imposed terms (for example, on Apple's role as a third-party beneficiary, on maintenance responsibility, on product claims, on intellectual property infringement claims), the Apple EULA controls. Otherwise, these Terms apply.

You acknowledge and agree that:

• These Terms are concluded between you and Zydeno only, and not with Apple. Apple is not responsible for the App or its content.
• The license granted in section 3 is limited to a non-transferable license to use the App on any Apple-branded products that you own or control and as permitted by the Apple Usage Rules in the Apple Media Services Terms and Conditions.
• Zydeno (not Apple) is solely responsible for providing any maintenance and support services for the App. You can reach us at [email protected].
• Zydeno is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) of the App; to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App.
• Zydeno, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your use of the App, including (i) product liability claims, (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement, and (iii) claims arising under consumer protection or similar legislation.
• In the event of any third-party claim that the App or your use of the App infringes that third party's intellectual property rights, Zydeno will be solely responsible for the investigation, defense, settlement, and discharge of any such claim.
• You will comply with all applicable third-party terms of agreement (e.g., your wireless data service agreement) when using the App.
• Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance, 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.

5No account, age, and eligibility

Marrigo does not have an account system. You sign in to your device with your Apple ID (managed by Apple); we do not see it. Therefore there is no Marrigo password to remember, lose, or be compromised.

To use Marrigo, you must be old enough to enter into a legally binding contract in your jurisdiction (generally 18, sometimes 13–16 with parental consent in some jurisdictions). The App is rated 4+ on the App Store because it contains no objectionable content, but it is functionally designed for adults planning a wedding.

You are responsible for ensuring that your use of the App is permitted in your country and that any personal data of third parties (e.g., guests) you enter is handled in accordance with applicable law — see section 7.

6Acceptable use

You agree not to use Marrigo to:

• violate any law or regulation, including data protection, anti-spam, anti-fraud, or export control laws;
• send unsolicited messages, including RSVP invitations, to people who have not agreed to receive communications from you;
• upload, store, or share content that is unlawful, defamatory, obscene, infringing, harassing, threatening, hateful, sexually explicit, or otherwise objectionable;
• impersonate any person or misrepresent your affiliation with any person or organization;
• upload viruses, worms, trojan horses, time bombs, or any other malicious code;
• interfere with, disrupt, or attempt to gain unauthorized access to Apple's CloudKit infrastructure, the App, or other users' data;
• use the App in a way that could harm Apple, Zydeno, or any third party, or that interferes with the normal operation of the App;
• use AI features (Vow Coach, thank-you generator, AI moodboard) to produce content that is hateful, defamatory, sexually explicit, or otherwise prohibited by Apple's guidelines or applicable law;
• use Marrigo's RSVP, email-template, or vendor inquiry features to send spam, phishing, or commercial solicitation to third parties.

Because we do not run servers, we cannot moderate or remove content from inside Marrigo. You are wholly responsible for what you put into the app.

7Your content

"Your Content" means everything you create, upload, import, or generate inside Marrigo — guest names, contact details, vendor records, photos, journal entries, voice memos, AI-generated drafts you keep, custom playlists, and so on.

7.1 You own your content

You retain full ownership of Your Content. Zydeno claims no license, no ownership, and no usage right over Your Content. We never touch it.

7.2 Your responsibility for guest data

If you import contacts or otherwise add a third party's personal data (name, email, phone, dietary requirements, address) to Marrigo, you must have a lawful basis to do so under applicable data protection law (GDPR, UK GDPR, LGPD, PIPL, CCPA, etc.). Typically, this means consent or a legitimate interest. You are the data controller in respect of the personal data of your guests, and Zydeno is not a processor of that data because we never receive it.

7.3 Backups and exports

Marrigo lets you export CSV, PDF, JSON, and (optionally) encrypted backups. Once exported, those files are outside the app's protection and your responsibility to handle.

8AI-generated content

Marrigo includes AI features (Vow Coach, thank-you drafts, AI Moodboard, photo tagging) built on Apple Intelligence. These run on-device or, where Apple chooses, through Apple's Private Cloud Compute. Zydeno does not operate AI models; we orchestrate calls to Apple's frameworks.

Regarding any AI output you obtain through the App:

• It is a draft, not advice. AI output may be inaccurate, awkward, or culturally inappropriate. You are responsible for reviewing and editing any output before using it.
• You assume the consequences of using it. Reading a generated vow aloud at your ceremony, sending an AI-drafted thank-you note, or printing an AI-generated moodboard is your decision.
• Ownership of AI output varies by jurisdiction. To the extent ownership is possible, Zydeno claims no rights over output you generate. You may use AI output for personal, non-commercial wedding-related purposes consistent with these Terms.
• Originality is not guaranteed. AI output may incidentally resemble existing works. We make no representation that AI output is original or non-infringing.
• Apple's terms also apply. Your use of Apple Intelligence is subject to Apple's terms governing Apple Intelligence features.

9Third-party services

Marrigo may help you launch or hand off to third-party services at your request:

• Apple system apps — Apple Music, Maps, Mail, Phone, Find My, Photos, Contacts, and Apple Wallet (for optional guest passes, only when the feature is enabled) — are Apple-provided integrations, governed by Apple's terms. Marrigo opens or hands off to them only when you tap something.
• Spotify and Apple Music links — if you paste a Spotify or Apple Music URL into a playlist slot or the first-dance field, Marrigo can open it in that app or web player. Marrigo does not search, stream, or play music itself. Spotify use is subject to Spotify's Terms; Apple Music to Apple's Media Services Terms.

Marrigo does not process, hold, or transfer money for anything other than your optional Premium purchase (which Apple handles — see section 14). Zydeno does not endorse, control, or assume responsibility for any third-party service. Their terms, fees, and privacy policies apply when you use them.

10iCloud sync and partner sharing

Marrigo uses Apple's CloudKit to sync your data across your Apple devices via your private iCloud database, and (optionally) to share a wedding with one partner via CloudKit Share. The data resides in your Apple iCloud account, not on Zydeno servers. Your use of iCloud is governed by Apple's iCloud Terms.

If you invite a partner to share a wedding (a Marrigo Premium feature), you authorize Apple's CloudKit Share infrastructure to deliver the invite and maintain shared access. Partner sharing is a read-only overview — your partner sees a published snapshot of high-level details (couple names, date, venue, headline counts, a few timeline items), not a live, co-editable copy of your full data. Marrigo does not represent partner sharing as real-time collaboration. You can revoke the share at any time from inside the app or from Settings → Apple ID → iCloud.

Zydeno is not responsible for the availability, reliability, or content of Apple's CloudKit service, for partner access to shared records, or for synchronization issues caused by Apple's infrastructure. We disclaim liability for any loss, corruption, or unavailability of data stored in iCloud.

11Public RSVP & guest-facing data

If you enable the public RSVP snapshot or the public guest photo album, Marrigo publishes content to Apple's CloudKit public database tied to your iCloud container. For RSVP, this is a minimal, read-only snapshot (such as event name and date); the app does not receive guest responses through any Zydeno server, because there is no Zydeno server. For the guest album, people with the link can upload photos to, and view, that album. Anyone with a link can view what you publish, so you are responsible for whom you share the link with.

You agree that you have the right to publish any wedding information (event name, date, venue, dress code) you include, and that you will not include any sensitive personal data of third parties without their consent.

You may unpublish a public RSVP snapshot, or delete a shared album, at any time. After unpublishing, copies that guests have already downloaded are not under our control.

12Marrigo is a planning tool, not a wedding service

Marrigo helps you organize information about your wedding. It is not:

• a wedding-planning agency,
• a vendor marketplace or directory,
• a payment platform,
• a booking engine for venues, photographers, florists, caterers, DJs, officiants, or any other vendor,
• a contract execution platform,
• an insurance provider,
• a legal or financial advisor,
• a religious or civil officiant or marriage registrar.

All vendor relationships, contracts, bookings, deposits, refunds, no-shows, disputes, claims, and the actual occurrence of your wedding are between you and the relevant third parties. Zydeno is not a party to any such relationship and has no liability for it.

Suggested budget allocations, day-of timelines, golden-hour times, checklist templates, vendor category suggestions, sustainability scores, astrology overlays, and any other algorithmic outputs are guidance only. They are based on general assumptions and may not be appropriate for your specific wedding.

13Availability, updates, and support

We try to keep Marrigo working, but we make no commitment that the App will be available without interruption, error-free, or compatible with every device or iOS version. From time to time we may release updates that change, add, or remove features. We may also decide to discontinue features that have low usage or that no longer fit the product direction. Apple may, at its discretion, withdraw, restrict, or modify the App's availability on the App Store.

Because Marrigo has no servers, the App will continue to work locally on your device even if Zydeno stops releasing updates. Apple's iCloud service is needed for sync; we cannot guarantee iCloud's continued availability.

Support is provided on a best-effort basis via [email protected]. There is no paid support tier or guaranteed response time.

14Fees, subscriptions, in-app purchases, and refunds

14.1 Free core, optional Premium

Marrigo's core functionality is free. An optional upgrade, Marrigo Premium, unlocks additional tools (such as branded PDF exports, the seating planner, the venue 3D scanner, AI Vow Coach, the AI moodboard, premium themes, guest analytics, bulk import, partner sharing, and an unlimited guest list). Free generous limits apply before an upgrade is suggested (for example, a number of guests, expenses, and timeline items); editing or deleting what you already created is never blocked.

Marrigo Premium is offered through Apple's In-App Purchase as the following products:

* Prices are shown in US dollars. Apple presents the actual price in your local currency, and the exact, current price is always displayed on the in-app purchase screen before you confirm. The monthly and yearly subscriptions belong to one subscription group ("Marrigo Premium"); buying one replaces the other on its next renewal.

14.2 Free trial

The monthly subscription may include a 7-day free trial for eligible new subscribers. Unless you cancel at least 24 hours before the trial ends, the subscription automatically converts to a paid monthly subscription and your Apple ID is charged. Any unused portion of a free trial is forfeited if you purchase a subscription before the trial ends. Free-trial eligibility is determined by Apple.

14.3 Auto-renewal terms (subscriptions)

For the auto-renewable subscriptions above, the following standard terms apply:

• Payment is charged to your Apple ID account at confirmation of purchase.
• The subscription automatically renews at the same price for the same period unless auto-renewal is turned off at least 24 hours before the end of the current period.
• Your account is charged for renewal within 24 hours prior to the end of the current period, at the price of the selected plan.
• You can manage your subscription and turn off auto-renewal after purchase in your device's Settings → [your name] → Subscriptions (App Store account settings).
• Deleting the app does not cancel a subscription. You must cancel through Apple.

14.4 Lifetime (one-time purchase)

The Lifetime product is a non-consumable, one-time purchase — there is no recurring charge and nothing to cancel. It unlocks Premium features for the Apple ID that bought it, including via Family Sharing where Apple makes that available, and can be restored with "Restore Purchases" on the paywall.

14.5 Restoring purchases

The paywall includes a Restore Purchases button. Restoring asks Apple to re-confirm an active subscription or a previous Lifetime purchase tied to your Apple ID and re-enables Premium on the device. It involves Apple only — no Zydeno account, login, or server.

14.6 Refunds

Purchases are made from, and refunds are handled by, Apple, not Zydeno. To request a refund, use reportaproblem.apple.com or Settings → [your name] → Media & Purchases → Purchase History. Statutory rights to cancel or to a refund for digital content (see section 21) are not affected.

14.7 Price changes

We may change Premium pricing or the plans we offer. Any change applies on a going-forward basis. For auto-renewable subscriptions, Apple notifies you of a price increase and, where required, asks for your consent before the increase takes effect; if you do not agree, the subscription will not renew at the new price. Changes never affect a Lifetime purchase you have already made.

14.8 Other costs

You are responsible for any other costs of using the App on your device, including mobile data, electricity, hardware, and iCloud storage above Apple's free tier.

15Intellectual property

Marrigo, including its name, logo, code, design, screen layouts, copy, sounds, animations, icon variants, brand palette, and documentation, is the intellectual property of Andrii Matiushev (trading as Zydeno), protected by copyright, trademark, design, and other laws. "Marrigo" and "Zydeno", and the Marrigo wordmark, are trademarks of Andrii Matiushev.

"Apple", "iPhone", "iPad", "Mac", "Apple Watch", "iCloud", "CloudKit", "Apple Intelligence", "Apple Music", "App Store", "AirTag", "Live Activity", "Dynamic Island", "TestFlight", "Image Playground", "Vision", "Speech", "SwiftData", and related marks are trademarks of Apple Inc., used here for descriptive purposes only. Other product and company names mentioned in the App or this document are trademarks or registered trademarks of their respective owners and are used for identification only.

Nothing in these Terms grants you any right, license, or interest in or to any Zydeno or third-party intellectual property except the limited license described in section 3.

16Feedback

If you send us suggestions, ideas, feature requests, bug reports, screenshots, or any other feedback ("Feedback"), you grant Zydeno a perpetual, irrevocable, royalty-free, worldwide, sublicensable license to use, reproduce, modify, publish, distribute, and exploit that Feedback in any manner, without compensation or attribution. You confirm that the Feedback is yours to give and does not contain confidential information of a third party.

17Disclaimers

Some jurisdictions do not allow the exclusion of certain warranties, so portions of the above disclaimer may not apply to you. Nothing in these Terms excludes or limits Zydeno's liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot be excluded under applicable law.

18Limitation of liability

This section does not limit liability that cannot be excluded under applicable law (for example, liability for gross negligence or willful misconduct in some jurisdictions). Where mandatory consumer law applies (see section 21), our liability for non-conforming digital content is governed by that law and not by this cap.

19Indemnification

You agree to indemnify, defend, and hold harmless Zydeno, its affiliates, officers, employees, agents, and licensors from and against any and all claims, liabilities, damages, losses, costs, expenses, and fees (including reasonable legal fees) arising out of or relating to: (a) your breach of these Terms; (b) your violation of any law or the rights of any third party (including guests, vendors, and partners); (c) Your Content and your handling of personal data of third parties through the App; (d) your use of AI-generated content beyond the App.

This indemnification obligation is reduced to the extent that the underlying claim arises from Zydeno's gross negligence or willful misconduct, and it does not apply where mandatory consumer protection law prevents it.

20Termination

You can terminate this agreement at any time by deleting the App and (optionally) erasing the Marrigo iCloud container. No notice required.

Zydeno may terminate or suspend your license under these Terms with or without notice if you materially breach these Terms or if continued provision of the App becomes commercially or technically impracticable. Because there is no account, "termination" by us is functionally equivalent to ceasing to release updates to your version of the App; you may continue to use the version installed on your device subject to these Terms.

Sections that by their nature should survive termination (intellectual property, disclaimers, limitation of liability, indemnification, governing law, miscellaneous) shall survive.

21Consumer rights (EU, UK, and other jurisdictions)

If you are a consumer resident in the European Economic Area, the United Kingdom, Switzerland, or another jurisdiction that grants statutory consumer protections, those protections apply to your use of Marrigo and override any conflicting provision of these Terms.

In particular, nothing in these Terms is intended to limit or exclude:

• statutory rights under the EU Digital Content Directive (2019/770) and the EU Sale of Goods Directive (2019/771) — for example, the right to a conformity remedy if the App does not work as described;
• statutory rights under the UK Consumer Rights Act 2015;
• your statutory right of withdrawal for paid digital content and services (for example, the 14-day withdrawal right in the EU and UK), subject to the rules that apply when digital content is supplied immediately with your prior consent. For purchases made through the App Store, Apple is the merchant of record and handles withdrawal, cancellation, and refund requests; and
• any other mandatory consumer protection rules of the country where you habitually reside.

If you would like to lodge a complaint, please contact [email protected] first. EU consumers can also use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr, although we are not obliged to engage in ODR proceedings.

22Governing law and disputes

These Terms are governed by the laws of the country in which the developer (Andrii Matiushev, trading as Zydeno) is resident (the "Governing Jurisdiction"). The specific governing-law jurisdiction is identified upon written request to [email protected].

Any dispute, controversy, or claim arising out of or in connection with these Terms or the App that cannot be resolved amicably shall be submitted to the exclusive jurisdiction of the courts of the Governing Jurisdiction, except that:

• if you are a consumer, you may also bring proceedings in the courts of the country where you reside, and those courts may apply mandatory consumer protection rules of your country of residence;
• nothing in this section prevents Zydeno from seeking injunctive or equitable relief in any court of competent jurisdiction;
• section 4 (Apple's Standard EULA) controls in matters between you and Apple as a third-party beneficiary.

This section does not deprive you of the protection of any mandatory consumer law of your country of habitual residence.

23Export, sanctions, and prohibited use

You represent and warrant that (a) you are not located in a country that is subject to a comprehensive U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (b) you are not listed on any U.S. Government list of prohibited or restricted parties. You agree to comply with all applicable export, re-export, and sanctions laws and regulations.

24Changes to these Terms

We may update these Terms from time to time. The "Last updated" date at the top of this page reflects the most recent version. Material changes will be highlighted in the in-app release notes for the affected version. If you continue to use Marrigo after the updated Terms are effective, you accept the changes. If you do not accept them, your remedy is to stop using the App (see section 20).

25Miscellaneous

• Entire agreement. These Terms, together with the Privacy Policy and the Apple EULA, constitute the entire agreement between you and Zydeno regarding Marrigo.
• Severability. If any provision of these Terms is found to be unenforceable, the remaining provisions remain in full effect, and the unenforceable provision is replaced by an enforceable provision that most closely reflects the original intent.
• Waiver. No failure or delay by Zydeno in exercising any right under these Terms shall operate as a waiver of that right.
• Assignment. You may not assign or transfer these Terms, in whole or in part. Zydeno may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of its assets.
• Force majeure. Neither party will be liable for any failure or delay in performance caused by circumstances beyond its reasonable control (acts of God, war, pandemic, embargo, internet outage, Apple service outage, etc.).
• No agency. Nothing in these Terms creates any agency, partnership, joint venture, or employment relationship between you and Zydeno.
• Language. The English version of these Terms is the controlling version. Translations into other languages are provided for convenience only.
• Notices. All notices to Zydeno must be sent to [email protected]. Notices to you may be delivered via in-app messages, App Store release notes, or by email if you have provided one.
