1. Provider and scope
The SeatHarmony digital service is provided by Christopher Gobien, acting in his own name as a natural person, Ofterdingenstr. 42, 45279 Essen, Germany. Email: admin@seatharmony.net. Telephone: +49 179 6724793. Wirtschafts-Identifikationsnummer under section 139c AO: DE464562297-00001.
These Terms apply to private users and professional customers, including event planners and businesses. A consumer acts mainly outside a trade, business or profession; mandatory consumer protections at that person's habitual residence remain unaffected. A person accepting for an organisation confirms authority to bind it. The professional processing terms below form part of this agreement where SeatHarmony processes personal data on the customer's instructions.
SeatHarmony is intended only for people aged 18 or older. By accepting these Terms, the user confirms that they are at least 18 and permitted to enter into this agreement.
2. SeatHarmony service and accounts
SeatHarmony supports guest lists, tables, room layouts, seating preferences, checks, exports and reviewable AI suggestions. Supported native apps and the web app can be used without a registered account for limited local planning. This mode permits one local plan in total (active or archived) with up to six tables, 40 guests and five room elements; the features and limits shown in the app determine what else is available.
A browser-local plan is stored only in that browser profile where local storage is supported. It is not a cloud backup and can be lost if the user clears site data, the browser evicts local data, the profile is removed, or the private browsing session in which it was created ends.
You can create a SeatHarmony account for free in the web, Android or iPhone app. Creating an account preserves your existing local plans. With a verified email address, plans and their saved images synchronize across devices without Planner Plus. Purchases and purchase restoration take place in the mobile app; account creation does not activate paid features.
The same account can be used on another device. Distinct local and account plans are preserved when connecting an account; competing changes to the same plan require review. A local plan is cloud-backed only after synchronization succeeds. Offline changes synchronize when connectivity returns. Deleting an account plan also removes it from other synced devices. Free planning limits apply to new work; existing plans remain accessible. In-app exports, printing and other marked premium tools require active, server-verified Planner Plus access. AI requests use account credits independently of Plus; your current plan limits and other premium restrictions still apply to accepted changes. Account management, synchronization, sign-out and deletion remain available after paid access ends; a payment or entitlement error does not itself remove the customer's work. Cloud plans and invitation content are subject to the 180-day inactivity policy described in the privacy notice; local plans are not automatically deleted by that policy.
Planner Plus includes household creation and editing, food and drink preferences, event service providers and guest invitations where offered. One stable QR belongs to each retained plan; public guest access requires active paid access and can be paused. Guests see names and completion progress, while previous answers remain private to the host. Guest submissions do not verify identity and require host review before changes are applied.
Customers must keep sign-in details secure and must be entitled to use any event and guest information they enter. SeatHarmony is not intended for health data, religious or political beliefs, biometric identifiers or other specially protected or highly sensitive guest data; such information must not be placed in names, tags, notes, prompts, images or recordings.
Each event allows up to three budget entries and five checklist tasks on Free, with unlimited entries and tasks on Planner Plus. Uploading budget attachments requires Planner Plus; supported files are PDF, JPEG, PNG and WebP up to 10 MiB each. Existing work remains accessible when paid access ends.
Address fields offer Google suggestions as you type. You can turn suggestions off in the field for manual-only entry. Opening or focusing a saved address does not start a search. The typed search text, selected language and a search-session token pass through the SeatHarmony server to Google Places. SeatHarmony does not log search text and saves only the street address you select in the event or service-provider address field. Suggested-address lists are not saved. You can always enter an address manually, including if search is unavailable.
This optional search uses Google Maps content. Use of this function is subject to the current Google Maps/Google Earth Additional Terms of Service at https://maps.google.com/help/terms_maps.html and Google Privacy Policy at https://policies.google.com/privacy. Google processes search requests under its applicable privacy information; no special Google retention or regional restriction is promised here.
3. Purchases through Apple App Store or Google Play
You cannot buy SeatHarmony subscriptions or AI-credit packs on this website. Purchases are processed through Apple App Store or Google Play in the Android or iPhone app. Planner Plus is activated after the store purchase is confirmed. Sign in or create a free account before buying or restoring a purchase. Creating an account does not require payment. The store checkout identifies the seller or contracting party, final price, currency, taxes, billing period, payment method and applicable store terms. That checkout and the store receipt are authoritative for the transaction.
Planner Plus is offered as a monthly subscription. There is no annual or one-year-then-monthly SeatHarmony subscription. The monthly subscription renews monthly until it is cancelled in the store where it was purchased.
RevenueCat receives store transaction and subscription information to reconcile SeatHarmony entitlements and AI credits. RevenueCat is not a separate SeatHarmony website checkout. SeatHarmony does not receive complete payment-card details.
4. Digital delivery, Planner Plus and AI credits
Digital access and AI credits belong to the account used for the verified purchase. Signing out does not transfer those benefits to a guest or another account. Planner Plus remains available while the subscription is active. Cancellation normally leaves access through the already paid period; refunds, revocations, chargebacks or failed payment can correct or end access where permitted.
Each verified monthly Planner Plus billing period adds the number of AI credits shown in the app and store offer. Optional AI-credit refills, where offered, are one-time in-app store purchases. Purchased and included monthly AI credits do not expire and can be used without Planner Plus within Free planning limits. Credits cannot be gifted, resold or redeemed for cash. Restore recovers verified benefits; it does not issue the same purchase or billing-period credits again.
Before sending an AI operation, SeatHarmony shows the maximum credit charge for authorization. Final settlement follows validated usage and cannot exceed that authorized maximum; unused reserved credits are released. Audio is recorded locally. Stop sends the completed recording in one request through the SeatHarmony backend to the paid OpenAI or Google Gemini API selected for transcription. Cancel before Stop discards the local recording without using AI credits. Successful transcription costs one AI credit per started minute, with a minimum of one credit, including when no speech is recognized and the result is empty. Provider or server failure is refunded. A completed analysis can incur a charge even if the user does not apply its suggestion or it finds no usable change. An interrupted response is recovered using the same operation identifier to avoid duplicate billing. Store refunds and revocations remove only the affected purchase benefits, including attributable unused credits. Unrelated purchases remain intact. Duplicate events and refund reversals cannot issue benefits twice. Mandatory refund and defect rights remain unaffected.
5. Subscription term and cancellation
Planner Plus is billed monthly by the originating app store and renews for another month unless cancelled under that store's rules. Customers can manage or cancel an Apple subscription in Apple App Store subscription settings and a Google Play subscription in Google Play subscription settings. The in-app Account area links to the applicable store when the origin is known.
SeatHarmony cannot cancel an Apple or Google subscription on the customer's behalf. Deleting a SeatHarmony account or deleting the app does not cancel the store subscription. Cancel the subscription with the originating store before deleting the account if renewal is not wanted.
The right to terminate for an important reason and other mandatory statutory termination rights remain unaffected.
6. Withdrawal and refunds
Purchase, withdrawal and refund requests must be made through the store that processed the transaction: Apple provides transaction support at https://reportaproblem.apple.com and Google provides order and refund support through Google Play Help. The informational withdrawal page links to those channels.
Whether a statutory withdrawal right exists, when it starts or expires, and who must process it depends on the store transaction, the contracting party identified there and mandatory law. Nothing in these Terms limits a mandatory withdrawal, refund, conformity or other consumer right.
Product or account-support questions may also be sent to admin@seatharmony.net, but contacting SeatHarmony does not replace a required store cancellation or store refund request.
7. Acceptable use and AI suggestions
SeatHarmony may not be used unlawfully, to infringe another person's rights, to attack or bypass the service, or to upload content the customer is not entitled to process.
Before the first AI operation, the app separately explains that selected planning context is sent through the SeatHarmony backend to the paid OpenAI or Google Gemini API selected for analysis and that selected audio is sent to the OpenAI or Google Gemini API selected for transcription. Floor-plan import uses the paid Google Gemini API. Acknowledging this notice does not replace the customer's responsibility to have a lawful basis and any required permission for guest data, images or recordings.
AI output is presented as a suggestion for human review and can be incomplete or wrong. The customer decides whether to apply it and must check placements, capacities, accessibility, safety and venue requirements. AI features must not be used for unlawful, harmful, medical or otherwise prohibited purposes.
8. Conformity and updates
Statutory rights for digital products apply, including the right to a conforming product and necessary updates for the legally required period. Where the legal conditions are met, customers may request a remedy, reduce the price or end the contract.
SeatHarmony may require reasonable maintenance and security updates. Planned maintenance and material changes will be communicated where required. A voluntary guarantee exists only if expressly stated separately.
9. End of access, account and data
When Planner Plus ends, in-app exports, printing and other premium tools stop after the verified access period. Remaining AI credits stay usable within Free planning limits. Account synchronization and free planning continue within their limits. Existing plans remain accessible, subject to identity verification and the retention rules in the privacy notice. Ending a subscription does not delete the account or its plans; account deletion and clearing local device or browser data are separate actions.
Customers should export information they need before deleting an account or losing access. SeatHarmony provides access, export or retrieval required by mandatory digital-product or data-protection law. Store, transaction and legal records may be retained where law requires or permits it.
10. Liability, applicable law and disputes
SeatHarmony is liable under applicable statutory rules. Nothing excludes liability for intent, gross negligence, injury to life, body or health, a statutory guarantee, product liability or another liability that cannot lawfully be limited.
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. This choice does not remove mandatory protections at the consumer's habitual residence. No exclusive court is agreed against a consumer.
The service provider is neither willing nor obliged to participate in dispute-resolution proceedings before a consumer arbitration board. Questions or complaints can be sent to admin@seatharmony.net.
11. Professional customer data processing
These processing terms form part of the agreement when SeatHarmony handles personal data on a professional customer's instructions. The customer is the registered account holder or the organisation represented by its authorised account holder. The customer must keep its identity and responsible contact details accurate and provide the organisation's legal name and contact details to SeatHarmony where it acts for one. SeatHarmony's provider identity and privacy contact are given in section 1.
The subject is the provision of cloud planning and optional AI for the service term, followed by return or deletion. Processing includes receiving, validating, storing, retrieving, synchronising, organising, exporting, generating proposals, transcribing selected audio and erasing. Data concerns the customer's users, event guests, organisers and venue contacts: names, attendance, guest tags, seating preferences and relationships, assignments, event/table/room labels and dimensions, and selected text, images or audio. Special-category and criminal-record data are outside the intended scope. Event data can also include budget amounts, checklist task details and selected budget files.
The customer determines the purpose and lawful basis, supplies required information to guests, minimises data and gives instructions through the functions it chooses or through documented support requests. A planner acting as a processor for an organiser must have authority to appoint SeatHarmony as a subprocessor. These terms do not make an otherwise unlawful upload lawful.
SeatHarmony processes this content only on documented instructions, including instructions about transfers outside the EEA. It does not use customer guest content to train a SeatHarmony model, build advertising audiences or pursue its own unrelated purposes. It informs the customer if an instruction appears to infringe applicable data-protection law and pauses that instruction pending clarification. If law requires other processing, SeatHarmony informs the customer before processing unless that law prohibits notice. Own account, security, billing, support and optional campaign processing are separately described in the privacy notice.
12. Security, assistance and return of data
SeatHarmony limits authorised access to service delivery and necessary support/security work. Authorised people are bound to confidentiality. Measures include encrypted transport, provider-managed encryption of cloud data at rest, account ownership and app-integrity checks, server-side permission and mutation validation, separation of service environments, protected secrets, bounded uploads and AI authorisation, processing that remains tied to the correct account, restricted operational logging, and retryable deletion barriers. Local device protection remains the customer's responsibility. Security measures are reviewed and adapted without materially reducing the agreed protection.
Taking account of the nature of processing and the information available, SeatHarmony assists with data-subject requests, security obligations, breach assessment, impact assessments and prior consultation. It forwards requests relating to customer-controlled content to the responsible customer and does not disclose that content to another requester without authority or a legal obligation. It notifies the customer without undue delay after becoming aware of a personal-data breach affecting that customer's instructed processing, supplying available facts and further information as it becomes available.
SeatHarmony makes information needed to demonstrate compliance with these processing terms available and permits and contributes to proportionate audits, including inspections, by the customer or its mandated auditor. The parties coordinate scope, confidentiality, security and timing; those arrangements do not remove statutory audit or supervisory-authority rights.
At the customer's choice, SeatHarmony returns available instructed data through export/retrieval or deletes it when the service ends or on a valid instruction, unless law requires retention. After return at the end of processing, SeatHarmony also deletes its remaining copies through the disclosed cleanup and backup-expiry processes unless law requires retention. Existing retained data can be retrieved after paid access ends, subject to the disclosed 180-day cloud inactivity policy. Standard in-app exports and printing require active Planner Plus; this does not limit the data-return obligation described here. Account or plan deletion starts guarded, retryable cleanup. Deletions of synchronized account plans propagate through synchronization; conflicting unsynchronized changes require review. Device-only plans and exported copies are not erased remotely. Expired recovery copies and provider backups follow the separate schedule in the privacy notice, remain protected and are not restored into active use contrary to an erasure instruction. SeatHarmony explains any legally required retention and confirms completion or outstanding retention on request.
13. Subprocessors and international transfers
The customer gives general written authorisation for Google/Firebase cloud infrastructure and paid OpenAI or Google Gemini analysis, OpenAI or Google Gemini audio transcription when selected, and Google Workspace where a support request contains instructed personal data. The current recipients, purposes, published location/subprocessor registers, provider retention and transfer safeguards are identified in the privacy notice. RevenueCat receives account and purchase evidence for commerce, not the ordinary guest plan; Apple and Google stores also perform their own processing under their separate contracts.
Before adding or replacing a subprocessor for instructed customer content, SeatHarmony directly notifies the customer's registered contact in advance, normally at least 14 days before the change. The customer can object on substantiated data-protection grounds during that period. The parties seek an appropriate alternative or end the affected processing before the new provider receives that customer's data; silence is not permission to disregard a notified objection. SeatHarmony imposes equivalent data-protection obligations on subprocessors and remains responsible for their performance of those obligations.
Transfers requiring safeguards use an applicable adequacy decision or appropriate contractual safeguards and assessment. No EEA-only processing or blanket zero-retention arrangement is promised. The customer can request the applicable safeguards and further processing information at admin@seatharmony.net. These processing terms prevail over conflicting general service terms for instructed personal data; mandatory law remains unaffected.
