Privacy & your data
AMVIA / amvia.ai · Updated October 14, 2026
AMVIA is part of the MADICE / KIROSTONE shared-account services. This notice covers the AMVIA website and iPhone app. The app initially launches in the United States; interface languages do not change account or privacy protections.
Information we process
Account email, display name, password verification data and consent records; uploaded room photos or other images; your descriptions and creative instructions; generated artwork, room analysis, saved placement and frame choices; support requests; transaction and fulfillment details; and limited device, network and security logs. We use these to provide, secure and support the features you request. We do not sell personal information to advertisers.
Space analysis and personalization
We save the results of analyzing your uploaded room photos, including wall areas and proportions, perspective, lighting, materials, furniture and room mood, with your account project. These are estimates inferred from the photo, not confirmed physical measurements. We link your artwork choices, feedback and saved preferences to your account to personalize suggestions and future creations. Saved creation records may include the space features and design choices used for a work. These records do not make your private room public.
Service performance and diagnostics
We record AI operation and model/provider information, processing time, request identifiers, completion or failure status, and technical errors to operate the service, investigate failures and maintain reliability and security. These records can be linked to your account or project through the request. Service providers may retain operational logs or backups under their own policies; we do not promise zero logging or immediate deletion throughout every provider system.
AI processing — before you send content
OpenAI receives photos, artwork and related descriptions when needed to analyze a space, generate or revise artwork, or produce artwork information. fal.ai provides the Topaz upscaling service for high-resolution artwork: the artwork and requested output specifications are sent for that purpose. The App asks for your permission before these AI operations. Declining does not upload your content for that operation. You can withdraw permission for future AI operations in the App account settings.
Only upload content you have the right to use. Avoid including unnecessary personal or sensitive information. These providers process content under their own service and privacy terms; deleting an AMVIA account does not promise instantaneous erasure from a provider’s legally required logs or backups.

Other service providers
Cloudflare hosts our service and stores operational data and files. Stripe processes payments made through Stripe checkout and receives the details required for checkout, billing and fraud prevention. If you order a physical product, the selected production, delivery and installation providers receive the artwork, specifications and contact or delivery details needed to fulfill it. Apple handles any App Store account and purchases made through Apple. We do not store full payment-card numbers.
Delivery and hanging address checks
When you request a delivery or hanging quote, we send the street address (line 1), city, state and ZIP code you entered to the U.S. Census Bureau Geocoder to match the address and calculate our service distance. We do not send your recipient name, email or apartment/suite field (line 2) in this lookup. The service returns a matched address and coordinates; we use the coordinates to calculate distance and save the matched address and service distance with the order details for coverage and pricing. This is an address-location lookup, not identity verification or a guarantee of postal deliverability. See the Census Geocoder and Census privacy information.
Support correspondence
When you email stone@madice.com, we and our business email provider process your sender address, message, attachments and any account or order details you choose to include to respond to questions, resolve problems and support order fulfillment. Include only what is needed; never send passwords, full card numbers or private deletion receipt tokens. Support correspondence is subject to the applicable account, fulfillment and record-retention rules below, rather than a promise of zero retention.
Sharing and access
Your uploaded room photos and account projects are private unless you explicitly share them. Sharing an artwork publishes that work, not its original room photo. You can still view your own original space when signed in. Only explicitly sharing a space makes its selected room photo and artwork available to others; it does not publish your entire account. People may retain copies of content you previously made public. Our providers may process data in the United States and other locations where they operate.
Delete your account
Open the dedicated account deletion page. Sign in, review the shared-account impact, re-enter your password and confirm. This deletes personal account data, room photos, artwork, public shares, preferences and linked private media, and revokes sign-in sessions. The shared login and Credits also serve MADICE ID, Stone Match, Stone Music, Stone Flow, KIROSTONE creation services and any linked The Light of Humanity identity. You will lose access across those linked services. Unlinked accounts are not selected by matching a name or email.
We record the request and provide a private status receipt. Processing normally starts immediately and is targeted for completion within 30 days; temporary failures are retried. The status page reports completion only after cleanup succeeds. Web subscriptions are canceled as part of deletion. For subscriptions billed by Apple, use Apple’s subscription settings as well. Deletion does not automatically refund prior purchases or unused Credits.
Retention and backups
We retain the minimum transaction, tax and dispute records for 7 years. Records necessary for an unfinished order are retained through fulfillment, then for 7 years. Any artwork needed to finish an order remains restricted to that fulfillment purpose until it is no longer required. These records do not provide a usable account or retain its password. We keep restricted deletion markers; any restoration from backup must reapply recorded deletions before data is returned to service. Historic backup copies are isolated from ordinary use and subject to controlled retention and deletion; they are not promised to disappear immediately when an account is deleted.
Your choices and contact
You can change saved information, remove shared content and request access, correction or deletion. For privacy questions or a failed deletion request, contact stone@madice.com and include the deletion request ID if you have one. Never send a password or receipt token by email. Visit support.
