Terms of use
Who we are
Arch, by Voluta.ai, is a service of 69.337.655 GABRIEL DE CASTRO SODRE, CNPJ 69.337.655/0001-56, based in Belo Horizonte, MG, Brazil. Support: [email protected].
The service
Arch receives images of architecture and interior design projects, such as views exported from 3D software, generates realistic images from them with artificial intelligence, and builds an online presentation with PDF and PPTX exports that you can send to your clients.
Your account
You create the account with a valid e-mail and are responsible for whoever has access to it. One account is one office. You must be 18 or older. You may ask for the account to be deleted at any time, by writing to [email protected] from the account’s e-mail.
Credits and payment
Everything in Arch is counted in credits, on the free trial and on the plans: a render uses 175 credits. At top quality, when included in your plan, a render uses 225 credits. A video with a camera move uses 800 credits; when it starts from a model or an uploaded image, it adds the render made before it, 975 in total. The Construction and Furnishing videos use 400 credits and add one more image, 175 credits, plus the render when they start from a model. A photo animated as it is uses 400. Credits are reserved when generation starts and spent when the image is ready. Failed, refused or cancelled unfinished generations release the reserve. Credits of the old packs are converted: each old credit is worth 175 credits, the same as one render, and does not expire while the account exists. Courtesy credits have no cash value and are not refundable. Prices and included quality are those confirmed at checkout.
Subscriptions and renewal
Monthly charges and credit quotas renew each cycle. The annual price displayed per month is a reference: checkout charges the full 12 months, and the annual quota is released after payment confirmation and valid for 12 months. Unused credits roll over into the following cycle while the subscription renews; if it ends, they expire with the last paid period. You can cancel renewal from your account, keeping paid access until the period ends. BRL and USD payments are processed by Stripe. Card details are entered with Stripe and never pass through Arch.
Free trial
Each new account gets 350 free credits, enough for 2 images. Video comes with a plan. Those images are shown at full web quality, without a watermark, and the project’s presentation shows a preview banner and has no PDF or PPTX export. The plan releases video and original files, removes the banner and enables exports. The trial is one per person; creating accounts in series to repeat it is forbidden use. A new account of someone who already used the trial gets neither the free credits nor the free days: on signing in, it goes straight to subscribing. When the trial is repeated with other accounts, we may pause access to those accounts, their presentations and the links sent to clients until a plan is subscribed; nothing is deleted.
Refunds
The Refund policy applies and is part of these terms.
Your images and files
What you send remains yours. You authorise us to store, process and display that content only to provide the service to you: to generate the images, build the presentation and its PDF and PPTX exports, and show them to whoever has the link. You declare that you have the right to send that content and to share it with your clients.
Images generated by AI
Generated images are delivered to you for use in your projects and presentations, with no restriction on our part. They are an approximate visual representation: they may differ from the project in materials, colours, objects and proportions, and do not replace technical drawings or specifications. It is up to you to check each image before presenting it. Because they are generated by AI, we do not guarantee that they are unique or that they can be protected by copyright.
The client presentation
You decide what goes in the presentation and to whom you send it. Each send creates a fixed revision: later changes to the project reach the client only in a new revision. Each person’s link may require a code sent to their e-mail to respond or to open, as you choose, and can be deactivated at any time. The approval a client records is an acceptance with name, date, revision and, when a code was used, a confirmed e-mail; it is not a certified digital signature. No file is sent to the client: they view the presentation on our site.
Forbidden use
It is not allowed to send illegal content or content of others without authorisation, to try to generate images of real people, to get around limits or create accounts in series, to resell access, or to interfere with the service. We may suspend an account that does so, with notice by e-mail.
Limits and availability
Technical file, processing and free-trial limits are stated in the product. Each plan allows a number of new presentations sent per monthly cycle and a number of sent presentations that can be kept at once, stated on the pricing page; revisions of projects already sent do not count. Drafts have no quantity limit and expire after 60 days without an edit; when they expire, they disappear from the account and their files are deleted within 30 days. Archiving a sent presentation takes the client link offline and frees the slot; restoring needs a free slot. When you move to a smaller plan nothing is deleted: what exceeds the limit becomes read-only until you archive it. After cancellation, links stay online for 30 days and are then archived; files are deleted 90 days after cancellation, with two notices by e-mail. In the trial version, sends are delivered only to the account e-mail. We do what we can to keep the service running, without guaranteeing uninterrupted operation. Projects not accessed for 12 months may be deleted, with notice by e-mail 30 days before.
Liability
We answer for direct damage we cause, limited to the amount you paid in the previous 12 months. We do not answer for design, construction or purchase decisions made from the generated images. Nothing here removes rights the law guarantees to consumers.
Changes
We may change these terms and the prices. Relevant changes are announced by e-mail and ask for a new acceptance; credits already purchased keep the conditions of their purchase.
Law and venue
Brazilian law. The courts of the consumer’s domicile; for companies, those of Belo Horizonte, MG, Brazil. The Portuguese version of these terms prevails.
