4.1 To operate the platform: creating your account, processing your generations, managing your subscription and credits.

4.2 To process payments via Stripe. We pass your email and subscription details to Stripe for payment processing. We never store your full card details.

4.2a If you connect a Stripe account to sell from a published site. Selling through a site you publish is optional and off unless you set it up. If you do, you connect your own Stripe account through Stripe's own hosted onboarding, and we never see or store your Stripe login. When you provide personal data in connection with connecting that account, Stripe receives that personal data and processes it in accordance with the Stripe Privacy Policy. We store your Stripe account identifier and the order records for sales made through your site (including the buyer's email and what they bought) so we can show you an orders inbox and keep your stock counts right. We never receive your customers' card details, and we never hold their money.

4.3 To send you essential service emails: receipts, subscription confirmations, credit alerts, security notices. You cannot opt out of these as they are necessary for the service.

4.4 To send you marketing communications: product updates, new features, blog posts. Only with your consent. You can unsubscribe at any time via the link in every email.

4.5 To improve the platform. We analyse aggregated, anonymised usage patterns (which models are popular, average generation times, error rates) to improve the service. This analysis uses only aggregate statistics. Your individual prompts, uploads, and outputs are not used for this purpose.

4.6 To prevent abuse. We monitor for violations of our Acceptable Use policy and may review flagged content.

5.1 Images, audio, video, and other files you upload, and prompts you submit, are processed solely to fulfil your generation requests. They are transmitted to the relevant third-party AI model provider for processing and then returned to us.

5.2 We do not use your uploads, prompts, or generated outputs to train AI models. This applies to everything you create on ArchAdemia Tools, without exception and regardless of your plan. We do not train models of our own, and we do not supply your work to anyone else for that purpose.

5.3 Generation runs on third-party model providers. We do not operate the AI models ourselves. To produce an output, your inputs are passed to the relevant provider, processed on their infrastructure, and returned to us. Each provider operates under its own terms, which govern what it may do with content passing through it. Those terms are the provider's and not ours, and we cannot vary them on your behalf. Our access is governed by B2B agreements between Archademia Ltd and each provider; under some of those agreements a provider may retain or use inputs and outputs for its own purposes, including model training and improvement. That is a separate question from our own commitment in 5.2, which is unaffected.

Provider terms at a glance

• fal.ai retains generated media on their CDN for a limited period (typically 7 days) before deletion.
• EvoLink (the gateway that routes Seedance requests onward to ByteDance) does not publish specific input-retention or model-training terms; the Seedance models themselves are operated by ByteDance (see Section 12).
• Runway reserves the right to use inputs and outputs for model training on non-Enterprise API plans.
• Kling (Kuaishou) retains a permanent, royalty-free licence to use content for AI training and promotional purposes.
• ElevenLabs retains a perpetual licence to create derivatives from voice data for model improvement.

These summaries are a guide, not the providers' terms, which may change at any time. Current terms and privacy policies for every provider are linked at archademia.tools/providers.

5.4 Generated outputs (images, videos, audio, 3D models) are stored on our own infrastructure (Supabase storage). When a provider returns a generated file, we download it to our storage. The provider's temporary copy typically expires within hours to days depending on the provider.

5.5 You can delete generated content at any time from your dashboard. When you delete content, it is removed from our storage within 30 days to allow for backup cycle completion. Orphaned temporary files are automatically cleaned up by a scheduled maintenance process. If your account is on the free trial and does not upgrade before the trial ends, your generated outputs are automatically deleted from our storage 30 days after the trial ends (see the retention table in Section 9); your account and generation history are not affected.

5.6 Generated output URLs. Your generated files are stored in our storage using unique, non-guessable file paths. Files are accessible via direct URL without additional authentication, which enables features such as sharing and embedding. However, file paths cannot be listed or enumerated by other users. Access requires knowing the exact URL.

5.6A Export metadata. Files you export from ArchAdemia Tools, including PDF drawings and sheets, DXF files, Layout documents, Corb handouts, and documents you export from Research, Writing and Canvas, carry your account identifier in their file metadata. It is the opaque identifier your account is known by in our database, and it is the only thing we add: never your name, never your email address, never your IP address, and never your location. It is metadata, not a watermark. It is invisible on the drawing, it does not print, and it has no effect on the drawing itself or on the scale it plots at. We include it so that a leaked or redistributed file can be traced back to the account it came from. In a PDF you can see it, and remove it, under the document properties in any PDF editor. In a DXF it is written as a comment at the very top of the file, which you can read or delete in a text editor.

Essential cookies: Required for the platform to function, including authentication and session management. These cannot be disabled.

Analytics cookies: Help us understand how the platform is used. You can opt out of these via the cookie banner on first visit.

Right of access: Request a copy of all personal data we hold about you.

Right to rectification: Request correction of inaccurate data.

Right to restrict processing: Request that we limit how we use your data.

Right to data portability: Request your data in a structured, machine-readable format.

Right to object: Object to processing based on legitimate interests or for direct marketing.

Right to withdraw consent: Where processing is based on consent, you can withdraw it at any time.

12.1 Data Transmitted. When you use Seedance, the following data is sent to EvoLink and ByteDance for processing:

• Your text prompt
• Any reference files (images, audio, video clips) you include
• Any video you supply for editing or extension (Seedance 2.5 video-edit and video-extend)
• A unique end user identifier linked to your ArchAdemia Tools account
• Generation parameters (resolution, duration, aspect ratio, audio settings)

12.2 Data We Log. In addition to the data transmitted, ArchAdemia Tools logs: timestamps, generation status, error categories, and the EvoLink task ID for each Seedance generation.

12.3 Processing Chain.

• ArchAdemia Tools (United Kingdom): data controller
• EvoLink, operated by EVO GLOBAL TECHNOLOGIES LIMITED (Hong Kong): data processor, routing generation requests
• ByteDance (China): sub-processor, running the Seedance models

This chain is specific to Seedance. Other models on ArchAdemia Tools involve different processors (see Section 6).

12.4 Purpose. Prompts, references, and parameters are processed solely to generate the video content you requested. The end user identifier is required by our distribution agreement for user identification and compliance. Generation logs are maintained to comply with identification and restriction requests if required by ByteDance or EvoLink.

12.5 Retention. Generated video URLs expire within 24 hours on EvoLink's infrastructure. Seedance generation logs are retained by ArchAdemia Tools for a minimum of 12 months.

12.6 Your Choice. You are not required to use Seedance. All other video, image, 3D, audio, and writing models on ArchAdemia Tools remain available without the data processing described in this section. If you do not wish your data to be processed by ByteDance, simply choose a different video model.
