Provider transparency
Subprocessors and Data Providers
Last updated: July 23, 2026
This page identifies the external services evidenced in the current Peakstar release that may process data for an enabled connection or user-started task.
How this list works
A provider receives data only when its related feature is configured and used. Amazon is listed as the seller-connected data platform; the remaining services support storage, model processing, or a specific image workflow. Peakstar does not infer or list a payment processor that is not part of the current application release.
Amazon (Selling Partner API, planned Amazon Ads API, and optional Amazon SQS)
Purpose: seller-authorized Amazon marketplace access, planned separately authorized Amazon Ads access if approved, and lifecycle notifications when configured. Data can include OAuth authorization, seller, advertiser, profile, and marketplace identifiers, plus the product, listing, inventory, order, fulfillment, financial, reimbursement, review, analytics, campaign, targeting, budget, bid, search-term, or advertising-performance data required by enabled features. Amazon is the connected platform and source of this data, not a generative AI provider.
Contabo GmbH
Purpose: infrastructure hosting for Peakstar-operated application, database, email, monitoring, and security services. Data can include encrypted or access-controlled service data processed within the hosted infrastructure as required to operate Peakstar.
Backblaze B2
Purpose: managed object storage for seller-selected product and reference assets, generated images, thumbnails, and delivery or publication assets. Data can include image files and tenant-scoped object paths.
KIE AI (api.kie.ai)
Purpose: configured research, planning, rewrite fallback, and model job processing. Data can include creative prompts, task settings, and seller-selected reference asset URLs or images when the seller starts the applicable creative task.
Google Gemini API
Purpose: configured fallback research and file processing for supported creative workflows. Data can include creative prompts and seller-selected reference assets when that fallback is used.
fal.ai
Purpose: layered-image processing for the Layered Upscale workflow. Data can include the seller-selected image URL and the parameters needed to run that task.
Current AI data boundary
The current release does not send Amazon operational metrics, Brand Analytics metrics, or Amazon Ads performance data to KIE AI, Google Gemini, fal.ai, or another generative AI service. A seller-selected product asset may be sent to the applicable provider only after the seller starts a creative task that needs it.
Peakstar-operated services
Peakstar operates its Postgres data service and Mailcow email service on the infrastructure listed above. These are Peakstar-managed service components rather than separate SaaS providers.
Questions and changes
Provider use can change as features change. Peakstar will update this page before intentionally introducing a new provider for these data-processing purposes. Questions can be sent to yunus@peakstar.ai.
