AI usage

• Nano Banana Pro Edit (Google Gemini family, served by fal.ai) — the default image-edit model. Handles food, plate, surface, and lighting in a single pass.
• GPT Image 2 Edit (OpenAI, served by fal.ai) — instruction-following alternative.
• Seedream 4.5 Edit (ByteDance, served by fal.ai) — wider-framing alternative.
• Gemini Flash vision (Google, direct) — used by the optional "Suggest settings from photo" button and the dish-critique helper, when a Gemini key is configured (with a fal.ai-served fallback otherwise).

• Your dish photo — uploaded as a URL pointing to our Vercel Blob storage. The model fetches it directly.
• Brand-kit reference photos (when active) — your saved plate and surface reference images, sent alongside the dish photo so the model can match them.
• The rendered prompt — a text instruction describing the lighting, plate, surface, and target look. Built server-side from your style and brand-kit selections.
• A seed value — a deterministic integer that stabilises the output. Brand-kit seed takes precedence over the batch seed, which takes precedence over a random per-job seed.

We do not send your email, full name, payment data, or any other personally identifying field to any AI model.

• fal.ai — inputs and outputs are processed ephemerally. We fetch the output URL back to our own storage immediately after generation; fal.ai retains a short-lived copy per their published retention policy.
• OpenAI (for the optional suggest-settings button) — single API call per click; OpenAI's zero-data- retention API endpoint is used where available.
• Our storage — the dish photo you upload and the rendered AI output both live in Vercel Blob, tied to your user id. Deleted on account deletion.

All AI providers we use contractually agree not to train their models on data submitted via their API. This is a standard term in fal.ai's and OpenAI's API terms; consumer-product terms (e.g. ChatGPT, Gemini app) do not apply because we never use those consumer products.

We also do not train any in-house models on your photos. We never sell, rent, or share your uploaded photos with any third party other than the AI provider that renders them.

Every photo we render carries two machine-readable AI markers, embedded in the file itself at generation time (Regulation (EU) 2024/1689, Article 50 — "marked in a machine-readable format and detectable as artificially generated"):

• EXIF (IFD0) — Software ("PlateRefresh AI / Nano Banana Pro"), ImageDescription (contains "AI-assisted food photography…"), and Copyright (contains "AI-generated content").
• XMP (IPTC Extension) — Iptc4xmpExt:DigitalSourceType set to http://cv.iptc.org/newscodes/digitalsourcetype/compositeWithTrainedAlgorithmicMedia (the IPTC standard marker for a real photograph edited with a trained model), plus a dc:description note: "Edited with AI (relighting/background) — PlateRefresh".

Any standard metadata reader (e.g. exiftool) surfaces both. Note that some platforms strip metadata on upload — the Article 50 obligation is met at the point of generation.

Full C2PA cryptographic provenance is a separate, deferred workstream — it requires a signing certificate; no fal.ai endpoint currently accepts a C2PA signing flag.

Deleting your account permanently removes every photo you have uploaded, every AI output we have generated, and the prompts + seeds we kept for traceability. The deletion cascades through our database and storage layers; AI providers' short-lived copies expire per their retention policy after that.

You can delete your account from account settings at any time.
