How BabyLumi works

What you give us

Two photos of adult faces — usually yours and your partner’s — or a portrait from our catalogue of historical figures. That is all. No DNA, no medical history, no questionnaire.

Before anything is uploaded you tick a consent box for each photo, and an automatic check refuses pictures of minors or explicit content.

What the AI actually does

Three steps, none of which involves genes.

• A vision model looks at each photo and describes what is visible: eye colour, hair colour and texture, skin tone, face shape.
• A simple textbook-style inheritance model mixes those two descriptions into a plausible combination — the same kind of chart you may remember from school biology, with a little randomness so every run differs.
• An image model paints a child from that description, in the age and style you chose. The picture is drawn from scratch; nothing is “morphed” from your faces.

Why it is a fantasy, not a prediction

Real inheritance involves thousands of genes, and a photo only shows what is visible — not what someone carries. The image model invents a believable face rather than computing a true one: run the same photos twice and you will get two different children.

Treat it the way you would a portrait artist’s guess: charming, sometimes uncannily close, never evidence of anything.

Where your photos live

Uploads and results are stored encrypted in Cloudflare R2 under EU jurisdiction, and are deleted automatically:

• free previews — within 24 hours;
• paid results — after 30 days;
• we never use your photos to train AI models, and neither may the model providers we call (see the sub-processor list in the Privacy Policy).

Who can see the result

You, and anyone you send the link to. Result links are private, unguessable and marked as not-for-search-engines. Nothing appears in a public gallery unless you post it there yourself.

What you control

• “Download my data” in the profile menu gives you a zip with every photo, result and record we hold.
• “Delete account” erases photos, generations and videos within a minute. It cannot be undone.
• Anything else: [email protected].
