Draft, pre-launch

Privacy

Hem & Grain is a pre-launch preview. This policy describes how uploads and saved previews work today.

Your photo

When you request a drawing, the site resizes your photo on your device and sends that copy to Google’s paid Gemini API for automated screening and drawing. Hem & Grain does not keep the uploaded photo. Google does not use paid API uploads to train its models and may log them for abuse prevention.

We enforce upload limits using a daily keyed hash of your IP address. The preview database keeps usage counts and removes expired counters as new requests arrive.

What we do not collect

The public preview runs no ad pixels. Saved previews and your bag stay in this browser. A saved preview keeps the drawing and its settings. Discard a preview from the bag to remove that draft.

Payments

Stripe handles payment and collects payment and shipping details. Private test checkout uses sample drawings and fictional shipping details. The private order record keeps the exact approved drawing and its fingerprint. Stripe receives the order reference and catalog items.

When Meta Pixel is enabled for private testing, it measures checkout starts and confirmed test payments. Meta receives the test amount, currency, an event identifier, the browser’s IP address and browser information. Photos, artwork, personalization and shipping details stay out of these events.
