A look is a code you can paste

What does a recipe contain?

• Face shape amounts, including Slimming → Nose, applied in proportion to each face.
• Skin: Soften and Even tone values.
• Detail: Teeth whitening and Eye brighten values.
• Light and color: Brightness, Contrast, Warmth, Saturation, Fade.
• The chosen Look and its Intensity.

A recipe never contains the crop, Heal spots, Under-eye or any body edit (Chin included). Those are tied to one photo or one person and would make no sense on another.

Proof: the recipe format lists exactly these fields; body and heal edits are excluded by design.

How to share a look

1. Finish an edit and tap Share look.
2. Copy the code, or share a link. Optionally include the photo as a separate image.
3. The other person pastes the code on the Home screen, or opens the link. Sfuma applies the look to their photo.

Pasting a code is free for everyone. Creating and sharing your own looks is part of the unlock.

Links that keep the server out of it

A recipe link looks like sfuma.cam/r/#SF-2400-CCW0. Everything after the “#” stays in your browser; it is never sent to our server. The page on sfuma.cam decodes it locally and offers to open Sfuma. If the app is installed, the link opens it directly.

Proof: the part of an address after “#” (the fragment) is never included in the HTTP request. The server only ever sees “/r/“.

Codes that last

A code is SF- followed by groups of four characters; the last group can be shorter, and an edit with more settings makes a longer code. Codes use a character set without the letters that get confused with digits, so a code typed from a screenshot comes out right. Every code starts with a format version, so later versions of Sfuma can keep reading today’s codes.

Proof: each code carries a version and a checksum, so a mistyped code is rejected rather than applied wrong; the website’s decoder is tested against codes made by the app.

Do you make looks people ask for?

A creator look is simply the code a creator’s own edit produced, like SF-24JG-CG7T-3C. Put it in a caption or a story, and anyone who pastes it gets the same look on their own photo. Nobody can pick the letters of a code: they come from the settings. If people ask you for your look, we would like to feature it and its code on Sfuma’s own channels.
