Thumbkiss
brand assets
The official home of the Thumbkiss logo and design system. Thumbkiss is a private couple app for two people. Its mark is a fingerprint drawn as a heart, because a thumbkiss is what happens when two people press their thumbs to the same spot on a screen.
Everything here is free to download for press, app directories, review sites, creators and partners. Take the whole kit, or grab a single file.
01 The mark
Logo
A single continuous line that spirals like a fingerprint and closes into a heart, drawn on a 512 × 512 grid with a uniform stroke and rounded terminals. Red is the default. White is for photography, video and dark surfaces. Black is for single colour print.
02 Logo with text
Lockups
Use a lockup where the symbol alone would not be recognised: app stores, press articles, partner pages, sponsor walls. The wordmark is set in General Sans Semibold at −1.2% tracking and drawn as outlines, so it never depends on a font being installed.
Reach for the two tone horizontal version by default. Switch to single colour when the layout already carries another accent, when you print in one ink, or when the logo sits beside other partner logos. Use the stacked version only in roughly square space.

Stacked and wordmark
03 Share it
Badges
If you build something with Thumbkiss, use it with your partner, or write about it, these are yours. Put one on a screenshot, a photo, a story, a website footer or a README. Eight messages in four shapes, each in four styles: dark, light, Thumbkiss Red and a white outline that sits on any photo.
Pill
Sticker
Square stamp
Chip
All 76 badges, stickers, stamps and chips are in the kit. Link them back to thumbkiss.app wherever the medium allows links, and please do not edit the text or make your own variation.

04 Product
App icon
The icon that ships on the App Store and Google Play. Do not add your own rounded corners to the 1024 × 1024 master, because iOS and Android apply their own mask. Thumbkiss also ships alternate in app icons (Default, Gold, Diamond, Legend, Premium, LDR). Those are product features, not public brand assets.
05 Construction
Clear space
Keep a clear margin around the logo equal to 25% of the mark height on every side. Nothing enters that margin: no text, no other logos, no photo edge, no interface chrome.
| Context | Minimum size |
|---|---|
| Symbol on screen | 24 px height |
| Symbol in print | 8 mm height |
| Horizontal lockup on screen | 96 px width |
| Horizontal lockup in print | 28 mm width |
| Stacked lockup on screen | 64 px width |
| Pill badge on screen | 28 px height |
| Favicon or avatar | Use the red tile |
Below 24 px the inner spiral fills in. If you need the logo smaller than that, use the red tile, which is drawn to survive it.
06 Rules
Do and don’t
Do
✓Use the SVG whenever the medium supports it. It stays crisp at every size.✓Use white on any background darker than 40% luminance, and on photography.✓Scale from the corner, with the aspect ratio locked.✓Keep 25% of the mark height as clear space on all four sides.✓Write the name as “Thumbkiss”. One word, capital T, no space, no hyphen.
Don’t
✕Recolour the mark. Red, white or black only. No gradients, no pink.✕Add drop shadows, outlines, bevels, glows or strokes.✕Stretch, squash, rotate, skew or distort the logo.✕Rebuild a lockup, change the gap, or set the wordmark in another typeface.✕Place red on a red, pink or busy background where it loses contrast.✕Use the logo to imply that Thumbkiss endorses or sponsors you.

Palette
Thumbkiss Red is the one colour that has to be right. Everything else is a supporting neutral. Click a swatch to copy its hex.

#080604#0F0C0C#0B0A0A#5A5560#8A8590#FFFFFFRed on white needs care
Thumbkiss Red on white measures 3.63:1. That passes WCAG AA for large text at 24 px
and up, for icons and for component borders, but it fails for body copy. On a light background, set links and
small text in Red 600 #E31048 at 4.74:1 or
Red 700 #BE0A3D at 6.36:1. On the dark
Thumbkiss background, red measures 5.44:1 and is safe everywhere.
| Pair | Ratio | Verdict |
|---|---|---|
#FF2E57 on #FFFFFF | 3.63:1 | Large text, icons, borders |
#E31048 on #FFFFFF | 4.74:1 | AA for all text |
#BE0A3D on #FFFFFF | 6.36:1 | AA everywhere, AAA large |
#FFFFFF on #FF2E57 | 3.63:1 | Large text and buttons |
#FF2E57 on #080604 | 5.44:1 | AA for all text |
#FFFFFF on #080604 | 20.23:1 | AAA |

Spacing runs on a 4 px base. Radii are named by role rather than by pixel value, so a component keeps its personality when it is resized. Copy the CSS below, or take the tokens JSON.

What does the Thumbkiss logo mean?
It is a fingerprint drawn as a heart. A thumbkiss happens when two partners press their thumbs to the same spot on their screens and both phones respond. The mark fuses the most personal thing a person has, their fingerprint, with the shape of the feeling behind it.
