TACENZA.
Brand guidelines · a CARTIQO. product
TACENZA is a private messenger: an account is only a username and a password, and everything is encrypted before it leaves the device. The brand should feel the same way – quiet, precise and honest. These guidelines cover the logo, colour, type, interface and voice.
Logo
The wordmark is TACENZA. set in Bodoni Moda Bold, all capitals, with the full stop in the accent colour – the same treatment as CARTIQO. The full stop is part of the name: never leave it out, and never colour it anything but the accent. In running text, write the name as TACENZA – in capitals, without the full stop and in the regular text face: “TACENZA Chat”, “TACENZA is free”. The full stop belongs to the logo and to the endorsement line “TACENZA. is a CARTIQO. product.”
Lockup with endorsement
Use on the landing page, in the footer and anywhere TACENZA introduces itself.
App mark
“T.” for app icons, favicons and avatars, where the full name won't fit. Dark is the default.
One colour
For print, engraving and anywhere only one colour is possible. The full stop takes the same colour as the name.
On the accent
On the accent colour, use the white version – never the accent full stop on itself.
Clear space
Keep clear space around the logo equal to the width of its T on every side (marked x). No text, edges or other logos inside it.
Minimum size
| Wordmark on screen | 96 px wide |
| Wordmark in print | 20 mm wide |
| App mark on screen | 16 px |
| Lockup (endorsement readable) | 180 px wide |
Below these sizes, use the app mark instead of the wordmark.
Don't
Stretch, squash or rotate it.
Recolour the name or the full stop.
Drop the full stop from the logo.
Set it in another typeface.
Add shadows, outlines or effects.
Place it on busy images or gradients.
Colour
A quiet, violet-tinted palette. Neutrals lean towards the accent so nothing looks default, and the accent is used sparingly – for the full stop, primary actions and links. The app has a light and a dark theme; both are designed, not inverted. Click a value to copy it.
Light theme
Dark theme
Contrast
Every text colour meets WCAG 2.1 AA (4.5:1) on the grounds it's used on; the app tests this on every build.
| Pair | Light | Dark |
|---|---|---|
| Ink on background | 14.0 : 1 | 15.3 : 1 |
| Ink on surface | 16.6 : 1 | 13.9 : 1 |
| Muted on surface | 5.4 : 1 | 6.5 : 1 |
| Accent on surface | 9.2 : 1 | 6.5 : 1 |
| Button text on accent | 9.2 : 1 | 7.1 : 1 |
| Danger on surface | 7.4 : 1 | 7.0 : 1 |
| OK on surface | 5.2 : 1 | 9.2 : 1 |
| Warning text on warning ground | 7.7 : 1 | 9.9 : 1 |
Typography
Two families: a high-contrast Didone for identity, and a typeface designed for legibility for everything people read and tap. Both are open source and self-hosted – TACENZA never loads fonts from a third party.

Weights 500 and 700. For the wordmark, headings, safety-number digits and avatar initials. Never for body text or buttons.
Text · Atkinson Hyperlegible
Just a username and a password. Designed by the Braille Institute so that easily confused letters – I l 1, O 0 – stay distinct.

Weights 400 and 700. For everything else: messages, labels, buttons, settings.

Components
The interface is calm and flat: one accent, rounded but not pill-shaped, borders instead of shadows. These are the app's own styles and change with the theme.
Buttons
One primary action per view. Danger buttons are outlined; they fill only in the final confirmation.
Fields and switches
Protected contentChat
Badges, notes and safety numbers

Icons
Line icons on a 24 px grid, 2 px stroke, round caps and joins, drawn in the current text colour. No filled icons, no emoji as icons, and every icon-only button has a text label for screen readers.
Voice
TACENZA talks like a calm, knowledgeable friend: plain, short and honest about limits. It never promises more privacy than it can deliver.
- Plain words. Say what happens, from the user's side: “Only you and the people you write to can read it”, not “E2EE with ECDH P-256”.
- Honest about limits. If something can't be done – a web page can't block screenshots – say so.
- Sentence case everywhere, including buttons and headings. Only the name TACENZA and the wordmark are in capitals.
- No exclamation marks in errors. Explain what went wrong and what to do next.
- English and Danish at launch, written for each language – never machine-translated.
Nobody can reset your password for you – not even TACENZA – because nobody else can open your account. Use the recovery key your device made when you signed up.
Your device couldn't work out where it is. Turn on location in Windows Settings.
Military-grade, 100% unhackable encryption!

Screenshots and imagery
- Show the product in use with example people – Anna, Ben, Chloe – and example content. Never real names, faces, messages, addresses or documents, not even blurred.
- Use real app screens at their true size; don't mock features that don't exist.
- Photography, when used, is quiet and unposed: interiors, hands, daylight. No stock images of padlocks, hackers or binary code.
