Usage Guidelines

General

DO use the Signal Trademarks to refer to the associated Signal products or services. Example: An authorized developer may note in their advertisements and products that they utilize the Signal Protocol.
DO distinguish the Signal Brand Assets from any surrounding text in some way. Capitalize the first letter, capitalize, or italicize the entire mark, place the mark in quotes, or use a different font for the mark than for the generic word.
DON'T use an image confusingly similar to the Signal Brand Assets or other variation of any Signal Brand Assets for any purpose.
DON'T use or register Signal trademarks as or incorporated in social media account names, profiles, or monikers.
DON'T combine the Signal Brand Assets, or any portion of any of them, with any other logo, company name, mark, or generic terms, or in any way that implies partnership or endorsement by Signal without explicit written permission.
DON'T describe your app or product as "for Signal" when it is not integrated with the Signal platform or specifically designed to complement just the Signal app.
DON'T monetize the Signal Brand Assets, such as by using them on merchandise like toys, apparel, accessories, or packaging without explicit written permission.
DON'T use Signal or Signal Brand Assets in your domain name.

Referring to Signal and Signal users, groups, etc

Spell and capitalize the Signal Trademarks exactly as they are shown on the Signal Trademarks page. Use the Signal Trademarks as an adjective; do not use the Signal Trademarks as a noun or verb, or in a way that suggests a common, descriptive, or generic meaning.

"Send secure messages via the Signal protocol."

Using the Signal logo

Only use the official Signal Logo that is available from the Signal Brand Assets website. Do not alter or modify the logo in any way other than scaling proportionally. Keep in mind the following guidelines for using the Signal Logo:

Minimum clear space

When placing the Signal Logo near other elements, utilize a clear space of at least half (0.5x) the size of the logo around it.

Minimum size

A minimum size ensures that the impact and legibility of the glyph is not compromised in application. Always maintain their set proportions and never show the glyph smaller than 26x26 pixels.

DO maintain a minimum clear space around the Signal logo.

DO display the logo at a minimum size of 26x26 pixels.

DO maintain a minimum clear space around the Signal logo and word combination.

DON'T alter the Signal Logo by rotating, stretching, outlining, or adding effects.

DON'T modify the typography of the Signal wordmark.
