Sideline gives you a second phone number for calling and texting—so you can stay connected without sharing your real number. Get the app today to keep your personal number private. Whether you're working, selling online, or just want more control over who can reach you, Sideline makes it easy to separate your communications. FREQUENTLY ASKED QUESTIONS What is Sideline, and how does a second phone number work? Sideline is a second phone number app that lets you call and text from a separate number on your smartphone. Just download the Sideline app, and your Sideline number will work alongside your primary number, so you can keep personal and secondary communications separate without needing a second phone. Can I use Sideline for private texting and calling? Yes. Sideline is designed for private texting and calling, so you don't have to share your personal phone number with strangers and businesses. Use your second number for work, online selling, dating, or any situation where you want more privacy. Is Sideline reliable for calls and texts? Sideline uses your carrier's cellular network (not VoIP), which means your calls are clear and reliable—just like your regular phone number. You can send unlimited SMS and MMS messages and make calls with confidence. Can I choose or transfer my phone number? Yes. You can select a second phone number with an area code of your choice, or port (transfer) your existing number to Sideline. This makes it easy to keep a number you already use while gaining more privacy and features. Who is Sideline for? Sideline is for anyone who wants a second phone number to keep their personal number private and their communications organized—like professionals and business owners who don't want to carry a second phone, people buying and selling online who don't want to share their real number, freelancers who need to manage client communications—and anyone who values privacy and wants to control who can reach their real number. Do I need to provide a government-issued ID to create a Sideline account? No. You do not need to submit a government-issued ID to sign up for Sideline. Instead, you'll verify your account using two-factor authentication (2FA).

# Design Brief: Minimal Monochrome

Monochrome palette with a single accent color, hairline dividers, and generous whitespace.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f2f2f4;
  --foreground: #0c0c0b;
  --muted-foreground: #70736b;
  --accent: #00b744;
  --radius: 4px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~73%) · Surface #F2F2F4 (~4%) · Text #0C0C0B (~6%) · Muted Text #70736B (~10%) · Accent #00B744 (~7%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Download App / Install Extension
- Headline hook: Pain Relief & Replacement
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring centered headline + cta layout and photography / live video visuals.

## Avoid

- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
