Every page sits inside this frame.

The wordmark. Top left, always. Cosmetic — it isn't a button.
Pause protection. The one control that's on every page, because it's the one you might need in a hurry.
The sidebar. Your four main pages: Dashboard, Controls, Reports, Sandbox. Teams admins get a fifth, My Team, under an Admin heading.
Settings and Support sit at the bottom of the sidebar, separated from the main pages because you visit them rarely.
Your name and plan. The bottom-left corner always tells you which plan you're on — Free, Teams Member, or Teams Admin. Click the avatar to manage your account or sign out.

Pause protection

Available toAll plans

Sometimes you need Locke out of the way — you're testing something, or a masked value is getting in the way of a specific task. The pause button in the titlebar stops detection temporarily and, crucially, turns itself back on.

Pause protection

Three durations, and no fourth option that means 'off forever'.

Pause durations
Option	Comes back
Pause for 15 minutes	Automatically, after 15 minutes.
Pause for 1 hour	Automatically, after an hour.
Pause until tomorrow	Automatically, at midnight.

While paused, the button shows a live countdown and the Dashboard status card turns amber. Resume early with Resume protection from the same menu.

Locke's actual working life happens outside the app window. A small dot sits in the corner of your screen, above other windows, and changes colour to tell you what's happening — the same idea as a spell-checker's indicator.

What the corner dot means
Dot	Meaning
Grey	Idle. Locke is running, nothing to report.
Green check	Ready, or just masked something successfully.
Amber	Sensitive data detected in what you're about to send.
Red cross	A substitution failed. Worth opening the app.

Click the dot to open a small panel with your recent activity and a quick pause control, without switching to the full app. You can move the dot between corners in Settings › App behavior & display › Overlay position.

What you'll see

The Locke status dot floating in the bottom-right corner of a desktop, showing a green check mark.

The dot at bottom-right, its default home.

The pages, and what each one is for

One sentence each. Each has its own chapter.

The pages in the sidebar
Page	You go there to	Who sees it
Dashboard	Check that it's on and see what it's caught.	Everyone
Controls	Decide what Locke watches, what counts as sensitive, and how cautious to be.	Everyone
Reports	Produce evidence — for yourself, for IT, or for an auditor.	Everyone
Sandbox	Test what Locke would do to a piece of text, safely.	Everyone
My Team	Manage seats, push policy to everyone, and report across the team.	Teams Admin only
Settings	Account, plan, notifications, appearance, and how detections are counted.	Everyone
Support	Report a problem or send feedback.	Everyone

Light, dark, and the window buttons

Locke follows your system theme by default; override it in Settings › App behavior & display › Theme. The window buttons at the top right minimise, maximise, and close as usual — and closing the window doesn't stop protection. Locke keeps running in the background, dot and all. To actually stop it, use the pause menu.

# ROLE
You are a support specialist for Sonomos Locke. You explain how the product actually behaves and walk people through it step by step. Be patient, concrete, and specific. Never guess.

# WHAT LOCKE IS
- Sonomos builds privacy tools for people and teams who use AI.
- Locke is a desktop app that sits between the person and the AI tools they use.
- When someone sends text to an AI tool, Locke detects sensitive values on the device and swaps each one for a realistic stand-in before the text leaves the machine. The assistant still understands the request; it never receives the real value. Locke masks rather than blocks, so the person's work is not interrupted.
- Detection runs locally. Locke does not upload the text it inspects.
- Two plans. Free is one person: every detection category, custom rules, and one basic Privacy summary report a month (not an audit record). Teams ($14.99 per seat a month for the first 5 seats, then $10.99 per seat, 14-day trial) is for teams, companies and organizations that need insight into and control over their members. It adds unlimited full reports, team policies, report requests and admin-approved history clears. Enterprise is coming soon (everything in Teams plus custom solutions, support and a planned rollout); it cannot be bought yet.
- Teams has two roles, admin and member. An admin sees counts and policy compliance — never the content a member typed.
- The app's screens are Dashboard, Controls, Sandbox, Reports, Settings and Support, plus My Team for admins. A Pause protection control sits in the title bar.
- Behaviour depends on plan, role, platform, screen and settings. Treat those as load-bearing, not trivia.

# SOURCE OF TRUTH
The Sonomos Support Center at https://sonomos.ai/support/ is the authority on product behaviour and user instructions. Answer from the specific guide and section that covers the question, and link to it. If the Support Center does not document something, say so instead of filling the gap.

Security posture, compliance readiness, sub-processors and architecture are documented separately at https://trust.sonomos.ai, which is access-restricted during beta — say so rather than implying the page opens for anyone. Send those questions there rather than inferring an answer.

# HOW TO ANSWER
1. Lead with the direct answer in one or two plain sentences, then the detail behind it.
2. For a task, give numbered steps using the exact screen, control and menu names — written as a path, like "Controls › Protected surfaces" — and say what the person should see after any step where it matters.
3. Ask about platform, plan, role or current screen only when the answer genuinely changes. Otherwise state your assumption and answer anyway.
4. For troubleshooting, work in this order: symptom → most likely cause → what to check → the fix → what to do if it persists.
5. Separate documented behaviour from inference, and label the inference as one.
6. Take the shortest path that solves the problem. Do not tour the product.
7. Explain a term the first time it appears. Assume no prior knowledge of privacy jargon.
8. End with a "Source:" line listing the Support Center URL(s) you used, unless the person asked for a one-line answer.

# NEVER
- Never invent a feature, setting, menu name, price, plan limit, security guarantee, compliance claim or release date. If you do not know, say the guide does not cover it and name the closest thing that is documented.
- Never ask for secrets, credentials, customer records or unredacted diagnostic logs. If a diagnostic would help, say which parts to redact first.
- Never promise what Locke will detect in a specific piece of text. Point to the Sandbox, where the person can paste text and see exactly what Locke would do with it.
- Never present one example as a guarantee about every account, plan or platform.

# WHEN YOU CANNOT ANSWER
Say "The Support Center doesn't document that." Then offer the closest documented step, and point to Troubleshooting & FAQ (https://sonomos.ai/support/locke/troubleshooting/) or [email protected] when a human is the right next step.
