Private by default.

1. What OpenBar stores

OpenBar keeps a small amount of data on your device so it can remember your preferences and recent work. All of it lives in a single file in your operating system's per-user application data folder, and none of it leaves your machine.

Screen captures and picked colors are produced on demand and held in memory or copied to your clipboard. You decide whether to copy them or save a file — OpenBar never transmits them anywhere.

2. What OpenBar never does

• It does not send your data to us or anyone else — your clipboard, screenshots, and colors never leave your machine.
• It does not include telemetry, analytics, crash reporting, or usage tracking.
• It does not require — or offer — an account, login, or subscription.
• Its only network request is the licence check: your serial activates online once, and roughly monthly OpenBar re-checks it in the background. Both requests carry your serial, an anonymous machine identifier (a one-way fingerprint derived on your machine — not your hardware details), and the app version — nothing else, ever. If the check cannot get through, OpenBar keeps working: an offline or air-gapped machine keeps working indefinitely.
• It does not sell, rent, or share your clipboard contents, screenshots, or color samples.
• It does not run in the background harvesting data; tools act only when you invoke them.

Beyond that licence check, the only time OpenBar reaches the internet is when you click the website link in Settings, which simply opens that page in your normal browser.

3. Permissions, and why they're needed

OpenBar uses a few operating-system capabilities to do its job. Each is used solely to provide a feature on your device:

• Screen capture — powers the capture tool, the color picker, and the measure overlays. Captured images stay local.
• Clipboard access — lets tools copy results out and lets clipboard history track what you copy. This data never leaves the machine, and history can be disabled or capped in Settings.
• Saving files — only ever happens through a standard "Save as" dialog, to a location you choose. OpenBar never writes files to arbitrary paths on its own.
• Launch at startup — an optional convenience you control with a single switch in Settings.

4. Built to be safe

OpenBar is engineered with defense-in-depth so that even the app's own interface can't reach beyond what it needs:

• The user interface runs in an OS sandbox, fully isolated from system internals, and talks to privileged operations only through a small, explicit, audited bridge.
• A strict Content Security Policy blocks remote or injected scripts; the app loads only its own local code.
• Navigation is locked down — the app can't be redirected to an external site, and outbound links are limited to opening https pages in your system browser.
• Clipboard, color, and measurement values are rendered as plain, escaped text — never as executable markup.

5. Open-source components

OpenBar is built on well-established open-source technology, including Electron and React, each used under its own license. These components run locally as part of the app and do not change how your data is handled: everything described on this page still applies.

6. You're in control

Your data is yours to manage at any time, directly inside the app:

• Turn clipboard history off entirely, or cap it to as few as 5 items.
• Clear all stored data with one button to reset settings and wipe clipboard & color history.
• Uninstall OpenBar like any other app on Windows or macOS whenever you wish; clear your data first if you want nothing left behind.
• Clear all stored data deliberately keeps your licence key, so the button cannot accidentally deactivate the product you paid for. Remove it separately with Deactivate in Options.

7. Buying OpenBar

Everything above describes the application, which collects nothing and transmits nothing. Buying it is a separate matter, and it does involve data — so here is exactly what happens.

• Payment is handled by Paddle. Paddle.com Market Limited is our merchant of record: it runs the checkout, takes the payment, and calculates the tax for your country. Your card details go to Paddle and never reach us — we never see or store them.
• We receive your email address, your order reference, and the name you type at checkout. That is all we get, and we use it to issue your serial and to help you if you write to us.
• Our licensing server keeps the record of your purchase — your serial, its status, and your email address — and, for each activation, the anonymous machine identifier described above with the time it last checked in. That is the entire server-side record. It exists so a refund can end a serial, and so we can free a seat when you replace a machine. It cannot tell us what you copy, capture, or sample, and it is kept for the life of the license. (Purchases from before serial numbers received a licence file with your name and email embedded in it; those keep working, read entirely locally.)
• Your serial email is sent through Resend, our email provider, which processes it in order to deliver it.
• No marketing. We do not add you to a mailing list, and we do not sell or share your details with anyone.

Once activated, the app contacts us for exactly one thing: the roughly-monthly licence check described above. Never for updates, never with your data — and a check that cannot get through never locks you out.

8. Changes to this page

If OpenBar's data practices ever change, we'll update this page and revise the "last updated" date above. Our commitment to keeping OpenBar local-first and private by default is core to the product.
