Questions, answered

OneNotch needs an Apple silicon Mac running macOS 15 or later. It has layouts for MacBooks with a notch, MacBooks and displays without one, and external displays. It is Mac-only: there is no Windows, Linux, iPhone or iPad version.

Yes. On a screen without a notch, including an external display, OneNotch becomes a pill that floats at the top of the screen and carries the same pages as on a MacBook.

No. There is nothing to sign up for. Download it, open it, and use it.

The app comes in 18 languages: English, Arabic, Czech, German, Spanish, French, Hungarian, Italian, Japanese, Korean, Polish, Brazilian Portuguese, Russian, Turkish, Ukrainian, Vietnamese, Simplified Chinese and Traditional Chinese. It follows your Mac's language by default, and you can pick another one in Settings > General.

Only if you want it to. In Settings > General, Hide on screen capture lets you choose when OneNotch stays out of screenshots and recordings, including the ones OneNotch takes itself.

OneNotch checks for new versions on its own and offers to install them. You can also check by hand from Settings. The release notes on the Updates page list every change.

No. Free is not a trial and never expires. Music, lyrics, Live Activities, screenshots and markup, Quick Translate, file actions, window snapping, AI agent monitoring and today's calendar are all in Free. Pro is optional and raises limits or adds advanced tools.

The clipboard keeps your 50 most recent items for up to 24 hours, and you get one board with up to 10 pins. Pro-only tools include iCloud sync, scrolling capture, background removal, auto-redaction, the full dictionary with pronunciation, replacing selected text with its translation, extra window layouts, and calendar summaries and new events for days other than today.

Pro keeps up to 1,000 clipboard items for as long as you choose, gives you 20 boards with 200 pins each, and adds iCloud sync between your Macs. It also unlocks the advanced capture and markup tools, the full dictionary, more window layouts, and calendar summaries and new events for any day. One Pro license works on up to two Macs.

No. Pro and Supporter are one-time purchases. You pay once and the license is yours, with all future updates included.

Supporter has exactly the same features as Pro. It costs more, works on up to five Macs, and adds a supporter badge in the app. It is for people who want to help OneNotch stay independent.

You can ask for a refund within 7 days of purchase. Email support@tryonenotch.com from the address you used at checkout. A refunded license stops unlocking Pro the next time the app checks it.

Open OneNotch's Settings, go to the About tab, and paste your license key. The key is in the email you received at checkout. OneNotch stores it in your Mac's Keychain.

On the old Mac, open Settings > About and choose Deactivate License. That frees its seat, and you can then activate the same key on the new Mac. A Pro key has two seats and a Supporter key has five.

Your key was emailed to the address you used at checkout, so search that inbox for your order receipt. You can also sign in with the same email at onenotch.lemonsqueezy.com/billing to see your orders and license keys.

Not for everyday use. OneNotch re-checks your license with Lemon Squeezy every few days during the first two months and about once a month after that. If it cannot connect, Pro stays unlocked for up to 60 days after the last successful check.

Clipboard history, boards and screenshots are stored on your Mac. OneNotch does not run a server that holds your clipboard. If you turn on iCloud sync, the history goes to your own private iCloud, stored in encrypted fields.

No. iCloud sync (a Pro feature) syncs clipboard history between your Macs only, and OneNotch has no iPhone or iPad app. Images larger than 10 MB stay on the Mac they were copied on.

Yes. OneNotch skips anything a password manager marks as concealed or temporary, you can add apps to an ignore list, and you can pause clipboard capture entirely in Settings.

Translation, synced lyrics, link previews, currency rates, update checks and license checks all connect to the internet when you use them. Clipboard content is never uploaded by OneNotch itself. The next question covers translation, which is the one that sends your text.

By default OneNotch translates on your Mac with Apple's on-device translation when macOS has that language pair, and otherwise falls back to Google Translate. If you want nothing to leave your Mac, choose Apple (on-device) in the translation settings. If you add your own Claude, OpenAI or Gemini key, your text goes to that provider instead.

Anonymous usage data and crash reports, and nothing else. Usage data is at most one small signal per day with your app and macOS version, Mac model, language, which settings are on, and feature counts. A crash report holds the crash details and the Mac model. Neither contains your clipboard, files, window titles, name or email. Turn it all off with Send anonymous usage data in Settings > General.

Each permission switches on one feature, and you can skip any of them. Accessibility lets OneNotch paste into other apps, snap windows and replace the volume HUD. Screen Recording is for screenshots. Calendar and Reminders show and create your events. Full Disk Access is optional and only improves Focus mode details. You can change all of them later in macOS System Settings.

Claude Code and Codex running in the terminal. OneNotch shows each session, what it is doing, usage and limits, and lets you approve or deny permission requests from the notch. It does not track the Claude or Codex desktop apps, because they do not write the files OneNotch reads.

It is off by default. When you turn it on, OneNotch adds small hooks to Claude Code and Codex so they can report their status, and it reads their session files on your Mac. You can remove the hooks at any time with the Remove button in the AI settings.
