How to buy
- Select any Upgrade or Get Prettify Pro button. You can find one on the landing page pricing, in Settings under License, or on any Pro paywall.
- Checkout opens in a new tab on Lemon Squeezy. Lemon Squeezy is the Merchant of Record and handles payment and tax.
- After purchase, Lemon Squeezy emails you a license key.
Checkout needs an internet connection.
Activate a license key
Activation works the same on the web and on the desktop app.
- Open Settings.
- In the License section, paste your license key.
- Select Activate.
You can also select "Already have a license key?" on any upgrade prompt. It takes you to Settings. Activation needs an internet connection.
Use Pro on several devices
A license key activates on up to 5 devices. Each device uses one slot.
If you reach the limit, activation fails with a device-limit message. Deactivate Prettify on another device first, then try again.
Deactivate or move to another device
To free this device's slot, open Settings, go to License, and select Deactivate. This releases the slot and removes the key from this device.
If the slot cannot be released, free it from your Lemon Squeezy dashboard.
Offline behavior
Your license is stored on your device, so Pro features keep working offline after you activate.
Prettify re-checks your license about once a week. A failed check does not revoke Pro. A refund, or a deactivation on another device, reverts you to Free on the next successful check.
Activation, deactivation, checkout, and Pro short share links need a connection.
Refunds
Pro has a 30-day money-back guarantee, no questions asked. To request a refund, use the in-app bug report, or email offleashlabs@gmail.com.
Desktop
Pro works the same on the native macOS desktop app. Windows and Linux builds are also available on /download. The price and the Pro features are the same. See Desktop app.
