Help and support

Short answers to common questions. Anything else: write to hello@sunbend.app. We usually reply within two working days.

Install Sunbend

Sunbend needs macOS 26 or later on a Mac with Apple silicon. Because it is sold directly and not notarized by Apple, you approve it once: open Sunbend, choose Done when macOS warns you, then go to System Settings → Privacy & Security and choose Open Anyway. Step-by-step instructions are on the download page.

Start the trial or activate a license

In Sunbend, open Settings → License. Choose Start 7-day trial; no card or account is needed. After buying, paste the code from your email and choose Activate. Both need an internet connection.

Move your license to another Mac

A license works on one computer at a time. On the old Mac, open Settings → License and choose Deactivate this computer, then activate the code on the new Mac. If the old Mac is lost or broken, open pay.sunbend.app/manage, enter your purchase email, open the secure link and choose Move to another computer. You receive a new code by email, and the old computer stops using the license at its next online check.

Lost your license code

Open pay.sunbend.app/manage and enter the email you used to buy. We send a secure link, valid for 15 minutes, that shows your license and lets you choose Recover license code. Recovering a code does not deactivate your computer.

No access to your purchase email

Write to hello@sunbend.app from your new address. Include the receipt number from your Stripe receipt, or the purchase date and the last four digits of the card you used. After we confirm the purchase, we move your license to the new address and you can manage it from there.

Using Sunbend offline

Sunbend checks your license online at least every seven days, with one extra day of grace. If it cannot connect for longer, color changes pause until it can verify again. Restore normal colors and Quit always keep working, and your settings are never lost. If the license service is briefly unavailable, Sunbend keeps working and retries automatically.

Cancel a monthly subscription

Open pay.sunbend.app/manage, enter your purchase email, open the secure link and choose Manage billing or cancel. Cancel there at any time; Sunbend keeps working until the end of the period you have paid for, and you are not charged again. You can also choose Upgrade to lifetime on the same page.

Refunds

Every purchase has a 14-day money-back guarantee: lifetime, and the first payment of a monthly subscription. Reply to your license email or write to hello@sunbend.app from your purchase email within 14 days. We refund the full amount to your original payment method; banks usually show it within 5–10 working days. The license is deactivated. Details are in the terms.

What lifetime includes

Lifetime is a one-time purchase for one active computer. It includes all future Sunbend versions, and Windows and Linux versions if and when they are released. If Sunbend is ever discontinued, lifetime owners receive a final version that works without the online license check.

Remove Sunbend

Choose Quit Sunbend from its menu; your normal colors are restored. If you have a paid license, deactivate it first in Settings → License so you can use it elsewhere. Then move Sunbend from Applications to the Trash. Settings and the license file are in ~/Library/Application Support, in the Sunbend and app.sunbend.mac folders.
