Terms

QuietJump is sold through Lemon Squeezy, acting as merchant of record. That means the sale itself is theirs: payment, VAT, invoicing and the handling of refunds are covered by their terms, which you accept at their checkout. What is below covers your use of the software.

Last updated 9 September 2026.

1. What you may do

On paying for a licence you may:

• Install and use QuietJump on any Mac you own or control, as many as you personally use.
• Keep using this version indefinitely. The purchase is one payment, not a subscription, and it does not expire or phone home to stay working.

The licence is yours as an individual. If you want it deployed across an organisation, ask at support@alexvestea.com and the answer is not automatically no.

2. What you may not do

• Redistribute it. Not the application, not the disk image, not your download link, publicly or privately, for a fee or for nothing.
• Resell, rent, or sublicense it, or include it in anything you distribute.
• Remove or alter the copyright notice or this agreement.
• Reverse engineer, decompile, or disassemble it, except where applicable law grants you that right regardless of what this agreement says. Several jurisdictions do, particularly for interoperability, and this clause does not attempt to take that away.

3. What the app does with the access it asks for

Stated here because the app asks for Accessibility permission, which is a powerful grant and you are entitled to know what it is spent on.

• Accessibility permission is used to read the list of open windows and their titles, and to raise, minimise and hide windows when you ask it to. Nothing else.
• The app makes no network connections. It has no update checker, no telemetry, no analytics, no crash reporting and no licence check. It does not collect, transmit or store any information about you or about what you do. You can confirm this rather than take it on trust: nettop -p QuietJump.
• Nothing is kept beyond the handful of on and off settings you set yourself, which live in the app's own preferences on your Mac.

4. Ownership

QuietJump is licensed, not sold. The copyright holder retains all rights in it. You own the licence to use it; you do not own the software.

The app declares symbols that macOS exports but its SDK does not, and states the layout of a record the WindowServer reads. Those declarations, their names and their offsets are facts about Apple's own interfaces rather than anything written here, and are not claimed as the copyright holder's. They are named and explained in the writeup.

5. Refunds

If it is not for you, email support@alexvestea.com and ask for a refund within 30 days. You will get one, without being asked to justify it.

Any statutory right of withdrawal you have as a consumer stands on top of that, not instead of it.

6. Updates

Any updates supplied are covered by these same terms unless they arrive with terms of their own. Nothing here promises that updates will be made.

7. If you breach it

The licence ends immediately, and you should stop using the software and delete it. It is restored if you cure the breach within 30 days of being told of it, unless it has already been terminated in writing.

8. No warranty

The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and noninfringement. In no event shall the authors or copyright holders be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise, arising from, out of or in connection with the software or the use or other dealings in the software.

Nothing here limits any liability that cannot lawfully be limited, or affects consumer rights you have under the law of the country you live in, which stand regardless of what is written here.

9. Governing law

These terms are governed by the law of Romania, without regard to its conflict of law rules.

If you bought a licence as a consumer, that choice does not deprive you of the protection of any mandatory provision of the law of the country you live in, and it does not affect where you are entitled to bring proceedings.
