1. Who these terms are with

These terms are between you and Maksim Pashkov, Street Example 1, 123456 Examplecity, Serbia (“the developer”). By installing or using JstSync on your phone or computer you agree to them. If you get the Android app from Google Play, Google Play’s own terms apply to the download as well.

2. Your licence to use JstSync

JstSync is proprietary software. All rights reserved. The developer gives you a free, personal, non-exclusive licence to install and use the apps on devices you own or control.

  • You may not sell, rent or redistribute the apps, or publish changed copies of them.
  • You may not remove the copyright and licence notices, including the third-party notices that come with the apps.
  • Nothing here limits rights that the law or an open-source licence gives you anyway.

3. Your files

Your files stay yours. JstSync copies the folders you choose from your phone to your own computer and sends none of them to the developer. You are responsible for having the right to copy the files you choose, and for keeping your own backups: JstSync is a copy tool, not a backup service, and copying goes one way only.

4. Removing synced files

If you turn on “Remove synced files”, the phone app deletes older files from your phone after they are on your computer. It is off by default. You choose to turn it on, and you should check that your computer keeps those files safe before you do.

5. Open-source parts

The apps include open-source software under its own licences, such as MIT, Apache 2.0 and the Slint Royalty-free licence. Those licences apply to those parts. They are listed on the open-source licences page and in the apps.

6. No warranty

JstSync is free and provided “as is”, without any warranty that it will be error-free, always available, or fit for a particular purpose, to the extent the law allows.

7. Limits of liability

To the extent the law allows, the developer is not liable for lost files or data, or for indirect damage, that comes from using JstSync. Liability for intent, gross negligence, and injury to life, body or health stays as the law sets it.

8. Age

JstSync is meant for people aged 13 and older.

9. Changes and ending

If these terms change, the new text is published on this page with a new date. You can stop using JstSync at any time by uninstalling it. The developer may stop offering the apps; the copies you have keep working, but they may no longer get updates.

10. Law and contact

These terms are governed by the law of Serbia, without taking away the protection that the consumer law of the country where you live gives you. Questions: mpashkov.work@gmail.com.
