Privacy Policy

SimParcel ("the App") is a free, open-source macOS application developed by Vadim Katenin ("I", "me"). This Privacy Policy explains what the App does and does not do with your information. The App's source code is public at github.com/VadimKat/SimParcel, so everything described here can be checked.

1. The short version

There are no user accounts, no analytics, no crash reporting, no advertising, and no tracking. I do not receive any information about you or about how you use the App. The files you send stay on your Mac. The only network request the App makes on its own is a daily check for updates, described in section 4.

2. The files you send

The App works only with items you give it: files and folders you drop onto its window or choose in the standard macOS open panel, and links you drop or type. It does not browse your disk, index your files, or read your clipboard.

To send an item, the App passes it to Apple's own xcrun simctl tool, or copies it into the Files storage of a simulator. Both the source and the destination are on your Mac: simulators store their data in your user folder, and nothing is uploaded anywhere. Thumbnails in the queue are generated locally by macOS. The queue itself is not saved and is gone when you quit the App.

The App is not sandboxed, because it has to run Xcode's command line tools. It still reads only the items you hand it. macOS may ask you to allow access when you drop a file from a protected folder such as Documents or Downloads.

3. What the App stores on your Mac

The App remembers which simulator you selected last, and the update framework remembers when it last checked for updates. Both are kept in the App's preferences on your Mac and are never sent anywhere.

4. Update checks

The App uses the open-source Sparkle framework to stay up to date. Once a day, and whenever you choose Check for Updates…, it downloads a small file describing the latest version from GitHub, where the App is published. If you agree to install an update, the new version is downloaded from GitHub too.

These requests contain no information about you, your files or your Mac beyond what any download involves: GitHub sees your IP address and a user agent naming the App and its version. The App's optional system-profile reporting in Sparkle is turned off. GitHub's handling of that request is governed by the GitHub Privacy Statement. Automatic checks are on by default. To turn them off, quit the App and run defaults write com.vadimkatenin.SimParcel SUEnableAutomaticChecks -bool false in Terminal; Check for Updates… keeps working on demand.

5. Downloading and installing

If you download the App from GitHub or install it with Homebrew, those services handle the download under their own privacy policies. Homebrew in particular collects its own anonymous usage analytics unless you have turned them off; that is independent of the App.

6. Support email

If you write to [email protected] or open a GitHub issue, I receive what you send, including your email address or GitHub username. I use it only to answer you and to fix the problem you report, and I do not share it. Issues on GitHub are public, so do not include anything you would not want others to see.

7. Children's privacy

The App is a developer tool, is not directed at children under the age of 13, and does not collect personal information from anyone.

8. Your rights

Privacy laws such as the GDPR and the CCPA give you rights of access, correction, deletion, portability, and objection over personal data held about you. The App holds no personal data about you on my side. If you have written to me, write again to [email protected] and I will find, correct or delete your messages. I do not sell or share personal information, and never have. If you are in the EU or UK, you may also complain to your local data protection authority.

9. Changes to this policy

If this policy changes, the "Last updated" date at the top of this page changes with it. Material changes will be reflected in the App's release notes.
