Terms of Use

Last updated: April 23, 2026

These terms apply to your use of gpdedup, a macOS application published by Franz Enzenhofer (Fullstack Optimization), Vienna, Austria. By installing or using gpdedup you agree to these terms. If you do not agree, do not install or use the app.

1. License

Subject to these terms and your compliance with the Mac App Store end user license agreement, you are granted a personal, non-exclusive, non-transferable license to install and use gpdedup on Apple-branded computers that you own or control.

2. Not affiliated with Google

gpdedup is NOT affiliated with, endorsed by, or sponsored by Google LLC. Google Photos is a trademark of Google LLC. gpdedup is an independent third-party Mac app that acts on your behalf using your own logged-in Google Photos session.

3. Your Google account is yours

You are responsible for using your Google account in compliance with Google's own terms of service. gpdedup does not hold, read, or transmit your Google password. It holds an authenticated session cookie locally on your Mac, in the macOS Keychain, so that you do not have to sign in again every launch.

4. AS IS, no warranty

gpdedup is delivered AS IS, without any warranty of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. gpdedup uses publicly reachable HTTPS endpoints that Google Photos on the web uses. Google may change, restrict, or discontinue those endpoints at any time, without notice. If that happens, gpdedup may stop working, in part or in full, and the developer is under no obligation to ship a fix.

5. Back up first

Before running any deduplication tool, including gpdedup, you should export a full backup of your Google Photos library using Google Takeout. The app's onboarding asks you to confirm that you have done this. The developer accepts no liability for data loss that a contemporaneous backup would have prevented.

6. Destructive actions are yours

Every "move to Trash" action in gpdedup requires your explicit confirmation and an exact item count is displayed before execution. gpdedup does not permanently delete. Items moved to Google Photos Trash are retained by Google for 60 days, during which you can restore them from photos.google.com. gpdedup does not, and will not, implement a "permanently delete" or "empty trash" operation.

7. No developer-operated server

gpdedup does not operate or transmit your data through any backend service we run. All network traffic is between your Mac and Google. Google's handling of that traffic is governed by Google's own terms and privacy policy.

8. Limitation of liability

To the maximum extent permitted by applicable law, in no event shall the developer be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or goodwill, arising from your use of gpdedup. The developer's total liability, if any, shall not exceed the amount you paid for the app.

9. Updates

Updates are distributed via the Mac App Store. Updates may add, change, or remove features. The developer is under no obligation to provide updates.

10. Termination

You may stop using gpdedup at any time by uninstalling it. The developer may stop providing updates or take the app off sale at any time. Clauses that by their nature survive termination (for example, limitations of liability, governing law) survive termination.

11. Governing law

These terms are governed by the laws of the Republic of Austria, without regard to its conflict-of-laws rules. For consumers, mandatory consumer-protection law of your country of residence applies. Exclusive venue, to the extent permitted, is Vienna, Austria.

12. Changes to these terms

If we change these terms materially, the "Last updated" date changes and the new terms are surfaced in the app's release notes.
