Terms & Conditions

Effective March 15, 2026  ·  Please read before using SynciZen

1. Acceptance of Terms

By downloading, installing, or using SynciZen (the "Software"), you agree to be bound by these Terms & Conditions ("Terms"). If you do not agree to these Terms, do not install or use the Software.

These Terms constitute a legally binding agreement between you and SynciZen ("we", "us", or "our"). Use of the Software is also subject to our Privacy Policy and Refund Policy, which are incorporated herein by reference.

2. Merchant of Record — Polar

SynciZen is sold through Polar, our authorised reseller and Merchant of Record. When you purchase SynciZen, your purchase contract for payment purposes is with Polar. By completing a purchase you also agree to Polar's Consumer Terms.

Polar handles all payment processing, invoicing, and tax compliance on our behalf. Any billing disputes or payment queries should be directed to Polar's support.

3. License Grant

Subject to your compliance with these Terms and payment of the applicable license fee, we grant you a personal, non-exclusive, non-transferable, limited license to install and use the Software on devices you own or control, solely for your personal or internal business purposes.

This license covers:

  • Use across unlimited cloud accounts on all supported providers (Google Drive, OneDrive, Dropbox, Proton Drive, Box, pCloud, Mega, Yandex Disk, Amazon S3, Cloudflare R2, Wasabi, Backblaze B2, Azure Blob Storage, SFTP, WebDAV, and others supported via rclone)
  • Installation on the number of devices specified in your purchased license tier
  • All feature updates released during the applicable license period, where stated at the time of purchase

4. Restrictions

You must not:

  • Copy, modify, adapt, translate, or create derivative works of the Software
  • Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Software
  • Sublicense, sell, resell, transfer, assign, share, or otherwise commercially exploit the Software or your license key
  • Circumvent or attempt to circumvent any licensing or activation mechanism
  • Remove or alter any proprietary notices, labels, or marks on the Software
  • Use the Software in any way that violates applicable law or regulation
  • Use the Software to store, transmit, or sync unlawful, infringing, or harmful content

5. Ownership

The Software and all related intellectual property rights remain the exclusive property of SynciZen and its licensors. These Terms do not transfer any ownership rights to you. All rights not expressly granted are reserved.

6. Payment & Refunds

Pricing is displayed at the point of purchase. All transactions are processed by Polar in the applicable currency. You are responsible for any applicable taxes not collected by Polar at checkout.

Refunds are governed by our Refund Policy. We offer a 30-day money-back guarantee on all purchases. EU and UK consumers retain their statutory cooling-off rights as described in the Refund Policy.

7. Free Trial

We offer a 15-day free trial of the full Software with no payment required. At the end of the trial period the Software may restrict functionality until a license is purchased. We reserve the right to modify or discontinue the free trial at any time without notice.

8. Third-Party Services

The Software connects to third-party cloud storage providers (Google Drive, OneDrive, Dropbox, Proton Drive, Amazon S3, and others). Your use of those services is governed by the respective provider's terms of service and privacy policies. We are not responsible for the availability, accuracy, security, or performance of any third-party service.

SynciZen uses rclone as its underlying sync engine. rclone is an open-source component bundled with the Software and is subject to its own license. We are not responsible for issues arising from rclone or any other bundled open-source component.

9. Data and Privacy

SynciZen is a locally-first application. All configuration, sync metadata, and logs are stored exclusively on your device. We do not collect telemetry, analytics, or file contents. Please review our Privacy Policy for full details.

The Software accesses your cloud accounts solely to perform the sync operations you configure. We do not store your cloud files or credentials on our servers.

10. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the Software will be error-free, uninterrupted, or free of harmful components. File synchronisation inherently carries risk — you are solely responsible for maintaining independent backups of your data at all times.

Nothing in these Terms excludes or limits warranties that cannot be excluded or limited under applicable consumer protection law.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SYNCIZEN BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, LOSS OF PROFITS, LOSS OF BUSINESS, OR BUSINESS INTERRUPTION, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY TO YOU SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

Nothing in these Terms limits liability that cannot be limited under applicable law (including liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation).

12. Indemnification

You agree to indemnify and hold harmless SynciZen and its officers, employees, and agents from and against any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your use of the Software in violation of these Terms or applicable law.

13. Updates and Changes to the Software

We may release updates, patches, or new versions of the Software from time to time. Your license covers updates released during the applicable license period, where stated at the time of purchase. We reserve the right to modify, suspend, or discontinue any feature of the Software with reasonable prior notice where practicable.

14. Termination

These Terms are effective until terminated. Your rights under these Terms will terminate automatically and without notice if you breach any provision. Upon termination you must cease all use of the Software and destroy all copies in your possession. Sections 5, 10, 11, 12, and 16 survive termination.

15. Changes to These Terms

We may update these Terms from time to time. The "Effective" date at the top of this page will reflect any changes. Continued use of the Software after changes are posted constitutes your acceptance of the revised Terms. For material changes we will make reasonable efforts to notify you via the SynciZen website or within the application.

16. Governing Law

These Terms are governed by and construed in accordance with applicable law. Where you are a consumer located in the EU or UK, you also benefit from any mandatory provisions of the consumer protection laws of your country of residence, which these Terms do not override.
