Terms of Service

These Terms govern your use of the Parallel browser extension (“the extension”), provided by Rabiul Hassan, operating as HSSN Labs (“we”, “us”). By installing or using the extension you agree to these Terms. If you don’t agree, please don’t use it.

1. License

The extension is licensed, not sold. Its license is the following text, which is also included as LICENSE.txt in the extension package:

Copyright © 2026 Rabiul Hassan (HSSN Labs). All rights reserved.

This software is provided for use under the terms of this license. You
may install and use it for your own personal purposes. You may not
copy, modify, redistribute, sell, sublicense, or remove or bypass any
licensing or payment checks in this software, in whole or in part,
without written permission from the copyright holder.

Use of the software is also subject to the Parallel Terms of Service.

This license terminates automatically if you breach any of these terms.

The software is provided "as is", without warranty of any kind.

These Terms, including the license above, are the whole agreement between you and us about the extension.

2. Acceptable use

You agree not to use the extension for anything unlawful, and not to tamper with, bypass, or interfere with its licensing or payment checks or with the services it relies on.

3. Free and Pro

The extension has a free tier with limits (for example, a cap on the number of folders you can create) and a paid Pro tier that unlocks unlimited sites, Bookmarks Toolbar pinning, and backup and restore. Features and limits may change over time.

Pro needs an occasional internet connection so the extension can confirm that your license is valid. If your license can’t be verified for an extended period, Pro features may pause until the extension can check again. Your saved shortcuts and bookmarks are not deleted when Pro pauses or ends.

4. Purchases and licenses

• Plans: Yearly (US$7.99 per year, renewing until cancelled) and Lifetime (US$19.99 one-time). The price shown at checkout applies and may include taxes.
• Payments are processed by Dodo Payments, our merchant of record, under its own terms. You can manage or cancel a subscription through Dodo’s customer portal. Cancelling stops future renewals, and Pro remains active until the end of the paid period.
• Each license key can be activated on up to 3 devices or browser profiles.
• “Lifetime” means for the lifetime of the Parallel product, not of the customer. If we ever discontinue the extension, we will give reasonable notice where practical.
• You are responsible for keeping your license key private. Keys must not be shared publicly or resold.

5. Refunds

You may request a refund within 7 days of purchase by emailing us at the address below from your purchase email.

If the extension does not work on your device, email us within those 7 days with your Firefox version, your operating system, and a description of what happens. We will try to fix the problem. If we can’t resolve it within 14 days of your report, you are entitled to a refund even if the 7 days have passed.

Refunds are issued through Dodo Payments. A refund ends your license, and Pro features stop working. Refunds are limited to one per customer, and we may decline a refund request that we reasonably believe is an abuse of this policy.

6. Your data

Your shortcuts and settings are stored on your device. How we handle data is described in our Privacy Policy. You are responsible for keeping your own backups, for example with the extension’s export feature.

7. Third-party services

The extension relies on Firefox features (bookmarks and containers) and on Dodo Payments. We are not responsible for changes, outages, or policies of those third parties, which may affect how the extension works.

8. Termination

You may stop using the extension at any time by uninstalling it. We may suspend or revoke a license, without refund, if you breach these Terms, including by bypassing licensing checks or abusing refunds. Your license also ends automatically if you breach these Terms.

9. Disclaimer of warranties

The extension is provided “as is” and “as available”, without warranty of any kind, express or implied. This includes any warranty of fitness for a particular purpose, non-infringement, or uninterrupted or error-free operation. We do not guarantee that the extension will work with every browser version, device, or website.

10. Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, or consequential damages, or for loss of data, bookmarks, shortcuts, or profits, arising from your use of the extension. We are also not liable for losses caused by Firefox, Dodo Payments, or other third parties. Our total liability for any claim is limited to the amount you paid for the extension in the 12 months before the claim. Nothing in these Terms excludes liability that cannot be excluded under applicable law.

11. Changes

We may update these Terms. We will change the date above, and continued use after an update means you accept it. If you disagree with a change, stop using the extension.

12. Governing law

These Terms are governed by the laws of India. Disputes will be heard in the courts at Guwahati, Assam, India, except where your local consumer law gives you other rights.
