Terms of Service

Last updated: February 21, 2026

1. Agreement to Terms

By accessing or using Markbridge ("the Service"), operated by Markbridge ("we," "us," or "our"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not access or use the Service. These Terms constitute a legally binding agreement between you and Markbridge.

2. Description of Service

Markbridge is a software-as-a-service platform that automatically syncs your X (formerly Twitter) bookmarks to your Notion workspace. The Service accesses your X bookmarks through the X API via OAuth authentication, and creates corresponding pages in a Notion database of your choosing via the Notion API. The Service may also expand and archive full threads associated with bookmarked posts.

3. Account Registration and Eligibility

To use the Service, you must create an account by authenticating through X (Twitter) or Google OAuth. You must be at least 18 years of age, or the age of legal majority in your jurisdiction, to create an account and use the Service. By registering, you represent and warrant that all information you provide is accurate and current. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. You must notify us immediately at support@markbridge.app if you become aware of any unauthorized use of your account.

4. Free Trial Terms

New users receive 10 free bookmark exports at no charge. No credit card is required. Once you have used all 10 free bookmarks, syncing will stop until you subscribe to a paid plan. You will not be charged automatically; subscribing requires an explicit action on your part through the dashboard.

5. Subscription Terms and Billing

After your free trial, the Service is available under the following subscription plans:

  • Monthly Plan: $9.00 per month, billed monthly
  • Annual Plan: $90.00 per year, billed annually

Each plan includes 500 bookmark syncs per billing period. If you exceed 500 bookmarks in a billing period, an overage fee of $0.01 per additional bookmark will apply. Overage charges are billed at the end of each billing period.

All fees are non-refundable except as expressly set forth in these Terms or as required by applicable law. We reserve the right to change our pricing with 30 days' advance notice. Continued use of the Service after a price change constitutes acceptance of the new pricing.

Payment is processed securely through Stripe. By providing your payment information, you authorize us to charge your payment method for all fees incurred under your account.

6. Cancellation Policy

You may cancel your subscription at any time through your account settings in the dashboard. Upon cancellation, your subscription will remain active until the end of your current billing period. After that, bookmark syncing will stop. Your existing synced data in Notion will not be affected by cancellation; pages already created in your Notion workspace will remain. You may resubscribe at any time to resume the Service.

7. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose or in violation of any applicable laws or regulations
  • Attempt to reverse engineer, decompile, or disassemble any part of the Service
  • Interfere with or disrupt the integrity or performance of the Service or its underlying infrastructure
  • Access the Service through automated means (bots, scrapers, or similar tools) other than the Service's own automation features
  • Use the Service to transmit malware, viruses, or any destructive code
  • Resell, sublicense, or otherwise commercially exploit the Service without our express written consent
  • Create multiple accounts to circumvent usage limits or billing
  • Violate the terms of service of X (Twitter) or Notion through your use of the Service

We reserve the right to suspend or terminate your account if we determine, in our sole discretion, that you have violated these acceptable use provisions.

8. Data Usage and Third-Party Access

To provide the Service, we access the following data on your behalf:

  • X (Twitter) Data: We access your X bookmarks via the X API using OAuth 2.0 authentication. We read your bookmarked posts, including their content, author information, media, and associated thread data.
  • Notion Data: We create pages in your designated Notion database using the Notion API. We access your Notion workspace identifier and the specific database you select for bookmark syncing.

We do not post to your X account, modify your X bookmarks, or alter any data in your Notion workspace beyond creating new pages in your designated database. For further details on how we handle your data, please review our Privacy Policy.

9. Intellectual Property

You retain full ownership of all data you provide to the Service and all content synced through the Service. Your X bookmarks and the pages created in your Notion workspace belong to you. Markbridge does not claim any ownership rights over your content.

The Service itself, including its software, design, branding, logos, and documentation, is the intellectual property of Markbridge and is protected by applicable intellectual property laws. You are granted a limited, non-exclusive, non-transferable license to use the Service for its intended purpose during the term of your subscription.

10. Disclaimer of Warranties

The Service is provided on an "as is" and "as available" basis without warranties of any kind, whether express, implied, or statutory. We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components. We do not guarantee the accuracy, completeness, or timeliness of bookmark syncing. Syncing depends on the availability and proper functioning of the X API and Notion API, which are third-party services outside our control. To the fullest extent permitted by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

11. Limitation of Liability

To the maximum extent permitted by applicable law, Markbridge and its officers, directors, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill, arising out of or in connection with your use of the Service, regardless of the theory of liability. Our total aggregate liability for any claims arising under these Terms shall not exceed the amount you paid to us in the 12 months preceding the claim. This limitation applies even if we have been advised of the possibility of such damages.

12. Indemnification

You agree to indemnify, defend, and hold harmless Markbridge and its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to your use of the Service, your violation of these Terms, or your violation of any rights of a third party.

13. Termination

We may suspend or terminate your access to the Service at any time, with or without cause, and with or without notice. Upon termination, your right to use the Service ceases immediately. We may delete your account data in accordance with our Privacy Policy. Sections of these Terms that by their nature should survive termination shall survive, including but not limited to intellectual property provisions, disclaimers, limitations of liability, and indemnification.

14. Governing Law and Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions. Any dispute arising from or relating to these Terms or the Service shall be resolved through binding arbitration in accordance with the rules of the American Arbitration Association. The arbitration shall take place in the State of Delaware. You agree that any dispute resolution proceedings will be conducted on an individual basis and not as a class action.

15. Changes to These Terms

We reserve the right to modify these Terms at any time. If we make material changes, we will notify you by email or by posting a prominent notice on the Service at least 30 days before the changes take effect. Your continued use of the Service after the effective date of any changes constitutes your acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the Service and cancel your subscription.

16. Severability

If any provision of these Terms is held to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect. The invalid or unenforceable provision shall be modified to the minimum extent necessary to make it valid and enforceable.

17. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Markbridge regarding your use of the Service and supersede all prior and contemporaneous agreements, proposals, or representations, written or oral, concerning the subject matter of these Terms.
