Terms of Service

Last updated: January 29, 2025

1. Acceptance of Terms

By installing the Capsule browser extension, creating an account, or using any Capsule services ("Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the Service.

Capsule is operated by Capsule ("we," "our," or "us"). These Terms constitute a legally binding agreement between you and Capsule.

2. Description of Service

Capsule is a browser extension that tracks your browsing sessions and organizes visited pages into interactive knowledge graphs using AI-powered clustering. The Service includes:

  • Automatic browsing session tracking
  • Semantic analysis and clustering of visited pages
  • Interactive 2D and list visualizations
  • Session search and retrieval
  • The Bridge — contextual resurfacing of past research
  • Optional cloud sync and account management
  • Notes and annotations on pages

3. Account Registration

You may use Capsule locally without an account. To access cloud sync, billing, and certain features, you must create an account by providing a valid email address and password.

You agree to:

  • Provide accurate and complete registration information
  • Maintain the security of your account credentials
  • Notify us immediately of any unauthorized access to your account
  • Accept responsibility for all activity that occurs under your account

You must be at least 13 years old to use the Service. If you are under 18, you must have parental or guardian consent.

4. Plans and Pricing

4.1 Free Plan

The free plan includes limited access to the Service with the following constraints:

  • Up to 50 nodes per session
  • Up to 3 saved sessions
  • Basic clustering and visualization

4.2 Pro Plan

The Pro plan provides unlimited access to all features. Pro plan pricing is displayed on our website and within the extension at the time of purchase.

4.3 Billing

Pro subscriptions are billed through Stripe on a recurring basis. By subscribing, you authorize us to charge your payment method at the beginning of each billing cycle. All fees are stated in USD unless otherwise specified.

4.4 Cancellation and Refunds

You may cancel your Pro subscription at any time through your account dashboard. Upon cancellation, you retain access to Pro features until the end of your current billing period. We do not provide prorated refunds for partial billing periods. If you believe you were charged in error, contact us within 30 days.

Because the Pro Plan provides immediate access to digital features, all fees are non-refundable except as required by local consumer protection laws. Abuse of the refund or chargeback process may result in permanent account termination.

5. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose
  • Attempt to reverse engineer, decompile, or disassemble the Service
  • Interfere with or disrupt the Service or its servers
  • Circumvent usage limits or access restrictions
  • Use automated means to access the Service beyond normal extension operation
  • Resell, redistribute, or sublicense access to the Service
  • Use the Service to collect data on other people's browsing activity

We reserve the right to suspend or terminate accounts that violate these terms.

6. Your Data

You retain ownership of all data you generate through the Service, including your browsing sessions, notes, and annotations. By using cloud sync, you grant us a limited license to store and process your data solely to provide the Service.

You are responsible for the content you access through your browser. We do not monitor, review, or endorse any content you visit or store in your sessions.

For details on how we handle your data, see our Privacy Policy.

Our use and transfer of information received from Google APIs to any other app will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. We do not sell, rent, or monetize your personal data to third parties for advertising or marketing.

7. AI-Generated Content

The Service uses artificial intelligence (Google Gemini) to generate cluster labels, session summaries, and content groupings. This AI-generated content is provided for informational and organizational purposes only.

The Service integrates third-party AI models (including Google Gemini). You acknowledge that AI-generated content may include "hallucinations" or inaccuracies. Capsule is not responsible for any actions taken based on these automated summaries. We do not permit these third parties to use your private data to train their models without your explicit consent.

Disclaimer: AI-generated labels and summaries may be inaccurate, incomplete, or misleading. We do not guarantee the accuracy of AI-generated content. You should not rely on it for critical decisions.

8. Intellectual Property

The Service, including its code, design, algorithms, and documentation, is owned by Capsule and protected by intellectual property laws. These Terms do not grant you any rights to our trademarks, branding, or proprietary technology.

You may not copy, modify, or create derivative works based on the Service except as expressly permitted by these Terms or applicable law.

9. Service Availability

We strive to maintain Service availability but do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control.

Core extension functionality (local session tracking, graph visualization) operates independently of our servers. Cloud features (clustering, sync, Bridge) require an active internet connection and server availability.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, STACKS AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE.

OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU HAVE PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR $100 USD, WHICHEVER IS GREATER.

11. Disclaimer of Warranties

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

We do not warrant that the Service will be error-free, secure, or available at all times, or that AI-generated content will be accurate or complete.

12. Indemnification

You agree to indemnify and hold harmless Capsule and its officers, directors, employees, and agents from any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to your use of the Service or violation of these Terms.

13. Termination

You may stop using the Service at any time by uninstalling the extension and, if applicable, deleting your account.

We may suspend or terminate your access to the Service at any time for violation of these Terms or for any other reason with reasonable notice, except in cases of serious violations where immediate termination may be necessary.

Upon termination, your right to use the Service ceases immediately. Locally stored data remains on your device. Cloud-synced data will be deleted in accordance with our Privacy Policy.

14. Changes to These Terms

We may modify these Terms at any time. We will provide notice of material changes by updating the "Last updated" date and, where possible, through the extension or email. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

If you do not agree with the revised Terms, you must stop using the Service and delete your account.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles. Any disputes arising from these Terms or the Service shall be resolved in the courts of the United States.

16. Severability

If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full effect.
