Terms of Service

Last Updated: April 10, 2026

1. Acceptance of Terms

By accessing and using Vistacker, you accept and agree to be bound by the terms and provisions of this agreement. These Terms of Service constitute a binding agreement between you and Cyrush LLC. If you do not agree to abide by the above, please do not use this service.

2. Changes to Terms

Cyrush LLC reserves the right to change these terms and conditions at any time. Your continued use of Vistacker following the posting of changes to these terms will mean you accept those changes.

3. Description of Service

Vistacker is a CLI-first task management tool that lets you organize tasks in stacks and vaults, sync across devices, and optionally encrypt your data client-side. The service is provided via a hosted API, a command-line interface, and a companion iOS app.

4. Account Registration

You may sign in using a supported OAuth provider (GitHub or Google). You are responsible for maintaining the confidentiality of your access tokens and for all activity that occurs under your account. You agree to notify us immediately of any unauthorized use of your account.

5. Acceptable Use

You agree not to use Vistacker to:

  • Upload, store, or transmit any content that is unlawful, harmful, threatening, abusive, defamatory, or otherwise objectionable;
  • Impersonate any person or entity or misrepresent your affiliation with any person or entity;
  • Interfere with or disrupt the service or servers or networks connected to the service;
  • Attempt to gain unauthorized access to any part of the service or any other account;
  • Use the service to transmit any unsolicited commercial communications or spam;
  • Reverse engineer, decompile, or disassemble any component of the service;
  • Use automated means to access the service in a manner that exceeds reasonable personal use.

6. Data and Privacy

Your privacy is important to us. Vistacker syncs your tasks and notes over TLS-encrypted connections. You may optionally enable client-side AES-256 encryption so your data is encrypted before it leaves your device — in that mode, the server stores only ciphertext and never sees plaintext content.

We do not sell your data to third parties. Please review our Privacy Policy for full details on data collection and retention practices.

7. Intellectual Property

The service and its original content, features, and functionality are and will remain the exclusive property of Cyrush LLC and its licensors. The service is protected by copyright, trademark, and other laws. Our trademarks and trade dress may not be used in connection with any product or service without our prior written consent.

8. Subscriptions and Billing

Vistacker offers a free tier and a paid Pro plan. Pro subscriptions are billed annually via Stripe. By subscribing, you authorize Cyrush LLC to charge your payment method on a recurring basis until you cancel. Cancellation takes effect at the end of the current billing period. Refunds are issued at our discretion.

9. Disclaimer of Warranties

The service is provided on an "as is" and "as available" basis. Cyrush LLC makes no warranties, expressed or implied, and hereby disclaims all other warranties including without limitation, implied warranties or conditions of merchantability, fitness for a particular purpose, or non-infringement of intellectual property or other violation of rights.

10. Limitation of Liability

In no event shall Cyrush LLC or its suppliers be liable for any damages (including, without limitation, damages for loss of data or profit, or due to business interruption) arising out of the use or inability to use the service, even if Cyrush LLC has been notified of the possibility of such damage. Because some jurisdictions do not allow limitations on implied warranties or limitations of liability for consequential or incidental damages, these limitations may not apply to you.

11. Indemnification

You agree to defend, indemnify, and hold harmless Cyrush LLC and its officers, directors, employees, and agents for any losses, costs, liabilities, and expenses (including reasonable attorney's fees) relating to or arising out of your use of Vistacker, your violation of any terms of this agreement, your violation of any rights of a third party, or your violation of any applicable laws or regulations.

12. Termination

Either party may terminate this agreement at any time. Cyrush LLC may terminate or suspend your access to Vistacker at any time, with or without cause, with or without notice, effective immediately. Upon termination, your right to use Vistacker will cease immediately. Data deletion requests can be submitted by contacting us.

13. Governing Law

These terms and conditions are governed by and construed in accordance with the laws of the State of California, United States. You irrevocably submit to the exclusive jurisdiction of the courts in that jurisdiction.

14. Severability

If any provision of this agreement is held to be invalid or unenforceable, such provision shall be struck and the remaining provisions shall be enforced to the fullest extent under law.
