Legal
Terms of Service
Last updated: March 16, 2026
1. Acceptance of Terms
Welcome to Mindlockr. By accessing or using the Mindlockr website located at mindlockr.com or any related services (collectively, the “Service”), you agree to be bound by these Terms of Service (“Terms”). Please read them carefully.
If you do not agree to these Terms, you must not access or use the Service. By creating an account or continuing to use the Service, you confirm that you are at least 13 years of age (or 16 in the European Union) and have the legal capacity to enter into a binding agreement.
2. Description of the Service
Mindlockr is a memory-based mnemonic vault application that helps users create and recall personal visual associations for cryptocurrency seed phrases. The Service allows you to:
- Create encrypted vaults to store personal memory associations
- Upload and annotate images linked to mnemonic positions
- Practice recall through a guided review flow
- Access a public challenge puzzle
We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time, with or without notice, and without liability to you.
3. Zero-Knowledge Architecture
Mindlockr is designed as a zero-knowledge application. This means:
- ✓Your Master Password never leaves your device — we have no copy of it.
- ✓All encryption and decryption occurs in your browser using AES-256-GCM.
- ✓We store only encrypted ciphertext that we are technically unable to read.
- ✓Your seed phrase words are never transmitted to or stored on our servers.
4. Master Password — Critical Warning
If you lose your Master Password, your encrypted vault data is permanently and irrecoverably lost. Mindlockr cannot reset, recover, unlock, or bypass your Master Password under any circumstances — this is fundamental to the zero-knowledge design. You are solely and entirely responsible for remembering your Master Password or storing it securely offline. Mindlockr accepts no liability for data loss resulting from a forgotten or lost Master Password.
5. Account Registration & Security
To use the Service, you must register for an account using a valid email address or a Google account. You agree to provide accurate, current, and complete information during registration and to keep it up to date.
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to notify us immediately of any unauthorized use of your account.
We reserve the right to suspend or terminate accounts that we reasonably believe have been compromised, or that are being used in violation of these Terms.
6. Acceptable Use
You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:
- Use the Service for any purpose that is unlawful or prohibited by these Terms
- Violate any applicable local, national, or international law or regulation
- Upload, store, or transmit any content that is illegal, harmful, threatening, abusive, defamatory, or obscene
- Attempt to gain unauthorized access to any part of the Service, other accounts, or related systems
- Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the Service
- Use automated tools, bots, or scrapers to access or interact with the Service without our written permission
- Interfere with or disrupt the integrity, performance, or availability of the Service
- Impersonate any person or entity, or falsely state your affiliation with any person or entity
- Use the Service to transmit spam, chain letters, or other unsolicited communications
- Attempt to probe, scan, or test the vulnerability of the Service without authorization
We reserve the right to terminate your access to the Service for any violation of this section.
7. User Content
“User Content” means any images, notes, vault names, or other materials you upload or create through the Service.
You retain all ownership rights to your User Content. By uploading User Content, you grant Mindlockr a limited, non-exclusive, royalty-free license solely to store, process, and serve your content for the purpose of providing the Service to you. Because vault content is encrypted client-side, we cannot and do not access or review it.
You represent and warrant that you own or have the necessary rights to the User Content you upload, and that it does not infringe any third-party intellectual property, privacy, or other rights.
8. Free Tier & Service Limits
The free tier of Mindlockr allows up to 3 vaults per account. We reserve the right to modify service limits, introduce paid plans, or adjust features at any time. We will provide reasonable notice of any changes that materially affect existing users.
9. Intellectual Property
The Service and its original content (excluding User Content), including but not limited to the Mindlockr name, logo, website design, text, graphics, and software, are owned by Mindlockr and are protected by applicable intellectual property laws. You may not copy, modify, distribute, sell, or lease any part of the Service without our prior written consent.
10. Third-Party Links & Services
The Service may contain links to third-party websites or services that are not owned or controlled by Mindlockr. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites. We encourage you to review the terms and privacy policies of any third-party services you visit.
11. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
Mindlockr does not warrant that the Service will be uninterrupted, error-free, secure, or free of viruses or other harmful components. We do not warrant that any data stored through the Service will not be lost, corrupted, or accessed by unauthorized parties.
The Service is intended as a memory-aid tool. It is not a substitute for proper offline backup of your seed phrase. You are solely responsible for maintaining independent, secure backups of any critical information.
12. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, MINDLOCKR 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 cryptocurrency, digital assets, or funds of any kind
- Loss of data or vault content
- Loss of profits or revenue
- Loss arising from forgotten or lost Master Password
- Any unauthorized access to your account or data
IN NO EVENT SHALL OUR TOTAL LIABILITY TO YOU EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO USE THE SERVICE IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) USD $10.
Some jurisdictions do not allow exclusion of implied warranties or limitation of liability for incidental or consequential damages, so some of the above limitations may not apply to you.
13. Indemnification
You agree to indemnify, defend, and hold harmless Mindlockr and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in connection with your use of the Service, your User Content, or your violation of these Terms.
14. Termination
You may delete your account at any time by contacting us. Upon deletion, your account data and encrypted vault content will be permanently removed from our systems within 30 days. Because your vault data is encrypted with your Master Password, deleted data cannot be recovered by anyone.
We may suspend or terminate your account and access to the Service immediately, without prior notice or liability, if we reasonably believe you have violated these Terms. Upon termination, your right to use the Service ceases immediately.
15. Governing Law & Disputes
These Terms shall be governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles. Any dispute arising out of or relating to these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If unresolved, disputes shall be submitted to binding arbitration under the rules of the American Arbitration Association, except that either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent irreparable harm.
16. Changes to These Terms
We may revise these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page. For material changes, we will notify registered users by email or by displaying a prominent notice on the Service at least 7 days before the change takes effect. Your continued use of the Service after the effective date constitutes your acceptance of the revised Terms.
