Terms of Service

KMind Zen Terms of Service

These Terms govern your use of KMind Zen Desktop for macOS, the website, Web services and plugins, optional accounts, purchases, and entitlement restoration through the App Store, orders, or account access.

Effective date: 2026-03-12 · Last updated: 2026-07-11 · Operator: ZIHAO SONG · Contact: kmind_app@outlook.com

1. Service scope and acceptance

KMind Zen is operated by ZIHAO SONG. By accessing, creating an account for, purchasing, or using KMind Zen, you agree to these Terms.

If you use the service on behalf of an organization, you confirm that you have authority to accept these Terms for that organization.

2. Accounts, purchases, and renewals

A KMind account is not required to buy lifetime access to KMind Zen Standalone Pro through the Mac App Store or activate it on the purchasing Mac. Apple’s App Store services process that purchase, and Apple manages the payment method, billing, and applicable refund process through its own channels and rules.

KMind Zen Standalone Pro covers eligible standalone desktop and mobile apps within the purchased seat allowance; it does not include the SiYuan or Obsidian plugins. Mobile use, seat management, and cross-device restoration require linking the purchase to the same KMind account. Plugin entitlements remain available through their own products or an offer such as Founders Pass when explicitly stated.

For website or other purchase flows that explicitly request an email address, you are responsible for providing one that can receive order records, service communications, and recovery information.

If a plan is identified as a subscription at checkout, it will renew on the billing cadence shown at checkout unless cancelled before the next renewal date.

Except where required by law, expressly stated at checkout, or otherwise agreed in writing, fees for digital entitlements are generally non-refundable once access or licensing assets have been delivered.

3. Licensing, permitted use, and recovery

Your purchase gives you a limited right to use KMind Zen within the scope of the plan or license you obtained. It does not transfer ownership of the software, service, brand, or source code.

You must not resell, leak, share, bypass, or misuse licensing assets, access restrictions, or service flows in ways that violate law or these Terms.

Restore a Mac App Store purchase through Restore purchases in the desktop app. The Mac App Store build has no external purchase link, activation-key entry, or self-update flow. An optional KMind account only restores an existing account entitlement or links a completed App Store purchase.

Other website and plugin entitlements continue to use the recovery path described by their checkout, order history, and account assets, and should not be confused with Mac App Store restoration.

4. Service changes, availability, and disclaimers

We may update features, pricing, payment methods, messaging, or service structure as the product evolves, for security reasons, or to comply with legal or operational requirements.

We aim to keep KMind Zen available and reliable, but we do not guarantee uninterrupted, error-free, or fully lossless operation in every environment.

Desktop project files are stored where you choose. You are responsible for maintaining appropriate backups and preserving a recoverable copy before import, overwrite, or migration operations.

5. Liability and disputes

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential losses such as lost profits, lost business opportunities, or data loss. If mandatory law limits how far liability can be excluded, those limits apply.

These Terms are generally governed by the laws applicable where the service operator is established, and disputes are generally handled by the competent courts or dispute resolution bodies where the service operator is established, unless mandatory consumer protection law requires otherwise.
