1. Introduction

Welcome to Matej Vavro Productivity ("we", "our", or "us"). These Terms of Service ("Terms") govern your access to and use of our website, content, products, and services (collectively, the "Services").

By accessing or using our Services, you agree to be bound by these Terms. If you do not agree to these Terms, please do not use our Services.

Important: Matej Vavro Productivity is an independent, third-party business. We are not affiliated with, endorsed by, or sponsored by Obsidian (Dynalist Inc.). Our plugins are third-party community plugins. All references to "Obsidian" on this website are for descriptive and compatibility purposes only.

2. Acceptance of Terms

By using our Services, you represent that:

You are at least 18 years old or have parental/guardian consent
You have the legal capacity to enter into these Terms
You will comply with all applicable laws and regulations
All information you provide is accurate and current

3. Services Description

We provide the following Services:

Educational Content: Articles, tutorials, guides, and videos about productivity, note-taking, and personal knowledge management
Software Tools: Obsidian plugins and other productivity tools, available as free (open-source) and commercial (paid) products
Paid Products: Commercial software licenses available as one-time purchases or subscriptions, with license key activation
Community Resources: Access to documentation, examples, and support materials
Support Services: Optional support through Ko-fi and GitHub Sponsors, and priority support for paid customers

We reserve the right to modify, suspend, or discontinue any part of our Services at any time without prior notice.

4. No Professional Advice

The content provided through our Services is for educational and informational purposes only. It does not constitute professional, legal, financial, or technical advice.

You should not rely solely on our content for making decisions that could affect your business, finances, data security, or legal obligations. Always consult with qualified professionals when needed.

You use the information, workflows, and tools at your own risk. We are not responsible for any outcomes resulting from following our recommendations or using our content.

5. User Accounts and Responsibilities

Certain Services, including purchasing products and managing subscriptions, require you to create an account on our website (via email/password or GitHub OAuth). You are responsible for:

Providing accurate and current information during registration
Maintaining the confidentiality of your account credentials
All activities that occur under your account
Notifying us immediately of any unauthorized access
Complying with the terms of service of third-party platforms (GitHub, Ko-fi, YouTube)

Password and Security

Sensitive account operations — including changing your email address, changing your password, and deleting your account — require you to confirm your current password. This protects your account from unauthorized changes, even if your session is active.

Account Deletion

You may delete your account at any time from your account settings page. Account deletion is immediate, permanent, and irreversible. When you delete your account:

Your user profile, authentication data, and session are permanently removed
All active subscriptions are cancelled immediately — you lose access to paid features right away, even if you had remaining time in your billing period
All license keys associated with your account are revoked and can no longer be used to activate products
All entitlements (product access rights) are permanently removed
Associated billing data may be retained as required by law
This action cannot be undone — there is no recovery period or grace window

Account deletion does not entitle you to a refund for previously purchased products, unused subscription time, or active subscriptions. Billing and transaction records may be retained as required by applicable tax and accounting laws (see our Privacy Policy).

We encourage this self-service option for users who wish to exercise their right to erasure under GDPR. You may also request account deletion by contacting us at hello@matejvavroproductivity.com.

6. Acceptable Use

You agree NOT to use our Services to:

Violate any applicable laws or regulations
Infringe on intellectual property rights of others
Transmit malicious code, viruses, or harmful software
Attempt to gain unauthorized access to our systems
Harass, abuse, or harm other users
Distribute spam or unsolicited communications
Reverse engineer or decompile our software (except where permitted by license)
Use our Services for commercial purposes without authorization
Scrape or extract data using automated means without permission (this does not apply to standard search engine indexing or lawful archiving)

7. Intellectual Property

Our Content

All content on this website, including text, graphics, logos, images, videos, and software, is the property of Matej Vavro or its licensors and is protected by copyright and other intellectual property laws.

Open Source Software

Some of our software tools are released under open-source licenses (MIT, GPL, etc.). These tools are governed by their respective license terms, which take precedence over these Terms for those specific tools.

User-Generated Content

If you submit content to us (comments, feedback, suggestions), you grant us a non-exclusive, worldwide, royalty-free license to use, modify, and distribute that content for the purpose of improving our Services.

8. Software and Tools

License Grant

We grant you a limited, non-exclusive, non-transferable license to use our software tools in accordance with their respective licenses.

Commercial Use

Unless otherwise stated in a specific license, our tools may be used for both personal and commercial purposes. Open-source tools are governed by their respective licenses (MIT, GPL, etc.), which take precedence over these Terms for those specific tools.

For Obsidian plugins and other productivity tools:

You may use them in personal and professional/business contexts
You may use them in company/enterprise environments
Check the specific license file (LICENSE.md) in each tool's repository for exact terms
If you have questions about commercial use, contact us at hello@matejvavroproductivity.com

Warranty Disclaimer

Our software and tools are provided "AS IS" without warranty of any kind, either express or implied, including but not limited to:

Merchantability or fitness for a particular purpose
Non-infringement of third-party rights
Uninterrupted, secure, or error-free operation
Data accuracy, integrity, or security

Data Backup

You are solely responsible for backing up your data. We are not liable for any data loss resulting from the use of our tools.

Offline License Verification

Our commercial Obsidian plugins periodically verify license validity with our servers. Limited technical information is transmitted for license enforcement. Offline use may require periodic revalidation. Each license key supports activation on up to 5 devices simultaneously.

Plugin Telemetry (Server-Side Only)

Our Obsidian plugins do not include client-side telemetry or analytics. During license verification, limited technical information such as plugin version, device identifier, and platform information may be transmitted. No vault content, note content, or personal files are ever transmitted.

This data is used for license validation, activation management, and product improvement. This telemetry is a required part of our commercial plugin service. You can request deletion of your telemetry data by contacting us or by deleting your account. For full details, see our Privacy Policy.

9. Payments, Subscriptions, and Refunds

Paid Products

We offer commercial software products available as:

One-time purchases: A single payment for lifetime access to the product (e.g., Notes Manipulator Pro).
Subscriptions: Recurring monthly or annual payments for continued access (e.g., Prisma Calendar Pro). Some subscriptions include a free trial period.

Payment Processing

All payments are processed securely by Stripe. By making a purchase, you agree to Stripe's Terms of Service. We do not store your credit card details — Stripe handles all sensitive payment information on their certified infrastructure.

Prices and Currency

All prices are displayed in USD. Prices are subject to change, but changes will not affect existing active subscriptions until renewal. We currently do not charge VAT. If this changes in the future, prices and invoices will be updated accordingly.

Free Trials

Some subscriptions offer a free trial period. You will not be charged during the trial. If you do not cancel before the trial ends, your subscription will automatically convert to a paid subscription at the advertised price. You may cancel at any time during the trial from your account page.

License Keys

Upon purchase, you will receive a license key to activate the product. License keys are personal, non-transferable, and subject to activation limits as stated on the product page. We reserve the right to revoke license keys in cases of abuse, fraud, or violation of these Terms.

Subscription Cancellation

You may cancel your subscription at any time from your account page or via the Stripe customer portal. Upon cancellation:

You retain access until the end of your current billing period
No further charges will be made
No partial refunds are given for unused time in the current billing period

Refund Policy

Subscriptions: You may cancel your subscription at any time from your account settings. Cancellation stops future billing, but the current billing period is non-refundable. If you cancel during a free trial, you will not be charged.
One-time purchases: All one-time purchases are final and non-refundable. Our products are digital goods delivered immediately after purchase in the form of license keys or software access. Because the product is supplied instantly, refunds cannot be provided.
EU right of withdrawal (digital content): By completing the purchase, you expressly request immediate delivery of digital content that is not supplied on a physical medium, and you acknowledge that you lose your right of withdrawal once the performance has begun. This is in accordance with Article 16(m) of Directive 2011/83/EU on consumer rights.

Voluntary Donations

Donations and sponsorships through Ko-fi and GitHub Sponsors are voluntary, separate from product purchases, and non-refundable unless required by law. Donations do not guarantee priority support, feature implementation, or continued availability of any Service.

10. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for:
