Terms of Service

1. Agreement to Terms

By accessing or using Supaboard (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you must not use the Service.

The Service is operated by Printelangelo, a sole proprietorship based in Vancouver, British Columbia, Canada ("Operator," "we," "us," or "our").

Your continued use of the Service following the posting of revised Terms means you accept and agree to the changes.

2. Eligibility

You must be at least 13 years of age to use the Service. By creating an account, you represent that you are at least 13 years old and, if you are under the age of majority in your jurisdiction, that you have obtained parental or guardian consent to use the Service.

You must provide accurate, complete, and current information during registration and keep your account information updated. You are responsible for safeguarding your password and for all activities that occur under your account. You must notify us immediately of any unauthorized use of your account. One account per person; account sharing is prohibited.

We reserve the right to refuse registration, suspend, or terminate any account at our sole discretion, with or without notice, for any reason or no reason.

3. The Service

Supaboard is a web-based whiteboard application for creating system design diagrams. The Service includes a canvas editor with system design components, board management, a public gallery, export functionality, collaboration features, practice session tracking, and subscription management.

The Service is offered in two tiers:

• Free: limited to 1 board, all system components, PNG export, and community support.
• Pro ($12/month): unlimited boards, premium shape library, export to PNG/SVG/PDF, collaborator invites, and priority support.

The specific features, functionality, and user interface of the Service may change at any time without prior notice. We do not guarantee that any particular feature will remain available.

4. Subscriptions and Billing

4.1 Free Tier

The Free tier provides limited access at no cost. Free tier limitations may change at our discretion. No payment information is required.

4.2 Pro Subscription

Pro subscriptions are billed on a recurring monthly basis. All payments are processed by Stripe, Inc. We do not directly store payment card information.

4.3 Auto-Renewal

YOUR SUBSCRIPTION WILL AUTOMATICALLY RENEW AND YOU WILL BE CHARGED THE THEN-CURRENT SUBSCRIPTION FEE UNLESS YOU CANCEL BEFORE THE END OF THE CURRENT BILLING PERIOD. YOU MAY CANCEL AT ANY TIME THROUGH YOUR ACCOUNT SETTINGS.

4.4 Cancellation

You may cancel your subscription at any time through the billing portal accessible from your account settings. Cancellation takes effect at the end of the current billing period. Upon cancellation, you retain Pro features until the end of the paid period, then revert to the Free tier. Existing boards beyond the Free tier limit become read-only.

4.5 Refund Policy

All subscription payments are non-refundable except as required by applicable law. No refunds are provided for partial billing periods, downgrades, or unused time. If you are a resident of the European Union, you may be entitled to a refund within 14 days of your initial subscription under the EU Consumer Rights Directive. By subscribing, you agree that the digital service begins immediately and you acknowledge that this may affect your withdrawal rights under applicable law.

4.6 Price Changes

We reserve the right to change subscription pricing at any time. Price increases for existing subscribers will take effect at the next renewal period following at least 30 days' notice. Your continued use after a price change constitutes acceptance of the new pricing.

5. Intellectual Property

5.1 Service Ownership

The Service, including all software, design, text, graphics, interfaces, custom system design shapes, and the selection and arrangement thereof, is owned by the Operator and protected by intellectual property laws. The "Supaboard" name, logo, and branding are the Operator's property.

5.2 User Content Ownership

You retain ownership of the content you create using the Service ("User Content"), including board diagrams, titles, descriptions, tags, and thumbnails.

5.3 License Grant to the Operator

By creating User Content on the Service, you grant us a worldwide, non-exclusive, royalty-free, sublicensable license to use, reproduce, modify, adapt, publish, and display such User Content solely in connection with operating and providing the Service.

For content you publish to the public gallery, this license extends to displaying your content in the gallery and in promotional materials. This license for published gallery content survives termination of your account.

5.4 Feedback

Any feedback, suggestions, or ideas you provide regarding the Service become our property and may be used without any obligation of compensation to you.

6. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any applicable law.
• Upload, publish, or transmit content that is defamatory, obscene, abusive, threatening, or otherwise objectionable.
• Infringe on any third party's intellectual property, privacy, or other rights.
• Use the Service to store or transmit malicious code, malware, or harmful content.
• Attempt to gain unauthorized access to the Service, other accounts, or connected systems.
• Reverse engineer, decompile, or disassemble any aspect of the Service.
• Use automated scripts, bots, or scrapers to access the Service without our written permission.
• Circumvent subscription limitations or feature gating, including creating multiple accounts to bypass Free tier limits.
• Manipulate engagement metrics (likes, bookmarks, views) through automated or fraudulent means.
• Share account credentials or allow multiple individuals to use a single account.
• Use the Service to compete with us or build a competing product.

For the public gallery specifically, published boards must be original work or properly attributed, relevant to system design, and must not contain personally identifiable information of third parties or confidential information belonging to a third party (such as proprietary architectures from an employer).

7. Content Moderation and Gallery Publishing

Boards submitted for publication to the public gallery require approval before appearing publicly. We reserve the sole and absolute right to approve, reject, feature, or remove any content from the public gallery at any time, for any reason. We are not obligated to provide reasons for our moderation decisions.

We reserve the right, but have no obligation, to monitor User Content. We may remove any User Content at any time, for any reason, without notice. Violations may result in content removal, account suspension, or permanent termination.

8. Collaboration

Board owners may invite collaborators with view or edit permissions. The board owner remains the sole owner of the board and all content therein. Contributions by collaborators to a shared board become part of the board owner's User Content, subject to the license granted to us in Section 5.3.

The board owner has full control over the board, including the right to remove collaborators, delete the board, or publish it to the gallery. We are not a party to any arrangement between board owners and collaborators and disclaim any liability arising from collaborative use of the Service.

9. Artificial Intelligence Features

The Service may introduce AI-powered features in the future, including automated suggestions, diagram analysis, or content generation. AI-generated output will be provided "as-is" for informational purposes only and should not be relied upon as professional engineering or architectural advice.

Supaboard is an educational and practice tool. It is not a substitute for professional system design review. You acknowledge that AI features may produce inaccurate or incomplete results, and you are solely responsible for evaluating and using any AI-generated output.

10. Privacy

Your use of the Service is also governed by our Privacy Policy, which is incorporated by reference into these Terms. Please review the Privacy Policy to understand how we collect, use, and protect your personal information.

11. Service Availability

THE SERVICE IS PROVIDED ON AN "AS AVAILABLE" BASIS. WE DO NOT GUARANTEE THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE.

No Service Level Agreement (SLA) is provided. We reserve the right to modify, suspend, or discontinue the Service (or any part thereof) at any time, with or without notice, for any reason. We may perform maintenance that temporarily disrupts access. The auto-save and version conflict resolution system is provided on a best-effort basis and is not a guarantee against data loss.

12. Account Termination

12.1 By You

You may delete your account at any time through the Settings page. Upon deletion, your profile is marked for removal and your data becomes inaccessible. Data is permanently purged after 90 days. Active subscriptions are cancelled upon account deletion.

12.2 By Us

We may terminate or suspend your account and access to the Service immediately, without prior notice or liability, for any reason whatsoever, including without limitation if you breach these Terms.

12.3 Effects of Termination

Upon termination, your right to use the Service ceases immediately. The license granted to us for published gallery content survives termination. No refund of prepaid subscription fees is provided upon termination for cause. Sections that by their nature should survive termination shall survive, including intellectual property, limitation of liability, indemnification, and dispute resolution.

13. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, 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 MEET YOUR REQUIREMENTS, THAT RESULTS OBTAINED FROM THE SERVICE WILL BE ACCURATE OR RELIABLE, THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT DEFECTS WILL BE CORRECTED.

WE DO NOT WARRANT THAT SYSTEM DESIGN DIAGRAMS CREATED USING THE SERVICE ARE TECHNICALLY CORRECT, COMPLETE, OR SUITABLE FOR PRODUCTION USE. THE SERVICE IS AN EDUCATIONAL AND PRACTICE TOOL.

Some jurisdictions do not allow the exclusion of implied warranties, so the above exclusions may not apply to you. In such jurisdictions, our warranties are limited to the maximum extent permitted by law.

14. Limitation of Liability

IN NO EVENT SHALL THE OPERATOR BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, REGARDLESS OF THE THEORY OF LIABILITY.

THE OPERATOR'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE AMOUNTS PAID BY YOU TO THE OPERATOR IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED CANADIAN DOLLARS (CAD $100).

This limitation of liability does not apply to liability arising from our gross negligence or willful misconduct, or death or personal injury resulting from our negligence, to the extent such limitation is prohibited by applicable law. Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so the above limitation may not apply to you.

15. Indemnification

You agree to defend, indemnify, and hold harmless the Operator from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including attorney's fees) arising from:

• Your use of the Service.
• Your violation of these Terms.
• Your User Content, including any content published to the gallery.
• Your violation of any third-party rights, including intellectual property rights.
• Any claim that your User Content caused damage to a third party.
• Any dispute between you and other users of the Service.

The Operator has the right to assume exclusive defense and control of any matter subject to indemnification. You shall not settle any claim without the Operator's prior written consent. This indemnification obligation survives the termination of these Terms.

16. Dispute Resolution

16.1 Informal Resolution

Before filing any formal proceeding, you agree to attempt to resolve the dispute by contacting us at support@supaboard.app. We will attempt to resolve the dispute informally within 30 days.

16.2 Binding Arbitration

If a dispute cannot be resolved informally, all disputes arising out of or relating to these Terms or the Service shall be resolved by binding individual arbitration conducted in Vancouver, British Columbia, Canada, or remotely via telephone, video, or online proceedings. The arbitrator's award shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.

16.3 Class Action Waiver

YOU AND THE OPERATOR AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING.

To the extent this class action waiver is found to be unenforceable in your jurisdiction, it shall not apply to you and the dispute shall be resolved in the courts specified in Section 16.5.

16.4 Small Claims Exception

Either party may bring claims within the jurisdiction of the British Columbia Civil Resolution Tribunal or equivalent small claims court if the claims qualify.

16.5 Opt-Out

You may opt out of the arbitration and class action waiver provisions by notifying us in writing within 30 days of first using the Service. If you opt out, disputes will be resolved in the courts of the Province of British Columbia, Canada, and you consent to personal jurisdiction in those courts.

17. Copyright Policy

We respect intellectual property rights and expect our users to do the same. If you believe that content on the Service infringes your copyright, you may submit a takedown notice to support@supaboard.app including:

• Identification of the copyrighted work claimed to be infringed.
• Identification of the infringing material and its location.
• Your contact information.
• A statement of good faith belief that the use is not authorized.
• A statement, under penalty of perjury, that the information is accurate and you are authorized to act on behalf of the copyright owner.
• Your physical or electronic signature.

We will review valid takedown requests and may remove content at our discretion. Users who believe content was wrongly removed may submit a counter-notification. We will terminate the accounts of repeat infringers.

18. Force Majeure

We shall not be liable for any delay or failure to perform resulting from causes outside our reasonable control, including but not limited to: acts of God, natural disasters, pandemics, war, terrorism, government actions, Internet or infrastructure failures, power outages, third-party service provider failures (including Supabase, Stripe, our hosting provider, or any OAuth identity provider), cyberattacks, or labor disputes.

19. Third-Party Services

The Service integrates with and depends on third-party services including Supabase (authentication and database), Stripe (payment processing), and third-party OAuth providers (Google and GitHub). We are not responsible for the availability, accuracy, or content of any third-party services. Your use of third-party services is governed by their own terms and policies. We are not liable for any loss or damage arising from third-party service failures, changes, or discontinuation.

20. General Provisions

Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Province of British Columbia and the federal laws of Canada applicable therein, without regard to conflict of law provisions.

Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable.

Entire Agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Operator regarding the Service.

Waiver

No waiver of any term shall be deemed a further or continuing waiver. Our failure to enforce any right or provision shall not be deemed a waiver.

Assignment

You may not assign these Terms without our prior written consent. We may assign these Terms freely, including in connection with a merger, acquisition, or sale of assets.

Amendments

We reserve the right to modify these Terms at any time. For material changes that adversely affect your rights, we will provide at least 30 days' notice. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms. If you do not agree, your sole remedy is to discontinue use and delete your account.

International Users

The Service is operated from Canada. Users accessing the Service from outside Canada are responsible for compliance with local laws. To the extent required by applicable law, nothing in these Terms limits your statutory rights as a consumer. Where these Terms conflict with mandatory local law, the mandatory local law shall prevail to the minimum extent necessary.

Notices

Notices to you may be made via email to the address associated with your account or by posting on the Service. Notices to us must be sent to support@supaboard.app.
