Terms of Service

Agreement

These terms govern your use of Szum, operated by Bartosz Prusinowski, based in Zürich, Switzerland. By creating an account, purchasing a plan, or otherwise using Szum, you agree to these terms and our Privacy Policy. If you do not agree, do not use the service.

If you use Szum for an organization, you confirm that you have authority to accept these terms on its behalf. You must be at least 16 years old and legally able to enter into this agreement.

The service

Szum is a chart design and rendering service. It includes the web editor and Studio, chart image API, saved and published charts, interactive embeds, Figma plugin, MCP server, SDK, documentation, and related account and billing features.

Features differ by plan and may carry technical, storage, usage, or rate limits. The current limits and feature comparison are listed in Plans & Limits. Documentation is part of the service description, but these terms control if there is a conflict.

Accounts and credentials

• Provide accurate and current account information.
• Keep your password, API keys, session, and MCP authorizations secure. Do not publish or share credentials.
• You are responsible for activity performed through your account or credentials, except to the extent caused by Szum.
• Notify us promptly and revoke affected credentials if you suspect unauthorized access.
• Do not create accounts or rotate credentials to evade limits, suspension, or enforcement.

If you connect Szum to Figma, GitHub, or an MCP client, your use of that third-party product is also governed by its terms. You are responsible for the clients you authorize and for requests they submit to Szum on your behalf.

Plans, subscriptions, and billing

• Anonymous and Free use is available subject to the limits shown in the service. Free features may be changed or withdrawn.
• Paid subscriptions are processed by Stripe and renew automatically for the selected monthly or annual billing period until cancelled.
• Prices, billing interval, currency, and applicable taxes are shown before checkout. You authorize Stripe and Szum to charge the payment method associated with your subscription.
• Pro users may opt into usage-based overage billing. Once enabled, eligible usage beyond the included allowance is charged at the rate shown when overage is enabled and on the pricing page.
• You can cancel from your account. Unless stated otherwise at the time of cancellation, access continues until the end of the paid billing period and the subscription then stops renewing.
• Payments are non-refundable and we do not provide credits for partial periods, unused allowance, downgrades, or account termination, except where required by law or expressly agreed.

We may change prices prospectively. For an existing paid subscription, we will provide reasonable notice before a price change applies to a future renewal where required by law. If payment fails, we may retry the charge, restrict paid features, downgrade, or suspend the account.

Usage, storage, and attribution

A render is one successful chart output produced when a request reaches Szum, including an image, editor export, fresh embed response, or MCP preview. Cached views, local previews, Figma canvas rendering, validation, saving, and client-side interactions do not count.

Monthly render allowances reset on the first day of each month in UTC. Rate limits and storage limits apply in addition to render allowances. Requests may be rejected when a limit is reached. We may adjust limits to protect the service, prevent abuse, or reflect a plan change.

Saved chart image and embed URLs use edge caching. Only requests that reach Szum and successfully produce a fresh output count against the chart creator's allowance; cache hits do not. A popular, uncached, or repeatedly updated chart may therefore consume the creator's usage.

Free and anonymous Szum-served renders may include a “made with Szum” credit. Creator and Pro renders omit it by default. Locally rendered Figma assets are not branded. The current attribution behavior is described in Plans & Limits.

Your content

You retain ownership of chart configurations, data, text, and other content you submit, and of rendered output to the extent permitted by law. You are responsible for your content, its accuracy, and having the rights and lawful basis needed to use it.

You grant Szum a non-exclusive, worldwide, royalty-free license to host, copy, process, render, cache, transmit, and display your content only as needed to provide, secure, operate, and maintain the service. This license lasts for as long as the content is stored or cached and includes using service providers for those purposes. It does not give Szum ownership of your content.

Do not submit content that is unlawful, infringes intellectual property, privacy, publicity, or other rights, contains malware, or exposes information you are not permitted to disclose. We may remove or disable content when reasonably necessary to comply with law, enforce these terms, or protect Szum or others.

Saved and published charts

Drafts are private to the account that owns them. Publishing a chart creates image, embed, and chart-page URLs that can be opened by anyone who has the opaque link. These links are not access-controlled and must not be used for confidential information. An embed or chart page may expose its chart configuration to the viewer's browser.

You authorize Szum to serve and cache published charts until you unpublish or delete them. Unpublishing or deletion stops new origin access, but an existing response may remain available in edge caches for a limited time. You are responsible for distributing and managing published links.

Saved charts are subject to storage limits. A downgrade does not automatically unpublish existing charts, but it may prevent new saves or updates until usage is within the new plan's limits. Existing public charts may use the themes, fonts, and attribution available on the current plan; upgrading again may restore paid presentation. We do not guarantee permanent storage; keep your own copy of important chart configurations and output.

Acceptable use

You must not:

• Use Szum for unlawful, fraudulent, or deceptive activity
• Infringe or facilitate infringement of another person's rights
• Access another user's account, charts, or credentials without authorization
• Bypass authentication, quotas, rate limits, storage limits, or other technical protections
• Probe, scan, or test vulnerabilities without written permission
• Introduce malware or interfere with the operation or availability of the service
• Place an unreasonable load on Szum or use automated traffic in a way that harms other users
• Resell or provide Szum itself as a standalone competing chart rendering service without our written agreement
• Reverse engineer non-public service components except to the extent the restriction is prohibited by law

Szum materials

Szum and its licensors retain all rights in the service, including its software, renderer, visual system, themes, documentation, branding, and interfaces. These terms give you a limited, non-exclusive, non-transferable, revocable right to use the service while you comply with them. Separate software packages may be governed by the license distributed with that package.

You may use chart output commercially. Your plan determines any attribution automatically included in Szum-served output. This right remains subject to these terms and any rights belonging to third parties in the data or other material you supplied. You may not use Szum's name or marks to imply sponsorship or endorsement.

Changes and availability

We may add, change, or remove features, APIs, limits, or integrations. We will try to provide reasonable notice before a material change that adversely affects a paid service, unless an immediate change is needed for security, legal, or operational reasons.

The service may be unavailable because of maintenance, outages, third-party failures, or other causes. Unless we agree to a separate service-level agreement, we do not guarantee uninterrupted or error-free availability. Current incidents may be shown on our status page.

Suspension and termination

We may restrict, suspend, or terminate access if you materially breach these terms, fail to pay amounts due, create security or legal risk, or use the service in a way that could harm Szum or others. Where reasonable, we will provide notice and an opportunity to resolve the issue.

You may delete your account from account settings. Deletion is permanent, cancels active subscriptions, revokes credentials, and removes access to saved charts. Associated storage cleanup is asynchronous, and cached published responses may remain available for a limited time as described in the Privacy Policy.

Provisions that by their nature should survive termination remain in effect, including payment obligations, ownership, disclaimers, liability limits, and dispute terms.

Disclaimers

To the maximum extent permitted by law, Szum is provided “as is” and “as available.” We disclaim implied warranties of merchantability, fitness for a particular purpose, non-infringement, and accuracy. You are responsible for reviewing chart data, labels, calculations, accessibility, and output before relying on or publishing it.

We are not responsible for third-party services, clients, fonts, integrations, or content. Nothing in these terms limits rights or warranties that cannot lawfully be excluded.

Limitation of liability

To the maximum extent permitted by law, Szum and its operator will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, data, goodwill, or business opportunity arising from the service.

To the maximum extent permitted by law, our total liability arising from the service or these terms is limited to the amount you paid to Szum during the 12 months before the event giving rise to the claim. These exclusions and limits do not apply to liability that cannot be excluded or limited under applicable law.

Changes to these terms

We may update these terms as the service changes. We will update the date at the top and provide reasonable advance notice of material changes to registered users. Changes required for legal, security, or abuse-prevention reasons may take effect sooner. Continuing to use Szum after updated terms take effect means you accept them.

Governing law

These terms are governed by Swiss law, without regard to conflict-of-law principles. Courts in Zürich, Switzerland have jurisdiction, except where mandatory consumer law gives you the right to use another law or forum.
