Terms of Use

• “Isotop”, “the Service” — the Isotop product: the web application at isotop.app, the Isotop Figma plugin, and their features, including the Collider AI design-system assistant.
• “Island AI Ltd”, “we”, “us”, “our” — the operator and provider of Isotop (see §1).
• “Polar” — Polar, the third party that acts as merchant of record / authorized reseller for paid purchases (see §6). Polar is not us.
• “you”, “your” — the person who accepts these Terms and uses the Service (see §3–§4).
• “Content” — anything you upload to, create in, or process through the Service, including design files, design-system data, images, text, and prompts you submit to Collider.

Isotop is operated and provided by Island AI Ltd, a company established in Ras Al Khaimah, United Arab Emirates (Commercial/Business License No. 07101832).

• Registered address: Office A, Innovation City Business Centre, RAK BANK ROC Office, Ground Floor, Al Riffa, Sheikh Mohammed Bin Zayed Road, Ras Al Khaimah, United Arab Emirates.
• Contact / support: support@isotop.app (you may also use the in-product support form, which reaches the same team).

Island AI Ltd is the party responsible to you under these Terms. For paid purchases, the merchant of record is Polar, not Island AI Ltd (see §6).

These Terms of Use are a binding agreement between you and Island AI Ltd governing your access to and use of the Service. Our Privacy Policy and Cookie Policy are incorporated by reference.

By creating an account, or by otherwise accessing or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms. If you do not agree, do not use the Service.

• Changes to these Terms. We may update these Terms. Each version carries its own version identifier and effective date. For material changes we will provide notice by a reasonable means (for example, in-product or by email), and, where required by law or where a material change to your agreement makes it appropriate, we will ask you to accept the updated Terms before continuing to use affected features. Your continued use after an update takes effect means you accept the updated Terms, except where applicable law requires express re-acceptance.

The Service is intended for adults aged 18 or older. By using the Service you represent that you are at least 18 and have the legal capacity to enter into these Terms. The Service is not directed to, or intended for, children, and we do not knowingly allow anyone under 18 to create an account. If you believe a minor has used the Service, contact support@isotop.app.

• Personal account. Accounts are personal to you. You may not share your credentials or account access with anyone else, and you may not let others use your account. You are responsible for all activity that occurs under your account.
• Account security. Keep your login credentials confidential and secure. Tell us promptly at support@isotop.app if you suspect unauthorized access.
• Accurate information. Provide accurate account information and keep it current.
• Authority for content you submit. You may use the Service with content owned by an employer, client, or other third party only where you have all necessary rights, permissions, and authority to do so. You are responsible for ensuring you are authorized to submit that content to the Service and to have it processed as described in these Terms and the Privacy Policy. If you use the Service on behalf of an organization, you represent that you are authorized to accept these Terms for that organization.
• Deleting your account. You may delete your account from the Service’s privacy/security settings. Deletion removes account-controlled data as described in the Privacy Policy; some records (for example, billing and tax records) may be retained where we are required or permitted to keep them, and copies held by third-party providers are handled as described in the Privacy Policy.

Isotop provides tools to build, preview, and manage design systems, delivered through a web application and a Figma plugin, and includes the Collider AI assistant.

• Figma plugin. The Isotop Figma plugin runs inside Figma and reads from and writes to your Figma design content in response to your actions in order to provide the features you use. Your use of Figma is also governed by Figma’s own terms; you are responsible for complying with them and for having the right to use the plugin with the files you open.
• Collider sessions and autosave. When you are signed in and have made progress in a Collider session (for example, accepted a step or completed a session), the Service automatically saves your session data and progress — including the session state and its chat history — so you can recover, reopen, and continue your work. This automatic saving is disclosed in the product. You can delete a saved session using the in-product session-deletion controls; deleting a session removes that session’s stored data as described in the Privacy Policy.
• Availability and changes. We may add, change, remove, or discontinue features of the Service, and we may impose or change limits (for example, usage or rate limits) as needed to operate the Service reliably. We aim to keep the Service available but do not promise uninterrupted or error-free operation.
• Support. Support is provided on a reasonable-efforts basis through support@isotop.app and the in-product support channels.

• Plans. There is a Free plan and one paid subscription plan. Exactly one paid package is purchasable at launch. Plan allowances (including AI credits) are as configured for each plan and shown in the product.
• Merchant of record. Paid purchases are sold and processed through Polar, which acts as the merchant of record / authorized reseller for the transaction. Polar handles payment, tax calculation and collection, invoicing, and receipts. Island AI Ltd operates and provides Isotop but is not the merchant of record.
• Payment details. We do not receive or store your full card details; payment is handled by Polar.
• Currency. Prices are in US Dollars (USD) unless stated otherwise at checkout.
• Taxes. Applicable taxes are calculated and collected by Polar at checkout; transactional surfaces indicate that taxes apply where relevant.
• Invoices and receipts. Invoices and receipts are provided by Polar (by email and/or the Polar customer portal). The Service does not itself generate invoices.
• Renewal. Paid subscriptions renew automatically for successive billing periods until cancelled.
• Cancellation. You can cancel your paid subscription through the Polar customer portal (reachable from the billing area of the Service).
• What happens when you cancel. After you cancel, your paid features and credits continue until the end of the paid period you have already paid for, and your account then automatically returns to the Free plan. We do not display an “ends on date” notice, and these Terms do not promise one.
• Failed payments. If a payment fails and the subscription becomes past due, paid features pause. Polar retries payment (dunning); when payment succeeds, access is automatically restored. Credits already granted for the current period remain. No grace period is promised.
• No free trial. There is no separate paid-plan free trial at launch; the Free plan is the way to try the Service before buying.
• Price changes. We may change prices. Changes apply from your next billing period, are announced by a site update, and are not charged retroactively.
• Chargebacks. Payment disputes and chargebacks are handled through Polar; any resulting effect on your account is reviewed on a case-by-case basis.

• Statutory rights. Where the law that applies to you gives you a right to a refund or to withdraw from a purchase, those rights apply and are not limited by this section. Stronger mandatory local law always prevails.
• Withdrawal / cooling-off (baseline). For eligible consumer purchases, we offer a 14-day withdrawal (“cooling-off”) period as a baseline, in addition to any stronger mandatory right you have under local law.
• Other refunds. Outside mandatory rights and the baseline above, refunds are handled case-by-case through support (support@isotop.app). Where a refund is granted, it is executed through Polar; a granted refund is then manually paired by us with the corresponding change to your subscription. A refund event by itself does not automatically revoke access — access changes are made through the ordinary cancellation/subscription process.
• Credits are not money. A credit “refund” (credits restored to your balance, for example after a failed operation) is not a monetary refund and has no cash value (see §8).

Collider AI usage is metered in credits.

• What credits are. Credits are a metered usage allowance for AI features. They have no cash value, are not money or a stored-value instrument, and are non-transferable, non-giftable, not separately purchasable, and not convertible.
• How usage is metered. Approximately 1 credit per 1,000 AI tokens used (combined input and output, rounded up); high-effort generations are metered at 1.5×. These rates are shown in the product.
• Allowances and reset. Each plan includes a credit allowance. The Free plan includes a small monthly allowance that resets on a UTC calendar-month basis; a paid plan’s allowance resets each billing period. Credits do not roll over — each refill resets your balance to your plan’s allowance; unused credits do not carry over past your next refill.
• Downgrade. If you move to a lower plan, you do not immediately lose your current balance; it persists until the next grant boundary resets it to the new plan’s allowance.
• Cancellation. Credits keep granting and can be spent through the end of the paid period after you cancel.
• Failed operations. If an AI generation fails, it is generally not charged — the reserved credits are restored automatically. In rare technical cases a reservation may remain charged; if that happens, contact support and we will correct it using our per-operation usage records.

• AI is assistive; you review outputs. Collider generates suggestions and content using third-party AI providers. AI output can be inaccurate, incomplete, or unsuitable, and is not professional advice. You are responsible for reviewing AI-generated output before you rely on or use it, and for how you use it.
• Acceptable use of AI. You must not use Collider or any AI feature for unlawful, abusive, infringing, deceptive, or security-compromising activity, or to attempt to generate such content (see also the general acceptable-use rules in §10).
• Confidential and sensitive content. You may use the Service with confidential or client-owned design content where you are authorized to process it (see §4). You must not submit credentials or secrets, highly sensitive personal data, or regulated or special-category data unless the Service expressly supports that use.
• How your content is used. Content you submit to AI features is processed to provide those features. We do not claim any right to use your private Content for marketing without your separate permission. Our AI provider processes submitted content under its own terms; details of AI processing, providers, and retention are in the Privacy Policy.

You agree not to, and not to attempt to, and not to allow anyone else to:

• use the Service in violation of any applicable law or regulation, or to infringe anyone’s intellectual-property, privacy, or other rights;
• upload or process content you do not have the rights or authority to submit (see §4);
• upload malware or use the Service to compromise, probe, or interfere with the security or integrity of the Service, its infrastructure, or other users;
• attempt to gain unauthorized access to any account, system, or data;
• reverse engineer, decompile, or disassemble the Service except to the extent this restriction is prohibited by applicable law;
• scrape, harvest, or bulk-extract data from the Service other than your own data through provided features;
• circumvent, disable, or interfere with usage limits, rate limits, metering, billing, or access controls;
• resell, sublicense, or commercially exploit the Service except as expressly permitted;
• use the Service to build a competing product by copying it;
• use the Service for any abusive, deceptive, harassing, or otherwise harmful activity.

We may investigate suspected violations and take proportionate action, including warning, suspending, or terminating access (see §14).

• Your Content stays yours. As between you and us, you retain all rights you have in your Content. These Terms do not transfer ownership of your Content to us.
• License you grant us. You grant Island AI Ltd a limited, non-exclusive, worldwide, royalty-free license to host, store, copy, transmit, display, and process your Content solely to operate and provide the Service to you (including transmitting it to the third-party providers that power features you use, such as the AI provider and infrastructure providers). This license exists only to run the Service for you and ends when your Content is deleted from the Service, subject to retained copies and backups described in the Privacy Policy. We do not use your private Content for advertising or to market to others, and do not sell or “share” it for cross-context advertising.
• Your responsibility for Content. You represent that you have the necessary rights and authority for your Content and its processing as described here (see §4), and that your Content and its use do not violate law or these Terms.
• Our intellectual property. The Service — including its software, design, text, graphics, and the “Isotop” name and logos — is owned by Island AI Ltd or its licensors and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose while these Terms are in effect. All rights not expressly granted are reserved.
• AI output. Rights in AI-generated output are subject to the terms of the AI provider that generated it and to applicable law; you are responsible for your use of that output (see §9).
• Feedback. If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them without obligation to you.

The Service relies on third-party providers to function, including Polar (payments / merchant of record), our AI provider (Collider generation), Google Firebase / Google Cloud (authentication, database, storage, hosting), Resend (transactional email), and Google reCAPTCHA / Firebase App Check (abuse prevention); a Google Fonts request is used to preview design-system fonts. Their processing of personal data is described in the Privacy Policy and Cookie Policy. Your use of some features may also be subject to the third party’s own terms (for example, Figma and Polar). We are not responsible for third-party services we do not control, except as required by law.

Your use of the Service is also governed by the Privacy Policy and Cookie Policy, which explain what personal data we process, why, the third-party processors involved, retention, and your rights (including access/export and deletion). Please read them.

• By you. You may stop using the Service at any time and may delete your account (see §4).
• By us. We may suspend or terminate your access, in whole or in part, if you breach these Terms, if required by law, or to protect the Service, other users, or third parties from harm or security risk. Where reasonable and lawful, we will give notice; for serious issues (for example, security or unlawful use) we may act immediately.
• Effect of termination. On termination, your license to use the Service ends and paid features stop, subject to §6 (access through a paid period you have already paid for) and to any mandatory refund/withdrawal rights (§7). Provisions that by their nature should survive — including content ownership, IP, disclaimers, limitation of liability, and the governing-law/dispute provisions — survive termination. Handling of your data after termination is described in the Privacy Policy.

To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that AI output will be accurate, complete, or fit for your purpose. Nothing in these Terms excludes or limits any warranty or right that cannot be excluded or limited under the law that applies to you (including mandatory consumer rights).

To the maximum extent permitted by applicable law, and except for liability that cannot lawfully be limited: we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, data, or goodwill. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

To the extent permitted by applicable law, if you use the Service for business or professional purposes, you agree to indemnify and hold Island AI Ltd harmless from third-party claims arising out of your Content, your use of the Service in violation of these Terms or law, or your breach of the authority/rights representations in §4 and §11.

These Terms do not currently designate a governing law or an exclusive forum. Nothing in this section limits any mandatory consumer-protection or data-protection rights you have, or your right to bring claims, under the law that applies to you.

See §2 (“Changes to these Terms”). Each version has its own version identifier and effective date; material changes are notified; re-acceptance is requested where required by law or where a material change makes it appropriate.

• Entire agreement. These Terms, with the Privacy Policy and Cookie Policy, are the entire agreement between you and us regarding the Service and supersede prior agreements on that subject.
• Severability. If any provision is held unenforceable, the rest remains in effect and the unenforceable provision is limited to the minimum extent necessary.
• No waiver. Our failure to enforce a provision is not a waiver of it.
• Assignment. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, reorganization, or sale of assets, subject to applicable law.
• Force majeure. We are not liable for delay or failure caused by events beyond our reasonable control.
• No agency. Nothing here creates a partnership, agency, or employment relationship between you and us.
• Contact. Questions about these Terms: support@isotop.app, Island AI Ltd, Office A, Innovation City Business Centre, RAK BANK ROC Office, Ground Floor, Al Riffa, Sheikh Mohammed Bin Zayed Road, Ras Al Khaimah, United Arab Emirates.
