Terms of Service
Last updated: May 12, 2026. Please read these terms carefully before utilizing the MarklyKit platform and services.
Agreement to Terms
These Terms of Service constitute a legally binding agreement made between you, whether personally or on behalf of an entity, and MarklyKit concerning your access to and use of the website as well as any other media form, media channel, mobile website or mobile application related, linked, or otherwise connected thereto.
You agree that by accessing the Site, you have read, understood, and agree to be bound by all of these Terms of Service. If you do not agree, you are expressly prohibited from using the Site and you must discontinue use immediately.
License to Use
Limited License Grant
We grant you a non-exclusive, non-transferable, revocable license to access and use the platform strictly in accordance with these terms of service and any applicable subscription plans.
AI Connectors
MarklyKit Pro lets you connect third-party AI assistants (currently Claude.ai, ChatGPT, and Grok) to your research via our hosted Model Context Protocol (MCP) server. Your use of these connectors is governed by the following terms:
- Authorization is yours. You initiate each connection in the third-party AI client and authorize it via OAuth. MarklyKit never shares your research with an AI provider without your explicit, per-connector consent.
- Third-party terms apply.Once an authorized AI client retrieves your research, that provider's terms of service and privacy policy govern how the content is processed. MarklyKit is not responsible for the actions of third-party AI providers.
- Acceptable use. You agree not to use AI connectors to process content you do not have the right to use, to generate unlawful, infringing, or harmful material, or to attempt to circumvent rate limits, scopes, or security controls.
- Service availability.MCP and connector functionality are provided on an “as-is” basis. We may rate-limit, suspend, or modify connector behavior to protect service stability or comply with the requirements of upstream AI providers.
- Revocation.You can revoke any connector at any time from Settings → API Keys. Revocation takes effect immediately for new requests.
Billing & Refunds
MarklyKit uses Dodo Payments as our primary payment merchant. By subscribing to a Pro Plan, you agree to their terms of service in addition to ours. All payments are processed securely.
14-Day Refund Guarantee
We offer a no-questions-asked 14-day money-back guarantee for all new subscriptions. If you are not satisfied with MarklyKit Pro, contact us within 14 days of your initial purchase for a full refund.
Limitation of Liability
In no event will we or our directors, employees, or agents be liable to you or any third party for any direct, indirect, consequential, exemplary, incidental, special, or punitive damages, including lost profit, lost revenue, loss of data, or other damages arising from your use of the site, even if we have been advised of the possibility of such damages.
Account Termination
You may delete your account at any time from Dashboard → Account → Danger zone. If you have an active Pro subscription, you must cancel it before deleting — this protects you from being billed against a card you can no longer reach.
Cancelling a Pro subscription does not delete your account. Pro features remain active until the end of the current billing period, after which the account reverts to the free tier and no further charges occur. You can keep using MarklyKit on the free tier or delete the account whenever you want.
We do not store copies of your data after deletion. When you delete your account, all highlights, notes, sticky notes, folders, tags, API keys, and OAuth grants are permanently and irreversibly removed within 24 hours. We retain only the minimal billing records required by tax and accounting law (invoice number, amount, and date — no content), anonymised from your identity and held for the period required by applicable regulation. Account deletion cannot be undone.
We may suspend or terminate accounts that breach these Terms, abuse the Service, or that we are required by law to remove. Where reasonably possible we will give you notice and an opportunity to export your data first.
