Exomem Cloud terms

These terms are an agreement between you and Substrate Systems OÜ (Estonian registry code 17394552), Siidisaba tn 13/2-14, 11311 Tallinn, Estonia, for Exomem Cloud. They apply when you receive an invitation or use the Cloud service. The open-source Exomem software remains governed by the license in its repository.

Eligibility and availability

You can start Exomem Cloud with your email address. If admission is paused or Cloud is full, we add you to a waitlist. We email you when a place opens. Joining the waitlist does not create an account or promise a date.

You must be at least 18 years old and legally able to enter this agreement. Provide accurate account information, keep access to your email and connected clients secure, and promptly tell us about suspected unauthorized use. An account is personal and may not be sold or transferred.

The service

Exomem Cloud provides an isolated managed knowledge store through approved MCP clients. Client availability and model behavior are partly controlled by third-party providers such as Anthropic and OpenAI and remain subject to their terms. We may change features, limits, compatible clients, or infrastructure as the service develops. We do not promise a service-level agreement, but we will operate the service with reasonable care and communicate material changes where practicable.

Your data

You retain ownership of the knowledge content you provide. You grant Substrate Systems OÜ a limited, non-exclusive permission to host, copy, process, index, transmit to your authorized clients, secure, export, and delete that content only as needed to provide and protect Exomem Cloud. You are responsible for having the right to store and process the content you submit. The privacy policy explains the plaintext-in-cell boundary and how service providers handle data.

Acceptable use and availability

Do not use Exomem Cloud to break the law; infringe privacy, confidentiality, or intellectual property rights; distribute malware; harm or deceive others; probe another tenant; bypass quotas, access, or security controls; interfere with the service; or use automated traffic that creates unreasonable load. We may apply reasonable storage, request, and rate limits. We may suspend access immediately where needed to protect users, data, infrastructure, or third parties, and will give notice where lawful and practicable.

Subscription, export, and deletion

Exomem Cloud is a monthly subscription. Paddle sells it as our reseller and merchant of record, and handles payment, tax and invoices under its own buyer terms. A friend's invitation can include a lower price that lasts while you stay subscribed, and some invitations cover the subscription. If a payment fails, your Cloud stays available read-only while Paddle retries it.

You can stop using the service, disconnect clients, export your canonical data, and request verified account deletion at any time. Ending access does not erase information already sent to a third-party client; manage that information with the client provider.

If you cancel an Exomem Cloud subscription, your data remains available in a read-only state for 30 days after cancellation so you can export it. We will name the exact end date in the cancellation email. If you resubscribe before that date, access is restored; after it, your Cloud cell and its data are deleted.

Intellectual property and feedback

These terms do not transfer ownership of your content or the open-source rights granted by Exomem's repository license. Substrate Systems OÜ retains rights in the Cloud service, site, branding, and non-open-source materials. If you send feedback, you allow us to use it without obligation, but it does not give us rights to your knowledge content.

Warranty and liability

The service is provided on an as-available basis. To the extent permitted by law, we disclaim implied warranties and are not liable for indirect, incidental, special, or consequential loss. Our aggregate liability for the Cloud service is limited to the amount you paid for it in the twelve months before the event giving rise to the claim. Nothing in these terms excludes liability or consumer rights that applicable law does not allow us to exclude or limit.

Termination, law, and changes

You may terminate by cancelling your subscription or requesting deletion. We may end an account for material breach, security risk, legal requirement, or discontinuation of the service. If we discontinue the service we will give reasonable notice, refund any prepaid period not yet used, and keep export available through that notice period. Provisions that by their nature survive termination—including ownership, retained legal records, warranty, and liability terms—continue to apply. Estonian law governs these terms, without depriving consumers of mandatory protections available in their country. Disputes are subject to the competent Estonian courts unless mandatory consumer law provides otherwise.

We will update the revision date and provide appropriate notice before a material change takes effect. Questions or legal notices go to founder@substratesystems.io. See the privacy policy and support page for the related service details.
