Terms of Service

You must be at least 18 years old and capable of forming a binding contract to use the Services. By using the Services, you represent and warrant that you meet these requirements. If you are using the Services on behalf of a company or organization, you represent that you have authority to bind that entity to these Terms.

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at hello@siden.ai if you suspect unauthorized access.

You may not share your account credentials with others. Each seat on a team plan is licensed to one individual user. You may invite additional team members within the limits of your plan.

You agree not to use the Services to:

• Violate any applicable law or regulation
• Upload documents you do not have the right to share or process
• Attempt to reverse-engineer, scrape, or extract the underlying AI models
• Circumvent usage limits, billing controls, or authentication mechanisms
• Upload malicious content, malware, or exploits
• Use the Services to build a competing product without prior written consent
• Harass, defraud, or harm other users or third parties

We reserve the right to suspend or terminate accounts that violate these rules without prior notice.

Access to certain features requires a paid subscription. Current plan pricing and limits are described on our Pricing page.

Billing cycle. Subscriptions are billed monthly or annually in advance. Payments are processed by Stripe.

Cancellation. You may cancel your subscription at any time through the in-app subscription management portal. Cancellation takes effect at the end of the current billing period. We do not provide prorated refunds for mid-cycle cancellations.

Price changes. We may change subscription prices with at least 30 days’ notice. Continued use after the notice period constitutes acceptance of the new pricing.

Team seats. Small Firm and Firm Pro plans are priced per seat. The seat count billed is set at the time of purchase and may be adjusted at renewal.

You retain all ownership rights to the documents and data you upload to the Services (“Your Content”). By uploading Your Content, you grant Siden a limited, non-exclusive license to process it solely for the purpose of providing the Services to you.

You are solely responsible for ensuring that Your Content does not violate any applicable law, third-party rights, or confidentiality obligations. We do not review uploaded documents for legality or compliance.

Sidera uses artificial intelligence to analyze documents and generate answers. You acknowledge that:

• AI outputs are for informational purposes only and do not constitute legal advice
• You should verify AI-generated answers against the cited source material before relying on them
• Siden makes no warranty regarding the accuracy, completeness, or fitness of AI outputs for any particular purpose

Nothing in the Services creates an attorney-client relationship between you and Siden.

The Services, including all software, design, trademarks, and content created by Siden, are owned by Siden Technologies Inc. and protected by applicable intellectual property laws. You may not copy, modify, distribute, or create derivative works from our intellectual property without prior written consent.

We treat your uploaded documents and query content as confidential. We will not disclose your document content to third parties except as required to deliver the Services or as described in our Privacy Policy.

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SIDEN SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY. IN NO EVENT SHALL SIDEN’S AGGREGATE LIABILITY TO YOU EXCEED THE TOTAL FEES PAID BY YOU TO SIDEN IN THE 12 MONTHS PRECEDING THE CLAIM.

You agree to indemnify and hold harmless Siden, its officers, directors, employees, and agents from and against any claims, liabilities, damages, and expenses (including reasonable attorneys’ fees) arising out of or related to your use of the Services, Your Content, or your violation of these Terms.

We may suspend or terminate your access to the Services at any time, with or without cause, with or without notice. You may terminate your account at any time by canceling your subscription and contacting us. Upon termination, your right to use the Services ceases immediately.

These Terms are governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of law principles. Any dispute arising under these Terms shall be resolved exclusively in the state or federal courts located in Delaware.

We may update these Terms at any time. We will notify you of material changes by email or by posting a notice in the Services. Continued use of the Services after the effective date of changes constitutes your acceptance of the updated Terms.
