Matters not covered here follow applicable Korean law, including consumer, privacy, content, contract, and civil law.

• “Member” means a person who creates an account and uses the Service.
• “Workspace” means an independent unit for knowledge sources, AI settings, conversations, and team permissions.
• “Administrator” means a member authorized to manage workspace members, billing, knowledge, and service settings.
• “Customer” means an end user who communicates through a member’s widget.
• “Knowledge source” means a registered website, file, Q&A, or other content used to generate answers.
• “AI conversation” means a conversation in which generative AI answers a customer, or the usage unit defined by a plan.

The Company publishes these Terms where members can readily review them. Amendments are normally announced at least seven days before they take effect; adverse or material amendments are announced at least 30 days beforehand by email or in the Service.

Where separate consent is legally required, the Company obtains it. A member who does not agree may cancel a subscription or stop using the Service before the effective date.

Members must provide accurate, current information and secure their login links, accounts, and workspace permissions. Registration may be delayed or refused for technical problems, false information, previous abuse, or legal restrictions.

Administrators are responsible for invitations, sources, notification recipients, allowed widget domains, and billing settings. Authorized administrator actions may be treated as valid workspace instructions.

Deyo searches knowledge registered by a member to answer customer questions. When evidence is insufficient or an actual account check is required, it can route the conversation to Deyo Inbox and configured Slack or email notifications. Features, models, usage, storage, and support can vary by plan.

Deleting a normal knowledge source removes it from answer retrieval immediately and permits restoration in the Service for seven days. Restoring an FAQ file also restores its connected Q&A. After seven days, source text, retrieval data, and related records may be permanently deleted. Material explicitly deleted during onboarding is permanently deleted immediately.

Stopping an import clears unpublished versions and temporary extraction data; a previously published version remains available during a replacement import. Multiple files are processed in the workspace background queue.

Generative answers are probabilistic. The Company does not guarantee completeness, accuracy, recency, or fitness for a specific purpose. Members must test representative questions before launch and provide human review for legal, medical, tax, financial, account, billing, and other professional or real-time matters.

Each new workspace receives one limited seven-day trial without a card. It does not become a paid subscription unless a payment method is registered. Trial knowledge limits are 5 MB of processed text, 10 logical sources, and 150 web pages per import.

Adding a Starter or Pro payment method during the trial does not restart the trial. The chosen plan’s full trial limits apply until the existing end date, when the first payment is attempted. If trial eligibility has expired, the displayed first fee is charged after card authentication. Canceling scheduled billing before trial end switches the workspace to Free without a charge.

Default knowledge limits are: Free 1 MB, 3 sources, and 50 pages per web import; Starter 10 MB, 100 sources, and 150 pages; Pro 40 MB, 300 sources, and 300 pages. Capacity is based on normalized UTF-8 text, logical source count, and selected web pages—not only upload bytes.

Monthly plans are prepaid monthly. Annual plans prepay one year at a 20% discount from twelve monthly payments. Consumer prices are displayed in Korean won including VAT. Toss Payments processes card number and CVC; the Company does not store them directly. The billing key required for recurring payment is encrypted.

Plan and billing-cycle changes normally take effect at the next renewal and are not prorated unless shown otherwise. Trial cancellation uses the Service through the trial end and then moves to Free without charge. Paid cancellation uses the Service through the current paid period and then moves to Free.

Cancellation can be requested and withdrawn before its effective date in Settings > Billing. If the Service screen is unavailable, email the workspace and request details to ceo@stephow.me. Account deletion and subscription cancellation are separate requests.

If knowledge exceeds Free limits at trial end, the member can choose what to retain. Deyo does not keep an arbitrary subset; knowledge use is paused, and excess knowledge is retained inactive for 30 days. Selecting within the limit or subscribing restores it without recollection. Excess data may be deleted after that period.

Statutory rights under applicable consumer and e-commerce law prevail. Where a withdrawal period applies, members can contact ceo@stephow.me with the order, workspace, payment date, and request.

Withdrawal may be limited after digital service performance begins only when all legally required notice and consent conditions are satisfied. The Company does not categorically exclude statutory rights.

There is no automatic prorated refund for a simple change of mind after use. Duplicate or erroneous charges, a material outage attributable to the Company, statutory withdrawal, or another legally required reason may qualify for a full or partial refund after review, normally to the original payment method.

For a previously paid renewal, Deyo may retry up to three times at the initial failure, one day later, and three days later. Paid access may remain for seven days from the first failure, after which the workspace moves to Free if payment is not recovered. This grace period does not apply when the first payment after a trial fails.

The Company may notify members of failures, retries, payment-method changes, and access changes. Suspected fraudulent or unauthorized payment can be restricted.

Members must hold the rights and lawful authority required for uploaded or connected content and must not violate confidentiality, privacy, copyright, trademark, or third-party rights.

Members grant the Company a non-exclusive permission to store, copy, transform, search, and transmit content only as needed to provide, secure, and recover the Service or perform requested features. The Company does not claim ownership of member content.

A member operating a widget is responsible for lawful notices and, where required, consent concerning customer-data purposes, fields, retention, vendors, and international processing. The Company processes customer data within the member’s instructions and Service scope.

• Unauthorized access, bypassing controls, exploiting vulnerabilities, attacking the Service, or malicious automation.
• Illegal or harmful content, fraud, spam, discrimination, defamation, or infringement.
• Bypassing security, cost, or usage limits, or improperly reverse-engineering, copying, or reselling the Service.
• Registering customer data, confidential information, or copyrighted material without required authority and notice.
• Misrepresenting AI as a person or as a replacement for professional judgment.

The Company may restrict, suspend, or terminate content or accounts where reasonably necessary for law, security, non-payment, repeated breach, or urgent operational risk. Non-urgent cases receive a reason and reasonable opportunity to remedy where appropriate.

The Service may use Supabase, Vercel, OpenAI, Google, Resend, Toss Payments, Slack, and other providers. Their outages, policies, and separate terms fall within their responsibility, while the Company applies reasonable vendor management and recovery efforts.

Each party must use the other party’s non-public technical, commercial, and customer information only for the Service and not disclose it without authority, except for public, lawfully held, or legally compelled information.

The Service may be interrupted for maintenance, incidents, security events, network or cloud failures, force majeure, or legal orders. Planned interruptions are announced where practicable; emergencies may be explained afterward.

Members may review, export, or request deletion of data within available features. Free and trial workspaces are deactivated immediately on deletion; a paid workspace with time remaining is deactivated at period end. Customer content, including conversations, knowledge, and attachments, is permanently deleted 30 days after deactivation.

Minimum billing, contract, or security records legally required for disputes or retention are detached from the workspace and separately controlled for only the required period. Other data follows the Privacy Policy and backup rotation.

Deyo software, marks, design, documentation, and Company-created content belong to the Company or lawful rightsholders. Members receive a limited, non-exclusive, non-transferable right to use the Service during the agreement.

The Company may use feedback to improve the Service without charge where it contains no confidential information or personal data.

The Company uses reasonable technical and administrative care but does not guarantee error-free AI answers, uninterrupted availability, compatibility with every external service, or a specific business result.

Except for intent or gross negligence, and to the extent permitted by law, the Company is not liable for indirect, special, or consequential loss arising from free or beta functions, member content, third-party services, communications failures, force majeure, or AI output. Liability related to paid service is limited to fees actually paid for the affected workspace during the three months preceding the loss.

These limitations do not apply where they cannot legally limit intent, gross negligence, life or bodily injury, privacy obligations, statutory consumer rights, or other mandatory liability.

Notices may be provided by email, in-Service messages, or another reasonable electronic method. Members must keep contact information current.

Concerns and claims can be sent to ceo@stephow.me. The parties first seek a good-faith resolution. Korean law governs unresolved matters, and court jurisdiction follows applicable procedural law. Consumers may use applicable dispute-resolution bodies.

Consent remains effective from the July 17, 2026 version. The July 19, 2026 clarification aligns the explanation of customer-content deletion and legally retained records with actual deletion behavior.
