Terms of Service

By using the Service you agree to these Terms and to our Privacy Policy, which is incorporated by reference. If you do not agree, you must not use the Service.

• Workspace — the multi-tenant container (referred to in our systems as an "account") that holds your webinars, attendees, automations, integrations, and billing relationship. One person may create or join multiple Workspaces.
• Owner — the member of a Workspace with full administrative and billing rights. Each Workspace has at least one Owner.
• Member — a user invited to a Workspace with a non-Owner role. Roles determine which features a Member can access; Members do not have billing rights.
• Attendee — an end user who registers for or views a webinar hosted on the Service by a Workspace.
• Customer Content — webinars, recordings (hosted on third-party services and embedded), registration forms, automations, email copy, custom domains, attendee lists, and any other data you upload, configure, or generate within a Workspace.
• Subscription — the paid plan associated with a Workspace, billed through our payment processor on a monthly or yearly cadence.

You must be at least 18 years old and legally capable of forming a binding contract to use the Service. You agree to provide accurate, current, and complete information when creating an account and to keep it current. You are responsible for safeguarding your credentials and for all activity that occurs under your account. Notify us immediately at legal@webinarstack.co if you suspect unauthorized access.

We use Supabase Auth to authenticate users. Email verification is required before a Workspace can be created or joined.

Each Workspace is its own tenant: data, billing, members, integrations, and capability entitlements are scoped to the Workspace. A single user may belong to multiple Workspaces with different roles in each.

The Owner of a Workspace is responsible for: (a) the Subscription and all charges incurred under it; (b) compliance with these Terms by every Member of the Workspace; (c) ensuring that Members are authorized to access Customer Content and Attendee data; and (d) revoking Member access when no longer needed.

Seat limits per plan are enforced. Inviting Members beyond your plan's seat limit is not permitted; upgrade to a higher tier or to Scale (with a custom seat override) if you need additional seats.

WebinarStack is a SaaS platform that lets Customers publish pre-recorded webinars that feel live, track detailed attendee behavior (registration, watch-time, interactions, poll responses, offer clicks, chat), and trigger automations (emails, webhooks, Slack messages, third-party integrations) based on that behavior.

Video playback is delivered via embedded third-party providers (YouTube, Vimeo) selected by the Customer. Transactional email is delivered via our email service provider. WebinarStack does not host, transcode, or store raw video files.

You may cancel your Subscription at any time from the Billing settings in your Workspace. Cancellation takes effect at the end of the current billing period; you retain access to paid features until that date. Cancellation does not entitle you to a refund for any portion of fees already paid.

We may suspend or terminate your account or a specific Workspace at any time, with or without notice, if: (a) you materially breach these Terms; (b) we are required to do so by law; (c) your use creates a security, legal, or fraud risk to us, our other customers, or any third party; or (d) you fail to pay fees when due after the cure period described in Section 6.

All fees are non-refundable except where required by law. We do not refund partial billing periods, unused attendee allowance, or unused seats. Annual plans are not refundable upon cancellation or downgrade. If you believe you have been billed in error, contact legal@webinarstack.co within 30 days of the charge.

You agree not to use the Service to:

• Violate any law, regulation, or third-party right (including intellectual property, privacy, and publicity rights).
• Distribute content that is illegal, defamatory, fraudulent, harassing, obscene, or that promotes violence or discrimination.
• Send unsolicited or unlawful commercial messages, or otherwise violate CAN-SPAM, CASL, GDPR, or other applicable anti-spam or marketing laws when using our automation, email, or webhook features.
• Upload or transmit malware, attempt to probe, scan, or test the vulnerability of the Service, or bypass any security or rate-limiting mechanism.
• Reverse engineer, decompile, or attempt to extract the source code of the Service, except to the extent expressly permitted by law.
• Resell, white-label, or sublicense the Service to third parties without a written agreement with us.
• Use the Service to operate a competing product, scrape data at volume, or train machine learning models on Customer Content or attendee behavior data that is not yours.
• Misrepresent a pre-recorded webinar in a manner that violates applicable consumer protection or advertising laws in the jurisdictions where your attendees are located.

We may investigate suspected violations and take any action we deem appropriate, including removing content, suspending automations, or terminating accounts.

You retain all rights in your Customer Content. We do not claim ownership of your webinars, registration data, attendee data, automations, or any other content you create within a Workspace.

You grant WebinarStack a worldwide, non-exclusive, royalty-free license to host, store, transmit, display, copy, and process your Customer Content solely as needed to provide and improve the Service, deliver attendee experiences, run automations you have configured, and meet our legal obligations. This license ends when the Customer Content is deleted, except where retention is required by law or legitimate business records.

You represent and warrant that you have all rights necessary to upload your Customer Content and to grant the license above, and that your Customer Content does not violate any third-party right or applicable law.

With respect to personal data of Attendees collected through the Service, you are the data controller (or equivalent) and WebinarStack is the data processor acting on your documented instructions. You are responsible for: (a) providing legally adequate notice to Attendees, including your own privacy policy on the registration form; (b) obtaining any required consents; (c) responding to data subject requests directed at you as controller; and (d) complying with applicable privacy laws (including GDPR, CCPA/CPRA, and the Colorado Privacy Act) in the jurisdictions where your Attendees are located.

A Data Processing Addendum (DPA) is available on request to legal@webinarstack.co. Our processing practices, sub-processors, and the categories of data we collect are described in our Privacy Policy.

The Service relies on and integrates with third-party services, including video hosts (YouTube, Vimeo), payment processing (Stripe), authentication and database infrastructure (Supabase, Neon), background job orchestration (Inngest), transactional email (Postmark/SendGrid), application hosting (Vercel), caching (Upstash), and optional Customer-configured integrations (Slack, ConvertKit, ActiveCampaign, Mailchimp, MailerLite, and others). Your use of those services is subject to their own terms.

We are not responsible for the availability, performance, content, or actions of any third-party service. Outages or changes to third-party APIs may affect features of the Service; we will make reasonable efforts to maintain compatibility but make no guarantees.

WebinarStack and its licensors retain all right, title, and interest in and to the Service, including all software, technology, designs, trademarks, logos, documentation, and improvements, derivative works, and feedback. No rights are granted to you except as expressly set out in these Terms.

If you submit ideas, suggestions, or feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use that feedback for any purpose without obligation to you.

Each party may receive non-public information from the other in connection with the Service. The receiving party will protect such information using at least the same degree of care it uses for its own confidential information (and no less than reasonable care), and will use it only to perform under these Terms. This obligation does not apply to information that is publicly available, independently developed, or required to be disclosed by law (with prompt notice to the other party where legally permitted).

We implement industry-standard security measures including TLS encryption in transit, Row Level Security enforcing tenant isolation at the database layer, encrypted storage of API credentials, secure authentication via Supabase, and audit logging. No system is 100% secure, and we do not guarantee that the Service will be free from unauthorized access, interception, or loss. You are responsible for the security of your own credentials and devices.

We strive to keep the Service available and performant but do not commit to a specific uptime SLA on Starter, Growth, or Pro plans. Scale plans may include negotiated service level commitments documented in a separate written agreement.

We may add, modify, deprecate, or remove features at our discretion. For material removals of features that you actively use, we will provide reasonable advance notice (typically at least 30 days) via in-product notice or email.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT ANY DEFECT WILL BE CORRECTED. NO ADVICE OR INFORMATION OBTAINED FROM US CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WEBINARSTACK BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, USE, OR BUSINESS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL CUMULATIVE LIABILITY UNDER THESE TERMS WILL NOT EXCEED THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. THESE LIMITATIONS APPLY TO ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE, AND SURVIVE TERMINATION OF THESE TERMS.

You will defend, indemnify, and hold harmless WebinarStack, its affiliates, and their respective officers, directors, employees, and agents from and against any claim, demand, loss, liability, damage, or expense (including reasonable attorneys' fees) arising out of or related to: (a) your Customer Content; (b) your use of the Service in violation of these Terms or applicable law; (c) your violation of any third-party right; or (d) any dispute between you and an Attendee or Member.

We may update these Terms from time to time. For material changes (including price changes, changes to dispute resolution, or changes that reduce your rights), we will provide at least 30 days' notice by posting the updated Terms on this page, updating the Effective Date, and sending an email to the address on file. Non-material changes take effect on posting. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

• Entire Agreement. These Terms, together with the Privacy Policy and any written order form or DPA referenced here, constitute the entire agreement between you and WebinarStack regarding the Service.
• Severability. If any provision is held unenforceable, the remaining provisions will remain in full force and effect.
• No Waiver. Our failure to enforce any right or provision is not a waiver of that right or provision.
• Assignment. You may not assign these Terms or any rights or obligations under them without our prior written consent, except to a successor in connection with a merger or sale of substantially all assets. We may assign these Terms freely.
• Force Majeure. Neither party will be liable for any failure or delay caused by events beyond its reasonable control, including acts of God, war, terrorism, labor disputes, government action, or failure of telecommunications or hosting providers.
• Notices. We may give notice to you by email, in-product notification, or by posting on the Service. You agree that electronic notice satisfies any legal requirement that such communications be in writing.
• Independent Contractors. No agency, partnership, joint venture, or employment relationship is created by these Terms.
