Signyl.gg Terms of Use

Effective date: November 9, 2026
Last updated: November 9, 2026

1. Agreement

These Terms of Use ("Terms") are a binding agreement between you and Vitruvius Capital LLC, a California limited liability company doing business as Signyl ("Signyl," "we," "us"). They govern your use of Signyl.gg, including app.signyl.gg, your workspace at {name}.signyl.gg, the Signyl assistant, and any connected tools or interfaces such as MCP (together, the "Service").

By creating an account or using the Service you agree to these Terms and to the Signyl.gg Privacy Policy (https://signyl.gg/privacy). If you use the Service for a company, studio or other organization, you confirm you may bind it, and "you" includes it.

You must be 18 or older and using the Service for business or professional purposes.

2. Your account and workspace

Give accurate information, keep your sign-in secure, and tell us promptly at security@signyl.gg if you think your account is compromised. You are responsible for activity in your workspace, including by team members you invite. Workspace owners control who joins and what each member can do.

3. What Signyl does

Signyl helps you understand your product and audience, plan campaigns, make marketing pieces (copy, images, video and more), and publish approved pieces to channels you connect, then shows you how they did.

You stay in control. Signyl proposes; you confirm. Signyl publishes only pieces you approved, to the accounts you chose, at the times you set. Actions that cost money show their cost and ask before they run, unless you turn that question off for yourself.

AI output. Research, plans, copy, images and video are produced with AI models. They can be wrong, incomplete or similar to other material. Review everything before you approve it. Signyl does not give legal, financial or regulatory advice.

We may change, add or remove features. If we remove a feature you paid for, Section 9 explains what happens.

4. Your content and outputs

Your content. Everything you give Signyl (product details, brand assets, files, conversations) remains yours. You grant Signyl a worldwide, non-exclusive, royalty-free license to host, process, display and transmit it only as needed to provide the Service to you, including sending it to our service providers for the tasks you ask for. The license ends when you delete the content or your workspace, except for copies kept by law and backups deleted on their normal cycle.

Outputs. As between you and Signyl, you own the pieces Signyl makes for you ("Outputs"), and we assign to you any rights we have in them. Outputs may not be protectable by copyright, may resemble material made for others, and are subject to the terms of the model that made them.

No training. We do not use your content or Outputs to train AI models, and we contract with providers not to.

Aggregates. You agree Signyl may create and use de-identified, aggregated data about how kinds of pieces perform across workspaces, which identifies neither you, your content nor any person, to improve the Service.

Your responsibility. You confirm you have the rights to everything you give Signyl and to publish what you approve, including any trademarks, likenesses, music and third-party content in it.

5. Connected channels and publishing

You may connect accounts you control on X, Reddit, TikTok, YouTube, Facebook, Instagram, Discord, email and other platforms, through each platform's official sign-in. When you do:

  • you authorize Signyl to act for you on that platform within the permissions you granted, to post what you approve and read the results of those posts;
  • you are the publisher. What is posted is your content, posted as you. You are responsible for it complying with the platform's rules and with law, including advertising disclosure (for example FTC endorsement rules and TikTok's branded content labels), consumer protection, privacy and anti-spam laws;
  • you remain bound by each platform's own terms. Signyl is not affiliated with or endorsed by these platforms, and their trademarks belong to them;
  • platforms decide what they allow and can change, limit or end access at any time (for example, posting limits, visibility limits on new apps, or review requirements). Signyl is not responsible for a platform's decisions, outages or changes, or for what a platform does with content you post there;
  • some platforms charge for access. Where a platform charges for posting, Signyl shows the cost before you post;
  • you can disconnect a channel at any time; scheduled posts to it then stop.

Email and audiences. If you send email or messages through Signyl, you confirm the recipients agreed to hear from you, and you include any unsubscribe and sender information the law requires.

6. Fans and Signyl.me

People on Signyl.me control what you see about them. You may use what they share only inside Signyl to understand and engage your audience. You may not export it to build outside lists, sell it, share it, or combine it with other data to identify or profile people, unless that person separately agreed through a Signyl flow that says so. You may not try to re-identify anyone from aggregated insights.

7. Acceptable use

You agree not to:

  1. publish anything illegal, deceptive, defamatory, hateful, harassing, sexually explicit involving minors, or that infringes others' rights;
  2. impersonate anyone or misrepresent your affiliation, or post undisclosed paid endorsements;
  3. spam, run fake engagement, or use Signyl to manipulate platforms (inauthentic accounts, vote or follower schemes);
  4. connect accounts you don't control, or get around a platform's limits or reviews;
  5. scrape, harvest or resell data from Signyl or connected platforms;
  6. make content that falsely depicts real people, or deceptive synthetic media;
  7. probe, attack, reverse engineer or overload the Service, except under a written security research agreement with us;
  8. use the Service to build a competing product or to train AI models;
  9. break any law, including export, sanctions, privacy and anti-spam laws.

We may refuse to make or publish a piece that breaks these rules. Report security issues to security@signyl.gg; we will not pursue good-faith researchers who report promptly and do not access or keep others' data.

8. Our intellectual property

The Service, its software, design, the Signyl name and logos are owned by Vitruvius Capital LLC or our licensors. We grant you a limited, non-exclusive, non-transferable license to use the Service under these Terms. Feedback you send us may be used without obligation to you.

9. Fees, spending and payment

Prices for paid plans are shown before you buy. Paid plans are billed in advance and renew automatically until cancelled; you can cancel in the product, effective at the end of the current term. Metered actions (for example video generation) cost what is shown before they run, within the spending limits you set. We give at least 30 days' notice before a price increase. Fees are non-refundable except where the law requires or if we discontinue a paid feature, in which case we refund the unused prepaid portion. You are responsible for taxes other than on our income.

10. Confidentiality and data protection

Each party keeps the other's non-public business information confidential and uses it only for this agreement. Signyl handles personal information as described in the Privacy Policy. Where you give Signyl personal information about others, Signyl processes it as your service provider; a Data Processing Addendum is available on request at support@signyl.gg and applies where the law requires one.

11. Suspension and termination

You may stop using the Service and delete your workspace at any time. We may suspend or end your access if you seriously or repeatedly breach these Terms, if the law requires it, or if your use creates risk for Signyl, platforms or others; where reasonable, we tell you why first and give you a chance to fix it. We may end the Service with at least 30 days' notice and will give you a way to export your content and Outputs. Sections 4, 6, 8, 10, 12 and 13 survive.

12. Disclaimers, liability and indemnity

Disclaimer. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT THE LAW ALLOWS, SIGNYL DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT OUTPUTS WILL BE ACCURATE, ORIGINAL OR SUCCESSFUL, THAT ANY CAMPAIGN WILL REACH A RESULT, OR THAT CONNECTED PLATFORMS WILL CONTINUE TO ALLOW ACCESS.

Limitation of liability. TO THE FULLEST EXTENT THE LAW ALLOWS, NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR LOST PROFITS, REVENUE OR DATA. SIGNYL'S TOTAL LIABILITY FOR ALL CLAIMS IS LIMITED TO THE GREATER OF THE FEES YOU PAID IN THE 12 MONTHS BEFORE THE CLAIM AROSE OR US $100. These limits do not apply to fraud, gross negligence, willful misconduct, or your obligations under Sections 6, 7 and the indemnity below.

Indemnity. You will defend and indemnify Signyl against third-party claims arising from content you publish through the Service, your use of people's data, or your breach of Sections 5 to 7. We will notify you promptly and let you control the defense, subject to our reasonable approval of any settlement.

13. Disputes and governing law

California law governs these Terms, without regard to conflict-of-law rules. Before filing a claim, email legal@signyl.gg and we will try to resolve it within 60 days. Any dispute will be resolved in the state or federal courts in Los Angeles County, California, and each party consents to their jurisdiction.

14. General

We may update these Terms with at least 30 days' notice of material changes; continuing to use the Service after that date means you accept them. These Terms, the Privacy Policy and any order form or DPA are the entire agreement. If a part is unenforceable, the rest stands. Not enforcing a term is not a waiver. You may not assign these Terms without our consent; we may assign them in a merger, acquisition or sale of assets, with notice. Neither party is liable for delays beyond its reasonable control.
