By downloading or using Synapsis, you agree to these terms. If you don't agree, please don't use the app.
You must be at least 13 years old to use Synapsis. Synapsis is not directed at children.
Synapsis is a macOS app that gives you an AI assistant you can talk to by text or voice, including answering questions about what's on your screen and searching the web for current information. Synapsis requires macOS 14 or later.
You can use Synapsis as a guest or sign in with your Google or Apple account. You're responsible for activity under your account and for keeping your Google or Apple account secure. You can delete your Synapsis account at any time from inside the app.
Guests get a daily usage allowance. Signing in for a free account doubles it. Pro and Max are paid monthly subscriptions with larger daily allowances, and require signing in. Prices are shown on our website and in the app at the time of purchase.
Subscriptions renew automatically each month until cancelled. You can cancel or update your payment details at any time through "Manage subscription" in the app. After you cancel, your plan stays active until the end of the period you've paid for, then returns to the free plan. If you switch between Pro and Max, your billing is adjusted automatically.
Payments are processed by Lemon Squeezy, acting as merchant of record, and its terms also apply to your purchase. If you think you were charged by mistake, contact us.
Daily allowances on every plan are subject to fair-use limits to prevent abuse, and may change over time. Promotional allowances, such as extra usage for early users, are temporary. We don't market any plan as unlimited.
You agree not to use Synapsis to:
We may suspend or close accounts that break these terms.
Your conversations and files remain yours. As described in our Privacy Policy, your chat history and memory are stored on your Mac, not on our servers, and conversations as a guest aren't saved. Content you send to get a response (such as a message, a screenshot, a file, or voice audio) is processed by third-party AI providers as needed to produce that response.
If you choose to share a conversation with us through feedback, you allow us to use it to improve Synapsis, as described in the Privacy Policy.
Synapsis uses AI models to generate responses, including by searching the web for current information. While we work to make responses accurate and helpful, AI-generated content can be wrong or incomplete, and web results may be outdated or inaccurate. Please check anything important before relying on it, especially for financial, medical, legal, or safety-related decisions.
Synapsis is provided "as is," without warranties of any kind, express or implied. We don't guarantee that the app will be uninterrupted, error-free, or that it will meet your specific needs.
To the fullest extent permitted by law, Synapsis and its operator are not liable for any indirect, incidental, or consequential damages arising from your use of the app, including damages resulting from reliance on AI-generated content or from service interruptions.
We may update, change, or discontinue features of Synapsis at any time. We'll make reasonable efforts to tell you about significant changes.
If we update these terms in a way that matters, we'll update this page and the date at the top. Continued use of Synapsis after a change means you accept the update.
These terms are governed by the laws of the Province of Ontario and the federal laws of Canada that apply there.
