Sage Terms of Service — Effective Date: April 2026 · Sage Green AI PBC Welcome to Sage — a personal thinking partner grounded in Stoic philosophy and the world's wisdom traditions, offered by Sage Green AI PBC, a Delaware Public Benefit Corporation. These Terms of Service govern your use of the Sage application and any related services. By using Sage, you agree to these terms. 1. What Sage Is (and Isn't) Sage is a philosophical guide, not a therapist, counselor, physician, or licensed mental health professional. Conversations with Sage are intended to support reflection, clarity, and the practice of living wisely. Sage is not a substitute for professional mental health care, medical advice, legal counsel, or crisis intervention. If you are experiencing a mental health emergency, please contact a qualified professional or crisis service immediately. Nothing in your conversations with Sage constitutes professional advice of any kind. 2. Eligibility You must be at least 13 years old to use Sage. If you are under 18, you represent that you have parental or guardian permission to use the Service. 3. Your Account and Encryption Password Certain features of Sage require you to create an account. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. Please notify us promptly at support@sagegreen.ai if you believe your account has been compromised. When you first use Sage, you will be asked to create an encryption password. This password is used to encrypt your memory before it is stored on our servers. We do not store this password and cannot recover it on your behalf. If you forget your encryption password, your Sage memory cannot be restored. Please choose a password you will remember and store it safely. 4. Acceptable Use You agree to use Sage in good faith and in a manner consistent with its purpose as a reflective, philosophical companion. You agree not to: attempt to manipulate or deceive Sage in ways intended to produce harmful outputs; use Sage to harass, harm, or gather information about any other person; reverse-engineer, scrape, or attempt to extract the underlying model or system prompts; use Sage for any unlawful purpose or in violation of any applicable law or regulation. We reserve the right to suspend or terminate accounts that violate these terms. 5. Subscriptions and Payments Sage offers a free trial period and a paid subscription. Paid subscriptions are billed on a monthly or annual basis, as selected at the time of purchase. All fees are non-refundable except as required by applicable law or as expressly stated at the point of purchase. We may change subscription pricing with reasonable advance notice. Your continued use of a paid subscription after a price change constitutes acceptance of the new pricing. If your subscription lapses, your encrypted memory is retained while you remain eligible to return. Contact support@sagegreen.ai for questions about your account. 6. Trees Planted Paid subscribers receive one tree planted per month of active subscription through our reforestation partners. Tree planting is carried out by third-party organizations; Sage Green AI PBC does not control or guarantee the outcome of any specific planting. 7. Intellectual Property The Sage application, including its design, system architecture, and branding, is the property of Sage Green AI PBC. Your conversation content remains yours. We do not claim ownership of what you share with Sage. 8. Disclaimers Sage is provided "as is" and "as available" without warranties of any kind, express or implied. 9. Limitation of Liability To the fullest extent permitted by law, Sage Green AI PBC shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of or inability to use the Service. 10. Indemnification You agree to indemnify, defend, and hold harmless Sage Green AI PBC and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys' fees, arising out of or in any way connected with your access to or use of the Service, your violation of these Terms, or your violation of any rights of another person or entity. Sage Green AI PBC reserves the right to assume exclusive defense and control of any matter subject to indemnification by you, in which case you agree to cooperate with our defense of such claims. 11. Changes to These Terms We may update these Terms from time to time. We will notify you of material changes through the application or by email. 12. Governing Law These Terms are governed by the laws of the State of Delaware, without regard to its conflict of law provisions. 13. Contact Questions about these Terms?

Sage Privacy Policy — Effective Date: September 2026 · Sage Green AI PBC Privacy is not a feature we added to Sage — it is a core commitment we make to you, and a design constraint we built the product around. 1. What We Collect Your Memory — Encrypted With a Key Derived From Your Password Sage builds a private, encrypted memory of what you share across sessions. This memory is encrypted in your browser using a password you create. The encrypted result is stored on our servers. We do not store your password. We do not hold your encryption key. We cannot read your stored memory. On our servers it exists only as ciphertext we have no key for, and we cannot produce its contents in response to a legal demand. What that does and does not mean. We want to be precise here, because the distinction is real and most products are vague about it. Sage is not "zero-knowledge," and we do not describe it that way. While you are in a live session, your browser sends your encryption key with each request so that Sage can read your memory and respond to you. During that request your content exists in unencrypted form in server memory, and is sent to the AI providers listed in Section 4. It is not written to disk in unencrypted form, and the key is discarded when the request ends. The accurate claim is that we cannot read your memory at rest — not that no one ever handles your content in plaintext. Each time you open Sage, you will be asked for your password to unlock your memory. If you forget it, your encrypted memory cannot be recovered. We recommend storing it somewhere safe — a password manager, or written down in a secure place. Session Data We store encrypted session transcripts to support continuity between your conversations. These are encrypted under the same key as your memory and subject to the same protections. Semantic Search Vectors So that Sage can find relevant memories from your past sessions, we generate semantic vectors — called embeddings — from your content. These are stored in our database unencrypted, so they can be searched quickly. Embeddings do not contain your literal words, but they do encode semantic information about the content they were generated from. Published research has shown that someone who obtained these vectors could reconstruct paraphrased approximations of the topics you discussed — not your exact words, but rough summaries of subject matter. We do not describe embeddings as anonymized, because they are not. This is a known limitation of how semantic memory retrieval works. We ship Sage this way because the alternatives — encrypted vector search, or generating embeddings on your device — would meaningfully delay the product or degrade what it can do. We continue to evaluate options for closing this gap. Account Information We collect your email address for authentication. Account sign-in uses magic links; we do not store a password for account access. The password described above is separate — it exists only to encrypt your memory, is never sent to us, and cannot be used to sign in. 2. What We Do Not Collect We do not sell your data. We do not share your conversation content with advertisers, data brokers, or third parties for commercial purposes. We do not build behavioral profiles for advertising. We do not train AI models on your personal data. Sage is built on Anthropic's API, which explicitly excludes API conversations from model training. 3. A Note on Legal Privilege AI conversations are not legally privileged in the way that communications with an attorney or licensed therapist are. We have responded to this reality with architecture: your memory is encrypted with a key we do not hold. We cannot produce the stored contents of your memory in response to a legal demand, because we do not have access to it. 4. Third-Party Services - Anthropic — AI model provider. Receives your conversation content to generate responses. API conversations are explicitly excluded from model training. - Voyage AI — semantic search provider. Receives your content to generate the embeddings described in Section 1. We have opted out of Voyage's use of customer content for model training. - Supabase — database and infrastructure. Stores your encrypted memory, encrypted transcripts, and unencrypted embeddings. - Stripe — payment processing. Subject to Stripe's privacy policy. - Vercel — hosting. - Resend — email delivery. Receives your email address and the content of the scheduled notes Sage sends you. Those notes carry a shared daily question and passage and an unsubscribe link, not your conversations, memory, or name. - Reforestation partners — receive no user data. 5. Data Retention and Deletion Memory summaries and session transcripts are retained in encrypted form until you delete your account or request deletion. Embeddings are retained alongside them and are deleted at the same time. If your subscription lapses, your encrypted memory is retained while you remain eligible to return. To request deletion: support@sagegreen.ai. 6. Children's Privacy Sage is not designed for or directed at children under the age of 13. 7. Changes to This Policy We will notify you of material changes through the application. 8. Contact support@sagegreen.ai. Sage Green AI PBC is a Delaware Public Benefit Corporation committed to operating in the interest of its users and the broader public.

Sage is a personal guide grounded in Stoic philosophy and the world's deepest wisdom traditions. It's not a therapist and not a chatbot — it's more like a very wise friend who listens carefully, remembers what matters to you across conversations, and asks genuinely helpful questions. Everything is private and encrypted. Your conversations are never used to train AI models. The more honestly you engage, the more useful it becomes.

Sage is offered by Sage Green AI PBC, a Public Benefit Corporation with a simple belief: that human flourishing and caring for our environment go hand-in-hand. With every paid month of Sage we plant a tree with our reforestation partners.

When you open Sage in the morning, it will naturally move toward intention: what matters most today, what might make that hard, and how you want to show up. You don't have to name these explicitly — Sage will find them through the conversation.

Open sessions work any time of day. Bring whatever is actually on your mind — a decision, a relationship, something weighing on you, or just a question you can't shake. There is no structure and no destination. Sage follows your lead.

When you open Sage in the evening, it will naturally move toward reflection: what actually happened versus what you intended, where your values held or didn't, and what deserves to be carried forward versus released before sleep. Sage will follow your lead and find the shape naturally.

Sage works differently depending on when you come to it — not because it follows a script, but because different times of day call for different kinds of thinking. You can always redirect to something else entirely, and Sage will follow.
