1. Who we are and what these Terms cover
These Terms of Service ("Terms") govern the Stella service operated by FROMYOU, LLC, a Delaware limited liability company ("FROMYOU," "we," "us," or "our"), including our hosted backend and APIs, websites, and official desktop, browser, and mobile applications (together, the "Service"). They also cover our hosted agent execution, Drive, sharing and app-hosting features, and Stella Crew for Slack when you use those features.
By using the Service, you agree to these Terms. If you use it for an organization, you represent that you have authority to bind that organization; "you" then includes that organization. If you do not agree, do not use the Service.
Stella's code is provided under the MIT License, except components identified as having other licenses. These Terms do not restrict rights granted by those licenses. Section 12 addresses self-hosting.
Our Privacy Policy explains our handling of personal information. It is not permission to use your data for purposes beyond those described there.
2. Eligibility and accounts
You must be at least 13 and old enough under applicable law to use the Service. If you are under the age of legal majority where you live, a parent or legal guardian must review and agree to these Terms and supervise your use. We do not knowingly offer the Service to children under 13.
A Stella account is required to use our hosted assistant service. You can authenticate using the available email or social sign-in methods. Visiting public pages or opening a public share link does not require an assistant account. You are responsible for keeping your account, devices, sign-in links, API keys, and connected accounts secure, and for activity you authorize through them. Let us know promptly if you suspect unauthorized access. You are not responsible for unauthorized activity to the extent applicable law provides otherwise.
3. What Stella does
Stella coordinates AI agents that can work on your computers, in your browser and applications, with connected accounts, and in hosted sandboxes. Capabilities include reading and changing files, executing commands, using websites, sending communications, working with repositories, generating media, scheduling work, creating apps and previews, and synchronizing conversations and files across devices.
You can use Stella-managed AI, supported provider API keys such as OpenRouter, or supported engine accounts such as Claude or ChatGPT. Availability depends on the client, execution location, connected accounts, plan, provider restrictions, and server configuration. Not every feature is available on every route or plan. Your own engine login or key does not make all hosted features free or prevent conversation and task records from being stored by Stella.
Stella is a research preview. Features may be incomplete, unreliable, changed, or discontinued. We do not guarantee uninterrupted availability or that any particular model, provider, integration, or feature will remain available. We will honor applicable notice, refund, and other consumer obligations when we change or discontinue paid services.
4. Your direction and responsibility for agents
Stella is a tool acting under your direction. You are responsible for the tasks, access, permissions, and instructions you give it, and for the actions agents take on your behalf, to the extent permitted by law. This applies whether work runs on your computer, another device, a hosted sandbox, a schedule, or a connected account.
An instruction may require intermediate steps and access to relevant content. Grant only permissions you are authorized to grant and that are appropriate for the task. You must have the necessary rights to the files, accounts, systems, personal information, and other material you direct Stella to use. A request to do work is not permission to access someone else's systems without authorization or to disregard the law.
AI can misunderstand instructions, follow misleading material, produce incorrect outputs, and perform unintended or irreversible actions. Examples include purchases or payments, messages or posts sent to others, files changed or deleted, credentials exposed, code executed or deployed, and actions in third-party accounts. Tasks may continue in the background or run later under a schedule.
Review important actions and verify their results. Keep backups; check recipients, amounts, permissions, generated code, and deployment targets; and do not give agents access to systems where a mistake would create a risk you cannot accept. Revoke access or stop work when needed. A cancellation may not undo an action already performed or a request already sent to a third party.
Stella may request confirmations and apply security checks. These safeguards are not guarantees that every consequential action will be caught or that every result will be correct. Approval of a task can cover its related steps without a new prompt for each step. Do not rely on an agent as the sole decision-maker for safety-critical, legal, medical, financial, or other consequential decisions; obtain appropriate professional advice where needed.
FROMYOU does not undertake to supervise, individually review, or approve each action taken in response to your instructions. To the extent permitted by law, FROMYOU is not responsible for agents' actions or outcomes on your behalf, including purchases, communications, file changes, deployments, or third-party account actions. This allocation of responsibility does not exclude our own liability where the law does not allow it; sections 15 and 16 apply.
5. Your content and data
You retain your rights in your inputs, files, conversations, and other content. As between you and FROMYOU, we do not claim ownership of outputs generated for you. AI outputs may not be unique, accurate, protectable by copyright, or free of third-party rights. You are responsible for reviewing them and obtaining rights needed for your use.
You authorize us and the service providers needed for features you choose to host, process, transmit, reproduce, and display your content only as necessary to provide, secure, maintain, and deliver the Service and comply with law. This includes submitting relevant context to the selected AI provider, synchronizing devices, executing tasks, and displaying content to recipients or collaborators you choose. It is not permission to sell your personal information, use private conversations for advertising, or train generalized AI models on your conversation content.
Ordinary conversations and task records are stored in our hosted infrastructure, including when agents run locally or use your own engine. Files and credentials may also remain on a device or be stored for hosted work. The Privacy Policy describes those distinctions. Deleting an application or a local cache does not delete hosted content.
6. AI engines and connected services
Prompts, attachments, conversation context, tool results, and other task content may be sent to named third parties that provide AI, search, media, or integration services. See the Privacy Policy and in-app AI data-sharing disclosure for recipients and routing. Provider availability and data practices can differ; we do not promise zero retention by every provider.
When you connect a Claude, ChatGPT, or other engine account or supply an API key, you authorize the supported use of that account or key for your requests. You remain responsible for the provider's fees, usage limits, account permissions, and terms. Account connections and credential availability can depend on where work runs. We do not sell you rights to a third-party subscription or guarantee that a provider will permit or continue a particular integration.
Connecting another service authorizes Stella to perform the actions within the access you approve and the tasks you direct, including ongoing or scheduled tasks. Disconnecting access does not undo completed actions or remove copies already stored in conversations or by the other service. Third-party services, websites, MCP servers, models, skills, and extensions have their own terms and privacy practices. Review them before granting access. Nothing here limits your rights against us for our own conduct under applicable law.
7. Free allowance, paid plans, and billing
Our hosted Service offers free and paid plans. The free plan includes a one-time managed-use allowance, not a recurring promise of unlimited or periodically renewed free inference. Paid plans offer the limits and capabilities shown at purchase. Some capabilities require a paid plan even if you bring your own model account or key. Usage can include model inference and other metered hosted work; the plan display explains applicable allowances and limits.
The price, billing interval, included features, usage limits, and any applicable taxes are disclosed before purchase. Paid subscriptions automatically renew for the disclosed interval unless canceled. By subscribing, you authorize recurring charges to your selected payment method through the applicable billing provider. Website and desktop subscriptions are processed through Stripe. If a subscription is offered through Apple or Google, that store's billing and subscription rules also apply, and you must manage that subscription through the store.
Usage limits can operate over more than one time window. We may restrict managed or hosted features when an allowance or limit is reached. An allowance has no cash value and is not transferable. Where extra-use credit is offered, it is a separate one-time purchase at the price shown, not a subscription renewal or a guarantee that every capability becomes available. Buying a plan or credit does not cover charges your own model provider, connected services, or self-hosting infrastructure bills to you.
You can cancel through the available billing-management controls. Cancellation generally stops the next renewal, and access to paid features continues until the end of the paid period. Uninstalling an app does not cancel a subscription. A recorded in-app account-deletion request turns off hosted Stripe subscription renewal, with failed billing updates retried hourly; the customer record and any remaining subscription are closed when final deletion runs after the recovery period. Signing in to cancel deletion does not automatically turn renewal back on. Check that any separately store-billed subscription is also canceled.
Except where required by law, by the applicable store, or expressly offered by us, fees are nonrefundable and we do not provide refunds for a partly used billing period or unused allowance. This does not limit mandatory cooling-off, withdrawal, refund, or other consumer rights. Contact contact@fromyou.ai about a billing error or refund request.
We will give reasonable advance notice of material changes to subscription prices or paid-plan terms, obtain consent where required, and allow you to cancel before a change affects a renewal. Price changes do not retroactively increase a period already paid for.
8. Drive, sharing, hosted apps, and previews
Drive and hosted workspaces store files for use across your devices and agents. If you create a public share link or publish an app, site, or public preview, anyone with the link or address may be able to access it without a Stella account. Recipients can copy or redistribute content. A preview is not necessarily private merely because it was created from a private project. Check the selected audience and access settings before publishing; do not publish secrets or personal information you are not entitled to share.
Deleting a source file is not necessarily the same as deleting a separately published copy or link. Removing access through available controls cannot recall content others already downloaded, cached, or copied. Contact us if you need help removing hosted public content.
You are responsible for generated projects, code, apps, and deployments, including their security, permissions, legal compliance, content, and any commitments you make to their users. Hosting a project does not mean FROMYOU endorses it or provides a security audit. We may remove or restrict hosted content that violates these Terms or threatens security.
9. Stella Crew for Slack
Stella Crew works within the Slack workspaces, threads, and connected repositories enabled for it. Instructions, code, activity, outputs, and previews can be visible to the workspace members, thread participants, repository users, or preview audience permitted by those services and settings. Workspace or repository administrators can control access and integrations.
If you install or administer Crew for an organization, you must be authorized to connect the workspace, repositories, and credentials; inform affected users as required; and establish appropriate instructions and access permissions. Members must not direct Crew to disclose information to an audience that is not entitled to receive it. Slack, GitHub, and other connected services have their own policies and retention rules. Deleting an individual Stella account does not necessarily remove an organization's Slack messages, repository changes, or other members' records.
10. Acceptable use
Do not use our Service to:
• Break applicable law or infringe others' rights, including privacy and intellectual-property rights. • Steal credentials, distribute malware, gain unauthorized access, commit fraud, or abuse or harass others. • Publish unlawful content, including child sexual abuse material, or direct agents to cause unlawful harm. • Circumvent our access controls, free-allowance eligibility, billing, or usage limits; interfere with the Service; or exploit security flaws instead of reporting them responsibly. • Resell our hosted access or managed credits without our permission.
These restrictions apply to our Service, not to rights the MIT License grants in the source code. They do not prohibit lawful inspection, modification, reverse engineering, self-hosting, or building competing software under applicable open-source licenses.
11. Software, branding, and third-party components
Stella code made available under the MIT License may be used under that license. Components with their own notices or licenses remain subject to those licenses. These Terms do not replace or amend open-source licenses or revoke rights they grant.
The Stella name, logos, and FROMYOU branding are not licensed for use as your own branding or to imply our endorsement. Open-source code permissions do not authorize access to our hosted infrastructure, paid credits, third-party accounts, or provider subscriptions without the required authorization.
Modifying an app or installing a third-party skill, extension, or MCP server can change its behavior and data access. You are responsible for choosing and reviewing modifications and third-party components you use.
12. Independently operated and self-hosted servers
When you run Stella on your own server, you operate it and control its data; FROMYOU does not receive or process that server's data. These Terms and our Privacy Policy cover only our hosted Service and official apps, not your server. Official apps may still contact app stores or Expo for downloads and OTA updates, and, if you enable it, our push relay for notification delivery. Those limited official-app services remain subject to these Terms and our Privacy Policy.
13. Account deletion and ending use
You may stop using the Service at any time and request deletion through Settings → Account → Delete account. Once the in-app request is recorded, your hosted account is disabled and signed out on all devices, subscription renewal is turned off, and we send a confirmation email. You have a seven-day recovery period: signing in during it cancels deletion and re-enables the account, but does not automatically resume subscription renewal. After seven days, a background process deletes eligible hosted account data and sends a completion email, usually within a day after the recovery period ends. The Privacy Policy and https://stella.sh/delete-account explain the process and limited retained records. You may also email contact@fromyou.ai for a manually handled deletion request or assistance. Export wanted data before requesting deletion; copies held by your devices, recipients, organizations, and third-party services are separate.
We may suspend or terminate access for a material breach of these Terms, nonpayment, a security or abuse risk, a legal requirement, or discontinuation of the Service. Where reasonable and lawful, we will give notice and an opportunity to address the issue. We may act without advance notice when needed to protect users, security, or comply with law. Mandatory notice and refund rights still apply.
Termination of hosted access does not revoke rights already granted under the MIT License. Provisions that by their nature need to survive termination, including outstanding payment obligations, ownership and license provisions, liability limits, and dispute provisions, survive to the extent lawful.
14. No professional advice or guaranteed results
AI output is not guaranteed to be accurate, complete, lawful, suitable, or safe. Stella is not a substitute for independent professional advice, testing, supervision, or backups. You must evaluate outputs and actions before relying on them. We do not guarantee that generated code works, a task succeeds, an action can be reversed, or a third-party account remains available.
15. Warranty disclaimer
To the extent permitted by applicable law, the Service is provided "as is" and "as available," without warranties, express, implied, or statutory, including merchantability, fitness for a particular purpose, and noninfringement. We do not warrant uninterrupted, error-free, or completely secure operation or correct AI actions or outputs.
Nothing in these Terms excludes mandatory warranties, conformity obligations, reasonable-care duties, or other rights that cannot lawfully be excluded. The MIT License contains the separate warranty disclaimer for code provided under it.
16. Limits of liability
To the extent permitted by law, FROMYOU and its officers, employees, and agents are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or loss of profits, business, data, or goodwill arising from the Service. Subject to the same legal limits, we are not liable for losses caused by agents' actions taken on your behalf or third-party models, integrations, websites, or independently operated servers, including unintended purchases, communications, file changes, deployments, or account actions.
To the extent permitted by law, our aggregate liability for claims arising out of or relating to these Terms or the Service will not exceed the greater of (a) the amount you paid FROMYOU for the Service in the 12 months before the event giving rise to the claim and (b) US$50.
These exclusions and limits do not apply to liability that cannot legally be limited or excluded, including any applicable liability for fraud, fraudulent misrepresentation, willful misconduct, gross negligence, death or personal injury caused by negligence, or mandatory consumer or data-protection rights. They do not excuse our own conduct where applicable law makes us responsible. Where local law does not allow an exclusion or limit, the legally required standard applies instead.
17. Business-user indemnity
If you use the Service for a business or organization, to the extent permitted by law you will indemnify FROMYOU against third-party claims, damages, and reasonable costs arising from your unlawful instructions or content, violation of these Terms, or infringement of third-party rights, including through projects or actions you direct. This does not apply to claims caused by FROMYOU's own unlawful conduct, negligence, or breach of these Terms. We will promptly notify you of a claim and reasonably cooperate in its defense. You may not settle a claim in a way that admits liability or imposes obligations on us without our consent. This section does not impose an indemnity on consumers using the Service for personal purposes.
18. Governing law and disputes
Delaware law governs these Terms, without regard to conflict-of-law rules, except where mandatory law provides otherwise. Subject to mandatory consumer rights, courts with jurisdiction in Delaware will resolve disputes. If you are a consumer, this does not deprive you of protections of the mandatory laws of your country of residence or any right to bring a claim in your local courts. These Terms do not require arbitration or waive class-action rights.
19. Changes and general provisions
We may update these Terms, identify the revision date, and provide reasonable notice of material changes through the Service or by email. Changes apply prospectively. Where consent is required, we will obtain it; otherwise continued use after the notified effective date constitutes acceptance. If you do not agree, stop using the affected Service, cancel paid renewal, and export or delete your data as appropriate. Mandatory rights are unaffected.
If a provision is unenforceable, the remainder continues to apply. Failure to enforce a provision is not a waiver. These Terms and any expressly agreed purchase or organization-specific terms form the agreement for the Service; open-source licenses remain separate. Nothing creates an agency, partnership, or employment relationship between you and FROMYOU.
