Terms of service, in plain language.

1.The service

Hachiflow provides managed hosting for Buzz, an open-source team workspace. We provision and operate a dedicated relay for your team (your "workspace" or "hive"), including the server, storage, backups, upgrades, security patching, and monitoring. Your team connects to it with the Buzz desktop app.

These terms are an agreement between you (the customer who signs up, and the organization you represent) and Hachiflow. By creating a workspace or using one we host, you accept them.

2.Accounts and eligibility

You must be at least 18 and able to enter a contract to open a workspace. If you sign up on behalf of a company, you confirm you are authorized to bind it to these terms.

Membership in a workspace always comes by invite from its owner or an admin. Signing in with an email on your organization's verified business domain does not by itself add you to that organization's workspace; it lets us recognize you as a colleague and pass an invite request to the workspace owner. Consumer email domains get no such recognition; those users need an invite link as well. You are responsible for who you invite and for activity that happens under your workspace.

Each subscription covers one workspace. If you need more than one, that is more than one subscription.

3.Price and billing

Hachiflow is one flat monthly fee per workspace, published on hachiflow.com. What you pay for is the workspace we run for you: one dedicated server and the storage that comes with it. The fee is not per user and not per agent, and adding teammates, human or agent, does not change what you pay.

The workspace includes the amount of storage published on the pricing page. Storage beyond the included amount is billed at the rate published there. Going past the included amount never blocks writes, refuses uploads or deletes content, and overage billing starts only after we have told you what you are using and what it will cost; we will not change what you pay without telling you first.

Billing is monthly in advance through Stripe, our payment processor. Prices exclude any applicable taxes, which you are responsible for. If a payment fails, Stripe retries it on its normal schedule; a workspace with an unpaid balance may be suspended after reasonable notice.

Price lock: workspaces keep their signup price for as long as the subscription stays active, even when list prices change.

Cancellation: you can cancel any time, effective at the end of the current billing period. The workspace stays fully usable until then. We do not refund partial months except where the law requires it.

4.Your data and ownership

Your workspace data is yours. The messages, files, event log, workspace configuration, and cryptographic keys in your hive belong to you, not to us. Hosting with us never transfers ownership of any of it.

We access your tenant infrastructure only to operate and support the service: provisioning, upgrades, backups, restoring from failure, and troubleshooting issues you report. We do not read your workspace content for any other purpose, we do not sell it, and we do not use it to train models.

On cancellation you can ask us for your data and we will hand it over: the database containing your signed event log, your media, your git repos, your workspace configuration, and your keys. You do not have to wait for us: a self-serve export of your signed event log, your media and your git repos is available in the dashboard at any time, and your keys are claimed separately there. That export is a verifiable record of your workspace rather than a running deployment, so rebuilding your workspace on other infrastructure is an operator-assisted handover, as is any workspace too large for the self-serve export path. Buzz is open-source software, so what you receive runs on the same software we were running for you. After your subscription ends we keep your data for 30 days so the handover can complete, then delete it, including backups.

5.Workspace names and subdomains

Your workspace lives at a subdomain of our domain, like yourteam.hachiflow.chat. The name (the "slug") is licensed to you for the life of your subscription; it is not property you own and it cannot be sold or transferred outside the service.

• First come, first served. Ordinary names go to whoever claims them first, the same way workspace names work on comparable platforms.
• Reserved names. Infrastructure names (like www, api, status), well-known trademarks, and abusive terms are blocked at signup.
• Verified-domain release. A reserved trademark unlocks automatically when your verified sign-in email domain matches it. Someone at microsoft.com can claim microsoft; someone at a consumer email domain never can.
• Trademark complaints. If a rights holder sends a documented trademark complaint about a slug, we review it promptly and may reclaim the slug. Squatting on names you have no claim to is not allowed.

Your workspace answers on that subdomain only, served over HTTPS. We do not serve workspaces on domains you own.

6.Acceptable use

Use your workspace lawfully and do not degrade the service for anyone else. Specifically, you may not:

• store or distribute illegal content, or use the service to violate anyone's rights;
• incite, threaten, glorify or organize violence against anyone, or use your workspace to support a violent extremist cause;
• give a workspace over to attacking or degrading people for who they are: race, ethnicity, national origin, immigration status, religion, sex, gender identity, sexual orientation, disability, or age;
• target an identifiable person for harassment, or publish private information about them without their consent;
• store or distribute sexual material involving minors, which we report to the authorities in every case and without notice to you;
• send spam or unsolicited bulk messages from your workspace;
• use agents to harass, deceive, impersonate, or attack people or systems;
• abuse resources: crypto mining, denial-of-service traffic, or workloads unrelated to running your team's workspace;
• probe, scan, or attempt to breach the isolation between tenants.

Agent inference runs on LLM API keys you bring. Those keys, the accounts behind them, and the costs they incur are your responsibility and your direct relationship with the provider. Keep your keys within the provider's terms; we scope them to your hive and never share them across tenants.

The law that applies is not only yours. Your workspace runs on a server in a particular country, over storage and networks operated by other companies with rules of their own. Content that is lawful where you are can be unlawful where your workspace actually runs, and a provider we depend on can require us to act on something no court has ruled on. Your workspace has to be lawful in both places.

We do not monitor your workspace. Section 4 means what it says: we do not read your content to police it, and nothing scans it looking for any of the above. We act when someone reports a workspace, when a court orders us to, or when one of our providers requires it. Responding to a report can mean looking at the specific thing reported, and nothing wider than that.

We may suspend a workspace that is actively harming others or the platform. Where the situation allows it, you get notice first and a chance to put things right. Where it does not, because the law, a provider, or ongoing harm to someone requires us to move the same day, we suspend first and tell you immediately afterwards, with the reason.

7.Availability

We run each hive on dedicated infrastructure with automated daily backups and a weekly automated integrity check of the newest backup, and we target high availability. Full restore drills are run by our team rather than on an automated schedule. We do not yet offer a contractual SLA or uptime credits. Current and historical status is published at status.hachiflow.com.

Planned maintenance is announced in advance where possible and scheduled to minimize disruption.

8.Third-party services

Buzz is an open-source project (Apache-2.0) by Block, Inc. Hachiflow is an independent hosting service and is not affiliated with, sponsored by, or endorsed by Block, Inc. Your use of the Buzz software itself is governed by its open-source license.

We rely on a small set of subprocessors to deliver the service (infrastructure, storage, payments, authentication). The current list is in our privacy policy.

9.Termination

You can end this agreement by cancelling your subscription (section 3). We can suspend or terminate a workspace for material breach of these terms, for legal necessity, or for non-payment, with notice and a chance to fix the problem where the situation allows it. It does not always allow it: a legal order, or an infrastructure provider requiring content gone, can force us to act within hours.

Whatever the reason the agreement ends, the data terms in section 4 hold: your data on request, deletion after 30 days. The single exception is material we are legally barred from handing over, or required to preserve for the authorities. If we ever discontinue the service as a whole, we will give at least 60 days' notice and keep handing over data for the full window.

10.Limitation of liability

To the maximum extent the law allows: the service is provided "as is", and our total liability arising out of these terms or the service is capped at the fees you paid us in the 12 months before the claim arose. Neither of us is liable to the other for indirect, incidental, special, or consequential damages, including lost profits, lost data beyond our backup obligations, or business interruption.

Nothing in this section limits liability that cannot be limited by law, such as liability for willful misconduct or fraud.

11.Changes to these terms

We may update these terms as the service evolves. For material changes we will email the workspace owner at least 14 days before the new terms take effect. Continuing to use the service after that date is acceptance; if you do not accept, cancel before the change takes effect and section 3 applies as usual.

12.Governing law

These terms are governed by the laws of the State of Colorado, USA, without regard to its conflict-of-law rules. Disputes will be resolved in the state or federal courts located in Colorado, and both sides consent to that venue. If any part of these terms is found unenforceable, the rest stands.
