Terms of service

What you can expect from Osmos, and what we expect from you. Written to be read, because terms nobody reads are terms nobody agreed to.

This is a draft, pending review. It has not been through a lawyer, and anything in square brackets is a detail still to be settled. Last updated 13 August 2026.

The agreement

Who it is with Osmos — operated by Sam Ethan Mathew, an individual rather than a company — and you, or the organisation you are signing up on behalf of, in which case you are confirming you may agree for them. Written notice of any kind reaches us at hello@withosmos.com.
When it starts When you create an account or connect an assistant. If you do not agree with what is here, do not do either.
Age You must be at least 13 to hold an account, or at least 16 if you are in the EEA or the UK.
Ownership

Your content stays yours

We claim nothing Your contexts, memory, and notes are yours. Using Osmos does not transfer any ownership of them, and ending your account does not either.
What we do need Permission to store your content, back it up, and show it to the people and assistants you have given access to — which is what running the service consists of. That permission covers nothing else, and it ends when the content is deleted.
What it is not used for Not training, not analysis, not marketing, and not sale. Nothing you write is sent to a third party to make Osmos work — see privacy for the whole list of who is involved and what each one gets.
Shared contexts are shared Publishing to a shared context makes that knowledge available to everyone with access to it, including after you leave, because the project it belongs to is not only yours. Your private notes stay private and go with you.
Using it

What we ask of you

Look after your account

Keep your credentials to yourself, and use the sharing controls rather than your login when you want someone else to have access. Tell us promptly if you think an account has been taken over. Until an address is verified it cannot accept an invitation, join by a share link, send an invitation, or create an organisation, which is deliberate.

Your assistants act as you

Anything an assistant you connected reads or writes is treated as done by you, because it was done with your access. Connect the ones you trust with what the context holds, and disconnect any you no longer want reading it.

Do not reach for what is not yours

No probing other people's contexts, no attempts to bypass the access checks, no automated traffic designed to exhaust the service. Rate limits exist and are enforced; working around them is a breach of this agreement rather than a puzzle.

Content that is not allowed

Anything unlawful, anything you have no right to store, and anything designed to attack whoever reads it next. A memory layer is read by other people's assistants; poisoning it is aimed at them, not at us.

Money

Plans and payment

The current prices and allowances are on the pricing page, and the rules below are the ones the code follows.

Free is a plan, not a trial It does not expire and it does not ask for a card. Reaching a Free limit stops the next addition; it never removes what you already have.
Pro renews until you stop it Monthly or annually, per person, charged through Stripe. Adding someone charges for the part of the period they will use; removing someone ends their access immediately and lets the seat count fall at renewal, since that seat is already paid for.
Cancelling runs to the end of what you paid for You keep Pro until the paid period ends, then the workspace returns to the Free limits with every context and every memory intact.
A failed payment gets 14 days Service continues for a fortnight while you sort the card out. An expired card is not a decision to leave.
Nothing is deleted for a billing reason Not on downgrade, not on cancellation, not when a payment fails. This is a term, not only a courtesy.
Refunds Cancel at any time and you keep Pro until the period you have already paid for ends, as above. We do not refund the unused part of a period, so cancelling early buys time rather than money back. Prices are in US dollars and exclude any tax we are required to add.
Price changes If a price changes, we will tell account holders by email before it applies to them, and it never applies to a period already paid for.
Honestly

What we do not promise

Stated plainly, because a product about inspectable knowledge cannot be vague about its own limits.

No uptime guarantee yet

Osmos is provided as it is. We work to keep it available and we take backups, but there is no service-level agreement today, and you should not build something that cannot tolerate an outage on top of one that does not have one.

No certifications

No SOC 2, ISO 27001, or HIPAA attestation. If your procurement needs one, tell us before you depend on us rather than after.

Assistants can be wrong

Osmos gives your assistants better-informed material to reason over. It does not make their answers correct, and what they produce is still their output and your responsibility.

Liability

To the extent the law allows, neither side is liable for indirect or consequential loss, and our total liability is limited to what you paid us in the twelve months before the claim. Nothing here limits anything that cannot lawfully be limited.

Ending it

You, at any time Cancel Pro from your billing settings, or ask us to close the account entirely and delete what it holds.
Us, rarely We may suspend an account that is breaking the rules above or putting the service at risk, and we will say which one and give you a chance to put it right where that is possible. A suspension for abuse is not a way to make a billing dispute move faster.
If Osmos shuts down You get notice and a window to take your data out before anything is removed. Announcing it afterwards would make the promise above worthless.

The rest

Changes to these terms A change that affects your rights is announced by email to account holders before it takes effect. Anything that only makes the wording clearer appears here with the date at the top updated.
Governing law These terms are governed by the laws of the Commonwealth of Pennsylvania, United States, and any dispute will be heard by the state or federal courts located there.
Questions Anything here that is unclear is our problem to fix — hello@withosmos.com, or the contact page.
