Terms of use
Draft 0.1, 12 November 2026
Draft, not yet in force. Ostium is being set up and nobody can sign in yet, so it holds no personal data. This text describes how the service is built to work. It has not had its legal review; the final version and its date will replace this notice before sign-in opens.
In short
- Ostium is a free sign-in service in a pilot phase.
- You decide which services may use your sign-in, and you can withdraw at any time.
- You are responsible for the agents you connect and for keeping their tokens safe.
The service
Ostium ("the service") signs people and their AI agents in to the services that use it, and keeps a record of what each person has allowed each service to do. It is run by OÜ SOA Trader, registry code 11224441, Estonia ("we"). By signing in you accept these terms.
The services you sign in to are not part of Ostium. Each has its own terms and privacy policy, and is responsible for what it does.
Pilot status
The service is in a pilot phase and is free of charge. We may change, pause or end it; if we end it, we follow the notice promise in the privacy policy.
Your account
You sign in with a Google account. Keep that account secure: whoever controls it can use your sign-in and see your account page. You must be at least 18 years old. You can stop using Ostium at any time and delete your account on your account page.
Agents and organisations
You may register AI agents and create organisations. An agent token lets whoever holds it act as that agent in one service, so keep it like a password and revoke it if it may have leaked. You are responsible for what your agents do with your tokens, and an organisation's owners for what its agents do. Add a person to an organisation only with their agreement.
Fair use
Do not try to get around sign-in or consent, sign in as someone else, obtain other people's IDs or tokens, connect an agent in order to hide who is acting, or send traffic meant to overload the service.
Availability and liability
We work to keep the service available and correct, but provide it as it is, without guarantees of availability or fitness for a particular purpose. To the extent the law allows, we are not liable for indirect damage or for what a service you signed in to does. Nothing in these terms limits liability that cannot be limited by law, such as for intent or gross negligence, or your rights as a consumer.
Ending use
You can stop at any time. We may suspend access that breaks these terms or puts the service or others at risk, and will tell you why where we can.
Changes
We may update these terms. The version and date at the top show the current terms; for important changes we give notice on this site at least 14 days in advance. If you keep using the service after that, the new terms apply.
Law and disputes
Estonian law applies. We will try to settle any disagreement by talking first; write to info@soatrader.com. Otherwise disputes go to Harju County Court in Tallinn, unless the law of the country you live in as a consumer gives you the right to go to your own courts.
