Summary
Last updated October 20, 2026
This is a plain-language summary. The full terms of service below is the legal text and always wins.
The service
Masterkey is an operating system for your company. Your people build their own screens, workflows and agents, and the agents run on your company's own data.
Masterkey LLC provides the service.
Your account
You sign in through the service's authentication, connect only accounts you own or administer, and keep your account secure.
Acceptable use
Connect only accounts you are authorized to use, never use the service to watch employees without their knowledge, and do not scrape, reverse-engineer or abuse the service.
Your data
You own what you provide and the results the service produces. Masterkey gets a limited license to process your data to run your company's screens, workflows and agents.
Team mode
Joining a company shares the work you do there with that company. A mailbox you connect stays yours: the company owner cannot read your private mail, and only the agents you run read it. You can leave a company at any time.
AI processing
Your data is analyzed by AI models that can be wrong. Your company chooses the level each agent works at: Drafts only, Asks first or On its own. An agent never sends anything to a person outside your company on its own.
Availability and liability
The service is provided as is, may change with reasonable notice, and liability is limited to what you paid in the 12 months before a claim.

Agreement
Masterkey LLC provides Masterkey. These terms are an agreement between you and Masterkey LLC.
By creating an account or using Masterkey, you accept these terms and the Privacy Policy. If you use Masterkey for a company, you accept them for that company and confirm you may do so.
The service
Masterkey is an operating system for your company. Your people build their own screens, workflows and agents, and the agents run on your company's own data.
Accounts
You sign in through the service's authentication and keep your account secure. Tell us at once if you think someone else used it. Your company's admins manage who belongs to the company.
Connected accounts and agents
Connect only accounts you own or administer. A connection belongs to the person who connected it.
Your company chooses the level each agent works at: Drafts only, Asks first or On its own. An agent never sends anything to a person outside your company on its own.
Your company is responsible for what its agents do at the level it sets, and for every action a person approves.
Acceptable use
Do not use Masterkey to break the law, to send spam, or to watch employees without their knowledge. Do not scrape, reverse-engineer, overload or abuse the service, and do not try to reach another company's data.
Your data and our license
You own the data you provide and the results the service produces. You give Masterkey a limited license to process that data only to run your company's screens, workflows and agents, as the Privacy Policy says.
Third-party services
Masterkey connects to services such as Google and Microsoft. Their own terms apply to your use of them, and Masterkey is not responsible for them.
AI output can be wrong
Masterkey uses AI models, and their output can be wrong or incomplete. Check what an agent produces before you rely on it.
Fees
A paid plan costs the price shown when you subscribe. You can cancel at any time; the cancellation takes effect at the end of the period you paid for.
Suspension and termination
You can stop using Masterkey and delete your account at any time. Masterkey can suspend or close an account that breaks these terms or puts the service or other customers at risk, with notice where the law allows it.
Disclaimers and liability
The service is provided as is and may change with reasonable notice. Liability is limited to what you paid in the 12 months before a claim.
Changes
When these terms change, the effective date at the top changes too. A material change is announced in the app or by email before it takes effect.
