AI shouldn’t be creepy
Ask your AI what it knows about you, and you might be surprised. Privacy is not the default setting with most AI providers.
Most account-based software begins with identity and accumulates information around it. Mix begins with the opposite assumption: collect as little as possible, anonymize what must be collected, and destroy what does not need to remain.
The problem with permanent AI history
Chatbots have become journals people never intended to write.
Users discuss illnesses, marriages, employers, lawsuits, investments, inventions, fears, negotiations, politics, finances, and business plans.
Those conversations can become extremely valuable records. If they are retained, they also become records that can potentially be compromised, requested through lawful legal process, or transferred as part of a corporate transaction.
That does not make conventional AI services improper. It means they are designed around a different relationship with the user.
Mix is designed for the questions you do not want to become part of a permanent AI history.
Privacy rule 1
If we don’t need it, we don’t want it
Mix does not need your:
Name
Home address
Phone number
Employer
Biography
Social profile
Advertising identity
Long-term history
Your Mix access is designed around a minimal email identifier and a credit balance. No password profile is required. No permanent Mix chat history is attached to that account.
Privacy rule 2
Billing and reasoning do not belong in the same system
Mix operates billing and reasoning on physically separate infrastructure. A one-time run authorization bridges the two systems. It says, in effect:
“This run may consume this much credit.”
It does not need to say:
“This is John Smith, and here is what John Smith wants to know.”
When the run is complete, the temporary authorization is finished.
Path A
Billing
One-time run
authorization
“This run may spend up to X credits. Accept?”
One-time run authorization
Path B
Reasoning
Use an anonymized card or crypto to pay - your prompts are anonymized.
Privacy rule 3
Anonymize personal information
Identifying information is substituted only when it is both:
Unnecessary to identify the customer
and not pertinent or critical to the analysis
If removing a fact would make the answer worse, the fact stays.
That is privacy with judgment, not privacy theater.
Privacy rule 4
Give each system only what it needs
Not every model necessarily needs every piece of information. Mix can route different representations and tasks to different models based on their role in the reasoning process.
The objective is data minimization. The smaller the necessary exposure, the smaller the privacy surface.
Privacy rule 5
Temporary work should stay temporary
A Mix reasoning run is designed as an ephemeral session. Temporary run identifiers are used instead of permanent conversational identities. Working state exists to complete the analysis.
Completed conversations are not added to a Mix chat-history database.
The goal is simple.
Finish the work
Return the answer
Stop retaining the conversation
AI model providers
Mix uses third-party frontier AI APIs. Those providers may process and, depending on the provider, model, contract, safety requirements, and applicable law, temporarily retain information sent to them.
That is why Mix anonymizes and minimizes what they receive.
Personally identifying information is substituted before external processing where doing so will not impair the answer. Mix also selects provider configurations and data-handling arrangements with privacy in mind.
We cannot promise that an outside AI provider never processes or retains any information under any circumstances.
We have designed Mix so those providers receive little to no personally identifying information.
No advertising business
Mix does not sell your question history.
Mix does not build advertising audiences from your questions.
Mix does not use your prompts to train a Modulus advertising profile.
Mix does not need to know what you asked last month to sell you something next month.
No tracking-cookie economy
Mix does not use advertising cookies, behavioral retargeting, session replay, third-party marketing pixels, or cross-site tracking.
Third-party payment providers may operate their own checkout infrastructure under their own privacy policies. That payment infrastructure remains separate from Mix reasoning.
Legal obligations
We comply with lawful obligations.
But a company can only produce records it actually possesses. Mix is deliberately designed not to maintain a permanent customer chat-history database.
Payment and account records may exist where necessary for billing, accounting, fraud prevention, or law. Temporary information may also exist while a run is being processed.
The privacy advantage is structural.
We minimize what exists in the first place.
If Mix gets acquired
The same principle applies.
A successor cannot inherit a permanent Mix chat-history database that Mix never built.
Account, credit, financial, legal, and operational records that Modulus is required or permitted to retain may still exist and may be handled according to applicable law and the governing privacy policy. But Mix’s product architecture is specifically designed to avoid accumulating permanent archives of customer questions.
Why Mix
Mix combines intelligence from different AI systems.
It also reflects a privacy principle familiar in cryptography and digital assets: identity and activity become safer when unnecessary direct linkages are not preserved.
Mix separates billing identity from reasoning activity, uses temporary authorization rather than a durable customer-question relationship, and minimizes identifying information before external reasoning.
The analogy is about separation. Not secrecy for wrongdoing. Privacy for ordinary people asking questions that belong to them.
Privacy is not suspicious behavior
You close your office door. You seal an envelope. You talk privately with your spouse. You use passwords. You shred sensitive documents.
You do not do those things because you are doing something wrong. You do them because some information is private and confidential.
Mix is built around the same idea.
