Superposition one plan, from requirement to decision Request access

Privacy policy

What we collect, why, who else handles it, how long we keep it, and what you can make us do about it. Written to describe what the software actually does, including the places where it does less than we would like.

Draft, and not yet reviewed by counsel. Placeholders marked [ ] are facts about the company rather than about the product, and are filled in before this takes effect.

1. Who we are

[Legal entity name and registration number] of [registered address] ("we", "us") runs Superposition and this website, and decides what happens to the personal data described here. Write to support@project-superposition.com about anything on this page.

2. The short version

3. What we collect, and why

Visiting the website

Nothing of ours. Our hosting providers, Vercel and Supabase, receive the technical details every web request carries, such as your IP address and browser, to deliver the page, and handle them under their own policies.

Asking the website a question

The "Ask about the product" window records every question: its text, the topic it matched, whether it was answered, the page you asked from, and any campaign tags in the link that brought you (such as utm_source). It records nothing that identifies you. We read the questions to decide what to build and what to write, and delete them after 12 months. Do not type personal information into it.

The contact form

Your email address, name, company, what you run today, your message, and any campaign tags in the link that brought you. We use them to reply to you, and only we can read them.

Creating an account

Your email address and a password, or a sign-in link sent to your address. Supabase handles sign-in; we never see your password. We keep when your account was created, when you confirmed your address, and when you last signed in, and Supabase records the IP address and browser of each sign-in, for security. Only a confirmed address, or one we invited before sign-up opened, can use the product. If we invited you then, we keep your address and a note of ours.

A personal address (from a public email provider) cannot create an organization. The account it made still exists until it is deleted, and we can see that it was refused.

Your organization

Its name, its email domain, the statement its creator made that they may create it (word for word, with who and when), whether it said its work is export-controlled, and its members: their roles, seats, how and when they joined, who is a key custodian and who appointed them, and who is waiting for approval. Members of an organization can see each other's email addresses, and project members can see each other's.

If you joined the waiting list, your answers to its questions: what you are working on, your industry, how you heard of us, and what you want from the product. You and we can read them.

Your programs

Everything you put in: projects, models, plans, tasks, comments and attachments. We hold it to run the service for you. Section 4 covers how it is protected.

A few seconds after you change a program, the application also sends us how many requirements, risks, tasks and milestones it has, and how many of them are verified, open or done. Numbers only, never names. We add them up across customers to see how much the product is used. When you read a notice in the product, we record that you read it, and when.

Planned, and off unless you turn it on: a feature that shares patterns seen in at least three unrelated organizations — never text, values or identifiers — to improve what every customer is offered. You would see every file before it left.

Seeing who else is in a project — not switched on yet

Not switched on yet. Our hosted service refuses presence connections until we apply the rules that admit only a project's members, and set it to refuse any channel those rules do not cover. Until then, the application says presence is off.

When it is on, a project's other members can see that you have it open, and you can see them. We show it so people working on the same project can see each other, and use it for nothing else.

Your browser shares your member identifier, a random identifier for the browser tab, the name of the branch you are in, and the commit you are looking at, which can be an autosaved draft. It also shares the kind of view you have open, the identifier of the element that view is for, the identifiers of up to 20 elements you have selected, and whether you have been active in the last two minutes. It shares identifiers, never the names, text or values of elements. Your display name, which today is your email address, is not shared this way: each member's browser shows it from the project's member list. To join, your browser also sends the project's identifier and its sign-in token, so the service can check you are a member.

An element marked export-controlled, or not yet assessed for export control, is never sent: not its identifier, and not a count. Others see only that your selection is not shared.

Presence travels over Supabase Realtime, part of the same Supabase project that holds your data. It is held in memory only while you are connected, by Realtime and by the browsers of members who have the project open. It is dropped when you close the project or lose your connection, and it is never written to our database or to the project's history. Realtime runs in several regions, and your browser connects to the nearest one. While you are connected, your presence can pass through regions outside the United States and be held in memory there. Supabase's connection logs may record when your browser joined and left the project's channel, and technical details such as your IP address, but not what you had selected.

When presence is switched on, it is on for every project, and other members can see you from the moment you open one. The first time you open a project's design view with presence working, the application tells you, once per project in each browser. To turn it off, open "Who's here" and choose "Hide my presence". While you are hidden, your browser does not connect at all. Nobody sees you, and you see nobody else. The choice is kept in your browser (section 6) and covers every project you open there afterwards. A tab already open elsewhere stops sharing when you reload it. Without our hosted service, presence is off.

Presence is for display only. It is not a record that anyone saw anything. The service checks that a browser belongs to a member, but not which member it claims to be, so one member could appear as another.

The assistant

When you ask the assistant a question, your browser decrypts the parts of the program the question is about and sends them, with the question, through our service to Anthropic, which runs the model. We store who asked, when, which model, the tokens used, what it cost, and a digest of what was sent — never the question or the answer. Your organization's members can see those records.

Connecting an AI agent

If you connect an AI client such as Claude to your program over MCP, you sign in and approve it. Our connector then lets it read your projects, tasks, schedule, risks and earned value, and propose changes that wait for a person; each proposal is labelled with the client's name. To answer it, our server decrypts the parts it asks for.

The credential the client is given carries your own access. It is refused your organization's key on its own; only our connector can fetch the key with it, on your behalf. Everything else you can do, it can: read what we store unencrypted (section 4), change your projects' records, including pointing a project at a different saved version of itself, which skips the review a proposal waits for, and act on your account itself, which a client set on misusing it could turn into a way to your program. Connect only clients you would trust with your own account. Supabase keeps the client's registration, your approval and its session; our own code keeps no copy of its token. What the client does with what it reads is governed by your agreement with its provider.

Problem reports

Only when you choose to send one, and only after you have seen what it contains. An automatic crash report carries a random identifier for your installation, the release, your operating system family, which parts of the product you were using, the shape of your last few actions and of your program (counts and statuses, never names), and where the error happened in the code — never the error's message or any of your content. A report you write yourself also carries your title, your description and up to three screenshots. Either kind carries your account if you are signed in, and your organization if you belong to exactly one, so that deleting the organization deletes the report. We keep a copy in your browser.

We read reports on our own machines and on build servers we rent from GitHub, and we triage them with the help of AI models from Anthropic.

Feedback

What you write, its kind and severity, and your account. If you leave the box ticked, which it is by default, also your browser's description of itself and the page you came from. We use it to reply to you and to fix things, and for nothing else.

Billing

Stripe takes your card; it never reaches us. We keep the references Stripe gives us, your seats, the price and the dates. From each message Stripe sends us about your subscription, we keep only its references, amount, currency and status. We never keep the billing name, email or address Stripe holds, and from a message we do not act on we keep only its identifier and type. We keep these as financial records.

Email we send you

Messages about your account: access being granted, somebody asking to join your organization (which includes their address), the reminder before a trial ends, changes to what the assistant costs, and anything about deleting your organization. Resend delivers them. Some of these, and alerts about failures, also reach our own mailbox, and can include your address and, for a deletion, the reason given.

Product updates and the newsletter — not sending yet

When we start: you choose to subscribe, on the website or with an unticked box when you sign up, and you confirm from an email before anything is sent. We keep your address, what you chose to receive, the exact wording you agreed to and when, and when you confirmed. We record when an email is delivered, opened or clicked, and when it bounces or is marked as spam, to know whether it is worth sending. Every email has a one-click unsubscribe that takes effect at once.

4. How your program is protected, and where that stops

Program content is encrypted with AES-256-GCM before it is stored — in your browser, or on our server for what an AI client writes through our connector — using a key derived for your organization. What sits in our database is ciphertext. Your organization's key is kept wrapped by Amazon Web Services' key management service.

That protects a stored copy, not against us. For your members' browsers to read the program, our service unwraps the key and hands it to them over an encrypted connection, and our MCP connector decrypts on our server what an AI client asks for. We do not look at your content, but we are not technically unable to.

Some things are not encrypted, because the database has to look them up or because they were never program content: project names and descriptions, the email addresses of people you invite, feedback, waiting-list answers, problem reports and their screenshots, the reason given for a deletion, the counts described in section 3, and a digest of each stored item. Content saved before encryption was introduced, and branch names saved before they were encrypted, are stored unencrypted too.

Access is checked in the database, not only in the application: only a project's members can read it, and only its editors and administrators can change it.

5. Who else handles it

Our database and keys are in the United States, in Amazon Web Services' us-east-2 region (Ohio). If you are elsewhere, using the service transfers your data there, [transfer safeguards — to be drafted by counsel]. Superposition is not FedRAMP authorized, and neither are Supabase or Vercel, which hold your data; if your program is export-controlled, talk to us before putting controlled technical data into the hosted service.

6. Your browser

We set no cookies. The website and the application keep a few things in your browser's local storage so they can work: your signed-in session, your theme, the last project you opened, how you arranged the panels, planner layout, whether autosave is on, how far you got through the tour, the page to return to after signing in, the random identifier used in problem reports, whether you have hidden your presence, and which projects have shown you the presence notice. The application also keeps copies of problem reports you saved or sent, with their screenshots, and projects from an earlier version that worked only in the browser. Clearing your browser's site data removes all of it.

7. How long we keep it

A job deletes each of these every day once it reaches the age below, counted from when we received it:

Everything else has no fixed period:

8. Deleting it, and your rights

An organization can have all of its programs destroyed. A key custodian orders it, every administrator and custodian is told, and it happens after seven days unless a key custodian cancels it. Destroying the encryption key makes the encrypted content unrecoverable, including in backups. Then the organization's programs, their history, the feedback its current members have sent, the problem reports sent from it or by its current members with their screenshots (except copies we have downloaded, section 7), its assistant records and its waiting-list answers are deleted from the live database. What was never encrypted (section 4) stays in backups until they expire. We keep that the organization existed, its members and their roles, its billing records, the record of its key and of the deletion itself. The terms of service describe how it is ordered.

A person cannot yet delete their own account from the product. Write to support@project-superposition.com and we will do it by hand. Deleting an account deletes its memberships, its feedback, its waiting-list answers and its problem reports with their screenshots (except copies we have downloaded, section 7). Projects it created stay with its organization, and the organization's records that it used the assistant stay, without saying who. If the account ordered or cancelled an organization's deletion, that record keeps an identifier for the account, which no longer leads to an email address, because the record is the proof of who decided.

Two things cannot be deleted on request, and we would rather say so. Questions asked of the website carry nothing that identifies you, so neither you nor we can find yours. That is deliberate, and it is why they are deleted after 12 months. A problem report sent while you were not signed in carries no account either, and is deleted with the rest after 12 months, and its screenshots after 90 days.

You can ask us for a copy of your personal data, to correct it, to delete it, or to stop using it for a purpose you object to, and you can export your programs from the product at any time. We answer within 30 days. [Your right to complain to a supervisory authority, and which one — to be drafted by counsel.]

9. Children

The service is for organizations and is not meant for anyone under 16.

10. Changes to this policy

We will post any change here with its date, and tell each organization's administrators by email [notice period] before a change that affects how we use data they have already given us.

Effective [date].
