Aparti
Last updated: November 14, 2026
This Privacy Policy explains what information Full Cycle Tech Corp ("Aparti", "we", "us" or "our") collects when you use the Aparti Support Calculator at aparticalculator.com and related services (the "Service"), how we use it, who processes it for us, and the choices you have. It is written to match how the Service actually works.
When you sign in. The email address you sign in with. If you sign in with a code sent to your email, we keep an account record: your email, the account identifier our sign-in provider gives it, when it was created and last used, and the campaign or access code you came through, if any. If you sign in with an access code, we record which code was used. We never see or store a password for a code sign-in.
When you request access. Your name, your role (such as attorney, paralegal, mediator or accountant), phone number, the number of people who would use the Service, your firm, court or whether you represent yourself, and any note you add. We keep these answers with your account, together with whether and when the request was approved and paid.
When you subscribe or buy. Your plan, its seats, its status, its renewal date, the Stripe customer and subscription identifiers, your consent to the Terms and to automatic renewal (with the version of the Terms you agreed to and when), and the record of each payment, cancellation, failed payment and refund Stripe reports to us. For a per-case purchase: the matter number as you typed it, the product, the purchase identifier and date, and a one-way fingerprint of the case's figures used only to tell one matter from another.
When you add people to your firm. The email addresses of the colleagues you invite to a seat, and when each joined or left.
When you enter a giveaway, subscribe to our newsletter or send feedback. The details you submit: your email and, where you give them, your name, firm and phone number, and the content of your feedback.
Case figures. Everything you type to build a case (incomes, deductions, tax details, children, parenting time, property) lives in your browser tab for that session. We do not store it on our servers. If you refresh or close the tab without saving, it is gone.
Saved case files. If you choose Save, the case file is downloaded to your own device. It contains your figures and any documents you uploaded, embedded inside it, so treat it as you would the documents themselves. We never receive a copy, unless you give the file to an AI assistant connected to Aparti (section 4); then we keep nothing from it.
Calculations. To compute a result, your case figures are sent to our calculation server, used to compute the answer, and returned to your browser. We do not keep them after answering, except for the usage records described in section 3.
Documents you upload. If you drop in a pay stub, W-2, 1099, tax return, FL-150 or another calculator's printout, the file is sent to our calculation server, which passes it to an AI service to read the figures, and is then deleted from our server. We do not keep the file or store it in a database. You can always type the figures in by hand instead.
Document requests. If you send a client a document request, the client opens the link without an account and adds documents there. Each document is read once by our calculation server, which keeps no copy, and by the AI service described above. The client's browser then seals the documents, and the figures read from them, with a key carried only in the link, which we never keep, so we cannot open what we hold. We hold the sealed files until a case file you save holds them, until you cancel the request, or until the request ends 7 days after you made it, whichever comes first; then they are deleted. For each request we also keep a record that holds no figure, name, document or matter number: your account, the party asked for, whether the other party's documents were asked for too, its state, its dates and its counts (documents read, documents and figures sent, and the size of the sealed files). We keep that record for 30 days after the request's 7 days are over, then delete it. Our logs record each step of a request (made, opened, read, sent, collected, cancelled, ended or refused, and why) with the account, the party and counts, never the link, a figure or a document.
The built-in assistant and drafting. If you use the built-in assistant, your question, the conversation and the case figures needed to answer it are sent through our calculation server to an AI service. If you ask the Service to draft a document, the case figures and the facts you enter for the draft are sent the same way. We do not store the content of these exchanges on our server.
Server records. When your browser talks to our servers, we record your IP address, browser type (user agent), the time, and the result of the request, to operate the Service, keep it secure and prevent abuse. These records live in our hosting provider's operational logs.
Usage records. We keep a small usage record in our own database: for each sign-in, the email, time, IP address, browser type, result and source; on a free account, how many documents it has had read each day; and, when you download or print a report, the kind of report, whether it was downloaded or printed, a random case identifier and a one-way fingerprint of the calculation it came from. The identifier and the fingerprint are made in your browser; the figures, names and documents of the case are never sent for this. When you open another certified calculator’s printout, we record which calculator printed it, under the same case identifier, but not the figure itself.
Administrative records. We keep a history of actions our team takes on an account (approval, payment, revocation, restoration), with the reason given.
Cookies and browser storage. We use cookies and your browser's local storage only to keep you signed in, keep the Service secure, and remember settings such as your report language. Our sign-in provider, Clerk, sets cookies needed for signing in. We do not use advertising cookies or third-party analytics trackers.
Do Not Track and Global Privacy Control. We do not track you across other websites, and we do not sell or share personal information, so there is nothing for these signals to switch off. We honor them nonetheless and treat a Global Privacy Control signal as a request to opt out of any sale or sharing.
You can connect Aparti to an AI assistant, such as Claude (made by Anthropic) or ChatGPT (made by OpenAI), through our connector at mcp.aparticalculator.com. This section describes what happens to information when you do. Our page "Use Aparti in Claude or ChatGPT" (aparticalculator.com/assistants) explains how to connect.
Your connection. Each connection is one person's sign-in to their own Aparti account, the same account as the website, made on our sign-in provider's page. Aparti never creates an account from the chat. The connection reaches no more than your account does on the website. You end it by removing Aparti from your assistant.
What the assistant sends, and what we keep. When you ask for figures, the assistant sends the facts of the case to our connector, which passes them to our calculation server. We compute the answer, send it back to the assistant and keep none of the facts after answering, as on the website. Aparti stores nothing from the conversation. The calculation itself uses no AI service, and we do not use what you send through an assistant to train AI models.
What the chat's maker holds. What you type in the chat, and the figures Aparti returns into it, are held by the chat's maker under its own terms and privacy policy, not ours, and we do not control them. The plan you are on decides whether they can be used to train the maker's models. On Claude Team and Enterprise, Anthropic does not train on your conversations by default. On ChatGPT Business, Enterprise and Edu, OpenAI does not train its models on data accessed from apps by default. On personal plans, whether your chats are used for training is a setting in your account. For a client's case, use Claude Team or Enterprise, or ChatGPT Business or Enterprise, and decide whether its terms meet your duties. Both makers can change these terms; read the current ones before you rely on them.
What we log. Our connector and our calculation server write a line to our hosting provider's logs at each step:
These lines never hold the case, a figure, your email, the sign-in token or a word of the chat. They are kept on a rolling basis set by our hosting provider.
The daily limit. Through an assistant, each person can make 40 calls a day that compute figures, counted by the Pacific day. To keep the limit, we count them in our own database: for your account, each day's count, whether the limit was reached that day and whether our team was told that day; never the case. We delete each of these records after eight days.
When the limit is reached twice in a week. If one person reaches the limit on two days within one week, our team receives one message in our team's Slack, at most once a week for that person. It carries the account identifier, its email, its firm's name, plan, seats and status (or, without a firm, the kind of access), the two days, the assistant it came through, and a link to the account on our administration page. We use it to notice unusual use and to follow up.
Reading a document for your AI assistant. When you ask Claude or ChatGPT to read a pay stub, W-2, 1099, 1040 or FL-150, it gives you a link to Aparti that works once, for 15 minutes, for your Aparti account only. While the link is open, Aparti's server holds only the link's code, your account, the party it is for and the assistant's name. You open the link, log in, and drop the document on Aparti's page, where it is read as any document you drop on Aparti. The document never goes to the assistant. The page lists the figures that will go back before you press Return. When you press Return, Aparti's server keeps those figures (for each one the party, the row, the monthly amount, the kind of document, two yes-or-no details the row needs, on a rental loss the part deducted this year, and whether you confirmed them or returned them as read) in its working memory for at most 10 minutes, until your assistant fetches them once; then they are deleted. Aparti keeps no copy of them on disk or in a database. Its logs record each step (a link made, opened, returned, fetched or refused, and why), the account, the party, which side acted and a count, never the link's code or a figure. A reduction read from a document stays on your case and does not go back.
Opening a case file in your AI assistant. When you give Claude or ChatGPT an Aparti case file, the assistant sends its facts to Aparti to compute, as it sends a case you describe. Aparti stores nothing from it. A file carrying documents, figures read from documents, documents attached to typed figures, a document request, or a Social Security number in any of its facts is refused.
Opening the case on the website. An "Open in Aparti" link from the assistant carries the case in the part of the address after "#", which your browser does not send to any server. The case opens in your browser like a case you type. Your browser's history keeps the address until you clear it, and the chat keeps the link.
We use information to:
We do not use your case figures or documents to train AI models, and we do not allow the AI services that process them for us to do so.
We do not sell your personal information. We share it only with the service providers that make the Service work, each for the purpose described, with an AI assistant you choose to connect (see the end of this section), and as the law requires:
When you connect Aparti to an AI assistant, the assistant's maker (such as Anthropic for Claude or OpenAI for ChatGPT) is not acting as our service provider for the chat: you choose it, and it handles what you type and what Aparti returns under its own terms (section 4).
We may also disclose information if the law, a court order or a valid legal process requires it, to protect the rights, safety or property of our users, the public or us, or as part of a merger, acquisition or sale of our business, in which case this policy continues to apply to it.
We protect information with encryption in transit, access controls, signed and expiring sessions, and by keeping as little as we can: we hold no case database and keep no uploaded documents, except the sealed files of a document request, which we cannot open. No system is perfectly secure; if we learn of a breach that affects your personal information, we will notify you as the law requires.
You can:
California residents. California law gives you the right to know what personal information we collect, use and disclose; to delete it; to correct it; to opt out of its sale or sharing; to limit the use of sensitive personal information; and not to be treated differently for using these rights. We do not sell or share personal information, and we use sensitive information only to provide the Service you asked for. To make a request, email [email protected]. We will confirm your identity by writing to the email address on the account, and you may use an authorized agent with your signed permission. Under California's "Shine the Light" law, you may also ask whether we disclosed personal information to third parties for their own direct marketing; we do not.
The Service is for adults and is not directed at children. We do not knowingly collect personal information from anyone under 18. Information about children that you enter in a case (such as age and parenting time) is part of your session-only calculation and is not stored by us.
We and our service providers process information in the United States.
We may update this policy as the Service changes. We will change the date at the top of this page, and if a change is material, we will tell you by email or in the Service before it takes effect.
Questions or requests about your information: [email protected].
