Privacy Policy

Your privacy, in plain language.

Last updated September 23, 2026 Effective on launch Applies to the Maxwell app & website

Who we are

Maxwell is a health companion app for older adults and the people who care for them. This policy explains what information Maxwell collects through the app and this website, why we collect it, and the choices you have.

In this policy, "Maxwell," "we," "us," and "our" refer to Maxwell Labs, Inc., 5 Scott Street, Cambridge, MA 02138. "You" means the person using the app — whether for yourself or on behalf of someone you care for.

Information we collect

Information you give us

  • Account details — the name, date of birth, email address, phone number, and password you enter when you create an account. Your password is stored only as a secure, one-way hash; we never keep the password itself.
  • Profile information — anything you choose to add, such as a display name or details that help personalize your experience.
  • Connections you make — if you link your account with someone else's, we store that connection and the permissions you grant.

Two of those are worth saying plainly. We ask for your date of birth because Maxwell is for adults, so we use it to confirm you are over 18. We ask for your phone number so that services you request through Maxwell can reach you, and so we can contact you about your account. We do not send you marketing texts.

Information about how you use Maxwell

  • Content you provide — the messages, voice, images, and other information you enter into Maxwell or ask it to act on, so it can respond and keep context within your account.
  • Device & usage data — app version, device type, general diagnostics, and approximate location derived from information you provide.

Information from our website

  • Early-access sign-up — if you join the list on our website, we collect your email address and whether you are signing up for yourself or for someone else, and use them only to email you about Maxwell's launch. You can unsubscribe from any of those emails.
  • Visit data — like most websites, our hosting providers record standard technical information your browser sends, such as IP address, browser type, and the pages requested, to keep the site running and secure.

Health information

Some of the information you share with Maxwell relates to your health — for example, what you choose to record about it, and topics you raise in conversation. We treat this information as sensitive.

  • We use it only to provide the service you asked for.
  • We do not use your health information for advertising, and we do not sell it.
  • We share it with another person only when you have given explicit permission, and you can withdraw that permission at any time.

Please note

Maxwell is a wellness and support tool, not a medical provider. It does not diagnose, treat, or provide medical advice, and it is not a substitute for a doctor, pharmacist, or emergency services.

How we use information

We use the information we collect to:

  • Provide and personalize the service.
  • Send emails you have asked for or need — account and service messages, billing receipts, and notices you have chosen to receive.
  • Keep accounts secure, prevent abuse, and detect fraud or safety risks.
  • Understand how the app and website are used so we can fix problems and improve them.
  • Comply with legal obligations and enforce our terms.

We rely on a lawful basis for each use — typically your consent, the performance of our agreement with you, our legitimate interest in running a safe service, or a legal requirement, as applicable in your region.

How we share information

We do not sell your personal information. We share it only in these limited situations:

  • With people you choose — only with your explicit permission, and only what that permission covers. You can change or revoke it at any time in your settings, and if someone else linked your account to theirs, you can review and end that connection.
  • With service providers — companies that host our systems, deliver email, process artificial intelligence and voice, and provide other infrastructure, acting only on our instructions and under contract. They may not use your content to advertise to you, and we configure our AI providers so that your content is not used to train their general models.
  • For safety — to protect someone from serious harm, or to investigate fraud or abuse.
  • For legal reasons — to comply with the law, a valid legal request, or to enforce our terms.
  • In a business transfer — if Maxwell is involved in a merger, acquisition, or sale of assets, with notice to you.

Your choices & rights

Depending on where you live, you may have the right to:

  • Access the personal information we hold about you.
  • Correct information that is inaccurate or out of date.
  • Delete your account and associated data — you can do this yourself in the app, under Settings → Account settings → Delete my account.
  • Export a copy of your data in a portable format.
  • Withdraw consent — including ending access you have given someone else — at any time.
  • Object to or limit certain processing.

To exercise any of these, contact us at [email protected]. We will respond within the time required by applicable law. You also have the right to complain to your local data protection authority.

How long we keep data

We keep your information for as long as your account is active or as needed to provide the service.

When you delete your account, it is closed immediately and we wait 30 days before removing your information, so that a deletion you did not intend can still be undone — sign in again within those 30 days and choose "Keep my account". After that we delete your account and the information associated with it, and we ask the service providers that process it on our behalf to delete their copies. This cannot be reversed.

Two things deliberately outlive the account. Records of payments — what was charged, when, and to which account — are kept because a refund or a card dispute can arrive afterwards and has to remain explicable. And if someone else had shared their information with you, your access ends but their records remain theirs. We may also retain information where we must to meet legal, security, or accounting obligations.

Deleting your Maxwell account does not cancel a subscription bought through the App Store or Google Play. Those are managed by the store, and you need to cancel there as well.

How we protect data

We use technical and organizational safeguards — including encryption in transit, access controls, and regular review — to protect your information. No system is perfectly secure, so we cannot guarantee absolute security, but we work to protect your data and to notify you and the authorities if a breach occurs, as required by law.

Who Maxwell is for

Maxwell is designed for adults. It is not intended for, and we do not knowingly collect information from, children under 18. If you believe a child has provided us with personal information, please contact us so we can remove it.

Because many of our users are older adults, we aim to keep this notice clear and our privacy choices easy to find. If you need help understanding or exercising your choices, someone you trust or our support team can assist.

Changes to this policy

We may update this policy as Maxwell grows or as the law changes. When we make material changes, we will update the "Last updated" date above and, where appropriate, notify you in the app or by email before the changes take effect.
