Privacy

Last updated October 6, 2026

This policy explains what Mental Health Tools stores when you use the site, who can see it, and how you delete it. The terms cover what the site is and is not. Accepting the terms does not turn research on.

What we collect

Account. The email you use for the magic link, and an optional display name. There is no password. The email stays in the sign-in system. It is not copied into assessment rows or research rows.
Assessments. Your answers, optional notes, how long the fill took, and the scores that instrument defines. A cloud save stores that on your account.
Invites. A guide or a Couples lens sender can send a fill link. The completed fill is stored on their account, labeled by role, not as a row you can later browse, unless you claim a copy of your own self-report where the product offers that. A Couples lens partner address lives only on an owner-only email outbox, so the invite can be sent. It is not stored on the assessment.
Headset sessions. Heart rhythm and Signal field, if you record while signed in, store a derived series: heart rate, a coherence ratio, and on Signal field a once-per-second alpha and band reading plus focus markers. Those pages do not upload the raw brain-wave file. The local EEG dashboard, if you use it, keeps raw EEG, pulse, and motion in this browser only and does not upload that recording.
Research, only if you opt in. Anonymized score summaries of your own self-reports, including headset summary scores but not the time series and not invite fills other people complete. Optional background — age band, gender, region, city or rural, education, work, ethnicity, relationship, ADHD or autism and how you identify it, depression or anxiety, PTSD, substance use, therapy, medication, veteran status, and how you found the tool — is stored only for the questions you answer. It travels with a research ID, never with your email.
Connection data. The companies that host the site and the database see ordinary connection data, such as IP address and browser, because that is how a page is delivered. This site does not add a separate analytics or advertising tracker.

How it gets to us

A cloud save, a sign-in, and a research opt-in leave your browser over an encrypted HTTPS connection and go directly to Supabase, which holds the database and the sign-in system. Cloudflare delivers the pages over HTTPS. We do not run a separate server in between.

A file you download, or answers you leave only in this browser, stay on your device. They are not sent.

A headset connects to this browser over Bluetooth. Only a derived series is sent, and only if you record while signed in, over that same HTTPS connection. The raw brain-wave file is not uploaded.

A Couples lens invite address is saved in the database over that same connection. Resend then sends the email. The message is the fill link and any note the sender wrote, not the assessment answers.

How we use it

We use this information to run the site, show you your results, let a guide see completed fills they sent, send a Couples lens invite email when you ask for one, and — only if you opt in — keep those anonymized score summaries. We do not use it to advertise, and we do not sell personal, assessment, or neural data.

Who else can see it

A guide sees completed fills they sent, and the label they gave that person. They do not receive Heart rhythm or Signal field recordings. A Couples lens sender sees the partner’s completed fill. Guides and partners are independent of this site. What they do with a result after they have it is their practice, not this policy.

The companies that operate the site are:

Cloudflare hosts the pages.
Supabase handles sign-in and the database.
Resend sends Couples lens invite email. The message contains the fill link and any note the sender wrote. It does not contain the assessment answers.

We may also disclose information when the law requires it, or if the service is transferred, under the same limits. The headset maker is not one of those recipients for data these pages store. Their own app, if you use it, follows their terms at choosemuse.com/legal.

Research copies

Research is off until you turn it on in Account. If you opt in, the contribution is a score summary and any background you chose to answer, under a research ID with no email. Invite fills and headset time series are not included. We do not try to put an email back onto a research row. Turning research off deletes those contribution rows. That choice is separate from using the site.

How long we keep it, and how you delete it

Cloud saves stay until you delete them. Signed in, Account lists those saves and can delete one. If research is on, the research copy for that instrument is rebuilt from what remains, or removed if nothing remains. You can turn research off without deleting the saves. Local browser storage lasts until you clear it.

There is no separate privacy desk and no payment account. Access and deletion for what this site stores are the Account controls above.

California

If you live in California, you can know and delete the personal information this site keeps by using Account, as described above. You can turn research off, which deletes the research copy. We do not sell personal information, and we do not share it for cross-context behavioral advertising. We do not charge a different price for using those controls.

Security

Sign-in is a one-time email link. Assessment rows are limited to the account that owns them. No storage or transmission system can be guaranteed completely secure.

Adults only

The site is for adults 18 and older. We do not knowingly keep assessment or headset data from anyone younger. If a save belongs to someone under 18, it should be deleted from the account.

Changes

We may update this policy and will change the date at the top when we do. Research stays off until you opt in, including after this policy changes.
