This ADHD guide is an educational resource. Your privacy matters here — especially because health is a sensitive topic. This page explains, in plain language, what is and isn't collected.
The short version
You can read the entire guide without an account and without giving any information.
Anything you fill in (self-check, medication tracker, notes) is saved on your own device unless you choose to create an account.
We don't sell your personal data. The site uses Google Analytics and may show Google ads, both of which can use cookies; see Analytics and Advertising below.
Information collected
Without an account: nothing is sent to us. Your self-check answers, medication log, notes, and display preferences are stored only in your browser (via local storage) on the device you use. Clearing your browser data removes them.
With an optional account: if you choose to sign in to sync across devices, we store:
your email address (to sign you in), and
the progress data you choose to save (self-check, tracker, notes).
Accounts and sign-in are handled by Supabase, our authentication and database provider. Your password is hashed by Supabase — this site never sees or stores your raw password.
How it's used
Solely to provide the service you asked for: to sign you in and sync your saved progress between your own devices. That's it. No advertising, no profiling, no selling, no sharing with third parties beyond the hosting/auth provider needed to run the site.
This applies to your account data. The site also uses analytics and, where enabled, ads, as described below.
Storage & security
Account data is stored with Supabase and transmitted over encrypted connections (HTTPS).
Access rules ensure each account can only ever read or change its own data.
No system is perfectly secure, so we keep what we collect to the minimum — an email and your own saved progress.
Cookies & local storage
This site uses your browser's local storage to remember your preferences and (if you don't sign in) your saved progress. If you sign in, a secure session token is also stored so you stay logged in.
Analytics
To understand how the site is used, it uses Google Analytics (through Google Tag Manager). It collects usage information such as the pages you view, your device and browser type, your approximate location and how you arrived, and may set cookies to do so. It never receives your account email or saved progress. See how Google uses information from sites that use its services.
When you click a link to our companion study app, Cadence, we record an anonymous count: which link, the page language and the page path. No personal identifiers are stored.
Advertising
This site may show ads to stay free. If ads are enabled, they are provided by Google AdSense, and:
No ad and no advertising cookie loads until you make a choice on the consent banner.
Choosing "Non-personalised" shows ads without personalisation cookies.
Google may use cookies to serve ads based on your visits to this and other sites; you can review and control this at Google Ad Center and Google's ads policy.
We block sensitive ad categories where possible and keep ads out of the personal, faith, and crisis sections.
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
You can opt out of personalised advertising in Google Ads Settings, and opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.
Some product links are affiliate links (marked as sponsored). If you buy through them, the site may earn a small commission at no extra cost to you.
Your choices & rights
Use it anonymously — never create an account.
Delete everything, anytime — open the sign-in panel and choose "Delete my account & data." This permanently removes your account and all synced data. To clear device-only data, clear your browser storage.
Access or correct your data, or ask a question — contact us below.
Depending on where you live, you may have additional rights (access, portability, erasure, objection). We honour these.
Data retention
Account data is kept until you delete your account. Device-only data lives on your device until you clear it.
Children
This guide is intended for a general adult and teenage audience. It is not directed at children under 13, and we do not knowingly collect data from them.
