Privacy policy
Last updated November 12, 2026
HLA365 is a study aid for histocompatibility and immunogenetics certification exams. It is operated by LabScienceLogistics LLC, a Florida company doing business as HLA365 ("we", "us"). This policy explains what we collect on the HLA365 website, and what we do not.
The short version: we collect your email address so you can sign in, and we record whether you own lifetime access. We do not run ads, we do not use analytics or tracking tools, and we never see your card details.
What we collect
- Email address. You enter it to sign in. We send you a sign-in link; there is no password.
- Account record. A random account ID, the date you created the account, and your last sign-in time.
- Access status. Whether you are in your free trial or own lifetime access, and which store the purchase came from (the website or Google Play).
- Purchase records. The product bought, the date, and a transaction reference. We do not receive your card number or other payment details.
- Messages you send us. If you email us, we keep the message and our reply so we can help you.
What stays on your device
Your quiz scores, practice-exam history and which questions you have seen are saved in your own browser's local storage. They are not sent to our servers. Clearing your browser data, or using a different browser, starts that history fresh.
Cookies and similar storage
The website uses your browser's local storage to keep you signed in and to remember your study progress. We do not use advertising cookies, analytics cookies or cross-site tracking.
Who handles your data
We use a small number of service providers to run HLA365. Each receives only what it needs to do its job.
- Supabase hosts sign-in and our database, in the United States. It holds your email address, account record and access status.
- RevenueCat records purchases and entitlements across the website and the Android app, so one purchase unlocks both.
- Stripe processes website payments. Stripe collects your card details directly and may also collect billing details such as a ZIP or postal code. We never see or store your full card number.
- Google Play processes purchases made in the Android app, under Google's own privacy policy.
We do not sell your personal information, and we do not share it for advertising.
How long we keep it
We keep your account and purchase records for as long as your account exists, and for as long afterward as the law or our accounting and tax obligations require. You can ask us to delete your account at any time (see below).
Your choices
You can ask us to show you the information we hold about you, correct it, or delete your account, by emailing hla365support@gmail.com from the address on your account. We will act on the request within a reasonable time. Deleting your account removes your sign-in and access record from our systems. Purchase records may be kept where the law requires. If you delete an account that holds lifetime access, that access is not recoverable.
If you live in a place with specific privacy rights, such as California, the European Economic Area or the United Kingdom, those rights apply to you and you can exercise them the same way.
The Android app
The HLA365 Android app does not require an account, and its quiz content and progress are stored on your device. Purchases in the app are handled by Google Play. Where the app lets you sign in to share your purchase with the website, the account information described above applies to that sign-in.
Children
HLA365 is written for adult laboratory professionals preparing for a certification exam. It is not directed at children, and we do not knowingly collect information from anyone under 13.
Security
Data is sent over encrypted connections and stored with providers that apply industry-standard safeguards. Access to our database is limited, and no one can read another person's account record through the website. No system is perfectly secure, so we cannot promise absolute security.
Changes to this policy
If we change this policy, we will post the new version here with a new "Last updated" date. If a change is significant, we will also tell account holders by email.
