Privacy notice for the WA-Chain Edu early access list
Who we are
WA-Chain, a student-led team based in Sapporo, Hokkaido, Japan. We will give our full address promptly on request.
Contact: ezaki.yoshifumi.i1@elms.hokudai.ac.jp, or reply to your confirmation email.
What we collect
- Your name, country or region, type of affiliation, and email address
- The language you used, whether you asked for WA-Chain updates, and the date and time you registered
- The version of this notice you agreed to
- How you reached the page: the channel the link came through (for example, a direct message or an interview with us) and, if you used one, which button on our trial site. These are recorded from the link itself, using fixed labels only
- What you are most interested in, if you choose to tell us
To stop automated sign-ups, the form uses Cloudflare Turnstile, which checks signals from your browser. We do not receive those signals.
To count how often our pages are viewed, we use Cloudflare Web Analytics. It does not use cookies or store anything on your device, and it is not used to identify you. Your browser sends Cloudflare the address of the page you viewed, the page you came from, your browser type and how fast the page loaded. We do not use advertising cookies or tracking pixels.
Why we use it
We use your details only to provide WA-Chain Edu to you in the way that suits you best. In practice, this means:
- confirming your registration and telling you your place on the waitlist
- telling you about the release and how to access WA-Chain Edu
- replying when you contact us
- understanding, as overall numbers only, which countries and types of organisation need the service, which features interest people most, and how people found us, so that we can shape it for you
Only if you tick the optional box, we also send you occasional WA-Chain updates. You can stop them at any time.
We never sell your details or share them with anyone for their own purposes.
Where your details go
Your details pass through two companies only. Both are in the United States.
| Company | Role | Their privacy policy |
|---|---|---|
| Cloudflare, Inc. (USA) | Hosts this page, carries your submission to Google over an encrypted connection without storing it, runs the bot check, and counts page views (Web Analytics) | cloudflare.com/privacypolicy |
| Google LLC (USA) | Stores the waitlist in a private Google Sheet in WA-Chain’s account and sends your confirmation email through Gmail | policies.google.com/privacy |
Both companies act on our behalf. For the data protection system in the United States, see the summary published by Japan’s Personal Information Protection Commission: ppc.go.jp (United States). When you tick the consent box, you agree to your details being handled by these companies in the United States.
How long we keep it
- Until 1 November 2027 (one year after the planned release), or until you ask us to delete it, whichever comes first
- If you asked for updates: until you unsubscribe
After that, we delete your details. We may keep overall numbers that cannot identify you, such as how many people registered from each country.
How we protect it
- Every connection is encrypted (HTTPS). Your details are never put in web addresses or server logs.
- The spreadsheet is not shared with anyone. Only the team members who run the waitlist can open it, and the account uses two-step verification. Monthly counts for the wider team are written to a separate file that contains no names or email addresses.
- The link between this page and the spreadsheet is protected by a secret key that never reaches your browser.
Your rights
You can ask us to show, correct or delete your details, to stop using them, or to stop sending emails. You can also withdraw your consent at any time. Reply to your confirmation email or write to the contact above. There is no charge. If you live in the EEA or the UK, the legal basis is your consent, and you may also complain to your data protection authority.
Under 16
If you are under 16, please ask a parent or guardian before you register.
