Privacy policy
Effective date: October 27, 2026
N2 Traps is a small JLPT N2 practice-and-diagnosis service run by a solo operator in Japan. In this policy, “we” means that operator.
This page explains what we collect, how we use it, and how to request access, correction, or deletion. Contact: wenyan1973@gmail.com
What we collect
You can answer the 20 free questions anonymously. Submitting your answers for an emailed diagnosis does not require an account, but the submission includes your email address.
| When | Information collected |
|---|---|
| You submit the free diagnosis | Your email address, 20 answers, self-reported level, goal, and consent choice |
| You choose Google sign-in, when available | Your name and email address only |
| You choose email magic-link sign-in, when available | Your email address |
| You use account sign-in | Authentication session cookies needed to maintain your sign-in |
Optional sign-in is being added. Once available, signed-in users can view their past submissions as a record of progress.
We do not receive your Google password. We do not use advertising trackers or analytics pixels.
Why we use your information
We use the information you submit to:
- Review your answers and prepare your diagnosis. The operator writes and sends the diagnosis email manually within 48 hours of submission.
- Authenticate you and operate your optional account, including letting you view past submissions.
- Handle your requests about your information.
- Calibrate question difficulty using answer data in aggregate, de-identified form.
Removing an email address alone does not necessarily make information anonymous. Data used for aggregate calibration must not identify individual users.
Information received through Google sign-in—your name and email address—is used only to sign you in and operate your account.
Storage and service providers
Submissions are stored in a submissions table in Lovable Cloud, a managed Supabase service providing a Postgres database and file storage. Lovable/Supabase hosts the service and provides Supabase Auth for optional account sign-in.
The providers involved in delivering the service are:
| Provider or category | Role |
|---|---|
| Lovable / Supabase | Hosting, database, file storage, and account authentication |
| Google, if you choose Google sign-in | Processing your Google sign-in and providing your name and email address |
| Email service providers used by the operator and the authentication service | Delivering diagnosis emails and email sign-in links |
Google processes your sign-in under its own privacy policy. Email providers process the information needed to deliver the relevant messages, including recipient addresses and message contents.
We use service providers only as needed to provide the service. We do not sell personal information or share it with advertisers or data brokers. We do not publish individual submissions or results.
We do not transfer or disclose information received through Google sign-in except as necessary to provide the service or comply with law. The same limits apply to disclosure of other personal information.
Security
We are responsible for handling your information with reasonable care. Our security commitments include limiting access and use to what is needed to operate the service, protecting account and provider access, and handling personal information requests carefully.
Hosting and authentication rely on Lovable/Supabase’s managed infrastructure. No online service can guarantee absolute security.
Cookies
The only cookies we use are authentication session cookies needed to keep you signed in if you choose to use an account. We do not use advertising or analytics cookies.
How long we keep information
We keep submissions and account information while the service operates, unless you request deletion. This supports diagnosis delivery and access to past submissions.
Aggregate statistics that no longer identify anyone may be retained after personal information is deleted.
Your choices and requests
You can use the free questions without signing in. Submitting a diagnosis request requires the information listed above.
To request disclosure of the personal information we hold about you, correction, deletion, or an end to its use, email wenyan1973@gmail.com, preferably from the address you used for the service.
We handle requests manually. We may need to verify that the information belongs to you before disclosing or changing it. We will confirm the outcome by email. If we cannot fulfill part of a request, including because of a legal requirement, we will explain why.
Children
N2 Traps is not directed at children under 13. If you are under 13, please do not submit personal information. If you believe a child under 13 has submitted information, contact us to request deletion.
Payments
We do not currently accept payments. If payments are added, they will use Stripe Checkout, and this site will not receive card numbers. We will announce that change by updating this policy before payments begin.
Changes to this policy
We will publish changes on this page and update the effective date. Changes describing new collection or uses will be published before those activities begin.
