Privacy policy
How the Erlen sales site (https://erlen.jp) handles the information it collects.
This is a courtesy translation. The Japanese version prevails. （日本語版が正文です） If the two versions differ, the 日本語版プライバシーポリシー is the binding text.
1. What we collect
The only information this site collects is what you type into the application form (/en/apply).
| Name | Required. To contact you and to confirm who you are. |
|---|---|
| Email address | Required. To send the screening result, the payment link, and the download URL. |
| Affiliation | Optional. Leaving it blank has no effect on screening. |
| Operating system | Required. To tailor the setup instructions. |
| Claude Code experience | Required. To anticipate where you may get stuck during setup. |
| Intended use (free text) | Required. To judge whether the product fits you, and to improve it. |
| Answers to the five conditions | Required. For the automated screening. |
| Fit check result | Only if you took the fit check. Only the verdict (fit / conditional / not for you) is carried over. |
| Timestamp | Recorded automatically on the server, to keep applications in order. |
The answers you give in the fit check (/en/shindan) are never transmitted. The verdict is computed inside your browser, and only that verdict is kept temporarily in the browser.
This site has no analytics tool installed and uses no advertising cookies. It loads no external fonts and no external scripts.
2. Purpose of use
- Screening applications for the early release, and telling you the result
- Sending the payment link and the download URL for the product
- Important notices to purchasers (defect announcements, update distribution)
- Improving the product and the sales pages (aggregated so that no individual is identifiable)
We use it for nothing else. We do not send marketing blasts.
3. Disclosure to third parties
We do not provide or sell the information we collect to third parties. The exceptions are:
- When disclosure is required by law
- When it is necessary to protect a person's life, body, or property and consent is hard to obtain
Payments are processed by Stripe, Inc. We never receive or store your credit card details (Stripe handles them directly).
4. Storage and processors
Application data is stored in a Cloudflare D1 database that we manage. This site itself also runs on Cloudflare, so Cloudflare, Inc. is involved in storing the information as our infrastructure provider.
We keep the data for 3 years from our last contact with you, and delete it after that.
5. Requesting disclosure, correction, or deletion
On request from the person concerned, we will disclose, correct, or delete the information we hold. Contact us at the address below in a way that lets us confirm your identity. We accept deletion requests even after purchase (note that after deletion we can no longer reissue your download URL).
6. About the data inside Erlen itself
This is separate from this site's policy, but it matters enough to state plainly. The Erlen instance you build after purchase runs only on your own Cloudflare account. Your lab records, attachments, and user information never pass through our servers, and we cannot read or collect them. There is no telemetry built in.
The only outbound connections Erlen makes are to PubChem (the public API of the US NIH / NLM) when looking up compound information, and to Google's authentication endpoint for login.
7. Contact
For questions about this policy, or to request disclosure or deletion, write to gakushijob@gmail.com.
Business details are in the legal notice.
