## What We Collect
Account Information
When you create an account, we collect your name, email address, and a securely hashed password. This is necessary to provide you with access to purchases, license keys, and trial activations.
Purchase Information
When you buy a product, payment is processed by Stripe. We store a record of your purchase (product, date, amount) and the license key issued. We do not store credit card numbers or payment details — Stripe handles this entirely.
License and Trial Data
We store license keys, activation counts, and trial expiration dates to enforce licensing terms and provide support.
Feedback
If you submit feedback through the site, we store the message content and your email address if you choose to provide it.
Analytics
We use Umami (cloud-hosted) for website analytics. Umami does not use cookies, does not collect personal data, and does not track individual users across sessions. It records aggregate page views and referrer data only.
Local Storage
We store an authentication token and your language preference in your browser's localStorage. These are not cookies and are not transmitted to third parties.

## Email Communications
We send the following kinds of email to people who have created a NOMN account:
Transactional emails — your trial license code at signup, password reset links, and purchase receipts with license keys. These are necessary to provide the service you asked for and are sent under GDPR Art. 6(1)(b) (performance of contract).
Service-related emails — when a trial expires, we may send a single message asking for honest feedback about your experience. This helps us improve our products and is sent under GDPR Art. 6(1)(f) (legitimate interest), with the right to opt out at any time.
Occasional product updates — when we ship significant updates or related tools, we may send brief announcements to existing account holders. This relies on the ePrivacy Directive Art. 13(2) "soft opt-in" exemption for similar products marketed to existing customers, and includes a clear way to opt out in every message.
We do not sell or share your email address with third parties for their own marketing purposes.
To stop receiving non-transactional emails, reply "no thanks" to any message or email hello@nomn.jp. We will permanently suppress your address from future non-transactional sends. Transactional emails (license delivery, password resets, purchase receipts) continue to be sent for as long as you have an active account, since they are necessary to deliver the service.
A separate Legitimate Interest Assessment for the service-related and product-update categories is kept on file.
