Privacy policy
This policy covers the Kotsukotsu Nihongo pre-launch waitlist. It is written to be read, not skimmed past. Last updated: 10 November 2026.
Who is responsible
Infinity Wings ("we"), the publisher of Kotsukotsu Nihongo, registered with the Dutch Chamber of Commerce (KvK) under number 42197027, is the data controller for the waitlist. Contact: hello@kotsukotsunihongo.com.
What we collect, and why
- Your email address: to tell you when the app launches. This is the entire purpose of the list.
- Signup time, language, referral code: to know who joined first (early climbers enter first) and who referred whom.
- Campaign tags (UTM parameters): if you arrived from a link we posted, we record which one, so we know which posts were worth writing.
Nothing else. No tracking cookies are set by the waitlist form.
Legal basis
Your consent (GDPR art. 6(1)(a)), given by ticking the checkbox when you sign up. You can withdraw it at any time, see below.
Where it lives
The list is stored in a Supabase database. It is not shared with, sold to, or enriched by anyone. No advertising audiences, no "partners".
How long we keep it
Until launch plus a reasonable settling period. If you never activate an account, we delete waitlist data no later than 12 months after launch. If you unsubscribe, we delete your row promptly.
Your rights
Access, correction, deletion, portability, withdrawal of consent: email hello@kotsukotsunihongo.com from the address in question and it will be handled, no forms, no friction. Every email we send includes an unsubscribe link that works in one tap. You also have the right to complain to your local data protection authority.
Changes
If this policy changes before launch, the date above changes with it, and material changes will be noted in the one email you get from us.
