隐私

Last updated: 30 September 2026. This is a short placeholder until launch; the full policy will replace it before any paid features go live.

Your email address

If you join the waitlist, we keep your email address and preferred language to send the launch email and a monthly update. Our newsletter provider stores it on our behalf. We never sell or share it. Unsubscribe from any email, or write to hello@sumiyu.com and we'll delete it.

Analytics

We plan to use cookieless, privacy-first analytics that count visits without identifying you. No advertising trackers. If you dismiss the language suggestion bar, your browser remembers that choice locally.
