Cookie & privacy notice
Borel Sigma Inc. uses limited personal data to operate Naarv checkout and optional editorial emails (Morning coffee / Evening tea).
Essential cookies
Short-lived httpOnly cookies (naarv_dir_otp, naarv_dir_auth) verify your email OTP and keep a checkout session secure. These are required to complete subscription checkout and expire quickly (OTP ~10 minutes, auth ~30 minutes).
Newsletter consent
Morning coffee (08:00 local) and evening tea (16:00 local) emails are sent only when you opt in during OTP verification, or when you are added to a launch list with recorded consent. You can unsubscribe at any time via the link in each email; we store your reason to improve the notes.
Location
We may infer a coarse location/timezone from network country headers (for example Vercel edge country) to schedule local send times and show regional pricing. We do not sell this data.
