Privacy policy

Account data

When you create an account we store your email address, your name, and, if you use Google sign-in, your Google profile name and picture. We also store what you save in the product: watchlists, alerts, journal entries and preferences. We use it to run your account and nothing else.

Visitor ID cookie and usage events

When you visit without an account we set one first-party cookie named hk_vid. It holds a random identifier (no fingerprinting, no IP address, no device data) signed so it cannot be forged. We record simple usage events against that identifier: the pages you open, when a visit starts, which locked sections you see, and whether you open or dismiss the sign-up window and sign up. We also store your device class (phone, tablet or desktop), a coarse source of the visit (search, direct, referral or social) and a hashed network prefix used only to limit abuse. We use no third-party analytics and no advertising trackers.

Purpose: to improve the product and to run the sign-up experiment, an A/B test of how we show free and logged-in features. The identifier is not used for advertising and is not sold or shared.

Retention: the visitor cookie lasts up to 400 days; usage events are kept for 13 months and then deleted. When you create an account from a visit, that visit's events are linked to your account to measure the test; you can ask us to delete them.

Browsers that send Do Not Track are not counted. You can also delete the hk_vid cookie at any time in your browser settings; a new random identifier is set on your next visit.

Your rights

You may ask to access, correct or delete your personal data, to withdraw consent, and to object to processing, as provided by UU PDP.
