Your privacy choices
The Serene app has no ads, analytics or trackers. Only the home page and the ad landing page (serene.day/checkin) of this website use the Meta Pixel, to tell us whether our own Facebook and Instagram ads work.
What it measures
That someone visited one of those pages, and whether they tapped through to the App Store or Google Play. Meta may link that to a Meta account. Nothing from the app, and nothing about how you feel, is ever sent; the feeling you pick on the check-in page stays in your browser. Under some US state laws, such as California's, this can count as "sharing" for advertising, and you can opt out of it here.

Ad measurement is on in this browser.
Your choice is saved in this browser only. If your browser sends Global Privacy Control, we treat that as an opt-out automatically. Questions: support@serene.day.
