Cartbeat

Privacy Policy

Cartbeat · Last updated October 18, 2026 · info@cartbeat.app

Cartbeat sends basket reminder emails for online shops. Today it runs inside mdrnly: a shop owner turns it on in Settings > Apps, and it works on that shop's checkout. This policy covers this website (cartbeat.app) and the Cartbeat feature.

What Cartbeat uses

Why

We never sell personal data, never build marketing lists from it, and never use one shop's shoppers for another shop.

Who handles it

On mdrnly, shopper and shop data stays in mdrnly and is handled under mdrnly's own terms and privacy policy, which also cover the email delivery. This website is hosted on Fly.io.

How long

Reminder links and codes expire. Basket and reminder records are kept while the shop uses Cartbeat and for a reasonable time after, for the shop's records. Unsubscribes are kept so we keep honoring them.

Your choices

Every reminder has a one-click unsubscribe link and header. To ask what data we hold about you, or to have it deleted, write to the shop you ordered from or to info@cartbeat.app.

Changes

We may update this policy. Changes appear on this page with a new date.
