On the free plan, and while Starter is free with your own key, the to-do list shows sponsored cards, marked "Sponsored · …":
- no card while a day has fewer than four notes,
- one card with four notes,
- two cards (top and bottom, from different sponsors) with more.
They look different from your notes and never mix with them. Tapping one opens the sponsor's page in your browser.
Privacy: to choose a card, the app sends only its language and your country, no identifier. Nothing about your notes is used.
Paid plans (Starter, Pro and Max) have no sponsored cards.
