Is TickTick - Todo & Task List safe?

Low risk

TickTick - Todo & Task List runs a content script on every page and lets certain page messages close the current tab.

The extension loads one content script on all HTTP and HTTPS pages, while its TickTick and Dida365-specific scripts run only on those service domains. The broad content script listens for page messages and forwards a close-window action to the background worker when it receives a recognized close message, causing the sender tab to be removed.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
