Questions
Does it work on mobile?+
Yes. Install once from a desktop computer; the events then show up in Google Calendar on your phone and tablet too.
Which Google accounts are supported?+
Personal Gmail accounts and Google Workspace accounts, as long as your admin allows Marketplace add-ons.
Does it read my whole calendar?+
No. Each add-on only creates and updates its own events. The AI Day Planner looks at your busy times so it can plan around them.
Can I remove the events?+
Yes. Every add-on has a one-click clear option, and uninstalling removes future events.
Is it a subscription?+
Paid add-ons are billed yearly via Stripe. You can cancel anytime, and there is a 14-day grace period if a renewal fails.
Which countries does Pollen Calendar cover?+
More than 65 countries, using Google Pollen API data. It is an informational tool, not medical advice.
Are the horoscopes written by AI?+
Yes. Both horoscope add-ons use AI-generated readings, and we label them that way.
How do I get support?+
Email work@louissch.com. A real person, usually the developer, answers.
