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 third-party add-ons.
Does it read my whole calendar?+
No. Each add-on only creates and changes its own events. AI Day Planner reads the events of the one day you plan (times and titles) so it can plan around them, and never edits them. Horoscope Calendar Pro also replaces the basic Daily Horoscope event when you upgrade.
Can I remove the events?+
Yes. AI Day Planner has a one-click "Clear plan for this day" button that removes only the events it created. Weather, pollen and horoscope events are ordinary calendar events you can delete like any other, and each add-on updates its own events when it refreshes instead of duplicating them. Uninstalling an add-on stops new events from appearing; events already in your calendar stay until you delete them.
Is there a free trial?+
Weather Calendar is free. Pollen Calendar, Daily Horoscope Calendar, Horoscope Calendar Pro and AI Day Planner include a 7-day free trial with no card: it starts the first time you open the add-on, once per Google account and add-on.
Is it a subscription?+
Paid add-ons are billed yearly via Stripe and you can cancel anytime. Pollen Calendar, Daily Horoscope Calendar, Horoscope Calendar Pro and AI Day Planner keep working for a 14-day grace period if a renewal payment fails; Weather Calendar Pro and Ultra end at the end of the paid year if the renewal has not gone through.
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 say so up front. The readings are for entertainment only, not advice of any kind.
How do I get support?+
Email work@louissch.com. A real person, usually the developer, answers.
