Some things in Celedus work the way they do because we are not allowed to choose otherwise, and some because we chose. This page is both lists. If a feature seems missing or oddly limited, the reason is probably here, and if it is a decision rather than a rule, it is marked as one so you can argue with it.
What the law, or an agreement with another company, requires of us.
We are required to publish both. Privacy law where our users live, and the rules of the services we build on, all say the same thing: if you collect personal data you have to say what you collect, why, and what someone can do about it. That is our Privacy Policy, and the terms you agree to by using the apps are our Terms of Service. We would keep them regardless, but they are not optional, so we hold them to being accurate rather than decorative: when we change what the code does with your data, the policy changes in the same breath.
If you connect Google Calendar, a calendar someone else shared with you can be brought into the planner and used like any other. What you cannot do is service that group to the network: those events come out of the payload, so a share code or calendar feed built from it carries only the items you added yourself.
This is not us being cautious for its own sake. Those events are your friend's data, not yours. They agreed to show them to you, which is a different thing from agreeing to put them on a public link that anyone can open, and Google's API rules do not let us republish data on their behalf either way. Your own calendars have no such limit: those are yours to publish, and servicing a group that mirrors one works normally.
The way around it is the honest one: ask whoever owns the calendar to share it, or use Copy once to take their events as a starting point and make the schedule your own.
Nobody makes us do these. We picked them, and we will tell you why. If you think one is wrong, say so.
Celedus does not read your calendar in the background. Keeping a calendar up to date overnight would mean storing a Google token that can reach your calendar whenever it likes, and holding that key to someone's calendar is a promise we decided not to make for a feature you can get by making the event in the planner instead. So calendars refresh when you sync them, and a reminder covers what is in your planner rather than something you added in Google an hour ago.
If a feature does not work the way you expected and this page does not explain why, that is worth telling us about. Email hello@celedus.app and either the app gets fixed or this page gets another entry.
