Logo
A logo hides part of the code, so error correction is raised and the size is limited to what the code can safely repair.
Error correction
A phone can still read a code that is partly damaged: scratched, dirty or covered by a logo. This level sets how much damage it can recover from. A higher level gives more reserve, but the code gets denser, with smaller squares, and holds less data.
Most people should leave Automatic: it picks M, or H with a logo, and lowers the level if the data does not fit. Choose Q or H for codes outdoors or on packaging that can get damaged, and L or M for long text or very small print. With a logo the level is never below Q.

For posters and invitations
Print it on a poster or invitation so that people save the date on the spot. All details are inside the code, so there is no event page to host. Keep the text short to keep the code easy to scan.
A note on time zones
The time is stored as local time with no time zone, and calendars show it as entered. For online events with guests in other countries, write the time zone in the details.
Questions
Does this work on all phones?
Apple has documented calendar codes for the iPhone camera, but we found no such official statement for Android. Test the code on an iPhone and an Android phone before printing a lot.
Will this QR code ever expire?
No. There is nothing that can expire: the code contains your data itself and works without any server. It keeps working as long as it can be scanned and, for a link, as long as that website exists.
Is it really free? Are there limits on scans?
Yes, it is free with no account. Scans are unlimited because nobody counts them: a scan happens entirely between the code and the phone. The site is paid for by advertising.
Do you see my data or logo?
No. The code is created in your browser and nothing is uploaded. You can load the page, go offline, and it keeps working.
Will it scan on every phone?
Every code is read back by a decoder in your browser before download, and you get a warning if that fails. That is a software check, so scan one printed copy with your own phone before a large print run.
