Native "Free/Busy" Website Embed (Bypassing Google)
Dear Proton Team,
I am a dedicated Proton user relying on your services for privacy. However, I am facing a major hurdle in using Proton Calendar for my business workflow.
The Problem: I need to display my availability to clients on my website (e.g., Wix, WordPress). Currently, there is no native way to do this. The only workaround is sharing an ICS link to Google Calendar and embedding that. This fails for two reasons:
Sync Latency: Google updates subscribed calendars very slowly (up to 24 hours delay), leading to double bookings.
Permission Conflicts: Google treats subscribed Proton calendars as "read-only" and blocks the public embedding of these "guest" calendars due to privacy settings I cannot change.
The Request: Please introduce a Native Public Embed Feature.
Function: Generate a secure HTML iframe code directly within Proton Calendar.
Privacy: This view should strictly show "Free/Busy" status, stripping all titles, descriptions, and locations server-side before rendering.
Benefit: This would allow professionals to display real-time availability on their websites while keeping their data within the Proton ecosystem, removing the need for Google entirely.
This feature would be a game-changer for freelancers and consultants who prioritize privacy.
Thank you for considering this!

I completely agree, this is a real limitation right now. Since Proton Calendar relies on shared links and ICS subscriptions, delays can happen because external calendars may only sync every several hours, sometimes even up to 16 hours depending on the provider . That makes it unreliable for real-time availability and definitely increases the risk of double bookings.
A native embed feature showing only free/busy status would solve this cleanly while preserving privacy. It would remove the dependency on Google and make Proton much more practical for business use cases.
For example, professionals who manage bookings through their website like https://powerwashinglv.us would benefit a lot from a secure, real-time availability embed directly from Proton.
