MailZyro Slides
BetaEncrypted slides for team decks.
A presentation app for private, collaborative work. Build, import, present and edit together while your deck data stays end-to-end encrypted at rest.
Why Slides
Built for private presentations.
Private by design
Each deck has its own key wrapped per user — even speaker notes stay unreadable to us.
Made for teamwork
Live cursors and threaded comments anchored to a slide or element.
Ready for real decks
Templates, PPTX and Google Slides import, and export. Core is here — in Beta.
How privacy works
Your deck stays unreadable to us.
Slides uses the same proven encryption stack as MailZyro Sheets, adapted for presentations.
Deck key
Every presentation gets its own AES-256 key.
User wrapping
That deck key is wrapped with each collaborator’s OpenPGP key.
Worker isolation
Crypto runs in an isolated Web Worker, away from the main app thread.
Auto-unlock
Single sign-on unlocks your access without exposing readable deck data to our servers.
For the technically curious: AES-256-GCM with OpenPGP per-user key wrapping, crypto isolated in a Web Worker.
Work together
Edit together without losing context.
Live cursors
See where teammates are working in the deck as changes happen. It keeps shared editing calm and easier to follow.
Threaded comments
Start a thread on a slide or a specific element. Reply, resolve and reopen comments as the deck moves forward.
Version history
Earlier versions are saved so the team can recover from mistakes. Restore a prior version when a direction does not work out.

The basics are already deep.

Core editing, collaboration, encryption, import, export and presenting are solid enough to use today. It is still Beta, so some surrounding features are still coming — use it with that expectation.
