Why Calendar Feeds Break (And How We Fix Them)
RFC 5545 Compliance Engine
We handle the ugly details: 75-octet line folding, CRLF endings, and VTIMEZONE injections. Your feeds work correctly on every device.
- Automated Line Folding
- Timezone Definition Injection
Stop Sync Cycle Failures
Infinite recursion loops and UID Collisions do not just break calendars. They cause "flickering" events that kill mobile batteries.
- Recursion Depth Limiting
- Unique UID Enforcement
Eliminate Support Debt
Your users do not care about ICS standards. We repair broken feeds in real time, so you never see a Calendar Not Syncing ticket again.
- Zero Config Proxy
- Zero Persistence Architecture
- Self Healing Infrastructure

Built for Security and Compliance
We process calendar data in memory and immediately discard it. No permanent storage. No data retention. Zero persistence architecture.
Zero Persistence
Calendar events are processed in real time and never written to disk. We act as a stateless proxy.
SOC 2 Type II
Independently audited security controls. Annual penetration testing and continuous monitoring.
GDPR & HIPAA Ready
Data Processing Agreements available. BAA execution for healthcare customers. EU data residency options.
How It Works
No database migrations. No code to write. Just a smarter URL.
Source Feed
We fetch your existing calendar feed (ICS) from Banner, PeopleSoft, or any URL.
The Lokr Proxy
We detect and repair 36+ RFC 5545 violations in real-time: missing VTIMEZONEs, broken RRULEs, invalid UIDs, stale DTSTAMPs, and more.
Perfect Sync
Students and staff subscribe to the new Lokr link. It works on every device, instantly.
Trusted by Engineering Teams
We don't sell to end-users. We build for the engineers and admins who have to keep the systems running.

Sarah J.
Registrar IT Manager, State University

Mark D.
LMS Admin, Private College
"I spent weeks debugging VTIMEZONE issues on Android. Pointed our feeds to Lokr on Friday, and the errors were gone by Monday."
