iCloud Storage & Privacy
FeynmanLM stores your data in your personal iCloud container. Your sources and knowledge base sync automatically via iCloud, without ever touching FeynmanLM servers.
How it works
All data is written to your private iCloud container — a dedicated, app-specific storage area within your iCloud account. Apple handles sync and encryption:
- At rest: encrypted on Apple's servers with keys derived from your iCloud account.
- In transit: encrypted over TLS between your devices and iCloud.
- On device: protected by your device passcode and the Secure Enclave.
No FeynmanLM server ever sees or stores your content.
What's stored in iCloud
| Data | Description |
|---|---|
| Knowledge database | Sources and their content |
| Source PDFs | Papers, books, and articles you've added |
| Artifacts | Generated explorable explanations and Feynman session records |
Data is stored as flat files and a SQLite database, so sync is fast and reliable.
What FeynmanLM servers never see
- Your source content
- Your book or article PDFs
- Your podcast transcripts
- Your Feynman session history
The only network calls FeynmanLM makes are to AI providers (for embeddings) and via the MCP server (which runs locally on your Mac). The MCP tunnel exposes your local server but all data stays on your machine.
Deleting your data
Since everything is in your iCloud account, you have full control:
- Delete the app: removes local data from that device. iCloud data remains until you remove it.
- Delete from iCloud: go to Settings > [Your Name] > iCloud > Manage Storage > FeynmanLM and delete the data.
No need to contact FeynmanLM or request data deletion. You own it all.
