Storage locations
Section titled “Storage locations”Daneel uses two browser storage mechanisms:
Chrome Storage (chrome.storage.local)
Section titled “Chrome Storage (chrome.storage.local)”Stores settings, credentials, and lightweight metadata.
| Key | Content |
|---|---|
selectedProvider | Active LLM provider name |
selectedModelId | Active WebGPU model ID |
selectedEmbeddingModelId | Active embedding model ID |
claudeApiKeyEncrypted | AES-256-GCM encrypted Claude API key |
claudeModelId | Selected Claude model |
ollamaBaseUrl | Ollama server URL |
daneel:mcp:servers | Registered MCP server list |
daneel:mcp:disabled | Disabled MCP server IDs |
daneel:mcp:catalog | Cached MCP tool manifests |
daneel:credential:{url} | MCP server credentials |
daneel:agents | Agent definitions |
daneel:docker:config | Docker Companion configuration |
daneel:cloud:azure-sas | Azure Blob Storage SAS URL |
daneel:cloud:s3-config | S3 credentials (JSON) |
| Widget preferences | Theme, color style, position, panel width |
| License data | JWT token, plan tier, feature flags |
| Telemetry preferences | Analytics opt-in/out |
IndexedDB
Section titled “IndexedDB”Stores vector embeddings and large datasets, partitioned by domain or vault.
| Store | Partitioning | Content |
|---|---|---|
embeddings:{hostname} | Per domain | Site page chunks + vector embeddings |
vault:{vaultId} | Per vault | Document chunks + vector embeddings |
| Knowledge graph data | Per vault | Entities, relationships, graph structure |
CacheStorage
Section titled “CacheStorage”Model files downloaded from HuggingFace are cached in the browser’s CacheStorage. These persist across sessions and enable offline use after first download. Daneel uses two separate named caches:
| Cache name | Populated by | Contents |
|---|---|---|
transformers-cache | transformers.js runtime | ONNX shards, tokenizer files, configuration JSON for LLM and embedding models, plus tokenizer files for GLiNER |
daneel-ner-models | NER worker | GLiNER ONNX binaries, fetched directly outside the transformers.js pipeline |
To see how much disk each cached model uses and to reclaim space, see How to Reclaim Disk Space from Local Models.

License
Section titled “License”One-time payment via Stripe. After purchase, you receive a DAN-XXXX-XXXX-XXXX license key. The license is verified via a signed JWT with a 7-day TTL and offline caching — you don’t need to be online continuously.
Data portability
Section titled “Data portability”All data can be exported as a portable .zip file via Settings > Data Backup. Cloud backup to Azure Blob Storage or S3-compatible storage is also available. See How to Back Up Your Data.
Excluded from exports (for security): API keys, cloud storage credentials (SAS URLs, S3 secrets).
