Fields

theme: AppTheme

thumbnail_size: u32

face_detection_confidence: f32

face_clustering_threshold: f32

burst_time_window_seconds: i64

trash_auto_delete_days: u32

scan_hidden_folders: bool

show_timeline_stacks: bool

date_format: DateFormat

remembered_drives: Vec<PathBuf>

window_width: u32

window_height: u32

window_maximized: bool

Whether the user’s window was maximised when they last closed the app. Restored at startup by the Tauri shell.

sidebar_collapsed: bool

map_cache_limit_mb: u32

weight_cooccurrence: f32

Weight applied to co-occurrence prior when multiple candidate clusters exist for an unassigned face. 0 disables the signal.

weight_temporal: f32

Weight applied to temporal-neighbor prior (±60 s, same cluster).

memories_enabled: bool

Whether the Memories feature (N years ago today, seasonal recaps) is on.

home_city_override: Option<String>

Optional user-specified home city for album suggestions. When set, the suggestion engine skips auto-detection of the home city.

last_view: Option<String>

Last-viewed top-level view; restored on app launch. Stored as a string for forward compatibility across View enum changes.

auto_update_check_enabled: bool

Opt-in: whether Smriti should query GitHub Releases once every 24 hours to see if a new version is available. Off by default — the first-run prompt flips it on if the user agrees. See PRIVACY.md.

last_update_check_at_unix: Option<i64>

Unix timestamp of the last update check. Used to rate-limit the background subscription to at most one check per 24 h.

show_first_run_update_prompt: bool

True until the user accepts or declines the first-run update prompt. After that, toggling is done through Settings.

date_logic_version: u32

Version of the EXIF date-extraction logic the user’s library was last evaluated against. When the binary’s CURRENT_DATE_LOGIC_VERSION is higher, the app auto-runs RefreshPhotoDates once on first launch with the upgraded binary so users don’t keep seeing 2012 ghosts on photos shot in 2026 etc. After the refresh runs, this field is bumped to the new version.

geonames_warning_seen: bool

True once the user has been shown the “Place names off — run scripts/setup_assets.sh” toast. Prevents the same toast appearing on every drive-select.

thumbnail_cache_gb: f64

Disk budget for the on-drive thumbnail cache, expressed in gigabytes. Drives the LRU eviction in ThumbnailService. Default 5 GB suits a mid-size phone library; small-disk users can dial down, big-library users up.

face_gpu_bridge_url: Option<String>

Optional GPU bridge URL for face embedding (opt-in).

face_gpu_bridge_enabled: bool

Whether the GPU bridge is explicitly enabled by the user.

config_version: u32

Version of config migrations applied. Bumped each time a default changes and existing installs need a one-time pick-up.

face_embedder_model: String

Face embedding model filename (relative to the models directory). AdaFace is the only supported local recognizer.

assistant_enabled: bool

Enables the album-only in-app Assistant. Semantic search remains available when this is off.

ai_features_enabled: bool

Top-level opt-in for provider-backed AI features. Local semantic search is not gated by this.

assistant_provider: String

Assistant provider identifier. local keeps the deterministic album-only harness; openai_compatible enables the saved endpoint configuration for a provider-backed assistant turn.

assistant_base_url: String

OpenAI-compatible chat completions base URL.

assistant_model: String

Provider model name.

assistant_api_key: Option<String>

Provider API key. DTOs only expose whether this is set.
