 # Privacy Policy
 
-TidGi respects your privacy and does not track or log anything from you.
+TidGi respects your privacy and is designed with privacy as a core principle.
 
-Still, the app does use third party services that may collect information used to identify you.
+## Data Collection
 
-- G Suite for email and business tools.
-- GitHub for distributing the software.
+TidGi stores your notes and workspace data on your device and in your chosen storage locations (local folders or your own Git repositories). Anonymous product analytics are enabled by default when configured, but they are limited to coarse application behavior and never include your content.
 
-This privacy policy is subject to change without notice and was last updated on 2021-02-27. If you have any questions feel free to create a GitHub issue.
+### Optional Anonymous Usage Analytics
+
+TidGi offers anonymous usage analytics to help improve the application. This feature is:
+
+- **Enabled by default when configured** - TidGi shows a first-run disclosure and offers an immediate off switch
+- **Anonymous** - No personal information, user content, workspace names, file paths, or identifiable data is collected
+- **Coarse-grained** - Only high-level events like app launches, settings opens, sync outcomes, updater checks, and feature usage are tracked
+- **Configurable** - You can point TidGi to your own self-hosted Rybbit instance
+- **Transparent** - All tracked events are limited to application behavior, never your notes or personal content
+
+When enabled, analytics may collect:
+- Application launch events
+- Workspace creation and activation (without names or paths)
+- Preference changes related to analytics configuration
+- Settings window opens, theme changes, deep-link opens, sync outcomes, and updater checks
+- Platform and version information
+
+Analytics **never** collect:
+- Note content or titles
+- Workspace names or file paths
+- URLs or web browsing history
+- Authentication tokens or API keys
+- Any personally identifiable information (PII)
+
+You can disable analytics at first launch or at any time in Preferences > Privacy & Security.
+
+## Third-Party Services
+
+The app may use third-party services that could collect information:
+
+- **G Suite** - For email and business tools (developer communication only)
+- **GitHub** - For distributing the software and hosting public repositories
+- **Your chosen Git provider** - If you configure TidGi to sync with GitHub, GitLab, Gitee, or other Git services, your data is transmitted according to your configuration and that provider's privacy policy
+
+## Your Control
+
+You have full control over your data:
+- All notes and content are stored locally or in your own Git repositories
+- You choose which Git service (if any) to use for synchronization
+- You can export your data at any time
+- Analytics can be disabled at any time
+
+## Changes to This Policy
+
+This privacy policy is subject to change without notice and was last updated on 2026-04-29.

+# Analytics in TidGi Desktop
+
+This document explains how analytics works in TidGi Desktop, what is intentionally tracked, what is intentionally blocked, and how plugin authors should integrate with the analytics service.
+
+## Goals
+
+TidGi uses analytics to understand coarse product usage without collecting user content.
+
+The current design goals are:
+
+- Keep all network delivery in the Electron main process
+- Never expose the analytics API key to renderer or plugin code
+- Track only coarse, product-level behavior
+- Reject free-form content, note text, file paths, URLs, tokens, and other sensitive payloads
+- Give plugin authors a stable way to emit custom product events without bypassing privacy guardrails
+
+## Architecture
+
+1. Renderer code and TiddlyWiki plugins call the TidGi analytics service through the existing IPC proxy layer
+2. The analytics service runs in the main process
+3. The main process sends events to Rybbit over HTTP
+
+## Delivery model
+
+- Analytics is enabled only when all of the following are true:
+  - `analyticsEnabled` preference is `true`
+  - `analyticsHost` is configured
+  - `analyticsSiteId` is configured
+  - a main-process-only analytics API key is configured
+- Unsent events may be queued temporarily in memory
+- The queue is dropped immediately when the user disables analytics
+- The first-run disclosure is tracked separately from normal product events
+
+## Privacy constraints
+
+TidGi analytics must never contain:
+
+- note titles or note bodies
+- workspace names
+- filesystem paths
+- raw URLs
+- access tokens, OAuth codes, cookies, or API keys
+- free-form user text copied from the UI
+
+If a proposed event depends on any of the above, do not add it to analytics.
+
+## Built-in events
+
+The application currently emits built-in events such as:
+
+- `app.launched`
+- `analytics.disclosure_dismissed`
+- `workspace.created`
+- `workspace.activated`
+- `preferences.analytics_updated`
+- `settings.opened`
+- `theme.changed`
+- `deep_link.opened`
+- `sync.triggered`
+- `sync.completed`
+- `sync.failed`
+- `updater.check_started`
+- `updater.update_available`
+- `updater.update_not_available`
+- `updater.check_failed`
+- `error.report_requested`
+
+Built-in events use an allowlist. For each built-in event, only explicitly approved property keys are retained.
+
+That allowlist lives in `src/services/analytics/index.ts`.
+
+## Plugin-defined custom events
+
+Plugin authors must not emit arbitrary event names through the low-level built-in event contract.
+
+Instead, plugins should call:
+
+```ts
+await window.service.analytics.trackPluginEvent(pluginId, eventName, properties);
+```
+
+or inside a TiddlyWiki plugin:
+
+```ts
+await $tw.tidgi.service.analytics.trackPluginEvent(pluginId, eventName, properties);
+```
+
+### Final event name format
+
+The service converts plugin calls into this final event name:
+
+```text
+plugin.<pluginId>.<eventName>
+```
+
+Example:
+
+```ts
+await window.service.analytics.trackPluginEvent('kanban-board', 'card_created', {
+  source: 'toolbar',
+  has_due_date: true,
+});
+```
+
+Emits:
+
+```text
+plugin.kanban-board.card_created
+```
+
+### Validation rules
+
+Plugin event names are intentionally restricted.
+
+- `pluginId` must match: `^[a-z0-9]+(?:[-_][a-z0-9]+)*$`
+- `eventName` must match: `^[a-z0-9]+(?:[-_][a-z0-9]+)*$`
+- Property keys must match: `^[a-z][a-z0-9_]{0,39}$`
+- Property values must be `string | number | boolean`
+- String values are truncated to 120 characters
+
+If `pluginId` or `eventName` is invalid, the event is rejected.
+
+If all properties are invalid, the event is still allowed to be sent without properties.

+## Usage for analytics
+
+TidGi exposes `analytics` to both renderer code and TiddlyWiki plugins.
+
+Use the guarded plugin-facing method for custom analytics:
+
+```ts
+await window.service.analytics.trackPluginEvent('my-plugin', 'panel_opened', {
+  source: 'toolbar',
+  has_selection: true,
+});
+```
+
+Inside a TiddlyWiki plugin module:

+const tidgiService = ($tw as typeof $tw & { tidgi?: { service?: ITidGiGlobalService } }).tidgi?.service;
+
+await tidgiService?.analytics.trackPluginEvent('my-plugin', 'panel_opened', {
+  source: 'toolbar',
+  has_selection: true,
+});
+```
+
+The final emitted event name becomes:
+
+```text
+plugin.my-plugin.panel_opened
+```
+
+### Analytics guardrails
+
+- `pluginId` and `eventName` must be lowercase slug-like identifiers
+- Property keys must be short snake_case-style identifiers
+- Property values must be `string | number | boolean`
+- Do not send note text, tiddler titles, workspace names, file paths, tokens, or raw URLs
+
+See [Analytics.md](./Analytics.md) for the full analytics contract.

+# Workspace Grouping
+
+## Overview
+
+Workspace grouping lets users organize multiple wiki workspaces into named collections in the left sidebar.
+
+A group behaves like a lightweight container:
+
+- it has a name
+- it can be collapsed and expanded
+- it can be reordered with other groups and ungrouped workspaces
+- workspaces can be added to it, moved between groups, or dragged back out
+
+This feature is designed to keep the sidebar manageable when a user has many workspaces, while still preserving direct drag-and-drop interaction.
+
+## User-facing behavior
+
+### Create a group by dragging
+
+The most direct way to create a group is to drag one ungrouped workspace onto another ungrouped workspace.
+
+When the pointer is in the center zone of the target workspace, TidGi interprets the action as a grouping action instead of a reorder action. A new group is created and both workspaces become members of that group.
+
+### Reorder without grouping
+
+Dragging near the top or bottom area of a workspace means reorder, not group.
+
+- top area means place before
+- bottom area means place after
+- center area means group, if grouping is allowed for that pair
+
+This is how the same drag gesture supports both list ordering and grouping without introducing separate drag handles or extra modes.
+
+### Move workspaces into an existing group
+
+An ungrouped workspace can be dragged onto a workspace that already belongs to a group.
+
+If the pointer lands in the center grouping zone, the dragged workspace joins the target workspace's group.
+
+If the pointer lands in a reorder zone, the workspace stays ungrouped and is only repositioned in the sidebar order.
+
+### Move workspaces between groups
+
+A workspace that already belongs to one group can be dragged onto a workspace in another group.
+
+If the drop intent resolves to grouping, TidGi moves the dragged workspace into the target group.
+
+### Remove a workspace from a group
+
+Dragging a grouped workspace onto the header of its own group means ungroup.
+
+This is an intentional shortcut. Users do not need a separate command just to pull one workspace back out into the ungrouped area.
+
+### Reorder groups
+
+Groups also participate in sidebar ordering.
+
+A group header can be dragged:
+
+- before another group
+- before an ungrouped workspace
+
+This allows the sidebar to behave as one mixed ordering space rather than as two separate lists.
+
+### Collapse and expand groups
+
+Each group header can be collapsed to hide its member workspaces and expanded again later.
+
+Collapsing only changes presentation. It does not remove workspaces from the group and does not change group membership.
+
+## Preferences-based management
+
+In addition to drag-and-drop, groups can also be managed from Preferences.
+
+The Preferences view provides a management section where users can:
+
+- create a new named group
+- rename an existing group
+- delete a group
+- assign or remove workspaces through a selection control
+
+This path is useful when a user wants precise group management without dragging items in the sidebar.
+
+## Interaction model
+
+### Sidebar ordering model
+
+TidGi treats the sidebar as an interleaved sequence of two item types:
+
+- ungrouped workspaces
+- group headers
+
+Grouped workspaces are rendered under their group header, but the ordering logic still treats the sidebar as one ordered structure. This is why a group can be placed before another group or before an ungrouped workspace.
+
+## Developer
+
+### Why the ghost preview was removed
+
+Earlier versions (before v0.13.1) used a ghost or placeholder style preview that visually moved items around while dragging. In theory this made the future drop position easier to imagine. In practice it introduced a more serious problem: the DOM and drop zones moved during the drag itself.
+
+That movement caused two kinds of trouble.
+
+First, intent detection became less reliable. The pointer could start over one target, the placeholder would shift the layout, and the actual drop zone under the pointer would no longer match what the user thought they were aiming at. This was especially problematic when deciding between:
+
+- reorder before
+- reorder after
+- create or join a group
+
+Second, tests and real usage could both observe unstable target geometry. Drag-and-drop logic depends on measuring current rectangles and collisions. When the list visually reorders in the middle of the gesture, those rectangles can change under the pointer and make the result harder to predict.
+
+Because of that, TidGi now keeps DOM positions stable during the drag.
+
+The current approach is:
+
+- keep the canonical sidebar layout in place while dragging
+- do not insert a moving ghost placeholder into the list
+- show drag intent through highlighting instead
+
+The highlight still tells the user what will happen:
+
+- grouping intent
+- ungrouping intent
+- reorder before
+- reorder after
+
+This trades a more dramatic preview for a more trustworthy interaction. The result is easier to reason about, easier to test, and less likely to produce accidental grouping or accidental reordering.

+Feature: Workspace Grouping
+  As a user with multiple workspaces
+  I want to organize them into groups
+  So that I can manage them more efficiently
+
+  Background:
+    Given I cleanup test wiki so it could create a new one on start
+    When I launch the TidGi application
+    And I wait for the page to load completely
+    And the browser view should be loaded and visible
+
+  Scenario: Ungrouping workspaces and emptying groups via own-group-header drag
+    When I create new wiki workspaces with names:
+      | Ungroup Alpha |
+      | Ungroup Beta  |
+      | Ungroup Gamma |
+    Given workspace group "Group Dual" contains workspaces:
+      | Ungroup Alpha |
+      | Ungroup Beta  |
+    Given workspace group "Group Solo" contains workspaces:
+      | Ungroup Gamma |
+    # Test: removing from multi-item group leaves the other item grouped
+    When I drag workspace "Ungroup Alpha" onto the header of its current group
+    Then workspace "Ungroup Alpha" should be ungrouped
+    And workspace "Ungroup Beta" should be in a group
+    # Test: removing the last workspace deletes the empty group
+    When I drag workspace "Ungroup Gamma" onto the header of its current group
+    Then workspace "Ungroup Gamma" should be ungrouped
+    And there should be 1 workspace groups
+
+  Scenario: Dragging across top, bottom, and center zones covers grouped and ungrouped targets
+    When I create new wiki workspaces with names:
+      | Zone Test Alpha |
+      | Zone Test Beta  |
+      | Zone Test Gamma |
+      | Zone Test Delta |
+    When I drag workspace "Zone Test Gamma" to the top zone of workspace "Zone Test Alpha"
+    And workspace "Zone Test Gamma" should appear before workspace "Zone Test Alpha"
+    When I drag workspace "Zone Test Gamma" to the bottom zone of workspace "Zone Test Beta"
+    Then workspace "Zone Test Gamma" should appear after workspace "Zone Test Beta"
+    When I drag workspace "Zone Test Alpha" onto workspace "Zone Test Beta"
+    Then workspaces "Zone Test Alpha" and "Zone Test Beta" should share a group
+    When I drag workspace "Zone Test Delta" to the top zone of workspace "Zone Test Alpha"
+    Then workspace "Zone Test Delta" should appear before workspace "Zone Test Alpha"
+    And workspaces "Zone Test Alpha" and "Zone Test Beta" should share a group
+    When I hover workspace "Zone Test Delta" over workspace "Zone Test Beta"
+    Then workspace "Zone Test Beta" should show "group" drag intent
+    And I press "Escape" key
+    Then workspace "Zone Test Delta" should be ungrouped
+    And workspaces "Zone Test Alpha" and "Zone Test Beta" should share a group
+
+  Scenario: Dragging workspace between different groups after collapsing and re-expanding the source group
+    When I create new wiki workspaces with names:
+      | Cross Group Alpha |
+      | Cross Group Beta  |
+      | Cross Group Gamma |
+    Given workspace group "Cross Group A" contains workspaces:
+      | Cross Group Alpha |
+      | Cross Group Beta  |
+    Given workspace group "Cross Group B" contains workspaces:
+      | Cross Group Gamma |
+    When I collapse workspace group "Cross Group A"
+    And I expand workspace group "Cross Group A"
+    And I drag workspace "Cross Group Alpha" onto workspace "Cross Group Gamma"
+    Then workspaces "Cross Group Alpha" and "Cross Group Gamma" should share a group
+    And workspace "Cross Group Beta" should be in a group
+
+  Scenario: Reordering group headers and positioning before ungrouped workspaces
+    When I create new wiki workspaces with names:
+      | Group Order Alpha |
+      | Group Order Beta  |
+      | Group Order Gamma |
+    Given workspace group "Group Order A" contains workspaces:
+      | Group Order Alpha |
+    Given workspace group "Group Order B" contains workspaces:
+      | Group Order Beta |
+    When I drag group header "Group Order B" onto group header "Group Order A"
+    Then group "Group Order B" should appear before group "Group Order A"
+    When I drag group header "Group Order A" onto workspace "Group Order Gamma"
+    Then group "Group Order A" should appear before workspace "Group Order Gamma"
