For a full step-by-step guide, see INSTALLATION.md.

Prerequisites

• Docker (20.10+) and Docker Compose (2.0+)
• 2GB+ RAM available for Docker containers
• Port 8080 (HTTP) or 80/443 (HTTPS production)

New to Docker? See Docker Installation Guide for your platform.

Option 1: NAS / one-file compose (recommended for first try)

Same stack as Quick start. Paste docker-compose.nas.yml into Container Station, Synology Container Manager, or Portainer; set SECRET_KEY; open http://:8080.

Works on QNAP, Synology, Unraid/Portainer, and other Docker-capable NAS devices (amd64 and arm64).

Full guide: NAS Deployment Guide

Option 2: Production with HTTPS

Clone the repo and use the root compose file (nginx + self-signed cert):

git clone https://github.com/drytrix/TimeTracker.git
cd TimeTracker
cp env.example .env
# Set a strong SECRET_KEY, TZ, and CURRENCY in .env
docker compose up -d
# Access at https://localhost — accept the self-signed certificate warning

First login creates the admin account. For setup problems, see INSTALLATION.md.

Default install (no bundled AI): the main docker-compose.yml starts the app and PostgreSQL only. Optional Ollama: see AI Helper.

Complete setup guide: docs/admin/configuration/DOCKER_COMPOSE_SETUP.md · Uninstall: UNINSTALL.md

Troubleshooting: Docker Startup · CSRF · Database

Option 3: Docker with plain HTTP (development)

🐳 Deployment

Local Development

# Start with HTTPS (recommended)
docker-compose up -d

# Or use plain HTTP for development
docker-compose -f docker-compose.example.yml up -d

Production Deployment

Option 1: Build from Source

# Clone the repository
git clone https://github.com/drytrix/TimeTracker.git
cd TimeTracker

# Configure your .env file
cp env.example .env
# Edit .env with production settings:
# - Set a strong SECRET_KEY: python -c "import secrets; print(secrets.token_hex(32))"
# - Configure TZ (timezone) and CURRENCY
# - Set PostgreSQL credentials (POSTGRES_PASSWORD, etc.)

# Start the application
docker-compose up -d

Option 2: Use Pre-built Images

# Use the remote compose file with published images
docker-compose -f docker/docker-compose.remote.yml up -d

⚠️ Security Note: Always set a unique SECRET_KEY in production! See CSRF Configuration for details.

AI Helper (Ollama or hosted)

TimeTracker includes an optional server-side AI helper for the web app and API clients. New installs default to AI off (AI_ENABLED=false in env.example and in the root docker-compose.yml app service) so time tracking works without downloading a large language model.

• Enable (any setup): set AI_ENABLED=true (environment or Admin → System Settings → AI Helper).
• Ollama: set AI_PROVIDER=ollama, AI_MODEL=..., and AI_BASE_URL to http://ollama:11434 when Ollama runs in Docker on the same Compose network, or http://127.0.0.1:11434 when Ollama runs on the host.
• Hosted OpenAI-compatible: set AI_PROVIDER=openai_compatible and AI_API_KEY=...

The AI helper is exposed as:

• Session web UI JSON: POST /api/ai/chat (same-origin, login required)
• REST API v1: POST /api/v1/ai/chat (API token required, scopes read:ai/write:ai)

Time entry suggestions (when AI_ENABLED=true):

• GET /api/ai/suggest — deterministic suggestions from recent patterns and active tasks; optional ?q= filters by notes/project name; ?rich=true merges LLM suggestions when configured. AI failures return deterministic results only.
• Start Timer modal: horizontal suggestion chips above the project field (refresh for LLM-enhanced suggestions).
• Log Time form: “✦ Autofill” popover and ghost-text autocomplete on the notes field (app/static/js/ai_autocomplete.js).

All suggestion UI is hidden when AI is disabled (ai_enabled in template context).

Bundled Ollama service (Docker Compose, opt-in)

The root docker-compose.yml defines a CPU-only ollama service and a one-shot ollama-init sidecar that pulls AI_MODEL (default llama3.1, ~4.7 GB) into the ollama_data volume. These services use the Compose ai profile so they do not start by default.

Enable bundled Ollama:

1. In .env, set AI_ENABLED=true, AI_PROVIDER=ollama, AI_BASE_URL=http://ollama:11434, and your desired AI_MODEL.

2. Start the stack with the profile:

   docker compose --profile ai up -d
   

• The app reaches Ollama at http://ollama:11434 over the Docker network — no host ports need to be opened.
• Change the model by setting AI_MODEL in .env (e.g. AI_MODEL=qwen2.5:3b for lighter hardware) and re-running docker compose --profile ai up -d; the init sidecar will pull the new model when needed.
• Pulled models are cached in the ollama_data named volume, so subsequent boots are faster.
• Verify in the UI: Admin → System Settings → AI helper, then click Test connection.
• To pull additional models manually: docker compose exec ollama ollama pull (with the ai profile active).
• Hosted provider only (no Ollama containers): set AI_PROVIDER=openai_compatible, AI_BASE_URL, and AI_API_KEY in .env; keep docker compose up -d without the ai profile.

Disable or remove AI (turn off LLM calls, stop Ollama, revoke tokens, delete ollama_data safely): UNINSTALL.md.

Encrypting stored secrets (recommended)

To store sensitive settings (OAuth secrets, mail password, AI API key, Peppol token, 2FA secret) encrypted at rest, set:

• SETTINGS_ENCRYPTION_KEY (Fernet key), or
• SETTINGS_ENCRYPTION_KEY_FILE (file path with the key on the first line)

Raspberry Pi Deployment

TimeTracker runs perfectly on Raspberry Pi 4 (2GB+ RAM):

# Same Docker commands work on ARM architecture
docker-compose up -d

HTTPS Configuration

Automatic HTTPS (Easiest)

# Uses self-signed certificates (generated automatically)
docker-compose up -d
# Access at https://localhost (accept browser warning)

Manual HTTPS with mkcert (No Browser Warnings)

# Use mkcert for locally-trusted certificates
docker-compose -f docker/docker-compose.https-mkcert.yml up -d

📖 See HTTPS Setup Guide for detailed instructions. HTTPS helper scripts live in scripts/ (e.g. from project root: bash scripts/setup-https-mkcert.sh, bash scripts/start-https.sh).

Monitoring & Analytics

# Alternate compose files (local-test, remote, analytics, https) are in docker/; use -f docker/docker-compose.xxx.yml

# Deploy with full monitoring stack (Prometheus, Grafana, Loki)
docker-compose -f docker-compose.yml -f docker/docker-compose.analytics.yml --profile monitoring up -d
# Grafana: http://localhost:3000
# Prometheus: http://localhost:9090

📖 See Deployment Guide for detailed instructions
📖 See Docker Compose Setup for configuration options

🔧 Configuration

TimeTracker is highly configurable through environment variables. For a comprehensive list and recommended values, see:

• docs/admin/configuration/DOCKER_COMPOSE_SETUP.md
• env.example

Common settings:

# Timezone and locale
TZ=America/New_York
CURRENCY=USD

# Timer behavior
SINGLE_ACTIVE_TIMER=true
IDLE_TIMEOUT_MINUTES=30
ROUNDING_MINUTES=1

# User management
# Note: Only the first username in ADMIN_USERNAMES is auto-created during initialization.
# Additional usernames must self-register (if ALLOW_SELF_REGISTER=true) or be created manually.
ADMIN_USERNAMES=admin,manager
ALLOW_SELF_REGISTER=false

# Security (production)
SECRET_KEY=your-secure-random-key
SESSION_COOKIE_SECURE=true

📊 Analytics & Telemetry

TimeTracker includes optional analytics and monitoring features to help improve the application and understand how it's being used. All analytics features are:

• ✅ Disabled by default — You must explicitly opt-in
• ✅ Privacy-first — No personally identifiable information (PII) is collected
• ✅ Self-hostable — Run your own analytics infrastructure
• ✅ Transparent — All data collection is documented

What We Collect (When Enabled)

1. Structured Logs (Always On, Local Only)

• Request logs and error messages stored locally in logs/app.jsonl
• Used for troubleshooting and debugging
• Never leaves your server

2. Prometheus Metrics (Always On, Self-Hosted)

• Request counts, latency, and performance metrics
• Exposed at /metrics endpoint for your Prometheus server
• Stays on your infrastructure

3. Error Monitoring (Optional - Sentry)

• Captures uncaught exceptions and performance issues
• Helps identify and fix bugs quickly
• Opt-in: Set SENTRY_DSN environment variable

4. Product Analytics (Optional - Grafana OTLP)

• Tracks feature usage and user behavior patterns with advanced features:
  • Person Properties: Role, auth method, login history
  • Group Analytics: Segment by version, platform, deployment
  • Rich Context: Browser, device, environment on every event
• Sink config: Set GRAFANA_OTLP_ENDPOINT and GRAFANA_OTLP_TOKEN

Rollouts and kill switches in this application are not driven by remote PostHog feature flags. Use environment variables and app/config.py (for example DEMO_MODE, ALLOW_SELF_REGISTER, ENABLE_TELEMETRY, SINGLE_ACTIVE_TIMER). Per-user UI visibility preferences are stored on the user record in the database, not in PostHog. With DEMO_MODE, the auto-created login is a standard user (no admin or settings access); see docs/deploy/RENDER.md for demo setup and upgrading old demo databases.

5. Installation Telemetry (Optional, Anonymous)

• Sends anonymous installation data via Grafana OTLP with:
  • Anonymized fingerprint (SHA-256 hash, cannot be reversed)
  • Application version
  • Platform information
• No PII: No IP addresses, usernames, or business data
• Opt-in: Set ENABLE_TELEMETRY=true for detailed analytics; base telemetry remains anonymous

How to Enable Analytics

# Enable Sentry error monitoring (optional)
SENTRY_DSN=https://your-sentry-dsn@sentry.io/project-id
SENTRY_TRACES_RATE=0.1  # 10% sampling for performance traces

# Configure Grafana Cloud OTLP sink (optional)
GRAFANA_OTLP_ENDPOINT=https://otlp-gateway-prod-eu-west-2.grafana.net/otlp/v1/logs
GRAFANA_OTLP_TOKEN=your-grafana-otlp-token

# Enable detailed analytics (optional)
ENABLE_TELEMETRY=true
TELE_SALT=your-unique-salt
APP_VERSION=1.0.0

Self-Hosting Analytics

You can self-host all analytics services for complete control:

# Use docker-compose with monitoring profile
docker-compose --profile monitoring up -d

This starts:

• Prometheus — Metrics collection and storage
• Grafana — Visualization dashboards
• Loki (optional) — Log aggregation
• Promtail (optional) — Log shipping

Privacy & Data Protection

Telemetry: TimeTracker can optionally send anonymized usage data to help improve the product (errors, feature usage, install counts). All telemetry is opt-in. No personal data is collected. To disable telemetry, set ENABLE_TELEMETRY=false or simply don't set the environment variable (disabled by default).

What we DON'T collect:

• ❌ Email addresses or usernames
• ❌ IP addresses
• ❌ Project names or descriptions
• ❌ Time entry notes or client data
• ❌ Any personally identifiable information (PII)

Your rights:

• 📥 Access: View all collected data
• ✏️ Rectify: Correct inaccurate data
• 🗑️ Erase: Delete your data at any time
• 📤 Export: Export your data in standard formats
