ONA.UNO is designed to keep your content under your control. Your documents, web clippings, emails, notes, and feeds stay on your Mac — ONA.UNO reads them locally and builds its index locally. This page explains exactly what stays on your machine, what leaves it when you use cloud AI, and what minimal metadata ONA.UNO sends to its own services.
Your content stays local
Your original files remain in their original locations (your folders, your mail, your Obsidian vault). ONA.UNO's index, database, and all generated content — summaries, titles, tags, embeddings, chat history — live on your Mac.
ONA.UNO does not upload or store your content on its own servers. Ever.
What happens when you use cloud AI
When you use features that require cloud AI (chat, deep summaries, or the full Online mode pipeline), your content flows from your Mac to the AI provider through OpenRouter over encrypted connections:
- Online mode: your Mac → OpenRouter → AI provider (for all pipeline stages)
- Mixed mode: most processing happens locally on your Mac; only chat and full summaries go through the cloud
- Chat and deep summaries (both modes): your Mac → OpenRouter → AI provider
If you have content that must never be processed by cloud AI, simply don't use chat or full-summary features for those items. The automatic pipeline in Mixed mode handles titles, tags, micro summaries, and embeddings entirely on your Mac.
ONA.UNO licensing service
ONA.UNO uses a small backend service for licensing and tracking your Advanced AI action quota. This is what it stores:
- License and customer identifiers
- Device installation identifier
- Plan status (Free or Pro)
- Advanced AI action counts and quota window timestamps
- Checkout and session identifiers
What it does not store:
- Your documents, emails, notes, or any file content
- Chat messages or responses
- Summary text
- Any file payloads
This licensing communication is essential for the app to work and is completely separate from optional analytics.
Analytics and crash reporting
Analytics (Countly): ONA.UNO collects lightweight usage analytics — things like feature usage counts, source-type adoption, and app/OS version. No content from your documents, chats, or summaries is ever included. You can disable analytics entirely in Settings.
Crash reporting (Firebase Crashlytics): If ONA.UNO crashes, it sends technical diagnostic data (stack traces and crash metadata) to help fix the issue. No content from your documents or chats is intentionally included in crash reports.
Cookies: The websites ona.uno and doc.ona.uno do not use cookies.
Third-party services
Here's every external service ONA.UNO communicates with:
- OpenRouter — routes AI requests to providers
- AI providers (via OpenRouter) — execute model inference
- Polar — handles license purchases and checkout
- ONA.UNO backend — licensing and quota metadata only
- Countly — optional usage analytics
- Firebase Crashlytics — crash diagnostics
- Tailscale — optional, only if you enable remote Web Access
When you use cloud AI features, your content is processed by servers in the United States (OpenRouter, Firebase Crashlytics) and potentially other countries depending on the AI model provider selected by OpenRouter. All connections use encrypted transport.

Your rights under Swiss law
The websites ona.uno and doc.ona.uno do not collect personal data.
In-app analytics can be disabled in Settings and are not linked to your identity.
For free licenses, the app records quota usage for the Advanced AI action limit. To stop this, remove your free license in Polar's settings. You can then request deletion of existing quota data under the Swiss Federal Act on Data Protection (DSG).
