Our Privacy-First Commitment

At Otlet, privacy isn't just a feature, it's our foundation.

We believe that:

  • Your data belongs to you and only you
  • Great software can and should respect user privacy
  • Privacy and functionality can coexist without compromise
  • Transparency builds trust

We've built Otlet from the ground up with these principles in mind, making technical and business decisions that prioritise your privacy over everything else.

Privacy Policy

Last Updated: February 2026

The Short Version

Otlet runs entirely on your Mac. We don't collect, transmit, or store any of your data. Period.

What Otlet Accesses

Otlet needs to read your files and folders to do its job. Here's exactly what it accesses and where that data stays:

  • Folder names and structure — to build your folder map and detect issues. Stored in a local SQLite database on your Mac.
  • File names and metadata — to suggest where files should go. Stored in a local SQLite database on your Mac.
  • File contents (text, images) — to categorise files using AI. Processed in memory, never stored raw.
  • Folder access bookmarks — to remember which folders you've authorised. Stored in macOS Keychain and local database.
  • Operation history — so you can undo any action. Stored in a local SQLite database on your Mac.

What Otlet Does NOT Do

  • No cloud uploads — all AI analysis happens on-device using Apple's ML framework
  • No accounts — no sign-up, no login, no user profiles
  • No telemetry — no usage tracking, no analytics, no crash reporting to external services
  • No network calls — Otlet makes zero network requests for file analysis
  • No data sharing — your files, folders, and organisation patterns are never shared with anyone

AI Processing

Otlet uses 5 Apple ML models that run entirely on your Mac:

  • Models are bundled with the app (not downloaded)
  • File analysis happens in memory and is not persisted in raw form
  • Only classification results (category, confidence score) are stored locally
  • AI models never see your data in aggregate — each file is analysed independently

macOS Security

Otlet follows Apple's security model:

  • Sandboxed — the app can only access folders you explicitly authorise
  • Security-scoped bookmarks — folder access persists across app restarts without re-prompting
  • No Full Disk Access — Otlet only sees what you give it permission to see

Your Data, Your Control

  • Undo anything — every operation Otlet performs can be reversed
  • Revoke access — remove any folder from Otlet's access in Manage Folder Access
  • Delete everything — removing Otlet removes all local data (database, bookmarks, preferences)

Data Storage Location

All Otlet data is stored in your app sandbox:

~/Library/Containers/app.otlet.mac/Data/

This folder is automatically removed if you delete Otlet from your Mac.

Mac App Store

Otlet uses standard Mac App Store licensing for purchase verification, which is handled directly by Apple and not by us. We have no access to your Apple ID or payment information.

Children's Usage

Otlet is safe for users of all ages. Since all data remains locally on your device and we have no means to collect or access it, there are no special privacy concerns related to children's usage.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
