Privacy Policy

Last updated: July 2026

Sirocco is a macOS app that uploads files from a folder you choose to a cloud storage account you own. This policy describes what the app can access and what happens to your data. The short version: your files go directly from your Mac to your own Dropbox or Google Drive. We never see them.

No Sirocco servers

Sirocco has no backend. The app talks directly to the Dropbox and Google Drive APIs over TLS from your Mac. Your files, file names, and folder structure are never sent to us or to any third party other than the cloud provider you linked.

What the app stores on your Mac

OAuth tokens for the accounts you link, stored locally in your user Library with owner-only file permissions. You can revoke them anytime by unlinking the account in Sirocco or from your provider's security settings.
A sync index — a local record of what has been uploaded (paths, sizes, timestamps) so unchanged files are skipped.
Preferences such as your chosen folder and schedule.

Cloud provider access

Dropbox: Sirocco requests the scopes needed to upload files, read file metadata, create shared links, and read your account's name, email, and storage quota (shown in the app).
Google Drive: Sirocco uses the drive.file scope, which means it can only see and manage files and folders it created for you. It cannot read anything else in your Drive.

Sirocco's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Shared links

Creating a shared link is an explicit action you take per file. Links are created by your cloud provider under your account and follow that provider's sharing settings. Sirocco copies the link to your clipboard and does not store or transmit it elsewhere.

Purchases

Sirocco Pro is sold through Polar (polar.sh), who acts as merchant of record and processes payment details; Sirocco never sees your card information. The app validates your license key against Polar's API. See Polar's privacy policy.

Analytics and tracking

The app contains no analytics, telemetry, advertising SDKs, or crash reporters.

Changes

If this policy changes, the updated version will be posted at this address with a new "last updated" date.
