Sirenetta Privacy Policy

1. Information collected by the Application

The Application does not collect personal information. It provides no accounts or sign-in, and it contains no analytics, advertising, tracking or crash-reporting functionality of its own. The Application does not transmit diagrams, files, settings or any other information relating to the user to the Developer or to any third party.

2. Files and processing

The Application opens and saves the Markdown and Mermaid files that the user selects, on the user's Mac. It operates within the macOS App Sandbox and accesses only the files that the user opens or saves through the system's file panels. Diagrams are rendered on the user's Mac by a copy of Mermaid included in the Application and are not uploaded.

3. Information stored on the user's device

The following information is stored on the user's Mac and is not transmitted to the Developer:

• The user's settings (for example, the default theme and author name) and the list of recently opened documents, which are stored by macOS.
• A trial record. Editing diagrams inside Markdown files is free for seven days of use. To count those days, the Application stores in the user's Keychain the date on which the trial started, the number of days of use, and the date on which the Application was last used. This record is not linked to the user's name or Apple Account.

4. Quick Look extension

The Quick Look preview extension (the Finder spacebar preview) reads the file being previewed and renders it on the user's Mac. It transmits no information.

5. Network access

The Application does not communicate with servers operated by the Developer. Its network communication is limited to the purchase and restore functions provided by macOS, which communicate with Apple's App Store as described in section 6.

6. Purchases

The Application is free to download and offers one optional in-app purchase, which unlocks editing inside Markdown files after the trial. Purchases are processed entirely by Apple through the App Store. Apple processes payment and Apple Account information in accordance with Apple's Privacy Policy. The Developer does not receive the user's name, email address, payment details or Apple Account. The Application requests from Apple only whether the Apple Account in use has purchased the unlock.

7. Information provided by Apple

Where a user has enabled "Share With App Developers" in the analytics settings of macOS, Apple may provide the Developer with anonymous, aggregated statistics about the Application, such as crash counts. These statistics do not identify individual users and are not used for tracking. Apple also provides the Developer with sales and proceeds reports, which contain no personal information about purchasers.

8. Communications with the Developer

A user who contacts the Developer by email provides the Developer with the user's email address and the content of the message. This information is used solely to respond to the user, is retained only for as long as necessary for that purpose, and is not sold or disclosed to any third party other than the email provider that carries the message.

9. The Website

The Website is a static website. It does not set cookies and does not use advertising or third-party analytics. The Website is hosted on Amazon Web Services. The hosting infrastructure keeps standard server logs, which include the date and time of each request and the visitor's IP address. These logs are retained for a limited period (currently 90 days) and are used by the Developer only to produce aggregate traffic counts and for security and operation of the Website, not to identify visitors.

10. Children

The Application is a general-purpose tool and is not directed at children. It does not collect personal information from any person, including children.

11. Access, correction and deletion

The Developer holds no personal information collected through the Application and therefore has none to disclose, correct or delete. Correspondence sent to the Developer will be deleted on request. This Privacy Policy is intended to comply with the Personal Information Protection and Electronic Documents Act (Canada).

12. Changes to this Privacy Policy

The Developer may update this Privacy Policy. The date of the latest revision appears at the top of this page, and the current version is published at this address. Any change that affects what the Application collects will also be described in the Application's release notes.
