Privacy policy and privacy notice

Summary

Kitty Calendar is built on a strict privacy-first architecture. The desktop application runs completely locally on your Mac, requires no accounts, and never connects to the internet to collect or send personal data (on the App Store listing we declare “Data Not Collected”). In this policy, we clearly separate the desktop application from this website.

Data controller

The party responsible for this application and this website is Sxnnyside Project. For any privacy inquiry, contact [email protected].

Desktop app: Your calendar

With your explicit permission, Kitty Calendar accesses the system calendar through native macOS APIs exclusively to display your events and to create, edit, or delete the ones you choose. New events are saved in a calendar called “Kitty Calendar” inside Calendar.app.

That information is managed by macOS locally on your device. If your calendar synchronizes with iCloud or another provider, synchronization is performed by the operating system according to your settings, never by Kitty Calendar. You can revoke this permission at any time in System Settings › Privacy & Security › Calendars.

Desktop app: Data stored on your Mac

The app stores your preferences (theme, chosen cat, sound, launch at login) and the state of your virtual room (placed items) locally on your Mac. This data never leaves your device.

If you choose to export a backup, it is written only to the local file or folder you specify.

Desktop app: Local notifications

Event alerts are local notifications scheduled on your Mac by the operating system. We use no push notifications and no intermediary servers.

Desktop app: Zero telemetry or tracking (Privacy-First)

The macOS desktop application contains NO analytics, advertising, usage telemetry, or third-party tracking SDKs. Black Pillar is NOT present in the desktop application.

If you have enabled voluntary diagnostics sharing with developers in macOS, Apple may share anonymous system crash reports with us according to your macOS system settings.

This website: Cloudflare hosting

This website is hosted and delivered through Cloudflare. Like any web host, Cloudflare processes essential technical request data (such as IP address and browser user-agent) to deliver pages and defend against cyberattacks, governed by its own privacy policy. We do not receive or store these logs.

This website: Anonymous telemetry via Black Pillar

On this website, we use Black Pillar, our own anonymous telemetry and observability service. We emphasize that Black Pillar runs EXCLUSIVELY on this website and NEVER in the desktop application.

From your web browser, Black Pillar receives only anonymous performance metrics: visited page path, load duration, clicks to the App Store link, and generic error categories if a script fails. No tracking cookies are used, no identifiers are stored in your browser, and no names, email addresses, or precise locations are collected.

This website: Self-hosted fonts and contact

All typography on this website is 100% self-hosted locally in WOFF2 format on our own servers. We do not use Google Fonts or connect to external style servers, ensuring your IP address is never shared with third-party font providers.

If you email us at our support or legal addresses, we will use your address and message solely to answer your request.

Your rights

Because we collect no personal data through the app and maintain no user profiles on the website, we hold no personal information about you to access, rectify, delete, or object to. You can still exercise your access, rectification, cancellation, and opposition (ARCO) rights under Mexico's LFPDPPP, as well as rights under GDPR or CCPA, by writing to [email protected]. Your calendar data is controlled directly through macOS.

Children

Kitty Calendar is designed for all audiences and does not request, collect, or store personal information from children.

Changes to this policy

If the app or website updates its privacy practices, we will post the changes on this page along with the updated date.
