Local custom colors, no Calendar data writes.

Calendar Palette Pro adds custom colors in your browser and keeps saved palettes on your device.

No separate Google login

Calendar Palette Pro does not ask you to sign in with Google inside the extension and does not use Google OAuth.

No Calendar API writes

The extension applies local visual overlays in desktop Google Calendar. It does not create, edit, delete, or recolor events through the Google Calendar API.

Browser-local storage

Saved colors, event-color mappings, extension settings, and activation status are stored in Chrome extension storage on your browser profile.

License activation

License activation sends your license key and a browser-generated device identifier to Calendar Palette Pro servers to verify that the extension is unlocked.

Data handling

The extension reads the visible Google Calendar page so it can add custom color controls and apply local color styling. If you apply a color to an event, the extension may store the visible event title and local event identifier in Chrome extension storage so the color can be applied again in that browser.

Calendar event titles, event details, and saved color mappings are not sent to Calendar Palette Pro servers. The extension does not use the Google Calendar API and does not create, edit, delete, or recolor events in your Google account.

Purchases are processed by Stripe. Calendar Palette Pro stores license records such as purchaser email, Stripe checkout identifiers, license status, activation count, and hashed activation tokens. Card numbers and payment credentials are handled by Stripe and are not stored by Calendar Palette Pro.

License emails may be sent through Resend. Calendar Palette Pro uses license and purchase information only to provide access to the extension, handle refunds, prevent abuse, and provide support.

The extension does not sell user data, does not use user data for advertising, and does not use or transfer user data to determine creditworthiness or for lending purposes.
