Privacy Policy

Your calendar

The extension adds or removes a checkmark in event titles inside Google Calendar. Google Calendar saves these changes. Calendar information is never sent to me, and the extension has no account, backend, or analytics.

Chrome stores a small amount of data about installation and use to decide when to offer a review prompt. It contains no event titles and is removed when you uninstall. Uninstalling does not remove checkmarks already saved in your calendar.

Website analytics

Cloudflare hosts this website. I use Cloudflare Web Analytics to see aggregate traffic and page performance, such as page views, referring websites, country, and device type. It uses no analytics cookies or visitor profiles. I do not collect product events or session recordings.

Email and privacy requests

Cloudflare forwards support emails to my personal Gmail inbox. Google stores your email address, message, attachments, and normal email metadata so I can read and reply. I reply from my personal email address.

I use these messages to answer you and improve the product, and keep them only while needed for the conversation and relevant follow-up. They are not included in analytics.

I’m Victor Cheeney, the maker of this product and responsible for your personal information. For questions or to ask me to delete a support conversation, email support@calcheckoff.app.

These services also process data under their own policies: Cloudflare and Google.
