This is a 100% browser-based service, meaning all your data, including notes, is stored directly in your browser and never sent to our servers. We don’t collect or track any personal information, and no data is synced or shared anywhere. The only third-party service we use is Cloudflare, which helps with website performance and security, but they do not have access to your data. Since everything is stored locally in your browser, it's important to keep your browser secure and back up your notes. We do not track or store any information about your use of the site.
