Notestopin ("we", "our", or "us") respects your privacy. This Privacy Policy explains how we handle your data when you use the Notestopin browser extension or mobile capture web app. In short: Your notes live on your device. We do not collect, transmit, or maintain a server-side copy of your note content.
Local Storage: Notes, tags, and metadata created in the browser extension are stored with the Chrome Storage API (chrome.storage.local). Notes created in the mobile capture web app are stored in that browser or installed web app using Web Storage (localStorage). Note content is not sent to a Notestopin server and leaves that storage only when you explicitly export it. Browser and installed-app storage can be separate on some devices, so automatic cross-device sync is not implied.
Feedback: If you choose to use the feedback form within the extension, the name, email, and message you provide are sent securely to our support team via Web3Forms and used solely to respond to your inquiry.
Pseudonymous usage analytics: Notestopin sends a small set of usage events (for example: install, update, note created, and note count) through our back.notestopin.com endpoint for processing by PostHog. Each event carries a random user identifier (UUID) generated on your device. The events do not include your Pinterest account or note content. If you uninstall the extension, the uninstall page receives this UUID, the extension version, and aggregate note counts so we can understand uninstall trends.
Optional Cloud Sync survey: If you choose to submit the Cloud Sync survey, your selected answer, optional message, and optional email address are sent through the same analytics endpoint for product research and, when you provide an email, to contact you about early access. This information is sent only after you press the survey's submit button and is associated with the random identifier described above.
Pinterest: Notestopin interacts with Pinterest.com to display your notes on pin pages. We do not transmit your Pinterest browsing history, login credentials, or pin data to any external server.
Mobile Share Sheet: Android may pass the Pinterest URL you choose to share to the Notestopin capture route. On iPhone or iPad, an Apple Shortcut you create can place that shared URL in the capture page address. The URL is used in your browser to attach the note to the correct Pin; Notestopin does not receive it through a note-storage API.
PostHog: Processes the pseudonymous usage events and optional Cloud Sync survey responses described above.
Web3Forms: Processes feedback form submissions that you explicitly send.
We request the minimum permissions necessary for the extension to function:
storage: To save your notes locally.host_permissions (Pinterest): To inject the note editor into Pinterest pages.host_permissions (Web3Forms): To send feedback only when you submit the feedback form.host_permissions (Notestopin analytics): To send the pseudonymous usage events described above. These events do not contain note content.Notestopin's use of information received from Chrome extension APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. We do not sell user data, use it for personalized advertising, or transfer it for creditworthiness or lending purposes.
We may update this Privacy Policy from time to time. If we make significant changes, we will notify users through the extension or this website.
