Listio is a privacy-first application. Your lists and data are stored exclusively on your device using your browser's IndexedDB. We do not collect, transmit, or store any of your personal data on our servers.
All your lists, items, and preferences are saved locally in your browser's IndexedDB. This data never leaves your device. No account is required, and no data is synced to any external server.
You can delete all your data at any time by clearing your browser's site data for this app, or by uninstalling the app from your device.
If you choose to share a list, its content is encrypted on your device before being sent (end-to-end encryption). The encryption key is part of the share link and is never transmitted to our server — the server only stores and relays encrypted data it cannot read.
Shared lists are automatically deleted from the server after 30 days of inactivity. Anyone who has the link can read and edit the shared list, so only share it with people you trust.
Listio uses Google AdSense to display ads. Google may use cookies and similar technologies to show you personalized ads based on your browsing activity.
Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this and other sites. You can opt out of personalized advertising by visiting Google Ads Settings.
For more information about how Google uses data, please visit Google's Privacy Policy.
Listio itself does not use cookies. However, Google AdSense may set cookies on your device for advertising purposes. These are third-party cookies governed by Google's privacy policy.
The only third-party service integrated into Listio is Google AdSense. We do not share any data with third parties, as we do not collect any data in the first place.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date. We encourage you to review this page periodically.
If you have any questions about this privacy policy, you can contact us at [email protected].
